Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of asphalt transmission devices, specifically to a transmission device for asphalt mixtures. Background Technology
[0002] Asphalt mixture is a composite material mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder.
[0003] A Chinese patent application (CN202323116177.1) discloses a material conveying device for asphalt material production. It describes: "A mounting base has four supporting vertical plates fixedly connected to its upper surface. Two of the supporting vertical plates along the length direction are jointly fixedly connected to a mounting horizontal plate. Multiple transmission rollers are rotatably connected between opposite sides of the two mounting horizontal plates. A transmission belt is connected between the multiple transmission rollers. Rubber baffles are fixedly connected to both sides of the transmission belt. When a second servo motor is activated, its output shaft rotates the rotating disk, causing the pulling rod to pull the moving rod back and forth. This causes the fixed plate to move back and forth with multiple tamping rods, thereby tamping the material on the transmission belt evenly, which is beneficial for subsequent material transport."
[0004] The existing technologies described above facilitate the transport of asphalt mixtures, but in our simulations, we found that these technologies still have certain shortcomings:
[0005] On the one hand, since the stirring rod is set on one side of the device, the asphalt mixture needs to be transported a certain distance before it can be stirred by the stirring rod. Before that, the asphalt mixture cannot be stirred. It may be that the asphalt mixture sticks together or even gradually solidifies during the transportation process, which may lead to an unsatisfactory stirring and dispersing effect on the asphalt mixture, thus affecting the final quality of the asphalt mixture.
[0006] On the other hand, rinsing the conveyor belt by spraying water will cause wastewater to splash everywhere, affecting the cleanliness of the equipment. At the same time, since the residual materials adhering to the conveyor belt can be recycled, spraying water will cause the residual materials to mix with water, making them difficult to reuse and resulting in waste of residual materials. Even if dry and wet separation can be achieved, it will consume more manpower and resources, resulting in low economic efficiency. Utility Model Content
[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for asphalt mixture, comprising multiple supporting columns and a support frame; the support frame is installed on the top of the multiple supporting columns, and a conveyor belt driven by a servo motor is installed on the inner side of the support frame; a cover plate is fixed to the top of the support frame by bolts, and multiple sets of dispersing rods are fixed at equal intervals at the bottom of the cover plate; a set of heating rods is installed at the bottom of the cover plate and between every two sets of dispersing rods; a fixing frame is fixed at the bottom of the support frame and near the discharge port of the conveyor belt, a scraper is fixed to the left side inside the fixing frame, and a waste collection frame is provided at the bottom of the fixing frame.
[0009] As a further embodiment of this utility model: the servo motor is installed on one side of the support frame and near the feed inlet of the conveyor belt. A drive roller for driving the conveyor belt is connected to the power output shaft of the servo motor. Rubber baffles are integrally formed on both sides of the conveyor belt.
[0010] As a further embodiment of this utility model: an opening is provided on one side of the top of the cover plate, a feeding hopper is fixed at the top of the opening, and a discharge plate is fixed at the bottom of the support frame and at the position of the conveyor belt discharge port.
[0011] As a further embodiment of this utility model: each group of dispersing rods includes four longitudinally arranged rods forming three gaps, and each group of heating rods includes three longitudinally arranged rods, with the three rods of each group of heating rods corresponding to the three gaps of each group of dispersing rods.
[0012] As a further embodiment of this utility model: the bottom of the dispersing rod and the bottom of the heating rod are slidably attached to the top of the conveyor belt, and the heating rod is connected to the mains power through a wire.
[0013] As a further embodiment of this utility model: the top and bottom of the fixed frame are connected, the bottom of the fixed frame is connected to the waste collection frame, the scraper is set at an inclination, the top of the scraper is attached to the bottom of the conveyor belt, and the longitudinal length of the scraper is adapted to the width of the conveyor belt.
[0014] As a further embodiment of this utility model: a bearing plate is fixed to the inner side of the supporting column, and limit sliders are fixed to both sides of the bottom of the waste collection frame. The waste collection frame is slidably connected to the top of the bearing plate and located at the bottom of the fixed frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. In this application, by setting a cover plate on the conveyor belt and setting a dispersing rod and a heating rod under the cover plate, the dispersing rod and the heating rod are staggered to effectively disperse the material evenly in various areas. They are also closer to the feeding area, which can disperse the material evenly more quickly. Multiple sets of dispersing rods and heating rods can continuously disperse the material evenly until the material is discharged. In cold weather, the heating rods can also maintain the temperature of the material, reducing the possibility of the material sticking together or even gradually solidifying due to cooling, thus ensuring the final quality of the asphalt mixture.
[0017] Second, in this application, by setting a fixed frame, scraper and waste collection frame at the bottom of the conveyor belt, the residual material adhering to the conveyor belt can be scraped off by the scraping action of the scraper and fall directly into the waste collection frame. This method can realize the direct collection of residual material and subsequent direct recycling, which is more convenient and more economical than the existing technology.

[0024] 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.
