Description
Technical field
The utility model is related to walnut shell-breaking to take benevolence device, and in particular to self-positioning pre-breaking shell spiral in the same direction is classified flexibility certainly
Walnut extruding shell-cracking kernel-taking device.
Background technology
Walnut, is English walnut with almond, cashew nut, fibert and referred to as world-renowned " four big dry fruits " also known as English walnut, Qiang peach
The perennial deciduous tree of section's Juglans, the Central Asia is its original producton location.By constantly exploration and practice, China walnut cultivated area is about
More than 1300000 kms, its area and yield occupy first place in the world.
Walnut whole body is precious:Walnut kernel, rich in abundant nutriment, the trace element that also various human bodies need, no
Only there is good health-care effect to human body, while also preventing various diseases;Walnut shell, is juglandaceae plant English walnut ripening fruits
Endocarp, be good Chinese medicine.This product is bitter in taste, puckery, flat, enters spleen, lung, kidney channel, there is clearing heat and detoxicating, astringing to arrest bleeding it
Work(, it is adaptable to metrorrhagia, acute mastitis, mange;Additionally, walnut shell good hydrophilic property, the advantages of oil resistant is soaked.Because of durability and elasticity preferably,
And can and other abrasive mixeds and use, so being also comparatively ideal polishing grinding material.In metal cleaning industry, walnut shell passes through
Cleaning and the polishing material of metal are can serve as after treatment.The gear dress of such as aeroengine, circuit board and steamer and automobile
Putting can be cleaned with the walnut shell after treatment.Walnut shell has certain elasticity, restoring force after being ground into superfine particle
With huge endurance, so being suitable as abrasive polishing milling cutter and the various handwares of skin processing, jewellery, operating parts
Deng.Diaphragma juglandis, also known as English walnut clothing, cracker, English walnut are every being the wooden barrier film in juglandaceae plant English walnut fruit stone.The traditional Chinese medical science thinks,
This product is bitter in taste, puckery, flat, enters spleen, kidney channel, there is the work(of reinforcing the kidney and controlling noctural emission, can also prevent many diseases.A variety of benefits, cause walnut
Increasingly pursued and liked by people, so the increasing degree of its output is increasing.
As walnut yield and the market demand are constantly increasing, walnut deep processing is increasingly highlighted in also turning into research and production
Problem.It is the primary premise of deep processing that walnut shell-breaking takes benevolence.Because walnut shell is main by lignin, cellulose and hemicellulose group
It is hard into, walnut shell and thick, it is in irregular shape, inside have multiple separations, shell benevolence gap is small, this just give peel off take benevolence increased it is very big
Difficulty.Because process technology falls behind, without ripe walnut shell-breaking machinery, to ensure shell-breaking rate and rate of perfect kernel, many walnuts
Processing producer still takes the mode of manual shell-cracking kernel-taking, such as " hickory nut peeled by hand " method, i.e., the hammer being made using flexible material
Hickory nut in mould is manually tapped.Also, current existing crust breaking device is difficult suitable family and uses, shortcoming master
It is expensive if bulky.
The economic benefit of walnut product is closely bound up with the rate of perfect kernel of walnut, and walnut kernel percentage of head rice is higher, and economic benefit is got over
Height, rate of perfect kernel high and high efficiency are the focuses of contemporary walnut shell-breaking kernel-taking machine competition.As domestic and foreign scholars are to mechanization walnut
The intensification of hulling machine research, many new walnut hullers occur.These shell-cracking kernel-taking machines exist overall deficiency be:Leakage
Not exclusively, shell-breaking rate is low, and loss late is high for stripping or broken shell, and dew benevolence rate is low.For example some broken walnut shell-breaking rates for taking benevolence shell machine are low, core
Peach kernel rate of perfect kernel is higher;And some shell-cracking kernel-taking machines improve shell-breaking rate too much, and damaging of have ignored that walnut kernel is subject to, cause
Walnut kernel percentage of damage is higher, at the same these walnut shell-breakings to take benevolence device poor to the walnut adaptability of different cultivars, when walnut chi
Very little when changing, the broken shell effect of device declines.
