[0044] The guide rail 6 has two sliding grooves 24 on its surface. The moving block 4 is connected to a cleaning rod 25 and two pulleys 26 on one side. Each pulley 26 can roll in the corresponding sliding groove 24. One end of the cleaning rod 25 is located in the sliding groove 24 and is in contact with the bottom surface of the sliding groove 24.

[0045] One end of the support rod 3 is connected to an adjusting worm gear 27, one side of the adjusting worm gear 27 is engaged with an adjusting worm 28, one end of the adjusting worm 28 is connected to an adjusting motor 29, the end of the support rod 3 away from the adjusting worm gear 27 is connected to a stabilizing rod 30, one end of the stabilizing rod 30 is rotatably connected to a rotating component 31, and the rotating component 31 is connected to the moving block 4.

[0046] The connecting part includes a connecting shell 32, a connecting plate 33, a fixing rubber pad 34, and a guide rod 35. The connecting plate 33 is located below the connecting shell 32. The fixing rubber pad 34 is connected to the connecting plate 33 and is located inside the connecting plate 33. The guide rod 35 is connected to the connecting shell 32 and is located through the connecting plate 33. The connecting plate 33 can move along the direction of the guide rod 35.

[0047] One side of the connecting plate 33 is connected to a connecting rod 36. The end of the connecting rod 36 away from the connecting plate 33 is connected to a rack 37. A connecting gear 38 is meshed on one side of the rack 37. A central rod 39 is rotatably connected inside the connecting shell 32. The central rod 39 is connected to and passes through the connecting gear 38. A connecting worm gear 40 is provided above the connecting gear 38. The connecting worm gear 40 is connected to and wraps around the central rod 39. A connecting worm 41 is meshed on one side of the connecting worm gear 40. One end of the connecting worm 41 is rotatably connected to the inner wall of the connecting shell 32, and the other end is connected to a transmission rod 42. One end of the transmission rod 42 is connected to a knob 43, and the knob 43 is located on the outside of the connecting shell 32.

[0048] Among them, the rack 37 and the connecting rod 36 are an inseparable integral structure, and the rack 37 is perpendicular to the connecting rod 36.

[0049] The connecting shell 32 has a canopy fixing rod 44 on its upper part, a plug rod 45 on one side of the connecting shell 32, the plug rod 45 has an external thread on its outer surface, a connecting hole 46 on one side of the connecting shell 32, the inner wall of the connecting hole 46 has an internal thread, and the internal thread of the inner wall of the connecting hole 46 is compatible with the external thread on the outer surface of the plug rod 45. The end of the canopy fixing rod 44 that is inserted into the connecting shell 32 has an installation hole 47, and the installation hole 47 is compatible with the plug rod 45.

[0050] The stirring motor 8 drives the first stirring rod 9 to rotate. The first stirring rod 9 can drive the second stirring rod 12 to rotate through the first gear 10 and the second gear 11. The rotation of the first stirring rod 9 and the second stirring rod 12 can stir the paint stored in the storage tank 5, thereby ensuring that the adhesive components are mixed evenly and the sprayed adhesive has a uniform concentration.

[0051] The storage capacity of the equipment is increased by setting up storage boxes and storage hooks 17, which facilitates construction.

[0052] When installing the guide rail 6, the L-shaped plate 7 is clamped above the outer guardrail, and the fixing rod 51 is rotated to clamp the outer guardrail with the L-shaped plate 7, thereby achieving the purpose of fixing the guide rail 6.

[0053] During the spraying operation, the feed pipe 2 is connected to the feed pipe 15. The spray pump 14 draws the paint from the storage tank 5 into the feed pipe 15 through the discharge pipe 13, and sprays the paint out through the nozzle 1. The sprayed paint will cover the entire area to be sprayed, and there will be no blind spots. The drive motor 22 drives the moving gear 19 to rotate through the drive gear 21. Since the moving gear 19 meshes with the toothed plate 18, it can drive the moving plate to move along the guide rail 6 when it rotates. At the same time, the pulley 26 rolls in the sliding groove 24, which can improve the stability of the moving block 4 when it moves. And the cleaning rod 25 can clean the sliding groove 24 when it moves, so that the pulley 26 rolls more smoothly in the sliding groove 24. In this way, the moving block 4 drives the nozzle 1 to move through the support rod 3, which improves the spraying efficiency.

[0054] When the spraying work is completed and the staff inspects the spraying effect, the adjusting motor 29 can drive the adjusting worm wheel 27 to rotate by adjusting the worm 28. The rotation of the adjusting worm wheel 27 can drive the support rod 3 to rotate until it is parallel to the guide rail 6. When the staff inspects the spraying effect, they will not be blocked by the support rod 3, which facilitates the inspection work. In addition, during the rotation, the stabilizing rod 30 can rotate with the assistance of the rotating part 31, which improves the stability of the support rod 3 when it rotates.

[0055] When the connecting shell 32 is installed on the moving block 4, rotating the knob 43 drives the connecting worm 41 to rotate via the transmission rod 42. The rotation of the connecting worm 41 drives the connecting worm wheel 40 to rotate. The connecting worm wheel 40 drives the connecting gear 38 to rotate via the central pivot. The rotation of the connecting gear 38 drives the rack 37 to move. Thus, the connecting plate 33 can be moved along the direction of the guide rod 35 via the connecting rod 36, so that the fixing rubber pad 34 fits against the moving block 4. This achieves the overall fixing of the connecting shell 32 above the moving block 4, improving the efficiency of fixing the connecting shell 32.

[0056] When connecting the connecting shell 32 to the external canopy, first fix the canopy fixing rod 44 to the canopy 48, then insert the canopy fixing rod 44 into the connecting shell 32, and rotate the insertion rod 45. With the cooperation of the internal thread on the inner wall of the connecting hole 46 and the external thread on the outer surface of the insertion rod 45, the insertion rod 45 is inserted into the mounting hole 47 at the lower end of the canopy fixing rod 44, thus completing the fixing of the canopy fixing rod 44.

[0057] In summary, the continuous stirring of the coating material in the storage tank 5 by the first stirring rod 9 and the second stirring rod 12 ensures uniform mixing of the binder components and uniform concentration of the sprayed binder. At the same time, the moving block 4 drives the nozzle 1 to move along the guide rail 6, achieving no blind spots during spraying, improving the quality and efficiency of spraying. After spraying, the support rod 3 is rotated to be parallel to the guide rail 6, which facilitates subsequent inspection of the sprayed area by the staff. In addition, the connecting shell 32 is fixed above the moving block 4 by rotating the knob 43, and the external canopy 48 is fixed above the connecting shell 32 by the insertion rod 45 and the canopy fixing rod 44, which improves the efficiency of installing and removing the connecting shell 32 and the efficiency of installing the canopy 48, and improves the quality of spraying work in thunderstorms.

[0058] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
