[0015] The beneficial effects of this utility model are as follows: By setting a reciprocating assembly, when grinding the floor surface, the electric push rod is activated via the control terminal, causing its output end to drive the grinding plate downwards. Once the grinding plate contacts the floor surface, the drive motor is activated via the control terminal, causing the support rod to rotate. The rotation of the support rod, in turn, drives the grinding plate to rotate, allowing the grinding plate to grind the floor surface. Simultaneously, the exhaust fan is turned on via the control terminal, sucking in the dust generated during grinding. The dust is then filtered through a filter inside the housing. Finally, a servo motor is activated via the control terminal, driving the rotating rod... The rotation of the rotating rod drives the eccentric wheel to rotate. When the eccentric wheel rotates upward, it drives the roller to rise, which in turn drives the filter screen to rise. When the eccentric wheel rotates downward, it drives the roller to fall, which in turn drives the filter screen to fall. This creates a reciprocating motion of the filter screen, preventing dust from adhering to it and causing clogging. Simultaneously, the damper and second spring cushion the filter screen during this reciprocating motion, preventing excessive swaying of the second spring and thus improving dust collection efficiency and overall floor grinding efficiency.

[0016] 2. By setting up a fixed plate, a limiting rod, a first spring, a plug-in block, and a limiting slot, when it is necessary to replace the grinding plate after long-term use, the limiting rod is pulled to separate from the limiting slot, making it easy to remove the grinding plate for replacement. When installing the grinding plate, the limiting rod is pulled again to a certain distance, and after the top of the grinding plate is aligned with the bottom of the support rod, the limiting rod is loosened, allowing it to return to its original position under the action of the first spring. This causes the limiting rod to re-engage with the limiting slot, thus completing the installation of the grinding plate. This enables convenient installation and removal of the grinding plate, thereby improving the work efficiency of the staff. Attached Figure Description
