[0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting seeds. More than half of the products of crop photosynthesis are present in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. Straw is also a roughage. When processing straw, it is usually returned to the field.

[0003] The Chinese invention patent with patent publication number CN116114415B cooperates with a straw crushing box and a straw crushing rod, so that when the device is in use, the straw can be poured into the interior of the straw crushing box through a straw feeding funnel, and then the straw inside the straw crushing box is crushed by the rotation of the crushing shaft and the straw crushing rod; however, there are some shortcomings when the above device is actually used.
