[0001] The present invention relates to the technical field of floor grinding, and specifically to a floor grinding machine adaptable to ground protrusions, which changes the pressure of grinding discs at different heights so as to further grind the ground protrusions. Background Art

[0002] A floor grinding machine is a professional ground treatment device, mainly used for grinding terrazzo, concrete surface layer, epoxy mortar layer, old epoxy floor, etc. It removes impurities such as unevenness, stains, and old coatings on the ground through mechanical impact and friction grinding, making the ground surface flat and smooth, thereby improving the aesthetics and durability of the ground. The background technology of floor grinding machines involves multiple fields, including mechanical engineering, materials science, automation control, etc. With the development of technology, floor grinding machines are also constantly innovating in technology to meet the market demand. Currently, the development trend of floor grinding machines is towards being more efficient, more environmentally friendly, and more intelligent.

[0035] The weight of the counterweight block 305 can be increased or decreased according to actual situations.

[0036] By using the reciprocating lead screw 201, slider 202, transmission rod 203, limit block 204 and through hole three 208, during the grinding process, the grinding disc 210 moves reciprocally, which can grind general corners and greatly reduce the dead corners of general grinders.

[0037] Among them, a motor 212 is fixedly connected inside the counterweight box 301. The output end of the motor 212 penetrates the counterweight box 301, and the output end of the motor 212 is in transmission connection with the reciprocating lead screw 201.

[0038] Among them, a plurality of chutes two 306 are formed on the inner wall surface of the counterweight box 301, and sliding protrusions 307 are fixedly connected to both sides of the support plate 303 in the chutes two 306.

[0039] Among them, the dust suction unit 4 includes a blower housing 401. The surface of the blower housing 401 is fixedly connected to the fixing plate 205. The reciprocating lead screw 201 penetrates the blower housing 401. A through hole one 402 is formed on one side of the blower housing 401. A suction blade 403 is arranged inside the blower housing 401. The top end of the suction blade 403 is fixedly connected to the reciprocating lead screw 201. A through hole two 404 is horizontally formed inside the fixing plate 205. The through hole one 402 and the through hole two 404 are communicated.

[0040] Among them, the moving mechanism 5 includes a control box 501. Tripods 502 and connecting rods 504 are symmetrically and rotatably connected to both sides of the control box 501. The connecting rod 504 is parallel to the bottom of the tripod 502. The other end of the connecting rod 504 is rotatably connected to the dust collector 405. One end of the bottom of the tripod 502 is rotatably connected to the dust collector 405. One ends of the tops of the two tripods 502 are fixedly connected with a push rod 503.

[0041] Among them, a plurality of wheels 505 are rotatably connected to the bottom ends of both sides of the control box 501.

[0042] Among them, a dust-proof strip 211 is fixedly connected to the surface of the fixing plate 205.

[0043] During the grinding process, a large amount of dust will be generated. The dust-proof strip 211 can reduce the diffusion of dust and is more conducive to the dust suction unit 4 to absorb dust.

[0044] Embodiment:

[0045] Such as Figure 1-8As shown, in this embodiment, by pushing the push rod 503, the push rod 503 pushes the grinding mechanism 1 and the moving mechanism 5 to move through the tripod 502, and the motor 212 is started. The motor 212 is connected to the reciprocating screw 201 through a linkage transmission. The motor 212 drives the reciprocating screw 201 to rotate. During the rotation of the motor 212, the slider 202 on its surface reciprocates up and down, the slider 202 drives the transmission rod 203 on the surface to move, and the transmission rod 203 drives the limit block 204 at one end to reciprocate on the surface of the fixed plate 205. The limit block 204 drives the sliding column 209 to move, and the top end of the sliding column 209 moves in the slide groove 1 302, and the bottom end of the sliding column 209 moves in the slide groove 3 207. The top end of the sliding column 209 slides on the bottom surface of the support plate 303, and the sliding column 209 drives the grinding sheet 210 to reciprocate, and the grinding sheet 210 grinds the ground.

[0046] It should be noted that the number of the slider 202 , the transmission rod 203 , the sliding column 209 , and the grinding sheet 210 is preferably three, and three are taken as an example for description herein.

[0047] When the grinding discs 210 are grinding the ground, when one of the grinding discs 210 encounters a protrusion on the ground, the grinding disc 210 at the protrusion will lift up the counterweight 305 through the sliding column 209 and the support plate 303 at its top, and the force on the grinding disc 210 will increase, while the force on the other two will decrease. When two of the grinding discs 210 encounter a protrusion on the bottom surface, the corresponding two support plates 303 will lift up the counterweight 305, and the force of the counterweight 305 on the two lifted support plates 303 will increase, while the force on the two unlifted support plates 303 will decrease. When the three grinding discs 210 are in a plane, the pressure of the counterweight 305 on the three support plates 303 is the same.

[0048] When the motor 212 drives the reciprocating screw 201 to rotate, the reciprocating screw 201 drives the suction blades 403 in the dust collection unit 4 to rotate. While rotating, the suction blades 403 suck the dust on the ground into the fan housing 401. Then, through the negative pressure generated by the rotation of the suction blades 403, the dust enters the dust collector 405 through the through hole 1 402 and the through hole 2 404. The dust collector 405 is an existing mechanism and will not be elaborated here. During operation, most of the dust generated by the grinding disc 210 will be blocked by the dustproof strip 211.

[0049] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
