[0014] The present invention provides a mobile multifunctional wall finishing machine, which has the following beneficial effects:

[0015] 1. The mobile multifunctional wall finishing machine pushes the device close to the wall to be polished, so that the grinding tool is attached to the part to be polished, and the finishing motor drives the transmission gear so that the transmission chain drives the metal crawler to make the grinding tool slide on the wall surface, thereby grinding and finishing the wall. The grinding tool is evenly distributed in a surrounding shape outside the finishing machine box, which is conducive to uninterrupted finishing and polishing of the wall. This setting is conducive to improving the work efficiency of the wall finishing operation, and only one person is needed to operate it, which can effectively reduce the labor intensity of workers and reduce labor injuries.

[0016] 2. The mobile multifunctional wall finishing machine has a snap-fit ​​connection between the grinding tool and the metal track. When the grinding tool is attached to the wall, the pressure from the staff and the rebound pressure from the wall make the connection between the grinding tool and the metal track tighter, thus preventing the grinding tool from falling off. When the grinding tool is away from the wall later, it can be removed by applying force outwards, which makes it convenient to replace the severely worn grinding tool later. It is also convenient to add lubricating oil to the metal track and transmission chain for maintenance later, which is beneficial to extend the service life of the wall finishing machine.

[0017] 3. The mobile multifunctional wall finishing machine, the servo motor drives the lifting gear to rotate clockwise or counterclockwise so that the lifting gear rolls up and down along the lifting rack so that the lifting bracket and the grinding tool slide up and down, which is beneficial to adjust the height of the grinding tool up and down, and is beneficial to trimming the surfaces to be trimmed at different positions of the wall. When the lifting bracket is lifted up and down, the roller connected to the lifting bracket will slide up and down along the slide groove on the side of the vertical rod, which is beneficial to improve the stability of the lifting bracket and the grinding tool sliding up and down.

[0018] 4. For this mobile multifunctional wall finishing machine, the wall board will be attached to the wall first, and then the grinding tool will be attached to the wall. At the same time, the spring telescopic rod will be compressed and contracted so that the wall board and the grinding tool are attached to the wall. When the grinding tool trims the wall and generates dust, the dust-proof net can prevent the dust from escaping. This setting is conducive to collecting the dust and making it fall into the dust collecting box, thereby avoiding dusting, which is conducive to improving a good working environment and preventing workers from inhaling dust and causing damage to their bodies.

[0019] 5. The mobile multifunctional wall finishing machine has a movable baffle bottom that is movably connected to the bottom of the front end of the dust collecting box, and the rubber sheet is a flexible structure, and one end of the rubber sheet is fixed to both sides of the inner wall of the dust collecting box, and the other end of the rubber sheet is fixed to the two ends of the inner side of the movable baffle, so that the movable baffle has an inclined structure, and the movable baffle movably connected to the bottom of the front end of the dust collecting box will stick to the wall to receive dust so that the dust slides into the dust collecting box, and the card slot at the bottom of the dust collecting box is inserted into the card strip on the upper surface of the support strip, so that the dust collecting box is connected to the upper surface of the support strip. This arrangement is convenient for disassembly and assembly of the dust collecting box at a later time, and convenient for cleaning the dust and garbage inside the dust collecting box at a later time.

By pushing the handle 17 to make the grinding tool 15 close to the wall or away from the wall, the trimming depth can be controlled. This setting is conducive to improving the work efficiency of the wall trimming operation, and only one person is required to operate it, which can effectively reduce the labor intensity of workers and reduce labor injuries. When the grinding tool 15 trims the wall and dust falls, the dust-proof net 1610 can prevent the dust from escaping. This setting is conducive to collecting the dust and making it fall into the dust box 1603, thereby avoiding dusting, which is conducive to improving a good working environment and preventing workers from inhaling dust and causing damage to their bodies. Since the card slot 1604 at the bottom of the dust box 1603 is stuck in the card strip on the upper surface of the support strip 1602 1605, so that the dust box 1603 is connected to the upper surface of the support bar 1602, and then the dust box 1603 can be removed by lifting it up, which is convenient for cleaning the dust and garbage inside the dust box 1603 in the later stage. Finally, the grinding tool 15 and the metal track 14 are connected in a snap-fitting manner. When the grinding tool 15 is attached to the wall, the pressure pushed by the staff and the pressure rebounded by the wall make the connection between the grinding tool 15 and the metal track 14 tighter, avoiding the falling off of the grinding tool 15. When the grinding tool 15 is away from the wall in the later stage, the grinding tool 15 can be removed by applying force outwards, so as to facilitate the replacement of the severely worn grinding tool 15 in the later stage, and also facilitate the addition of lubricating oil to the metal track 14 and the transmission chain 12 for maintenance in the later stage.This is beneficial to prolonging the service life of the wall finishing machine.
