Abstract
A kind of helix gradual change precise seeder, making full use of helix gradual change theory, under adopting the condition of the inside and outside tribology principle of seed, according to the method for seed morphology discharge, design is a kind of to be curried with helix gradual change rib on frustum, on guide groove post with on helix gradual change groove and discharge capacity adjustment disk with the multiple spiral Combined screw spin line gradual change precise seeder of leading kind of mouth.During work, guaranteeing under seed not damaged state, by helix gradual change rib, seed is curried, controlled to lead kind of a mouth aperture size by discharge capacity adjustment disk, realize the discharge orderly to seed essence amount simple grain, and under the effect of helix gradual change groove, sequence guiding is carried out to seed, achieve seed interval and flow out sowing port in an orderly manner.Present invention achieves orderly, not damaged, essence amount simple grain seeding mode.
Description
Technical field
The present invention relates to a kind of helix gradual change precise seeder, particularly for the device of agricultural machinery essence amount seeding, belong to agricultural machinery technological field.
Background technology
The quality of agricultural crops batch production essence amount simple grain breeding stability, is the important indicator weighing seeding unit batch production breeding quality, judges the foundation of the performance quality of seeding unit own especially.For solving the problem of batch production breeding reliability, relevant scholar inquires into essence amount single-kernel seed-metering device and develops, design the seeding unit that a series of applicable batch production breeding uses, wherein representative mechanical seed sowing device is as inside and outside fluted-roller feed mechanism, nibs formula seeding unit etc., though good operating stability, reliability are high, but sowing port physical dimension is larger, Seeding Uniformity is poor, amount of seed metering controls not accurate, easy appearance wound is planted and is damaged and plants, and is merely able to carry out the huge discharge of seed and the needs of multi-grain sowing.Another is aspiration, blowing-type metering device, and need before breeding first to carry out seed pelleting, although seedling-damaging rate is low, productivity ratio is higher, easily causes air-hole blockage, and adds the input cost of seed, and Aeroassisted equipment is many, and whole seeding unit price is high.In a word; though above seeding unit has certain advantage; but the defect that self cannot overcome again, all can not realize the task of the essence amount simple grain in simple economy, protection seed and seeding process, the problem run in batch production essence amount simple grain seeding process can not be solved completely.Therefore, simple in the urgent need to a kind of structure, easy to use, the seeding unit of essence amount simple grain seeding can be completed stability and high efficiency.
Summary of the invention
For an above difficult problem, design is a kind of by a kind of helix gradual change precise seeder currying frustum (1), discharge capacity adjustment disk (2), guide groove post (3), sowing port (4), power transmission shaft (5), housing (6) combine.During seeding, first seed is positioned in the cone dish kind box of housing upper end, according to the needs of essence amount simple grain seeding, the rotating speed of adjustment power transmission shaft (5) controls the rotation currying frustum (1), the discharge capacity of seed is controlled again according to the aperture size of how many adjustment discharge capacity adjustment disk (2) of seed sequence quantity, use the differential motion between parts and seed and mutual friction, by the rib that curries of helix gradual change, seed is curried, guaranteeing under the undamaged state of seed through discharge capacity adjustment disk, by leading the orderly discharge of kind of cause for gossip existing seed essence amount simple grain, the outflow sowing port (4) of seed regular intervals is realized under the groove effect of helix gradual change.This device utilizes the theory of helix gradual change, adopt the principle of the inside and outside friction of seed, according to the method for seed morphology discharge, multiple spiral form is used to combine, devise one and curry frustum with helix gradual change rib, helix gradual change groove guide groove post, the helix gradual change precise seeder of discharge capacity adjustment disk, achieves orderly, not damaged, essence amount simple grain seeding mode.There is structure simple, easy to use, the features such as breeding is efficient.
