A transmission shaft 22 is fixedly connected to the left side of one end of the transmission gear 16. A drive sleeve 15 is movably connected to the outside of the drive shaft 22. A connecting arm 20 is fixedly connected to the left side of the drive sleeve 15. A drive shaft 17 is movably connected to the right side inside the machine compartment 1. Drive gears 18 are fixedly connected to both ends outside the drive shaft 17. A drive motor 21 is fixedly connected to the right side of the rear end of the machine compartment 1.

[0027] The connecting arm 20 is hinged to the crushing plate 2, and the drive gear 18 is meshed with the transmission gear 16.

[0028] The output end of the drive motor 21 passes through the rear end of the housing 1 and is fixedly connected to the drive shaft 17. The center line of the drive shaft 17 and the center line of the drive gear 18 are on the same vertical plane.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, during crushing, the start drive motor 21 drives two sets of drive gears 18 to rotate synchronously via the drive shaft 17. The drive gears 18 then drive the transmission gear plate 16 at the bottom to rotate. The transmission gear plate 16 drives the drive sleeve plate 15 to reciprocate via the drive shaft 22. Finally, the drive sleeve plate 15 drives the crushing plate 2 to move continuously via the connecting arm 20 to facilitate crushing. The connecting arm 20 is equipped with a limit component to limit the connecting arm 20, so as to ensure the stability of pushing the crushing plate 2. Furthermore, the synchronous pushing of the crushing plate 2 from both ends can effectively improve the stability during crushing, thus achieving improved driving stability during crushing.

[0030] The left side of the machine compartment 1 is movably connected to a first jaw plate 4. The left side of the machine compartment 1 is provided with an installation slot 23. The left side of the first jaw plate 4 is fixedly connected to a connecting plate 9. The left sides of both ends of the connecting plate 9 are fixedly connected to positioning plates 8. The left side of the machine compartment 1 is provided with a cavity 5. The left side of the cavity 5 is fixedly connected to an ejector spring 6. The right side of the ejector spring 6 is fixedly connected to a push plate 7. The right side of the push plate 7 is fixedly connected to three sets of positioning pins 25. The left side of the connecting plate 9 is provided with three sets of positioning slots 24. The left side of the crushing plate 2 is provided with an installation groove 28. The installation groove 28 is movably connected to an installation insert plate 26. The left side of the installation insert plate 26 is fixedly connected to a second jaw plate 10. The two ends of the installation insert plate 26 are provided with two sets of threaded holes 27. The two ends of the crushing plate 2 are movably connected to fixing bolts 19.

[0031] The fixing bolt 19 extends into the mounting groove 28 and is threaded into the threaded hole 27; the positioning pin 25 extends into the mounting slot 23 and is movably connected to the positioning slot 24.

[0032] The positioning plate 8 is slidably connected to the mounting slot 23, and the connecting plate 9 is movably connected to the mounting slot 23.

[0033] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, after a long period of crushing, the push plate 7 inside the cavity 5 can be pulled to disengage the positioning pin 25 from the inside of the positioning slot 24. Then, the first jaw plate 4 can be pulled upward to disengage the connecting plate 9 from the inside of the mounting slot 23 for maintenance and repair of the first jaw plate 4. After that, the fixing bolt 19 can be rotated to disengage it from the threaded hole 27, and the second jaw plate 10 can be removed for maintenance and repair. This allows for quick disassembly, repair, or replacement of the first jaw plate 4 and the second jaw plate 10.

[0034] Support rods 11 are movably hinged at both ends of the bottom right side of the crushing plate 2. A fixing plate 12 is fixedly connected to the outside of the support rod 11.

[0035] The reset spring 13 is fixedly connected to the limiting sleeve 14, and the support rod 11 extends into the interior of the limiting sleeve 14.

[0036] Specifically, such as Figure 1As shown, during crushing, the crushing plate 2 moves while driving the support rods 11 at both ends on one side to move continuously. The support rods 11 then push the return spring 13 through the fixing plate 12. The return spring 13 is connected to the limiting sleeve 14, which can push the crushing plate 2 during movement to ensure the power of the crushing plate 2 during crushing, thereby improving the crushing effect. It can also limit the crushing plate 2 to ensure the stability of the crushing plate 2 during movement, thus improving the crushing stability and ensuring the crushing effect.

[0037] Working Principle: In use, during crushing, the drive motor 21 drives two sets of drive gears 18 to rotate synchronously via the drive shaft 17. The drive gears 18 then drive the bottom transmission gear plate 16 to rotate. The transmission gear plate 16 drives the drive sleeve plate 15 to reciprocate via the drive shaft 22. Finally, the drive sleeve plate 15 drives the crushing plate 2 to move continuously via the connecting arm 20 for crushing. A limit component is provided on the outside of the connecting arm 20 to limit its movement, ensuring the stability of pushing the crushing plate 2. Simultaneous pushing of the crushing plate 2 from both ends effectively improves the stability during crushing. During crushing, the movement of the crushing plate 2 simultaneously drives the support rods 11 at both ends on one side to move continuously. The support rod 11 then pushes the return spring 13 through the fixing plate 12. The return spring 13 is connected to the limiting sleeve 14, which can push the crushing plate 2 during movement to ensure the power of the crushing plate 2 during crushing, thereby improving the crushing effect. It can also limit the crushing plate 2 to ensure the stability of the crushing plate 2 during movement. After a long period of crushing, the push plate 7 inside the cavity 5 can be pulled to drive the positioning pin 25 out of the positioning slot 24. Then, the first jaw plate 4 can be pulled upward to drive the connecting plate 9 out of the mounting slot 23 for maintenance and repair of the first jaw plate 4. Then, the fixing bolt 19 can be rotated to disengage it from the threaded hole 27 to remove the second jaw plate 10 for maintenance and repair.
