When it is necessary to install a new grinding disc 34, the new grinding disc 34 can be positioned and connected to the positioning insert 33 through the slot 35, and then the screw 37 can be threaded to the lower end of the grinding head machine 24 through the positioning plate seat 36 to complete the quick installation.
[0031] Example 2:
[0032] Please see Figures 1-5Compared to Embodiment 1, this embodiment of the present invention provides a manual polishing machine with a quick-release grinding disc mounting structure, which further includes: a sewage discharge assembly 4, a placement seat 41 placed at the lower end of the grinding disc 34, a slag guide hopper 42 fixedly connected to the upper side of the placement seat 41, a collection box 43 fixedly connected to the lower rear side of the slag guide hopper 42, a sliding rod 44 fixedly connected to the inside of the collection box 43, a sliding groove airbag 45 placed at both ends of the sliding groove and slidably connected to the sliding rod 44, a filter suction head 46 fixedly connected to the middle of the sliding groove airbag 45, a filter screen provided inside the filter suction head 46, a suction pipe 47 whose front end passes through the collection box 43 and is fixedly connected to the filter suction head 46, and a suction pump 48 whose upper end is fixedly connected to the rear end of the suction pipe 47. After the suction pump 48 is started, it can extract water from the collection box 43 at the filter suction head 46 through the suction pipe 47. The suction pump 48 is fixedly connected to the rear end of the collection box 43.
[0033] In this embodiment:
[0034] When it is necessary to collect and remove the wastewater and dust generated during polishing, the wastewater and dust generated during the polishing of the stone can be blocked by the anti-splash cover 32 and fall onto the placement seat 41 and guided into the slag hopper 42. When the wastewater and dust fall into the slag hopper 42, they can be guided and transported to the collection box 43 for collection. When the wastewater enters the collection box 43, the buoyancy can drive the sliding airbag 45 and its upper part to move upward, preventing the filter suction head 46 from being placed inside the mud and water. Then, the controller 25 controls the suction pump 48 to start. After the suction pump 48 starts, the water in the collection box 43 at the filter suction head 46 can be extracted and discharged through the suction pipe 47. When the wastewater passes through the filter suction head 46, it can be filtered to prevent impurities from entering the suction pipe 47 and causing damage to the suction pump 48.
