[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-4This utility model provides a crusher for recycling waste batteries, including a frame 7. A secondary crushing shell 5 is bolted to the top of the frame 7. A connecting shell 4 is welded to the top of the secondary crushing shell 5, and a primary crushing shell 1 is welded to the top of the connecting shell 4. Two crushing rollers 17 for pre-crushing the batteries are rotatably connected to the primary crushing shell 1 via bearings. Crushing blades 20 for secondary crushing of the batteries are rotatably connected to the secondary crushing shell 5 via bearings. A drive assembly for driving the two crushing rollers 17 and the crushing blades 20 is provided on one side of the frame 7. Inert gas injection assemblies are provided inside the primary crushing shell 1 and the secondary crushing shell 5. A discharge assembly is provided, which drives two crushing rollers 17 inside the primary crushing housing 1 to pre-crush the battery. The pre-crushed battery falls from the connecting housing 4 into the secondary crushing housing 5. At the same time, the drive assembly drives the crushing blades 20 inside the secondary crushing housing 5 to perform secondary crushing on the pre-crushed battery. However, since the oxygen content in the air is high, the battery is prone to explosion during the crushing process. Therefore, in the multi-stage crushing process, an inert gas, such as nitrogen, needs to be injected into the housing through an inert gas injection assembly to reduce the oxygen content in the air to ≤2%, thereby reducing the risk of explosion.

[0025] In this invention, the drive assembly includes a motor 8 fixed to one side of the frame 7 by bolts. One end of the output shaft of the motor 8 is keyed to a drive pulley 12. One end of each of the two crushing rollers 17 passes through the primary crushing housing 1 and is keyed to two meshing drive gears 3. The other end of one of the crushing rollers 17 passes through the primary crushing housing 1 and is keyed to a driven pulley 10. One end of the crushing blade 20 passes through the secondary crushing housing 5 and is keyed to a multi-stage pulley 11 that is connected to the drive pulley 12 and the driven pulley 10 via belt drive. When the motor 8 is started, the motor 8 rotates, causing the drive pulley 12 to drive the multi-stage pulley 11 to rotate via the belt. The rotation of the multi-stage pulley 11 drives the driven pulley 10 to rotate via the belt. The rotation of the driven pulley 10 drives one of the crushing rollers 17 to rotate. At the same time, the two crushing rollers 17 rotate inward simultaneously through the meshing drive gears 3, crushing the waste batteries. Meanwhile, the rotation of the multi-stage pulley 11 drives the crushing blade 20 to perform secondary crushing of the crushed waste batteries.

[0026] In this invention, the discharge assembly includes two arc-shaped plates 23 rotatably connected to the secondary crushing housing 5 via bearings. The bottom ends of the two arc-shaped plates 23 are aligned and contact each other. One end of each arc-shaped plate 23 passes through the secondary crushing housing 5 and is keyed to a reversing gear 25. A finger cylinder 24 is bolted to one side of the outer wall of the secondary crushing housing 5. The two clamping arms of the finger cylinder 24 are respectively bolted to racks 26 that mesh with the two reversing gears 25. A collection box 6 is provided inside the frame 7, and the collection box 6 is located below the secondary crushing housing 5. The lower port of the secondary crushing shell 5 is sealed by two arc-shaped plates 23, which facilitates the injection of inert gas and also facilitates the secondary crushing of the crushed waste battery material by the crushing blade 20. When opening, the finger cylinder 24 is activated and moves outward through the clamping arm, which drives the rack 26 to move outward. Then, the rack 26 drives the flipping gear 25 and drives the two arc-shaped plates 23 to flip downward, thereby opening the bottom of the secondary crushing shell 5 and allowing the crushed battery material to enter the collection box 6.

