Description

Seed sieving mechanism is used in chinese herbal medicine planting Technical Field The utility model relates to the field of Chinese herbal medicine planting, in particular to a seed screening device for Chinese herbal medicine planting. Background The herbal medicine is prepared from plant extracts, and is mainly used for treating the disease. Since most plants contain chemical elements, there are physical treatments such as healing. Herbal medicine is the oldest health care mode and plays an important role in ancient times. Today, the development of modern medicine is still an unvented technique. The original human uses the wide flora to observe animals and plants and parts thereof to the maximum extent, and the herbal medicine is born and scientific and technological progress finally, thus creating chemical medicines and new biological medicines. The whole pharmacy has obtained great progress from research technology, production technology to professional management technology. Meanwhile, the plant medicine which is relatively stagnant for a long time is newly developed along with the progress of science and management. The herbal formulation has three stages of development. The first stage is traditional pill, paste, and powder. In the second stage, the extraction and coarse treatment technology based on hydroalcoholic method or alcohol-water method is combined with modern industrial preparation technology to prepare the Chinese patent medicine. And in the third stage, modern plant medicine is refined and quantified by using modern separation technology and detection technology. Most of the existing seed screening devices for Chinese herbal medicine planting are single in structure, the screening efficiency is low, and fine particles such as dust doped in the Chinese herbal medicine in the screening process can cause certain harm to the body of operators.
