[0020] Example 1:

[0021] Reference Figure 1-3 A dust removal device for a mining crusher includes a main frame 1 and a crushing output chamber 6. The main frame 1 is fixed parallel to the right side of the crushing output chamber 6 and connected by bolts. A main motor 2 and a control board 3 are installed on the top of the main frame 1. The control board 3 is connected to the main motor 2 via a cable and is used to control the start, stop, and speed adjustment of the main motor. The output end of the main motor 2 is connected to a transmission group 4 via a coupling. The transmission group 4 consists of a pulley and a transmission shaft, and its other end is rigidly connected to an upper connecting cover plate 5. The upper connecting cover plate 5 is fixed to the upper opening of the crushing output chamber 6 via a flange, forming a sealed structure. The crushing output chamber 6 contains crushing components, and the transmission group 4 is linked to the internal crushing components via a transmission shaft passing through the upper connecting cover plate 5. Dust removal components 8 are symmetrically installed on both sides of the crushing output chamber 6 to simultaneously adsorb dust during the crushing process.

[0022] The crushing components specifically include a hydraulic output cylinder 101, a crushing output shaft 102, a protective bushing 103, a gear set 104, a side output component 105, and a crusher head 106. The hydraulic output cylinder 101 receives power from the main motor 2 via the transmission shaft of the transmission group 4, and its piston rod is connected to the top of the crushing output shaft 102. A wear-resistant metal protective bushing 103 is fitted onto the surface of the crushing output shaft 102, and a conical crusher head 106 is welded to its bottom end for impact crushing of the ore. Gear sets 104 are provided on both sides of the crushing output shaft 102, meshing with the input end of the side output component 105. The side output component 105 is connected to the dust removal component 8 via a transmission rod, achieving synchronous transmission of crushing power to the dust removal component.

[0023] The dust removal component 8 includes a dust removal motor 201, a micro compressor 202, an airflow circulation chamber 203, and independent suction pipes 204. The dust removal motor 201 is fixed to the outer wall of the crushing output chamber 6 by a bracket, and its output shaft is connected to the micro compressor 202 by a coupling. The airflow circulation chamber 203 is connected to the bottom of the micro compressor 202. A removable metal filter screen is installed inside the airflow circulation chamber 203 to filter the sucked-in dust. Six independent suction pipes 204 are distributed parallel to each other at the bottom of the airflow circulation chamber 203. Each pipe has 20 suction holes with an inner diameter of 3 mm, which are evenly distributed on the surface of the pipe to cover the dust diffusion area in the crushing chamber.

[0024] Furthermore, a positioning support plate 7 is welded to the bottom of the crushing output chamber 6. This support plate is an L-shaped steel plate that is fixed to the ground by bolts to stabilize the position of the crushing output chamber 6 and reduce vibration displacement.

[0025] Example 2:

[0026] Reference Figure 1-3 Similar to Example 1, but with a further optimization of the layout of the independent suction pipes 204. The six pipes are divided into upper and lower layers, with three pipes in each layer arranged in a staggered pattern to expand the suction coverage. Simultaneously, the filter of the airflow circulation chamber 203 is replaced with a multi-layer composite filter material to improve the filtration effect on fine dust. The remaining structure and workflow are the same as in Example 1.

[0027] Example 3:

[0028] Reference Figure 1-3 Similar to Embodiment 1, but with a further improvement, a rubber shock-absorbing pad is added at the connection between the positioning support plate 7 and the crushing output chamber 6 to further reduce the vibration and noise generated during crushing. The micro compressor 202 of the dust removal component 8 is replaced with a variable frequency compressor, and its power is adjusted by the control board 3 to achieve adaptive control of dust concentration. The rest of the structure is the same as in Embodiment 1.

[0029] The working principle of this device is as follows:

[0030] After the operator activates control panel 3, main motor 2 drives transmission group 4 to rotate crushing output shaft 102 at high speed, and crusher head 106 crushes the ore. Simultaneously, dust removal motor 201 starts micro compressor 202, creating negative pressure in airflow circulation chamber 203, and drawing in dust-laden air through the suction holes on independent suction branch pipe 204. After dust is intercepted by filter screen, clean air is discharged from exhaust port. The filter screen can be cleaned or replaced regularly through the maintenance door on the side of the chamber. Side output component 105 transmits part of the crushing power to dust removal component 8, ensuring the synchronization of dust removal operation and crushing action, and improving dust removal efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
