Problems solved by technology

However, in the practice of production and use, it is found that the straw cleaning wheel with this structure has insufficient lateral throwing force on the residual straw on the surface, and there are technical problems such as small straw lateral movement distance, low straw cleaning rate, and poor quality of straw cleaning, and the operation depth is unstable. Adapt to and meet the quality requirements of no-tillage precision seeding operations for seedbed strips

Abstract

The invention discloses a bionic shifting finger type elastic side-throwing straw cleaning wheel, and belongs to agricultural machinery. The bionic shifting finger type elastic side-throwing straw cleaning wheel is characterized in that a radial plate is fixedly installed on the outer part of a bearing base with a bearing through a fastener set A, N poking finger cylinder bases are evenly distributed and fixedly installed on the same side face of the radial plate in the circumferential direction, straw cleaning poking finger welding parts are installed on the poking finger cylinder bases through pin shafts, fastener sets B with the number equal to that of the poking finger cylinder bases are evenly distributed and inserted in the radial plate in the circumferential direction, the fastener sets B are inserted into through holes in the inner side parts of the corresponding straw cleaning poking finger welding parts at intervals, pressure springs sleeve the fastener sets B in a matched mode, and an anti-skid depth limiting circular ring is fixedly and coaxially arranged on the other side face of the radial plate through a screw and a bearing base. The bionic shifting finger type elastic side-throwing straw cleaning wheel is novel, unique and reasonable in structure, good in straw cleaning effect, high in efficiency, good in strip seedbed quality, reliable in use and few in fault.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operating part assembled on a no-tillage planter for cleaning straw. Background technique [0002] The straw cleaning wheel is an operating part used to remove the residual straw covering the field surface to obtain a clean sowing belt on the land surface and provide good seedbed conditions for the sowing operation of the no-tillage seeder. It plays a vital role in ensuring and improving the quality and efficiency of no-tillage seeding operations. Existing straw cleaning wheels are rigid integral wheel discs punched by sheet metal or metal melting and casting, and openings are evenly distributed at the circumference of the wheel disc. During operation, the gap of the straw clearing wheel is inserted into the residual straw and soil on the surface. During the overall movement, the resistance of the soil and straw makes it rotate passively. The straw clearing wheel pushes the resi...
