[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an asphalt thermal recycling device, comprising a shell 1, a fixed frame 2 fixedly connected to the outer wall of the shell 1, a motor 3 fixedly connected to the upper surface of the fixed frame 2, a bevel gear 4 fixedly provided at the output end of the motor 3, a bevel gear 5 meshing with the tooth end of the bevel gear 4, a sleeve 6 fixedly connected inside the bevel gear 5, the outer wall of the sleeve 6 rotatably connected to the interior of the shell 1 and the fixed frame 2, a connecting disc 7 fixedly connected to the outer wall of the sleeve 6, a scraper 8 fixedly connected to the outer wall of the connecting disc 7, the outer wall of the scraper 8 rotatably connected to the inner wall of the shell 1, a bevel gear 9 meshing with the tooth end of the bevel gear 4, a connecting column 10 fixedly connected inside the bevel gear 9, the outer wall of the connecting column 10 rotatably connected to the inner wall of the sleeve 6, a rotating disc 11 fixedly connected to the outer wall of the connecting column 10, a stirring rod 12 fixedly connected to the outer wall of the rotating disc 11, and a support assembly provided on the lower surface of the shell 1 for supporting the shell 1.

[0025] Specifically, the outer casing 1 provides fixed support for the fixed frame 2, which in turn provides fixed support for the motor 3. When the motor 3 is turned on, it drives the first bevel gear 4 to rotate. The rotation of the first bevel gear 4 drives the second bevel gear 5 to rotate, which in turn drives the sleeve 6 to rotate. Simultaneously, the rotation of the sleeve 6 drives the connecting disc 7 to rotate, which in turn drives the scraper 8 to rotate on the inner wall of the outer casing 1. Furthermore, the rotation of the first bevel gear 4 drives the... The rotation of gear 39 causes the connecting column 10 to rotate on the inner wall of sleeve 6. The rotation of the connecting column 10, in turn, causes the rotating disk 11 and the stirring rod 12 to rotate synchronously, thus stirring the asphalt inside the device. By having the stirring rod 12 and the scraper 8 rotate synchronously in both directions inside the device, it is possible to prevent asphalt and other materials from accumulating on the barrel wall and forming lumps. This ensures that the stirring rod 12 can fully stir the asphalt, avoid dead corners, improve the uniformity of material mixing, and reduce maintenance and cleaning costs.

[0026] Reference Figure 1 The support assembly includes an arc-shaped seat 13, the lower surface of the outer shell 1 is fixedly connected to the upper surface of the arc-shaped seat 13, and a base plate 14 is fixedly connected to the lower surface of the arc-shaped seat 13.

[0027] Specifically, the arc-shaped seat 13 can provide fixed support for the outer shell 1, ensuring the stability of the outer shell 1 during operation, and the base plate 14 can also provide fixed support for the arc-shaped seat 13.

[0028] Reference Figure 3 and Figure 4 A support frame 15 is fixedly connected to the outer wall of the outer shell 1, and a hydraulic cylinder 16 is fixedly connected to the upper surface of the support frame 15. A rack 17 is fixedly connected to the output end of the hydraulic cylinder 16, and a slide rail 18 is slidably connected to the inner wall of the rack 17. The lower surface of the slide rail 18 is fixedly connected to the upper surface of the support frame 15. A rotating gear 19 is meshed with the tooth end of the rack 17, and a rotating column 20 is fixedly connected inside the rotating gear 19. A frame 21 is rotatably connected to both ends of the rotating column 20, and the lower surface of the frame 21 is fixedly connected to the upper surface of the support frame 15. An arc-shaped tooth 22 is meshed with the tooth end of the rotating gear 19, and a connecting plate 23 is fixedly connected to the outer wall of the arc-shaped tooth 22. A hinge 24 is meshed with the tooth end of the arc-shaped tooth 22, and a limit post 25 is rotatably connected inside the hinge 24. Both ends of the limit post 25 are fixedly connected to the inner wall of the frame 21. A storage cylinder 26 is fixedly connected to the upper surface of the frame 21.

[0029] Specifically, the outer shell 1 provides fixed support for the support frame 15. Both the outer shell 1 and the support frame 15 have grooves, allowing the regenerant to enter the device through these grooves. The support frame 15 provides fixed support for the hydraulic cylinder 16. When the hydraulic cylinder 16 is activated, it pushes the rack 17 to slide on the outer wall of the slide rail 18. The slide rail 18 supports the rack 17, ensuring its stability during sliding. The sliding of the rack 17 drives the rotating gear 19 to rotate, which in turn drives the rotating column 20 to rotate on the inner wall of the frame 21. The rotating column 20 supports the rotating gear 19, and the frame 21 supports the rotating column 20. The support frame 15 also supports the frame 21. When the rotating gear 19 rotates, it drives the arc-shaped gear 22 to rotate. The rotation of the arc-shaped teeth 22 also drives the connecting plate 23 to rotate, and the rotation of the connecting plate 23 in turn drives the other arc-shaped teeth 22 to rotate synchronously. At the same time, the rotation of the arc-shaped teeth 22 drives the hinge 24 to rotate on the outer wall of the limiting post 25. The limiting post 25 can limit the hinge 24, allowing the hinge 24 to open an opening when it rotates. The frame 21 can also provide fixed support for the storage cylinder 26, which contains recycling agent. When the hinge 24 rotates and opens an opening, the recycling agent inside the storage cylinder 26 can enter the device through the opening and mix with the asphalt. The timing of the opening and closing of the hinge 24 can control the quantitative addition of the recycling agent. By automatically opening or closing the recycling agent addition port at preset times, the tedious steps of manual operation are eliminated, making the addition of recycling agent more efficient and continuous, and improving the overall production efficiency.

[0030] Working principle: When the device is needed, firstly, open the hydraulic cylinder 16, causing the hydraulic cylinder 16 to push the rack 17 to slide. The sliding of the rack 17 will drive the rotating gear 19 to rotate, and the rotation of the rotating gear 19 will also drive the arc-shaped teeth 22 to rotate. At the same time, the rotation of the arc-shaped teeth 22 will drive the connecting plate 23 to rotate, and the rotation of the connecting plate 23 will drive the other arc-shaped teeth 22 to rotate synchronously. The rotation of the arc-shaped teeth 22 will also drive the hinge 24 to rotate on the outer wall of the limiting post 25, opening an opening so that the regenerant inside the storage cylinder 26 can enter the device through the opening. Then, turn on the motor 3, causing the motor 3 to drive the bevel gear 4 to rotate. The rotation of the bevel gear 4 will then drive the bevel gear 5. The rotation of bevel gear 3 (9) and bevel gear 2 (5) in turn drives the connecting column 10 and sleeve 6 to rotate. Simultaneously, the rotation of sleeve 6 and connecting column 10 drives the rotating disk 11 and connecting disk 7 to rotate synchronously in both directions. The rotation of rotating disk 11 and connecting disk 7 in turn drives the scraper 8 and stirring rod 12 to rotate synchronously in both directions, thus mixing and stirring the asphalt and recycling agent. In other words, this device can not only open the opening by rotating hinge 24, eliminating the tedious steps of manual operation and making the addition of recycling agent more efficient and continuous, thereby improving production efficiency, but also prevent asphalt from accumulating on the barrel wall, reduce mixing dead zones, and improve the uniformity of material mixing through the synchronous bidirectional rotation of stirring rod 12 and scraper 8.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
