Wall paint spraying trolley and paint spraying method thereof

The invention relates to a wall paint spraying trolley and a paint spraying method thereof. The moving assembly is mounted at the bottom of the base, and the base can be movably adjusted through the moving assembly; the mechanical arm is mounted on the base, and the position of the tail end of the mechanical arm can be movably adjusted; the paint spraying assembly is mounted at the tail end of the mechanical arm and is used for realizing spraying; and the control module is installed on the base, the control module is in control connection with the moving assembly, the mechanical arm and the paint spraying assembly, and the control module controls the moving path of the base and the moving path of the tail end of the mechanical arm so as to achieve paint spraying construction of the to-be-constructed wall face. Automatic wall surface paint spraying construction is achieved, a person does not need to hold a spray gun to spray paint, time and labor are saved, and the construction efficiency is improved. 本发明涉及一种墙
