The filter screen 18 is fixedly connected to one side inside the inner frame 17. The filter screen 18 can intercept metal debris sucked into the dust collection box 13 to achieve air-dust separation. Vibration motors 19 are fixedly installed at both ends on the other side inside the inner frame 17. The vibration motors 19 help shake off the debris attached to the surface of the filter screen 18 by vibration, preventing the filter screen 18 from clogging.
[0035] Reference Figure 4 and Figure 5The inner wall of the mounting frame 16 has sliding grooves 20 on both sides. The inner walls of the two sliding grooves 20 are slidably connected to the sliding strips 21, and the two sliding strips 21 are fixedly connected to the two sides of the inner frame 17 respectively. The sliding grooves 20 provide space for the sliding strips 21 to slide, so that the inner frame 17 can vibrate within a certain range. Several springs 22 are fixedly connected to both sides of the sliding strips 21, and one end of the several springs 22 is fixedly connected to the inner wall of the sliding groove 20. When the vibration motor 19 is working, the springs 22 provide support and reset force to assist the vibration of the inner frame 17.

[0037] Reference Figure 1 A pusher 8 is fixedly connected to the side of the placement plate 5 away from the iron sheet 10. The pusher 8 allows the operator to manually push the placement plate 5 to slide on the guide groove 12, which is convenient for loading and unloading workpieces.
[0038] Reference Figure 1 A tempered glass window 9 is fixedly installed on the front side of the protective cover 2. The tempered glass window 9 not only ensures the sealing of the protective cover 2, but also allows the operator to clearly observe the internal polishing operation.
[0039] Reference Figure 3 The dust suction head 14 is connected to the inside of the dust collection box 13, and the input end of the fan 15 is connected to the inside of the dust collection box 13. This connection structure allows the suction force generated by the fan 15 to be effectively applied, sucking the debris from the dust suction head 14 into the dust collection box 13.
[0040] Reference Figure 1 A guide opening 24 is provided on one side of the top of the protective cover 2. A guide rail 23 is slidably connected to the inner wall of the guide opening 24, and the bottom of the guide rail 23 is fixedly connected to the polishing head 4. The guide opening 24 and the guide rail 23 cooperate to provide guidance for the lifting and lowering movement of the polishing head 4, ensuring the smoothness and accuracy of its movement.
[0041] Working principle: The excavator foot pedal valve to be processed is placed on the placement plate 5. By activating the clamping cylinders 6 on both sides, the two clamping plates 7 are brought closer together, clamping and fixing the foot pedal valve. With the help of the guide groove 12, the placement plate 5 holding the foot pedal valve can be pushed into the protective cover 2. The electromagnet 11 is activated to attract the iron plate 10 on the side of the placement plate 5 for fixation. By activating the lifting cylinder 3, the polishing head 4 is moved down. The polishing head 4 is driven by the motor inside to rotate the polishing wheel at high speed to polish the foot pedal valve. Since the polishing process is completed inside the protective cover 2, the human body is located in front of the device, and the scattered metal debris generated during polishing is contained by the protective cover 2. The system employs a barrier to protect against harm to the user. During the polishing of the excavator's foot pedal valve, the blower 15 is activated, and the dust suction head 14 sucks the metal debris generated during polishing into the dust collection box 13, where it is blocked by a filter screen 18. By periodically activating the vibration motor 19, the vibration amplitude of the filter screen 18 is increased through the cooperation of the slide groove 20, slide bar 21, and spring 22, effectively shaking off the debris attached to the surface of the filter screen 18 to clear any blockages. This system continuously collects the metal debris generated during polishing, making cleaning convenient. After processing is complete, the electromagnet 11 is turned off, allowing the polished foot pedal valve workpiece to be extracted.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
