Chinese medicine refers to substances that are used to prevent, treat, diagnose diseases and have rehabilitation and health care effects under the guidance of traditional Chinese medicine theory. Chinese medicine mainly comes from natural medicines and their processed products, including herbal medicines, animal medicines, mineral medicines, and some chemical and biological products. Since most Chinese medicines are herbal medicines, there is a saying that "all medicines are based on herbs." When using Chinese medicine, it often needs to be crushed.

[0003] The utility model patent with authorization announcement number CN215197462U discloses a centrifugal crushing mechanism for traditional Chinese medicinal materials, including a protective box, a second drive motor is installed on one side of the lower end of the protective box, two rotating shafts are rotatably connected to the opposite side walls in the protective box, a drive wheel is fixedly mounted on the rotating shaft, and the two drive wheels are connected by a drive belt transmission. The output shaft of the second drive motor passes through the side wall of the protective box and is fixed to the lower end of one of the rotating shafts, the upper ends of the two rotating shafts are respectively connected with L-shaped connecting rods, and the L-shaped connecting rods are rotatably sleeved on the side walls of the protective box, a crushing barrel is fixed to the upper end of the L-shaped connecting rod, and a support mechanism is provided on one side of the protective box.

[0004] Although this technical solution can effectively and quickly crush Chinese medicinal materials through the crushing barrel, and can improve the efficiency and quality of crushing through the dual centrifugal setting, greatly improving the rapid crushing progress of Chinese medicine, and at the same time ensuring the quality after crushing; but under this technical solution, the medicinal materials in the crushing barrel cannot be turned over, resulting in insufficient crushing of the medicinal materials, and it is inconvenient to export the crushed medicinal materials. In view of this, we propose a medicinal material centrifugal crusher. Utility Model Content
