[0029] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment: an asphalt storage tank for highway construction, comprising a bracket 1, a heating tank 2 being mounted on the top of the bracket 1, and the bracket 1 supporting and fixing the heating tank 2, which can keep the heating tank 2 away from the ground in the construction area, thereby effectively preventing the heating tank 2 from getting wet. A side cover 5 is mounted on one side of the heating tank 2, and a connecting disc 9 is rotatably connected to the middle of the side cover 5, and a bevel gear 6 is fixedly connected to one end of the connecting disc 9, and the connecting disc 9 passes through the interior of the side cover 5. A sliding rod 7 is slidably connected to the middle of the connecting disc 9, and a plurality of limit bars 8 are fixedly connected to the outer periphery of the sliding rod 7. When the connecting disc 9 rotates, the sliding rod 7 can be driven to rotate by the limit bars 8. A rotating rod 10 is fixedly connected to one end of the sliding rod 7, and a plurality of stirring rods 11 are fixedly connected to the outer periphery of the rotating rod 10. When the stirring rods 11 rotate, the asphalt stored in the heating tank 2 can be stirred, and the fluidity of the asphalt can be effectively guaranteed in conjunction with the electric heating component inside the heating tank 2.

[0031] Reference Figure 1 、 Figure 3 and Figure 4 The other end of the slide bar 7 is rotatably connected to a connecting rod 19, and the end of the connecting rod 19 away from the slide bar 7 is fixedly connected to a slide 18, so that when the slide bar 7 is driven to rotate by the connecting disk 9, the slide bar 7 can also be pulled by the connecting rod 19 to slide back and forth inside the connecting disk 9. The middle side of the inner wall of the bracket 1 is rotatably connected to a rotating block 12, and the side of the side cover 5 away from the heating tank 2 is fixedly connected to a fixed frame 14. The middle part of the fixed frame 14 is rotatably connected to a pulley 15, and the side of the pulley 15 away from the fixed frame 14 is fixedly connected to a bevel gear 6, and the two bevel gears 6 are meshed. The side of the fixed frame 14 away from the side cover 5 is fixedly connected to a motor 25, and the output end of the motor 25 is fixedly connected to a turntable 16. The turntable 16 and the pulley 15 are connected by a belt. When the motor 25 is started, it can drive the turntable 16 to rotate. When the turntable 16 rotates, the pulley 15 is driven to rotate synchronously through the belt, so that the bevel gear 6 installed on the pulley 15 can drive the connecting plate 9 to rotate, and then drive the rotating rod 10 and the stirring rod 11 to rotate. An eccentric shaft 17 is fixedly connected to one side of the edge of the turntable 16, so that the rotation of the turntable 16 can drive the eccentric shaft 17 to move in a circular motion, and the eccentric shaft 17 drives the slide 18 and the connecting rod 19 to continuously reciprocate, thereby driving the slide bar 7, the rotating rod 10 and the stirring rod 11 to continuously reciprocate.

[0032] Reference Figure 1 、 Figure 3 and Figure 4 A scraper assembly is installed inside the heating tank 2. The scraper assembly can effectively prevent residual asphalt from condensing or adhering to the inner wall of the heating tank 2, thereby avoiding asphalt waste. A support sleeve 13 is fixedly connected to the middle of the rotating block 12. The end of the rotating rod 10 away from the slide rod 7 is sleeved inside the support sleeve 13. The cooperation between the rotating rod 10 and the support sleeve 13 is connected by a spline shaft, ensuring that the rotating rod 10 can slide inside the support sleeve 13 through the spline shaft, and can also drive the support sleeve 13 to rotate through the spline shaft at the end of the rotating rod 10, thereby synchronously allowing the two connecting rings 20 to rotate together. The outer periphery of the eccentric shaft 17 is slidably connected to the inside of the slide 18, and the outer side of the limit bar 8 is slidably connected to the inside of the connecting disk 9. The circular motion of the eccentric shaft 17 drives the slide 18 to reciprocate, so that the stirring rod 11 can rotate and stir the asphalt while shaking the asphalt back and forth, ensuring that the stored asphalt always maintains uniform fluidity. A feed port 3 is installed on the top of the heating tank 2, and a discharge port 4 is installed on the bottom of the heating tank 2. The asphalt enters the heating tank 2 through the feed port 3 for storage, and can be taken out through the discharge port 4 when in use.

