[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a recycling device for regenerating asphalt pavement surface layer waste includes a processing box 1. A motor 2 is fixedly connected to the upper end of the processing box 1. An output shaft is fixedly connected to the end of the motor 2 near the processing box 1. A rotating rod is fixedly connected to the end of the output shaft away from the motor 2. The rotating rod extends through the processing box 1 and into the interior of the processing box 1. A drum screen 16 is fixedly connected to the end of the rotating rod away from the output shaft. A column 17 is fixedly connected to the surface of the drum screen 16. A separating plate 18 is fixedly connected to the end of the column 17 away from the drum screen 16.

[0022] The processing box 1 has a fixed connection to a recycling cylinder 12, and two drum screens 16 are located inside the recycling cylinder 12. The two drum screens 16 are arranged symmetrically about the center of the recycling cylinder 12. A fixing block 19 is fixedly connected to the surface of the drum screen 16. A second separation plate 20 is fixedly connected to the end of the fixing block 19 away from the drum screen 16. The separation plate 18 is located above the second separation plate 20. By starting the motor 2, the motor 2 will drive the rotating rod on the front of the output shaft to rotate, thereby driving the drum screen 16 below to rotate together. When the separation plates 18 on the surface of the drum screen 16 come into contact with each other, the separation of asphalt waste can be completed, so that it can continue to be conveyed downward through the second filter plate 13, and finally pass through the second separation plate 20 below the drum screen 16 to complete the final separation.

[0023] The upper end of the processing box 1 is fixedly connected to the feeding port 3, the upper end of the processing box 1 is fixedly connected to the docking plate 5, the upper end of the docking plate 5 is fixedly connected to the cylinder 4, and the number of docking plates 5 is set to two, with the two docking plates 5 arranged symmetrically about the center of the cylinder 4.

[0024] The upper end of the docking plate 5 is fixedly connected to an accompanying rod 6, which passes through the docking plate 5. The lower end of the cylinder 4 is fixedly connected to a pressing rod 7. The end of the pressing rod 7 away from the cylinder 4 is fixedly connected to a connecting block 8. The end of the connecting block 8 away from the pressing rod 7 is fixedly connected to a pressing plate 9, which contacts the inner wall of the recycling cylinder 12.

[0025] The inner wall of the recycling cylinder 12 is fixedly connected to a filter plate 10, and the surface of the filter plate 10 is provided with several sieve holes 11. The inner wall of the recycling cylinder 12 is fixedly connected to a second filter plate 13, and the surface of the second filter plate 13 is fixedly connected to a fixing plate 14. The surface of the fixing plate 14 is rotatably connected to a rotating bolt 15. The second filter plate 13 is located below the filter plate 10. The drum screen 16 rotates through the second filter plate 13. The asphalt waste to be recycled is added into the processing box 1 through the feeding port 3. The asphalt waste will fall onto the filter plate 10 set inside the recycling cylinder 12 first. At this time, the cylinder 4 is activated. The cylinder 4 will drive the accompanying rod 6 on the docking plate 5 to move up and down, thereby causing the extrusion rod 7 below the cylinder 4 to move. The extrusion rod 7 will also drive the extrusion plate 9 below the connecting block 8 to move closer to the filter plate 10. When the extrusion plate 9 contacts the filter plate 10, under the action of the cylinder 4, it can separate the coarse sand and impurities in the waste from the asphalt mixture. This can improve the purity of the recycled asphalt and ensure the efficiency of subsequent processes.

[0026] The inner wall of the recycling cylinder 12 is fixedly connected to a vertical block 23. An electric telescopic rod 24 is fixedly connected to the end of the vertical block 23 away from the recycling cylinder 12. A recycling shovel 25 is fixedly connected to the end of the electric telescopic rod 24 away from the vertical block 23.

[0027] The surface of the recycling cylinder 12 is provided with a lever 21, and a heating box 22 is fixedly connected inside the processing box 1. The lever 21 is located in front of the heating box 22. An opening plate is provided on the surface of the processing box 1, located in front of the heating box 22. By activating the electric telescopic rod 24, the electric telescopic rod 24 will push the recycling shovel 25 in front, so that the waste will pass through the lever 21 in front of the recycling cylinder 12 and finally enter the interior of the heating box 22. This can soften the original asphalt, making it easier to reprocess. Finally, the recycled asphalt waste can be obtained through the opening plate, thereby reducing the demand for new materials and saving natural resources.

[0028] This utility model provides a recycling device for regenerating waste materials from the surface layer of asphalt pavement. The specific working principle is as follows:

[0029] During use, the user needs to add the asphalt waste to be recycled into the processing tank 1 through the feeding port 3. The asphalt waste will then preferentially fall onto the filter plate 10 inside the recycling cylinder 12. At this time, the cylinder 4 is activated, causing the accompanying rod 6 on the connecting plate 5 to move up and down reciprocally. This causes the extrusion rod 7 below the cylinder 4 to simultaneously move the extrusion plate 9 below the connecting block 8 closer to the filter plate 10. When the extrusion plate 9 contacts the filter plate 10, under the action of the cylinder 4, it can separate the coarse sand and impurities in the waste from the asphalt mixture. This improves the purity of the recycled asphalt and ensures the efficiency of subsequent processes. The qualified waste that has completed the above steps will continue to fall through the sieve holes 11 on the surface of the filter plate 10 onto the second filter plate 13 below. When motor 2 is started, it drives the rotating rod on the front of the output shaft to rotate, which in turn drives the drum screen 16 below to rotate. When the separation plates 18 on the surface of the drum screen 16 come into contact with each other, the asphalt waste can be separated, allowing it to continue to be conveyed downwards through the second filter plate 13. Finally, it passes through the second separation plate 20 below the drum screen 16 to complete the final separation. At this time, the electric telescopic rod 24 is started, which pushes the recycling shovel 25 on the front, so that the waste will pass through the actuating plate 21 on the front of the recycling cylinder 12 and finally enter the interior of the heating box 22. This softens the original asphalt, making it easier to reprocess. Finally, the recycled asphalt waste can be obtained by opening the plate, thereby reducing the need for new materials and saving natural resources.
