The air jet is fixed to the bottom of the second hydraulic cylinder 12 and is connected to the drying fan 14.

[0045] Further reference Figure 1 , 3 4, 5, The adjustable swing part includes a shaft 43, which is located inside the housing 9 and at the top of the housing 9. The two ends of the shaft 43 are rotatably connected to a first fixed seat, which is fixedly connected to the inner wall of the housing 9. A sleeve 41 is sleeved on the shaft 43. Several limiting blocks 42 are fixedly connected to the outer wall of the shaft 43. A limiting groove is opened on the inner wall of the sleeve 41, and the limiting blocks 42 slide with the limiting groove. A frame 33 is fixedly connected to the bottom end of the sleeve 41, and the nozzle 8 is fixedly connected to the bottom end of the frame 33. An adjustment component is provided above the sleeve 41, which is fixedly connected to the first fixed seat and screwed to the sleeve 41. A drive component is provided below the sleeve 41, which is connected to the frame 33 in a transmission manner.

[0046] Further reference Figure 4 , 5 The adjustment assembly includes a screw 39 and a crank handle 44. A fixing plate 37 is fixedly connected to the top of the first fixing seat. An arc-shaped groove is provided on the fixing plate 37. An arc-shaped block 38 is slidably connected to the fixing plate 37 through the arc-shaped groove. The screw 39 is located between the two arc-shaped blocks 38. The two ends of the screw 39 are rotatably connected to the two arc-shaped blocks 38 respectively. One end of the screw 39 extends out of the housing 9 and is fixedly connected to the crank handle 44. A threaded sleeve 40 is fixedly connected to the top of the sleeve 41. The threaded sleeve 40 is threaded onto the screw 39.

[0047] Furthermore, the side wall of the housing 9 is provided with an arc-shaped hole, which is adapted to the arc-shaped groove, and the screw 39 extends out of the housing 9 through the arc-shaped hole.

[0048] Further reference Figure 1 , 3The drive assembly includes a connecting seat 34, a limiting rod 36, a spherical block 35, and a second motor 10. The connecting seat 34 is slidably connected to the frame 33, and a spherical cavity is formed inside the connecting seat 34. The spherical block 35 is slidably connected to the spherical cavity. Both sides of the connecting seat 34 have flared grooves that communicate with the spherical cavity. Both sides of the frame 33 are provided with second fixed seats, which are fixedly connected to the inner wall of the housing 9. The first connecting frame 11 and the second connecting frame 32 are rotatably connected to the two second fixed seats respectively. The limiting rod 36 is located between the first connecting frame 11 and the second connecting frame 32. Both ends of the limiting rod 36 are fixedly connected to the first connecting frame 11 and the second connecting frame 32 respectively. The limiting rod 36 is inclined and located below the sleeve 41. The limiting rod 36 slides through the spherical block 35. The second motor 10 is fixedly connected to the outer wall of the housing 9, and the output shaft of the second motor 10 is fixedly connected to the first connecting frame 11.

[0049] The second motor 10 operates, driving the first connecting frame 11 to rotate. Since the limiting rod 36 is fixedly connected to the first connecting frame 11 and the limiting rod 36 is inclined, the movement trajectory of the limiting rod 36 is a conical structure. Since the connecting seat 34 is slidably connected to the frame 33, and the frame 33 is fixedly connected to the sleeve 41, and the sleeve 41 is slidably connected to the shaft 43, the frame 33 can be driven to swing back and forth, thereby driving the nozzle 8 to swing back and forth. By rotating the rocker handle 44, the position of the screw sleeve 40 on the screw 39 can be adjusted, thereby adjusting the position of the connecting seat 34 on the limiting rod 36. Therefore, the swing amplitude of the frame 33 can be adjusted, thereby realizing the adjustment of the spraying range of the nozzle 8. By setting an adjustable swing part, the present invention can adjust the spraying range of the nozzle 8 according to the width of the marking to be painted, so that the present invention can meet the spraying of different markings and effectively improve the spraying efficiency.

[0050] Furthermore, a groove is provided on the inner wall of the frame 33, and a movable block is slidably connected in the groove. The movable block is fixedly connected to the connecting seat 34.

[0051] Further reference Figure 2 The reciprocating brushing unit includes brush bristles 31. A connecting plate 20 is fixedly connected to the bottom end of the first hydraulic cylinder 3. A connecting block 26 is provided below the connecting plate 20. Several guide rods 25 slide through the connecting block 26 and are fixedly connected to the connecting plate 20. A slide rail 24 is fixedly connected to the top end of the connecting block 26 and is perpendicular to the guide rods 25. A fourth motor 21 is fixedly connected to the top end of the connecting plate 20. The output shaft of the fourth motor 21 passes through the connecting plate 20. A connecting rod 22 is fixedly connected to the side wall of the output shaft of the fourth motor 21. A limit post 23 is rotatably connected to the bottom end of the connecting rod 22 and slides with the slide rail 24. An air distribution box 29 is fixedly connected to the bottom end of the connecting block 26 and is connected to the blower 2. Several oblique holes 30 are opened through the bottom end of the air distribution box 29. The brush bristles 31 are fixedly connected to the bottom end of the air distribution box 29.

