[0019] Embodiment: As Figures 1-5 shown, the present utility model provides a lithium battery pretreatment device under a protective gas system, including a base 1. One side of the top end of the base 1 is fixedly connected with four first support rods 8. The top ends of the four first support rods 8 are jointly fixedly connected with a crushing box 10. A feed inlet 4 is opened at the top end of the crushing box 10, and a feed pipe 5 is fixedly connected to the top end of the feed inlet 4. Two second support rods 7 are fixedly connected to the top end of the base 1. An intermittent conveying mechanism 3 is jointly arranged at the top ends of the two second support rods 7 and one side of the top end of the feed pipe 5. A crushing mechanism 2 is arranged at one end and inside the crushing box 10. The intermittent conveying mechanism 3 is used to facilitate the intermittent conveying of lithium batteries during pretreatment. The cooperation of the feed pipe 5 and the feed inlet 4 is used to facilitate the lithium batteries to be conveyed and fall into the crushing box 10 for crushing. The lithium batteries are double-crushed by the crushing mechanism 2 in the crushing box 10, thereby improving the processing effect of the pretreatment device.

[0020] The crushing mechanism 2 includes a long rod 26, and the long rod 26 is provided with four. One end of the four long rods 26 is rotatably connected to one end of the crushing box 10, and the outer surfaces of the four long rods 26 are fixedly sleeved with a crushing roller 27. One end of the four long rods 26 passes through the inner wall of one side of the crushing box 10, and the outer surfaces of the four long rods 26 are fixedly sleeved with a gear 25. The corresponding two gears 25 are meshed and connected, wherein one end of two of the long rods 26 is fixedly connected to a sprocket 21, and the outer surfaces of the two sprockets 21 are jointly sleeved with a chain 28. One end of the crushing box 10 is fixedly connected to a connecting shell 22, and the lower part of one end of the connecting shell 22 is fixedly connected to a support seat 24, and the top of the support seat 24 is fixedly connected to a first motor 23, and the first motor The output end of the machine 23 passes through one end of the connecting shell 22 and is fixedly connected to the middle of one end of one of the sprockets 21. The first motor 23 is started, and the output end of the first motor 23 drives one of the sprockets 21 to rotate. The rotation of one of the sprockets 21 cooperates with the chain 28 and the other sprocket 21 to make the other sprocket 21 rotate synchronously. The rotation of the two sprockets 21 drives two of the long rods 26 to rotate, and the rotation of the two long rods 26 drives two of the gears 25 to rotate. The rotation of the two gears 25 drives the other two gears 25 toward the opposite surfaces, so that the corresponding two crushing rollers 27 are driven toward the opposite surfaces to crush the lithium battery, achieving the effect of double crushing, thereby improving the treatment effect of the pretreatment device and avoiding the impact of incomplete crushing of the lithium battery on the environment.

[0021] The intermittent conveying mechanism 3 includes a connecting frame 34, the bottom end of the connecting frame 34 is fixedly connected to the two second support rods 7 and the top of the feed pipe 5, the inner walls on both sides of the connecting frame 34 are rotatably connected to two round rods 32, and the outer surfaces of the two round rods 32 are fixedly sleeved with pulleys 33, and the outer surfaces of the two pulleys 33 are jointly sleeved with a conveyor belt 31, one end of one of the round rods 32 is fixedly connected to a connecting rod 39, and the end of the connecting rod 39 facing away from the round rod 32 passes through the inner wall of one side of the connecting frame 34 and is fixedly connected to a groove plate 301, one end of the connecting frame 34 is fixedly connected to a support plate 37, and the top of the support plate 37 is fixedly connected to a second motor 38, the The output end of the second motor 38 is fixedly connected to the groove wheel 36 used in conjunction with the groove disk 301. When the second motor 38 is started, the output end of the second motor 38 drives the groove wheel 36 to rotate. The rotation of the groove wheel 36 cooperates with the groove disk 301 to make the groove disk 301 intermittent transmission. The intermittent transmission of the groove disk 301 drives the connecting rod 39 to rotate. The rotation of the connecting rod 39 drives one of the round rods 32 to rotate. The rotation of one of the round rods 32 drives one of the pulleys 33 to rotate. One of the pulleys 33 rotates intermittently to cooperate with the conveyor belt 31 and the other pulley 33, so that the conveyor belt 31 intermittently transports the lithium batteries, thereby avoiding the accumulation of lithium batteries during pretreatment, and indirectly improving the treatment efficiency of the pretreatment device.

[0022] A discharge hopper 9 is provided through the bottom end of the crushing box 10, and the discharge hopper 9 is inclined.

[0026] The outer surface of the conveyor belt 31 is tooth-shaped, and the conveyor belt 31 is inclined. The tooth shape is more convenient for conveying the lithium batteries.

[0027] Working principle: First, place the lithium batteries to be conveyed on the conveyor belt 31 of the intermittent conveying mechanism 3, and then start the second motor 38. The output end of the second motor 38 drives the sprocket 36 to rotate. The rotation of the sprocket 36 cooperates with the sprocket disc 301 to make the sprocket disc 301 drive intermittently.

[0029] The conveyed lithium batteries fall into the crushing box 10 through the cooperation of the feed pipe 5 and the feed port 4 for crushing. At the same time, the baffle 6 plays a protective role to prevent the conveyed lithium batteries from falling outside the feed pipe 5 when dropping;

[0030] Meanwhile, by activating the crushing mechanism 2 and starting the first motor 23, the output end of the first motor 23 drives one of the sprockets 21 to rotate. The rotation of one sprocket 21 in cooperation with the chain 28 and the other sprocket 21 causes the other sprocket 21 to rotate synchronously. The rotation of the two sprockets 21 drives the rotation of two of the long rods 26.

[0031] The rotation of two of the long rods 26 drives the rotation of two of the gears 25. The rotation of two of the gears 25 drives the other two gears 25 to transmit towards the opposite side, thereby realizing the transmission of two corresponding crushing rollers 27 towards the opposite side to crush the lithium battery, achieving the effect of double crushing of the lithium battery.

[0032] Then, the crushed lithium battery is discharged through the discharge hopper 9 for further processing.

[0033] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model.
