[0031] Reference Figures 1-3, An embodiment provided by the present utility model: A film spraying device applicable to a liquid film, including a film spraying vehicle 1 and a plurality of nozzles 20. A liquid storage cylinder 2 is fixedly connected to the left side of the top of the film spraying vehicle 1. Two liquid infusion pipes 3 are fixedly connected to the left side of the top of the liquid storage cylinder 2. A liquid storage cylinder 2 is fixedly connected to the left side of the top of the film spraying vehicle 1, and two liquid infusion pipes 3 are fixedly connected to the liquid storage cylinder 2 for transporting liquid film liquid. Two support plates 4 are fixedly connected to the left side of the top of the film spraying vehicle 1. Motors 5 are fixedly connected to the top ends of the two support plates 4 on the far sides, and the two support plates 4 support the motors 5.

[0032] Reference Figure 2 , Figure 3 , The driving end of the motor 5 is fixedly connected to a rotating shaft 6. A support plate 7 is fixedly connected to the middle of the far sides of the two support plates 4. The left side of the support plate 7 is slidably connected to the outside of the rotating shaft 6. The right end of the support plate 7 is rotatably connected to a rotating rod 8. One end of the rotating rod 8 away from the support plate 4 is rotatably connected to a connecting rod 9. The left side of the connecting rod 9 is fixedly connected to a cross tube 10. A support member 11 is fixedly connected to the top end of the outside of the rotating shaft 6, and a fixing rod 12 is fixedly connected to the bottom end of the outside of the rotating shaft 6. The driving end of the motor 5 is fixedly connected to the rotating shaft 6. The fixing rod 12 and the support member 11 fixedly connected to the rotating shaft 6 rotate synchronously with the motor 5. The support plate 7 on the support plate 4 is slidably connected through the outside of the rotating shaft 6, and the rotating rod 8 is fixedly connected to the cross tube 10 through the connecting rod 9.

[0033] A driving gear 13 is fixedly connected to the top end of the outside of the cross tube 10. The top end of the driving gear 13 is rotatably connected to the bottom end of the end of the support member 11 away from the support plate 4. The top end of the cross tube 10 is rotatably connected to the middle of the end of the support member 11 away from the support plate 4. The bottom end of the cross tube 10 is rotatably connected to the middle of the end of the fixing rod 12 away from the support plate 4. Since the support plate 7 is fixed to the support plate 4, and the connecting rod 9 to which the cross tube 10 is fixed is at a fixed angle, and the driving gear 13 is also limited at the top end of the outside of the cross tube 10, so when the support member 11 and the fixing rod 12 rotate, the rotating rod 8 will pull the cross tube 10 and the driving gear 13 through the connecting rod 9 to be limited to rotate in the middle of the fixing rod 12 and the support member 11.

[0034] In the middle of the cross-shaped pipe 10, there is a rotating assembly for folding multiple nozzles 20. The rotating assembly includes a limiting rod 14, a driven gear 15, a positioning member 16, and a spraying frame 17. The outer part of the limiting rod 14 is rotatably connected to the inner wall of the middle part of the cross-shaped pipe 10. The inner wall of the middle part of the cross-shaped pipe 10 is rotatably connected to the limiting rod 14. The left side of the limiting rod 14 is fixedly connected to the driven gear 15. The external teeth of the driven gear 15 are meshed with the external teeth of the driving gear 13. The driven gear 15 drives the spraying frame 17 to fold upward through the meshing connection of its external teeth with the driving gear 13. The left side of the driven gear 15 is fixedly connected to the positioning member 16. The left side of the positioning member 16 is fixedly connected to the spraying frame 17. The left end of the infusion pipe 3 is fixedly connected to the middle part of the right side of the spraying frame 17.

[0035] Reference Figure 1 and Figure 4 , a plurality of connecting sleeves 18 are fixedly connected to the bottom end of the spraying frame 17. Card slots 19 are formed on both the left and right sides of the connecting sleeve 18. A plurality of connecting sleeves 18 are fixed to the bottom end of the spraying frame 17. Each connecting sleeve 18 is provided with an open card slot 19. The card slot 19 is in a shape similar to a hook. Thread patterns 21 are provided at the outer bottom end of the nozzle 20. A sleeve 22 is threadedly connected to the outside of the thread patterns 21. The nozzle 20 is designed such that the sleeve 22 can be installed and fixed to different types of card slots 19. Both the left and right sides of the sleeve 22 are fixedly connected with clamping posts 23. The outside of the sleeve 22 is engaged with the inner wall of the connecting sleeve 18. The outside of the clamping post 23 is slidably connected to the inner wall of the card slot 19. The sleeve 22 is fixedly connected with the clamping post 23. The clamping post 23 is engaged with the inner wall of the connecting sleeve 18 for quickly disassembling and installing the nozzle 20.

[0036] Working principle: When the user does not need to use the spraying film vehicle 1, the motor 5 fixed to the support plate 4 can be started to drive the rotating shaft 6 to rotate by the motor 5. The rotating shaft 6 drives the fixed rod 12 and the support member 11 fixed to the rotating shaft 6 to rotate synchronously. At this time, since the support plate 7 is fixed to the support plate 4 and the connecting rod 9 fixed to the cross-shaped pipe 10 is at a fixed angle, and the driving gear 13 is also limited at the outer top end of the cross-shaped pipe 10. Therefore, when the support member 11 and the fixed rod 12 rotate, the rotating rod 8 will pull the cross-shaped pipe 10 and the driving gear 13 through the connecting rod 9 to rotate and be limited in the middle of the fixed rod 12 and the support member 11, so that the external teeth of the driving gear 13 drive the external teeth of the driven gear 15 to rotate. Thus, the driven gear 15 drives the spraying frame 17 to rotate upward and fold and store it at the rear side position of the left end of the spraying film vehicle 1 through the positioning member 16, realizing that the spraying frame 17 can be folded compactly when not in use, saving storage and transportation space.

[0037] When the user needs to replace the card slot 19 or clean and maintain the card slot 19, the spray head 20 and the sleeve 22 can be rotated to make the clamping post 23 of the sleeve 22 slide in the card slot 19 of the connecting sleeve 18, so that the clamping post 23 can move along the sliding route of the card slot 19, and the sleeve 22 and the spray head 20 can be disengaged from the clamping of the connecting sleeve 18. By operating in the reverse direction, the spray head 20 can be quickly installed, and the card slot 19 can be quickly disassembled and installed, so as to facilitate the replacement of different types of spray heads 20 to meet different ground coating requirements.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
