Spraying robot for wind power blade

The invention relates to a spraying robot for a wind power blade. The spraying robot comprises a moving device, a spraying executing mechanism and a mechanical arm. The spraying executing mechanism and the mechanical arm are both arranged on the moving device. The spraying executing mechanism comprises a driving end and an executing end; the driving end is connected with the execution end; the execution end comprises a spraying mechanism connecting plate, a side inclined rotating bottom plate, a double-spraying cavity and a porous gas exhaust. Spraying of the wind power blade is achieved through cooperation of the spraying executing mechanism and the moving device, meanwhile, the side inclination angle between the spraying mechanism connecting plate and the side inclination rotating bottom plate and the pitching angle between the rotating support and the side inclination rotating bottom plate are controlled through the driver, and therefore comprehensive spraying of the blade is achieved; and due to the arran
