Agricultural straw crushing equipment

Abstract

The invention discloses agricultural straw crushing equipment, and relates to the technical field of straw processing. The agricultural straw crushing equipment comprises a box body, wherein a liftinggroove is formed in the right side of the box body; a filter plate is rotationally connected to the position, corresponding to the lifting groove, of the left side of an inner cavity of the box body;a lifting rod is fixedly installed on the right side of the filter plate, and the right end of the lifting rod penetrates through the lifting groove and extends to the right side of the lifting groove; the right end of the lifting rod is rotationally connected with a lifting plate; a first rotating motor is fixedly installed on the right side of the box body; and a rotating rod is fixedly installed on an output shaft of the first rotating motor, and the end, away from the output shaft of the first rotating motor, of the rotating rod is rotationally connected with the right side of the liftingplate. Through the arrangement of the vibrating filter plate, uncrushed raw material and crushed raw material are separated, and are automatically screened after crushing is completed, so that the raw material directly enters a stirring stage, excessive crushing of the crushed raw material is reduced, meanwhile, the raw material conveying step is also reduced, and the overall working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of straw processing, and in particular relates to crushing equipment for agricultural straw. Background technique [0002] Straw, straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content (30%-40%), and contains lignin and so on. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. [0003] The existing straw processing often separates crushing ...

AI Technical Summary

Problems solved by technology

[0003] The existing straw processing often separates crushing and stirring, and transports the crushed raw materials to the stirring device through transportation tools, which reduces work efficiency, easily causes raw material loss, increases the risk of pollution, and is not conducive to improving product quality
