[0012] Compared with the prior art, the present invention has outstanding substantial features and significant progress. Specifically, when the present invention is working, first pour the two-component paint into the paint tank, start the power system, and make the marking vehicle move forward at a constant speed. Under the guidance of the direction of the guide device, the staff sits on the operating platform seat and controls the paint pressure delivery component and the glass bead pressure delivery component respectively through the control panel. First, the height of the marking hopper is adjusted by the third cylinder. Specifically, the piston rod of the third cylinder is extended and retracted to drive the rear hopper fixing frame to move up and down through the second cylinder. The rear hopper fixing frame drives the marking hopper to flip up and down around the hinge support through the front hopper fixing frame until the marking hopper is adjusted to a suitable height, so that the lower side edges of the two oscillating hopper knife seats are in contact with the road surface, and then the two-component room temperature paint is compressed by compressed air. After being pressurized, it is sent into the paint pump pipe through the paint diaphragm valve. The two-component room temperature paint is then fully mixed with the curing agent through the curing agent mixing pipe and then enters the marking hopper. According to the line requirements, the material door opening and closing assembly and the cover plate opening and closing assembly are controlled to draw a flat line or a rib oscillation line; when it is necessary to draw a flat line, the piston rod of the first cylinder is controlled to retract forward, and the second cylinder maintains the initial state. The lower side of the cover plate, the bottom surface of each baffle block and the bottom surface of the rear section of the paint scraper plate are all flush. The piston rod of the first cylinder drives the material door to slide forward a certain distance (3mm) through the first arc-shaped ear plate, and a certain width of gap is opened between the rear section of the paint scraper plate and the rear side plate of the marking hopper. The two-component room temperature paint slides along the paint guide block through the first scraping port, and then along the paint The scraper plate slides down and is squeezed and scraped onto the road surface through the gap between the paint scraper plate and the rear side plate of the marking hopper to draw a flat line; when the oscillation line is to be drawn, the first cylinder is controlled to maintain the initial state, and the rear side edge of the rear long strip of the paint scraper plate is pressed and contacted with the front side of each baffle block. The second cylinder is controlled to maintain the initial state first, and the lower side edge of the cover plate, the bottom surface of each baffle block and the bottom surface of the rear long strip of the paint scraper plate are all flush, then the two-component normal temperature paint slides along the paint guide block through the first scraping port, and then slides down along the paint scraper plate and is squeezed out through each paint outlet. The two-component normal temperature paint is then applied downwards onto the road surface through the gap between the cover plate and each baffle block, and the cover plate then scrapes the two-component normal temperature paint flat to draw a bottom flat line. After a certain distance, the piston rod of the second cylinder is controlled to retract upward, and the piston rod of the second cylinder drives the cover plate to move upward to a certain height (9mm) through the second arc-shaped ear plate, so that each baffle block is exposed, and the cover plate no longer blocks and covers each paint outlet. Then a large amount of two-component room temperature paint is directly squeezed and scraped onto the road surface through each paint outlet to form a number of rib oscillation protrusions. After that, the piston rod of the second cylinder is controlled to extend downward to the initial state, so that the cover plate moves down to the initial state, and then a bottom horizontal line of a certain distance is drawn. Then the piston rod of the second cylinder is controlled to retract upward, and the cover plate moves upward to a certain height, and then a number of rib oscillation protrusions are formed. Repeat the above actions to make the second cylinder drive the cover plate to move up and down intermittently, and then the rib oscillation line can be drawn.Among them, when drawing markings such as horizontal lines and rib oscillation lines, glass beads are evenly sprayed on the marking surface through the glass bead spray gun assembly to increase the reflective effect of the marking.

[0013] The two oscillating hopper knife seats can limit the width of the marking line when marking, prevent the paint from overflowing to both sides, and make the marking line neat on both sides. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the piston rod of the third cylinder 25 is hinged to the upper end of the cylinder body of the second cylinder 20 and its hinge axis is horizontally arranged in the left and right directions.

