Description

Technical Field

[0001] This invention relates to the field of road maintenance technology, and in particular to a road marking spraying vehicle. Background Technology

[0002] Road marking painting is a routine part of road maintenance. Road markings are lines, arrows, words, etc., painted on the road surface to control and guide traffic. Due to long-term exposure to sun, rain, wind, snow, ice, and the impact and wear of vehicles, they will gradually become blurred and illegible over time, thus creating safety hazards.

[0003] Paint sprayers are commonly used tools for road marking spraying, mainly suitable for hot-melt marking. They have advantages such as high efficiency and labor saving. In order to make the sprayed markings sharp and angular, they are generally used with a mat. The mat is laid on the travel route of the paint sprayer to limit the spraying area. This method can make the sprayed markings sharp and angular, but it also leaves a lot of paint residue on the mat, which not only causes waste, but also affects the flatness of the mat when used later. However, the current paint sprayers do not have the function of cleaning the mat. It is necessary to manually remove it to one side and clean it, and then collect the paint back onto the paint sprayer. This back and forth is extremely inconvenient and affects work efficiency. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes a road marking spraying vehicle.

[0005] A road marking spraying vehicle includes: a spraying vehicle body, a scraper table, a scraper blade, and a transmission mechanism;

[0025] The scraper platform 2 is fixed on the trolley 100 and is on the same side as the material tank 200 and the gas tank 300. The scraper 3 is horizontally installed on the scraper platform 2 and is slidably connected to the scraper platform 2. The transmission mechanism 4 is installed on the trolley 100 to transmit the power of the traveling wheel 500 to the scraper 3 and push the scraper 3 to slide on the scraper platform 2. More specifically, the axle 600 is driven to connect to the scraper 3 through the transmission mechanism 4.

[0026] refer to Figure 2 and Figure 3The transmission mechanism 4 includes: a first rotating shaft 41, a second rotating shaft 42, a first bevel gear 43, a second bevel gear 44, a transmission belt 45, and a cam 46. The trolley 100 is provided with a bracket 11 and has a vertical through hole 12. The first rotating shaft 41 and the second rotating shaft 42 are vertically arranged on the bracket 11 and rotatably connected to the bracket 11. The transmission belt 45 connects the first rotating shaft 41 and the second rotating shaft 42. One end of the first rotating shaft 41 passes through the through hole 12 and is equipped with the first bevel gear 43. The second bevel gear 44 is installed on the axle 600 and meshes with the first bevel gear 43. The cam 46 is fixed to the end of the second rotating shaft 42 and abuts against one side of the scraper 3.

[0027] Another implementation of the transmission mechanism 4 is described in reference. Figure 4 and Figure 5 The first rotating shaft 41 is installed at the bottom of the trolley 100 and parallel to the axle 600. The transmission belt 45 connects the first rotating shaft 41 and the axle 600. The trolley 100 is provided with a bracket 11 and has a vertical through hole 12. The second rotating shaft 42 is rotatably installed on the bracket 11 in the vertical direction, and one end of it passes through the through hole 12 and is equipped with a first bevel gear 43. The second bevel gear 44 is installed on the first rotating shaft 41 and meshes with the first bevel gear 43. The cam 46 is fixed to the other end of the second rotating shaft 42 and abuts against one side of the scraper 3.

[0028] refer to Figure 6 The scraper table 2 includes a base 21. The top surface of the base 21 is provided with a groove 22. One side of the groove 22 penetrates the base 21 to form an opening on one side of the base 21. The scraper 3 is set at the opening so as to contact the transmission mechanism 4. A portion of the bottom surface of the groove 22 is recessed downward to form a placement area 25 to prevent the pad that needs to be cleaned. The base 21 is also provided with a vertically extending drop trough 23. The drop trough 23 is distributed at both ends of the groove 22 opposite to the opening. Under the push of the transmission mechanism 4, the scraper 3 can scrape off the paint on the pad and push it into the drop trough 23.

[0029] To facilitate the collection of the cleaned-off paint, the bottom of the base 21 is provided with a cavity that connects to the discharge chute 23. The cavity contains a receiving box 24 for receiving the cleaned-off paint, and the receiving box 24 can be pulled out.

The guide rod 5 is horizontally arranged and a spring 6 is sleeved on the guide rod 5. The spring 6 and the cam 46 are distributed on both sides of the blade holder 31. When the cam 46 pushes the blade holder 31, the spring 6 can be compressed. The main function of the spring 6 is to drive the blade holder 31 to reset when the force of the cam 46 is removed, so that the scraper 3 can reciprocate. The blade 32 is fixed on the blade holder 31 and there is a gap between its cutting edge and the surface of the scraper table 2.

[0031] More specifically, the guide rods 5 are distributed on both sides of the groove 22, and there is a gap between the cutting edge of the blade 32 and the bottom surface of the groove 22.

[0032] In this embodiment, the coating plate can be placed in the placement area 25. When the coating cart is moved, the axle 600 rotates and drives the cam 46 to rotate through the transmission belt 45 and the meshing of the bevel gear. During the rotation of the cam 46, the scraper 3 can be periodically pushed to slide on the scraping table 2, thereby scraping off the coating on the plate and pushing it into the drop trough 23. Finally, it enters the receiving box 24 for centralized collection. There is no need for manual cleaning and return, thus saving manpower and reducing workload.