In the prior art, realize that walnut shell-breaking takes benevolence and mainly has physics and chemical attack two ways at present, wherein chemistry
Due to the bad control in practical operation, walnut kernel is vulnerable to corrosion for corrosion, while also increasing the pretreatment of walnut and rear place
Science and engineering sequence, therefore people are reluctant to receive this mode to process the bad pollution that can also cause to environment.It is most in the market
Shell-cracking kernel-taking exactly is carried out to walnut using the physical characteristic of walnut, including:Grind stranding method, impingement method, shearing method and squeeze
Platen press and the shatter method of ultrasonic wave.Preceding four kinds of methods using there is certain gap between walnut shell and benevolence, are filled by machinery
Put rigidly applying pressure and broken effect is caused to shell, as long as the stroke of applying power is less than the gap between shell benevolence, Jiu Huibao
Shield walnut kernel preserves from.But because the species of walnut is different, then the size and shape of walnut also has the hardness of walnut shell
Will be different, this stroke for having resulted in walnut shell stress is not changeless, so above-mentioned preceding four kinds of methods are in broken shell
The positioning or size fractionation problem of walnut will be considered.The 5th kind of shatter method of physical method ultrasonic wave is to utilize ultrasonic wave by core
The shatter effect so as to reach separation of hull from kernel of shell of peach, this method also has without the concern for the size shape of walnut and classification
Orientation problem.But, it is immature due to method, it is difficult to ensure that walnut shell it is shatter while walnut kernel will not be caused necessarily
Injury.
A kind of pneumatic shell-breaking machine of walnut, Patent No. have been invented by Xinjiang Agricultural Univ:201310144581.1.The invention by
Frame, transmission control device, feed mechanism, hulling machine composition, are equiped with hulling machine, by being even mounted in Working gantry in frame

The wall of case one is slotted, and feed mechanism is equiped with against groove lower section, and it is by chain side by side, interval even turning on chain
Roller, the rolling plate of support transfer roller and tightener sprocket composition.
The shortcoming of the device is rate of perfect kernel not high, needs to position walnut before processing, big to walnut kernel injury, processing
Operation is various, and secondary injury is caused to walnut kernel, is more expensive to manufacture.
A kind of party of Shaanxi Province Shangluo City just good invention walnut shell-breaking kernel-taking machine, the patent No.:201220548222.3, its
Broken shell part includes piston bush, there is piston inside piston bush, and piston connects one end of broken shell spring, the broken shell spring other end
Connection broken shell spring positioning pillars, the broken shell spring positioning pillars pass through the location hole on piston bush, also comprising perpendicular to work
Plug sleeve axis and and piston connect piston pin, also comprising the rotating shaft perpendicular to piston bush axis being installed on piston bush, institute
State rotating shaft one end and cam knife is installed, other end is handle, and the cam knife can promote work around the operation curve that rotating shaft rotates
Plug pin is moved forward and backward in the spacing hole on piston bush and makes piston and block contact;Block on the extended line of piston axis,
The block is fixedly installed on piston bush.Walnut and block are clashed into using piston movement during work, broken shell purpose is reached.
The shortcoming of the device is that lasting reciprocating percus-sion proposes requirement very high to spring, in addition, under high-speed impact,
Walnut kernel is highly susceptible to damage, and rate of perfect kernel can be substantially reduced.
At present, in addition to the method for taking benevolence by hand, walnut shell-breaking takes benevolence following several method:Centrifugal bump type broken shell
Method, chemical corrosion method, vacuum shell-cracking kernel-taking method, ultrasonic wave broken shell method, mechanical shell-breaking method.First method, the walnut after centrifugation
High-speed impact wall deforms shell until rupturing, but the broken benevolence produced after broken shell is more, so method is undesirable;Second side
Method, whard to control in practical operation Chinese medicine consumption, walnut kernel is vulnerable to corrosion, processes the bad dirt that can also cause to environment
Contaminate, therefore method is seldom applied;Third and fourth kind of method, apparatus expensive, broken shell cost is too high, and broken shell effect is not ideal enough.The
Five kinds of methods, equipment is simple, low cost, and broken shell effect can be lifted by improving modular construction, therefore the method obtains more
Exploratory development and application.
