A straw returning treatment device

Abstract

The invention discloses a treatment device for straw returning to the field, which comprises a frame, a support wheel set that drives the frame to move, and a crushing mechanism installed on the frame. The crushing mechanism includes a casing and a crushing mechanism rotatably installed in the casing. The inner wall of the shell and the ring surface of the crushing roller are processed with crushing teeth that cooperate with each other. The shell is processed with a feed hopper and a discharge pipe. A bracket is provided between the feed hopper and the shell. A guillotine mechanism for cutting straw is installed, and a compensation roller floatingly connected with the crushing roller is installed in the shell below the guillotine mechanism. The crushing roller under the discharge pipe is equipped with a winnowing piece that drives the straw to be thrown out. The crushing mechanism The frame on one side is provided with a transmission mechanism that drives the crushing roller to rotate. In the present invention, by setting the guillotine mechanism and the compensating roller, the straw can be cut and then sent to the crushing roller, so as to increase the crushed grain size of the straw, which is used for returning the straw to the field in hilly areas.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a straw returning treatment device. Background technique [0002] Straw returning to the field is a measure of fertilizing soil fertility and increasing production that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. However, with the rapid popularization of straw returning to the field. When the straw is returned to the field, the crushed straw covers the surface of the farmland, and the covered straw will cause great resistance to the rotary tiller when the land is replanted, and the straw will also cause the soil to be elevated after the straw is returned to the field, causing air leakage in the soil , eventually leading to the problem of seedling death and seedling weakness. The existing processing method is to increase the particle size of the crushed straw, and the ...

AI Technical Summary

Problems solved by technology

When the straw is returned to the field, the crushed straw covers the surface of the farmland, and the covered straw will cause great resistance to the rotary tiller when the land is replanted, and the straw will also cause the soil to be elevated after the straw is returned to the field, causing air leakage in the soil , eventually leading to the problem of seedling death and seedling weakness

The existing processing method is to increase the particle size of the crushed straw, and the common solution is to increase the speed of the crushing roller, but the existing speed increase of the crushing roller requires the use of a transmission mechanism with a faster speed, and the transmission mechanism with a faster speed has a larger volume , so it is only suitable for large-scale planting in plain areas, and for hilly areas, new solutions are needed to deal with the problems caused by straw returning to the field
