The second motor 53 is mounted on a side wall of the second mounting base 52 near the support tube 51. The output end of the second motor 53 passes through the second mounting base 52 and is rotationally connected to the second mounting base 52. The third spur gear 54 is fixedly mounted on the output end of the second motor 53.

[0044] Reference Figure 2 as well as Figure 4 A second drive assembly is disposed within the housing 11 and includes a screw rod 43 and a second spur gear 44. The screw rod 43 is disposed horizontally at the top of the housing 11. The end of the screw rod 43 near the support tube 51 penetrates into the second mounting seat 52, and the screw rod 43 is rotatably connected to the second mounting seat 52. Two screw rods 43 are provided, and the two screw rods 43 are symmetrically disposed along the axis of the second mounting seat 52.

[0045] Reference Figure 2 as well as Figure 4The second spur gear 44 is fixedly mounted on the end of the screw rod 43 near the second mounting seat 52, and the second spur gear 44 corresponds to the screw rod 43 one by one. The two second spur gears 44 are located above the third spur gear 54, and the two second spur gears 44 are symmetrically arranged along the axis of the third spur gear 54. The two second spur gears 44 are meshed with the third spur gear 54.

[0046] Reference Figure 2 as well as Figure 4 A cleaning assembly 4 is disposed within the housing 11 and includes a first mounting seat 41 and a cleaning brush 42. The first mounting seat 41 is mounted on two screw rods 43, which pass through the first mounting seat 41 and are threadedly engaged with the first mounting seat 41. A plurality of cleaning brushes 42 are disposed on the outer wall of the first mounting seat 41 and are evenly spaced around the circumference of the first mounting seat 41.

[0047] Reference Figure 2 as well as Figure 4 The clamping plate 13, away from the support tube 51, defines a third receiving groove 411 along the circumference of the first mounting seat 41. The cleaning brushes 42 slidably engage the inner sidewalls of the third receiving groove 411, with the plurality of cleaning brushes 42 positioned between the two clamping plates 13. The third receiving groove 411 ensures that the first mounting seat 41 and the cleaning brushes 42 are not affected by the clamping plate 13 during rotation of the housing 11.

[0048] The implementation principle of a ball mill in an embodiment of the present application is: the operator starts the first motor 33, the first motor 33 drives the first spur gear 32 to rotate, the rotation of the first spur gear 32 causes the ring gear 31 to rotate, the rotation of the ring gear 31 causes the machine body 11 to rotate, and the steel balls in the machine body 11 thereby crush the material in the machine body 11.

[0049] When the operator needs to replace the broken lining plate 12, the operator will remove the screws 21 on both sides of the damaged lining plate 12 from the machine body 11. The clamping plate 13 loses the support of the screw 21 and can be moved away from the first accommodating groove 121. After removing the clamping plates 13 on both sides of the damaged lining plate 12, the operator can remove the damaged lining plate 12, thereby facilitating the replacement of the lining plate 12.

[0050] When the operator needs to clean the inner lining plate 12, the operator starts the second motor 53, and the second motor 53 drives the third spur gear 54 to rotate. The rotation of the third spur gear 54 causes the two second spur gears 44 to rotate simultaneously. The simultaneous rotation of the second spur gears 44 of the chain causes the two screw rods 43 to rotate. The rotation of the screw rod 43 causes the first mounting seat 41 to move along the direction of the screw rod 43. The cleaning brush 42 on the first mounting seat 41 cleans the residual material on the inner lining plate 12. By providing the clamping plate 13 and the screw rod 21, the operator can remove the clamping plate 13 through the fixing assembly 2, thereby quickly replacing the inner lining plate 12. Another function of the clamping plate 13 is to further increase the height of the steel ball, increase the impact force of the steel ball on the material, and improve the crushing efficiency.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
