AI Technical Summary
Existing millet selection machines do not completely separate impurities and have low screening efficiency, making it difficult to meet the demand for high-quality selection.
It adopts a multi-layer screening structure, including large-hole and small-hole screen cylinders rotating in opposite directions. Combined with the design of spiral blades and scrapers, it can achieve layered screening and impurity removal. The lifting cylinder facilitates the maintenance of the large-hole screen cylinder.
It achieves multi-layer fine screening of millet, thoroughly removes impurities, improves screening efficiency and effect, reduces maintenance difficulty, and meets the needs of high-efficiency fine selection.
