The crusher body 2 and the first driving mechanism 3 are both arranged on the bracket 1. A hopper 7 is provided at the upper end of the crusher body 2. The first driving mechanism 3 drives the second driving mechanism 4 to rotate, and the second driving mechanism 4 drives the cover 5 to rise or fall. The cover 5 is located above the hopper 7. A receiving groove 8 is provided at the upper end of the hopper 7. A sealing ring 9 is provided in the receiving groove 8. A feed pipe 10 is provided on the side of the hopper 7. The feed pipe 10 is used to transport the material to be crushed into the hopper 7. The dust extraction mechanism 6 is provided on the hopper 7. The dust extraction mechanism 6 is used to extract the dust generated when the crusher body 2 is operating.

[0027] When it is necessary to maintain the interior of the crusher body 2, the second drive mechanism 4 drives the cover body 5 to move upward, so that the cover body 5 is away from the hopper 7, and the first drive mechanism 3 drives the second drive mechanism 4 to rotate, so as not to affect the maintenance work inside the crusher body 2. After the maintenance of the crusher body 2 is completed, the first drive mechanism 3 drives the second drive mechanism 4 to rotate, and stops when the cover body 5 is above the hopper 7. Then the second drive mechanism 4 drives the cover body 5 to descend, so that the cover body 5 is close to the hopper 7. The sealing ring 9 seals the cover body 5 and the hopper 7. The dust extraction mechanism 6 extracts the dust generated during the operation of the crusher body 2 to prevent the dust from escaping.

[0028] In this embodiment, the first driving mechanism 3 includes a mounting plate 11, a first motor 12, a driving gear 13, a driven gear 14, a rotating rod 15 and a swing arm 16. The mounting plate 11 is fixedly mounted on the outside of the crusher body 2, and the first motor 12 is arranged on the mounting plate 11. The first motor 12 is a servo motor. The first motor 12 drives the driving gear 13, the driving gear 13 engages the driven gear 14, and the driven gear 14 is fixedly mounted on the rotating rod 15. The lower end of the rotating rod 15 passes through the mounting plate 11, and the swing arm 16 is arranged at the upper end of the rotating rod 15. The second driving mechanism 4 is arranged on the swing arm 16. When in use, the first motor 12 drives the driving gear 13 to rotate, and the driving gear 13 drives the driven gear 14 to rotate, so that the rotating rod 15 drives the swing arm 16 to swing, thereby adjusting the relative position of the second driving mechanism 4 and the cover body 5.

[0029] In this embodiment, the first driving mechanism 3 further includes a bearing 17 . The bearing 17 is disposed on the bracket 1 , and the lower end of the rotating rod 15 is connected to the bearing 17 . By providing the bearing 17 , the stability of the rotating rod 15 can be improved.

[0030] In this embodiment, the second driving mechanism 4 includes a first cylinder 18 and a telescopic rod 19. The first cylinder 18 is installed on the swing arm 16. The first cylinder 18 drives the cover body 5 to rise or fall. One end of the telescopic rod 19 is connected to the cover body 5, and the other end of the telescopic rod 19 is connected to the cover body 5. When in use, under the driving action of the first cylinder 18, the cover body 5 is moved closer to or away from the hopper 7.

[0031] In this embodiment, the dust extraction mechanism 6 includes a dust box 20, a dust extraction pipe 21, a filter 22 and an exhaust fan 23. The dust box 20 is arranged outside the hopper 7, one end of the dust extraction pipe 21 is connected to the dust box 20, and the other end of the dust extraction pipe 21 is connected to the hopper 7. The filter 22 is arranged inside the dust box 20. The exhaust fan 23 is connected to the dust box 20 through a pipeline. The filter 22 filters the dust and the clean gas is discharged into the atmosphere.

[0032] The working principle of a dust removal device for a crusher in the embodiment of the present application is as follows:

[0033] When it is necessary to maintain the interior of the crusher body 2, the second drive mechanism 4 drives the cover body 5 to move upward, so that the cover body 5 is away from the hopper 7, and the first drive mechanism 3 drives the second drive mechanism 4 to rotate, so as not to affect the maintenance work inside the crusher body 2. After the maintenance of the crusher body 2 is completed, the first drive mechanism 3 drives the second drive mechanism 4 to rotate, and stops when the cover body 5 is above the hopper 7. Then the second drive mechanism 4 drives the cover body 5 to descend, so that the cover body 5 is close to the hopper 7. The sealing ring 9 seals the cover body 5 and the hopper 7. The dust extraction mechanism 6 extracts the dust generated during the operation of the crusher body 2 to prevent the dust from escaping.

[0034] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
