Corn straw pulverizer

Abstract

The invention discloses a corn straw pulverizer. The corn straw pulverizer includes a shell and a base; the upper end of the left side face of the shell is provided with a feeding inlet, the feeding inlet is communicated with an inner cavity of the shell, the upper end of the shell is provided with a coupler, the upper end of the coupler is provided with a motor, the lower end of the coupler is provided with a rotating shaft, an output shaft of the motor is connected with the rotating shaft through the coupler, the rotating shaft is provided with two first cross plates parallel up and down, and the portions, located between the two first cross plates, of the left side and right side of the rotating shaft are provided with longitudinal crushing cutters. The corn straw pulverizer is simple in structure and convenient to use, the inside working condition of the corn straw pulverizer can be observed, meanwhile the height of the shell can be adjusted, when the corn straw pulverizer breaks down, a user can conveniently repair the inside of the corn straw pulverizer and can sieve crushed materials, the uniformity of the crushed materials is ensured, the quality of the pulverizer is ensured, movement of the pulverizer can be achieved, and the special production requirement of the user is met.

Description

technical field [0001] The invention relates to the technical field of crushing devices, in particular to a corn stalk crushing device. Background technique [0002] Straw is the general term for the stems, leaves and ears of mature crops, usually referring to wheat, rice, corn, potatoes, rapeseed, cotton, sugar cane and other crops, which are usually the remaining part of coarse grains 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. Straw is also a roughage. Crude fiber content is 30%-40% higher, and contains lignin, etc. Although lignocellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. Straw can be made after crushing Various agricultural by-products are recycled. The existing straw grinder crushes the straw ...

AI Technical Summary

Problems solved by technology

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. Straw is also a roughage. Crude fiber content is 30%-40% higher, and contains lignin, etc. Although lignocellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. Straw can be made after crushing Various agricultural by-products are recycled. The existing straw grinder crushes the straw particles to be relatively large, and the phenomenon of machine jamming easily occurs inside the machine, which affects the crushing efficiency. For example, the patent application publication number 201720122120.8 discloses a corn straw crushing device. However, there are certain defects in the use of the above patents. Firstly, the device cannot be moved, secondly, the crushed materials cannot be screened, and finally, the working conditions inside the machine cannot be observed.
