A device for crushing and screening medicinal materials for traditional Chinese medicine processing

Abstract

The invention discloses a medicinal material crushing and screening device for traditional Chinese medicine processing. The device comprises a crushing box. A motor rack is fixedly mounted on the topof the crushing box; two adjusting plates are rotatably arranged in the crushing box in symmetry of a driving shaft; a lead screw is horizontally arranged through the side wall of the crushing box through threaded connection, the lead screw extends into the crushing box and leans against the adjusting plates, and a second limiting spring is connected between a sieve plate and an extension plate. By rotating the adjusting plates, the traditional Chinese medicinal materials can be closer to a cutting blade, so that the cutting and crushing efficiency of the cutting blade is improved greatly; meanwhile, the device is convenient to adjust and suitable for crushing medicinal materials of different sizes; a horizontal shaft drives a cam to rotate, so that the sieve plate vibrates up and down toenable the crushed medicinal materials to be uniformly paved to the sieve plate, and meanwhile, finely-divided medicinal material powder penetrates through the sieve plate quickly to be screened, flowing of an air flow in the crushing box is accelerated as a vane rotates, so that sieve pores of the sieve plate can be prevented from being blocked by the medicinal materials and the screening efficiency of the medicinal materials is increased.

Description

technical field [0001] The invention relates to the technical field of medicinal material processing, in particular to a crushing and screening device for traditional Chinese medicine processing medicinal materials. Background technique [0002] Medicinal materials are the raw materials for pharmaceuticals, especially Chinese medicinal materials in China, that is, raw materials of traditional Chinese medicine that have not been processed or made into finished products. Chinese medicine is a traditional Chinese medicinal material. Chinese medicine culture has a long history and is extensive and profound. It not only includes thousands of years of Chinese medicine civilization, but also integrates modern and modern Western medicine civilization to create a unique cultural phenomenon that combines Chinese and Western medicine. It is an important part of China's excellent culture. The development and effective utilization of Chinese medicinal materials has a long history and is ...

AI Technical Summary

Problems solved by technology

[0003] Before the processing and pharmacy of Chinese medicinal materials, it is necessary to crush and refine the medicinal materials, and obtain relatively fine Chinese medicinal materials through the screening of sieves, so as to facilitate the subsequent processing of medicinal materials. It is not ideal enough, the adjustment is poor, and the screening speed is slow, which is easy to cause the blockage of the screen mesh