[0033] Reference Figure 2 、 Figure 4 and Figure 5 The scraper assembly includes two connecting rings 20, one of which is fixedly connected to the outer periphery of the connecting disk 9, and the other connecting ring 20 is fixedly connected to the outer periphery of the rotating block 12. A plurality of cross frames 21 are fixedly connected to the edges of the two connecting rings 20, and a limit plate 22 is slidably connected inside the cross frame 21. A scraper 23 is fixedly connected to one side of the limit plate 22, and a plurality of springs 24 are provided on the other side of the limit plate 22. The connecting disk 9 will drive one of the connecting rings 20 to rotate, and then drive the two connecting rings 20 to rotate synchronously under the connection of the cross frame 21, so that the cross frame 21 can perform a circular motion inside the heating tank 2. As the cross frame 21 moves in a circular motion, the spring 24 inside the cross frame 21 will tightly press the limit plate 22, so that the limit plate 22 pushes the scraper 23 to fit tightly against the inner wall of the heating tank 2. With the movement of the cross frame 21, the scraper 23 can move in a circular motion along the inner wall of the heating tank 2 to scrape off the asphalt condensed and attached to the inner wall of the heating tank 2. The scraper 23 passes through the cross frame 21 and abuts against the inner wall of the heating tank 2, allowing the scraper 23 to cling closely to the inner wall of the heating tank 2, preventing a large amount of asphalt from condensing or adhering to the inner wall of the heating tank 2. This avoids asphalt waste and facilitates subsequent cleaning of the interior of the heating tank 2. One end of a spring 24 is fixedly connected to the side of the limit plate 22 near the rotating rod 10, and the other end of the spring 24 is fixedly connected to the inner wall of the cross frame 21. The spring 24 ensures that the scraper 23 clings closely to the inner wall of the heating tank 2 and, when the scraper 23 is worn, can always push the scraper 23 to keep in contact with the inner wall of the heating tank 2.

[0034] Working principle: When asphalt is stored inside the heating tank 2, the heating tank 2 is started to heat and insulate the asphalt inside it to prevent the asphalt from solidifying. At the same time, the motor 25 is started to rotate the bevel gear 6 on the pulley 15 by rotating the turntable 16, and then the connection disk 9 is driven to rotate through the engagement of the two bevel gears 6. The rotation of the connection disk 9 will drive the slide bar 7 to rotate through the cooperation of the limit bar 8, and then the slide bar 7 will drive the rotating rod 10 and the stirring rod 11 on its periphery to rotate inside the heating tank 2, stirring the heated and insulated asphalt inside the heating tank 2, and further preventing it from solidifying. At the same time, the rotation of the turntable 16 will also drive the eccentric shaft 17 to perform circular motion, so that the eccentric shaft 17 can pull the slide 18 to move. Since the slide 18 is connected to the slide bar 7, the eccentric shaft 17 can drive the slide 18 and the connecting rod 19 to move back and forth. The connecting rod 19 pulls the sliding rod 7 and the rotating rod 10 and the stirring rod 11 inside the heating tank 2 to move back and forth, so that the stirring rod 11 can rotate to stir the asphalt while also shaking continuously to allow the asphalt to be stirred evenly, ensuring that the asphalt stored inside the heating tank 2 maintains uniform and stable fluidity and can be directly taken out when used.

[0035] When the motor 25 drives the connecting disk 9 to rotate, the connecting disk 9 will also synchronously drive one of the connecting rings 20 to rotate, and then drive the two connecting rings 20 to rotate synchronously under the connection of the cross frame 21, so that the cross frame 21 can perform a circular motion inside the heating tank 2. As the cross frame 21 moves in a circular motion, the spring 24 inside the cross frame 21 will tightly press the limit plate 22, so that the limit plate 22 pushes the scraper 23 to fit tightly against the inner wall of the heating tank 2. As the cross frame 21 moves, the scraper 23 can move in a circular motion along the inner wall of the heating tank 2 to scrape off the asphalt that has condensed and adhered to the inner wall of the heating tank 2, and re-mix it with the asphalt inside the heating tank 2, so as to avoid asphalt remaining inside the heating tank 2 and asphalt adhering to the heating tank 2 and causing waste.

[0036] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
