Description

Technical Field

[0001] This utility model specifically relates to a road marking spraying machine, belonging to the field of road marking spraying technology. Background Technology

[0002] As an important piece of equipment in the construction and maintenance of modern transportation infrastructure, road marking spraying machines uniformly spray hot-melt and cold-spray coatings onto the road surface to form clear and standardized traffic markings. These markings play a crucial role in guiding vehicle traffic, ensuring traffic safety, and improving road traffic efficiency. With the continuous expansion of urban transportation networks and the increasing demand for road maintenance, higher requirements are being placed on the quality and efficiency of road marking spraying.

[0003] However, most road marking sprayers on the market currently lack a cleaning design. Dust and other impurities remaining on the road surface can affect the adhesion of the paint. Dust and other debris can form an isolation layer between the road surface and the paint, making it difficult for the markings to adhere firmly. They are very easy to fall off under the pressure of vehicles. Some debris can also prevent the paint from curing properly, causing bulges and peeling on the surface of the markings. Furthermore, when particulate matter is covered by paint, it can form bumps, which not only affect the flatness of the markings but may also cause damage to the markings when vehicles drive over them.

[0004] To address this problem, this application proposes a road marking spraying machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a road marking spraying machine. Through a designed cleaning mechanism, while the trolley is moving, the machine sequentially blows away dust and debris from the road surface using a dust-blowing nozzle, washes away stains using a rinsing nozzle, and dries the road surface with hot air. After cleaning, the paint nozzle immediately sprays the road markings. This continuous operation mode of blowing, rinsing, drying, and spraying enables rapid integration of cleaning and road marking construction, improves construction efficiency, ensures the quality of road marking spraying, and solves the problems mentioned in the background technology.

[0007] In a preferred embodiment, four sets of casters are installed under the trolley, a fixed plate is installed on one side of the material tank, and a spray pump is installed on the fixed plate. The spray pump is connected to the material tank and the paint nozzle through a connecting pipe. A spray nozzle is opened on one side of the trolley, and the paint nozzle is set inside the spray nozzle. The paint nozzle is fixedly connected to the inner wall of the spray nozzle through a connecting rod.

[0008] In a preferred embodiment, a baffle plate is provided in front of the air box, a snap-fit ​​strip is installed on the upper end of the baffle plate, a set of slots are respectively opened on both sides of the upper surface of the front frame, and the snap-fit ​​strip is embedded in the slots. A rubber strip is glued to the bottom of the baffle plate.

[0009] In a preferred embodiment, the water pipe and the two sides of the air box are fixedly connected to the front frame, a reference rod is installed on one side of the front end of the front frame, and a blower, a water pump and a water tank are also installed on the top of the trolley.

[0010] In a preferred embodiment, the water pump is connected to the water tank via a water pumping pipe and to the water pipe via a transmission pipe; the blower is connected to the air pipe via an air supply pipe; and the hot air blower is connected to the air box via a hot air pipe.

[0011] In a preferred embodiment, a connecting frame is installed above the front frame, and a vertical frame is installed in the middle above the connecting frame. A threaded rod is installed inside the vertical frame, and a set of guide rods is provided on both sides of the threaded rod. The guide rods are fixedly connected to the vertical frame. A lifting crossbar is threaded onto the threaded rod, and the two ends of the lifting crossbar are slidably connected to the two sets of guide rods respectively. A lifting motor is installed above the vertical frame, and the output shaft of the lifting motor is connected to the threaded rod.

[0012] In a preferred embodiment, the linkage plate is located on the side of the upright frame near the air pipe. The linkage plate has a Z-shaped structure.

The output shaft of the rotary motor is connected to the rotating cylinder.

[0013] Beneficial effects:

[0014] 1. By designing a cleaning mechanism, during the movement of the trolley, high-pressure gas generated by a blower is delivered to the dust-blowing nozzles through air pipes to sweep away dust and debris from the road surface. Immediately afterwards, a water pump draws water from the water tank and uses the rinsing nozzles to perform a secondary cleaning of the road surface, removing stains. Finally, hot air generated by a hot air blower is evenly sprayed out through hot air holes to quickly dry the rinsed road surface. After completing the cleaning process, the trolley continues to move forward, and the paint nozzles spray paint to apply road markings. This continuous design of sweeping, rinsing, drying, and spraying achieves a rapid connection between cleaning and road marking construction, effectively improving work efficiency while avoiding the adverse effects of dust, debris, and other factors on the road marking effect.

