34,33 lower section of quantitative disk is equipped with the feed opening 43 cooperated with the dosing hole 34 far from 4 side of seed-box;The pine
The piling wheel 32 engaged with the quantitative disk 33 is equipped between soil wheel 2 and the seed-box 4, the piling wheel 32 passes through connecting rod
31 drive piling heads 3 move up and down in the car body 1;The soil-loosening wheel 2 is driven by linkage between the piling wheel 32
The rotation of having a rest property.
Specifically, the linkage includes the first connecting rod 25 that rotation is connected in the car body 1, the first connecting rod
25 one end are hinged with the second connecting rod 24 being slidably connected in the car body 1, and the soil-loosening wheel 2 is coaxially linked with and described second
The cam 21 that connecting rod 24 cooperates;The soil-loosening wheel 2, which deviates, is hinged with drive rod 23 at shaft, and described 23 one end of drive rod is fixed with
With the intermittent rack gears 26 engage of the piling wheel 32, slidably connect on the rack gear 26 with the first connecting rod 25 hingedly
Limited block 27.
It is connect specifically, the cam 21 is worked in coordination with the second connecting rod 24 by magnetic attraction.
Specifically, 1 bottom of car body is respectively equipped with front-wheel 5 and rear-wheel 53, the front-wheel 5 is coaxially linked with side engagement
There is the driving wheel 51 of driving wheel 52, the driven wheel 22 engaged with the driving wheel 52 is coaxially linked on the soil-loosening wheel 2.
Specifically, the front-wheel 5 is rotated by motor driven, the driving wheel mobile as the car body 1.
Specifically, 4 bottom of seed-box is hinged close to 2 side of soil-loosening wheel and the car body 1, the seed-box 4
It can be tilted under the action of first connecting rod 25 connected to it;It is equipped with horizontal plane in the seed-box 4 into the upper of b angle
Inclined plate 44 and declined board 46, wherein 90 °<b<180°;It is equipped between the inclined board 44 and the declined board 46 in parallel
Quantifying board 45, the inclined board 44, the quantifying board 45 and the declined board 46 form one in the seed-box 4 for one
The "U" shaped channel that quantitative seed passes through;After the seed-box 4 tilts, the outlet in the "U" shaped channel is located at described oblique
The lowest point of plate 46.
Specifically, the quantifying board 45 can stretch under the control of atmospheric pressure pole 48, seed in the "U" shaped channel is controlled
Passable quantity.
Specifically, being fixed with the slope 47 with the dosing hole 34 cooperation at 4 outlet at bottom of seed-box.
Water tank 41 is equipped at the feed opening 43 specifically, corresponding to above the quantitative disk 33,41 bottom of water tank goes out
Mouth cooperates with the dosing hole 34.
Specifically, being equipped with fertilizer box 42 below the seed-box 4, it is equipped in the fertilizer box 42 same with the quantitative disk 33
The fertilizer tray 35 of axis connection;The 35 across structure of fertilizer tray, a part is in the fertilizer box 42, and a part is described
At feed opening 43;The fertilizer box 42 outlet cooperates with the fertilizer tray 35, makes the fertilizer tray 35 can be described in intermittent closure
Fertilizer box 42.
Specifically, being equipped with earthing portion 11, the earthing portion 11 and ground close to 4 side of seed-box on the car body 1
The depth of contact is less than the depth capacity of the piling head 3 with ground face contact.
Specifically, being additionally provided with handle 12 on the car body 1.
When work, under the action of manpower or motor, front-wheel 5 rotates car body 1, and band motor vehicles bodies 1 advance.Front-wheel 5 drives together
The driving wheel 51 of axis rotates, and drives the soil-loosening wheel 2 coaxial with driven wheel 22 to rotate by driving wheel 52, soil-loosening wheel 2 connects with ground
Touching, carries out work of loosening the soil.When soil-loosening wheel 2 rotates, cam 21 makes second connecting rod 24 do linear reciprocating motion, drives first connecting rod 25
Rotation controls rack gear 26 and piling 32 periodic contacts of wheel by limited block 27.Meanwhile soil-loosening wheel 2 makes tooth by drive rod 23
The corresponding piling wheel 32 of item 26 has tangential linear motion.In a cycle that rack gear 26 is engaged with piling wheel 32,32 rotation of piling wheel
It circles, drives piling head 3 to extrude a hole on the soil after soil-loosening wheel 2 loosens the soil by connecting rod 31.
The distance between inclined board 44 and quantifying board 45 are slightly larger than the diameter of a seed in seed-box 4, in the work of gravity
Under, seed is deposited between quantifying board 45 and declined board 46, by adjusting the interval distance of quantifying board 45 and 4 inner wall of seed-box
From the quantity of the controllable seed being deposited between quantifying board 45 and declined board 46.When first connecting rod 25 rotates, seed-box is driven
4 inclinations, inclined plate 46 is not mobile still further below for the seed between inclined board 44 and quantifying board 45, between quantifying board 45 and declined board 46
Seed is rolled at 4 outlet at bottom of seed-box by declined board 46, is moved in dosing hole 34 under the action of slope 47.Accurate control
Make the quantity of the seed fallen every time.
Piling wheel 32 drives quantitative disk 33 to rotate, and will rotate from seed-box 4 to feed opening with seed-bearing dosing hole 34
43, water tank 41 is connected to feed opening 43 at this time, and the seed in dosing hole 34 is rushed at feed opening 43 by the water in water tank 41.Quantitative disk
Fertilizer tray 35 is driven to rotate when 33 rotation, one layer of fertilizer in fertilizer box 42 is released fertilizer box 42 by fertilizer tray 35.Before car body 1
Into in the process, the hole extruded before 43 face piling head 3 of feed opening at this time, fertilizer is fallen into hole, and water flow is by dosing hole 34 kinds
Son sweeps away the fertilizer having in also flushable fertilizer tray 35 when coming, and falls into hole together.
Earthing portion 11 scoops up soil when car body 1 advances, and covers and be layed onto being staked on the hole that first 3 extrude of having sowed.
The soil that earthing portion 11 scoops up is shallower, will not destroy seed.It is achievable to loosen the soil, load mould, broadcast during car body 1 is continuously advanced
Kind is watered, a series of streamlineds operation of fertilising and earthing, also can control each position while guaranteeing that seed spacing is identical
The seed amount sowed.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
Improvement is both fallen in the range of claimed invention.
