Straw filament rubbing and compacting field returning machine

Abstract

The invention discloses a straw filament rubbing and compacting field returning machine. The straw filament rubbing and compacting field returning machine comprises a shell, a picking and shredding device, a filament rubbing roller, a filament rubbing concave plate, a throwing and raising draught fan, multiple moldboard plows and multiple flow guide pipes; the shell comprises two side plates and multiple transverse beams; the picking and shredding device is installed on the shell; the two ends of the filament rubbing roller are rotatably supported on the two side plates respectively; the two ends of the filament rubbing concave plate are connected to the two side plates respectively; the concave face side of the filament rubbing concave plate faces the filament rubbing roller; the two ends of the throwing and raising draught fan are installed on the two side plates respectively, and a draught fan hood body is arranged at the outer side of the throwing and raising draught fan; the moldboard plows are suspended on the shell through a plow frame; the moldboard plows are equidistantly arranged at one side of the throwing and raising draught fan, and the distances between the moldboard plows and the throwing and raising draught fan are increased in sequence from one end of the draught fan to the other end of the draught fan; the flow guide pipes correspond to the moldboard plows one to one; after straw is shredded by the picking and shredding device, the straw passes through a filament rubbing gap, the draught fan hood body and the flow guide pipes in sequence, then falls into furrows formed by furrowing of the moldboard plows, and is then covered with soil blocks turned over by the adjacent moldboard plows.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering machinery, and in particular relates to a straw rubbing and silking densification returning machine. Background technique [0002] Applying straw to soil can supplement soil organic matter, increase soil microbial activity, enhance soil fertilizer supply capacity, and improve soil structure and physical and chemical properties. Straw returning is not only an irreplaceable main channel for straw utilization, but also a need to increase soil organic matter to protect soil fertility and achieve sustainable agricultural development. The existing modes of straw returning to the field are mostly crushed and then directly turned over and covered with straw, which takes a long time for straw returning to the field to decompose, especially in the alpine region, which has become the main practice of straw returning to the promotion of regional production. obstacle. The existing straw retu...

AI Technical Summary

Problems solved by technology

The existing straw returning machines mainly crush the straw and cover it on the ground surface, or bury it shallowly in the soil. Covering and returning the field can reduce the evaporation of soil water, but the straw decomposes slowly, which is easy to cause disease, and also delays the growth of crops

Shallow burial and returning to the field can easily cause too large soil voids, resulting in poor passability for subsequent sowing operations, and the seeds cannot be in close contact with the soil, affecting seed germination and other problems

Moreover, after the straws distributed on the soil surface decompose, the organic matter mainly exists on the soil surface, which has no obvious effect on the organic matter content of the entire plow layer soil, especially not conducive to the elimination of pests and weeds.
