[0055] The outer disk 4037 is rotatably sleeved through the rotation groove 4039 and the limit groove 4032, and the limit steel column 4035 is clamped with the limit slot 4038. Through the design of the inclined portion of the limit slot 4038, when the rotating disk 4031 drives the limit steel column 4035 to rotate clockwise through the sliding groove 4033, the limit steel column 4035 and the arc portion of the limit slot 4038 are clamped, so that the rotating disk 4031 and the outer disk 4037 cannot rotate.

[0057] One end of the limiting shaft 410 is rotatably connected to the bottom of the extrusion frame 401 close to the side of the buffer dust suppression component 7, and the other end of the limiting shaft 410 is fixedly assembled with a fixing bolt 412.

[0058] In a preferred embodiment: the one-way ratchet 403 includes a rotating disk 4031, and limiting grooves 4032 are provided on the outer edges of both sides of the rotating disk 4031, and sliding grooves 4033 are provided on the outer walls of the limiting grooves 4032. A spring 2 4034 is fixedly installed on the sliding groove 4033 near the axis of the rotating disk 4031, and a limiting steel column 4035 is provided on the sliding groove 4033 away from the axis of the rotating disk 4031.

A limiting clamping groove 4038 is annularly provided on the inner wall of the outer disk 4037. A rotating groove 4039 is provided on the inner wall of the limiting clamping groove 4038, and a rotating column 40310 is rotatably embedded on the outer wall of the convex tooth portion of the outer wall of the outer disk 4037;

[0059] The outer disk 4037 is rotatably sleeved through the rotating groove 4039 and the limiting groove 4032, the rotating disk 4031 and the axis of the eccentric shaft 402 are fixedly assembled, and the convex tooth part of the outer wall of the outer disk 4037 is meshed with the meshing teeth 308.

[0060] In the above structure, the outer disk 4037 is rotatably sleeved through the rotating groove 4039 and the limiting groove 4032, and the limiting steel column 4035 is clamped with the limiting clamping groove 4038. Through the design of the inclined portion of the limiting clamping groove 4038, when the rotating disk 4031 drives the limiting steel column 4035 to rotate clockwise through the sliding groove 4033, the limiting steel column 4035 and the arc portion of the limiting clamping groove 4038 are clamped, so that the rotating disk 4031 and the outer disk 4037 cannot rotate. However, through the design of the inclined portion of the limiting clamping groove 4038, when the rotating disk 4031 drives the limiting steel column 4035 to rotate counterclockwise through the sliding groove 4033, the limiting steel column 4035 moves to one side of the axis of the rotating disk 4031 through the guide of the limiting clamping groove 4038, thereby realizing the rotation between the rotating disk 4031 and the outer disk 4037.

[0061] By fixing the turntable 4031 and the eccentric shaft 1 402 on their axes, the convex tooth portion of the outer wall of the outer disk 4037 meshes with the teeth 308, so that when the extrusion frame 401 moves toward the side of the buffer dust reduction assembly 7 through the eccentric shaft 2 404, the turntable 4031 and the outer disk 4037 can rotate, and when the extrusion frame 401 moves toward the side away from the buffer dust reduction assembly 7 through the eccentric shaft 2 404, the turntable 4031 and the outer disk 4037 cannot rotate, thereby causing the one-way ratchet 403 to drive the eccentric shaft 1 402 to rotate, thereby achieving further driving action on the eccentric shaft 1 402.

[0062] In a preferred embodiment, the extrusion plate 409 includes an extrusion plate body 4091, a spacing groove 4092 is provided on the bottom outer wall of the extrusion plate body 4091, a shaft groove 4093 is provided on the outer wall of the spacing groove 4092, an arc groove 4094 is provided on the outer wall of the spacing groove 4092, a mounting groove 4095 is provided on one side outer wall of the extrusion plate body 4091, a connecting shaft 4096 is rotatably connected to the inner wall of the shaft groove 4093, and the connecting shaft 4096 is close to the outer wall of the mounting groove 4095. An extrusion block 4097 is fixedly assembled, and a return spring 40910 is fixedly assembled on one side of the extrusion block 4097 close to the extrusion frame 401. The inner wall of the spacing groove 4092 is provided with a plurality of sets of sleeve discs 4098 fixedly assembled with the connecting shaft 4096, and a connecting shaft slidably sleeved with the arc groove 4094 is penetrated between the plurality of sleeve discs 4098. A push block 4099 is arranged on one side of the sleeve disc 4098 close to the vertical plate 301, and a telescoping device is inlaid on one side of the push block 4099 close to the vertical plate 301;

[0063] The connecting shaft 4096 and the sleeve plate 4098 are eccentrically arranged, and are fixedly assembled with the telescopic device and the vertical plate 301 embedded in the inner wall of the push block 4099.

[0064] In the above structure, the push block 4099 is pushed by the telescopic device embedded in the inner wall of the push block 4099, so that a plurality of socket plates 4098 are rotated with the shaft groove 4093 as the axis through the connecting shaft 4096, and the eccentric setting of the connecting shaft 4096 and the socket plate 4098 makes the rotation angle of the socket plate 4098 different, thereby realizing the change of the distance between the socket plate 4098 and the extrusion plate 1 408, and then realizing the change of the gap between the extrusion plate 1 408 and the extrusion plate 2 409.

