Crushers can crush and break various waste materials, such as construction waste, waste metals, etc., which helps to convert waste materials into recyclable resources, reduce environmental pollution, and achieve the recycling of resources; in some industries, raw materials often need to be crushed to reach the required particle size. By using crushers, the particle size and distribution of materials can be better controlled, and the utilization rate of raw materials and product quality can be improved.

[0023] Among them, the traditional inclined surface teeth 12 can be stuck into or cut into items during the rolling movement. Ideally, the broken objects will automatically fall off when the two teeth are separated. However, when encountering soft items, if the angle is inappropriate, they will rotate with the toothed wheel 10, resulting in the phenomenon of sticking teeth. In the force analysis shown in the design diagram of the present application, when the angle is 50°, it is the best state; the items to be broken are placed and input into the inside of the unpacking box 2, and the items will fall between the two toothed wheels 10. The toothed wheels 10 rotate in opposite directions to break the items, and the broken items will fall into the collection box 3 for subsequent processing.

[0025] Among them, the toothed wheels 10 are rotationally connected to the inner wall of the unpacking box 2 through the connecting shafts 11 at both ends. The driving gear 8 is meshed and connected so that the two toothed wheels 10 can rotate in opposite directions, and the distance between the two toothed wheels 10 will not damage the inclined teeth 12 during rotation.

[0026] The driving gear 8 is arranged outside the unpacking box 2, and the two driving gears 8 are meshed and connected; a protective frame 7 is fixedly installed on one side of the unpacking box 2, and the driving gear 8 is arranged inside the protective frame 7; a driving motor 4 is fixedly installed outside the protective frame 7, and the output end of the driving motor 4 penetrates the inner wall of the protective frame 7 and is fixedly connected to one side of the driving gear 8.

The items will fall between the two toothed wheels 10. The driving motor 4 is installed on the outer side of the protective frame 7 by bolts, and its output end penetrates the protective frame 7. The driving motor 4 drives the driving gear 8 to rotate, causing the two driving gears 8 to rotate in opposite directions, thereby driving the toothed wheels 10 to rotate in opposite directions, and the items can be broken. The traditional inclined surface teeth 12 can catch or cut into the items during the rolling movement. Ideally, the broken items will automatically fall off when the two teeth are separated. However, when encountering soft items, if the angle is inappropriate, they will rotate with the toothed wheel 10, resulting in the phenomenon of sticking teeth. In the force analysis shown in this design diagram, the best state is when the angle is 50°. The items broken by the toothed wheels 10 inside the bag-breaking box 2 will fall into the interior of the collection box 3 uniformly through the centralized trough 9. The interior of the centralized trough 9 is funnel-shaped, which can make the broken items fully fall into the collection box 3. Moreover, the inner wall of the centralized trough 9 is relatively smooth, and the items will not be left in the interior of the centralized trough 9, facilitating subsequent processing.
