A pulverizer with multi-stage pulverization function

Abstract

The invention relates to a pulverizer with a multi-stage pulverizing function, and belongs to the technical field of agricultural machinery. The pulverizer comprises a frame, a primary pulverizing device and a secondary pulverizing device, wherein the primary pulverizing device is mounted on one side of the frame; the secondary pulverizing device is mounted on the other side of the frame; and the primary pulverizing device is communicated with the secondary pulverizing device through a communicating pipe. The pulverizer is simple in structure, and low in to-be-pulverized material selectivity, and primarily pulverized materials can meet the requirements of plate manufacturing and commercial crop planting. The problems that for the structure reason of a conventional pulverizer, the primarily pulverized material granularity is too high, the working efficiency is lower, the production cost and the manual cost are too high, the to-be-pulverized material selectivity is higher, and materials with certain toughness and softness are prone to wind around a transmission shaft are solved. The pulverizer has positive promoting significance.

Description

technical field [0001] The invention relates to a pulverizer with multistage pulverization function, which belongs to the technical field of agricultural machinery. Background technique [0002] 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 required 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 pulverizer, its function is single, and its selectivity to pulverized materials is relatively large, and it is easy to pulveri...

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

However, for trunks and branches with relative density and diameter, it is impossible to achieve thorough crushing.
