An electric push rod mounting end 14 is fixedly connected to the top end of the cavity. A push rod movable end 15 is slidably connected to the lower end of the push rod mounting end 14. The lower end of the movable end 15 is rotatably connected to a vertical shaft 16. The vertical shaft 16 is rotatably connected to an elastic wheel 17. A scraper conveyor 3 is fixedly connected to the upper surface of the vehicle body 1. The push rod mounting end 14 and the movable end 15 are connected to an external power source and then activated.

[0023] A roller 5 is rotatably connected between two brackets 2 on the left side of the lower surface of the vehicle body 1. A front roller 18 is fixedly connected to the outer surface of the roller 5. A first traction arm 6 is rotatably connected to the outer surface of the vehicle body 1 on the right side. A rotating shaft 7 is rotatably connected to the middle of the first traction arm 6. A spiral spreader 8 is rotatably connected to the inner side of the rotating shaft 7. The axes of the rotating shaft 7 and the spiral spreader 8 are aligned. The spiral spreader 8 divides the asphalt and evenly distributes it to both sides, ensuring that the asphalt is evenly and continuously spread on the road surface, avoiding squeezing or holes and improving the smoothness of the road surface.

[0024] The inner side of the end of the No. 1 traction arm 6 away from the vehicle body 1 is rotatably connected to the No. 2 traction arm 11. The inner side of the left end of the No. 2 traction arm 11 is rotatably connected to the ironing plate 9. The inner side of the right end of the No. 2 traction arm 11 is provided with a flat plate 12. The flat plate 12 and the vibrating device 13 cooperate to achieve the effect of a flat plate vibrator.

[0025] A vibrating device 13 is fixedly connected to the upper surface of the flat plate 12. The flat plate 12 and the vibrating device 13 cooperate to achieve the effect of a flat plate vibrator.

[0026] An electric heating plate 10 is provided inside the lower end of the screed plate 9. The electric heating plate 10 is connected to an external power source and then started. Its main function is to generate heat to prevent asphalt from adhering to the surface of the screed plate 9.

[0027] The upper surface of the scraper conveyor 3 is fixedly connected with a hopper 4. The hopper 4 is used to hold asphalt, and an outlet is provided below the scraper conveyor 3.

[0028] Working principle: Before the work starts, put the prepared asphalt recycled concrete into the hopper 4, and then start working.

Then the No. 1 traction arm 6 drives the spiral paver 8 to spread the asphalt recycled concrete, so that it is evenly and continuously spread on the road surface to avoid extrusion or holes and improve the flatness of the road surface. Then adjust the angle of the ironing board 9 to make the asphalt When the thickness of the asphalt on the ground reaches the requirement, the electric heating plate 10 is turned on to start heating to prevent the asphalt from sticking.
