The protective front shell 5 is made of transparent, high-strength plastic. Both the protective rear shell 4 and the protective front shell 5 are made of metal. A grinding table 6 is installed at the front of the protective front shell 5. A collection frame 7 is slidably placed on the upper part of the mounting box 1. The collection frame 7 is located below the collection channel 51. A motor 8 is installed inside the protective cover 3. The output shaft of the motor 8 is connected to a connecting shaft 9. The other end of the connecting shaft 9 passes into the protective rear shell 4 and is connected to a grinding disc 10 by welding. The connecting shaft 9 is rotatably connected to the protective rear shell 4. A rotating frame 901 is rotatably connected to the connecting shaft 9. The rotating frame 901 is fixedly connected to the protective rear shell 4. Multiple fan blades 13 are evenly rotated around the front of the rotating frame 901. A driven gear 12 is connected to the rear end of each fan blade 13 by welding. A driving gear 11 is connected to the connecting shaft 9 by welding. The rotating frame 901 is located in front of the driving gear 11. The driving gear 11 meshes with the driven gear 12. The control panel 31 is electrically connected to the motor 8.

[0026] like Figure 5 and Figure 6As shown, it also includes a filter screen 41 and a scraper 14. The filter screen 41 is provided inside the protective rear shell 4, and the scraper 14 is installed on the connecting shaft 9 by screws. The scraper 14 is located in front of the filter screen 41.

[0027] like Figure 7 and Figure 8 As shown, it also includes a knob 15, a lead screw 16, an electric clamp 17, a slider 1701, and a guide rod 18.

Large particles of impurities are intercepted by the filter 41, and the purified air is discharged through the ventilation holes on the protective cover 3 and the protective back shell 4 to achieve heat dissipation and airflow circulation. At the same time, the connecting shaft 9 drives the active gear 11 to rotate, driving multiple driven gears 12 to rotate synchronously, thereby driving the fan blade 13 to rotate at high speed, forming a negative pressure airflow to enhance the dust collection effect. The scraper 14 rotates synchronously with the connecting shaft 9 to periodically remove the dust attached to the surface of the filter 41 to prevent clogging and maintain dust collection efficiency. After the polishing task is completed, the power of the motor 8 is turned off, the electric clamp 17 is released, the polished workpiece is removed, and the collection frame 7 located below the collection channel 51 is taken out to clean the accumulated dust and debris. If continued use is required, the above operation steps can be repeated.