[0026] When the present invention is working, first pour the two-component paint into the paint tank 39, start the power system 38, and make the marking vehicle move forward at a constant speed. Under the guidance of the direction of the guide device 37, the staff sits on the seat 45 of the operating platform 41 and respectively controls the paint pressure delivery component and the glass bead pressure delivery component through the control console 46. First, the height of the marking hopper 2 is adjusted by the third cylinder 25. Specifically, the piston rod of the third cylinder 25 is extended and retracted to drive the rear hopper fixing frame 9 to move up and down through the second cylinder 20. The rear hopper fixing frame 9 drives the marking hopper 2 to turn up and down around the hinge support 11 through the front hopper fixing frame 8 until the marking hopper 2 is adjusted to a suitable height, so that the lower side edges of the two oscillating hopper knife seats 13 are in contact with the road surface. Then, the two-component room temperature paint is pressurized by compressed air and sent into the paint pump inlet pipe 6 through the paint diaphragm valve 4. The two-component room temperature paint is then mixed with the curing agent through the curing agent mixing pipe 3. After the chemical is fully mixed, it enters the marking hopper 2. The opening and closing assembly of the material gate 15 and the opening and closing assembly of the cover plate 21 are controlled according to the line requirements to draw a flat line or a rib oscillation line. When it is necessary to draw a flat line, the piston rod of the first cylinder 14 is controlled to retract forward, and the second cylinder 20 maintains the initial state. The lower side of the cover plate 21, the bottom surface of each blocking block 24 and the bottom surface of the rear section of the paint scraping plate 19 are all flush. The piston rod of the first cylinder 14 drives the material gate 15 to slide forward a certain distance (3mm) through the first arc-shaped ear plate 18, opening a certain width of gap between the rear section of the paint scraping plate 19 and the rear side plate of the marking hopper 2. The two-component room temperature paint slides along the paint guide block 12 through the first scraping opening, then slides backward along the paint scraping plate 19 and is squeezed and scraped onto the road surface through the gap between the paint scraping plate 19 and the rear side plate of the marking hopper 2 to draw a flat line.When the oscillation line is to be drawn, the first cylinder 14 is controlled to maintain its initial state, and the rear side of the rear long strip of the paint scraper 19 is pressed and contacted with the front side of each blocking block 24. The second cylinder 20 is controlled to maintain its initial state first, and the lower side of the cover plate 21, the bottom surface of each blocking block 24 and the bottom surface of the rear long strip of the paint scraper 19 are all flush. Then the two-component room temperature paint slides along the paint guide block 12 through the first scraping port, and then slides backward along the paint scraper 19 and is squeezed out through each paint outlet. The two-component room temperature paint is then applied downward on the road surface through the gap between the cover plate 21 and each blocking block 24. The cover plate 21 then scrapes the two-component room temperature paint to draw a bottom line. After the bottom line draws a certain distance, the piston rod of the second cylinder 20 is controlled to retract upward. The piston rod of the second cylinder 20 moves upwards to a certain height (9 mm) through the second arc-shaped ear plate 23, exposing the baffles 24. The cover plate 21 no longer blocks and covers the paint outlets, allowing a large amount of two-component ambient temperature paint to be directly squeezed and applied to the road surface through the paint outlets, forming a number of rib-shaped oscillating protrusions. The piston rod of the second cylinder 20 is then controlled to extend downwards to its initial position, causing the cover plate 21 to move downwards to its initial position, thereby drawing a bottom horizontal line for a certain distance. The piston rod of the second cylinder 20 is then controlled to retract upwards, causing the cover plate 21 to move upwards to a certain height, thereby forming a number of rib-shaped oscillating protrusions. This action is repeated, causing the second cylinder 20 to drive the cover plate 21 to move up and down intermittently, thereby drawing a rib-shaped oscillating line.

[0027] Among them, when drawing marking lines such as horizontal lines and rib oscillation lines, the glass beads are evenly sprayed on the surface of the marking line through the glass bead spray gun assembly 5 to increase the reflective effect of the marking line.

[0028] The two oscillating hopper knife seats 13 can limit the width of the marking line when marking, prevent the paint from overflowing to both sides, and make both sides of the marking line neat.
