Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture filling technology, and in particular to an asphalt mixture filling device. Background Technology

[0002] Asphalt mixture is a composite material made by mixing asphalt, aggregates (such as crushed stone, sand, stone chips, etc.) and possibly added fillers (such as mineral powder) in a certain proportion. It is widely used in paving projects such as roads, airport runways, and parking lots.

[0003] When repairing some asphalt pavements, workers first use tools to clean the corresponding area, and then use appropriate filling devices to fill the area that needs repair with asphalt mixture. However, after filling with asphalt mixture, because the asphalt mixture is relatively loose and contains a large amount of air, these compressed air are like tiny air bladders, which increases the overall porosity of the asphalt mixture. This results in more interconnected, tiny pores and channels inside the subsequently laid pavement, leading to lower overall strength. It also creates conditions for water intrusion and retention, making the pavement prone to loosening under vehicle loads and resulting in poor pavement quality. Utility Model Content

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides an asphalt mixture filling device, such as... Figures 1-3 As shown, the asphalt mixture filling device includes: a placement box 1 for storing asphalt mixture; a filling pipe 2 disposed on the placement box 1 for filling asphalt mixture, wherein a filling mechanism is disposed inside the filling pipe 2; a mounting frame 3 mounted on one side of the placement box 1, wherein an exhaust frame 4 is disposed below the mounting frame 3; and an exhaust mechanism mounted on the mounting frame 3 and the exhaust frame 4, wherein the exhaust mechanism is used to drive the exhaust frame 4 to move up and down to vibrate and exhaust the filled asphalt mixture.

[0018] In this embodiment, workers can move the entire device by pushing it with the handrail on one side of the placement box 1, or connect the entire device to the corresponding mobile device and move the entire device by the mobile device. When performing asphalt mixture filling operations at the corresponding positions, the filling pipe 2 is aligned with the position to be filled, and then the filling mechanism is started by the controller (model SIMATIC S7-1200) on one side of the placement box 1. The filling mechanism fills the asphalt mixture placed in the placement box 1 into the corresponding position. As the placement box 1 moves, continuous filling operations can be performed. During filling, the exhaust mechanism is started by the controller to move the exhaust frame 4 up and down to vibrate and exhaust the filled asphalt mixture, thereby reducing the porosity of the asphalt mixture, improving the strength of the subsequent overall pavement, reducing water intrusion and retention, and thus improving the quality of asphalt mixture pavement.

[0019] In a further preferred embodiment of the present invention, the filling mechanism includes: a first servo motor 5 fixedly installed on the filling tube 2; and a feeding rack 6 rotatably installed inside the filling tube 2, wherein the output shaft of the first servo motor 5 is connected to one end of the feeding rack 6 via a coupling.

[0020] In this embodiment, when asphalt mixture filling is required, the first servo motor 5 is started by the controller. The output shaft of the first servo motor 5 drives the material feeder 6 to rotate inside the filling tube 2 through the coupling. The rotating material feeder 6 enables the asphalt mixture to be filled evenly and stably to the road surface that needs to be repaired, thereby completing the asphalt mixture filling operation.

[0021] In a further preferred embodiment of the present invention, the exhaust mechanism includes: a second servo motor 7 fixedly installed at the bottom of the mounting bracket 3, and a cam 8 for compressing the exhaust bracket 4 is fixedly sleeved on the output shaft of the second servo motor 7; a connecting rod 9 fixedly installed on the mounting bracket 3, and a spring 10 is sleeved on the connecting rod 9; and a connecting frame 11 fixedly installed on the top of the exhaust bracket 4, the connecting frame 11 and the connecting rod 9 being slidably connected, and the connecting frame 11 being used to compress the spring 10.

[0022] In this embodiment, when it is necessary to vent and vibrate the filled asphalt mixture, the controller starts the second servo motor 7. The output shaft of the second servo motor 7 drives the cam 8 to rotate. The special contour of the cam 8 periodically squeezes the venting frame 4, causing the venting frame 4 to move downward to vibrate and vent the asphalt mixture. At the same time, the connecting frame 11 at the top of the venting frame 4 slides downward along the connecting rod 9 and compresses the spring 10. When the cam 8 rotates to a certain position and no longer squeezes the venting frame 4, the compressed spring 10 releases its elastic potential energy, pushing the connecting frame 11 and the venting frame 4 upward to return to the initial position, waiting for the next squeeze from the cam 8. This cycle repeats, realizing the up-and-down vibration action of the venting frame 4 to vibrate and vent the filled asphalt mixture, thereby reducing the porosity of the asphalt mixture, improving the strength of the subsequent overall pavement, reducing water intrusion and retention, and thus improving the quality of asphalt mixture pavement.

[0023] In a further preferred embodiment of this utility model, a moving mechanism is provided on the placement box 1 and the mounting frame 3. The moving mechanism is used to adjust the height of the exhaust rack 4. The moving mechanism includes: a mounting plate 12 fixedly installed on the outer wall of one side of the placement box 1; and an electric telescopic rod 13 fixedly installed on the mounting plate 12. The output shaft of the electric telescopic rod 13 is fixedly connected to the top of the mounting frame 3.

[0024] In this embodiment, when using the exhaust frame 4, the electric telescopic rod 13 is activated by the controller to move the mounting frame 3 according to the actual usage situation, thereby adjusting the usage height of the exhaust frame 4, so as to facilitate the exhaust frame 4 to be inserted into the asphalt mixture for exhaust operation.

[0025] In a further preferred embodiment of the present invention, a stirring mechanism is provided on the placement box 1. The stirring mechanism is used to mix and stir the asphalt mixture in the placement box 1. The stirring mechanism includes: a stirring frame 15 rotatably installed in the placement box 1 for stirring the asphalt mixture; and a third servo motor 14 fixedly installed at the bottom of the placement box 1. The output shaft of the third servo motor 14 is connected to the bottom end of the stirring frame 15 through a coupling.

[0026] In this embodiment, after the asphalt mixture has been stored in the placement box 1 for a period of time, the third servo motor 14 is started by the controller. The output shaft of the third servo motor 14 drives the mixing frame 15 to rotate through the coupling to stir the asphalt mixture in the placement box 1, so that the asphalt, aggregate, filler and other components are fully mixed and uniform, and segregation is avoided.

[0027] In a further preferred embodiment of the present invention, a guide rod 16 is fixedly installed on the mounting bracket 3, and the guide rod 16 and the mounting plate 12 are slidably connected.

[0028] In this embodiment, when the electric telescopic rod 13 moves the mounting frame 3, the mounting frame 3 will cause the guide rod 16 to slide along the mounting plate 12, ensuring that the mounting frame 3 maintains stable vertical movement during the movement, avoiding swaying, deviation, etc., thereby improving the stability of the exhaust frame 4 when it moves.

[0029] In a further preferred embodiment of the present invention, a heating plate 17 is provided on the placement box 1, and the heating plate 17 is used to heat the asphalt mixture in the placement box 1.

[0030] In this embodiment, after the asphalt mixture has been stored in the placement box 1 for a period of time, the heating plate 17 is activated by the Eurotherm 3504 thermostat installed on the placement box 1 according to actual needs. This can heat the asphalt mixture in the placement box 1, ensuring the fluidity of the asphalt mixture and making it flow more smoothly, thus making the filling process smoother.

[0031] In summary, compared with related technologies, this device can perform filling operations on asphalt mixtures and can vibrate and vent the filled asphalt mixtures, thereby reducing the porosity of the asphalt mixtures, increasing the overall strength of subsequent pavement laying, reducing water intrusion and retention, and thus improving the quality of asphalt mixture pavement laying.
