High-efficiency cotton straw forage crusher

Abstract

The invention discloses a high-efficiency cotton straw forage crusher and belongs to the technical field of straw processing. The crusher comprises a crushing box, wherein a crushing shaft is mountedin the crushing box, the bottom of the crushing shaft is connected with a gear box, the horizontal position of the gear box is connected with a cutting shaft, and the left end of the cutting shaft penetrates through the crushing box to be connected with a cam; the upper end of the cam is in contact with a rolling ball, the upper end of the rolling ball is connected with a baffle, the upper end ofthe baffle is connected with a lifting shaft, the lifting shaft penetrates through a guide frame arranged at the left end of the crushing box to be connected with a cutting knife, and the cutting knife is arranged in a guide cylinder; the guide cylinder is fixed to the lower end of a feeding cylinder arranged at the upper end of the left side of the crushing box, and a reset spring is arrange on the outer side of the lifting shaft between the baffle and the guide frame. According to the high-efficiency cotton straw forage crusher, straw in the feeding cylinder is crushed and cut into a plurality of pieces, the straw pieces enter the crushing box, blockage of a feeding port is avoided, and the reliable running capability of the high-efficiency cotton straw forage crusher is improved; meanwhile, the straw is crushed in the vertical and horizontal directions through the crushing shaft and the cutting shaft.

Description

technical field [0001] The invention relates to the technical field of straw processing, in particular to a cotton straw high-efficiency forage grinder. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. 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] my country is a large agricultural country, the total amount of straw ...

Problems solved by technology

[0006] Chinese patent (notification number: CN207981054U) discloses an integrated animal husbandry straw feed crushing and mixing processing device, including a processing box and a fermentation storage box. Support columns are symmetrically arranged on both sides of the lower end of the processing box, and the lower end of the support column is connected with the fermentation storage box. The box is connected and fixed, and the lower end of the fermentation storage box is symmetrically provided with outriggers on both sides, and the lower end of the outriggers is provided with rollers for easy handling of the device. However, in actual operation, the straw is directly put into the processing device without any treatment, and it is easy to be blocked at the feed inlet, which will seriously affect the later crushing effect. Therefore, further improvement is needed.
