Paint spraying device and method for construction site

Abstract

The invention discloses a paint spraying device for a construction site. The paint spraying device comprises a shell, a spraying mechanism, an air injection mechanism and a transmission mechanism, wherein two handles used for holding are arranged at the bottom of the shell, the spraying mechanism is mounted in the shell, so that paint and compressed air are mixed and sprayed out, the air injection mechanism is mounted on the outer side of the spraying mechanism, so that floating ash on the wall surface is blown away by the spraying mechanism before paint spraying, the transmission mechanism is installed in the shell, and when the transmission mechanism moves, the spraying mechanism and the air injection mechanism work synchronously, floating ash on the wall surface is blown away, and paint spraying is conducted. According to the paint spraying device, the spraying mechanism is combined with the air injection mechanism to spray paint on the wall surface, dust needs to be removed on the part, needing to be sprayed, of the wall surface while spraying is conducted, therefore dust on the spraying portion is reduced, even if the wall surface is not completely cleaned, the air injection mechanism can also clean the wall surface in advance, so that the spraying effect of the wall surface is ensured, the time for repairing paint on the wall surface is shortened, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a painting device and method for a construction site. Background technique [0002] Coatings are applied on the surface of objects, which can bond well with the base material and form a complete and tough protective film. They are called architectural coatings. Coatings and paints are the same concept. Paint is a customary name that has been used for a long time. Has been used in the construction industry. [0003] When spraying paint on the building wall, use the gun head to spray the paint directly on the wall. Before painting, the wall needs to be roughened, and then the floating dust on the wall should be cleaned, and finally the paint is sprayed on the wall. However, during the wall cleaning process, due to the same color of the wall, some positions may be missed when the construction personnel clean up, resulting in the wall not being completely cleaned, a...

[0003] When spraying paint on the building wall, use the gun head to spray the paint directly on the wall. Before painting, the wall needs to be roughened, and then the floating dust on the wall should be cleaned, and finally the paint is sprayed on the wall. However, during the wall cleaning process, due to the same color of the wall, some positions may be missed when the construction personnel clean up, resulting in the wall not being completely cleaned, and there is a lot of dust on the construction site. , Part of the dust in the air will adhere to the cleaned wall, which may lead to unqualified spray paint on the dust-attached wall and need to be repainted, which will waste spraying time, increase labor costs, and cause color difference on the wall. Affect the aesthetics of the wall
