Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering construction, and more specifically relates to a coating spraying device for building engineering. Background Art

[0002] Architecture is the most basic spatial environment for human daily life. Architectural art is a comprehensive practical plastic art formed by aesthetic treatment of building group organization, building shape, plane layout, three-dimensional form, structural modeling, internal and external space combination, decoration and decoration, color, texture, etc. During the construction process, it is necessary to spray protective coatings on the walls to improve the protective performance of the walls, or spray colored coatings on the walls to increase the artistic quality of the building. Most of the existing spraying equipment directly injects the paint into the spray tank, and the manual handheld spraying equipment is used to spray the building wall, which consumes a lot of physical energy for the operator. In addition, the weight of the spraying equipment plus the paint is large, which makes the operator's hand shake easily after a period of spraying, which affects the spraying effect. In addition, the spraying efficiency is low, and large-area rapid spraying is impossible. CN108915218A discloses a construction paint spraying device, which sprays the wall surface through a movable base and a spray gun, but the spray gun still needs to be held by the operator for spraying. Due to the weight of the spray gun itself and the recoil of the spraying, the spraying effect of the operator is still affected, and the problem of manpower consumption is not solved. Therefore, how to provide an efficient, convenient and easy-to-operate construction engineering paint spraying device is a problem that technicians in this field need to solve urgently.
