DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described below with reference to the accompanying drawings:

[0018] As Figures 1-4 shown, a wall decoration grinding device is composed of a chassis 1, a lifting drive frame 2, a lifting slide frame 3 and a power cover 4;

[0019] The bottom end of the lifting drive frame 2 is fixedly installed on the chassis 1, the lifting slide frame 3 is installed on the lifting drive frame 2 to realize up and down sliding for wall grinding, the power cover 4 is fixedly installed on one side of the lifting slide frame 3, and two groups of grinding rails 5 are fixedly installed on the other side of the power cover 4 and are vertically arranged. The square grinding disc 6 is slidably installed on the grinding rails 5 through the slider 18;

[0020] A grinding motor 21 is installed inside the power cover 4. At the end of the motor shaft of the grinding motor 21, an L-shaped column 22 is installed. On the back side of the square grinding disc 6, a cross-bar groove member 19 is fixedly installed. Inside the cross-bar groove of the cross-bar groove member 19, an in-groove roller 20 is provided. The end of the L-shaped column 22 is rotatably installed into the in-groove roller 20 to drive the square grinding disc 6 to reciprocate up and down for grinding;

[0021] At the bottom of the power cover 4, a dust suction pipe 13 is fixedly installed through an elastic telescopic column 15. A dust collection box 7 is supported and installed on the chassis 1. One end of the dust suction pipe 13 is connected to the top of the dust collection box 7 through a hose 16. The other end of the dust suction pipe 13 is installed with a dust inlet hopper 14 to suck away the dust when it falls during grinding. An air extraction hole is opened on the top box wall of the dust collection box 7. A suction pump 8 is installed on the dust collection box 7. The intake end of the suction pump 8 is installed with a suction pipe 11. The other end of the suction pipe 11 is connected and installed to the air extraction hole.

[0022] As Figures 1-4 shown, the present utility model also discloses the following multiple more optimized specific structures:

[0023] The lifting drive frame 2 is composed of a portal sliding frame 24 and a lifting lead screw 23 rotatably installed inside the portal sliding frame 24. The bottom end of the lifting lead screw 23 is connected and installed with a lifting motor 12. The lifting motor 12 is fixed to the chassis 1. The lifting lead screw 23 is screwed together with the lifting sliding frame 3. The lifting sliding frame 3 is slidably installed on the portal sliding frame 24. In this embodiment, both sides of the portal sliding frame 24 are sliding columns, which is convenient for its sliding installation.

[0024] An exhaust dust-proof mesh cover is covered on the inner hole edge of the air extraction hole to filter the internal dust. A drawer 9 is slidably inserted on the side of the dust collection box 7.

[0025] Foot wheels 17 are installed at the bottom of the chassis 1 for driving the whole device to move.

[0026] The side disc surface of the square grinding disc 6 is provided with an abrasive surface 10, which is convenient for decorative grinding of the wall surface.

[0027] As Figures 1-4 shown, when the wall surface decoration grinding device is in use, the whole device is moved to the wall surface. The lifting motor 12 is started to drive the square grinding disc 6 to move. At the same time, the suction pump 8 and the grinding motor 21 are started. The grinding motor 21 drives the square grinding disc 6 to reciprocate up and down through the L-shaped column 22 and the cross-bar groove member 19 to realize the grinding of the wall surface;

[0028] During the grinding process, the dust is subjected to the force of grinding up and down, and is scattered less. Most of the dust is absorbed through the dust inlet hopper 14 and enters the dust collection box 7 during the falling process. When reaching the bottom of the wall, the dust suction pipe 13 and the dust inlet hopper 14 compress the elastic telescopic column 15 and move upward under the top pressure of the ground, without affecting the grinding of the bottom wall;

[0029] The square grinding disc 6 can achieve grinding through up and down vibration, and can smoothly grind the corner.

[0030] Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
