High-efficient straw chopping device for agriculture

Abstract

The invention discloses a high-efficiency straw chopping device for agriculture, which comprises a base, on which a left support plate and a right support plate are respectively arranged on the left and right sides; Broken box; the left side wall of the right support plate is rotated to be provided with a first rotating shaft, the first bevel gear is installed on the left end of the first rotating shaft, and the second bevel gear is also installed on the second rotating shaft, and the second bevel gear meshes with the first bevel gear; The left side wall of the right support plate is also provided with a deceleration motor, the deceleration motor is connected with a turntable, the left end of the turntable is connected with a connecting rod through a pin shaft, the bottom end of the connecting rod is hinged with a lifting rod, and the left side of the right support plate is provided with a first limit position. The lifting rod passes through the first limiting sleeve and is connected with a rack, and a gear is also installed on the first rotating shaft, and the gear and the rack are meshed. The shredding box of the present invention works in forward and reverse directions, and the straw will be displaced due to the inertial effect each time when the forward and reverse conversion is performed, so that the orientation of the straw is different each time it is cut, and the cutting effect is improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a high-efficiency straw chopping device for agriculture. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining parts of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops after harvesting 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 and lignin. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. [0003] In order to protect the environment and recycle resources, the country has now banned the burning of straws. It is a good wa...

AI Technical Summary

Problems solved by technology

[0003] In order to protect the environment and recycle resources, the country has banned the burning of straws. It is a good way to crush and reuse straws. However, due to the high content of crude fiber and long length of many straws, it is inconvenient to crush them directly, and it is easy to cause crushing. The blade and shaft are stuck, and the above situation can be avoided by gradually chopping the straw; the chopping efficiency of the ordinary straw chopping device is low, and the cutting effect of the straw is not good, and the cutting is not sufficient, and the cut straw often needs to be further crushed. To achieve the effect of use, resulting in an increase in cost
