Description

Technical Field

[0001] The utility model relates to the technical field related to building construction, in particular to a wall grinding machine for building construction. Background Art

[0002] Wall grinding machine can also be called "wall grinding machine", "wall sanding machine", "wall grinding machine", "putty grinding machine" and "polishing machine", which vary depending on the place.

[0003] The utility model patent with announcement number CN220944480U discloses a wall grinding machine for construction, which belongs to the technical field related to construction, and aims to solve the problem that the wall grinding technology in the current decoration industry in the prior art has always remained in the traditional manual operation. The decoration workers use sandpaper or a simple wall grinding machine to grind the wall, which is not only inefficient, but also the fatigue and dust caused by long-term work seriously damage human health. For example, dust with a particle diameter of 0.5 mm can directly reach the lungs through the respiratory tract and precipitate, making people prone to silicosis. The utility model patent includes a lower base, and the upper part of the lower base is provided with an electric telescopic rod 1, and the upper part of the electric telescopic rod 1 is provided with an upper base. In the utility model, the output end of motor 1 drives shaft 1 to rotate, and then shaft 1 drives gear 2 to rotate, so that the support rod drives the entire wall grinding assembly to rotate, and the inclination angle of connecting rod 1 can be adjusted by electric telescopic rod 2, so as to achieve the angle adjustment of the wall grinding assembly, and the wall grinding assembly includes motor 2, and then motor 2 drives pulley 1 to rotate, so that pulley 2 is driven by the V-belt to rotate, so that shaft 3 drives the entire wall grinding assembly to rotate, and the wall grinding assembly is fixed by the supporting feet on the upper part of the fixed seat, so as to ensure the stability of the entire equipment in the wall grinding, and then the motor 3 drives the grinding head to rotate to realize the wall grinding function, thereby improving the quality of wall grinding.

[0004] However, the above patent still has shortcomings: although the patent realizes the wall grinding function by driving the grinding head to rotate by the motor, it does not have the function of replacing the grinding head. When grinding the wall, the roughness of the grinding head gradually decreases due to long-term friction with the wall, so it is necessary to stop the machine and replace the grinding head. The disassembly method of the grinding head of this wall grinding machine is relatively cumbersome, which greatly reduces the efficiency of grinding. Utility Model Content
