Double-wheel-disc-type potato miss-seeding reseeding seeder

Abstract

The invention relates to an integrated seeding part which is assembled on a potato planter, has a miss-seeding reseeding function and can achieve seed separating, seed clearing and seed sowing, in particular to a double-wheel-disc-type potato miss-seeding reseeding seeder, and belongs to the technical field of agricultural machinery. The double-wheel-disc-type potato miss-seeding reseeding seeder comprises a wheel disc installing frame, a seeding wheel disc and a reseeding wheel disc are installed in the wheel disc installing frame in parallel, a reseeding rotation door is hinged to the lower portion of the reseeding wheel disc, a potato seed supplementing box is fixed on the upper portion of the wheel disc installing frame, a push-pull electromagnet is fixed in the potato seed supplementing box, a push-pull rod of the push-pull electromagnet is connected with a reseeding push-pull plate in a hinged mode, the reseeding push-pull plate corresponds to an upper reseeding port formed in the reseeding wheel disc, and a lower reseeding port of the reseeding wheel disc corresponds to a reseeding port seal plate arranged at the bottom of the reseeding rotation door. The double-wheel-disc-type potato miss-seeding reseeding seeder is simple in structure and convenient to install, can achieve precise seed separating, flexible seed clearing and seed protecting, can achieve self-driving, achieves miss-seeding seed supplementing by pulling the electromagnet, achieves miss-seeding reseeding through mechanical button driving and can well adapt to high-speed operation and the precise seeding requirements of the potato planter.

Description

technical field [0001] The invention relates to an integrated sowing component assembled on a potato planter, which has the function of missed sowing and reseeding, and can realize sorting, clearing and sowing. In particular, it relates to a double-disk type potato reseeding seeder for missed sowing, which belongs to agriculture field of mechanical technology. Background technique [0002] With the implementation of the potato staple food strategy in my country, the potato planting area is gradually expanding, and the potato planting machinery is developing rapidly in the direction of large-scale and high-speed. During the operation of the most widely used spoon-chain potato planting machinery at present, when there are situations such as lack of seeds in the seed box, failure to pick seeds from the seed spoon, or more seeds, it will cause missed or re-seeded potato planters, especially large-scale potato planters. When the wide-row planter operates at high speed, it will c...

AI Technical Summary

Problems solved by technology

During the operation of the most widely used spoon-chain potato planting machinery at present, when there are situations such as lack of seeds in the seed box, failure to pick seeds from the seed spoon, or more seeds, it will cause missed or re-seeded potato planters, especially large-scale potato planters. When the wide-row planter operates at high speed, it will cause a large area of ​​missed seeding, resulting in reduced production and land waste

The missed seeding rate of the spoon chain potato planter is above 7%. Now, the improved structure of the potato planter or the structure of the seed meter is usually used to reduce the missed seeding rate, or the hydraulic reseeding system controlled by a single chip microcomputer, stepping motor, etc. To achieve missing broadcast compensation, but the above methods have problems such as complex structure, low reliability, and low applicability
