[0025] A feeding module is provided on the right side of the first crushing module, a blowing module is provided on the right side of the second crushing module, and a discharging module is provided on the wall of the crushing barrel 2 at a position opposite to the blowing module.

[0026] The first crushing module includes a first crushing motor 3, which is vertically and downwardly mounted on the top of the crushing barrel 2. Several connecting rods 5 are fixed on the rotor of the first crushing motor 3. An annular rod 6 is fixed at one end of the connecting rod 5. Several first crushing rods 7 are connected below the annular rod 6. Several first crushing fan blades 8 are provided on the first crushing rods 7.

[0027] The second crushing module includes a second crushing motor 4, which is vertically mounted at the bottom of the crushing barrel 2. A rotating shaft 10 is fixed on the rotor of the second crushing motor 4, and several second crushing rods 11 are connected to the rotating shaft 10. Several second crushing blades 12 are provided on the second crushing rods 11.

[0028] In this embodiment, the first crushing blade 8 can crush the material at the edge of the crushing barrel 2, and the second crushing blade 12 can crush the material in the middle and bottom of the crushing barrel 2, thereby improving the crushing efficiency.

[0029] A first rotating rod 13 is provided on the left side of the crushing barrel 2, and a second rotating rod 14 is provided on its right side. The first rotating rod 13 is rotatably located on the left side of the crushing support 1, and the second rotating rod 14 is rotatably located on the right side of the crushing support 1. A rotating motor 15 is horizontally provided on the right side of the crushing support 1, and the rotor of the rotating motor 15 is fixedly connected to the second rotating rod 14.

[0030] In this embodiment, the rotating motor 15 can drive the crushing barrel 2 to swing back and forth on the crushing support 1. During the swinging process, the material swings back and forth in the crushing barrel 2, so that it can make more full contact with the crushing blades and improve the crushing effect.

[0031] The feeding module includes a feeding hopper 16, and a feeding screw conveyor 17 is connected to the bottom of the feeding hopper 16. The conveying pipe of the feeding screw conveyor 17 extends into the interior of the crushing barrel 2.
