A first crushing assembly is provided inside the box body 1, and the first crushing assembly includes a crushing knife 6 fixedly connected to the outside of the first rotating shaft 5. The number of the crushing knives 6 is multiple and distributed correspondingly. The raw materials can be stored and crushed by providing the first crushing assembly.

[0021] Specifically, a filter plate 14 is fixedly connected to the inside of the box body 1, and a pushing assembly is provided on the top of the filter plate 14. The pushing assembly includes a telescopic cylinder 17 provided on one side of the box body 1, and the output end of the telescopic cylinder 17 is fixedly connected to a push plate 18. Through the provided pushing assembly, the raw materials on the filter plate 14 can be pushed to the inside of the collection shell 16. A second motor 12 is provided on one side of the box body 1, and a transmission assembly is provided on one side of the second motor 12. The transmission assembly includes a first gear 10 fixedly sleeved on the outside of one of the second rotating shafts 8, and a second gear 11 fixedly sleeved on the outside of the other second rotating shaft 8. The first gear 10 and the second gear 11 are meshed and connected. Through the provided transmission assembly, the two second rotating shafts 8 can rotate simultaneously.

[0022] Specifically, a second crushing assembly is provided inside the box body 1. The second crushing assembly includes two correspondingly distributed second rotating shafts 8 that are rotatably connected to both sides of the inner wall of the box body 1, wherein the two second rotating shafts 8 extend to the outside of the box body 1, and each two second rotating shafts 8 form a group. The same crushing roller 9 is fixedly connected between each group of second rotating shafts 8, and the output end of the second motor 12 is fixedly connected to one end of one of the second rotating shafts 8. The raw material can be crushed for the second time through the provided second crushing assembly.

[0023] Specifically, a discharge chute 15 is opened on one side of the box body 1, a collecting shell 16 is fixedly connected to one side of the box body 1, and discharge plates 7 are fixedly connected on both sides of the inner wall of the box body 1.

A support plate 13 is fixedly connected to one side of the box body 1, and the second motor 12 is fixedly installed on the support plate 13. By setting the support plate 13, the second motor 12 will not idle during operation.

[0024] During use: During the production and processing of graphite electrode materials for lithium batteries, when the graphite electrode materials need to be crushed, first pour the raw materials from the feed shell 2 into the interior of the box body 1, and then start the first motor 4. At this time, the output end of the first motor 4 drives the first shaft 5 to start rotating. Through the rotation of the first shaft 5, the crushing knife 6 can be driven to start rotating. At this time, the raw materials can be preliminarily crushed. The raw materials after preliminary crushing will pass through the blanking plate 7 and enter the interior of the two crushing rollers 9. At this time, start the second motor 12. At this time, the output end of the second motor 12 drives one of the second shafts 8 to start rotating. Through the rotation of one of the second shafts 8, the first gear 10 can be driven to start rotating. Since the first gear 10 is engaged with the second gear 11, the second gear 11 can be driven to start rotating through the rotation of the first gear 10. At this time, the two second shafts 8 rotates simultaneously, and the rotation of the two second rotating shafts 8 can drive the two crushing rollers 9 to start rotating in opposite directions. The opposite rotation of the two crushing rollers 9 can perform secondary crushing on the raw materials. The crushed raw materials will fall onto the filter plate 14, and the qualified raw materials will pass through the filter plate 14 into the bottom of the box body 1. By starting the telescopic cylinder 17, the output end of the telescopic cylinder 17 drives the push plate 18 to start moving. The raw materials on the filter plate 14 can be pushed into the interior of the collecting shell 16 through the movement of the push plate 18. The raw materials can be crushed by setting the above components. After the secondary crushing of the raw materials, the crushing effect is improved and the crushing speed is accelerated. The crushed raw materials can also be detected and classified. The raw materials that are not completely crushed will be crushed again. The above structure is greatly convenient for the staff to use and reduces the unnecessary workload of the staff.
