Description

Technical Field

[0001] This utility model relates to the field of asphalt transfer and insulation vehicles, and in particular to an asphalt mixture anti-segregation transfer and insulation vehicle. Background Technology

[0002] In modern highway construction, with the rapid development of expressway construction, the quality requirements for asphalt pavement construction are becoming increasingly stringent. During the construction of asphalt concrete pavement, temperature control of the asphalt mixture is one of the key aspects to ensure construction quality. Strict temperature control is necessary in all stages of asphalt mixture preparation, transportation, paving, and compaction to ensure the stability of its physical and chemical properties, thereby achieving the desired construction results.

[0003] However, in the traditional transportation of asphalt mixtures, conventional transport vehicles are mostly ordinary dump trucks. During long-distance transportation, due to vehicle bumps and vibrations, aggregates of different particle sizes will segregate due to differences in settling velocity. Coarse aggregates tend to accumulate at the bottom or edges, while fine aggregates are unevenly distributed, which in turn affects the paving quality. To address this issue, an anti-segregation transport and insulation vehicle for asphalt mixtures is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an asphalt mixture anti-segregation transfer and insulation vehicle, which aims to improve the problem in the prior art that "when transported by traditional transport vehicles, the asphalt mixture will segregate due to driving vibration, thereby reducing the quality of road paving".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an asphalt mixture anti-segregation transfer and insulation vehicle, comprising a vehicle body, an insulated storage box at the top of the vehicle body, an anti-segregation component inside the insulated storage box, the anti-segregation component including a drive motor, the drive motor being fixedly installed on the right side of the insulated storage box, a drive rod being fixedly connected to the left side of the output shaft of the drive motor, and a rotating sleeve being fixedly connected to the left side of the drive rod, the rotating sleeve being provided in two sets, and the two sets of rotating sleeves being rotatably connected to the left and right inner walls of the insulated storage box respectively. A screw conveyor is fixedly connected at the center between the two sets of rotating sleeves. A second gear is rotatably connected to the outer wall of the drive rod, and the second gear is fixedly connected to the inner right wall of the insulated storage box and located inside the right side of the rotating sleeve. Driven rods are arranged on the upper and lower sides of the drive rod, and the two ends of the driven rods are rotatably connected to the corresponding rotating sleeves. A first gear is meshed on the upper and lower ends of the second gear, and both sets of first gears are rotatably connected to the inner right wall of the rotating sleeve and fixed to the corresponding driven rods. A screw conveyor is fixed to both the drive rod and the driven rod.

[0007] The insulated storage box is equipped with a cleaning component for cleaning the inner wall of the insulated storage box.

[0008] As a further description of the above technical solution:

[0009] The cleaning assembly includes a scraper, a servo motor fixedly installed on the right side of the insulated storage box above the drive motor, and a connecting assembly connecting the servo motor and the scraper. The scraper has a clearance hole in the middle for avoiding the anti-segregation assembly. The servo motor drives the connecting assembly to work, so that the scraper moves along the axial direction of the anti-segregation assembly.

[0010] As a further description of the above technical solution:

[0011] The connecting assembly includes a servo motor, the left output shaft of which is connected to a threaded rod. The threaded rod passes through the insulated storage box and is rotatably connected thereto. The top of the scraper is threadedly engaged with the threaded rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, a drive motor is set to drive the rotating sleeve and two sets of gears to rotate. Since the gears are fixed, the two sets of gears that mesh with each other can rotate while rotating, thereby causing multiple sets of augers to rotate while rotating, stirring and turning the asphalt mixture in the heat-insulated storage box. The rotation of multiple sets of augers and their rotation increase the stirring effect, thereby reducing the segregation of aggregates caused by vibration and bumps during transportation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an asphalt mixture anti-segregation transport and insulation vehicle, comprising a vehicle body 1, with an insulated storage box 4 at the top of the vehicle body 1 for storing and transporting asphalt. The inner wall of the insulated storage box 4 is made of insulation material to keep the asphalt mixture inside the storage box 4 warm and reduce the rate of temperature drop. An anti-segregation component is provided inside the insulated storage box 4, including a drive motor 2 that drives a drive rod 24 to rotate. The drive motor 2 is fixedly installed on the right side of the insulated storage box 4, and the output shaft of the drive motor 2 is on the left side. A drive rod 24 is fixedly connected to the side to drive the rotating sleeve 21 to rotate. A rotating sleeve 21 that protects gear one 23 and gear two 25 is fixedly connected to the left side of the drive rod 24. Two sets of rotating sleeves 21 are provided, and the two sets of rotating sleeves 21 are rotatably connected to the inner walls of the left and right sides of the heat preservation storage box 4, respectively. An auger 22 is fixedly connected at the center between the two sets of rotating sleeves 21. A gear two 25 that meshes with the two sets of gear one 23, causing the two sets of gear one 23 to rotate while rotating, thereby driving the other two sets of augers 22 to rotate while rotating itself.

[0027] Furthermore, gear 25 is fixedly connected to the inner right side of the insulated storage box 4 and located inside the inner right side of the rotating sleeve 21. Driven rods are arranged on the upper and lower sides of the drive rod 24, and the two ends of the driven rods are rotatably connected to their corresponding rotating sleeves 21. Gear 23, which drives one set of augers 22 to rotate and stir, is meshed with the upper and lower ends of gear 25. Both sets of gear 23 are rotatably connected to the inner right side of the rotating sleeve 21 and fixed to their corresponding driven rods. Augers 22 are fixed on both the drive rod 24 and the driven rods. Setting multiple sets of augers 22 can improve the stirring effect. At the same time, the two sets of gear 23, together with gear 25, can make multiple sets of augers 22 rotate and flip, improve the mixing effect, and further improve the anti-segregation effect and mixing quality.

