[0019] In this embodiment, the asphalt storage tank 2 is used to store asphalt. As needed, heating components or insulation components can be added inside the asphalt storage tank 2 to continuously heat the asphalt and prevent it from solidifying. The heating components are electric heating tubes that are evenly distributed on the inner wall of the asphalt storage tank 2. The insulation components are rock wool insulation layers that are wrapped around the outside of the asphalt storage tank 2 to continuously heat and keep the asphalt warm, preventing the asphalt from solidifying and caking due to temperature drop during storage.

[0020] Please see Figure 1 and Figure 2 One end of the mobile frame 1 is fixedly connected to an auxiliary handle 3. The mobile wheel 14 drives the entire equipment to move along the road. One end of the mobile frame 1 is fixedly connected to an auxiliary handle 3. The auxiliary handle 3 is covered with an anti-slip rubber sleeve, which makes it easier for the operator to push the equipment and improves the comfort and stability of operation.

[0021] In this embodiment, the heating component is electrically connected to a temperature controller, which is fixedly mounted on the auxiliary handle 3. The temperature controller is equipped with a temperature display screen and adjustment buttons, and the operator can monitor the temperature inside the asphalt storage tank 2 in real time through the temperature controller.

[0022] Please see Figure 1 and Figure 3The shaft 13 and the discharge box 9 are rotatably connected. The shaft 13 and the discharge box 9 are rotatably connected by bearings to ensure that the shaft 13 rotates smoothly and avoids asphalt leakage. Both ends of the shaft 13 are equipped with casters 14. The discharge box 9 and the asphalt storage box 2 are connected by a connection port 10. A solenoid valve is installed in the connection port 10. In this embodiment, the asphalt is conveyed from the asphalt storage tank 2 to the discharge box 9 by controlling the opening and closing of the solenoid valve, so asphalt paving is precisely controlled. The bottom of the mobile frame 1 is rotatably connected to two rotating shafts 13, one of which passes through the discharge box 9. A rotating cylinder 12 is fixedly connected to the outside of the rotating shaft 13, and the rotating cylinder 12 is set inside the discharge box 9. A cleaning assembly is provided on one side of the discharge box 9. The cleaning assembly includes a fixing plate 6 and a blower 18. A duct 16 for discharging air is provided at the bottom of the fixing plate 6.

[0023] Please see Figure 3 and Figure 4 The fixed plate 6 is fixedly connected to the mobile frame 1. The fixed plate 6 is fixedly connected to the battery 15. The blower 18 is fixedly connected to the top of the fixed plate 6. The bottom end and both sides of the air duct 16 are provided with air vents 17. The top end of the air duct 16 is connected to the air outlet of the blower 18. The air generated by the blower 18 is blown out through the air vents 17 of the air duct 16 to achieve all-round cleaning of the road surface.

[0024] In this embodiment, a discharge port 11 is provided at the bottom of the discharge box 9. The opening of the discharge port 11 gradually narrows at the bottom, and a gap is left between the outer side of the rotating drum 12 and the top of the discharge port 11, forming a narrow-slit discharge structure. The width of the gap can be adjusted according to the thickness of the asphalt paving. The rotating drum 12 is used to press and grind the falling asphalt to ensure that the asphalt is discharged evenly.

[0025] Please see Figure 1 and Figure 2 A cleaning assembly is provided between the discharge box 9 and the fixed plate 6. The cleaning assembly includes a fixed frame 7, which is fixedly connected to the inside of the movable frame 1. A cleaning roller 8 is rotatably connected inside the fixed frame 7. A brush is provided on the outside of the cleaning roller 8, and the end of the brush is attached to the ground. A connecting frame 4 is provided on the side of the discharge box 9 away from the fixed plate 6. A pressure roller 5 is rotatably connected inside the connecting frame 4.

[0026] In this embodiment, the road surface is mechanically swept by the rotation of the cleaning roller 8 to remove residual waste and debris.

[0027] Working principle: Pour asphalt into the asphalt storage tank 2 and start the blower 18. As the personnel push the whole device toward the crack in the road surface, the cleaning component will first pass through the cracked road surface. The wind generated by the air outlets 17 on both sides of the air duct 16 can blow away the dust and small stones on the road surface to both sides, while the downward air outlets 17 at the bottom of the air duct 16 can blow out the impurities in the crack. Subsequently, the cleaning assembly passes by, removing residual waste through friction between the brush and the ground. When the discharge box 9 passes through the road surface gap, the solenoid valve is opened, and the asphalt inside the asphalt storage tank 2 is discharged downwards. As the device moves, the rotating shaft 13 rotates accordingly, and the rotating shaft 13 drives the rotating drum 12 to rotate inside the discharge box 9. Through the gap between the drum and the discharge port 11, the falling asphalt is pressed and ground, which can make the discharged asphalt uniform and at the same time avoid the formation of lumps inside the asphalt.

[0028] After the asphalt is laid, the entire device moves, and the pressure roller 5 presses the laid asphalt to make it smoother.

[0029] In the above scheme, it should be noted that: the solenoid valve, blower 18, temperature sensor and battery 15 in this application are all existing products. The battery 15 provides power to the solenoid valve and blower 18. The specific structure, electrical connection method (circuit layout) and working principle of the solenoid valve, blower 18, temperature sensor and battery 15 are all existing publicly disclosed technical means. It should also be noted that this application is also equipped with existing control buttons, which are connected to the solenoid valve and blower 18 via wires to regulate the operating status of the solenoid valve and blower 18.
