Abstract
The utility model provides a seed stirring device for a circular tube air suction seed sowing device. The seed sowing circular tube is characterized in that a concave groove or a convex ridge is processed on the surface of the seed sowing circular tube, the length directions of the groove and the ridge form an angle of about 30 degrees with the axis of the seed sowing circular tube, and when the seed sowing circular tube rotates, seeds in the seed box can move under the pushing and extruding of the groove and the ridge. The utility model has the advantages that: the seed suction reliability of the circular tube air suction seed sowing device can be improved without adding a special stirring device, the phenomenon of overhead seeds is eliminated, and the seeds can be concentrated to the seed suction holes along with the stirring of the grooves and the ridge belts.
Description
Affiliated technical field
The present invention relates to the seeding unit, particularly circular pipe type aspiration seeding unit of agricultural production with sower.
Background technology
Test shows, the ratio that suction hole is reliably inhaled kind if near the seed the suction hole of aspiration seeding unit remains static is lower, be kept in motion then can significantly improve the ratio of the reliable suction kind of suction hole if near the seed the suction hole can be stirred by certain mechanism.National inventing patent " the dual-purpose circular pipe type air-suction seed-sowing device of the corn wheat " (patent No.: the circular tube air-suction seeding unit that 200410046058.6) is proposed, the smooth surface of seeding pipe in rotary course to the seed in kind of the case without any agitaion, must in kind of case, increase the additional agitating device of a cover and could guarantee reliable inhale kind, thereby otherwise not only suction hole reliably inhale kind of ratio low produce random broadcast leakage and plant seed in the case be easy to make somebody a mere figurehead and cause not having seed and continuous broadcast leakage near the suction hole.
Additional one overlaps agitating device in kind of case, needs the problems such as driving of structure, the installation method in kind of case and the agitating device of solution agitating device, has increased the complexity and the production cost of sower integral body.
Summary of the invention
The present invention proposes the structure that a kind of surface that utilizes the seeding pipe is stirred seed in kind of the case.
Main technical schemes of the present invention is:
A kind of circular tube air-suction seeding unit stir kind of a device, it is characterized by: the both sides at the every capable suction hole in seeding pipe surface are processed with groove or rib band.
Described groove or rib band distribute in the suction hole bilateral symmetry, and have angle with seeding pipe axis.
In concrete operations, the first, the Surface Machining of that section seeding pipe that kind of case width is comprised goes out the groove of depression or the rib band of projection.Be used for the circular tube air-suction seeding unit of small-sized seeds such as wheat can be on the surface of seeding pipe by the groove that mills, method such as plane, mill processes depression.The surface of seeding pipe that is used for the circular tube air-suction seeding unit of large seed such as corn is adopted welding or is pasted the rib band of projection, also can adopt the form of groove and rib band and usefulness to strengthen stirring effect.The second, groove and rib band distribute in the bilateral symmetry of every capable suction hole, if the rib band of projection will note avoiding the rib band to scraping the influence of kind of Unit Installation and work, should make the suction hole both sides respectively keep smooth zone about 10mm.The 3rd, the length direction of groove and rib band and the axis of seeding pipe are the angle about 30 °, and the symmetrical distribution in the suction hole both sides makes the trend that the oriented suction hole of seed is concentrated in the process that groove and rib band stir seed.The 4th, the degree of depth that groove is milled, digs, grinds on seeding pipe surface has two limiting factor (s)s, and one is the wall thickness that gash depth can not surpass the seeding pipe, and another is exactly that groove too deeply can be when work be scraped and taken the pipe surface to planting seed in the case.Seeding pipe rat rib band height also has two limiting factor (s)s, a problem of scraping the band seed, and another is that the too high meeting of rib band makes seed leakage in kind of the case.The 5th, for the ease of processing, can adopt groove connection, parallel with axis for the seeding pipe surface of the circular tube air-suction seeding unit of the less small-sized seed of line-spacings such as wheat.
Beneficial effect of the present invention: need not to increase special agitating device and just can improve the suction kind reliability of circular tube air-suction seeding unit and eliminate the built on stilts phenomenon of seed, and seed can be concentrated to suction hole along with the stirring of groove and rib band.
Description of drawings
Fig. 1 is a seeding pipe Surface Groove or/and the front view of the distributing position of rib band and direction, and arrow is represented the direction of motion.
Fig. 2 is that seeding pipe surface is communicated with, the groove parallel with axis, is suitable for the sower of the little line-spacing crop of wheat one class.
Fig. 3 is seeding pipe radial section figure, has showed two kinds of trench cross section forms, the section form of two kinds of rib bands and the syntagmatic and the position relation of groove and rib band and usefulness, and arrow has been represented the rotation direction of seeding pipe.
Among the figure, seeding pipe 1, groove are or/and rib band 2, and suction hole 3 is planted case (dotted line is represented) 4, seed 5, the V-groove 6 of Milling Process, the arcuate furrow 7 of grinding, the rib band 8 of surface overlaying, the rib band 9 of stickup.
Embodiment
Fig. 1 has shown that seeding pipe 1 Surface Groove of bulky grains such as being used for corn, wide row space sower is or/and the distributing position of rib band 2 and direction.Because the kind case 4 of wide row space crop generally is one of every row, so groove is or/and rib band 2 can cooperate the both sides of the width distribution of kind of case 4 at every capable suction hole 3.
Fig. 2 has shown that seeding pipe 1 Surface Groove of granules such as being used for wheat, little line-spacing sower is or/and the position of rib band 2 and direction.Because the kind case 4 of little line-spacing crop generally all is all-in-one-piece, and two row suction hole spacings are less, are more suitable for adopting groove connection, parallel with axis from machining angle.
Fig. 3 has shown that the employing different processing methods can getable groove and rib band forms.
Claims (2)
- A circular tube air-suction seeding unit stir kind of a device, it is characterized by: the both sides at the every capable suction hole in seeding pipe surface are processed with groove or rib band.
- 2, circular tube air-suction seeding unit according to claim 1 stir kind of a device, it is characterized by: groove or rib band distribute in the suction hole bilateral symmetry, and have angle with seeding pipe axis.