[0027] In this invention, the inert gas injection assembly includes a baffle 21 fixed to the inner wall of one side of the secondary crushing shell 5 by bolts. The secondary crushing shell 5 and the primary crushing shell 1 are respectively welded to one side with an outlet pipe 22 and an inlet pipe 18. The top of the primary crushing shell 1 is provided with a sealing mechanism, which includes a cover plate 9 hinged to the top of the primary crushing shell 1. Both outer walls of the primary crushing shell 1 are rotatably connected with opening cylinders 2, and one end of the piston rod of the opening cylinder 2 is rotatably connected to the cover plate 9. The opening cylinder 2 shortens to make the cover plate 9 flip downward and close the top opening of the primary crushing shell 1. After the closure is completed, the outlet pipe 22 and the inlet pipe 18 are connected to the external inert gas tank, and the inert gas is injected into the cavity formed after the primary crushing shell 1, the connecting shell 4 and the secondary crushing shell 5 are closed, and the original air is squeezed out from the outlet pipe 22, thereby completing the replacement of the air inside the closed cavity.

[0028] In this invention, a rotating shaft 15 is rotatably connected inside the secondary crushing housing 5 via bearings. A guide plate 19 is fixed to one side of the rotating shaft 15 by bolts. The bottom end of the guide plate 19 extends above the crushing blade 20. One end of the rotating shaft 15 passes through the secondary crushing housing 5 and is fitted with a torsion spring 16. Both ends of the torsion spring 16 are fixed to the rotating shaft 15 and the secondary crushing housing 5, respectively. A force plate 14 is fixed to one end of the rotating shaft 15 by bolts. A lever 13 that can contact the force plate 14 is fixed to one side of the multi-stage pulley 11 by bolts. The multi-stage pulley 11 drives the lever 13 to rotate and intermittently presses and pushes the force plate 14. Under the action of the torsion spring 16, the force plate 14 drives the rotating shaft 15 and the guide plate 19 to swing up and down, thereby preventing material from accumulating on the guide plate 19.

[0029] The use of this utility model involves the following steps:

[0030] S1: Then, waste batteries are placed from the top of the primary crushing shell 1. The cover plate 9 is flipped downwards and closed by the shortening of the cover opening cylinder 2. The lower port of the secondary crushing shell 5 is closed by the two arc-shaped plates 23.

[0031] S2: After sealing, connect the outlet pipe 22 and the inlet pipe 18 to the external inert gas tank respectively, and inject inert gas into the chamber formed after sealing the primary crushing shell 1, the connecting shell 4 and the secondary crushing shell 5, and squeeze out the original air from the outlet pipe 22, thereby completing the replacement of the air inside the sealed chamber.

[0032] S3: Then, by starting the motor 8, the motor 8 rotates, causing the drive pulley 12 to drive the multi-stage pulley 11 to rotate via the belt. The multi-stage pulley 11 rotates, causing the driven pulley 10 to rotate via the belt. The driven pulley 10 rotates, causing one of the crushing rollers 17 to rotate. At the same time, the two meshing drive gears 3 make the two crushing rollers 17 rotate inward at the same time, and crush the waste batteries.

[0033] S4: The crushed waste batteries fall into the secondary crushing shell 5 through the connecting shell 4 and the guide plate 19, and the crushing blades 20 are driven by the multi-stage pulleys 11 to perform secondary crushing of the crushed waste batteries.

[0034] S5: At the same time, the multi-stage pulley 11 drives the lever 13 to rotate and intermittently squeezes and pushes the force plate 14. Under the action of the torsion spring 16, the force plate 14 drives the rotating shaft 15 and the guide plate 19 to swing up and down, thereby avoiding the accumulation of materials on the guide plate 19.

[0035] S6: After crushing is completed, the finger cylinder 24 is activated and the finger cylinder 24 moves outward through the clamping arm, which drives the rack 26 to move outward. Then the rack 26 drives the flipping gear 25 to rotate and drives the two arc plates 23 to flip downward, thereby opening the bottom of the secondary crushing shell 5 and allowing the crushed battery material to enter the collection box 6.
