[0022] The other side of the movable jaw plate 6 is fixedly connected to a first fixing device, to which a first transmission shaft 10 is rotatably connected. The other side of the first transmission shaft 10 is rotatably connected to a transmission plate 9 , which is triangular and located inside the transmission box 2 .

[0023] The other side of the transmission plate 9 is rotatably connected to the second transmission shaft 11, and the other side of the second transmission shaft 11 is rotatably connected to the second fixing device. The second fixing device is fixedly connected to the inside of the device body 1, and the lower sides of the transmission plate 6 are fixedly connected to connecting rods, and the first transmission shaft 10 and the second transmission shaft 11 are rotatably connected to the connecting rods respectively.

[0024] The top of the transmission plate 9 is rotatably connected to an eccentric turntable 12. The middle part of the eccentric turntable 12 is fixed to the inside of the device body 1 through a transmission rod. A circular hole is opened at the eccentric position of the eccentric turntable 12 and is rotatably connected to the top of the transmission plate 9. The eccentric turntable 12 rotates in a circle around the transmission shaft. The rotation of the eccentric turntable 12 drives the transmission plate 9 to perform eccentric movement.

[0025] The outer rotation of the eccentric turntable 12 is connected to the crawler belt 13, and the other end of the crawler belt 13 is connected to the motor 14. The output shaft of the motor 14 is fixedly connected to the track wheel. The outer installation of the track wheel is by the crawler belt 13. The motor 14 is fixed inside the transmission box 2.

The material enters the crushing chamber through the feed port 7. After the material enters the crushing chamber, the movable jaw plate 6 is driven by the motor 14 to perform periodic reciprocating motion. The material is subjected to the extrusion force between the movable jaw plate 6 and the fixed jaw plate 5, so that the material is continuously crushed in the crushing chamber and finally discharged from the discharge port 8. The gap width between the movable jaw plate 6 and the fixed jaw plate 5 can be adjusted by rotating the limit bolt 4 to control the size of the discharged particle size.

[0029] Compared with the prior art, the present invention has the following beneficial effects:
