[0023] A support plate 1 is provided on the side of the outer cylinder 5. The upper surface of the support plate 1 is fixedly connected with a top plate 2. The lower surface of the top plate 2 is fixedly connected with a limit strip 20. The height of the lower surface of the limit strip 20 is lower than the height of the upper surface of the slider 12, restricting the movement area of the slider 12.

[0024] Working principle: During use, solid asphalt is put into the inner cylinder 26. When the asphalt is heated by the heating rod on another inner cylinder 26, the first liquid pump 17 and the second liquid pump 18 pump out the water in the outer cylinder 5 and transport it to the water tank 10 to complete the cycle. At the same time, another first liquid pump 17 transports the water back into the outer cylinder 5 to heat the inner cylinder 26, realizing the preheating of the solid asphalt. The asphalt in the other inner cylinder 26 is then discharged through the discharge pipe 16. Subsequently, the motor 22 drives the stirring blades 24 to rotate rapidly, causing the asphalt on the stirring blades 24 to fall off. Then, the hydraulic cylinder 13 drives the entire stirring device to rise. Under the action of the lead screw 11 and the limit strip 20, it moves above the preheated inner cylinder 26. At this time, the asphalt in this inner cylinder 26 is in a liquid state after preheating, and the heating rod 27 continues to heat it. The hydraulic cylinder 13 drives the stirring device to descend. Under the detection of the obstacle detector 15, the electric telescopic rod 9 drives the sealing plate 25 to retreat, enabling the stirring device to enter the inner cylinder 26. The second fixing plate 29 is larger than the diameter of the feeding port, which can determine the position of the stirring device and recover the waste heat through the same principle.