Substantial amounts of experiment has been carried out to nuts such as almond, pine nuts both at home and abroad, mechanical property and the influence of nut has been probed into
The factor of broken shell effect, it is indicated that the factor such as moisture content, loading direction is to nut cracking power, deflection, broken shell trend and whole
Benevolence rate etc. has a certain impact.Shi Jianxin, Wu Ziyue et al. combine limited element analysis technique and pass through broken shell of the lot of experiments to walnut
Principle and mechanical property are studied, optimal force application location and mode when have found broken shell.Yuan Qiao rosy clouds et al. are by right
The experimental study of the board-like ginkgo hulling device of roller draw spacing it is excessive or it is too small be all unfavorable for shelling.The excessive amount of compression of spacing reaches
Less than the critical reduction needed for broken shell, husking yield declines;Spacing is too small, and amount of compression is excessive, and nutlet cracking rate increases.Li Zhong is new et al.
By the inspiration of fixed gap extruding (transverse shear stress and longitudinal direction extrude) experiment, " conic basket type broken shell model " is established, have studied to core
The maximally effective force direction of peach broken shell and position, and propose the structural factor of rejuvenator, such as broken shell gap, broken shell plate it is hard
Degree, influence of the rate of feeding to broken shell effect.Song of HeFei University of Technology leads exhibition with theory of thin shell and fracture theory to internal force
It is analyzed with displacement and points out two pairs of normal force more conducively broken shells, while points out that carrying out broken shell to Gorgon fruit by way of rubbing wants
Washboard is designed into the shape consistent with nut, i.e. washboard after deformation will have certain flexibility and hardness, and washboard with
The appropriate larger requirement to meet shelling that coefficient of friction between Gorgon fruit should be chosen.
At present, domestic common mechanical descaling process equipment is broadly divided into four classes by method for stripping shell classification:Extrusion, shock
Method, shearing method and stone roller stranding method.The continuous walnut huller of Wu Ziyue researchs uses two gear disk-toothed plate type and peels off principle.It is continuous
After walnut is fed into peeling apparatus, round tooth disk is clamp-oned in driving continuous walnut in rotation to gap, the tooth of a determining deviation
Sharp constantly walnut extruding shell surface so that crackle constantly extends, and last walnut shell substantially completely ruptures, broken shell and walnut kernel
Dropped out downwards by minimum clearance.The main classification by cone roller formula of the Double Cellular-Roller Walnut Splitting Machine of Zhang Zhongxin research and development fills
Put and roller indent type shedding motion two parts are constituted, grading plant is by big a pair ends to big end, small end to the tapered roller of small end
Composition, two roller gaps become larger from big end to small end.It is that a pair of diameter identical cylinders are squeezed to roller indent type shedding motion
Pressure roller, its upper band pocket, pocket size becomes larger from big end to small end.Two pairs of carrying roller relative rollings respectively, after classification
Walnut is crushed after falling into corresponding pocket under the squeezing action of two rollers, is then collected by the slide plate that discharges.Wang Xiaoxuan[21]Deng
The secondary rejuvenator of centrifugal walnut that people develops is crushed walnut using impingement method.In the frictional force and plate of supporting plate
Impetus under, fall centrifugation plate on walnut with centrifugation plate rotate, when be centrifuged plate reach certain rotating speed after, walnut
Can be departed from certain speed and flown out, collided completion broken shell with bucket is clashed into.Can be adjusted by the rotating speed for adjusting centrifugation plate
The size of walnut impact, and then comparatively ideal broken shell effect can be obtained.The device for taking unbroken kernels from walnuts of brave research and development is opened by base
Seat and top cover composition.The first half of pedestal is a round platform, and round platform top surface has a recessed chamber of peeling off, and its inside edge is with a circle
Sawtooth.During work, walnut is placed on the sawtooth in chamber of peeling off, is pushed down walnut with the top cover with rubber blanket, start motor just
Walnut shell can be sawed out a breach, walnut shell can be peeled off after sawing out 4 to 6 breach.Chai Jinwang is ground using friction and rubbed with the hands
The walnut huller of principle research and development broken shell is carried out to walnut using with the inside and outside mill of teeth groove.Outer mill is fixed in frame, interior
Mill is rotated under the drive of motor.Gap implosion shelling of the walnut in inside and outside mill.After suitable granularity is crushed to, by baffle plate
Fall on feeding plate in same gap with interior mill bottom.The machine can not automatically adapt to the size of walnut, and due to current walnut product
Plant various, not of uniform size, therefore there is certain defect in actual applications, rupture various sizes of walnut, it is necessary to change chi
Very little different internal-and external diameter.
