Straw 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 the 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, characterized by a high crude fiber content (30%-40%) and lignin.

In this way, if part of the unscreened straw is screened out during the rotation of the inner screen drum, it will be blocked by the baffle, and the intercepted straw will fall into the inner screen drum to continue to screen out sand and soil. Therefore, the utility model can reduce the sand and soil content of the screened straw and improve the screening efficiency.

[0004] However, the above scheme still has some shortcomings. For example, in the above scheme, due to the large centrifugal force of the sand during rotation, the sand is easily thrown out from the top and both sides and scattered everywhere, which is inconvenient for users to clean.
