[0002] Road engineering is the whole process of planning, designing, constructing, maintaining and managing roads and the engineering entities involved. During the road construction process, road traffic markings are often set on the road surface to control and guide traffic. During construction, the road surface is first blown clean of dirt and other debris, and then the marking machine is used in conjunction with manual movement to mark the road surface.

[0003] At present, when road marking equipment is used, it is mostly marked by high-pressure spraying, that is, the paint is pumped into the nozzle through a material pump, and then the paint is sprayed out from the nozzle at high pressure to quickly mark the line. Since the spray range of the nozzle is fixed, the width of the line drawn by it is fixed. When it is necessary to set multiple lines with large width differences on the road surface, it is often necessary to replace nozzles of different sizes or use a combination of multiple nozzles for spraying. The operation is inconvenient and it is difficult to accurately adjust the line width. There are many inconveniences in use, which greatly affects the use effect of the equipment.

[0074] S5: Start the pump 6 to pump the paint in the storage tank 5 into the feed pipe 7, and then the paint enters the spray head 8 and is sprayed out through the spray head 8. As the spray head 8 moves, the marking operation can be performed on the ground;

[0075] S6: When different line widths need to be marked, the staff can first control the distance adjustment component, by rotating the fixed handle 44 on the distance adjustment component, so that the fixed handle 44 drives the threaded rod 43 to rotate, and then the threaded rod 43 drives the slider 52 to move, so that the slider 52 drives the positioning column 33 to slide along the slide groove 42, so as to change the position of the positioning column 33 on the movable column 32, so as to adjust the distance between the positioning column 33 and the first fixed rod 30;

[0076] S7: After the spacing is adjusted, the third motor 28 can be started, so that the third motor 28 drives the driving gear 29 to rotate, and then the driving gear 29 drives the driven gear 31. The diameter of the driven gear 31 is smaller than the driving gear 29, so that the first fixed rod 30 can quickly drive the movable column 32 to rotate, and then the movable column 32 drives the positioning column 33 to make a circular motion. As the positioning column 33 slides in the guide groove 36, the guide plate 35 can drive the second fixed rod 34 to rotate. At the same time, the second fixed rod 34 drives the first sector toothed disc 37 to rotate, so that the first sector toothed disc 37 drives the second sector toothed disc 39 to rotate, and then the second sector toothed disc 39 drives the mounting seat 40 to rotate through the third fixed rod 38, so that the mounting seat 40 can drive the spray head 8 to swing back and forth quickly through the mounting block 41. As the spray head 8 swings rapidly and slowly, the marking width can be effectively adjusted, and the width of the marking can be adjusted by adjusting the spacing between the positioning column 33 and the first fixed rod 30, so that the marking operation can be performed according to different needs.
