Technical Field

[0001] The utility model relates to the technical field of medicinal material processing, in particular to a medicinal material crushing device. Background Art

[0002] A medicinal material grinder is a machine specially used for grinding Chinese medicinal materials. In the production of Chinese medicine, it is often necessary to grind the medicinal materials to make their efficacy easier to exert. The commonly used grinding device is a machine that grinds large-sized solid raw materials into the required size.

[0003] The current pulverizing device on the market includes a barrel, in which a pulverizing mechanism and a screen are arranged. After the material is pulverized by the pulverizing mechanism, it falls through the screen. This type of device has the following defects: 1. The material piled up on the screen is easy to cause the screen to be blocked, affecting the discharge efficiency, and in serious cases, causing the equipment to shut down; 2. The material above the screen is hit against the barrel wall by the pulverizing mechanism and cannot be effectively broken, resulting in low material breaking efficiency. Therefore, a medicinal material pulverizing device is needed to solve the problem that the screen inside the pulverizing device is easy to be blocked and the material cannot be effectively broken.
