[0029] Working principle: When Chinese medicinal materials are crushed and added, when the Chinese medicinal materials fall into the connecting pipe 6, the rotating push rod 755 contacts the arc plate 85, and an upward pushing movement is generated, thereby driving the multiple dredging rods 86 connected thereto to move, thereby pushing the Chinese medicinal materials located at the connecting pipe 6 upward and dispersing them. At the same time, after breaking away from the contact with the arc plate 85, the sliding sleeve 84 and the U-shaped plate 81 are pushed downward by the spring 2 83, thereby driving the entire arc plate 85 and the dredging rod 86 move downward. During the continuous up and down movement of the dredging rod 86, the Chinese medicinal materials accumulated at the connecting pipe 6 are moved to promote the discharge of materials and avoid affecting the processing of the Chinese medicinal materials. At the same time, during the processing and crushing of the Chinese medicinal materials, the crushed Chinese medicinal materials will fall along the screen 73, and after passing through the separation plate 10, they will be classified into two particle sizes. The large particle size will fall along the inclined surface of the separation plate 10 and be collected along the coarse crushing cylinder 9, and the small particle size will fall along the discharge hopper 3 and be collected.
