The utility model relates to the technical field of stone sculpture processing, in particular to a coating device for a stone sculpture surface protective coating, which comprises a spraying room and a plate trailer slidably arranged on a guide rail, an upper winding roller and a lower winding roller are rotatably arranged above and below an opening in the front end face of the spraying room respectively, a piece of rolling cloth is wound between the upper winding roller and the lower winding roller, and the rolling cloth is provided with a rectangular opening and a guide plate. A transverse plate with an operation round hole and an observation window is transversely arranged on the guide plate in a sliding mode, during operation, a worker observes from the outside through the observation window, and the two arms penetrate through the round hole to enter a spraying room to operate a spraying gun. According to the device, an arm can freely move up and down through winding and unwinding of the rolled cloth, left-right movement is achieved through sliding of the transverse plate, the operation space is greatly expanded, the spraying requirement of medium and large stone sculptures is easily met, operation fatigue is relieved through cooperation with a balancing weight, multiple sealing is achieved through combination with a guide piece, a pressing rod and an oversleeve, harmful gas is thoroughly isolated, and human health is guaranteed.
