Extrusion-type straw smashing device

Abstract

The invention discloses an extrusion-type straw smashing device. The device includes a shell, the left side of the shell is communicated with a feeding pipe, the communicated portion between the feeding pipe and the shell is provided with a communicating port, and the portion, at the right side of the communicating port, of the interior of the shell is provided with a cutting box; the right side of the cutting box is communicated with a smashing box. Through multiple groups of extrusion rollers which are arranged gradually close to one another, straw is extruded and conveyed by the extrusion rollers to provide convenience for follow-up cutting and smashing; by arranging cutting wheels and smashing cutters, straw strips are cut in a block shape by the cutting wheels to provide convenience for follow-up smashing, and the smashing efficiency is improved; by arranging an extruding plate to extrude the straw during smashing, the straw can be fully in contact with the smashing cutters, smashing can be achieved more thoroughly, and the smashing effect is improved; by arranging impact beads for beating a screening plate, the screening efficiency is ensured.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to an extrusion type straw crushing device. 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.

Problems solved by technology

[0003] In the straw processing process, a crushing device is required. The traditional crushing device has a simple structure, and the straw is crushed by a crushing roller. Inside the crushing device, the straw is relatively fluffy, resulting in no force point for the crushing knife, resulting in thorough crushing of the straw, and the crushing effect needs to be improved
