Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material processing equipment, in particular to a medicinal material screening and crushing device. Background Art

[0002] Generally, traditional Chinese medicinal materials emphasize authentic medicinal materials, which refer to medicinal materials produced in a region with specific natural conditions and ecological environment. Because the production is relatively concentrated, the cultivation technology, harvesting and processing also have certain requirements, so that the quality and efficacy of the same medicinal materials produced in other regions are better.

[0003] As the concept of traditional Chinese medicine is deeply rooted in people's hearts, the use of traditional Chinese medicine is becoming more and more popular. In order to improve the efficacy of traditional Chinese medicine, many raw materials of traditional Chinese medicine need to be crushed and screened for subsequent use. After searching, the Chinese patent application number is: CN201810910418.4, which discloses a crushing and grinding device for the production and processing of traditional Chinese medicine in the field of traditional Chinese medicine processing technology, including a feed hopper, a feed pipe, a fixed box, a screening box, a crushing box and a grinding box. The invention puts the traditional Chinese medicine into the feed hopper and then enters the crushing box along the feed pipe. The crushing mechanism crushes the Chinese medicinal materials. After crushing, the feed port of the crushing box rotates downward, the Chinese medicinal materials are screened by the screening box, and then the crushing box rotates to the feed port upward. The Chinese medicinal materials that have not passed through the first screen pass through the shovel surface at the feed port and return to the crushing box, and are crushed for the second time with the next batch of crushed medicinal materials. After the Chinese medicinal materials enter the grinding box, they are ground by the grinding mechanism. At the same time, the ground medicinal powder is sent to the powder outlet through the rotating brush to avoid the ground medicinal powder remaining in the grinding tank and repeatedly ground to cause the powder particles to be too fine, and the grinding effect is good.

[0004] The above technical solution and traditional medicinal material processing equipment both have the following defects, that is, they can only perform single-item processing on Chinese medicinal materials, and additional equipment is required for screening after crushing, which prolongs the medicinal material processing process and reduces the processing efficiency. Therefore, we need to propose a medicinal material screening and crushing device. Utility Model Content
