[0002] During the building construction process, a wall grinding device is needed to grind the wall to facilitate the adhesion of the next layer of paint. Although the existing wall grinding devices can replace high-workload practices such as sandpaper grinding, most of the wall grinding devices can only grind flat walls, resulting in a large limitation in the grinding range.

[0003] After retrieval, the prior art publication number CN220806610U discloses a wall grinding device for exterior walls of building construction. The device collects dust through the cooperation of a protective cover arranged outside the grinding disc and a dust collection component. At the same time, an air blowing member guides air downward in the protective cover, so that the dust enters the collection box through the dust discharge pipe and the telescopic pipe. However, this device can only be operated by hand. Therefore, workers need to use ladders to grind high walls, and it is difficult for workers to move during the process of grinding high walls, which affects the grinding efficiency.
