Slide rods 331 are fixedly connected on both sides of the extrusion plate 33. A limited inclined groove 322 is provided on one side of the synchronous plate 32. The slide rod 331 is slidably connected to the inside of the limited inclined groove 322. A regrinding groove 332 is provided inside the extrusion plate 33. The regrinding groove 332 is slidably connected to the inner plate 334. One side of the inner plate 334 is fixedly connected to the movable grinding plate 333. The bottom surface of the inner plate 334 is fixedly connected to an arc slider 35. The arc slider 35 penetrates the extrusion plate On the bottom surface of the plate 33, an offset plate 36 is provided inside the crushing box 1, and an inner arc groove is opened inside the offset plate 36. The arc-shaped slider 35 is slidably connected to the inner arc groove. In the process of the movable jaw pressure block 27 cooperating with the fixed jaw pressure block 11 to crush the waste, when the movable jaw pressure block 27 is away from the fixed jaw pressure block 11, the synchronous plate 32 is driven to move through the bottom plate 31, and the inner wall of the limiting inclined groove 322 is used to squeeze the slide bar 331, thereby driving the extrusion plate 33 to move synchronously, and the movable grinding plate 333 is used to cooperate with the fixed grinding plate 34 to further squeeze the waste to assist in crushing. During the movement, the arc-shaped slider 35 is used to slide in the inner arc groove in the offset plate 36, thereby driving the inner plate 334 to repeatedly slide in the re-grinding groove 332, thereby achieving the introduction of shear force and torsional force through left and right activities in the auxiliary crushing process, thereby further enhancing the crushing effect.

[0019] In order to further solve the problem of residual waste inside the fixed jaw pressing block 11 and easy blockage of the crushing mouth, according to the embodiment of the present invention, Figures 1-10 As shown, a limit plate 321 is provided inside the crushing box 1, and a limit transverse groove 323 is provided on one side of the limit plate 321.

[0021] The movable groove 371 has a square outline, and the inner wall of the movable groove 371 is provided with an inclined surface. The inclined surface makes the inner wall of the movable groove 371 away from the movable jaw pressure block 27 tilt toward the groove. Through the setting of the movable groove 371, when the movable jaw pressure block 27 is away from the fixed jaw pressure block 11, the narrow groove corresponding to the inclined surface in the movable groove 371 is used to drive the column 38 to move left and right. When the movable jaw pressure block 27 is close to the fixed jaw pressure block 11, the column 38 moves in the wide groove of the movable groove 371. At this time, the movement of the side plate 37 will not drive the column 38 to move.

A squeezing plate 397 is fixedly connected to one side of the short plate 396. The squeezing plate 397 passes through the side of the fixed jaw pressure block 11 close to the movable jaw pressure block 27. The fixing frame 395 is fixedly connected to one side of the short plate 396. Through the arrangement of the mounting box 398, the short plate 396, the squeezing plate 397 and the fixing frame 395, when the notch groove 393 is closest to the fixing frame 395, the short plate 396 and the squeezing plate 397 are squeezed out from one side of the fixed jaw pressure block 11 to squeeze out the waste stuck inside the fixed jaw pressure block 11 to prevent the crushing mouth from being blocked.

[0024] A side groove 3981 is provided on one side of the installation box 398 , and the fixing frame 395 is slidably connected to the side groove 3981 . The setting of the side groove 3981 ensures a stable displacement effect of the fixing frame 395 .

[0025] A return spring 4 is fixedly connected between the extrusion plate 33 and the inner wall of the crushing box 1. Through the setting of the return spring 4, when the movable jaw pressure block 27 approaches the fixed jaw pressure block 11, the return spring 4 is used to assist the extrusion plate 33 in resetting.

A belt 25 is sleeved on the outside of the driving wheel 23 and the driving flywheel 24, and an eccentric roller is fixedly connected to the outside of the driving shaft 26. The eccentric roller is rotatably connected to the inside of the movable jaw pressure block 27. When the waste needs to be crushed, the motor 21 is turned on to drive the driving wheel 23 to rotate, and the transmission is carried out through the belt 25, thereby driving the driving flywheel 24 and the driving shaft 26 to rotate, so that the movable jaw pressure block 27 is used to cooperate with the fixed jaw pressure block 11 to achieve preliminary crushing work.

[0027] A hydraulic cylinder 12 is provided inside the crushing box 1, and a switching plate 13 is provided between the hydraulic cylinder 12 and one side of the movable jaw pressure block 27.

The stable operation of the movable jaw pressure block 27 is ensured by the arrangement of the hydraulic cylinder 12, the switching plate 13, the pull rod spring group 14 and the connecting plate 15.

[0028] Specifically, when it is necessary to crush the waste, the motor 21 is turned on to drive the driving wheel 23 to rotate, and the transmission is carried out through the belt 25, thereby driving the driving flywheel 24 and the driving shaft 26 to rotate, so that the movable jaw pressure block 27 cooperates with the fixed jaw pressure block 11 to achieve preliminary crushing work. In the process of the movable jaw pressure block 27 cooperating with the fixed jaw pressure block 11 to crush the waste, when the movable jaw pressure block 27 is away from the fixed jaw pressure block 11, the synchronous plate 32 is driven to move by the bottom plate 31, and the inner wall of the limiting inclined groove 322 is used to squeeze the slide bar 331, thereby driving the extrusion plate 33 to move synchronously. The setting of the limiting inclined groove 322 and the limiting transverse groove 323 ensures that the slide bar 331 moves stably horizontally when moving, and the movable grinding plate 333 cooperates with the fixed grinding plate 34 to further squeeze the waste to assist in crushing. During the movement of the extrusion plate 33, the arc-shaped slider 35 slides in the inner arc groove of the offset plate 36, thereby driving the inner plate 334 to repeatedly slide in the regrinding groove 332, thereby introducing shear force and torsional force through left and right movement during the auxiliary crushing process, further enhancing the crushing effect; During the left and right movement of the inner plate 334, the side plate 37 is driven to move synchronously, and the movable groove 371 is used to synchronously drive the column 38 and the cross plate 381 to move. When the mounting plate 391 moves back and forth horizontally, the movable frame 392 is driven to move synchronously. When the notch groove 393 is closest to the fixed frame 395, the connecting frame 394 is used to extrude the fixed frame 395. At the same time, the short plate 396 and the extrusion plate 397 are squeezed out from one side of the fixed jaw pressure block 11 to squeeze out the waste stuck inside the fixed jaw pressure block 11 to prevent the crushing mouth from being blocked.