But the subject matter that most decorticators are present is:Hulling rate is low, and many decorticator leakage strippings or broken shell not exclusively, are peeled off
Rate 80%, it is even lower;Loss late is high, and height dew benevolence rate is low.Due to broken shell not exclusively, part fragment walnut kernel is entrained in hardly possible in broken shell
To take out, the kernel loss late of some decorticators is up to 20%, and height reveals benevolence rate about 60%;Kernel integrality is poor, and many is peeled off
Machine pursues the raising of hulling rate simply, causes walnut kernel percentage of damage high;Bad adaptability, in Walnut Cultivars, size specification, shell
When change occur in the factors such as shape, equipment of peeling off performance of peeling off just is deteriorated.The broken shell gap of most mechanical shell-breaking equipment is all
It is fixed, and because walnut geomery is irregular, walnut batch is put into, the walnut for not meeting gap size often must
Less than effective broken shell, walnut is oversized to cause walnut shell overcrushing, walnut kernel to suffer damage, and walnut is undersized to lead
Cause cannot get broken shell, need to carry out size classification to walnut before broken shell for this.At present mechanically to walnut size point
The equipment of level mainly has 3 kinds.1) rolling bar type classifier, all rolling bar relative level are parallel, and the spacing between rolling bar is by small change
Greatly.When walnut is rolled on rolling bar, when rolling bar spacing exceedes walnut diameter, walnut just falls into lower section and divides in fruit groove accordingly.
2) double-roll type grader, double roller is with the horizontal certain angle of inclination and angled between double roller, rotates against.By
There is angle between double roller, the classification spacing between double roller gradually increases, walnut is rolled down along seam under gravity, when being rolled to double roller
Between spacing more than fruit footpath part when, walnut just falls into point fruit groove between two rollers.3) drum-type grader, has some in roller
Layer roller unit, uniformly aperture is covered with every layer of roller unit, and the small aperture in same layer roller is identical, different layers roller
Small aperture is different, and aperture in every layer increases successively from inside to outside.Roller uniform roll, walnut send from drum overhead
Enter, conveyed along roller appearance, walnut sequentially passes through the roller in different layers aperture, is classified successively from small to large.
Separation of hull from kernel is that walnut shell-breaking takes one of difficult point of benevolence.Domestic preferably separation method and separation equipment occur too
It is few.Although the method and apparatus for occurring can realize separation of hull from kernel, equipment Cheng Fenggao, complex process, separation rate is low.At present, profit
The device for separating walnut shell and benevolence with Mechanical Method is main following several:Clearer separating husk benevolence device.The device is by a pair of total lengths
The roller that contacts with each other is constituted, and rollers outer surface encloses flannelette, relatively rotates and be inclined relative to horizontal.When walnut shell and meat is mixed
From after high-end feeding, the smooth walnut kernel in surface is difficult the groove fallen between two rollers by fine hair adhesion and slides downwards compound material
Until from bottom discharge, coarse walnut shell is adhered to by fine hair, finally gets over clearer and fall into hopper, in order to reach certain dividing
From effect, the general device is made up of multipair clearer and is separated repeatedly.Due to walnut shell and fracture port all hairiness of benevolence
Thorn, can adhere to the therefore device separating effect bad by lint.The walnut shell and meat winnowing machine of Dong Yuan morals et al. research and development is used
Winnowing type principle is separated to walnut shell and meat.Result of the test shows that air force and wind cavity length have aobvious to rate of kernel in hull
Influence is write, wind cavity length has pole significant impact to rate of hull in kernel, and feed quantity has pole significant impact to benevolence loss late in road high.
