[0001] This utility model relates to the field of floor processing equipment technology, and more specifically, it relates to a floor grinding device. Background Technology

[0002] Floors, also known as floors, are an important part of a house. When constructing floors, grinding equipment is usually used to grind them to make them smoother.

[0003] Publication No. CN214992894U discloses a rapid ground grinding device, the technical solution of which includes a main body, the main body having a first cavity inside, a support plate inside the first cavity, a first rotating shaft and a second rotating shaft respectively on the bottom two sides of the support plate, a brush at the bottom of the first rotating shaft, a support body at the bottom of the second rotating shaft, a grinding disc at the bottom of the support body, a motor at the top of the support plate, a water spray body and a support chamber on the bottom two sides of the main body, and a fan on one side inside the support chamber.

[0004] The above technical solution uses a motor to drive the second rotating shaft to rotate. Simultaneously, the second rotating shaft drives the connecting body to rotate, allowing the grinding disc to grind the ground. A water spray also sprays water from the tank onto the grinding disc, cooling it and further accelerating the grinding efficiency. A fan sends the grinding dust into a dust collection box, improving dust prevention. When the grinding disc needs to be replaced, the device body is tilted to separate the grinding disc from the ground. The grinding disc is then removed and replaced. After replacement, the device body is lifted and the tilted position is lifted, allowing the grinding disc to come into contact with the ground, thus completing the grinding disc replacement.

[0005] However, after the grinding disc is replaced, when the device needs to be lifted again, the device itself is quite heavy, so the staff needs to use a lot of effort to lift it, making the replacement process quite laborious.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a floor grinding device that solves the problem that when the grinding disc is replaced, the staff needs to exert a lot of effort to lift the device again, making the replacement process laborious.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a floor grinding device, comprising a device body and a grinding disc, a fixed plate fixedly connected to the device body, a groove provided on the fixed plate, a movable plate slidably connected in the groove, a first driving component for driving the movable plate to move along the groove on the fixed plate, a rotating plate rotatably connected to the side of the movable plate away from the fixed plate, a motor fixedly connected to the bottom of the rotating plate, the output end of the motor being detachably connected to the grinding disc, and a second driving component for driving the rotating plate to rotate on the movable plate.

[0009] By adopting the above technical solution, when grinding the floor, motor one is started, and the output end of motor one drives the grinding disc to rotate, which grinds the floor. When changing the grinding disc, the first drive component drives the moving plate to move upward along the slide groove, and drives the rotating plate and the grinding disc to move in the same direction. At the same time, the grinding disc and the floor separate. Then, the second drive component drives the rotating plate to rotate in the direction of the moving plate, and drives the grinding disc to rotate. At this time, the grinding disc faces away from the fixed plate. Then, the worker separates the grinding disc from the output end of motor one and replaces the grinding disc. After replacement, the first drive component and the second drive component drive the grinding disc back to its original position, thus completing the grinding disc replacement. The setting of the first drive component and the second drive component can separate the grinding disc from the ground and change the direction of the grinding disc. Therefore, when replacing the grinding disc, the device body does not need to be overturned, which reduces the effort required by the worker to replace the grinding disc and makes it easier for the worker to replace the grinding disc.

[0010] The present invention is further configured such that: the first driving component includes a slider fixedly connected to the side wall of the moving plate, the slider and the slide groove are slidably connected, a screw is rotatably connected in the slide groove, the screw and the slider are threadedly connected, and a second motor is fixedly connected to the fixed plate, the output end of the second motor passing through the fixed plate and fixedly connected to the screw.

[0011] By adopting the above technical solution, when driving the moving plate to move along the slide, the second motor is started, and the output end of the second motor drives the screw to rotate. At the same time, the screw drives the moving plate to move along the slide, and the moving plate drives the moving plate to move in the same direction, thereby achieving the effect of driving the moving plate to move.

[0012] The present invention is further configured such that: the second driving component includes an electric push rod fixedly connected to the moving plate, the output end of the electric push rod is fixedly connected to a connecting block, the side wall of the rotating plate is provided with a connecting groove for the connecting block to slide, and the moving plate and the rotating plate are connected by a hinge.

[0013] By adopting the above technical solution, when the rotating plate is driven to rotate towards the moving plate, the output end of the electric push rod is driven to retract, and at the same time, the connecting block moves towards the moving plate and along one side wall of the connecting groove, and a pulling force is applied to the rotating plate in the direction of the moving plate. At this time, the rotating plate is driven to rotate towards the moving plate due to the pulling force. When the rotating plate is driven back to its original position, the output end of the electric push rod is driven to extend, and a pushing force is applied to the rotating plate through the connecting block. At this time, the rotating plate is driven to rotate downward due to the pushing force, thereby achieving the effect of driving the rotating plate to rotate. Furthermore, the hinge setting facilitates the rotation of the rotating plate.

