Device for cutting and crushing wheat straw

Abstract

A wheat straw cutting and crushing device, comprising a main body, a feeding port is provided on the top of the main body, a grid plate is provided at the bottom of the feeding port, several square through holes are provided in the cutting board, and cutting blades are provided on the left and right inner walls of the through holes A bow-shaped rod is rotatably installed between the first shaft support and the second shaft support, and two limit rings are fixedly installed in the middle of the bow-shaped rod. A movable sleeve is installed on the bow-shaped rod in a rotating manner, and a connection is fixedly installed at the left end of the movable sleeve A connecting block is fixedly installed on the right end of the cutting plate, the connecting rod is hinged on the connecting block through a hinge shaft, a crushing shaft is arranged horizontally in the body, and a rotating blade is evenly arranged on the outer surface of the crushing shaft; the present invention can reciprocate left and right The moving cutting blade performs a preliminary cutting and truncating treatment on the wheat straw, which prevents the rotating blade from being stuck due to the excessive length of the wheat straw, and improves the work efficiency; the wheat straw is cut and broken after the second time, and the crushing effect is good.

Description

Technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a wheat straw cutting and crushing device. Background technique [0002] Wheat straw has been the main fuel used in people’s daily life since ancient times. It has also been used to feed livestock and make fertilizers. However, with the development of society and the improvement of people’s living standards, the energy structure of rural life has changed, and the amount of wheat straw has been drastically reduced. The extensive use of chemical fertilizers has reduced the rate of returning straw to the field to a certain extent. This traditional way of using wheat straw has been gradually abandoned by people. Modern scientific methods and awareness of using wheat straw have not yet been established, resulting in a large amount of surplus of crop straw. It directly leads to open burning of straw, which is widely used. In addition to returning to the field for fertility, i...

Problems solved by technology

[0003] Before the wheat straw is reused, it needs to be cut and crushed to make it into small particles, which is convenient for subsequent further processing and reuse; the traditional way of cutting and crushing the wheat straw is to directly insert the straw as a whole into a machine with a cutting blade. Cutting and crushing in the equipment, due to the long length of wheat straw, it is easy to cause the cutting mechanism in the equipment to be stuck, resulting in unsatisfactory cutting effect of wheat straw, affecting the efficiency of wheat straw cutting and crushing
