Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-6 , an embodiment provided by the utility model:

[0024] A crusher that is easy to replace cutters includes a crusher 1. The surface of the crusher 1 is provided with a shielding curtain 2 for preventing debris generated during the crushing process from splashing out. The surface of the crusher 1 is provided with a stepping motor 3 for driving a connecting roller 4 to rotate. The internal rotation of the crusher 1 is connected to the connecting roller 4 for connecting to a toothed cylinder 5. The surface of the connecting roller 4 is fixedly connected to a toothed cylinder 5 for sleeve-mounted hob 6. The surface of the toothed cylinder 5 is sleeved with the hob 6 for crushing. The surface of the hob 6 is provided with a toothed groove 7 for sleeve-mounted on the surface of the toothed cylinder 5. The surface of the connecting roller 4 is sleeved with a baffle 8 for abutting against the surface of the toothed cylinder 5 to prevent debris from splashing. The surface of the connecting roller 4 is sleeved with a limit sleeve 9 through a thread to limit the position of the baffle 8. The surface of the crusher 1 is provided with a movable groove 10 for the movable rod 11 to move. The movable groove 10 is internally connected to the movable rod 11 for driving the connecting rod 12 to move. The surface of the movable rod 11 is fixedly connected to the connecting rod 12 for connecting the movable rod 11 and the plug-in cylinder 14. The surface of the connecting rod 12 is fixedly connected to the fixed plate 13. The connecting fixing bolt 16 fixes the position of the plug-in cylinder 14. The end of the connecting rod 12 away from the movable rod 11 is fixedly connected to the plug-in cylinder 14 for plugging into the surface of the connecting roller 4. The surface of the plug-in cylinder 14 is fixedly connected to the plug-in rod 15 for plugging into the slot on the surface of the connecting roller 4. While limiting the position of the hob 6, the hob 6 can rotate normally. The surface of the fixed plate 13 is connected with a fixing bolt 16 through a threaded sleeve for fixing the position of the plug-in cylinder 14. The surface of the crusher 1 is rotatably connected to a protective door 17 for protecting the inside of the crusher 1. The surface of the protective door 17 is rotatably connected to a rotating lock buckle 18 for being inserted into the connecting lock buckle 19. The surface of the crusher 1 is fixedly connected to a connecting lock buckle 19 for connecting the rotating lock buckle 18 and the rotating block 22. The surface of the crusher 1 is fixedly connected to a fixing rod 20 for connecting the limiting piece 21 while ensuring the normal rotation of the rotating block 22. The surface of the fixing rod 20 is fixedly connected to the limiting piece 21 for limiting the position of the rotating block 22. The surface of the fixing rod 20 is rotatably connected to the rotating block 22 for being inserted into the surface of the connecting lock buckle 19.

[0025] Furthermore, a slot is provided on the surface of the connecting roller 4 for inserting the connecting rod 15, a threaded groove is provided on the surface of the connecting roller 4, a first circular groove is provided on the surface of the baffle 8, and a second circular groove is provided on the surface of the limiting sleeve 9. By pressing the baffle 8 against the surface of the hob 6 and then tightening the limiting sleeve 9 on the other side of the baffle 8, the position of the baffle 8 is limited.

[0026] Furthermore, the baffle 8 is connected to the surface of the toothed cylinder 5 through the limiting sleeve 9, and the hob 6 is connected to the surface of the toothed cylinder 5 through the toothed groove 7. The special shape of the toothed cylinder 5 and the toothed groove 7 make it difficult for the hob 6 to fall off after being inserted into the surface of the toothed cylinder 5. The setting of the baffle 8 prevents the hob 6 from falling off the surface of the toothed cylinder 5.

[0027] Furthermore, the movable rod 11 is movably connected to the inside of the crusher 1 through the movable groove 10, and the connecting rod 12 is rotatably connected to the surface of the crusher 1 through the movable rod 11. The movable connecting rod 12 drives the movable rod 11 to move in the movable groove 10, and then can rotate close to the surface of the crusher 1.

[0028] Furthermore, the plug-in cylinder 14 is movably connected to the inside of the crusher 1 through the connecting rod 12, the plug-in rod 15 is plug-in connected to the slot on the surface of the connecting roller 4 through the plug-in cylinder 14, the fixed plate 13 is fixedly connected to the inside of the crusher 1 through the fixing bolt 16, and the movable rod 11 is fixedly connected to the inside of the crusher 1 through the fixing bolt 16. Move the plug-in cylinder 14, insert the plug-in cylinder 14 into the surface of the connecting roller 4, and then fix the position of the fixed plate 13 with the fixing bolt 16.

[0029] Furthermore, a first through groove is provided on the surface of the rotating lock buckle 18, and the rotating lock buckle 18 is plugged into and connected to the surface of the protective door 17 and the connecting lock buckle 19. A second through groove is provided on the surface of the connecting lock buckle 19, and the rotating block 22 is plugged into and connected to the surface of the connecting lock buckle 19 through the fixing rod 20. Rotating the rotating lock buckle 18 can insert the rotating lock buckle 18 into the surface of the connecting lock buckle 19, and then rotating the rotating block 22 can insert the rotating block 22 into the second through groove on the surface of the connecting lock buckle 19 to fix the position of the rotating lock buckle 18.

[0030] Furthermore, the rotating block 22 is connected by the surface of the connecting lock buckle 19 and the rotating lock buckle 18, and the rotating lock buckle 18 is fixedly connected by the rotating block 22 and the surface of the connecting lock buckle 19. The protective door 17 is fixedly connected to the surface of the crusher 1 through the rotating lock buckle 18. Rotating the rotating lock buckle 18 can insert the rotating lock buckle 18 into the surface of the connecting lock buckle 19, and then rotating the rotating block 22 to insert the rotating block 22 into the second through groove on the surface of the connecting lock buckle 19 to fix the position of the rotating lock buckle 18, thereby fixing the position of the protective door 17.

[0031] Working principle: When the crusher 1 is in use, the objects to be crushed can be placed in the crusher 1. If the internal cutter of the crusher 1 needs to be replaced, the rotating block 22 can be rotated to make the rotating block 22 leave the surface of the connecting lock 19, and then the rotating lock 18 can be rotated to make the rotating lock 18 leave the surface of the connecting lock 19. Then the protective door 17 can be opened, the fixing bolts 16 on the surface of the fixing plate 13 can be screwed out, and the connecting rod 12 can be moved to the surface of the crusher 1 so that the plug-in cylinder 14 leaves the surface of the connecting roller 4. Rotate the connecting rod 12 so that the connecting rod 12 is perpendicular to the surface of the crusher 1, and then unscrew the limit sleeve 9, remove the baffle 8, and remove the roller 6 from the surface of the toothed cylinder 5 for replacement. After replacement, install the baffle 8 and the limit sleeve 9 back to their original position, rotate the connecting rod 12 to move the connecting rod 12, so that the plug-in cylinder 14 and the plug-in rod 15 are plugged into the surface of the connecting roller 4, and then close the protective door 17, rotate the rotating lock 18 to plug it into the surface of the connecting lock 19, and then rotate the rotating block 22 to plug it into the second through groove on the surface of the connecting lock 19.
