During working, the drying device is moved to the position of a road surface needing drying, and the pull rod 7 is fixed on the tractor, so that the tractor can drive the drying device to move along the road surface. When the drying device moves, the driving motor 3 drives the roller 1 to rotate, so that the roller 1 drives the bucket 4 to rotate. The rotating bucket 4 scoops up the sand on the ground and is stored in the bucket 4. The position of the sand in the bucket 4 changes as the bucket 4 continues to rotate, and the excess moisture on the surface of the sand is sucked up as it passes the water suction mechanism until the sand in the bucket 4 slides down the bucket 4 and into the cavity of the heating frame 8 as the bucket 4 moves to the heating frame 8. The heating frame 8 continuously generates heat, the sand slides downwards along the inner side wall of the heating frame 8 in the heating frame 8, and the sand is continuously heated by the heating frame 8 in the process of sliding, so that the moisture on the surface of the sand is evaporated to dryness.
