Agricultural straw pulverizer

Abstract

The invention discloses an agricultural straw pulverizer. The agricultural straw pulverizer includes a feeding device and a pulverizing device; a preprocessing box is fixedly arranged at the center ofthe top of a box body, and the preprocessing box is communicated with the box body through a feed opening; a shearing arm is fixedly arranged on the inner wall of an inner cavity of the preprocessingbox; a filter net is fixedly arranged on the lower side of the inner cavity of the box body, the upper side of a filter net is provided with a pulverizing chamber, and the lower side of the filter net is provided with a discharge chamber; a discharge hole is formed in the right side of the box body, a motor box is fixedly arranged below the box body, the motor is fixedly arranged at the center ofthe inner cavity of the motor box, and an output shaft of the motor is connected with a pulverizing rotating shaft; a base is fixedly arranged below the motor box, and the lower end face of the baseis fixedly provided with a support device. The support device includes a support column and a foot, the support column is vertically arranged on the lower end face of the base, and the lower portion of the support column is provided with the foot. The agricultural straw pulverizer has the advantages of being simple in structure, convenient to use, thorough in pulverizing and stably supported.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to an agricultural straw crushing device. Background technique [0002] Straw is the main by-product of crops and an important biological resource for industry and agriculture. Crop straw is rich in nutrients and can be used as fertilizer, feed, living fuel and raw materials for industrial and sideline production, etc., referred to as "four materials"; at present, my country is vigorously promoting The pollution-free utilization technology of crop straws. Among them, the straw pulverizer is a commonly used machine for farmers. It is used for pulverizing corn straw, wheat straw and other crop straws. The pulverized straw is easy to store and degrade naturally. The demand for straw pulverization technology is getting higher and higher. In the existing technology, straw pulverizers for the recovery of soft crop straws such as wheat straw, rice straw and corn straw have...

[0002] Straw is the main by-product of crops and an important biological resource of industry and agriculture. Crop straw is rich in nutrients and can be used as fertilizer, feed, living fuel and raw materials for industrial and sideline production, etc., referred to as "four materials"; currently my country is vigorously promoting The pollution-free utilization technology of crop straws, among which the straw grinder is a machine commonly used by farmers. It is used for crushing crop straws such as corn stalks and wheat straws. The crushed straws are convenient for storage and natural degradation. With the continuous development of agricultural mechanization, people The demand for straw crushing technology is getting higher and higher. In the existing technology, straw crushers for recycling soft crop straws such as wheat straw, rice straw, and corn straw have been widely used, but for hard crops such as cotton straw Straw, because of its hard texture, is not suitable for bundling, but there are very few straw crushers corresponding to it, and the machine crushing is not uniform enough, resulting in poor straw treatment effect; therefore, we need an agricultural straw crushing device