[0014] The present invention is further configured such that: an L-shaped block is fixedly connected to the output end side wall of the electric push rod, a connecting block two is fixedly connected to one side of the L-shaped block, and a connecting groove two for the connecting block two to slide is provided on the side of the rotating plate away from the connecting groove one.

[0015] By adopting the above technical solution, when the output end of the electric push rod moves, the output end of the electric push rod will drive the L-shaped block to move in the same direction, and drive the connecting block two to move in the same direction along the connecting groove two. By setting the L-shaped block, the stability of the rotating plate can be improved, and the horizontal movement of the rotating plate can be further prevented. At the same time, by setting the connecting block two and the connecting groove two, the connecting block one and the connecting groove one can assist the rotating plate to move.

[0016] The present invention is further configured such that: the output end of the motor is fixedly connected to a mounting plate, and a plurality of mounting blocks are fixedly connected to the grinding disc; both the mounting plate and the mounting blocks are provided with threaded holes, and bolts are fixedly connected in the threaded holes.

[0017] By adopting the above technical solution, when replacing the grinding disc, the bolt is rotated to separate the bolt and the threaded hole from each other. At the same time, the mounting block and the mounting plate are no longer restricted, allowing the grinding disc to be removed from the mounting plate and replaced. After replacement, the threaded holes on the mounting block and the mounting plate are aligned with each other, and then the bolt is screwed into the threaded hole, thus completing the replacement of the grinding disc.

[0018] The present invention is further configured such that: the bottom of the mounting plate is provided with a mounting groove for the mounting block to enter.

[0019] By adopting the above technical solution, the installation positions of the mounting plate and grinding disc can be positioned, and it is also convenient to screw the bolts into the threaded holes.

[0020] The present invention is further provided that a dust cover is fixedly connected to the mounting plate.

[0021] By adopting the above technical solution, the dust raised by the grinding disc during grinding can be reduced, and the dust prevention effect can be improved.

[0022] In summary, the present invention has the following beneficial effects: when replacing the grinding disc, the first drive component and the second drive component can separate the grinding disc from the ground and change the direction of the grinding disc, so that the grinding disc can be replaced without the device body being overturned, reducing the effort required by the operator when replacing the grinding disc and making it easier for the operator to replace the grinding disc.

[0030] A floor grinding device, such as Figures 1-3 As shown, the device includes a main body 1 and a grinding disc 2. A fixed plate 3 is fixedly connected to the main body 1. A groove 4 is formed on the fixed plate 3, and a movable plate 5 is slidably connected within the groove 4. A first drive assembly is provided on the fixed plate 3 to drive the movable plate 5 to move along the groove 4. A rotating plate 6 is rotatably connected to the side of the movable plate 5 away from the fixed plate 3. A second drive assembly is provided on the movable plate 5 to drive the rotating plate 6 to rotate. A motor 7 is fixedly connected to the bottom of the rotating plate 6. The output end of the motor 7 is detachably connected to the grinding disc 2. The output of the motor 7... A mounting plate 18 is fixedly connected to the end of the grinding disc 2, and several mounting blocks 19 are fixedly connected to it. Threaded holes 20 are provided on both the mounting plate 18 and the mounting blocks 19. Bolts 21 are fixedly connected in the threaded holes 20. The bottom of the mounting plate 18 is provided with a mounting groove 22 for the mounting blocks 19 to enter, which can position the mounting plate 18 and the grinding disc 2. At the same time, it is also convenient to screw the bolts 21 into the threaded holes 20. A dust cover 23 is fixedly connected to the mounting plate 18, which can reduce the dust raised by the grinding disc 2 during grinding and improve the dust prevention effect.

[0031] When sanding the floor, motor 7 is started, and the output of motor 7 drives the sanding disc 2 to rotate, thus sanding the floor. When changing the sanding disc 2, the first drive assembly drives the moving plate 5 to move upward along the slide groove 4, and drives the rotating plate 6 and the sanding disc 2 to move in the same direction. At the same time, the sanding disc 2 separates from the floor. Then, the second drive assembly drives the rotating plate 6 to rotate in the direction of the moving plate 5, and drives the sanding disc 2 to rotate. At this time, the sanding disc 2 faces the side away from the fixed plate 3. Then the worker turns... The bolt 21 is moved to separate the bolt 21 from the threaded hole 20. At the same time, the mounting block 19 and the mounting plate 18 are no longer restricted, allowing the grinding disc 2 to be removed from the mounting plate 18 and replaced. After replacement, the mounting block 19 is inserted into the mounting groove 22, and the threaded hole 20 on the mounting block 19 and the mounting plate 18 are aligned. Then, the bolt 21 is screwed into the threaded hole 20. After replacement, the grinding disc 2 is driven back to its original position by the first drive assembly and the second drive assembly, thus completing the replacement of the grinding disc 2.

