At the same time, the materials required for making asphalt are connected to the inside of the mixing barrel 200, and then the motor 401 is started. The output shaft of the motor 401 rotates to drive the second rotating shaft 401a to rotate through the coupling, and the rotation of the second rotating shaft 401a will drive the worm gear 401b and the first toothed disc 401c on its outer wall to rotate synchronously, wherein the rack on the outer wall of the first toothed disc 401c meshes with the rack on the outer wall of the adjacent first toothed ring 502a, so that When the first toothed disc 401c rotates, it will drive the first toothed ring 502a to rotate synchronously, and the rotation of the first toothed ring 502a will drive the rotating seat 502 at its bottom to rotate, so that the stirring blade 508 rotates with the first toothed ring 502a as the center of the circle, and the bottom of the rotating seat 502 is connected to the surface of the lifting plate 503 through the auxiliary telescopic rod 502b, so the rotation of the rotating seat 502 will drive the lifting plate 503 to rotate synchronously under the action of the auxiliary telescopic rod 502b.
