DETAILED DESCRIPTION

[0024] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0025] A crushing mechanism for a crusher, as shown in Figures 1 to 6 , comprising a bin 1, a first crushing disc 2 and two second crushing discs 3.

[0026] The bin 1 comprises a shell 10 and an end cover 11, and the end cover 11 is rotatably connected to the shell 10. Specifically, the end cover 11 is hingedly connected to the shell 10.

[0027] The first crushing disc 2 is rotatably arranged in the bin 1. Specifically, the first crushing disc 2 is located in the shell 10, and the first crushing disc 2 is driven to rotate by a rotary drive source. The rotary drive source is preferably a motor, and the output end of the motor drives the first crushing disc 2 to rotate through a driving belt and a driving wheel.

[0028] The two second crushing discs 3 are fixedly installed in the bin 1, and the two second crushing discs 3 are oppositely arranged. Specifically, the two second crushing discs 3 are fixedly installed in the shell 10 and the end cover 11, respectively.

[0029] The first crushing disc 2 is located between the two second crushing discs 3, and the first crushing disc 2 is coaxially arranged with the two second crushing discs 3. This arrangement can make the overall structure more compact, effectively reduce the space occupation, and the rotation of the first crushing disc 2 can simultaneously cooperate with the two second crushing discs 3 to crush the material, thereby effectively improving the crushing efficiency.

[0030] The first pulverizing disc 2 is provided with a plurality of first pulverizing teeth 4 distributed at intervals, and the first pulverizing teeth 4 are uniformly distributed in the circumferential direction. The two second pulverizing discs 3 are each provided with a plurality of pulverizing portions 7 distributed at intervals. The uniformly distributed first pulverizing teeth 4 and the pulverizing portions 7 can ensure that the material is subjected to the same pulverizing force at each position during pulverization, thereby improving the pulverization efficiency and the pulverization effect.

[0031] The first pulverizing disc 2 is provided with at least two second pulverizing teeth 5 and at least two third pulverizing teeth 6 arranged at intervals. The two second pulverizing teeth 5 are oppositely arranged, and the two third pulverizing teeth 6 are oppositely arranged. The second pulverizing teeth 5 and the third pulverizing teeth 6 enable the material to be subjected to pulverizing force in different directions at different positions during pulverization, thereby enabling the material to be more effectively pulverized and improving the pulverization effect.

[0032] The plurality of first pulverizing teeth 4 are located outside the plurality of pulverizing portions 7 in the radial direction, and the plurality of first pulverizing teeth 4 and the plurality of pulverizing portions 7 are distributed at intervals. The two second pulverizing teeth 5 and the two third pulverizing teeth 6 are located inside the plurality of pulverizing portions 7 in the radial direction, and the two second pulverizing teeth 5 and the two third pulverizing teeth 6 and the plurality of pulverizing portions 7 are distributed at intervals. Through the cooperation of the first pulverizing teeth 4, the pulverizing portions 7, and the second pulverizing teeth 5 and the third pulverizing teeth 6, multi-level pulverization of the material is achieved, which not only effectively improves the pulverization efficiency but also improves the pulverization effect.

[0033] Arc-shaped grooves 8 are arranged on the surfaces of the plurality of first pulverizing teeth 4, the two second pulverizing teeth 5, and the two third pulverizing teeth 6. The arc-shaped grooves 8 can effectively increase the contact area with the material, so that more material can be simultaneously pulverized, thereby improving the pulverization efficiency. In addition, the arc-shaped grooves 8 can guide the orderly flow of the material during the pulverization process, avoiding the accumulation or blockage of the material, and further improving the pulverization effect.

[0034] The plurality of pulverizing portions 7 each comprise two closely arranged protrusions 9. The cross section of the two protrusions 9 is hexagonal. The hexagonal cross section can effectively increase the contact area between the material and the pulverizing portion 7, thereby improving the pulverization efficiency. In addition, the hexagonal cross section enables the pulverizing portion 7 to pulverize the material from multiple directions, which is helpful to produce a more uniform and delicate pulverization effect.

[0035] A ring-shaped filter screen 12 is arranged in the hopper 1. The filter screen 12 divides the hopper 1 into a pulverizing cavity 13 and a screening cavity 14. The hopper 1 is provided with an inlet channel 15 and an outlet channel 16. The inlet channel 15 is in communication with the pulverizing cavity 13, and the outlet channel 16 is in communication with the screening cavity 14. The first pulverizing disc 2 and the two second pulverizing discs 3 are located in the pulverizing cavity 13.

[0036] It should be noted that the material enters the crushing cavity 13 from the feeding channel 15, and after being crushed in the crushing cavity 13, the qualified material enters the screening cavity 14 through the filter screen 12, and then enters the discharging channel 16, and the material that cannot pass through the filter screen 12 is left in the crushing cavity 13 to continue crushing, so that the crushing effect on the material is improved.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present application; those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
