Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medicine crushing, in particular to a medicine crushing and grinding device. Background Art
[0002] Chinese herbal medicine refers to medicines that are collected and processed under the guidance of traditional Chinese medicine theory to explain the mechanism of action and guide clinical application. They are mainly derived from natural medicines and their processed products, including vegetable oils, animal oils, mineral oils, and some chemical medicines, biological products, etc. The West is accustomed to calling herbal medicines natural medicines. Natural medicines refer to all medicines that are derived from nature and used to treat diseases without chemical treatment. Chinese medicine and herbal medicines should be included in their scope. Therefore, in order to better and fully utilize Chinese herbal medicines, they need to be effectively ground, which is more conducive to enabling patients to absorb the medicinal power of Chinese herbal medicines and has a good effect on daily treatment and health.
[0003] Traditional Chinese medicine grinding processing generally utilizes a stone mill. The traditional stone mill includes a trough-shaped stone mill base, on which a roller is rolled. The roller is operated manually or by feet to roll in the stone mill base to crush the Chinese medicinal materials. However, although the above-mentioned crushing method has a good grinding effect, the processing operation is particularly laborious. The existing electric grinders are mostly blade-type structures, in which the blades are connected to the motor. During the high-speed rotation of the motor-driven blades, the medicinal materials are crushed. Although the existing electric grinders have high grinding efficiency, the blades actually only crush the medicinal materials during rotation, and the smaller tissues inside the medicinal materials cannot be crushed, and the effective medicinal components of the Chinese medicinal materials cannot be broken and released. For this reason, we propose a drug crushing and grinding device to solve the above problems. Utility Model Content
