A discharge valve 11 is provided on the outside of the discharge pipe 10. When the discharge valve 11 is opened, the cleaning solution is discharged through the discharge pipe 10.

[0030] refer to Figure 3 、 Figure 4 and Figure 5As shown, a valve 12 is provided on the outside of the delivery pipe 55, and the interior of the guide pipe 54 is connected to a cleaning pipe 13. The cleaning pipe 13 and the three delivery pipes 55 are all equipped with valves 12, which are convenient for controlling the opening and closing respectively, so as to realize the delivery and blocking of different materials.

The outer side of the worm gear 19 is meshed with a worm 20. One end of the worm 20 is rotatably connected to the mounting block 21.

A second motor 23 is provided at one end of the second connecting rod 22. The second motor 23 is installed on the mobile vehicle 1, and its output end is fixedly connected to one end of the second connecting rod 22. The rotation of the control seat 18 can facilitate fine-tuning of the spraying angle. The flexibility of the hose itself can absorb rotation or swing. The delivery pipe 55 and the cleaning pipe 13 are both hoses with a certain excess length and adapt to rotational movement through bending deformation to avoid breakage or leakage due to rigid connection.

[0031] Working principle: When in use, after the paint in the storage barrel 3 is used up, the same kind of paint is conveniently injected through the liquid injection port 44, and the injected paint is filtered through the filter screen 41 to reduce impurities. When the paint in the storage barrel 3 is used up and different paint needs to be injected, a cleaning solution is injected through the liquid injection port 44. Under the drive of the first motor 8, the first connecting rod 7 drives the control rod 6 to rotate, and then the control rod 6 drives the multiple stirring blades 42 to rotate in the storage barrel 3 to stir the cleaning solution, which is convenient for cleaning the inside of the storage barrel 3. The discharge valve 11 is opened to discharge the cleaning solution and residual paint through the discharge pipe 10. The cleaning operation is repeated until the inside of the storage barrel 3 is cleaned and the paint is discharged through the discharge pipe 10. The liquid injection port 44 blows air into the storage barrel 3 to dry the storage barrel 3, making it convenient to inject and store new paint without removing the old barrel and installing a new barrel, thereby promoting the liquid replacement operation. When one of the paints needs to be sprayed, the valve 12 at its delivery pipe 55 is opened, and the cleaning pipe 13 and the valves 12 at the other two storage barrels 3 are closed. Under the drive of the pump body 52, the delivery pipe 55 sucks the paint in the storage barrel 3 and delivers it to the guide pipe 54. The paint is injected into the spray pipe 15 through the connecting pipe 53, so that the paint is sprayed out through multiple nozzles 16 to realize the spraying operation. Under the drive of the second motor 23, the second connecting rod 22 drives the worm 20 to rotate under the support of the mounting block 21, so that the worm gear 1 9 drives the control seat 18 to rotate, and then drives the support frame 51, the connecting plate 17, the spray pipe 15 and the multiple nozzles 16 to rotate, so as to facilitate fine-tuning of the spraying angle and enhance the flexibility of use. The delivery pipe 55 and the cleaning pipe 13 are both hoses with a certain margin length. The flexibility of the hose itself can absorb rotation or swing and adapt to the rotation movement through bending deformation. When the angle of the nozzle 16 is fine-tuned, it does not affect the connection and fixation of the delivery pipe 55 and the cleaning pipe 13. When it is necessary to change to another type of paint for spraying, close the valves 12 at all the delivery pipes 55 and continue spraying until the paint in the delivery pipe 55 is completely sprayed, open the valve 12 at the cleaning pipe 13, and under the drive of the pump body 52, The cleaning solution in the cleaning barrel 14 is transported to the spray pipe 15 through the cleaning pipe 13, the guide pipe 54 and the connecting pipe 53, and is sprayed out through the nozzle 16, so as to clean the previous paint remaining in the guide pipe 54, the connecting pipe 53, the spray pipe 15 and the nozzle 16. After cleaning, the valve 12 at the cleaning pipe 13 is closed, and the cleaning solution in the cleaning pipe 13 is controlled to be sprayed out completely. The valve 12 at the storage barrel 3 where the paint needs to be used is opened. Under the action of the pump body 52, the conveying pipe 55, the guide pipe 54, the connecting pipe 53 and the spray pipe 15, the paint is conveniently sprayed out through the nozzle 16. There is no need to prepare multiple sets of spraying equipment, and frequent installation and disassembly operations are avoided, which reduces the processing cost to a certain extent.
