A cylinder 11 is fixedly connected to the right side of the second conical gear 13. The cylinder 11 penetrates through the L-shaped plate 10 and is fixedly connected with a first conical gear 12. A hollow block 15 is rotatably connected to the bottom of the inner wall of the L-shaped plate 10. A second electric telescopic rod 18 is fixedly connected to the bottom of the L-shaped plate 10. The telescopic end of the second electric telescopic rod 18 is rotatably connected to the hollow block 15. A rotating column 16 is rotatably connected to the inner wall of the hollow block 15. A fourth conical gear 17 is fixedly connected to the right side of the rotating column 16. The fourth conical gear 17 is meshed with the first conical gear 12. A plurality of stirring blades 19 are fixedly connected to the right side of the outer wall of the rotating column 16. A safety door 20 is rotatably connected to the right side of the box body 8. A hole 31 is provided in the middle of the left side of the top of the box body 8. A cleaning mechanism 2 is provided on the top of the box body 8;

[0026] Specifically, by starting the microwave heater 7, the waste asphalt mixture in the conical heating pot 4 can be effectively heated, causing the asphalt to fully melt into a liquid state and smoothly discharged through the drain port 6. At the same time, by operating the start of the DC motor 9, the L-shaped plate 10 can be driven to rotate, thereby driving the relevant structures above it to rotate synchronously. During this process, as the L-shaped plate 10 rotates, the second bevel gear 13 rotates on the L-shaped plate 10 through meshing connection with the third bevel gear 14, thereby driving the synchronous rotation of the cylinder 11 and the first bevel gear 12. To further optimize the heating effect, by operating the second electric telescopic rod 18, the hollow block 15 is rotated towards the bottom, so that the right part of the rotating column 16 smoothly enters the conical heating pot 4. Through the meshing action of the first bevel gear 12 and the fourth bevel gear 17, the rotating column 16 rotates and drives the stirring blades 19 to stir the asphalt mixture in the conical heating pot 4 to ensure that the asphalt mixture is fully heated. When the drain port 6 stops flowing out the asphalt liquid, it indicates that the heating process is completed.

[0028] Specifically, first, the asphalt mixture needs to be put into the cleaning box 201. Subsequently, it is rinsed using the spray head 203. This is aimed at effectively removing the dust, soil, and other impurities therein. During the rinsing process, the impurities will, through the action of the filter plate 202, gather at the bottom of the cleaning box 201 and be discharged through the sewage pipe 205. Further, by starting the servo motor 206, the baffle door 207 can be driven to rotate, thereby opening an outlet of the cleaning box 201. During this process, the rinsed asphalt mixture will, under the guidance of the U-shaped guide plate 208, smoothly flow into the conical heating pot 4 through the hole 31, which can significantly reduce various sundries in the asphalt mixture, thereby improving the overall recycling quality and ensuring the efficiency and effect of subsequent processing.

[0029] Refer to Figure 1 and Figure 2 , on the rear side of the inner wall of the box body 8, a smoke alarm 21 is fixedly connected; on the right side of the safety door 20, a handle 22 is fixedly connected, and on the outer side of the handle 22, an anti-slip sleeve 23 is fixedly connected; on the right side of the top end of the box body 8, an alarm lamp 24 is fixedly connected, and on the left and right sides of the outer wall of the alarm lamp 24, alarm speakers 25 are fixedly connected; in the middle of the front end of the box body 8, an observation window 26 is opened, and on the outer side of the observation window 26, an outer frame 27 is fixedly connected;

[0030] Specifically, through the smoke alarm 21, an alarm can be issued when the internal heating is too high and a fire is caused. Through the handle 22, it is convenient to open the safety door 20.

Through the protective cover 30, dust and the like can be prevented from entering the inside of the controller 28 and causing damage to its internal electronic components.

[0033] Working principle: Before using this device, first, place the waste asphalt mixture in the conical heating pot 4, close the safety door 20, and heat the waste asphalt mixture in the conical heating pot 4 by starting the microwave heater 7. The asphalt in the conical heating pot 4 melts into a liquid and is discharged through the drain port 6. By starting the DC motor 9, the L-shaped plate 10 can be driven to rotate, and the structure above the L-shaped plate 10 will rotate together. During the rotation of the second bevel gear 13 above the L-shaped plate 10, through the meshing connection with the third bevel gear 14, the second bevel gear 13 rotates on the L-shaped plate 10, thereby driving the cylinder 11 and the first bevel gear 12 to rotate. Start the second electric telescopic rod 18 to make the hollow block 15 rotate towards the bottom, so that the right side of the rotating column 16 enters the conical heating pot 4. Through the meshing of the first bevel gear 12 and the fourth bevel gear 17, the rotating column 16 rotates, and drives the stirring blade 19 to stir the inside of the conical heating pot 4, so that the asphalt mixture is fully heated. When the drain port 6 stops flowing out, turn off the microwave heater 7, open the safety door 20, push a trolley in. At this time, start the first electric telescopic rod 3, which can push the conical heating pot 4 to pour towards the trolley, so as to pour out the waste residue, so that the asphalt can be fully dissolved and discharged. And through the cleaning mechanism 2, pour the asphalt mixture into the cleaning box 201, and rinse it through the nozzle 203, so that impurities such as dust and soil can be rinsed off, and fall on the bottom of the cleaning box 201 through the filter plate 202, and are discharged through the sewage pipe 205. By starting the servo motor 206, the baffle door 207 can be driven to rotate, so as to open an outlet of the cleaning box 201. The cleaned asphalt mixture passes through the U-shaped guide plate 208 and falls into the conical heating pot 4 through the hole 31, thereby reducing the sundries in the asphalt mixture and improving the recycling quality.
