Embodiment Construction
[0032] In the hot-in-place regeneration process, the road surface is first heated continuously by the road surface heating machine, and then the asphalt pavement is thermally milled by the road surface milling vehicle, and the old road surface is heated and milled to form a trapezoidal ridge of asphalt mixture. In the present invention, the scraper feeder 1 is suspended below the rear end of the milling machine, and the frame of the device is dragged and hung on the rear end of the milling machine simultaneously. The material ridge produced after the milling machine works is transmitted to a plurality of scraper elevators 2 through the scraper feeder 1, and these scraper elevators 2 are respectively transported to each layer of conveying device 4 through the feed port 9; The conveying device 4 on the first floor is under the action of the first driving device, and the chain plate 403 on it conveys the asphalt mixture to the discharge port 13 at the rear. When the screw distribu...
