[0032] As Figure 1 and Figure 3 shown, an embodiment of the present utility model provides an airport pavement concrete asphalt spraying tool, which includes a vehicle body 1. Universal wheels 10 are assembled at the four corners of the bottom of the vehicle body 1. Guide rails 5 are vertically fixed at the side edges of the top of the vehicle body 1. A spray gun 6 is assembled on the guide rails 5. An electric push rod 19 for pushing the spray gun 6 to lift is installed at the top end of the guide rails 5. An air compressor 2 for supplying air to the spray gun 6 is assembled at one end of the top of the vehicle body 1. A storage bucket 4 for supplying materials to the spray gun 6 is assembled at the other end of the top of the vehicle body 1. A vertical rod 7 is assembled at one end of the vehicle body 1 facing the storage bucket 4. A junction box 9 is also provided on the vehicle body 1. The electric push rod 19 and the air compressor 2 are connected to an external power source by using the junction box 9. Then, asphalt paint is loaded into the storage bucket 4. The asphalt paint is conveyed into the spray gun 6 under the action of gravity. Then, by using the high-pressure gas conveyed by the air compressor 2, it is sprayed out by the spray gun 6, so that the side of the concrete can be sprayed with asphalt, achieving the purpose of brushing the asphalt isolation layer for the longitudinal keyway joint and the transverse construction joint of the pavement. Moreover, the vehicle body 1 can be pushed to move continuously along the side of the concrete pavement for spraying through the vertical rod 7. The operation is simple, the work efficiency is high, and the labor intensity is reduced.
[0033] As Figure 1 and Figure 2 shown, the top end of the vertical rod 7 bends away from the vehicle body 1 and is horizontally equipped with a handle 8, which is convenient for construction workers to push the vehicle body 1 to move. A feeding port 15 is arranged at the top end of the storage barrel 4, and a top cover 16 is covered on the feeding port 15, which is convenient for putting asphalt paint into the storage barrel 4. A carrier 3 is arranged on the top of the vehicle body 1, and the storage barrel 4 is assembled on the top of the carrier 3. The carrier 3 includes brackets 11 fixed on both sides of the top of the vehicle body 1 and a carrier plate 12 fixed between the top ends of a pair of brackets 11. The carrier plate 12 is higher than the top end of the guide rail 5, and the storage barrel 4 is assembled on the carrier plate 12. Through this structural design, the asphalt paint in the storage barrel 4 can be replenished into the spraying gun 6 under the action of gravity. A triangular reinforcing plate 13 is fixed between the side wall of the bracket 11 and the lower surface of the carrier plate 12, and a connecting strip plate 14 bolted to the vehicle body 1 is arranged at the bottom of the bracket 11.
[0034] As Figures 1 to 4 shown, a rail groove 17 is vertically opened on the guide rail 5, and a slider 18 is slidably embedded in the rail groove 17. The spraying gun 6 is assembled on the slider 18. The telescopic end of the electric push rod 19 extends into the rail groove 17 and is connected to the slider 18. By starting the electric push rod 19 to push the slider 18 to slide along the rail groove 17, the height of the spraying gun 6 can be adjusted, which can adapt to the spraying construction on the side of concrete with different thicknesses and improve the spraying effect during the asphalt coating process of large-area airfield roads. A guide groove 21 is vertically opened on the side wall of the guide rail 5, and the guide groove 21 communicates with the rail groove 17. A convex block 22 embedded in the guide groove 21 is arranged on the side wall of the slider 18, which is used to guide the lifting of the rail groove 17. An air intake connecting pipe 24 is arranged at the rear end of the spraying gun 6, and the air intake connecting pipe 24 is connected to the air compressor 2 through an air delivery pipe. A flow regulating valve 25 is arranged at the position of the spraying gun 6 close to the air intake connecting pipe 24.

The front end of the spraying gun 6 is assembled with a nozzle 20, and the nozzle 20 is set as a flat fan-shaped structure. The nozzle 20 has multiple fan-shaped distribution spraying channels 23 inside. The fan-shaped nozzle 20 can make the sprayed asphalt in a uniform fan shape and can be better attached to the side of the concrete.
[0035] The working principle of the technical solution provided by the present utility model is as follows:
[0036] In use, the coating joint 26 is connected to the discharge joint 27 through a material conveying pipe, and the air intake connecting pipe 24 is connected to the air compressor 2 through an air conveying pipe. The electric push rod 19 and the air compressor 2 are connected to an external power supply by using the junction box 9. Then, asphalt coating is loaded into the storage bucket 4. The asphalt coating is conveyed to the spray gun 6 under the action of gravity. Then, the high-pressure gas conveyed by the air compressor 2 is ejected from the nozzle 20. The nozzle 20 with a fan-shaped structure can make the ejected asphalt in a uniform fan shape, and can be better attached to the side of the concrete. By turning the flow regulating valve 25, the gas flow can be adjusted, thereby adjusting the spraying amount of the asphalt. By starting the electric push rod 19 to push the slider 18 to slide in the rail groove 17, the height of the spray gun 6 can be adjusted, which can adapt to the spraying construction of the side of concrete with different thicknesses, improving the spraying effect during the asphalt coating process of large-area airfield, and having simple operation and high working efficiency.
