Long-distance extrusion straw pulverizer for agricultural harvesting

Abstract

The invention discloses a long-distance extrusion straw pulverizer for agricultural harvesting. The long-distance extrusion straw pulverizer for agricultural harvesting comprises an extruding materialbarrel, a conveying material barrel, a feed hopper, a first motor, a discharge pipe, a second motor and an induced draft fan. The extruding material barrel is located above the conveying material barrel. Multiple feeding rollers are horizontally arranged in the feed hopper. Horizontal conical inner containers are fixedly arranged in the extruding material barrel and the conveying material barrelcoaxially. A material hooking rotary stick and a spiral extruding blade are fixedly mounted on a first transmission shaft coaxially, and multiple shearing pieces are evenly distributed on the spiral extruding blade. A spiral conveying blade corresponding to one conical inner container is arranged on a second transmission shaft. By means of the two material barrels with the same structures, the straw extruding contact time is prolonged, straw can be broken, resistance of the straw is reduced, and stable pulverizing of pulverizing rollers is guaranteed. The straw is evenly fed through the feeding rollers in the feed hopper, it is avoided that excessive straw is fed at a time, and the use safety is improved.

Description

Technical field [0001] The invention relates to the field of agriculture, in particular to a long-distance extrusion straw crusher for agricultural harvesting. Background technique [0002] The straw shredder can smash corn stalks, straws, peanut skins, bean stalks, flower wood and other burnable crop waste stalks. The wasteful burning of these crop straws is avoided, the environment is well protected, and renewable energy is effectively developed. The machine has reliable performance, simple and convenient operation. The equipment produces a wide range of raw materials, which can be adapted to burnable crop stalks such as corn stalks, straws, peanut skins, bean stalks, and flower wood. Existing agricultural straw crushing devices often squeeze and crush straws directly through crushing rollers. However, due to the large volume of straws and the high degree of integrity of the straws, the load of the crushing rollers increases. A large amount of straws causes the crushing rolle...

AI Technical Summary

Problems solved by technology

Existing agricultural straw crushing devices often squeeze and crush straws directly through the crushing rollers. However, due to the large size of the straws and the high degree of integrity of the straws, the load on the crushing rollers increases, and a large amount of straw causes the crushing rollers to stop rotating. In severe cases, the drive motor will burn out, which is not conducive to the long-term use of the pulverizer
