Description

technical field [0001] The invention relates to the field of straw crushing equipment, in particular to a large-scale straw crushing machine. Background technique [0002] During the cutting process, wheat, corn and other stalks are usually left in the farmland. The remaining stalks in the farmland will affect the rotary tillage of the land and the next use of the land. The treatment of the straw is usually incineration, which will cause the damage of the straw. Waste and environmental pollution. In fact, straw can be crushed and recycled into organic fertilizer, board and fuel for crops. It not only recycles resources, but also avoids environmental pollution. However, the existing straw grinder has a low degree of automation. Manual operation is required, and the straw is likely to be blocked during the crushing process, which greatly affects the production efficiency. Contents of the invention [0003] In view of the above problems, research and improvement have been ca...
