Profiling claw type floating stubble, grass cleaning mechanism

Abstract

The invention relates to a row cleaner for agricultural no-tillage planting machinery, especially to a biomimetic claw type floating stubble and grass clearing mechanism. The invention is intended to resolve the problems of effect on normal seeding operation and seeding quality or the like because of the winding, accumulation and clog on a colter by a mass of stalks and weeds coated on the protective cropland surface. The floating row cleaner mainly comprises a pair of finger-shaped grass-poking wheels connected with the ground, an installation rack for convergent arms, a cam for regulating depth and a lower limiting arm, wherein the finger-shaped grass-poking wheels are key parts. The pair of finger-shaped grass-poking wheels forming splay with each other is mounted on installation rack for convergent arms, wherein the centers of the pair of finger-shaped grass-poking wheels of the front ends converge at a point and are not interfered with each other. The middle of each finger-shaped grass-poking wheel is provided with a round disk whose circumference is distributed with a plurality of finger-shaped teeth uniformly. The plurality of teeth are radially distributed, line parts of the finger-shaped teeth form a certain angle with the radial line in radial direction of the round disk, and extend to the outer circle from arc.

Description

technical field

[0001] The invention relates to a ridge cleaner on an agricultural tillage machine, in particular to a floating ridge cleaner. Background technique

[0002] No-till sowing is a new agricultural cultivation technique in the conservation tillage developed in recent years. It is directly sown on the uncultivated stubble land covered with straw. The no-tillage surface is covered with residues such as straw and weeds, making it difficult for the seeder to pass through. Traditionally, after plowing and land preparation, the surface is clean, without straw and root stubble that affect the sowing operation, but conservation tillage requires that straw residues be kept as mulch and directly sow on the surface covered by straw residues. Therefore, it is difficult for the seeder to pass through, requiring technology to prevent the blockage of straw residues, otherwise it cannot be carried out normally and smoothly. Whether it can pass through the stubble-covered land ...
