Screening device of medicinal material crusher and cyclic crushing system thereof

Abstract

The invention discloses a screening device of a medicinal material crusher and a cyclic crushing system thereof, and relates to the field of medicinal material crushers, the screening device comprises a machine box body, a screening device and a cyclic crushing system, the top of the machine box body is provided with a crushing chamber, the screening device is arranged in the screening chamber in the machine box body, and the cyclic crushing system is arranged on one side of the screening device; the device has the beneficial effects that medicinal materials diced through the crushing chamber fall into a coarse filter plate arranged in the screening chamber, coarse and fine medicinal material particles are screened through the coarse filter plate, the fine-particle medicinal materials are screened through the coarse filter plate and fall onto a fine filter plate, medicinal material chippings in the fine medicinal materials are filtered through the fine filter plate, and the medicinal material chippings in the fine medicinal materials are filtered through the fine filter plate; granular medicinal materials screened by the coarse filtering plate are guided and conveyed into the material returning box, meanwhile, the lifting rotating shaft is driven by the lifting motor, so that the coarse medicinal material particles stored in the material returning box are lifted by the material guiding blades arranged on the lifting rotating shaft, and finally, the coarse medicinal material particles are discharged into the feeding hopper through the discharging opening in the upper end of the lifting barrel and enter the crushing chamber again for cyclic crushing.

Description

technical field [0001] The invention relates to the field of medicinal material crushers, in particular to a screening device of a medicinal material crusher and a circulation crushing system thereof. Background technique [0002] In the production process of traditional Chinese medicine, it is necessary to use mechanical equipment to crush large solid materials into appropriate fineness, select medicinal materials with appropriate particle size, and facilitate decoction. The crushing and screening in the traditional processing process are carried out in different devices, increasing The production process affects the production efficiency; in the traditional medicinal material crushing machine, due to the different sizes of the Chinese medicine particles cut by the cutting device, the prepared Chinese medicine particles are not uniform, which will be affected in the subsequent drying process. Usually, the materials are repeatedly crushed manually, and the processing efficie...

[0002] In the production process of traditional Chinese medicine, it is necessary to use mechanical equipment to crush large solid materials into appropriate fineness, select medicinal materials with appropriate particle size, and facilitate decoction. The crushing and screening in the traditional processing process are carried out in different devices, increasing The production process affects the production efficiency; in the traditional medicinal material crushing machine, due to the different sizes of the Chinese medicine particles cut by the cutting device, the prepared Chinese medicine particles are not uniform, which will be affected in the subsequent drying process. Usually, the materials are repeatedly crushed manually, and the processing efficiency is low; in the traditional medicinal material crushing equipment, a large amount of medicinal powder and debris will be produced when the medicinal material is crushed, and these medicinal powder and debris are mixed into the medicinal material granules, which will affect the production quality of the medicinal material