[0015] 2. By designing a debris removal mechanism, when the cleaning mechanism has difficulty removing stubborn debris from the road surface, the threaded rod rotates under the action of the drive motor, and drives the linkage plate to descend vertically through the linkage rod, so that the wire brush comes into contact with the road surface. At the same time, the rotating motor drives the rotating cylinder to rotate, driving the wire brush to rotate. By utilizing the rigid scraping and flexible adhesion characteristics of the wire brush, the stubborn debris is quickly broken down, achieving efficient cleaning of stubborn debris on the road surface and providing a clean construction base for subsequent marking spraying.

The paint nozzle 16 is installed in the spray nozzle 15 and is fixedly connected to the inner wall of the spray nozzle 15 through a connecting rod.

[0025] Please see Figures 1-4 As shown, a baffle plate 28 is provided in front of the air box 212. A snap-fit ​​strip is installed on the upper end of the baffle plate 28. A set of slots are opened on both sides of the upper surface of the front frame 21, and the snap-fit ​​strip is embedded in the slot. A rubber strip 29 is glued to the bottom of the baffle plate 28. The baffle plate 28 can block the flushing liquid. The rubber strip 29 below it scrapes the liquid as the trolley 13 moves to avoid water accumulation. After wear, it can be easily replaced by gluing. When it is necessary to remove the baffle plate 28, the snap-fit ​​strip can be taken out from the slot to complete the removal of the baffle plate 28.

[0026] Please see Figures 1-2 As shown, the water pipe 210 and the air box 212 are fixedly connected to the front frame 21 on both sides. A reference rod 17 is installed on one side of the front end of the front frame 21. A blower 27, a water pump 25 and a water tank 24 are also installed on the top of the trolley 13. During the movement of the trolley 13, the reference rod 17 can assist the operator in calibrating the direction and position of the marking spray.

[0027] Please see Figures 1-4 As shown, the water pump 25 is connected to the water tank 24 through the water pumping pipe 210, and the water pump 25 is connected to the water pipe 210 through the transmission pipe. The blower 27 is connected to the air pipe 22 through the air supply pipe, and the hot air blower 26 is connected to the air box 212 through the hot air pipe.

[0028] Please see Figures 1-5As shown, a connecting frame 31 is installed above the front frame 21, and a vertical frame 32 is installed in the middle above the connecting frame 31. A threaded rod 36 is installed inside the vertical frame 32. A set of guide rods 35 are provided on both sides of the threaded rod 36, and the guide rods 35 are fixedly connected to the vertical frame 32. A lifting crossbar 37 is threadedly connected to the threaded rod 36, and the two ends of the lifting crossbar 37 are slidably connected to the two sets of guide rods 35 respectively.

When the wire brush 38 rotates, it can quickly remove stubborn debris from the road surface by utilizing the rigid scraping and flexible adhesion characteristics of the wire brush 38.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] When the operator pushes the cart 13, which is equipped with four sets of movable wheels 14, forward, the gas generated by the blower 27 enters the air pipe 22 through the air supply pipe, and is blown away by the inclined dust blowing nozzle 23 to remove dust and debris from the road surface. At the same time, the water pump 25 draws water from the water tank 24 through the water suction pipe 210, and sends it to the water pipe 210 through the transmission pipe. The water is sprayed out by the flushing nozzle 211 to remove stains from the road surface. The baffle plate 28 can block the flushing liquid, and the rubber strip 29 below it scrapes away the liquid as the cart 13 moves to prevent water accumulation. It can be easily replaced by adhesive splicing after wear. Subsequently, the hot air generated by the hot air blower 26 enters the air box 212 through the hot air pipe, and is evenly sprayed out through the hot air hole 213 at the bottom of the air box 212 to quickly dry the road surface.

[0032] If stubborn debris is encountered, the lifting motor 33 is started. The lifting motor 33 drives the threaded rod 36 to rotate, causing the lifting crossbar 37 to descend along the guide rod 35. This causes the linkage plate 34 to descend, bringing the wire brush 38 into contact with the road surface. The rotating motor 39 drives the rotating cylinder 310 to rotate, thereby causing the wire brush 38 to rotate and remove the debris. After cleaning is completed, the trolley 13 continues to move forward. The spray pump 12 transports the paint in the material tank 11 to the paint nozzle 16 through the connecting pipe, and sprays the paint to achieve the marking spraying.
