A multifunctional pulverizer

Abstract

The invention relates to a multifunctional pulverizer and belongs to the technical field of agricultural machinery. The multifunctional pulverizer comprises a rack, a pulverizing motor, a conveying fan and a driving belt, wherein the driving belt is mounted at one end of the rack through a driving shaft and a driven shaft, a motor is fixedly mounted at the other end of the rack, an upper prepressing breaker roll and a lower prepressing breaker roll are vertically mounted through mounting plates on the rack between the motor and the driving belt, and a pulverizing hob and a fixed pulverizing cutter are mounted at the rear ends of the upper prepressing breaker roll and the lower prepressing breaker roll through the mounting plates; a material throwing device is mounted on the rack below the fixed pulverizing cutter and is communicated with the conveying fan. The multifunctional pulverizer has low selectivity on pulverized materials, the materials pulverized once can meet the requirements of plate making and cash crop planting, the problems that the granularity of the materials pulverized once by a conventional pulverizer is too large, the selectivity of the pulverized materials is higher and a driving shaft gets stuck easily by the materials with certain toughness and softness are solved, and the pulverizer has positive promotion significance.

Description

technical field [0001] The invention relates to a multifunctional 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 th...

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
