These materials of different quality and quantity are mixed to form different structures and have different mechanical properties.

[0003] In the related technology, by setting a second motor, gears and a stirring shaft, when stirring the asphalt inside the mixing box, people control the operation of the second motor through a control switch, which in turn drives the gears to rotate, and at the same time drives the rotating shaft and the stirring shaft to rotate, so as to fully stir the asphalt inside the mixing box. Under the action of the second motor, gears and stirring shaft, it is easier for people to stir the asphalt.

[0031] When the auger 5 rotates to transport the asphalt mixture, the auger 5 drives the driving wheel 91 to rotate, and the driving wheel 91 drives the driven wheel 92 to rotate through the belt 93, and the driven wheel 92 can drive the rotation of the dredging rod 7 and the dredging plate 8. Driven by the rotation of the dredging plate 8, the asphalt mixture can be dredged to avoid blockage of the asphalt mixture, facilitate the discharge of the asphalt mixture, and improve the discharge efficiency of the asphalt mixture.
