DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 , this embodiment provides the following technical solutions:

[0022] like Figure 1-Figure 3As shown, a floor finishing machine comprises: a finishing frame 1, a baffle plate 2 is fixedly installed at one end of the finishing frame 1, a reduction motor 3 is fixedly installed on the upper surface of the baffle plate 2, the output shaft of the reduction motor 3 passes through the baffle plate 2, and a floor finishing and grinding component 4 is fixedly installed at the end, a dust suction component 5 is fixedly installed on the inner wall of the baffle plate 2, and the dust suction component 5 is surrounded by the periphery of the floor finishing and grinding component 4.

[0023] The floor finishing and polishing assembly 4 includes a vacuum cleaner 501, which is fixedly installed in the finishing frame 1. The vacuum pipe 502 of the vacuum cleaner 501 passes through both sides of the finishing frame 1 and is inserted into the enclosure plate 2. A dust suction ring 503 is fixedly installed on the inner wall of the enclosure plate 2, and the dust suction ring 503 is connected to the dust suction pipe 502.

[0024] The dust suction ring 503 is sleeved around the periphery of the floor finishing and polishing assembly 4 .

[0025] Through the design of the floor finishing and grinding component 4, the reduction motor 3 and the dust suction component 5, when the floor is being polished and trimmed, the trimming frame 1 can be pushed to the corresponding floor mat, and then the enclosure plate 2 will cover the part to be polished, and at the same time, the floor finishing and grinding component 4 in the enclosure plate 2 will touch the protruding part of the floor, and the protruding part of the floor will press the floor finishing and grinding component 4 to float upward, so that the trimming frame 1 can be prevented from being lifted up due to the protruding part, and at the same time, the enclosure plate 2 can be ensured to fit the floor. The tightness of the surface can avoid the occurrence of dust splashing during grinding, and then the reduction motor 3 can be started to drive the ground finishing and grinding component 4 to grind the raised parts, and with the progress of grinding, the ground finishing and grinding component 4 will descend together, so that it always touches the surface of the raised parts, and during the grinding process, the vacuum cleaner 501 can sweep the dust generated by grinding in the baffle plate 2 through the dust suction ring 503, so as to reduce the dust generated during the grinding process, which is harmful to the health of the staff and blocks the field of vision.

[0026] like Figure 4 As shown, the floor finishing and grinding assembly 4 includes a rotating disk 401, which is fixedly mounted on the lower surface of the output shaft of the reduction motor 3. The rotating disk 401 rotates in the enclosure disk 2 and is surrounded by the dust collection ring 503. An installation groove 407 is opened on the lower surface of the rotating disk 401, and a grinding disk 405 is slidably mounted in the installation groove 407.

[0027] A guide rail groove 402 is provided in the installation groove 407 , a limiting column 403 is fixedly installed in the guide rail groove 402 , a guide rail block 406 is slidably installed in the guide rail groove 402 and on the outer surface of the limiting column 403 , and the guide rail block 406 is fixedly installed on the outer surface of the grinding disc 405 .

[0028] Two groups of floating springs 404 are mounted on the outer surface of the limiting column 403 . The two groups of floating springs 404 are respectively fixedly connected to the upper and lower surfaces of the guide rail block 406 . The other ends of the two groups of floating springs 404 are respectively fixedly connected to the upper and lower surfaces of the guide rail slot 402 .

[0029] By designing the rotating disk 401, the guide groove 402, the floating spring 404 and the grinding disk 405, when the enclosure disk 2 covers the required grinding ground part, the grinding disk 405 in the enclosure disk 2 will touch the raised part of the ground, and the grinding disk 405 will retreat through the guide groove 402 of the guide block 406 and the installation groove 407 of the grinding disk 405, so that the grinding disk 405 can move up to the highest point of the raised part of the ground, and the guide block 406 will slide upward in the guide groove 402. The floating spring 404 is pressed on one end of the upper end and pulls the floating spring 404 at the lower end at the same time, so that the grinding disc 405 can float upward at the same height according to the height of the raised ground, so as to avoid the trimming frame 1 being lifted up due to the raised ground part, and at the same time, it can ensure the tightness of the surrounding plate 2 to the ground. The grinding disc 405 will touch the raised ground through the top pressure and pulling force of the floating spring 404, so that the reduction motor 3 can drive the grinding operation on the raised ground.

[0030] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when grinding and trimming the ground, the trimming frame 1 can be pushed to the corresponding ground mat, and then the enclosure plate 2 will cover the part to be polished, and at the same time, the grinding disc 405 in the enclosure plate 2 will touch the raised part of the ground, and the grinding disc 405 will retreat through the guide groove 402 of the guide block 406 and the installation groove 407 of the grinding disc 405, so that the grinding disc 405 can move up to the highest point of the raised part of the ground, and the guide block 406 moves upward in the guide groove 402. During the sliding process, one end of the floating spring 404 at the upper end will be pressed, and the floating spring 404 at the lower end will be pulled at the same time, so that the grinding disc 405 can float upward at the same height according to the height of the ground protrusion, and then the reduction motor 3 can be started to drive the grinding disc 405 to grind the raised ground part, and as the grinding progresses, the grinding disc 405 will descend together and always touch the raised part until it is polished flat, and during the grinding process, the vacuum cleaner 501 can sweep the dust generated by grinding in the enclosure disc 2 through the dust suction ring 503.

[0031] In summary: by making the grinding disc rise to the same height as the raised part, it is possible to avoid the top of the trimmed frame being lifted up due to the raised part, so that it has stability during the grinding of the raised part, and at the same time it can also maintain the airtightness of the enclosure disc against the ground, which can minimize the splashing of dust.
