A storage box 8 is welded to the bottom side of the top plate of the limit frame 3. A cavity is provided inside the storage box 8. A nozzle 9 is installed on the bottom plate of the storage box 8. The nozzle 9 is connected to the cavity inside the storage box 8. An air guide pipe 10 is connected to the side wall of the storage box 8. A material guide pipe 11 is fixedly connected to the top plate of the storage box 8. The material guide pipe 11 passes through the top plate of the limit frame 3. A paint bucket 12 is installed on the base 1. A feed pipe 13 is installed on the paint bucket 12. The paint bucket 12 is connected to the material guide pipe 11. A fixing seat 14 is installed on the base 1, and an air pump 15 is installed on the base 1 through the fixing seat 14. An air inlet pipe 16 is installed at one end of the air pump 15, and an air outlet pipe 17 is installed at the other end of the air pump 15. The air outlet pipe 17 is fixedly connected to the other end of the air guide pipe 10. Four sets of pulleys 18 are installed on the bottom side of the base 1. The four sets of pulleys 18 are arranged in a rectangular array structure. A handle 19 is installed on the base 1. When working, the existing spraying mechanism cannot adjust the spraying width in accordance with the marking width during the process of spraying on the road. During the spraying process, multiple overlapping spraying is performed, resulting in low spraying efficiency. By pushing the handle 19, the pulley 18 rolls on the ground, driving the spraying mechanism to move, and at the same time the air pump 15 is operated. After the air enters the air pump 15 from the air inlet pipe 16, it is compressed by the air pump 15. Then, the compressed air is introduced into the storage box 8 and the nozzle 9 from the air guide pipe 10.

[0019] Since a limiting frame 3 and a movable plate 7 are arranged on the periphery of the nozzle 9, the three side plates of the limiting frame 3 and the movable plate 7 form a square limiting groove 20. The range of paint sprayed by the nozzle 9 is a square structure, that is, the range area of the limiting groove 20. By turning the knob 21, the screw rod 5 is driven to rotate, and the screw rod 5 drives the slider 6 thereon to move horizontally, and the slider 6 drives the movable plate 7 to move horizontally, thereby realizing the position adjustment of the movable plate 7. By changing the position of the movable plate 7, the width of the paint spraying range is adjusted. This structure can adjust the spraying width, avoids overlapping spraying due to insufficient spraying width, and is conducive to improving the spraying efficiency.

[0020] Working principle: the existing spraying mechanism cannot adjust the spraying width according to the width of the marking line during the process of spraying on the road, so that multiple overlapping sprays are performed during the spraying process, resulting in low spraying efficiency. By pushing the handle 19 and the pulley 18 rolling on the ground, the spraying mechanism is driven to move, and the air pump 15 is operated at the same time. After the air enters the air pump 15 from the air inlet pipe 16, it is compressed by the air pump 15, and then the compressed air is introduced into the storage box 8 and the nozzle 9 from the air guide pipe 10. The airflow of the compressed air forms a partial vacuum at the front end of the nozzle 9, which sucks the paint in the paint bucket 12 and sprays it out in atomized form, and the paint is sprayed onto the ground, effectively The spray marking of the highway is realized; since the limiting frame 3 and the movable plate 7 are arranged on the periphery of the nozzle 9, the three side plates of the limiting frame 3 and the movable plate 7 constitute a square limiting groove 20, and the range of the paint sprayed by the nozzle 9 is a square structure, that is, the range area of the limiting groove 20. By turning the knob 21, the screw rod 5 is driven to rotate, and the screw rod 5 drives the slider 6 thereon to move horizontally, and the slider 6 drives the movable plate 7 to move horizontally, thereby realizing the position adjustment of the movable plate 7. By changing the position of the movable plate 7, the width of the paint spraying range is adjusted. This structure can adjust the spraying width, avoids overlapping spraying due to insufficient spraying width, and is conducive to improving the spraying efficiency.
