Description

a crushed structure

technical field

The utility model relates to a crushing structure.

Background technique

For solid raw materials, such as medicinal materials, fruits, meat and other raw materials, when they need to be crushed, they are usually crushed by a pulverizer. The crushing structure installed inside the pulverizer is a cutter. The high-speed rotating cutter will instantly break and chop the raw materials. The crushed raw materials are obtained, but the following disadvantages are found during the use of the cutter: First, when a single blade rotating at high speed crushes the raw materials, a spiral swirl will be formed inside the container, and the raw materials that have not been crushed will be crushed under the action of centrifugal force. , will be far away from the blade and cannot be in direct contact with the blade, so that the raw material cannot be completely crushed into fine particles; the second is that the production cost is relatively high due to the high requirements for the speed of the blade and the sharpness of the cutting edge.