[0032] like Figures 1-3 As shown, the first driving assembly includes a slider 8 fixedly connected to the side wall of the movable plate 5. The slider 8 and the slide groove 4 are slidably connected. A screw 9 is rotatably connected inside the slide groove 4. The screw 9 and the slider 8 are threadedly connected. A second motor 10 is fixedly connected to the fixed plate 3. The output end of the second motor 10 passes through the fixed plate 3 and is fixedly connected to the screw 9. When the movable plate 5 is driven to move along the slide groove 4, the second motor 10 is started. The output end of the second motor 10 drives the screw 9 to rotate. At the same time, the screw 9 drives the movable plate 5 to move along the slide groove 4. The movable plate 5 is also driven to move in the same direction, thereby achieving the effect of driving the movable plate 5 to move.

[0033] like Figures 1-3 As shown, the second drive assembly includes an electric push rod 11 fixedly connected to the movable plate 5. A connecting block 12 is fixedly connected to the output end of the electric push rod 11. A connecting groove 13 for sliding the connecting block 12 is provided on the side wall of the rotating plate 6. The movable plate 5 and the rotating plate 6 are connected by a hinge 14. An L-shaped block 15 is fixedly connected to the side wall of the output end of the electric push rod 11. The L-shaped block 15 improves the stability of the rotating plate 6 and further prevents horizontal movement. A connecting block 2 16 is fixedly connected to one side of the L-shaped block 15. A connecting groove 2 17 for sliding the connecting block 2 16 is provided on the side of the rotating plate 6 away from the connecting groove 13. The connecting block 2 16 and the connecting groove 2 17 assist the connecting block 12 and the connecting rod 6 in moving horizontally. The connecting groove 13 drives the rotating plate 6 to move. When the rotating plate 6 is driven to rotate towards the moving plate 5, the output end of the electric push rod 11 is driven to retract, and at the same time, the connecting block 12 is driven to move towards the moving plate 5 and along the side wall of the connecting groove 13. The connecting block 12 then applies a pulling force to the rotating plate 6 towards the moving plate 5. At this time, the rotating plate 6 is driven to rotate towards the moving plate 5 due to the pulling force. When the rotating plate 6 is driven back to its original position, the output end of the electric push rod 11 is driven to extend and a pushing force is applied to the rotating plate 6 through the connecting block 12. At this time, the rotating plate 6 is driven to rotate downward due to the pushing force. This achieves the effect of driving the rotating plate 6 to rotate. Furthermore, the hinge 14 facilitates the rotation of the rotating plate 6.

[0034] The working process of this utility model is as follows:

[0035] When sanding the floor, motor 7 is started, and the output of motor 7 drives the sanding disc 2 to rotate, which sands the floor. When changing the sanding disc 2, motor 10 is started, and the output of motor 10 drives the screw 9 to rotate. At the same time, the screw 9 drives the moving plate 5 to move upward along the slide groove 4, and drives the rotating plate 6 and the sanding disc 2 to move in the same direction. At the same time, the sanding disc 2 and the floor separate. Then, the output of the electric push rod 11 is retracted, which drives the connecting block 12 to move towards the moving plate 5 and along the side wall of the connecting groove 13. The connecting block 12 is pulled towards the moving plate 5 by the pulling force. At this time, the rotating plate 6 is driven to rotate towards the moving plate 5 by the pulling force, and drives the sanding disc 2 to rotate. At this time, the sanding disc 2 is facing away from the fixed plate 3. Then, the workers separate the sanding disc 2 from the output of motor 7 and replace the sanding disc 2.

[0036] After replacement, the output end of the electric push rod 11 is extended, and a pushing force is applied to the rotating plate 6 through the connecting block 12. At this time, the rotating plate 6 rotates downward under the influence of the pushing force. Then, the moving plate 5 is driven downward through the screw 9, and the grinding disc 2 is driven back to its original position and comes into contact with the floor. This completes the replacement of the grinding disc 2. Through the setting of the first drive component and the second drive component, the grinding disc 2 can be separated from the ground and the direction of the grinding disc 2 can be changed. Therefore, when replacing the grinding disc 2, the device body 1 does not need to be overturned to replace the grinding disc 2, which reduces the effort required by the staff when replacing the grinding disc 2 and makes it easier for the staff to replace the grinding disc 2.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
