[0001] The present application relates to the technical field of concrete surface coating tests, and in particular to a concrete surface coating device. Background Art

[0002] At present, with the rapid development of the modern construction industry, concrete surface treatment technology has received extensive attention and application. Research and testing in the laboratory are important links in promoting the advancement of this technology. Traditional methods mainly rely on manual brushing or simple spray gun operation. Although they can achieve the coating effect to a certain extent, they have obvious shortcomings in efficiency, uniformity and quality control. In order to improve the quality and efficiency of construction, we are committed to developing more automated coating devices, which not only increase the construction speed, but also significantly improve the uniformity and adhesion of the coating layer.

[0003] In order to solve the problem of coating on the concrete surface in the laboratory, the existing technology is manual spraying, that is, spraying by hand-held spray gun.
