The present invention provides a wheel spraying device, comprising a frame, an electric motor, a hollow shaft, a ring flange, and cylinders. During use of the device, the need of jacking up and rotating a wheel in wheel spraying can be met, and the difficulty of removing the protection plugs of bolt hole due to thickening and clogging after completion of spraying can be completely avoided. Meanwhile, the device has the characteristics of simple structure, convenience for use, low manufacturing cost, and safe and stable performance.
