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 sand from the ground and is stored in the bucket 4. The position of sand in the bucket 4 is changed in the process of continuously rotating the bucket 4, and redundant water on the surface of the sand is sucked dry when the sand passes through the water suction mechanism until the sand in the bucket 4 slides down from the bucket 4 and enters the inner cavity of the heating frame 8 when the bucket 4 moves to the heating frame 8.
