[0023] See also Figure 1-Figure 3 The driving assembly shown in the figure includes a double-axis motor 10 arranged above the mobile base 1, and the output ends of the double-axis motor 10 are fixed with a driving shaft 11, and one end of the driving shaft 11 is fixed with a first gear 12, and a second gear 13 is fixed on one side of the first gear 12 and at the end of the pressure roller 6, and a third gear 14 is fixed on both ends of the worm 9. The first gear 12, the second gear 13 and the third gear 14 are meshed and connected by a toothed chain 15, and a tensioning assembly is provided on the inner side of the toothed chain 15 and on the side wall of the mobile base 1.

[0024] When paving asphalt for road maintenance: first, put the molten asphalt into the hot melt box 2, heat the asphalt to prevent it from solidifying, and then adjust the scraper 5 and the pressure roller 6 through the lifting component to adjust the thickness of the asphalt paving. After the scraper 5 and the pressure roller 6 are adjusted, start the double-axis motor 10. The start of the double-axis motor 10 can drive the driving shafts 11 at both ends to rotate. The rotation of the driving shaft 11 can drive the first gear 12 to rotate. The first gear 12 is engaged by the tooth chain 15 to drive the second gear 13 and the third gear 14 to rotate, which can drive the rotation of the pressure roller 6. Pushing the mobile base 1 can drive the scraper 5 to move. At this time, the scraper 5 flattens the asphalt poured out of the discharge pipe 3 and then the pressure roller 6 compacts it.

[0025] When the third gear 14 rotates, it can drive the worm 9 to rotate. The rotation of the worm 9 can mesh and drive the worm wheel 8 to rotate. The rotation of the worm wheel 8 drives the rotating rod 7 to rotate. The rotating rod 7 drives the spiral blades 24 in the discharge pipe 3 to output the asphalt in the hot melt box 2, avoiding the accumulation of asphalt at the discharge pipe 3 and causing blockage of the discharge pipe 3, increasing the convenience of discharging from the discharge pipe 3, avoiding the staff from repeatedly clearing the discharge pipe, effectively reducing the staff's intensity, and improving the work efficiency of asphalt paving.