[0025] Please see Figure 1-4A conveying device for asphalt mixture includes multiple support columns 1 and a support frame 2. The support frame 2 is installed on top of the multiple support columns 1. A conveyor belt 4 driven by a servo motor 3 is installed on the inner side of the support frame 2. There are four support columns 1 for supporting and fixing the support frame 2 to ensure the stability of the support frame 2. A cover plate 5 is fixed to the top of the support frame 2 by bolts. Multiple sets of dispersing rods 13 are fixed at equal intervals at the bottom of the cover plate 5. A set of heating rods 14 is installed at the bottom of the cover plate 5 between every two sets of dispersing rods 13. The cover plate 5 is fixed by bolts and can be disassembled later to clean the dispersing rods 13 and maintain the heating rods 14. Another function of the cover plate 5 is to partially seal the top of the support frame 2, which can effectively reduce the heat dissipation of the material and further ensure the temperature of the material. A fixing frame 9 is fixed at the bottom of the support frame 2 near the discharge port of the conveyor belt 4. A scraper 901 is fixed on the left side inside the fixing frame 9. A waste collection frame 11 is provided at the bottom of the fixing frame 9.
[0026] Please see Figure 1 In this embodiment, the servo motor 3 is installed on one side of the support frame 2 and near the feed inlet of the conveyor belt 4. The power output shaft of the servo motor 3 is connected to a drive roller for driving the conveyor belt 4. Both sides of the conveyor belt 4 are integrally formed with rubber baffles 401.
[0027] Specifically, after the servo motor 3 is started, it can drive the drive roller to rotate. The rotation of the drive roller can drive the conveyor belt 4 to move. The rubber baffles 401 on both sides of the conveyor belt 4 form a blocking structure on both sides of the conveyor belt 4 to prevent materials from falling from both sides of the conveyor belt 4.
[0028] Please see Figure 1 In this embodiment, an opening 6 is provided on the top side of the cover plate 5, a feeding hopper 7 is fixed at the top of the opening 6, and a discharge plate 8 is fixed at the bottom of the support frame 2 and at the discharge port of the conveyor belt 4.
[0029] Specifically, the feed hopper 7 introduces the material and ensures that the material falls evenly onto the conveyor belt 4, while the discharge plate 8 guides the output material away for convenient subsequent use.
[0030] Please see Figure 3 and Figure 4 In this embodiment, each set of dispersing rods 13 includes four longitudinally arranged rods and forms three gaps. Each set of heating rods 14 includes three longitudinally arranged rods, and the three rods of each set of heating rods 14 correspond to the three gaps of each set of dispersing rods 13. The bottom of the dispersing rods 13 and the bottom of the heating rods 14 are slidably attached to the top of the conveyor belt 4. The heating rods 14 are connected to the mains power through wires.
[0031] Specifically, the multiple sets of dispersing rods 13 and multiple sets of heating rods 14 can achieve continuous dispersion of materials. The staggered arrangement of the dispersing rods 13 and heating rods 14 can change the material's travel path and better disperse the material. The bottom of the dispersing rods 13 and the bottom of the heating rods 14 are in contact with the conveyor belt 4, which can better disperse the material and prevent material from being missed.
[0032] Please see Figure 2 and Figure 4 In this embodiment, the top and bottom of the fixed frame 9 are connected, and the bottom of the fixed frame 9 is connected to the waste collection frame 11. The scraper 901 is set at an angle, and the top of the scraper 901 is attached to the bottom of the conveyor belt 4. The longitudinal length of the scraper 901 is adapted to the width of the conveyor belt 4 to ensure the integrity of the scraping area. The inner side of the support column 1 is fixed with a bearing plate 10, and the bottom sides of the waste collection frame 11 are fixed with limit sliders 12. The waste collection frame 11 is slidably connected to the top of the bearing plate 10 and located at the bottom of the fixed frame 9.
[0033] Specifically, after the scraper 901 scrapes off the residual material on the conveyor belt 4, it can fall directly into the waste collection box 11 through the enclosure limit of the fixed frame 9. The waste collection box 11 is slidably connected to the support plate 10, which makes it convenient to remove the waste collection box 11 from the support plate 10 and recycle the material temporarily stored in the waste collection box 11.
[0034] In use: The asphalt mixture falls onto the conveyor belt 4 through the feed hopper 7. When it is transported by the conveyor belt 4, the asphalt mixture first passes through the dispersing rod 13 and is dispersed by the dispersing rod 13. Then it passes through the heating rod 14. Since the heating rod 14 and the dispersing rod 13 are staggered, the asphalt mixture can be dispersed by the heating rod 14 again. After that, it continues to be dispersed by the subsequent dispersing rod 13 and heating rod 14, thereby achieving uniform dispersion of the asphalt mixture during transportation and reducing the mutual adhesion or even gradual solidification of the asphalt mixture during transportation.
[0035] When the asphalt mixture reaches the end point, it will fall onto the discharge plate 8 and be discharged by the guide of the discharge plate 8, which is convenient for subsequent use or to enter the next stage. When there is residual material on the conveyor belt 4, due to the continuous movement of the conveyor belt 4, it will pass through the scraper 901. Since the scraper 901 is always in contact with the conveyor belt 4, the residual material on the conveyor belt 4 can be directly scraped off by the scraping action of the scraper 901. The scraped material falls into the waste collection box 11 through the fixed frame 9 for temporary storage, which is convenient for subsequent direct recycling.
[0036] When the weather is cold, increasing the probability of the asphalt mixture sticking together or even gradually solidifying, workers can turn on the heating rod 14 to heat the material and maintain the temperature of the asphalt mixture, thereby reducing the probability of the asphalt mixture sticking together or even gradually solidifying.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