[0052] Furthermore, blower 2 has both cold air and hot air settings. The hot air setting can accelerate the drying of water on the road surface, thus speeding up the project progress, increasing the adhesion between the road surface and the marking paint, and extending the service life.

[0053] The fourth motor 21 drives the connecting rod 22 to rotate, and the connecting rod 22 drives the limiting post 23 to move. The limiting post 23 slides in the groove, while the connecting block 26 is restricted by the guide rod 25. Therefore, the connecting block 26 is driven to reciprocate along the length of the guide rod 25, which in turn drives the brush bristles 31 to sweep the debris on the ground to both sides. The high-pressure airflow generated by the blower 2 is sprayed out through the inclined hole 30, which can more thoroughly clean the dust on the ground and ensure the effect of subsequent spraying.

[0054] Further reference Figure 2 In order to adapt to the undulation of the ground during cleaning, several telescopic rods 27 are provided between the connecting block 26 and the air distribution box 29. The two ends of the telescopic rods 27 are fixedly connected to the connecting block 26 and the air distribution box 29 respectively. A spring 28 is sleeved on the telescopic rods 27, and the two ends of the spring 28 are fixedly connected to the connecting block 26 and the air distribution box 29 respectively.

[0055] Further reference Figure 1 The vertical adjustment unit includes a column 6, a lead screw 5, and a first motor 4. The column 6 is fixed to one side of the vehicle body 1. A sliding groove is provided on the side wall of the column 6. The lead screw 5 is rotatably connected in the sliding groove. The first motor 4 is fixed to the top of the column 6. The output shaft of the first motor 4 is coaxially fixed to the lead screw 5. A slider 7 is threaded on the lead screw 5. The slider 7 slides in the sliding groove. The housing 9 is fixed to the slider 7.

[0056] By controlling the rotation of the first motor 4 to drive the lead screw 5 to rotate, the lead screw 5 can move and thus adjust the distance of the nozzle 8 from the ground. In conjunction with the adjustable swing part, the width of the spraying of the nozzle 8 can be adjusted. At the same time, when spraying is not required, the nozzle 8 can be moved upward to prevent objects from hitting the nozzle 8 and ensure the safety of the nozzle 8.

[0057] Further reference Figure 1 The mixing section includes an electric heating tank 15 and a mixing blade 19. The electric heating tank 15 is fixedly connected to the top of the vehicle body 1. A mixing rod 18 is rotatably connected inside the electric heating tank 15. The mixing blade 19 is fixedly sleeved on the mixing rod 18. A third motor 17 and a feeding hopper 16 are fixedly connected to the top of the electric heating tank 15. The output shaft of the third motor 17 is coaxially fixedly connected to the mixing rod 18. The feeding hopper 16 is connected to the electric heating tank 15. A pump body 13 is fixedly connected to the top of the vehicle body 1. The nozzle 8 is connected to the electric heating tank 15 through the pump body 13.

[0058] The electric heating tank 15 can heat the paint inside, and the stirring of the stirring blades 19 can prevent the paint inside the electric heating tank 15 from solidifying, ensuring the fluidity of the paint inside the electric heating tank 15. Finally, it is pumped to the nozzle 8 through the pump body 13, and then sprayed onto the ground to form markings.

[0059] Further reference Figure 6 The jet section includes an air distribution box 45 and an air distribution block 46. The air distribution box 45 is fixed to the bottom end of the second hydraulic cylinder 12 and is connected to the drying fan 14. The air distribution block 46 is fixed to the inner wall of the bottom end of the air distribution box 45. The air distribution block 46 has a triangular structure and several air distribution channels 47 are opened through the air distribution block 46. Two connected air distribution channels 47 are equally spaced and the air distribution channels 47 pass through the bottom end of the air distribution box 45.

[0060] The hot air generated by the drying fan 14 is introduced into the air distribution box 45, and after being distributed by the air distribution block 46, it is introduced into the air distribution channel 47, and finally blown onto the sprayed marking line to accelerate the drying of the paint. Since the air distribution block 46 has a triangular structure and adjacent air distribution channels 47 are equally spaced, this arrangement can make the hot air after passing through the air distribution channel 47 more uniform, thereby making the drying effect of the paint better.

[0061] Furthermore, the airflow temperature blown out by the drying fan 14 is 25 degrees Celsius, which not only accelerates the solidification of the hot-melt markings on the hot road surface in summer, but also prevents them from cracking due to excessively rapid solidification on the cold road surface in winter.

[0062] A method for using a highway construction marking painting device, comprising the following steps:

[0063] S1. Transfer: Drive vehicle 1 to the road surface where the markings are to be painted, and move vehicle 1 along the road surface;

[0064] S2. Sweeping: Adjust the first hydraulic cylinder 3, and then start the blower 2 and the reciprocating brush unit to sweep the road surface to be marked.

[0065] S3, Spraying: Simultaneously adjust the vertical moving part and the adjustable swing part, and start the adjustable swing part and the stirring part to make the nozzle 8 spray paint to form markings on the road surface;

[0066] S4. Drying: Simultaneously adjust the second hydraulic cylinder 12, and then start the drying fan 14. The jet nozzle blows out hot air to dry the sprayed markings.
