[0002] Chinese herbal medicines are Chinese medicinal materials that have been processed and prepared according to the theories of traditional Chinese medicine and Chinese medicine preparation methods and can be directly used in clinical Chinese medicine. With the continuous improvement and maturity of the preparation theory, Chinese herbal medicines have become an important means of clinical disease prevention and treatment in Chinese medicine. Chinese herbal medicines use Chinese herbal medicines as raw materials and need to go through multiple processing steps. Chinese herbal medicines are in direct contact with the soil, and the rhizomes of Chinese herbal medicines are often mixed with more dirt and sand. Therefore, the first step in the preparation of Chinese herbal medicines is to remove these dirt, stones and debris.

[0003] At present, Chinese herbal medicine manufacturers usually use screening beds to directly screen raw materials. They are unable to deal with dust and fine impurities in the raw materials in advance, which requires staff to perform additional processing on the raw materials later, resulting in poor screening effect and low work efficiency. In addition, when the raw materials mixed with dust and fine impurities are directly put into the screening bed for vibration screening, the dust and fine impurities will drift into the surrounding environment under the action of the high-speed vibrating screening bed, resulting in a poor working environment in the screening workshop, which has an adverse effect on the health of the staff.

[0006] Preferably, the dust removal assembly includes a filter box and an exhaust fan respectively fixed on the top of the base plate, the air outlet end of the filter box is fixedly connected to the air inlet end of the exhaust fan by a connecting pipe, and a side wall of the box body is provided with an air outlet connected to the dust removal chamber.

[0007] Preferably, the air inlet end of the filter box is fixedly connected to a delivery pipe, the top end of the delivery pipe is fixedly connected to an air collecting hood, the air collecting hood is fixed on a side wall of the box body, and the air collecting hood covers the air outlet.

[0008] Preferably, an air supply pipe is provided on one side of the box body close to the material cavity, a fan is fixed to the inner wall of the air supply pipe, an air supply hood is fixed at one end of the air supply pipe, and the air supply hood is fixed on one side wall of the box body.

[0009] Preferably, a side wall of the box body is provided with an air supply port connected to the air supply hood.

[0010] Preferably, the top of the box body is fixedly connected with a feed inlet, the bottom of the box body is fixedly connected with a discharge hopper connected with the material cavity, and the discharge hopper is located above the sieve bed.

[0011] Preferably, four legs are respectively fixed on the surface of the box body, and the bottoms of the four legs are fixed on the top of the bottom plate.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] In the utility model, by arranging the drainage plate, the material cavity, the dust removal cavity and the dust removal component, the drainage plate can increase the flow time of the medicinal materials in the box body, and under the guidance of the lowest drainage plate, the medicinal materials can fall downward from the high position of the material cavity, and with the cooperation of the dust removal component, the dust and light-weight impurities mixed in the raw materials can be attracted into the dust removal cavity and filtered during the falling process, and the medicinal materials after dust removal continue to fall downward and fall into the sieve bed below for screening of particulate impurities, so that the dust and light-weight impurities can be filtered first to avoid these dust impurities from polluting the surrounding working environment, thereby maintaining the working environment during the screening of medicinal raw materials and improving the work efficiency of the production of Chinese herbal medicine slices.
