[0032] Reference Appendix Figure 1-5 This embodiment provides a road marking device, which includes: a vehicle body 1, a dust removal mechanism 2, a marking mechanism 3, a limiting mechanism 4, and a paint curing mechanism 55. The dust removal mechanism 2, the marking mechanism 3, the limiting mechanism 4, and the paint curing mechanism 55 are mounted on the vehicle body 1 and can move with the vehicle body 1 to perform tasks such as dust removal and marking. The dust removal mechanism 2 and the paint curing mechanism 55 are located on both sides of the marking mechanism 3, respectively, for cleaning the road surface before the marking mechanism 3 sprays and for curing the road surface paint after the marking mechanism 3 sprays. The limiting mechanism 4 is located between the dust removal mechanism 2 and the marking mechanism 3, and at least partially surrounds the spraying area of ​​the marking mechanism 3 to prevent paint from splashing during the spraying of the marking mechanism 3.

[0033] The vehicle body 1 includes a base 101, casters 102, a push handle 103, a power supply 104, and control keys 105. The casters 102 are located at the bottom of the base 101, and the push handle 103 is located at the top of the base 101 at an angle for a person to hold and push the vehicle body 1. The power supply 104 is located on the base 101 and can be a storage battery or a new energy battery (such as a solar cell) to power the dust removal mechanism 2, the marking mechanism 3, and the paint curing mechanism 55. The control keys 105 are located on the push handle 103 and are connected to the power supply 104, the dust removal mechanism 2, the marking mechanism 3, and the paint curing mechanism 55 to regulate their operating status.

[0034] The dust removal mechanism 2 includes an air filter box 201, an air pump 204, a first air nozzle 205, a second air nozzle 206, and air pipes. Depending on the connected components, this embodiment divides the air pipes into a first air pipe 207, a second air pipe 208, a third air pipe 209, and a fourth air pipe 210. The air filter box 201 is fixedly mounted on the top of the base 101 and contains an air filter screen 211. The air filter screen 211 divides the inner cavity of the air filter box 201 into a first inner cavity 2. 02 and the second inner cavity 203, the first inner cavity 202 is located above the second inner cavity 203; the air pump 204 is fixedly mounted on the top of the air filter box 201, its input end is connected to the first inner cavity 202, and its output end is connected to the first air nozzle 205 through the first air pipe 207 and the second air pipe 208, for delivering the gas in the first inner cavity 202 to the first air nozzle 205; the second air nozzle 206 is connected to the second inner cavity 203 through the third air pipe 209 and the fourth air pipe 210.

[0035] When in use, the air pump 204 is started, and the air pump 204 delivers the gas in the first inner cavity 202 to the first air nozzle 205. The first air nozzle 205 sprays the gas toward the ground, blowing up the dust on the ground. Since the air pump 204 sucks up the gas in the first inner cavity 202, the air filter box 201 is in a negative pressure state. Since the second inner cavity 203 is connected to the first inner cavity 202, and the second air nozzle 206 is connected to the second inner cavity 203 and the atmosphere, the negative pressure state will generate suction at the second air nozzle 206. Dust falling back to the ground from the air, especially dust that returns to the area to be marked, will be sucked into the second inner cavity 203 by the second air nozzle 206, thereby ensuring the cleanliness of the area to be marked and improving the subsequent marking quality. The dust and air drawn into the second inner cavity 203 are filtered by the air filter 211. The dust remains in the second inner cavity 203, while the air enters the first inner cavity 202. This ensures the cleanliness of the gas sprayed from the first air nozzle 205 and guarantees its effectiveness in cleaning the ground.

[0036] The input end of the first air pipe 207 is connected to the air pump 204, and the output end is vertical. The output end of the third air pipe 209 is connected to the air filter box 201, and the input end is vertical. The second air pipe 208 and the fourth air pipe 210 are respectively arranged horizontally and connected to the output end of the first air pipe 207 and the input end of the third air pipe 209, respectively, so as to install multiple horizontally parallel first air nozzles 205 or multiple horizontally parallel second air nozzles 206, to ensure that the width of the cleaning area of ​​the cleaning mechanism 2 is compliant and reasonable, and to improve the cleaning efficiency.

[0037] In addition, a connecting short beam 212 can be constructed between the second air pipe 208 and the fourth air pipe 210 to improve stability.

[0038] To improve cleaning efficiency and quality, this embodiment optimizes the structure of the first air nozzle 205 and the second air nozzle 206 as follows: the inner diameter of the first air nozzle 205 gradually decreases along the direction away from the air pump 204; the inner diameter of the second air nozzle 206 gradually decreases along the direction close to the second inner cavity 203.

[0039] To ensure efficient and high-quality dust removal, the inner wall of the air filter box 201 and the air filter 211 need to be cleaned or inspected regularly. Therefore, in this embodiment, a side door panel 213 is hinged to one side of the air filter box 201. The non-hinged end of the side door panel 213 is snap-fitted to the air filter box 201, and a sealing gasket is provided on the contact surface between the side door panel 213 and the air filter box 201. Furthermore, the air filter 211 is detachably connected to the inner wall of the air filter box 201, for example, by horizontally sliding the air filter 211 to the inner wall of the air filter box 201 (see attached diagram). Figure 4 ).