Qingdao Technological University Li Changhe teach research team walnut shell-breaking take benevolence separating technology with equipment, walnut classification and
Walnut shell and meat separates and has carried out going deep into systematic research.Design the walnut shelling and picking device of research and development, integrated automation, shell-breaking rate

Cylinder, walnut kernel material enters walnut shell and meat separated region under wind model effect, and walnut shell material major part enters walnut shell
Conveyor zones, small part enters walnut shell and meat separated region.The variable-pitch auger being fixedly connected on helical blade inner wall of rotary drum is defeated
Blade mechanism is sent, the hand of spiral is dextrorotation, when helical blade roller is rotated clockwise, helical blade plays conveying walnut
The effect of shell benevolence material, material conveying direction is to be delivered to import direction by Way out.In walnut shell and meat separated region, walnut
Shell benevolence material is circumferentially delivered to eminence by helical blade II, while helical blade II is to the oriented import direction of walnut shell and meat material
The effect of transport;After reaching a certain height, walnut shell and meat material under aerial throwing, with the initial velocity to import direction.In wind
Under power conveying effect, walnut kernel is fallen in walnut kernel conveyor zones by less wind-force;Walnut shell is sent by larger wind-force
Enter walnut shell conveyor zones.In walnut kernel conveyor zones, walnut kernel is delivered to helical blade rolling by the helical blade III of fine pitch
Cylinder Way out output, because the pitch of helical blade III is small, coefficient of friction is small, typical helical feed is formd in this region
Effect, walnut kernel does not receive windage, walnut kernel to be delivered to helical blade drum outlet direction by the helical blade III of fine pitch
Output, falls into walnut kernel collector.
In sum, to take benevolence technical approach many for existing walnut shell-breaking, there is oneself, but also have very serious lacking
Point, some devices have simply solely pursued the function of one side and effect is less desirable in terms of causing other, so that can not
Ensure that the rate of perfect kernel of walnut also has shell-breaking rate and shell-breaking efficiency.So, such device cannot comply with market demand and
Development.

The self-positioning pre-breaking shell device extruding mechanism of vee-block:
First the extruding vee-block mechanism simplifying on machine into equivalent mechanism as shown in figure 20:The plates of B I are squeezed for removable
Pressure version, initial makeup location is that α (connects to ensure that walnut realizes that 90 ° of-α of self-locking event are less than after falling into apart from the drift angle of vertical direction
Touch the angle of friction of material), the plates of B II are fixed press plate, and distance of the bottom hinge junction C points of B I away from B II is a, the big rootlet of a
Minimum diameter according to walnut determines that a is less than or equal to minimum diameter.
Cam promotion B I first makes its β that rotates a certain angle reach part as dashed when mechanism starts working.Now B
Each length T on I plateiCan all pass by one section of arc length of very little to corresponding point, it is contemplated that the angle of the deflections of B I is minimum,
Therefore herein using go the principle of curved cut-off the camber line passed by it is approximate see the L that is in linei.Obtained by formula (1):
Li=TiTan β formulas (1);
So length T different on the plates of B IiThe different rectilinear path L of correspondencei, obtained by formula (1):

Slide, with the slip of blanking baffle plate I -2, blanking baffle plate I -2 periodically overlaps with the circular hole of the bottom of storage bin hopper I -1, every time
Feeding is once during coincidence.
