Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to a wall coating device for construction engineering. Background Art

[0002] In construction projects, after the main structure of the building is completed, the outer surface of the wall needs to be painted. During decoration, after the putty is scraped on the wall inside the house, some owners will also paint the surface of the putty on the wall with latex paint. The prior art is to use a brush roller dipped in paint to roll on the wall surface, or directly spray on the wall surface. If a brush roller is used for rolling, the brush roller needs to dip the paint in the paint bucket frequently. During the transfer process, the paint on the brush roller will fall to the ground, causing waste, and will also pollute the construction environment. The brush roller rolling on the wall is prone to sagging, resulting in uneven painting quality; if the spraying method is used, it will cause pollution to the construction environment, the thickness of the paint on the wall is thin, and the painting quality of the wall is poor.

[0003] A Chinese patent (CN112761334A) discloses a slurry coating device for construction engineering. The technical solution of the patent is to rotate and connect a coating roller at the top of a fixed plate, and set a spray plate below. A nozzle is set on the spray plate. During use, the coating is sprayed onto the coating roller through the nozzle and then rolled on the wall. The coating is sprayed onto the coating roller instead of the wall, and the aerosol coating will still cause construction environmental pollution and waste. Utility Model Content
