During paving, after the asphalt concrete is discharged from the bottom of the feed hopper, as the device moves as a whole, the scraper first scrapes the asphalt concrete flat, and then the pressure roller compacts the asphalt concrete.
[0008] Preferably, the two fixing plates are respectively connected and fixed to the outer walls on both sides of the feed hopper, and symmetrically distributed through holes are provided on the outer wall on one side of the fixing plate and the outer walls on both ends of the scraper.

[0011] The two fixing plates are connected to the scraper through a connecting piece, so as to facilitate the subsequent replacement of the scraper.
[0012] Preferably, a servo motor is installed on the top of the fixing frame, and the output shaft of the servo motor is connected and fixed to the top end of the stud.
[0013] The stud is driven to rotate by a servo motor.
[0014] Preferably, the length of the guide rod is the same as that of the stud, and a limiting block is fixed at the bottom of the guide rod.
[0015] The limit blocks fixed at the bottom of the two guide rods can limit the movement of the adjustment plate to prevent the adjustment plate from being separated from the studs.
[0016] Preferably, both ends of the top of the adjustment plate are provided with sliding holes that form a sliding fit with the guide rod, and both ends of the adjustment plate are symmetrically fixed with fixing rods that form a plug-in fit with the bracket.
[0017] The adjusting plate slides along the rod wall of the guide rod, and the height position of the adjusting plate can be adjusted by cooperating with the rotation of the stud.
[0018] The beneficial effects of the utility model are:
[0019] The stud is driven by a servo motor to rotate, and the adjustment plate slides along the rod wall of the guide rod. In coordination with the rotation of the stud, the rotating stud drives the height position of the screwed adjustment plate to adjust the paving thickness of the discharged asphalt concrete. During paving, after the asphalt concrete is discharged from the bottom of the feed hopper, as the device moves as a whole, the scraper first flattens the asphalt concrete, and then the pressure roller compacts the asphalt concrete. This effectively solves the problem that the prior art cannot control the paving thickness according to the actual requirements of the road, resulting in the paved road surface being too thick, and workers are required to manually repair the uneven thickness areas, thereby increasing the labor intensity of workers.
