A discharge port 20 is provided at the side end of the mixing cylinder 1, and the blocking plate 19 is used to block the discharge port 20. When the stirring blade 13 rotates, the stirring blade 13 will drive the asphalt to move forward, and then the asphalt is blocked by the mixing cylinder 1 to reflux, so that the asphalt can be fully stirred. In order to better heat the asphalt, the stirring A heating wire is provided inside the mixing blade 13, and the power supply box 11 supplies power to the heating wire. The heating wire generates heat when it runs, and the heat is transferred to the asphalt through the mixing blade 13. When the mixing blade 13 stirs the asphalt, the heating wire arranged in the mixing blade 13 heats the asphalt, thereby improving the working efficiency of heating the asphalt. When the asphalt and coke particles are mixed, the staff removes the sealing plate 19 from the mixing drum 1, and the sealing plate 19 rotates, and the sealing plate 19 drives the hinge seat 18 to rotate.
