Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt processing technology, specifically to an asphalt anti-rutting agent addition device. Background Technology
[0002] Under high temperatures and continuous heavy loads, asphalt pavements undergo significant permanent deformation, resulting in rutting. This not only affects the smoothness and driving safety of the pavement but also its service life and overall quality. Adding anti-rutting agents to asphalt mixtures is an effective way to prevent rutting and extend pavement service life. These agents are typically black granules and are added directly to the mixing tanks of the asphalt mixing plant during the asphalt mixture production process.
[0003] Currently, the addition of anti-rutting agents is mostly done manually. Manually weighing the asphalt is not only inefficient but also labor-intensive. During the addition of anti-rutting agents, the high temperature, dust, and strong odors near the asphalt mixing tank can negatively impact the health of workers. The speed of manual addition is difficult to control; if too much anti-rutting agent is poured in at once, material can accumulate in some areas, causing the agent to melt and clump together, affecting the asphalt mixing effect and requiring more time for equipment to achieve uniform mixing, thus reducing the efficiency of asphalt processing.

[0024] A flow guide block 10 is fixedly connected to the center of the bottom of the weighing cylinder 2. A mounting plate 11 is fixedly connected to the bottom of the flow guide block 10. A fixing plate 12 is slidably connected inside the mounting plate 11. A weighing sensor 13 is fixedly connected to the top of the fixing plate 12. The top load-bearing pressure plate of the weighing sensor 13 is fixedly connected to the mounting plate 11. The fixing plate 12 is fixedly connected inside the housing 1. The weighing cylinder 2, the baffle 3, and the flow guide block 10 form a weighing box. The weighing sensor 13 weighs the material in the weighing box.
[0025] A guide plate 24 is fixedly connected to the bottom of the inner shell 1. The first spiral conveying rod 14 is adapted to the guide plate 24. A second motor 15 is fixedly connected to one side of the shell 1. The output end of the second motor 15 is fixedly connected to the first spiral conveying rod 14.
[0026] A transmission pipe 16 is provided on one side of the housing 1, and a feeding port is provided on the top side of the transmission pipe 16. A second spiral conveying rod 17 is rotatably installed inside the transmission pipe 16. A third motor 18 is fixedly connected to the bottom end of the transmission pipe 16, and the output end of the third motor 18 is fixedly connected to the second spiral conveying rod 17.
[0027] A discharge pipe corresponding to the position of the first spiral conveyor rod 14 is fixedly connected to one side of the housing 1. One end of the first spiral conveyor rod 14 passes through the housing 1 and is rotatably connected to the discharge pipe. The bottom of the discharge pipe is fixedly connected to the transmission pipe 16. The discharged material is uniformly conveyed to the top feeding port of the transmission pipe 16 through the first spiral conveyor rod 14 and the second spiral conveyor rod 17 to complete the feeding.
[0028] Two fixed rods 20 are fixedly connected to the bottom of the storage funnel 19. A feeding motor 21 is fixedly connected between the two fixed rods 20. A guide cone 22 is fixedly connected to the top of the feeding motor 21. A third spiral conveying rod 23 is fixedly connected to the top of the guide cone 22. The third spiral conveying rod 23 is adapted to the storage funnel 19. During operation, the feeding motor 21 drives the third spiral conveying rod 23 to rotate, which quickly transports the material inside the storage funnel 19 into the weighing box for weighing. The required material is weighed without manual weighing, which improves the weighing efficiency.
[0029] In use, this utility model works as follows: Anti-rutting agent is poured into the storage funnel 19 via a transport device. The weighing cylinder 2, guide block 10, and four baffles 3 form a weighing box. When asphalt needs additional material, the feeding motor 21 operates, driving the guide cone 22 and the third spiral conveying rod 23 to rotate, transporting the material inside the storage funnel 19 into the weighing box. Then, the weighing sensor 13 weighs the material in the weighing box at the top of the weighing sensor 13. When the anti-rutting agent inside the weighing box reaches the required weight, the feeding motor 21 stops working. Then, the first motor 4 operates, driving the threaded rod 5 to rotate. The threaded rod 5 drives the slider 6 to move upwards. At this time, the slider 6 pulls the second connecting rod 8 towards the slider 6 via the first connecting rod 7. The second connecting rod 8 is hinged to the pull rod 9. The second connecting rod 8 then pulls the pull rod 9 to rotate the shaft 25. The rotating shaft 25 rotates, causing the baffle 3 to rotate and tilt, thus pouring the material at the top of the baffle 3 from the bottom of the weighing cylinder 2 to the top of the guide plate 24. After the material is poured out, the first motor 4 drives the threaded rod 5 to reverse. At this time, the slider 6 descends and pushes the second connecting rod 8 through the first connecting rod 7. The second connecting rod 8 drives the pull rod 9 to swing back to its original position. The four baffles 3 are in pairs. The four baffles 3 rotate so that the two sides of each group of baffles 3 are respectively in contact with the inner wall of the weighing cylinder 2 and one side of the guide block 10. The two baffles 3 in each group are in contact with each other. The bottom of the weighing cylinder 2 is sealed by the four baffles 3 to prevent the anti-rutting agent particles from leaking out during weighing. The material is weighed and discharged quickly through the weighing box, achieving the goal of eliminating the need for manual weighing, improving efficiency, and making the operation simple, convenient, time-saving and labor-saving.
[0030] When the device is in use, the top of the transmission pipe 16 can be fixed to one side of the asphalt mixing device. The material falling into the guide plate 24 falls along the inclined surface of the guide plate 24 to the periphery of the first spiral conveyor 14. The second motor 15 drives the first spiral conveyor 14 to rotate, feeding the material into the transmission pipe 16 at a uniform speed. At the same time, the third motor 18 drives the second spiral conveyor 17 to rotate, conveying the material to the feeding port at the top of the transmission pipe 16, thus completing the addition of the anti-rutting agent. By controlling the speed of the second motor 15 and the third motor 18, the anti-rutting agent can be added to the asphalt being mixed at a uniform speed, preventing the anti-rutting agent from being added too quickly and affecting the processing quality and mixing efficiency of the asphalt.
