[0037] Reference Figure 2 and Figure 3 The crushing assembly 1 includes a crushing roller 11. The inner cross section of the shell 5 is circular. The crushing roller 11 is rotatably arranged in the shell 5, and the rotation axis of the crushing roller 11 is coaxially arranged with the center line of the shell 5. The driving assembly 4 is connected to the crushing roller 11. The side of the crushing roller 11 is provided with a crushing part 111 that makes the side of the crushing roller 11 convex. The crushing part 111 is arranged along the length direction of the crushing roller 11. The driving assembly 4 drives the crushing roller 11 to rotate, and the crushing roller 11 drives the crushing part 111 to rotate. When the crushing part 111 rotates, it cooperates with the inner wall of the shell 5 to squeeze the material, thereby crushing the material.

[0038] Reference Figures 3 to 5 The grinding assembly 2 includes a grinding roller 21, an extrusion block 22 and a control member 23. The grinding roller 21 is arranged on one side of the crushing roller 11, and the grinding roller 21 rotates with the crushing roller 11. At the same time, the grinding roller 21 is arranged to rotate around its own center line. A grinding groove 6 is opened on the side of the crushing roller 11. The grinding groove 6 is arranged in an arc shape. The side of the grinding roller 21 extends into the grinding groove 6. The gap between the grinding roller 21 and the grinding groove 6 gradually decreases around the rotation direction of the grinding roller 21, so that the grinding roller 21 cooperates with the side wall of the grinding groove 6 to grind the material when rotating. There are multiple groups of extrusion blocks 22, and the multiple groups of extrusion blocks 22 are arranged at intervals around the grinding roller 21. Each multiple extrusion blocks 22 are arranged as one group, and the multiple extrusion blocks 22 are arranged at intervals along the length direction of the grinding roller 21.

After the material is crushed by the crushing part 111, the crushed particles enter the grinding roller 21 through the through hole 71. As the grinding roller 21 rotates, the baffle 28 rotates to an inclined upward side away from the crushing roller 11. Figure 4The middle baffle plate 28 is in an upward tilted state, and the materials between the grinding roller 21 and the baffle plate 28 will be gathered into the grinding groove 6. The extrusion block 22 drives the materials into the gap between the grinding roller 21 and the grinding groove 6 for grinding as the grinding roller 21 rotates. At the same time, the extrusion block 22 gradually slides toward the inside of the grinding roller 21 during grinding, that is, the extrusion block 22 is in contact with the side wall of the grinding groove 6 during grinding. After the grinding is completed, the control member 23 drives the extrusion block 22 to move back and forth on the grinding roller 21 to remove part of the materials adhering to the grinding roller 21.

[0040] Reference Figures 3 to 5 At the same time, as the extrusion block 22 moves back and forth, part of the material adhering to the grinding roller 21 is removed, driving the material on the side of the grinding roller 21 to reciprocate and collide between the grinding roller 21 and the shell 5. The remaining material adhering to the grinding roller 21 can be removed during the reciprocating collision, and the clumped material can be broken up during the collision process, which is convenient for subsequent discharge.

[0043] Reference Figures 3 to 5, the spring 1 233 drives the push rod 232 to keep in contact with the side of the control rod 231. During grinding, the push rod 232 moves to the retracting portion 3. At the same time, under the action of the spring 1 233, the extrusion block 22 gradually moves into the grinding roller 21. The extrusion block 22 keeps in contact with the inner wall of the grinding groove 6 during the process of moving into the grinding groove 6, so as to push the material at the edge of the grinding groove 6 into the grinding groove 6 for grinding. After the grinding is completed, the push rod 232 moves to the corrugated groove 31. As the grinding roller 21 continues to rotate, the push rod 232 reciprocates on the grinding roller 21, thereby adjusting the position of the extrusion block 22.

[0044] Reference Figures 3 to 5 Every two adjacent groups of extrusion blocks 22 are staggered, that is, the extrusion blocks 22 correspond to the gaps between two adjacent extrusion blocks 22 in an adjacent group, so that the extrusion blocks 22 can cover the grinding grooves 6 when rotating with the grinding roller 21, thereby reducing the phenomenon of missing materials during grinding.

[0045] Reference Figures 3 to 5 , baffle 1 7 and baffle 2 8 are provided in two groups, and crushing part 111 and grinding roller 21 are also provided in two groups, and the two groups of grinding roller 21 are symmetrically arranged around the axis center of crushing roller 11.

The control rod 231 is fixedly connected to the turntable 42, the gear ring 43 is fixedly arranged in the housing 5, and the gear ring 43 is arranged on the side of the turntable 42 away from the crushing roller 11. The gear 44 is coaxially arranged at the end of the grinding roller 21, and the gear 44 is meshed with the gear ring 43. The power piece 41 is set as a motor, and the output end of the power piece 41 is connected to the rotating shaft of the crushing roller 11 to drive the crushing roller 11 to rotate.

[0047] Reference Figure 1 and Figure 6The output end of the power member 41 includes a belt 411 and a pulley 412.