[0028] Reference Figure 1 , Figure 2 and Figure 3The interior of the insulated storage box 4 is equipped with a cleaning assembly for cleaning the inner wall of the insulated storage box 4, which facilitates cleaning of the inner wall of the insulated storage box 4. The cleaning assembly includes a scraper 31 that can scrape off the asphalt mixture adhering to the inner wall of the insulated storage box 4, a servo motor 3 fixedly installed on the right side of the insulated storage box 4 above the drive motor 2, which drives the threaded rod 32 to rotate, and a connecting assembly connecting the servo motor 3 and the scraper 31. The scraper 31 has a clearance hole in the middle for avoiding the anti-segregation assembly. The clearance hole provides space for multiple sets of screw conveyors 22 to rotate. The servo motor 3 drives the connecting assembly to work, so that the scraper 31 moves along the axial direction of the anti-segregation assembly. The connecting assembly includes the servo motor 3. The left output shaft of the servo motor 3 is connected to the threaded rod 32 that drives the scraper 31 to move. The threaded rod 32 passes through the interior of the insulated storage box 4 and is rotatably connected to it. The top of the scraper 31 is threadedly fitted with the threaded rod 32. The left output shaft of the servo motor 3 is fixedly connected to a threaded rod 32 that drives the scraper 31 to move. The threaded rod 32 passes through the right side of the heat-insulating storage box 4 and is rotatably connected to the inner wall of the heat-insulating storage box 4. The scraper 31 passes through and is threadedly connected to the outer wall of the threaded rod 32. The middle part of the scraper 31 is provided with a clearance hole to provide space for the rotation of multiple sets of augers 22. The front surface of the scraper 31 is fixedly connected to a positioning block 34 that provides support for the scraper 31 by matching the positioning groove 33. The upper end of the inner wall of the front surface of the heat-insulating storage box 4 is provided with a positioning groove 33 that matches the positioning block 34. The positioning block 34 is slidably connected to the inner wall of the positioning groove 33. The positioning block 34 and the positioning groove 33 can make the scraper 31 move stably. The bottom ends of the positioning block 34 and the positioning groove 33 are both set as inclined surfaces. By setting them as inclined surfaces, the asphalt mixture entering the inner wall of the positioning groove 33 can slide out along the inclined surface to prevent jamming.

[0029] Working principle: During use, the vehicle body 1 carries the insulated storage box 4 to transport asphalt mixture. Since the inner wall of the insulated storage box 4 is made of insulation material, it can effectively reduce the impact of the external environment on the temperature of the asphalt mixture inside the box. During transportation, the temperature of the asphalt mixture is maintained as much as possible to ensure its stability and provide a good foundation for subsequent construction.

[0030] When it is necessary to stir the asphalt mixture in the insulated storage tank 4 to prevent segregation, the drive motor 2 is started. The drive motor 2, as the power source, drives the drive rod 24 to rotate through its output shaft. When the drive rod 24 rotates, it drives the rotating sleeve 21, which is fixedly connected to it, to rotate as well. The auger 22 fixed on the left side of the middle of the rotating sleeve 21 and the other two sets of augers 22 at the upper and lower ends also rotate, starting to stir the asphalt mixture in the insulated storage tank 4. At the same time as the drive rod 24, the rotating sleeve 21, and the first gear 23 rotate, the second gear 25 is fixed on the insulated storage tank 4 and meshes with the two sets of first gears 23. This causes the two sets of first gears 23 to rotate and mesh with the second gear 25, and then rotate on their own. Since the two sets of gears 23 are respectively set at the top and bottom of gear 25, and the augers 22 are fixedly connected to their left sides, when the two sets of gears 23 rotate, the other two sets of augers 22 will also rotate and rotate on their own axis. By cooperating with gear 25, the two sets of gears 23 can rotate and rotate on their own axis at the same time to tumble the asphalt. The augers 22 form a complex mixing flow field in the heat-insulated storage tank 4, which tumbles and mixes the asphalt mixture in an all-round and more efficient manner, so that the coarse aggregate and fine aggregate are fully mixed, effectively avoiding segregation caused by vehicle bumps and driving vibrations, greatly improving the mixing effect, and further improving the anti-segregation effect and mixing quality.

[0031] After the asphalt mixture is transported to its destination and unloaded, the servo motor 3 is started. The left output shaft of the servo motor 3 drives the threaded rod 32 to rotate. Since the scraper 31 is threadedly connected to the outer wall of the threaded rod 32, and the positioning block 34 fixedly connected to the front surface of the scraper 31 is slidably connected to the positioning groove 33 opened at the upper end of the inner wall of the front surface of the heat-insulated storage box 4, when the threaded rod 32 rotates, the scraper 31 will move along the axial direction of the threaded rod 32 on the inner wall of the heat-insulated storage box 4. During the movement, the scraper 31 can scrape off the asphalt mixture attached to the inner wall of the heat-insulated storage box 4, thereby cleaning the inner wall of the heat-insulated storage box 4.

[0032] The clearance hole in the middle of the scraper 31 provides rotation space for multiple sets of augers 22, ensuring that the augers 22 are not obstructed by the scraper 31 during the cleaning process. The inclined surface at the bottom of the positioning block 34 and the positioning groove 33 allows the asphalt mixture entering the inner wall of the positioning groove 33 to slide out along the inclined surface, preventing the positioning block 34 and the positioning groove 33 from being stuck by the asphalt mixture, ensuring that the scraper 31 can move stably and complete the cleaning work efficiently, preparing for the next transportation and mixing.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
