A kind of straw shredder

Abstract

Belonging to the technical field of agricultural machinery, the invention relates to a straw crusher, which is composed of a base, a motor, a material box, a crushing box, a top cover, a drive shaft and a conveying fan. The crushing box is fixed on the base. The motor is fixed on the base at the crushing box end, and the conveying fan is mounted on the base at the crushing box side. The bottom of the crushing box is provided with the material box, which is communicated with the crushing box. The straw crusher has the characteristics of simple structure, small selectivity on crushed materials, multiple functions, and low purchase cost, and the materials crushed in one time can meet the requirements of plate making and commercial crop planting. The problems of oversize granularity of materials crushed in one time, low work efficiency, too high production cost and labor cost, great selectivity on crushed materials, tangling of the drive shaft by materials with certain toughness and softness in existing crusher because of structural reasons can be solved, so that the straw crusher has positive popularization significance.

Description

technical field [0001] The invention relates to a straw pulverizer, which belongs to the technical field of agricultural machinery. Background technique [0002] Crusher is a kind of agricultural machinery widely used in agricultural production, planting, breeding and deep processing of agricultural products. At present, with the development of the panel industry (artificial panel) and the continuous expansion of the planting of economic crops (such as fungi), a large amount of straw particles are needed as the raw material for the panel and the medium for the planting of the fungus. Due to the structure of the existing pulverizer, the particle size of the one-time pulverized material (straw) is too large, which cannot meet the requirements of board making and economic crop planting, and must be pulverized repeatedly, resulting in low work efficiency, low production costs and labor costs. The cost is too high. At the same time, due to the structural reasons of the existing...

AI Technical Summary

Problems solved by technology

Due to the structure of the existing pulverizer, the particle size of the one-time pulverized material (straw) is too large, which cannot meet the requirements of board making and economic crop planting, and must be pulverized repeatedly, resulting in low work efficiency, low production costs and labor costs. cost too high

At the same time, due to the structural reasons of the existing pulverizer, its function is single, and its selectivity to pulverized materials is relatively large, and it is easy to pulverize cotton stalks and corn stalks with large texture; Toughness, softness of wheat straw, rice straw, etc., it is very easy to entangle the transmission shaft

For trunks and branches with relative density and diameter, it is impossible to crush
