[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1-3 As shown, a mixing device for producing self-healing asphalt pavement material includes a trolley 1, a barrel 2 fixedly connected to the top of the trolley 1, a sleeve 12 rotatably connected to the middle of the top of the barrel 2, an installation shaft 8 inside the sleeve 12, multiple sets of mixing rods 9 fixedly connected to the lower middle part of the installation shaft 8, a feeding plate 10 fixedly connected to the upper middle part of the installation shaft 8, a limit mechanism between the sleeve 12 and the installation shaft 8, a driving mechanism installed on the outside of the sleeve 12, a ring 18 fixedly connected to the top of the barrel 2, and the top of the ring 18 is uniformly provided with an arc-shaped concave-convex structure. The ring 18 is concentric with the installation shaft 8. Connecting arms 20 are fixedly connected to the front and rear sides of the top of the installation shaft 8. Rollers 19 are installed at the ends of the connecting arms 20 and are located on the upper surface of the ring 18. Multiple scrapers 11 are fixedly connected to the bottom of the feeding plate 10, and the sides of the scrapers 11 are in contact with the inner wall of the barrel 2.

[0023] Raw materials are fed into the barrel 2 and fall onto the feed plate 10. The drive mechanism drives the sleeve 12 to rotate. The rotating sleeve 12 drives the mounting shaft 8 to rotate through the limiting mechanism. The rotating mounting shaft 8 drives the connecting arm 20 and the roller 19 to rotate. The roller 19 rolls on the surface of the ring 18. Since the surface of the ring 18 is provided with an arc-shaped concave-convex structure, the height of the roller 19 changes during the movement, thereby causing the mounting shaft 8 and the feed plate 10 to move up and down, dropping the raw materials to the bottom of the barrel 2. The rotating mounting shaft 8 causes the stirring rod 9 to rotate, stirring the raw materials. The scraper 11 rotates with the feed plate 10 to assist in stirring and scrapes the material off the inner wall of the barrel 2 during unloading.

[0024] Specifically, such as Figure 3 As shown, the limiting mechanism includes multiple slide grooves 13, which are formed inside the sleeve 12. Each slide groove 13 has a slider 14 slidably connected inside it, and the slider 14 is fixedly connected to the outside of the mounting shaft 8. When the mounting shaft 8 moves up and down, the slider 14 slides up and down inside the slide groove 13. The horizontal rotation of the sleeve 12 can drive the slider 14 through the slide groove 13 to drive the mounting shaft 8 to rotate.

[0025] Specifically, such as Figure 3 As shown, the drive mechanism includes a motor 16, which is fixedly connected to the top of the barrel 2. The output end of the motor 16 is fixedly connected to a drive pulley 17. The drive pulley 17 is connected to a driven pulley 15 via a belt, and the driven pulley 15 is fixedly connected to the outside of the sleeve 12. The belt passes through the ring 18. When the motor 16 works, it drives the drive pulley 17 to rotate. The rotating drive pulley 17 causes the driven pulley 15 to rotate via the belt, thereby causing the sleeve 12 to rotate.

[0026] Specifically, such as Figure 2 As shown, a base 5 is fixedly connected to the bottom of the barrel 2, and the bottom of the mounting shaft 8 is located inside the base 5. A spring 6 is fixedly connected inside the base 5, and the top of the spring 6 is fixedly connected to the mounting shaft 8. The bottom of the mounting shaft 8 moves inside the base 5, which restricts the movement of the mounting shaft 8 and thus ensures the stability of the operation of the mounting shaft 8. When the mounting shaft 8 moves upward, the spring 6 is stretched, that is, the spring 6 exerts a downward force on the mounting shaft 8, which can make the mounting shaft 8 move downward smoothly when it needs to move downward, forming an up-and-down shaking, and preventing the material inside the barrel 2 from blocking the downward movement of the mounting shaft 8.

[0027] Specifically, such as Figure 2 As shown, a rubber ring 7 is fixedly connected to the top of the base 5, and the rubber ring 7 is sleeved on the outside of the mounting shaft 8. The rubber ring 7 is located between the base 5 and the mounting shaft 8 to prevent materials from entering the interior of the base 5.

[0028] Specifically, such as Figure 1As shown, a water tank 3 is fixedly installed on the top left side of the trolley 1. A water pipe 4 is installed inside the water tank 3, and the top of the water pipe 4 is connected to the barrel 2. A water pump is installed at one end of the water pipe 4. During the mixing and stirring of materials, the water pump sends the clean water in the water tank 3 into the barrel 2 through the water pipe 4.

[0029] Working principle: Raw materials are put into the barrel 2 and fall onto the feed plate 10. The motor 16 drives the drive pulley 17 to rotate. The rotating drive pulley 17 drives the driven pulley 15 to rotate through the belt, which in turn drives the sleeve 12 to rotate. The rotating sleeve 12 drives the mounting shaft 8 to rotate through the slide groove 13 and the slider 14. The rotating mounting shaft 8 drives the connecting arm 20 and the roller 19 to rotate. The roller 19 rolls on the surface of the ring 18. Because the surface of the ring 18 is provided with an arc-shaped concave and convex structure, the height of the roller 19 changes during the movement, which causes the mounting shaft 8 and the feed plate 10 to move up and down, dropping the raw materials to the bottom of the barrel 2. The rotating mounting shaft 8 causes the stirring rod 9 to rotate, stirring the raw materials. During this process, the water pump sends clean water from the water tank 3 into the barrel 2 through the water pipe 4 to mix them.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
