Technical Field

The invention relates to the technical field of traditional Chinese medicine material crushing and screening equipment, in particular to a traditional Chinese medicine material crushing and screening machine with a filter screen convenient to clean and a using method thereof.

Background

The medicinal materials can be used as raw materials for preparing medicines, in particular to Chinese medicinal materials, namely raw materials of Chinese medicaments which are not processed or prepared into finished products. The traditional Chinese medicine is a traditional Chinese medicinal material, has long-flowing and extensive and profound Chinese medicine culture source, not only contains thousands of years of traditional Chinese medicine civilization, but also integrates the cultural phenomenon of traditional Chinese medicine and western medicine created by the civilization of modern western medicine, and is an important component of excellent Chinese culture.

The Chinese medicine is mainly prepared from natural medicines and processed products thereof, including plant medicines, animal medicines, mineral medicines and partial chemical and biological products. Because the traditional Chinese medicines are mostly prepared from plant medicines, there is a saying that the medicines are prepared from herbs.

The Chinese medicinal materials refer to crude drugs applied under the guidance of Han nationality traditional medicine technology, and are used for treating diseases. The distribution and production of natural medicinal materials cannot be separated from certain natural conditions.

The production of various medicinal materials has certain regionality regardless of varieties, yield and quality. The traditional Chinese medicinal materials are produced in regions with specific natural conditions and ecological environments, and the traditional Chinese medicinal materials are concentrated in production, and have certain elaboration in cultivation technology, harvesting and processing, so that the traditional Chinese medicinal materials are better in quality and better in curative effect than the traditional Chinese medicinal materials produced in other regions.

Before the medicine is applied or made into various dosage forms, the necessary processing process is carried out according to the requirements of medical treatment, modulation and preparation.

The commonly used processing methods include repairing, water-making, fire-making, water-fire-making and the like. The processing aims at purifying the medicinal materials, ensuring the quality, sorting the medicines and grading; cutting into pieces, and making into preparation; drying the medicinal materials, and facilitating storage; the taste and the odor are corrected, and the medicine is convenient to take; the toxic and side effects are reduced, and the safe medication is ensured; the functions of the medicine are enhanced, and the clinical curative effect is improved; change the performance of the medicine and expand the application range. The guiding of the medicine into the channels is convenient for the directional medication.

A large amount of plants can be as the medicinal material, and some animal products also can be as the medicinal material such as snake gall, bear gall, the five-step snake, the pilose antler, the antler, when making traditional chinese medicine medicinal material, all need pound prepared medicinal material to pieces into tiny particle or powder with convenient the taking usually, current comparatively common crushing method is pounded to pieces through the manual work, such method crushing effect is relatively poor, crushing efficiency is also not high, in-process need consume a large amount of manpowers, work efficiency receives artificial restriction.

Therefore, some automatic medicinal material crushing machines are available in the market, but most of the machines only have a crushing function and cannot perform screening, so that finished product particles with different crushing sizes are mixed together; some traditional Chinese medicines have the functions of crushing and screening, but due to the defects of structural design, the traditional Chinese medicines are easy to form accumulation in the screening process, so that a filter screen is blocked, and equipment is blocked; and the filter screens of these devices are mostly built-in, are inconvenient to clean and need to be improved.
