The crankshaft 11 is fixedly connected to the output end of the rotating motor 10, and the crankshaft 11 is movably and rotatably connected to the inner wall of the equipment housing 1. Example 2

[0027] Based on the above Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 The crushing assembly includes a rotating shaft 12, a driving motor 13 is installed on one side surface of the equipment housing 1, crushing teeth 14 are installed on the outer surface of the rotating shaft 12, a driving gear 15 is installed on the outer surface of the rotating shaft 12, and the rotating shaft 12 is installed on the inner wall of the equipment housing 1.

[0028] There are two rotating shafts 12, which are equidistantly distributed on the inner wall of the device housing 1. The rotating shafts 12 are movably and rotatably connected to the device housing 1. One end of one of the rotating shafts 12 is connected to the output end of the drive motor 13. A driving gear 15 is correspondingly distributed on the outer surface of each rotating shaft 12. The two driving gears 15 are meshed with each other. A number of crushing teeth 14 are correspondingly distributed on the outer surface of each rotating shaft 12.

[0029] The extrusion assembly includes two extrusion shafts 16, which are equidistantly distributed on the inner wall of the device housing 1. The extrusion shafts 16 are movably and rotatably connected to the device housing 1. A transmission gear 17 is correspondingly distributed on the outer surface of each extrusion shaft 16, and each transmission gear 17 is respectively engaged with a drive gear 15.

[0030] The working principle and usage process of the present invention are as follows: when the lithium battery negative electrode material crushing device is needed, the drive motor 13 and the rotating motor 10 are started at the same time. When crushing is required, the lithium battery is put into the feed trough 2 opened on the top surface of the device housing 1. When the lithium battery is put into the feed trough 2, the started drive motor 13 will drive the rotating shaft 12 connected to its output end to rotate, and the outer surface of the rotating shaft 12 is installed with a drive gear 15, and the drive gear 15 and the other drive gear 15 are meshed with each other, so when the drive motor 13 drives the rotating shaft 12 and the drive gear 15 to rotate, the other rotating shaft 12 and the drive gear 15 will be driven to rotate through the drive gear 15, and the outer surfaces of the two drive gears 15 are respectively meshed with transmission gears 17. When the two drive gears 15 rotate, they will respectively drive the two The transmission gear 17 and the extrusion shaft 16 rotate. When the lithium battery is put into the feed trough 2, the lithium battery will contact the two rotating extrusion shafts 16. At this time, the two rotating extrusion shafts 16 will initially squeeze the lithium battery, so that the graphite in the lithium battery is squeezed and crushed. After the lithium battery is squeezed by the two extrusion shafts 16, the squeezed lithium battery will fall between the two rotating shafts 12. The outer surface of the rotating shaft 12 is installed with crushing teeth 14 and the rotating shaft 12 is driven by the driving motor 13 to rotate on the inner wall of the equipment housing 1. Therefore, the rotating shaft 12 will drive the crushing teeth 14 installed on its outer surface to rotate. When the lithium battery falls between the two rotating shafts 12, it will contact the crushing teeth 14 installed on the outer surface of the rotating shaft 12. At this time, the lithium battery is crushed and torn by the rotation of the crushing teeth 14, thereby achieving a crushing effect.

[0031] When the lithium battery is broken, it will fall on the top surface of the inclined plate 6, and the inclined plate 6 itself has a certain inclination angle, so when the lithium battery falls on the surface of the inclined plate 6, it will slide along its surface. When the lithium battery slides from the surface of the inclined plate 6, it will fall on the top surface of the screening plate 8. Because the bottom surface of the screening plate 8 is equipped with a transmission rod 9, and the transmission rod 9 is movably rotated with the crankshaft 11, when the rotating motor 10 is started, it will drive the crankshaft 11 installed at its output end to rotate, so the rotating crankshaft 11 will cause the height of the transmission rod 9 to change, and the transmission rod 9 is movably rotated with the screening plate 8. When the height of the transmission rod 9 changes, the height of the screening plate 8 will be changed. The degree of separation changes, and the continuous rotation of the crankshaft 11 causes the screening plate 8 to continuously move up and down on the inner wall of the limiting ring 7, generating a vibration effect. Because the top surface of the screening plate 8 is provided with holes, the continuously vibrating screening plate 8 will drive the crushed lithium batteries on its surface to vibrate, and the copper foil and the graphite are separated from each other through the vibration. At this time, the separated graphite will fall into the storage box 5 through the holes on the surface of the screening plate 8 due to its smaller volume, and the separated graphite will be collected by the storage box 5, while the copper foil will slide from the surface of the screening plate 8 with the vibration due to its larger volume, and finally be discharged from the inner wall of the discharge trough 3, thereby realizing the crushing of the lithium batteries and the classified collection of materials.
