Corn straw crushing device

Abstract

The invention relates to a corn straw crushing device and belongs to the technical field of crop processors for agricultural harvesting. The crushing device comprises a shell, wherein the shell is internally provided with a first rotary shaft, a driving shaft, a driven shaft, a second rotary shaft, a movable rubbing plate and a fixed rubbing plate; the first rotary shaft, the driving shaft, the driven shaft and the second rotary shaft are arranged in a manner of being parallel to each other; the movable rubbing plate and the fixed rubbing plate are arranged relatively up and down; the first rotary shaft and the second rotary shaft are located at the inlet and the outlet of the crushing device respectively; the driving shaft and the driven shaft are located between the first rotary shaft and the second rotary shaft; a longitudinal cutter is fixedly arranged on the first rotary shaft and a transverse cutter is fixedly arranged on the second rotary shaft; the movable rubbing plate is a conveyor-belt-shaped rubbing plate formed by mutually connecting plate-shaped rubbing plates; the front and rear ends of the movable rubbing plate sleeve the driving shaft and the driven shaft respectively; a straw rubbing channel is formed between the movable rubbing plate and the fixed rubbing plate. With the adoption of the crushing device, corn straws can be conveniently and rapidly crushed to specific sizes so that subsequent bundling and film packaging work can be conveniently carried out.

Description

technical field [0001] The invention relates to a corn stalk crushing device, which belongs to the technical field of crop processing machines for agricultural harvesting. Background technique [0002] Corn is one of the most important food crops in my country, with an annual output of more than 200 million tons. During corn harvesting operations, a large amount of corn stover is produced. [0003] The treatment methods of corn stalks mainly include direct incineration, straw returning to the field and straw recycling. However, the direct burning of straw not only pollutes the environment, but also causes waste of resources, and there are many safety hazards; using straw to return to the field on the spot consumes a lot of power, and the operating cost is high, which is prone to land nutritional imbalance, soil-borne diseases and insect pests, and slow straw maturity More importantly, it may lead to difficulties in planting the next crop in non-single-season planting areas...

AI Technical Summary

Problems solved by technology

[0008] The present invention adopts the above-mentioned technical scheme, thereby bringing the following effects: the stalk is cut along its moving direction (longitudinal direction) by the longitudinal cutter, so that the size of the stalk on the section is reduced; the stalk after slitting is moved The interactive rubbing board and the fixed rubbing board rub the straw so that the size of the straw in the section is reduced again. Finally, the straw that has been rubbed into filaments is cut into a controllable length along the transverse direction by a horizontal cutter. It is convenient and fast to crush corn stalks to specific specifications, which is beneficial to the subsequent bundling and comprehensive utilization of straw, and completely solves the problem of using separation operations. The size of corn stalk crushing and the size required for straw baling are very different from each other, which cannot be done well. The difficulty of bundling and coating the corn stalks, so that the subsequent bundling and coating can be carried out properly
