Multiple air ducts 12 are fixedly connected to the inner side wall of the processing frame 3. All the multiple air ducts 12 are communicated with the air flow cavity;

[0026] The pressing plate 6 is connected with a grinding mechanism through a driving mechanism. The grinding mechanism includes a rotating shaft 14 rotatably connected to the inner side wall of the processing frame 3. A grinding roller 16 is fixedly sleeved on the outer side wall of the rotating shaft 14.

[0028] The specific working principle of the present utility model is as follows:

[0029] In the initial state, the device is moved to the working location. By lifting and lowering the first telescopic rod 2, the height of the processing frame 3 is adjusted. Then the second telescopic rod 5 works to drive the pressing plate 6 to move up and down, and further drives the mounting plate 13 to move up and down. The up and down movement of the mounting plate 13 drives the rack to move up and down. Then, in the cooperation of the rack and the gear 15, the rotating shaft 14 rotates, and further drives the grinding roller 16 to rotate, so as to grind the part of the box-type substation shell that needs to be painted;

[0030] After grinding, the device is moved to the left in the direction shown in the figure to avoid the grinding roller 16 contacting the box-type substation shell. The servo motor 17 is started to work. The working mode of the servo motor 17 is the prior art and will not be elaborated in detail here. The servo motor 17 drives the output shaft 18 to rotate, and further makes the moving block 19 move, driving the spray head 20 to spray the box-type substation shell. The spray head 20 is the prior art and will not be elaborated in detail here;

[0031] After the painting is completed, continue to work through the second telescopic rod 5. While the second telescopic rod 5 is working, it drives the pressing plate 6 to move up and down. The up and down movement of the pressing plate 6 drives the sliding plate 7 to move downward. When the sliding plate 7 moves downward, the gas in the air box 4 is squeezed. The gas enters the air flow cavity through the first air flow pipe 9, the sleeve 10 and the second air flow pipe 11, and then is discharged from the air pipe 12. When the sliding plate 7 moves upward, a negative pressure is formed inside, and then it will inhale air. At the same time, the air flow at the air pipe 12 is accelerated. By blowing and inhaling air through the air pipe 12, the air flow is accelerated, and the drying of the box transformer shell after painting is accelerated, avoiding the phenomenon of paint dripping caused by the paint not drying for a long time at the painting area.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
