Farmland surface cleaning mechanism with bionic curve characteristics

Abstract

The invention provides a farmland shallow ground cleaning mechanism with a bionic curve character, and belongs to the technical field of agricultural machinery. The bottom end of a circular tube in a connection assembly is fixedly connected with the top face of a base in a connection base. A crop poking wheel assembly I is fixedly connected with a circular hole in a hanging lug II in the connection base through a bolt III and a nut I. A crop poking wheel assembly II is fixedly connected with a circular hole in a hanging lug I in the connection base through a bolt IV and a nut IV. The farmland shallow ground cleaning mechanism has the crop cutting, crop poking and crop throwing functions and is capable of cleaning up straws, stubbles and soil blocks in the working region effectively, and stubbles can be thrown to the two sides of a seed bed beneficially through rotating of concave circular discs under the condition of serious stubble coverage; the mechanism can be used for farmlands with the higher soil moisture content, soil blocks attached to the concave circular discs and wheel teeth of the circular discs can be turned and dumped onto the ground easily under the action of gravity, the attachment disengaging function is achieved, and the functions of loosening the soil and reducing the soil hardening are achieved; the working resistance is low, the structure is simple, no extra power is needed, the anti-blocking effect is good, and the cleaning effect of the farmland shallow ground can be improved effectively in the working process of no-tillage planters.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a farmland surface cleaning mechanism with bionic curve characteristics. Background technique [0002] When the no-tillage seeder works on the land under conservation tillage, a large amount of straw and root stubble remaining on the ground seriously affect the quality of sowing, thereby reducing the emergence rate. Therefore, it is of positive significance to improve the operating efficiency of the seeder to clean the seed bed and remove the residual cover on the ground in time. Invention patent (a profiling claw-type floating stubble and grass mechanism CN 101336575) discloses a stubble and grass clearing mechanism for no-tillage seeders, which uses a pair of "eight"-shaped weeding wheels to remove weeds in seedbeds. Shape optimization and parameter improvement can improve stubble cleaning effect. This mechanism has a good cleaning effect on short s...

Problems solved by technology

This mechanism has a good cleaning effect on short stalks and weeds, but when encountering long stalks, the two stubble wheels compete for long stalks, so they can only simply move the long stalks to the furrows instead of dividing them into the furrows. Both sides of the seed bed will affect the seed bed behind the stubble picking mechanism (in front of the opener)
