Dustproof wall surface grinding machine

Abstract

The invention relates to the technical field of grinding devices, in particular to a dustproof wall surface grinding machine. The dustproof wall surface grinding machine comprises a mounting base, wherein a rectangular groove is formed in the front end of the mounting base, a main shaft is rotationally mounted in the rectangular groove, a grinding disc is fixedly arranged on the main shaft, a connecting pipe is arranged in a driving cavity, a first fan is arranged in a round groove, a dust collecting cavity is further connected with a dust removing mechanism, and a driving mechanism is arranged in the driving cavity. When the machine works, a driving belt is tensioned through a tensioning wheel, so that a first gear and a second gear are meshed; a first tension spring is used for separating the first gear and the second gear so as to prevent a grinding disc from rotating due to the fact that a motor switch is driven by mistake; the grinding disc is attached to the wall surface, the grinding disc is driven to rotate through the driving mechanism, and the grinding efficiency is high; the rectangular groove covers the grinding area, so that dust is prevented from diffusing; and the dust in the rectangular groove is conveyed into the dust collecting cavity through the connecting pipe through the first fan, and enters the dust removal mechanism for dust removal so as to prevent thedust from scattering around.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to a dust-proof wall grinding machine. Background technique [0002] In the field of architectural decoration, the wall surface of buildings is often rough and uneven, which has an adverse effect on subsequent painting processes, such as paint or mud scraping. Therefore, it is necessary to polish the rough and uneven wall surface to facilitate subsequent painting of the wall. Workers generally use sandpaper to polish the wall. When grinding, workers need to wear dust-proof tools such as headgear. The grinding efficiency is very low, and the dust is relatively large during the grinding process, which is easy to cause harm to the human body, and the dust is everywhere. Scattered, and it is not convenient for subsequent cleaning. [0003] Chinese Patent Publication CN 108581679 A discloses a wall sander for building decoration, which includes a main body and a casing. The ca...
