Such a formed film is generally called a coating film, also known as a paint film or a coating layer." During the construction of a mine, in order to create an intelligent, efficient and high-standard mine, at present, the standardized work of the roadway walls and ground enclosures in the mining area cannot be achieved, and it is not beautiful. When the existing paint spraying device is in use, since the position and angle of the spray head of the paint spraying device are fixed and cannot be flexibly turned, many corners are not easy to spray.

The motors 212, 231 and 241 serve as power mechanisms and can drive the fixedly connected gears 213, 232 and 242 to rotate, so that the racks 230, 240 and 250 outside the meshing gears 213, 232 and 242 drive the fixedly connected second spray pipe 23, third spray pipe 24 and nozzle 25 to rotate. Since the nozzle 25 can change the direction of paint spraying, making the spraying angle in the vertical direction, and the second spray pipe 23 can change the angle of the nozzle 25 in the vertical direction again after the nozzle 25 is in the vertical direction, the spraying angle of the nozzle 25 can be changed multiple times, expanding the sprayable construction range.

[0025] Please refer to Figures 1-6 , the portable component 1 includes a paint bucket 11, a control handle 12 is fixedly connected to the side surface of the paint bucket 11, an air inlet pipe 14 is fixedly connected to one end at the bottom of the control handle 12, a pressure pipe 16 is fixedly connected to the other end at the bottom of the control handle 12, a support plate 19 is fixedly connected to the inner cavity bottom of the paint bucket 11, a rotating shaft 18 is fixedly connected to the top of the support plate 19, a stirring blade 17 is sleeved outside the rotating shaft 18, a key 13 is movably connected to the control handle 12, a bucket cover 15 is arranged on the top of the paint bucket 11, air enters through the air inlet pipe 14 and reaches the pressure pipe 16 through an air pressure regulating valve, an air switch valve and a fan-shaped regulating valve arranged inside the control handle 12, and the paint enters the inside of the spray pipe 21 from the feeding port 22 under the action of gravity.

[0026] Please refer to Figure 1 , 3-6. There are holes at the top of the nozzle 21 and a feeding port 22 extends upward. One end of the nozzle 21 is fixedly connected with a connecting piece 211, and the connecting piece 211 is fixedly connected with the pressure pipe 16.

[0027] When in use, when it is necessary to change the spraying direction of the spray head 25 according to the spraying environment, first, the third motor 241 drives the top third gear 242 to rotate, so that the third rack 250 meshing on the surface of the third gear 242 drives the spray head 25 to rotate. At the same time, the second motor 231 drives the second gear 232 arranged at the top to rotate, so that the second rack 240 meshing on the surface of the second gear 232 changes the rotation direction of the spray head 25 again.

Since the paint is contained in the paint bucket 11, during operation, air enters the inside of the control handle 12 through the air inlet pipe 14, and then reaches the pressure pipe 16 through the air pressure regulating valve, air switch valve, and fan-shaped regulating valve arranged inside the control handle 12. The paint enters the inside of the nozzle 21 from the feeding port 22 under the action of gravity. Press the button 13 to open the paint needle valve, and the paint is atomized by air pressure and sprayed on the part that needs to be painted.
