[0002] Straw is a general term for the stems and leaves of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops after the seeds are harvested. More than half of the products of crop photosynthesis are present in the straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. In agricultural production, straw is an important agricultural residue, and its effective utilization and treatment are of great significance to environmental protection and resource recycling.

In addition, the straw is easy to move during the cutting process, resulting in inaccurate cutting, affecting product quality. For this reason, the utility model provides a straw raw material sorting cutting machine. Utility Model Content
