At the same time, the residual heat of the heating device on the marking vehicle heats the compressed air generated by the air compressor on the marking vehicle. The heated compressed air is blown to the swept road surface through the dust blowing heating device to completely clean the road dust and heat the road surface at the same time, so as to improve the adhesion of the marking paint. In addition, when the road surface is wet and it rains lightly, the hot air blown out by the dust blowing heating device can quickly dry the road surface without affecting the marking construction. The marking module sprays the marking paint on the road surface along the marking line position, and the glass bead spray gun sprays glass beads on the marking line, so the marking line quality is high.

[0014] The invention has a compact overall structure and a high degree of integration. The hopper marking device can be adjusted left and right according to the position of the marking line, and the road surface can be cleaned, dust blown and heated to improve the marking quality.

When it is working, the marking vehicle is driven to the road to be marked, and the piston rods of the first hydraulic cylinder 6 and the second hydraulic cylinder 7 are adjusted to extend according to the marking line position, so that the second guide rail frame 3 is extended to the left from the left end of the first guide rail frame 2, and the fourth guide rail frame 5 is extended to the right from the third guide rail frame 4.

The sweeping roller motor 27 works to drive the sweeping roller shaft 25 to rotate, and then the sweeping roller shaft 25 drives the sweeping roller brush 26 to rotate, and the sweeping roller brush 26 cleans the road surface. At the same time, the residual heat of the heating device on the marking vehicle heats the compressed air generated by the air compressor on the marking vehicle. The heated compressed air is blown to the cleaned road surface through the dust blowing heating device to completely blow away the dust on the road surface. At the same time, the road surface is heated to improve the adhesion of the marking paint. In addition, when the road surface is wet and it rains lightly, the hot air blown out by the dust blowing heating device can quickly dry the road surface without affecting the marking construction. The marking module 29 sprays the marking paint on the road surface along the marking line position, and the glass bead spray gun 31 sprays glass beads on the marking line, so that the marking line quality is high.
