The shifting rod 20 on the same side cooperates with the driving rod 19. When the conveyor 9 is started, the shifting rod 20 is driven to rotate, and the shifting rod 20 pushes the mounting shaft 18 and the mounting frame 10 to rotate through the driving rod 19. Then, after the shifting rod 20 is out of contact with the driving rod 19, the mounting frame 10 is reset, thereby generating a shake, which facilitates the falling of raw materials and debris and prevents accumulation and blockage.

[0036] The ball-making mechanism is arranged in the box 1 to make balls for the raw materials;

[0037] The recycling mechanism is also provided on one side of the box body 1 to recycle the scraps.