[0040] The marking mechanism 3 includes a paint bucket 301, a paint pump 302, a quick connector 303, a paint pipe 304, a stirring motor 305, and a stirring blade 306. The paint bucket 301 is fixedly mounted on the top of the base 101, and a filling port 307 is provided on the top of the paint bucket 301. The stirring motor 305 is located on the top of the paint bucket 301, and the stirring blade 306 is located inside the paint bucket 301 and connected to the stirring motor 305 via a vertical shaft. When the stirring motor 305 is started, the stirring blade 306 can rotate around its output shaft to stir the paint filled by the filling port 307. Pump 302, paint pipe 304, and quick connector 303 are located on the lower part of paint bucket 301. Quick connector 303 is connected to paint bucket 301 through paint pipe 304 and paint pump 302. Paint pump 302 can transport paint in paint bucket 301 to quick connector 303 through paint pipe 304. The output end of quick connector 303 is connected to paint nozzle 308. Different models of paint nozzle 308 can be replaced as needed. The output end of paint nozzle 308 is bent towards limiting mechanism 4, so that limiting mechanism 4 can limit the paint sprayed from paint nozzle 308 to avoid splashing.

[0041] The limiting mechanism 4 includes a first mounting frame 401, a paint baffle 402, a bidirectional lead screw 403, a slider 404, a drive wheel 405, and a first guide rod 406. The first mounting frame 401 is plate-shaped, with one end connected to the base 101 and the other end suspended. A limiting groove 407 is provided on the first mounting frame 401. The bidirectional lead screw 403 extends in a direction perpendicular to the road marking and is rotatably connected to the limiting groove 407. The end of the bidirectional lead screw 403 extending out of the limiting groove 407 is connected to the drive wheel 405. The slider 404, paint baffle 402, and drive wheel 406 are also included. Two sets of baffles 402 and first guide rods 406 are provided respectively. Slider 404 slides against the inner wall of the limiting groove 407. The two sets of sliders 404 are respectively threaded onto the threads in opposite directions in the bidirectional lead screw 403. The two sets of paint baffles 402 are located below the first mounting bracket 401 and are respectively connected to different sliders 404, restricting the output end of the paint nozzle 308 between the two sets of paint baffles 402. The first guide rod 406 extends along the direction of the road marking and one end is connected to the side of the paint baffle 402 near the dust removal component.

[0042] During use, replace the paint nozzle 308 with the appropriate model according to the marking width; rotate the drive wheel 405 to drive the double-acting screw 403 to rotate. At this time, the slider 404 will move along the axial direction of the double-acting screw 403. Since the threads are opposite, the two sliders 404 will move towards or away from each other, causing the distance between the two sets of paint baffles 402 to change. Adjust it to match the marking width and then stop rotating the drive wheel 405. During the marking operation, the first guide rod 406 can be compared with the road positioning mark before marking. If the first guide rod 406 deviates too much from the road positioning mark, it indicates that the marking is crooked, reminding the worker to adjust the travel direction of the vehicle 1.

[0043] In addition, graduations can be set on the paint baffle 402 to provide workers with guidance when adjusting the distance between the two sets of paint baffles 402. A rubber sheet can also be set on the bottom surface of the paint baffle 402 to prevent the paint baffle 402 from being worn out quickly due to friction with the ground.

[0044] The coating curing mechanism 55 includes a second mounting frame 501, a lifting screw 502, and a heating plate 503. The second mounting frame 501 is plate-shaped, with one end connected to the base 101 and the other end suspended. The lifting screw 502 is vertically arranged and passes through and is threaded to the second mounting frame 501. The heating plate 503 is located below the second mounting frame 501, and its top surface is rotatably connected to the bottom end of the lifting screw 502. When the lifting screw 502 rotates, the heating plate 503 can be raised or lowered. The heating plate 503 has a mounting groove 504 with an opening facing away from the second mounting frame 501. An electric heating tube 505 is arranged in the mounting groove 504, and a grid 506 that can be detachably connected to the mounting groove 504 is arranged at the bottom of the electric heating tube 505.

[0045] When it is necessary to cure the paint sprayed by the marking mechanism 3, rotate the lifting screw 502 to bring the heating plate 503 close to the ground to a suitable position, and start the electric heating tube 505 to heat the paint on the ground, thereby accelerating the drying and curing speed of the paint.

[0046] To ensure the smooth lifting and lowering of the heating plate 503, this embodiment also includes a second guide rod 507 slidably passing through the second mounting bracket 501. The second guide rod 507 extends in the same direction as the lifting screw 502, and its bottom end is connected to the heating plate 503. When the lifting screw 502 is rotated to lift and lower the heating plate 503, the second guide rod 507 can also be lifted and lowered accordingly, working together to ensure the smooth movement of the heating plate 503.

[0047] Compared with the prior art, the beneficial effects of this utility model include at least the following: it provides a road marking device that integrates dust removal, line marking, and paint curing promotion functions. The entire road marking process can be completed by a single person operating the control key 105 on the vehicle body 1, which can reduce labor consumption and lower operating costs. In addition, through the structural optimization design of the dust removal mechanism 2, the dust that falls back onto the marking area is cleaned a second time, improving the dust removal quality of the marking area. By constructing a limiting mechanism 4 between the dust removal mechanism 2 and the marking mechanism 3, paint splashing can be avoided, and paint spots on both sides of the marking can be avoided, thus improving the overall quality of paint marking.

[0048] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
