[0040] In this invention, when the vertical vibrating classifying crusher is in use, the material to be crushed is first injected through the feed inlet 11. When the motor 12 rotates, it can drive the crushing mechanism 4 to rotate. At this time, multiple sets of crushing blades 43 will continuously rotate around the drive shaft 41 under the action of the "Z"-shaped guide groove 441 of the positioning shaft 44. The blades of the multiple sets of crushing blades 43 will continuously flip from a horizontal position to a vertical position and then flip back to a horizontal position. Then, the crushing blades 43 push the material on the screening seat 42 below to impact the crushing teeth of the crushing barrel 13 to crush the material. Compared with the traditional fixed push plate structure, it can effectively prevent large pieces of stone from being crushed. The material piled up on the screening seat 42 improves the crushing efficiency of the crusher 1. The cleaning brush 45 can continuously scrape and clean the inner wall of the crushing barrel 13 (i.e., the gap between the crushing teeth) during the rotation of multiple sets of crushing blades 43, effectively removing the debris stuck or attached to the surface of the crushing teeth in the crushing barrel 13, and preventing small debris from getting stuck and blocking the normal operation of the crusher 1. The screening machine 2 set at the bottom of the crusher 1 can further screen the crushed material. Larger materials that are still not completely crushed after screening will be sent back to the feed inlet 11 through the circulation conveying mechanism 3 to enter the crusher 1 for repeated crushing, further improving the crushing effect of the material.