Walnut enters into the self-positioning pre-breaking shell device of vee-block, vee-block after the blanking port of the bottom of storage bin hopper I -1 falls
Blanking vee-block II -6 and the extruding separate placement of vee-block II -7 in self-positioning pre-breaking shell device, extruding vee-block II -7 cut with scissors
Under, upper, the two intermediate gaps is in " V-shaped " while blanking cam II -9, extruding convex for the jointed shaft of blanking vee-block II -6 for spindle
Wheel II -8 is respectively positioned on rest stage, waits walnut feeding.Due to walnut diameter itself and the angle difference that drops, walnut falls certainly
Extrusion position where in " V-shaped " space that material mouth is fallen into the self-positioning pre-breaking shell device of vee-block would also vary from, specifically
The slightly larger walnut of diameter is shown as in the upper position in " V-shaped " space, the slightly smaller walnut of diameter in " V-shaped " space on the lower
Position, is so achieved that the purpose of " self-positioning ", it is ensured that walnut shell is brought into close contact with the pressurizing unit moment.Walnut enters " V
Behind font " space, blanking cam II -9 is located at remote area of stopping, and extruding cam II -8 enters the rise stage, promotes extruding vee-block

Reach the purpose of " benevolence is not hindered in broken shell ".After the extruding rise of cam II -8 terminates, extruding vee-block II -7 reaches maximum and closes up distance,
Now enter remote area of stopping, the broken shell stage terminates.Further, since being received in extruding cam II -8 rise motion short time in broken shell stage
Power situation is changed greatly, so that each extruding cam and the former 5 degree of relative misalignment, uneven with the energy for reducing mass motion
Weighing apparatus property.To improve rigidity of structure during motion, camshaft by rotating shaft support frame I II -18 and shaft support frame II II -19 with
Rigid support I II -15 and rigid support II II -16 and then mutually fixed with frame.After the extrusion cracking stage terminates, cam is extruded
II -8 enters remote rest stage, and blanking cam II -9 enters backhaul stage, under the traction of spring II -12, blanking vee-block II -6
Open, the walnut for tentatively cracking falls, complete pre-breaking shell process.
Cracked by walnut surface after preliminary pre-breaking shell, because walnut shell is spheroidal structure, quality is hard in addition
And it is crisp, therefore need to consume substantial amounts of energy when preliminary broken, but due to the presence of crackle so that walnut shell is further being crushed
The energy of Shi Suoxu is substantially reduced.
After the self-positioning pre-breaking shell device of vee-block carries out pre-breaking shell to walnut, the walnut that surface cracks falls into collection
Material skewed slot, with backplate, centre is slope for the skewed slot both sides that gather materials, and in the dustpan-shaped of strip, squeezes out the walnut of crackle from upper
And under fall into collection device, be slipped to side along slope, fall plectonemic spiral roller from the charging for being classified flexible hulling machine
In mouthful, second-time breakage is carried out.
Plectonemic spiral roller from the critical component for being classified flexible hulling machine be king bolt roller III -1 and minor spiral roller III -2,
The two axis misalignment certain angle, spiral roller surface is provided with the thread groove suitable with walnut diameter, and thread rotary orientation is identical and in the same direction
Rotate.The present apparatus has different broken shell effects for different design parameters, and specific theory analysis has been given by, herein no longer
Repeat, illustrate specific work process by taking a kind of embodiment as an example below.
The walnut cracked by pre-breaking shell falls propellers side, in propellers motion process, walnut stress and
Spiral broken shell mechanism is as follows:
Below spiral broken shell principle is analyzed from mathematical theory calculating:
Consider from manufacturing cost and single unit system volume size first, two sizes of propellers are determined, due to two spirals
Roller steering is identical, then upward one of the active force one to walnut is downward, according to it was verified that only downward active force is bigger than normal
Can just make walnut be easier to enter broken shell, thus propellers must small one and large one wire speed difference and king bolt roller to the work of walnut
It is firmly downward.In order to easy to assembly, king bolt roller is all as the length of minor spiral rollerThe radius of king bolt roller isTurn
Speed is n1, the radius of minor spiral roller isRotating speed is n2, the equal vulcanie of material of two propellers, the flexible broken shell of realization
Ensure service life simultaneously.
