Abstract
The invention relates to a spiral line gradient type fine-quantity seed sowing device. A spiral line gradient theory is fully utilized, the condition of internal friction and external friction of seeds is adopted, and a multi-spiral combined type spiral line gradient type fine-quantity seed sowing device which is provided with a spiral line gradient edge on a combing and brushing cone, a spiral line gradient groove formed in a guide slot column and a seed guiding hole formed in a sowing quantity regulating plate is formed by using a seed shape arranging method. During operation, under the condition of guaranteeing that seeds are not damaged, the seeds are combed and brushed by virtue of the spiral line gradient edge, the aperture of the seed guiding hole is controlled by the sowing quantity regulating plate, the fine-quantity and ordered single seed sowing is realized, and the order guiding is carried out on the seeds under the action of the spiral gradient groove, so that the effect that the seeds orderly flow out from a seed sowing hole at regular intervals is realized. The spiral line gradient type fine quantity seed sowing device realizes an ordered, no-damage and fine-quantity single seed sowing manner.
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, be the important indicator of weighing seeding unit batch production breeding quality, judges especially the foundation of the performance quality of seeding unit own.For solving the problem of batch production breeding reliability, relevant scholar inquires into and develops essence amount single-kernel seed-metering device, design the seeding unit that a series of applicable batch production breedings are used, wherein representative mechanical seed sowing device is as inside and outside fluted-roller feed mechanism, type cellular type seeding unit etc., though good operating stability, reliability are high, but the sowing port physical dimension is larger, Seeding Uniformity is poor, amount of seed metering is controlled not accurate, be prone to wound and plant and damage and plant, be merely able to carry out the large discharge capacity of seed and the needs of multi-grain sowing.Another is aspiration, air-sweeping type seeding unit, needs first to carry out seed pelleting before breeding, although seedling-damaging rate is low, productivity ratio is higher, easily causes pore to stop up, and has increased the input cost of seed, and Aeroassisted equipment is many, and whole seeding unit price is high.In a word; though it is certain that above seeding unit has advantages of; but the defect that self can't overcome again, all can not realize the task of the essence amount simple grain in simple economy, protection seed and seeding process can not solving the problem run in batch production essence amount simple grain seeding process fully.Therefore, in the urgent need to a kind of simple in structure, easy to use, can complete the seeding unit that essence is measured the simple grain seeding stability and high efficiency.
