[0046] The conversion box 14 is also provided with a cavity, and a partition plate 23 is sealed and fixedly installed in the middle position of the conversion box 14. The conversion box 14 is slidably provided with two movable plates 24, and the two movable plates 24 are respectively located on both sides of the partition plate 23; the partition plate 23 is provided to set the conversion box 14 into two sections, one for storing a protective gas (such as nitrogen) during crushing, and the other for storing the air in the machine body 1 after being extracted.

The elastic pad 26 can be made of rubber material.

[0048] The two ends of the conversion box 14 are rotatably mounted with a rotating disk 28 (the rotating disk 28 is rotatably sealed and arranged on the conversion box 14, and the rotating disk 28 penetrates the conversion box 14), and a control moving member is arranged between the rotating disk 28 and the corresponding moving plate 24.

The driving end of the energy-saving motor 19 is fixedly installed with the shaft 20. One end of the shaft 20 is rotatably installed in the control box 17. The shaft 20 is fixedly connected to the baffle plate 21.

[0050] Reference Figure 1-10 The control moving component includes a magnetic block 27 and a magnetic block 29. The sides of the two rotating disks 28 that are close to each other are both circumferentially fixedly installed with multiple magnetic blocks 29. The sides of the two moving plates 24 that are far away from each other are both fixedly installed with multiple magnetic blocks 27 that cooperate with the magnetic block 29. The magnetism of the two adjacent magnetic blocks 27 on the same vertical plane is opposite. The number of magnetic blocks 29 on a single rotating disk 28 is an even number, and the magnetism of the two adjacent magnetic blocks 29 on the same side is opposite. By using the combination of magnetic blocks 1 27 and magnetic blocks 2 29, the reciprocating movement of the moving plate 24 in the conversion box can be controlled.

[0051] The intermittent rotating component includes a cover 30, a motor 31, a shaft 32, a transmission shaft 2 33, a gear set 2 34, a gear 1 35, a gear 2 36, a rotating shaft 37, a transmission structure 2 38, and a shaft 39. A shaft 39 is fixedly installed on the side away from each other of the two turntables 28. The cover 30 is fixedly installed on the outside of the conversion box 14. The motor 31 is fixedly installed in the cover 30. The driving end of the motor 31 is fixedly installed with the shaft 32. A transmission shaft 2 33 and two rotating shafts 37 are rotatably mounted on the cover body 30; a gear set 2 34 is installed between the shaft 32 and the transmission shaft 2 33, and two gears 1 35 are installed on the transmission shaft 2 33 through two one-way bearings, and the self-locking directions of the two one-way bearings are opposite; a gear 2 36 meshing with the corresponding gear 1 35 is fixedly mounted on the two rotating shafts 37, and one end of the two rotating shafts 37 rotates through the cover body 30 and a transmission structure 2 38 is sleeved between the corresponding shaft body 39.

[0052] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0053] In the present invention, the charged lithium batteries to be crushed are poured into the body 1 through the feed seat 4, and then the feed seat 4 is closed and the vacuum pump 15 is started. The vacuum pump 15 works to extract the gas in the crushing interval 6 through the circular tube, and then transports it to the air storage interval (storage air) through the outlet pipe 16, the control box 17, and the one-way connecting pipe 18 (for ease of understanding, the right side of the conversion box 14 is set as the air storage interval) (the right side refers to Figure 1 1), then start the motor 31, the motor 31 works by rotating the shaft 32, the shaft 32 rotates and drives the transmission shaft 2 33 to rotate through the cooperation of the gear set 2 34, at this time, the transmission shaft 2 33 rotates and drives the rotating shaft 37 on the left to rotate, thereby driving the turntable 28 on the left to rotate, the turntable 28 on the left rotates and drives the left movable plate 24 to move through the cooperation of the magnetic block 1 27 and the magnetic block 2 29, so that the protective gas originally stored in the interval is squeezed out from the conversion box 14, and then transported to the body 1 through the circulation pipe 40. At the same time, in the specific use process, the rotation speed can be changed, such as increasing the rotation speed at this time, so that the movable plate 24 is sucked before it is reset, thereby realizing a short-distance reciprocating movement, so that the gas in the body 1 can produce a reciprocating suction and exhaust effect under the cooperation of the circulation pipe 40, thereby generating air flow, on the one hand, so that the protective gas can better contact with the charged lithium battery in the crushing process, on the other hand, it can also play a cooling effect, thereby improving the protection of the star-shaped impeller 13.

[0054] Crushing: Turn on the energy-saving motor 8. The operation of the energy-saving motor 8 can make the two shafts 9 rotate in opposite directions, thereby completing the crushing. Whether to use protective gas or the air itself during the crushing process should be determined based on the overall charge of the lithium battery. When there is no need to use protective gas, the circulation of gas in the body 1 can be achieved with the cooperation of the vacuum pump 15 and the motor 31, thereby achieving a cooling and protective effect.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
