[0028] Reference Figure 1-11As shown, the utility model is a road leveling machine. When working, first, the truck pours the asphalt mixture into the hopper device 10, and then the scraper feeding device 2 starts to transport the asphalt mixture in the hopper device 10. If the scraper feeding device 2 has a material jam problem during the material transportation process, the impact device 14 is started. When the impact device 14 is running, first, the motor 1401 is started, and the motor 1401 drives the rotating shaft 1402 to rotate.

The support wheel 2 1504 During the movement of the transmission belt 1508 between the support wheel 1505 and the support wheel 1506, the transmission belt 1508 passes through the scraper support 1510. When the transmission belt 1508 passes through the scraper support, the asphalt mixture adhered to the transmission belt 1508 is blocked by the scraper support and falls onto the scraper conveyor. In this way, each closing of the hopper device 10 can complete the cleaning of the asphalt mixture on the hopper device 10. When the cleaning is completed, the hopper cylinder 13 is recovered to drive the left hopper 11 and the right hopper 12 to fall back. When the left hopper 11 and the right hopper 12 fall back, the synchronous motor 2 1501 starts and starts to drive the winding wheel 1502 to rotate. When the winding wheel 1502 rotates, the transmission belt 1508 starts to move back. The transmission belt 1508 wants to move back and the traction rope 1509 moves back.When the left hopper 11 and the right hopper 12 return to their initial positions, the synchronous transmission belt 1508 and the traction rope 1509 return to their initial states. During the movement of the transmission belt 1508, the support wheels 1503, 1504, 1505, 1506, and 1507 mainly play the role of tensioning and supporting the transmission belt 1508.