It can be seen from principle according to spiral broken shell, walnut only fall completely within helical groove could realize by walnut shell squeeze it is broken and
Do not interfere with walnut kernel, thus design helical groove when must assure that propellers rotate when both the groove moment engagement.In order to
Walnut shell-breaking efficiency is improved, only increases the quantity of mesh groove, therefore the head number N of helical groove need to be increased, if head number mistake
Many, helical groove wall thickness can be too small, causes insufficient strength, so needs find an optimal value of number N, both ensure that shell-breaking efficiency
Wall thickness intensity is met again.Single propellers are analyzed as follows:
The helical angle of helical groove is α, and pitch is ρ, and helical pitch is K, radius be R wherein:
Tan α=NK/2 π r formulas (5);
The condition of two helicla flute moment engagement:
Known by formula (5) and formula (6), if propellers radius determines, helical angle is only relevant with pitch;By formula (7) and formula (8)
Understand, two propellers helical pitches must equally, while ensureing that specific lobe is the inverse ratio of rotating speed.
As shown in figure 12, the first embodiment:
Spiral roller diameter is identical in this scheme, and rotating speed is identical, and pitch is different but head number is identical, and helical pitch is understood by formula (6)
Difference, does not meet meshing condition, by the sketch of computer simulation it can also be seen that helicla flute does not have at a fully engaged, and linear velocity also phase
With without linear differential, broken shell effect is least preferable.
As shown in figure 13, second embodiment:
Two spiral roller diameters are identical in this scheme, and rotating speed is identical, and pitch is identical, and head number is also identical, from formula (6), lead
Journey is the same, also meets meshing condition, but the linear velocity of propellers is identical, does not have linear differential, is also drawn according to experiment effect
Broken shell effect is undesirable.
As shown in figure 14, the third embodiment:
Two spiral roller diameters are different in this scheme, and rotating speed is different, and pitch is different but head number is identical, from formula (6), leads
Cheng Butong, does not meet meshing condition, and this scheme can not clearly meet helical groove moment meshing condition, and shell-breaking efficiency is low.
As shown in figure 15, the 4th kind of embodiment:
This scheme spiral roller diameter is different, and rotating speed is identical, and wire speed is poor;Pitch is identical and head number is the same, according to formula
(6) understand to meet helical groove meshing condition, also demonstrate that this scheme works is most preferable according to practice result.
The special scheme of also a kind of comparing:
This scheme is the scheme drawn according to theoretical calculation formula, can according to design requirement, change propellers diameter,
Pitch, head number or rotating speed, so as to ensure also realize the function of propellers in other cases.
Walnut shell size is broadly divided into three path lengths:Major diameter dIt is long, central diameter dIn, minor axis dIt is short, remainder almost spherical, reason
Want to think that the gap between walnut shell and benevolence is equidistantly λ.Propellers groove is being fallen into according to lot of experiment validation major part walnut
When, major diameter is axially in parallel with helical axis, and minor axis two ends contact with two propellers grooves.In order to be able to reach preferable broken shell effect,
Groove axial length ψ need to be slightly larger than walnut major diameter dIt is long, radical length φ can install gap τ and change according to propellers, in order to protect
Card broken shell dynamics, needs to meet:
dIt is short-2λ≤2×φ+τ≤dIt is short(formula 9)
This does not hurt walnut kernel while ensuring that broken shell.
As shown in figure 16, when walnut falls in the middle of two propellers, walnut can be subject to three power in the presence of groove profile
Effect, is respectively axial force Fa, shearing force Fs, radial load Fd.Wherein axial force is risen from grading:Walnut bigger than normal is due to axle
Acted on to power, walnut can always prolong axial advancement, and two shaft clearances are increasing, until the size of groove profile is close with walnut, walnut
Into helicla flute;Shearing force plays broken shell with radial load:It is rightabout up and down by big pony roll after walnut enters helicla flute
Shearing force and radial compression power are acted on, shell breakage.
Next the groove profile of helical groove is analyzed, different groove profiles can produce different effects in broken shell to walnut shell
Power, suitable groove profile can produce more preferable broken shell effect.
