High-efficient straw chopping device for agriculture

Abstract

The invention discloses a high-efficient straw chopping device for agriculture. The high-efficient straw chopping device for agriculture comprises a pedestal. A left supporting plate and a right supporting plate are arranged on the left and right sides of the pedestal; a second rotating shaft is rotationally arranged on the pedestal; a chopping case is fixed on the top of the second rotating shaft; a first rotating shaft is rotationally arranged on the left side of the right supporting plate; the left end of the first rotating shaft is equipped with a first bevel gear; the second rotating shaft is further provided with a second gear; the second bevel gear is engaged with the first bevel gear; a deceleration motor is arranged on the left side wall of the right supporting plate; a rotary disc is connected to the deceleration motor; a connection rod is rotationally connected to the left end surface of the rotary disc via a pin roll; an elevating rod is hinged to the bottom end of the connection rod; a first spacing sleeve is arranged on the left side of the right supporting plate; the elevating rod passes through the first spacing sleeve to be connected with a rack; a gear is further mounted on the first rotating shaft; and the gear is engaged with the rack. The chopping case can forwardly and backwardly rotate; due to an inertia effect during the forward and backward rotation, the straws are displaced; and therefore directions of the straws are different during each time cutting, so chopping effect can be 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
