The setting of the rotating motor 203 can better drive the first gear 204 to rotate, and then through the mutual cooperation between the first gear 204 and the subsequent components, it can drive the rotating ring 201 and the subsequent components to rotate, thereby realizing the rotational spraying of asphalt.

[0025] The outer surface of the pipe 1 is fixedly connected to a second fixing ring 208, and the outer surface of the second fixing ring 208 is fixedly connected to a connecting block 209, and the outer surface of the connecting block 209 is rotatably connected to an adjusting plate 2010 via a pin shaft.
