[0002] Medicinal materials are raw materials for making medicines, especially Chinese medicinal materials in China. Chinese medicinal materials are picked, dried and transported to processing plants for processing. Chinese medicinal materials are generally in the form of strips, blocks and roots, so they need to be cut into blocks, segments and strips. A large amount of Chinese medicinal material debris will be generated during the cutting process of Chinese medicinal materials. The mud and sand attached to the surface of the Chinese medicinal materials will be shaken off during the cutting process, and this part of the debris and mud and sand will also become impurities in the Chinese medicinal materials. Moreover, since Chinese medicinal materials are generally placed on the ground for drying during the drying process, they will be exposed to a large amount of mud and dust during the drying process, and a small amount of stones will be attached to some Chinese medicinal materials. In order to ensure the quality of Chinese medicinal materials, these impurities need to be removed. The existing method of removing impurities is generally through air separation, which is classified and screened according to the difference between medicinal materials and impurities. However, due to the relatively large weight and volume of stones, the stones are basically mixed in the medicinal materials. Therefore, in order to solve the above technical problems, the technical solution of the present application is set up. Utility Model Content
