Multi-stage crushing device for Chinese medicinal material production

Abstract

The invention discloses a multi-stage crushing device for Chinese medicinal material production and relates to the field of Chinese medicinal material processing. The multi-stage crushing device comprises a crushing box. The two sides of the top of the crushing box are both fixedly connected with feed hoppers. A first driving motor is fixedly connected to the center of the top of the crushing box.An output shaft of the first driving motor penetrates through the crushing box to be fixedly connected with a rotary shaft. A first crushing knife set and a second crushing knife set are arranged onthe rotary shaft. A material distribution device and a screen net are arranged in the crushing box from top to bottom in sequence. The multi-stage crushing device can conduct two-stage separated crushing on Chinese medicinal materials through the first crushing knife set and the second crushing knife set, ensures the uniformity of the crushed Chinese medicinal materials, can conduct cutting on Chinese medicinal material fragments clamped discharge holes through the material distribution device, can screen out the Chinese medicinal material fragments meeting the size requirement through the screen net and vibration motors, can prevent the situation that mesh holes of the screen net is blocked by the Chinese medicinal material fragments and is perfect in Chinese medicinal material processingeffect and good in cutting and crushing effect.

Description

technical field [0001] The invention relates to the field of processing Chinese medicinal materials, in particular to a multistage crushing device for the production of Chinese medicinal materials. Background technique [0002] Chinese medicinal materials are the precious wealth accumulated by the Chinese nation in the process of fighting against diseases. The use of Chinese medicinal materials has extremely strict requirements on the state of the medicinal materials themselves. In the processing of Chinese herbal medicines, the crushing of Chinese herbal medicines is usually involved. [0003] In the Chinese utility model patent document with the publication number CN207042578U, a Chinese medicinal material crushing device is disclosed. The device is provided with the first sawtooth, the second sawtooth, the third sawtooth and the fourth sawtooth respectively matched therewith, so that the rhizome Chinese medicinal materials It can be cut thoroughly and evenly, and fine an...

[0003] In the Chinese utility model patent document with the publication number CN207042578U, a Chinese medicinal material crushing device is disclosed. The device is provided with the first sawtooth, the second sawtooth, the third sawtooth and the fourth sawtooth respectively matched therewith, so that the rhizome Chinese medicinal materials It can be cut thoroughly and evenly, and fine and uniform Chinese herbal medicines can be obtained after three times of cutting. However, in the actual use process, Chinese herbal medicines will have the disadvantage of insufficient cutting, and important broken particles will block the mesh of the screen, resulting in lower The material is not smooth, and the crushing and cutting process has certain defects and flaws