The first groove profile:V-type groove, due to the self-positioning feature of V-groove, the contact between walnut and V-type groove is a little
Contact.Therefore, V-type groove is concentrated on four points to the power of walnut.Power at walnut stress suffered by unit area is very big, energy
Amount is concentrated on four points of whole walnut.Thus it is easily caused that only walnut shell rupture is imperfect and is damaged to walnut kernel,
And V-groove easily will just be squeezed broken walnut shell and be stuck in groove, influence the broken shell process of other walnuts.Therefore this V-type groove
Design is unreasonable.
Force analysis figure is as shown in figure 17:
Walnut is by two counter-force F of diagram roller contact point3、F4, the also counter-force F of roller1、F2, given by roller
Tangential force F vertically upward7、F8, the downward tangential force F given by another roller5、F6。
Second groove profile:Trapezoidal groove, dovetail groove remains the self-positioning feature of V-groove, between walnut and trapezoidal groove
Contact be still contact.Therefore trapezoidal groove is concentrated on four points to the power of walnut, unit area institute at walnut stress
The power received is very big, and energy is concentrated on four points.Walnut shell crushes incomplete problem and is not resolved.Due to trapezoidal recessed
Narrow portion of the groove without V-type groove, it is to avoid walnut shell is stuck in the problem in groove.But stress is still contacted for point, is received
The problem that power is concentrated, energy is concentrated is not solved also, there is certain defect.Therefore trapezoidal groove is still unreasonable.
Force analysis figure is as shown in figure 18:
Walnut is by two counter-force F of diagram roller contact point3、F4, the also counter-force F of roller1、F2, given by roller
Tangential force F vertically upward7、F8, the downward tangential force F given by another roller5、F6。
The third groove profile:Arc groove, is in itself a class ellipsoid due to walnut, so between walnut and arc groove
Can be in linear contact lay, stress is more uniform compared to point contact.The problem of energy concentration is avoided, makes that walnut shell is broken more to be added
Entirely, and walnut shell is difficult to be stuck in groove.Therefore this arc groove is a kind of the recessed of more satisfactory walnut shell-breaking extruding
Groove type.
Force analysis figure is as shown in figure 19:
Walnut is in linear contact lay with arc groove, so its stress is not single concentrated force, but distributed force.
In arc groove, by four kinds of distributed forces, a kind of be the upward shearing force produced by illustrative helicon roller to walnut
q7、q8, a kind of is the downward shearing force q produced by another propellers5、q6.Also two propellers are respectively to the distribution of walnut
Extruding force q1、q2、q3、q4。
Propellers groove groove profile be not actually only these three, such as it is also parabola shaped, or the equation of higher degree is bent
It is linear, but according to we experimental results demonstrate, only groove profile close to walnut shell shape could improve broken shell rate of perfect kernel and
Efficiency, but the shape of walnut shell is not changeless, so we can only select close with most of walnut shell
Circular arc is used as optimal case.
By plectonemic spiral roller from after being classified the further broken shell of flexible hulling machine, the shell benevolence mixture for obtaining falls into pressure
In roller friction belt separator, because walnut shell has sharp corner angle, and walnut kernel surface is more smooth, therefore the two is same soft
Coefficient of friction on property material must be differed.Friction belt IV -1 when moving up due to the presence of frictional force, the two can by
Moved up in the presence of frictional force.Make shell benevolence in vibrations sleeve I IV -2 and the vibrations drive of sleeve II IV -12 friction belt IV -1
While mixture is moved up, due to the presence of feather key, the end of vibrations sleeve I IV -2 and vibrations sleeve II IV -12 both sides
Face alternately promotes two vibrations sleeves to horizontally slip, and specific motion state is friction belt IV -1 constantly left while transmission upwards
Right swing.Shell benevolence mixture thereon also follows its continuous side-to-side vibrations.Due to the difference of frictional force, walnut shell is brought to
Side, walnut kernel is slipped to lower section because frictional force is smaller naturally, and the two each enters collecting bin, reaches the purpose of separation of hull from kernel.
It is not new to this practicality although above-mentioned be described with reference to accompanying drawing to specific embodiment of the present utility model
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Various modifications or deform still in protection model of the present utility model that field technique personnel make by need not paying creative work
Within enclosing.
