Hob-type straw grinding recycling machine

Abstract

The invention relates to the agricultural harvest machinery, belonging to the improvement of straw grinding machinery, in particular to a hob-type straw grinding recycling machine. An input shaft of a gearbox arranged on a casing is connected with an output shaft of a tractor; a pulley on an output transmission shaft of the gearbox drives the pulley on a fan shaft through a belt; the pulley at the other side of the fan shaft drives the pulley on a main shaft of a grinding hob roller through the belt; a chain wheel arranged at the other side of the main shaft of the grinding hob roller drives the chain wheel on a feeding packing auger shaft through a chain; the ends of a fan blade arm are respectively provided with a cutting knife; and aggregate grids evenly distributed and arranged at the lower part of an opening of the casing are fixedly connected on a supporting plate matched with the roller surface of the grinding hob roller. The hob-type straw grinding recycling machine carries out hob-type cutting with supporting on the straw in the farming field, with low stubbles, good grinding effect and smaller power consumption. The hob-type straw grinding recycling machine is connected with the tractor by adopting a rear suspension mode, and has convenient connection, good adaptability to the power transmission of the tractor, convenient and fast transmission power, reliable performance and high work efficiency.

Description

Technical field [0001] The invention relates to an agricultural harvesting machine, which belongs to the improvement of a straw crushing machine, in particular a hob-type straw crushing and recycling machine. Background technique [0002] Straw is the main by-product of crops and an important biological resource for industry and agriculture. At present, the straw of crops can be directly returned to the field as fertilizer or used to make paper, feed, and extract plant fiber. When used as a raw material for papermaking, feed, and plant fiber extraction, straw recycling is required. Most of the existing straw crushing and recycling machines use horizontal crushing, and the hollow shaft is equipped with a Y-shaped or L-shaped flail for unsupported cutting, which invisibly consumes a lot of power, and the field conditions are more complicated. It is impossible to avoid the collision of the scalpel with stones and other hard objects, which is easy to damage the scalpel, and the recyc...

AI Technical Summary

Problems solved by technology

Most of the existing straw crushing and recycling machines adopt horizontal crushing, and the hollow shaft is equipped with a Y-shaped or L-shaped swing knife for unsupported cutting, which consumes a lot of power invisible, and the field conditions are more complicated. , it is impossible to avoid the collision between the throwing knife and hard objects such as stones, which is easy to damage the throwing knife, and the straw recycled in this way has a lot of dust, which makes it difficult to guarantee the quality of the recycled straw. A lot of dust is generated during work, which damages the environment. poor condition
