Description

Technical Field

[0001] The present application relates to the technical field of building decoration equipment, and more specifically, to a dust-free grinding equipment for building decoration walls. Background Art

[0002] In building decoration, especially interior decoration, an indispensable procedure is wall whitening. The most commonly used wall whitening method in the prior art is to scrape putty. However, after the putty is scraped on the wall, the surface is prone to unevenness. The wall needs to be polished to achieve a certain smoothness, so a wall grinder is needed.

[0003] After searching, the publication (announcement) number CN214109839U discloses a dust-free wall grinder for building decoration and decoration, including a casing, and an air suction hood is arranged on the front side of the casing... This application arranges the air suction hood so that when grinding, the air suction hood fits tightly against the wall, making the grinding space relatively sealed. At the same time, a dust suction pipe, a dust collecting box and a vacuum cleaner are arranged at the bottom end of the air suction hood, so that the vacuum cleaner can use the dust to suck the dust into the dust collecting box during the rotation of the grinding disc, thereby effectively improving the dust suction effect of the grinder, avoiding dust flying and affecting the health of construction workers. However, this application relies on the staff to grind the wall with handheld grinding equipment. When the wall to be polished is higher than the height of the staff, the staff needs to use the help of other tools to grind to the wall at a higher position. Relying on other tools will increase the workload of the staff and is inconvenient.

[0004] In order to solve the above problems, the present application provides a dust-free polishing device for building decorative walls. Utility Model Content

[0017] Through the above technical solution, when it is necessary to grind the lower part of the wall, the limit bolts and the fixing bolts can be unscrewed to release the limits on the mounting block and the insert block respectively, and the grinding assembly can be removed, and then the wall can be grinded by hand.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. The control motor drives the rotating column to rotate, the rotating column drives the gear to rotate, the gear drives the rack plate to move upward, the rack plate moves upward to adjust the height of the grinding assembly, which is convenient for workers to grind the walls that are out of reach, and improves the application range of the device, so there is no need to use other tools, reducing the workload of the staff, and making it more convenient to use.
