[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a mixing and homogenizing device for high-temperature rutting-resistant asphalt mixture, including a mixing tank 1 and a mixing rod 9. Positioning tubes 2 are installed on both sides of the mixing tank 1. A rotating shaft 3 is installed inside the positioning tube 2. A main channel 4 is provided inside the rotating shaft 3. A connecting ring 5 is movably installed on the outside of the positioning tube 2. A connecting rod 6 is installed at the bottom end of the connecting ring 5. A bottom plate 7 is installed at the bottom end of the connecting rod 6. A bottom groove 8 is provided at the bottom end of the mixing tank 1.

[0024] Specifically, such as Figure 1 As shown, during use, the bottom plate 7 is suspended on the bottom side of the mixing tank 1 with the assistance of the connecting rod 6 and the connecting ring 5. When the bottom plate 7 is rotated with the help of the connecting rod 6, as the bottom plate 7 separates from the bottom groove 8, the material inside the mixing tank 1 can be discharged to the outside along the bottom groove 8.

[0025] A stirring rod 9 is installed on the outer wall of the rotating shaft 3. Several stirring rods 9 are installed on the outer wall of the rotating shaft 3, and the stirring rods 9 are evenly distributed. A branch channel 10 is provided inside the stirring rod 9. A first pulley 11 is installed on the outer wall of the positioning tube 2. A connecting belt 12 is provided on the outer side of the first pulley 11. A second pulley 13 is provided at the top of the inner side of the connecting belt 12. A first motor 14 is installed on the left side of the second pulley 13. A dispersion tank 15 is installed at the top of the mixing tank 1. A tank cover 16 is installed at the top of the dispersion tank 15. A feeding pipe 17 is installed at the top of the can lid 16. An inner shell 18 is installed at the center of the feeding pipe 17. A second motor 19 is installed inside the inner shell 18. The bottom end of the second motor 19 extends into the interior of the dispersion tank 15. A connecting shaft 20 is installed at the bottom end of the second motor 19. A dispersion platform 21 is installed at the bottom end of the connecting shaft 20. A partition 22 is installed on the inner side wall of the feeding pipe 17. Several partitions 22 are installed on the inner side wall of the feeding pipe 17. The several partitions 22 are arranged in a ring. A through groove 23 is provided at the bottom end of the inside of the feeding pipe 17.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the feeding pipe 17 is divided into multiple spaces with the assistance of the partition plate 22 for feeding different materials. After feeding, the materials can fall into the dispersion tank 15 through the bottom groove 23. When the second motor 19 is started to drive the dispersion platform 21 inside the dispersion tank 15 to rotate, the falling materials come into contact with the rotating dispersion platform 21. With the help of the dispersion platform 21, the materials in contact with it can be dispersed and mixed in all directions to avoid the materials falling directly into the mixing tank 1 and being mixed unevenly.

[0027] Movable circulation components are provided on both sides of the rotating shaft 3. The circulation components include side holes 24, connecting pipes 25, heating heads 26 and external pipes 27. Side holes 24 are provided on both sides of the rotating shaft 3. Connecting pipes 25 are movably installed inside the side holes 24. The left side of the connecting pipes 25 extends to the outside of the rotating shaft 3. Heating heads 26 are installed on the left side of the connecting pipes 25. The bottom end of the heating heads 26 is installed with the external pipes 27.

[0028] Specifically, such as Figure 1 and Figure 4As shown, during use, the outer pipes 27 on the bottom side of the heating heads 26 on both sides of the rotating shaft 3 are connected to the inlet and outlet pipes of the circulation equipment, respectively. With the help of the circulation equipment, a high-temperature medium can be introduced and flow in the main channel 4 inside the rotating shaft 3 and the branch channel 10 inside the stirring rod 9. The stirring rod 9 is heated by the high-temperature medium and comes into direct contact with the material when stirring it, so that the material can be heated from the inside.

[0029] Working principle: During use, the base plate 7, assisted by the connecting rod 6 and the connecting ring 5, is suspended at the bottom of the mixing tank 1 to shield the bottom trough 8. Multiple sets of materials can be added along the feeding pipe 17. When the materials fall into the dispersion tank 15 along the through groove 23, the second motor 19 is started to start the dispersion platform 21 inside the dispersion tank 15 to rotate. The rotating dispersion platform 21 contacts the materials, which can help mix the materials and also evenly disperse the materials to move in all directions, eventually falling into the mixing tank 1. The first motor 14 is started, and with the assistance of the second pulley 13, the first pulley 11, and the connecting belt 12, the rotating shaft is driven. When the shaft 3 rotates, the multiple sets of stirring rods 9 on the outside of the shaft 3 rotate accordingly, which can stir the material inside the mixing tank 1. If it is necessary to heat the material, the outer pipes 27 on the bottom side of the heating heads 26 on both sides of the shaft 3 can be connected to the inlet and outlet pipes of the circulation equipment. With the help of the circulation equipment, a high-temperature medium can be introduced and flow in the main channel 4 inside the shaft 3 and the branch channels 10 inside the stirring rods 9. The stirring rods 9 are heated by the high-temperature medium and come into direct contact with the material when stirring it, so that the material can be heated from the inside. With the cooperation of the outer heating jacket, the heating efficiency is higher.
