Construction spraying robot

The invention relates to a construction spraying robot, and belongs to the technical field of construction robot tools. The construction spraying robot comprises a crawler walking device, a variable direction paint spraying device, a paint spraying device, a vacuum adsorption device and a chassis. The construction spraying robot also comprises a robot arm. The invention adopts vacuum absorption and cooperates with a crawler walking device to realize the wall climbing function of the construction robot so as to achieve the purpose of automatic walking and spraying of the construction spraying robot. The variable direction paint spraying device and the paint spraying device realizes two painting processes, so that the painting is more sufficient; The paint spraying device has two degrees offreedom and is variable in direction, and can focus on the uneven paint, so that the paint spraying has comprehensiveness and uniformity, and the phenomenon that the paint spraying is not in place canbe avoided. The invention
