[0029] See also Figure 1-2 A road marking device for road construction includes a traveling flatbed vehicle body 1, a sprayer 2 for spraying road markings on the traveling flatbed vehicle body 1, the sprayer 2 is carried by the traveling flatbed vehicle body 1 and sprays markings while moving, the sprayer 2 has a sprayer nozzle 3 located on one side of the traveling flatbed vehicle body 1 and spraying downwards, and sprays markings, and also includes:

[0030] The cleaning mechanism is arranged at the front end of the traveling flatbed vehicle body 1 and in front of the spray head 3 in the traveling direction to clean the particles on the road surface in front of the traveling flatbed vehicle body 1. After cleaning the particles, the marking line is sprayed to improve the spraying quality and prevent dust, gravel and other particles from affecting the flatness of the marking line;

[0031] A lifting mechanism is arranged at the front end of the traveling flatbed vehicle body 1 and is used to drive the cleaning mechanism to move up and down. Specifically, during the working process, when it is necessary to clean the front position, the cleaning mechanism is driven to descend to the ground for cleaning by the lifting mechanism, and is raised after the work is completed to avoid the cleaning mechanism affecting the normal movement of the device; and

[0038] The telescopic cylinder 12 is arranged on the load-bearing support frame 9 with the telescopic end arranged upward. The telescopic cylinder 12 is connected to the upper end of the lifting longitudinal beam 10 through a connecting piece 13.

[0039] Specifically, the lifting beam 10 is moved by the telescopic cylinder 12, and the longitudinal slide rail 11 supports and guides the lifting beam 10 to move. During the lifting beam 10, the cleaning drum 6 on the gantry 5 is driven to move up and down.

[0040] Further, the purge mechanism includes:

[0041] A high-pressure blower 14, which is arranged on the upper surface of the traveling flatbed vehicle body 1;

[0042] High-pressure nozzles 15, which are two groups symmetrically arranged on both sides of the gantry 5; and

[0043] The high-pressure conduits 16 are two groups of identical structures and are arranged one-to-one between the two groups of high-pressure nozzles 15 . The high-pressure conduits 16 are connected between the high-pressure nozzles 15 and the high-pressure blowers 14 to transport the high-pressure air of the high-pressure blowers 14 to the high-pressure nozzles 15 .

[0044] Furthermore, the two groups of high-pressure nozzles 15 are arranged to spray in the forward and side directions of the cleaning mechanism in the moving direction.

[0045] Specifically, the two groups of high-pressure nozzles 15 deliver high-pressure air through the high-pressure conduit 16 under the action of the high-pressure blower 14, and the high-pressure air is sprayed through the two groups of high-pressure nozzles 15 to blow away the particles. More specifically, the spraying directions of the two groups of high-pressure nozzles 15 are arranged in the front and side directions of the cleaning mechanism in the direction of travel, so that the particles can be blown away in the front and side directions of the cleaning mechanism in the direction of travel.

[0046] In summary, the device utilizes a cleaning mechanism combined with a blowing mechanism to effectively remove dust and stone particles in front of the marking device, thereby avoiding affecting the quality of the marking, eliminating manual operation, saving manpower, and improving work efficiency.
