Straw crushing turnover device

Abstract

The invention belongs to the technical field of straw turnover, in particular to a straw crushing turnover device. The device comprises a rack, a feeding hopper, a conveying plate, a crushing unit anda cutting unit, wherein the feeding hopper is located in the rack, the feeding hopper is located under a feeding port; the conveying plate is located under the feeding hopper, the under a feeding port plate is arranged inclined to the left; the crushing unit is located at the right side of the conveying plate, straw on the conveying plate slides rightward along the conveying plate under the action of gravity and falls into the crushing unit to be crushed, the portion, under the crushing unit, of the rack is provided with a discharging port; the cutting unit is located above the conveying plate, the cutting unit is located at the left side of the crushing unit, and the cutting unit is used for cutting the straw on the conveying plate to reduce the size of the straw entering the crushing unit, thereby improving the crushing efficiency. The straw crushing turnover device improves the crushing efficiency, ensures the smoothness of work and improves the utilization rate of energy.

Description

technical field [0001] The invention belongs to the technical field of straw returning to the field, in particular to a straw crushing and returning device. Background technique [0002] Straw is an important part of rural waste at present. The burning of straw causes a substantial increase in greenhouse gas emissions every year, and a large amount of active ingredients such as cellulose in straw are wasted. With the development of social economy and changes in national policies, agricultural machinery has been vigorously developed. Especially at present, the country promotes the development of large areas of cultivated land through the promotion of farms and cooperative systems, promotes the use of large agricultural machinery, improves agricultural production efficiency, and reduces Resource consumption, improve the recycling rate of straw, and protect the environment. Returning the straw to the field by crushing can effectively increase the organic matter of the soil and...