[0065] In a preferred embodiment: the buffer dust reduction assembly 7 includes a water tank 701 and a buffer box 702, a buffer tank 703 is provided on the side of the buffer box 702 away from the water tank 701, a dust reduction water pipe 704 is fixedly mounted on the side of the buffer box 702 close to the water tank 701, a buffer card slot 706 is provided at the bottom of the buffer box 702, a push block 705 is slidably sleeved on the inner wall of the buffer tank 703, the push block 705 and the connecting plate 407 are rotatably engaged, and the inner cavity of the buffer tank 703 is connected to the inner cavity of the water tank 701 through a hose;

[0066] A first one-way valve is provided at the connection point between the buffer tank 703 and the water tank 701 , and a second one-way valve is provided at the connection point between the buffer tank 703 and the dust suppression water pipe 704 .

[0067] In the above structure, the eccentric shaft 2 404 and the extrusion frame 401 are rotatably sleeved, and the driving wheel 5 drives the eccentric shaft 2 404 to rotate, so that the extrusion frame 401 moves along the rotation path of the eccentric shaft 2 404, and then the extrusion frame 401 moves toward the vertical plate 301 to reciprocate;

[0068] Then, the extrusion frame 401 drives the push block 2 705 located on the inner wall of the buffer groove 703 to move back and forth through the connecting plate 407, and a first one-way valve is provided at the connection between the buffer groove 703 and the water tank 701, and a second one-way valve is provided at the connection between the buffer groove 703 and the dust reduction water pipe 704, so that when the push block 2 705 moves toward the extrusion frame 401, the first one-way valve opens, and the liquid located in the inner cavity of the water tank 701 moves to the inner cavity of the buffer groove 703, and when the push block 2 705 moves away from the extrusion frame 401, the second one-way valve opens, and the liquid located in the inner cavity of the buffer groove 703 is discharged through the dust reduction water pipe 704, thereby realizing the dust reduction operation.

[0069] Working principle: the driving wheel 5 drives the eccentric shaft 2 404 to rotate, so that the extrusion frame 401 moves along the rotation path of the eccentric shaft 2 404, and then the extrusion frame 401 moves toward the vertical plate 301 to reciprocate, and the eccentric shaft 1 402 is set in the inner cavity of the extrusion frame 401;

[0070] At the same time, when the extrusion frame 401 reciprocates through the eccentric shaft 2 404, the end of the extrusion frame 401 close to the one-way ratchet 403 also reciprocates at the same time;

[0071] When the extrusion frame 401 drives the one-way ratchet 403 to reciprocate, the one-way ratchet 403 meshes with the teeth 308 through the convex teeth on the outer wall of the outer disc 4037;

[0072] At the same time, the one-way ratchet 403 is sleeved through the second moving groove 307, and the outer wall of the outer plate 4037 is used to rotate the embedded rotating column 40310, so that the top of the one-way ratchet 403 and the top inner wall of the second moving groove 307 slide against each other, and the rotating column 40310 can reduce the friction between the second moving groove 307 and the one-way ratchet 403;

[0073] By designing the inclined portion of the limiting card slot 4038, when the extrusion frame 401 drives the one-way ratchet 403 to move away from the vertical plate 301, the rotating disk 4031 drives the limiting steel column 4035 to rotate counterclockwise through the sliding slot 4033, and the limiting steel column 4035 moves toward the axis of the rotating disk 4031 through the guide of the limiting card slot 4038, thereby realizing the rotation between the rotating disk 4031 and the outer disk 4037;

[0074] When the extrusion frame 401 drives the one-way ratchet 403 to move toward the side of the vertical plate 301, the outer disk 4037 and the rotating disk 4031 are engaged with each other through the limiting steel column 4035 and the arc-shaped portion of the limiting slot 4038, so that the rotating disk 4031 and the outer disk 4037 cannot rotate, thereby making the one-way ratchet 403 drive the eccentric shaft 1 402 to rotate;

[0075] At the same time, since the extrusion frame 401 moves along the rotation path of the second eccentric shaft 404, the extrusion frame 401 drives the one-way ratchet 403 to move left and right and up and down, and then the extrusion frame 401 drives the one-way ratchet 403 to drive the rotating frame 306 to rotate around the shaft body 305 through the second moving groove 307;

[0076] Thus, the material between the extrusion plate 1 408 and the extrusion plate 2 409 is crushed by the extrusion of the extrusion plate 1 408 and the extrusion plate 2 409.

[0077] The push block 1 4099 is pushed by the telescopic device embedded in the inner wall of the push block 1 4099, so that the plurality of sleeve disks 4098 are rotated with the rotating shaft groove 4093 as the axis through the connecting shaft 4096, so as to change the distance between the sleeve disk 4098 and the extrusion plate 1 408, and then change the gap between the extrusion plate 1 408 and the extrusion plate 2 409, so as to achieve the crushing adjustment of different particle sizes;

[0078] At the same time, the extrusion frame 401 drives the push block 2 705 located on the inner wall of the buffer groove 703 to move back and forth through the connecting plate 407, and a first one-way valve is provided at the connection between the buffer groove 703 and the water tank 701, and a second one-way valve is provided at the connection between the buffer groove 703 and the dust reduction water pipe 704, so that when the push block 2 705 moves toward the extrusion frame 401, the first one-way valve opens, and the liquid located in the inner cavity of the water tank 701 moves to the inner cavity of the buffer groove 703, and when the push block 2 705 moves away from the extrusion frame 401, the second one-way valve opens, and the liquid located in the inner cavity of the buffer groove 703 is discharged through the dust reduction water pipe 704, thereby realizing the dust reduction operation.
