DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment: a road repair structure, including a cart 1, a heating pad 2 is fixedly connected to the top of the cart 1, a storage barrel 3 is fixedly connected to the top of the heating pad 2, a feeding pipe 4 is fixedly connected to the top of the storage barrel 3, a motor 5 is fixedly connected to the top of the storage barrel 3, a rotating shaft 9 is fixedly connected to the output end of the motor 5, a support rod 10 is fixedly connected to the outer wall of the rotating shaft 9, a limit plate 12 is slidably connected inside the support rod 10, a scraper 11 is fixedly connected to one side of the limit plate 12, and one side of the scraper 11 is attached to the storage barrel The inner wall of the cylinder 3 and the support rod 10 are fixedly connected with a sealing ring 13, the inner wall of the sealing ring 13 is attached to the outer wall of the scraper 11, the support rod 10 is fixedly connected with a telescopic rod 14, one end of the telescopic rod 14 is fixedly connected to the other side of the limit plate 12, and the outer wall of the telescopic rod 14 is provided with a reset component, which includes a first spring 15, the first spring 15 is sleeved on the outer wall of the telescopic rod 14, one end of the first spring 15 is fixedly connected to the other side of the scraper 11, and the other end of the first spring 15 is fixedly connected to the inside of the support rod 10;

[0033] Specifically, first, the asphalt raw material is placed inside the storage barrel 3 through the feeding pipe 4. The design of the storage barrel 3 should ensure the fluidity of the asphalt therein, so as to facilitate the subsequent stirring and scraping operations. The design of the feeding pipe 4 should be easy to operate to ensure that the asphalt can flow into the storage barrel 3 stably. Next, the storage barrel 3 is continuously heated by the heating pad 2. This step is crucial because heating can prevent the asphalt from solidifying inside the storage barrel 3. The design of the heating pad 2 should ensure uniform heating effect and ensure safety to avoid equipment failure or safety accidents caused by overheating. While heating, the motor 5 is started, and the output end drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the scraper 11 to scrape off the asphalt attached to the inner wall of the storage barrel 3 through the support rod 10. This design is conducive to maintaining the fluidity of the asphalt, preventing solidification, and ensuring that the scraper 11 can effectively scrape the asphalt from the inner wall. In addition, the scraper 11 and the support rod 10 are sealed by a sealing ring 13. This design can prevent the asphalt from flowing into the support rod 10 through the gap between the scraper 11 and the support rod 10, ensuring the quality of the asphalt and the safe operation of the equipment. Finally, the scraper 11 is supported by the tension of the first spring 15 so that it can always fit on the inner wall of the storage barrel 3. This design is conducive to ensuring that the scraper 11 can maintain a stable position during the stirring process and improve the stirring effect.

[0034] Reference Figure 4 and Figure 5A limiting column 16 is fixedly connected inside the cart 1, and a slider 17 is slidably connected to the outer wall of the limiting column 16. A second spring 18 is sleeved on the outer wall of the limiting column 16. One end of the second spring 18 is fixedly connected to the inside of the cart 1, and the other end of the second spring 18 is fixedly connected to the top of the slider 17. A connecting shaft 20 is fixedly connected to one side of the slider 17. A flattening roller 19 is rotatably connected to the outer wall of the connecting shaft 20. A ball 21 is arranged inside the flattening roller 19. There are multiple balls 21 arranged inside the flattening roller 19. The outer wall of the slider 17 is slidably connected to the inside of the cart 1. A feeding pump 6 is fixedly connected to the inside of the storage barrel 3, and the input end of the feeding pump 6 is fixedly connected to the inside of the storage barrel 3. A discharge pipe 7 is fixedly connected to the output end of the feeding pump 6, and a discharge cover 8 is fixedly connected to one end of the discharge pipe 7;

[0035] Specifically, in the process of asphalt pavement construction, the feed pump 6 plays a vital role. Its input end is responsible for extracting the asphalt inside the storage barrel 3 and pumping it into the discharge pipe 7 through the output end of the feed pump 6. Subsequently, the asphalt is discharged through the discharge cover 8 and laid on the road surface. This process is achieved by the push of the cart 1. In the process of pushing the cart 1, the asphalt is evenly laid on the road surface through the discharge cover 8. Then, the flattening roller 19 plays a role in flattening the asphalt. The flattening roller 19 is connected to the slider 17 through the internal connecting shaft 20. The slider 17 is limited inside the cart 1 by the limit column 16. In order to ensure the flattening effect, the role of the second spring 18 cannot be ignored. It supports the flattening roller 19 through tension so that it always fits tightly on the road surface. In this way, whether rolling or stationary, the flattening roller 19 can maintain a good working condition. It is worth mentioning that the ball 21 inside the flattening roller 19 will fall off during the rolling process, thereby increasing the weight of the flattening roller 19. In this way, the flattening roller 19 can compact the asphalt more effectively each time it rolls, which not only improves the construction efficiency, but also reduces the number of reciprocating flattening times, saving manpower and material resources.

[0036] Working principle: When the pavement repair structure is used, firstly, asphalt raw materials are added into the storage barrel 3 through the feeding pipe 4, and then the heating pad 2 continuously heats the storage barrel 3 to prevent the asphalt inside the storage barrel 3 from solidifying, and then the output end of the motor 5 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the scraper 11 through the support rod 10 to scrape off the asphalt attached to the inner wall of the storage barrel 3, and continuously stirs the asphalt to prevent solidification, and the scraper 11 and the support rod 10 are sealed by the sealing ring 13 to prevent the asphalt from flowing into the support rod 10 through the gap between them. The scraper 11 is supported by the tension of the first spring 15 so that the scraper 11 can always fit the inner wall of the storage barrel 3, and then the supply The input end of the feed pump 6 extracts the asphalt inside the storage barrel 3, and pumps it into the discharge pipe 7 through the output end of the feed pump 6. Then the asphalt is discharged through the discharge cover 8. In the process of pushing the cart 1, the asphalt is laid on the road surface through the discharge cover 8, and then the asphalt is flattened by the flattening roller 19 at the rear. The flattening roller 19 is connected to the slider 17 through the internal connecting shaft 20. The slider 17 is limited inside the cart 1 by the limiting column 16 and is supported by the tension of the second spring 18, so that the flattening roller 19 can always fit the road surface. Then, when the flattening roller 19 rolls, the ball 21 inside will fall down to increase the weight of the flattening roller 19, thereby reducing the number of reciprocating flattening times.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
