Description

The zero speed of seed dropping seeding unit

The utility model belongs to a kind of mechanical seeding-apparatus assembly in the agricultural machinery.

In order to realize the agricultural seeder mechanization of operation, the agricultural machinery scientific worker has succeeded in developing multiple mechanical seeding unit both at home and abroad, and it fills not outer four kinds of kind of principles: the one, and outer fill-type promptly is one of this type representative as nest eye Type Seed Metering Device; Outer fill-type seeding unit fills kind of power and only depends on seed gravity, structural limitations in addition, and fill area is less, so the seed wheel linear velocity generally can not surpass 0.35 meter per second; The 2nd, the side fill-type, as vertical disc and centrifugal disc seeding unit, owing to enlarged filling area (can reach more than 300 degree), so kind grain pack completeness and seed wheel linear velocity are increased; The 3rd, spoonful formula fill-type, as vertical bucket wheel formula seeding unit, because little spoon pawl extracting seed is very capable, pack completeness is higher, and the seed wheel linear velocity can reach 0.8 meter per second; The 4th, interior fill-type, the seeding unit of the UNICORN2 beet precision planter of producing as German KLAINE company, fill the centrifugal force that produces when kind of power comes from seed gravity and the rotation of seed drive layer, pack completeness is very high, when the seed plate linear velocity reaches 2.8 meter per seconds, round shaped grain seed pack completeness still can guarantee more than 98%, is a kind of comparatively desirable feed mechanism.But, because the type hole shape of this internal filling type seed plate only can adapt to and the beet seed of the row's of broadcasting pillization, so the scope of application is too narrow; Moreover at seeding time beet kind clothing there is bigger disrepair phenomenon,, also affects seeding quality, more can not adapt to agricultural crops sowings such as soybean, corn and use although beet seed itself be there is no big injury.Outer fill-type, side fill-type and a spoon formula fill out that formula seeding unit operating speed is lower, incompatibility high speed job requirements, and the gram particle problem is more outstanding, and above-mentioned four kinds of principle seeding unit common drawback are can not realize round shaped grain seed zero speed of seed dropping, the qualified index of influence sowing.

The purpose of this utility model designs a kind of zero speed of seed dropping seeding unit exactly, fill-type and spoon formula fill-type principle advantage in this seeding unit is comprehensive, be equipped with novel seeding dish-type pore structure and clear kind mode, make the round shaped grain kind period of the day from 11 p.m. to 1 a.m such as the row of broadcasting soybean and pill beet realize zero speed of seed dropping, and solve gram kind of problem, improve operating speed and operation quality; Simultaneously prolate grain seeds such as corn are adopted that deadweight is clear plants the bunch planting that principle is carried out precise sowing or corn, soybean, enlarge the facility scope of application, improve its generalization degree.

Basic design of the present utility model is, it by housing, seed plate, plant ring, feed shaft, pin, spring and bearing assembling clearly and constitute, the type hole that has several oblique square groove samples in the circumferential edges equal intervals of the seed plate of the row's of broadcasting round shaped grain seed, this type hole plants groove clearly by arc and seed guiding groove is formed, and each two spacings of type hole on the seed plate periphery of facing mutually should be at 0.5～1.5 times of sowing grain in scope; On the circumferential edges of the seed plate that carries out corn Precision Seeding or corn, soybean bunch planting, be uniform-distribution with the combination-type hole of forming by big bellmouth and metered dose hole.

The utility model has been realized the zero speed of seed dropping to the round shaped grain seed, has solved such seeding unit and has broadcast the single and gram subproblem of seeding, the characteristics that have that the seeding operation quality is good, the sub-rate of gram is low, adapt to sowing needs at a high speed, the generalization degree are high.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The zero speed of seed dropping seeding unit is made of housing 1, seed plate 2, clear kind ring 3, feed shaft 4, pin 5, spring 6 and bearing 7 assemblings, and seed plate 2 is the seed-distributing operation part, is again the opposite side housing of zero speed of seed dropping seeding unit.Be the tea tray shape in its profile, be used for soybean, the type hole 8 that has oblique square groove sample of the circumferential edges equal intervals of the seed plate 2 of round shaped grain planting seed such as pill beet, this type hole 8 is by planting groove 9 clearly and help the seed guiding groove 10 of the smooth filling of seed to form for eliminating the gram arc that forms behind the seamed edge of kind pruning, each spacing of two type holes 8 on seed plate 2 peripheries of facing mutually 0.5～1.5 times of sowing in scope; Still be the tea tray shape at its monnolithic case, be used to carry out corn precision metering or corn, the circumferential edges of the seed plate 2 of soybean bunch planting is equidistantly distributing combination-type hole 11, combination-type hole 11 is by assisting kind of the big bellmouth 12 of grain filling and kind of grain being carried out quantitative metered dose hole 13 form, change metered dose hole 13 at axial length dimension, can adapt to corn Precision Seeding or corn, soybean bunch planting needs.

When round shaped grain seed seed plate 2 operations such as use soybean, pill beet; seed plate 2 rotates counterclockwise; when type hole 8 changes filling area [I] over to; slip in the type hole 8 along seed guiding groove 10 by deadweight and centrifugal force by kind of the seed that case stream comes; when type hole 8 changes over to clearly when planting district [II]; clear wedge shaped tip of planting ring 3 pushes away away unnecessary seed is oblique; make and only keep a seed in the type hole 8; seed plate 2 is rotated further; seed after clear the kind in the type hole 8 is covered under the segment protects after planting ring 3 clearly and is protected kind of a district [III]; enter the district [IV] of charging seed, seed is realized zero speed of seed dropping by deadweight and centrifugal force.When prolate grain seed seed plate 2 operations such as use corn, seed plate 2 rotates counterclockwise, when combination-type hole 11 changes filling area [I] over to, fall into the big bellmouth 12 in the type hole 11 of organizing a performance earlier by deadweight and centrifugal force by kind of many seeds that case stream comes, along with being rotated further of seed plate 2, many seeds when seed during refined seeding corn or bunch planting corn, soybean are full of the metered dose hole 13 of combination-type hole 11 again; When the combination-type hole 11 of seed plate 2 changes over to when planting district [II] clearly; seed in the big bellmouth 12 is gone into kind of a heap by the deadweight landing; after quantitative seed enters and protects kind of district [III] in the combination-type hole 11; under the protection of clear kind ring 3, change the district [IV] of charging seed over to; seed mainly falls into soil by deadweight, finishes seeding operation.

The zero speed of seed dropping seeding unit only need be extracted pin 5 when cleaning seed or replacing seed plate 2, just can pull down seed plate 2 easily, and particle is not emitted whole seeds not surplusly.
