The reciprocating threaded rod 13 is threadedly connected to a circular ring plate 14 below. The driving motor 3 drives the first bevel fan 6 to rotate inside the discharge pipe 5 through the driving rod 4. The driving rod 4 drives the second bevel fan 10 to rotate through the first gear 7 and the rack belt 8. The first bevel fan 6 and the second bevel fan 10 rotate to control the asphalt discharge speed inside the discharge pipe 5. The driving rod 4 also drives the first bevel gear 11 to rotate. The first bevel gear 11 drives the reciprocating threaded rod 13 to rotate through the second bevel gear 12. The reciprocating threaded rod 13 uses a threaded connection relationship to drive the circular ring plate 14 to move on the inner wall of the discharge pipe 5 and remove sticky asphalt.

[0033] The L-shaped fixed plate 2 is fixedly connected to the drive motor 3, and the rack belt 8 is meshed with the second gear 9 on the side away from the first gear 7.
