Description

Technical Field

[0001] This application relates to the field of asphalt mixing equipment, and in particular to an asphalt mixing tower. Background Technology

[0002] Asphalt mixing towers, also known as asphalt mixing plants or asphalt mixture mixing equipment, are large-scale mechanized factory-style complete sets of equipment specifically designed for producing hot-mix asphalt mixtures. Through a series of automated processes, they initially proportion, dry, and heat cold aggregates of different particle sizes, such as crushed stone and sand, and then uniformly mix them with precisely measured hot asphalt and mineral powder at high temperatures, ultimately producing finished asphalt mixtures for road paving. However, in existing asphalt mixing tower equipment, asphalt and fine mineral powder tend to adhere to the inner walls of the mixing container during operation. This requires frequent and intensive manual cleaning, which is inconvenient and can damage the uniformity of the mixture if not cleaned thoroughly. Utility Model Content

[0018] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0019] The following is combined with Figures 1 to 4 The embodiments of this utility model are described below.

[0020] An asphalt mixing tower includes a fixed support tower 100, a feeding device 700, and a shaking and dropping mechanism 800.

[0021] The feeding device 700 is located at the top of the fixed support tower 100, and is used for conveying materials. The shaking mechanism 800 includes a protective housing 810, a drive motor 820, and an eccentric wheel 830. The shaking mechanism 800 is located on one side of the feeding device 700. The drive motor 820 is installed on the inner bottom wall of the protective housing 810. The eccentric wheel 830 is fixed to one end of the output shaft of the drive motor 820. An assembly connecting pad 840 is fixed inside the protective housing 810. A support spring 850 is fixed to the side of the assembly connecting pad 840 near the drive motor 820. A moving plate 860 is connected to one end of the support spring 850. A moving column 870 is fixed to the side of the moving plate 860 away from the eccentric wheel 830.

[0022] Specifically, the bottom of the fixed support tower 100 is fixed with a support leg 200, the top of the fixed support tower 100 is equipped with a mixing container 300, the inside of the mixing container 300 is provided with a mixing mechanism body 400 extending to the outside, the bottom of the support leg 200 is equipped with a mounting plate 500, the top of the mounting plate 500 is fixed with a metal connecting frame 600, the top of the metal connecting frame 600 is equipped with a feeding device 700, and the top of the fixed support tower 100 is provided with a shaking mechanism 800.

[0023] During operation, the feeding device 700 conveys materials such as asphalt powder and mineral powder to the mixing container 300 at the top of the fixed support tower 100. The mixing mechanism body 400 mixes and processes the materials. When it is necessary to clean the material adhering to the inner wall of the mixing container 300, the drive motor 820 of the shaking mechanism 800 is activated. The drive motor 820 drives the eccentric wheel 830 to rotate, and the eccentricity of the eccentric wheel 830 converts the circular motion into the linear reciprocating motion of the moving plate 860. During the rotation of the eccentric wheel 830, it pushes the moving plate 860, causing the moving plate 860 to compress the support spring 850 and drive the moving column 870 to move towards the mixing container 300. One end of the moving column 870 impacts the outer wall of the mixing container 300. The eccentric wheel 830 continues to rotate. When the eccentric wheel 830 moves away from the moving plate 860, the support spring 850 resets and pushes the moving plate 860 and the moving column 870 back to their initial positions, completing one impact cycle. Repeated operation achieves multiple impacts.

[0024] Therefore, by incorporating a shock-drop mechanism 800, one end of the moving column 870 impacts the outer wall of the mixing container 300. Subsequently, a support spring 850 pushes the moving plate 860 back to its original position. This impact shocks away asphalt, mineral powder, and other materials adhering to the inner wall of the mixing container 300, effectively preventing material adhesion, reducing the intensity and frequency of manual cleaning, shortening maintenance time, and improving the equipment's continuous operation capability. It also ensures the cleanliness of the inner wall of the mixing container 300, preventing residual materials from affecting the uniformity of the subsequent asphalt mixture and providing conditions for improving the quality of the finished product.

[0025] Under the intermittent force of the eccentric wheel 830, lateral deviation or tilting is prone to occur. Therefore, in some embodiments, two guide sliders 880 are fixed to the outer side of the moving plate 860, and guide grooves 890 are provided on both inner walls of the protective housing 810. When the drive motor 820 is started and the eccentric wheel 830 pushes the moving plate 860 towards the mixing container 300, the two guide sliders 880 fixed to the outer side of the moving plate 860 slide synchronously along the guide grooves 890 provided on both inner walls of the protective housing 810. When the support spring 850 pushes the moving plate 860 to reset, the guide sliders 880 slide in the opposite direction along the guide grooves 890 with the moving plate 860, thereby restricting the moving plate 860 to only move in a straight line along the direction of the guide grooves 890. This ensures that the movement trajectory of the moving plate 860 is accurate, so that each impact of the moving column 870 can act on the preset position of the mixing container 300, avoiding incomplete cleaning due to impact position deviation, and ensuring uniform cleaning effect in all areas of the inner wall of the mixing container 300.

[0026] In some embodiments, the protective housing 810 is slidably connected to a guide slider 880 via a guide groove 890, and the protective housing 810 is fixedly connected to the fixed support tower 100. Further, a limiting hole is provided inside the assembly connection pad 840, the diameter of which is adapted to the size of the moving column 870.

[0027] Furthermore, one side of the movable plate 860 is fitted against the outer side of the eccentric wheel 830, and the interior of the protective housing 810 has a through hole to accommodate the movement of the movable column 870. Since the protective housing 810 is fixedly connected to the fixed support tower 100, it remains fixed during the operation of the shaking mechanism 800, providing stable support for internal components such as the drive motor 820, eccentric wheel 830, and movable plate 860. During the reciprocating motion of the movable column 870 with the movable plate 860, the diameter of the limiting hole matches the size of the movable column 870, ensuring it always passes through the limiting hole inside the mounting connection pad 840 and moves along the axis of the limiting hole, preventing radial swaying of the movable column 870.

[0028] Therefore, it can ensure the overall stability of the shaking mechanism 800, avoid the displacement of the protective shell 810 causing the impact position of the moving column 870 to shift, ensure that the impact force is effectively transmitted to the mixing container 300, and improve the cleaning effect.

[0029] In some embodiments, a closing mechanism 900 is also installed on the outside of the feeding device 700. The closing mechanism 900 includes a fixed bracket 910, and an assembly connecting frame 920 is fixed to the bottom of the fixed bracket 910. An electric push rod is rotatably connected to the outside of the assembly connecting frame 920 via a rotating shaft. One end of the output shaft of the electric push rod is rotatably connected to a transmission frame via a rotating shaft. A transmission rod is fixed to the outside of the transmission frame, and an installation sleeve is fixed to the outside of the feeding device. Thus, by providing a closing mechanism, after the feeding device has been conveying materials, some residual material may still fall from the discharge port when the conveying stops. At this time, the electric push rod can be activated to make the closing baffle block the discharge port of the feeding device. By blocking the discharge port in time, the spillage of residual material after the conveying stops is effectively prevented.

[0030] In some embodiments, a metal bracket is fixed to the outer side of the transmission rod, and a closing baffle is installed at one end of the metal bracket. Further, the closing baffle is rotatably connected to the feeding device via a rotating shaft, the fixed bracket is fixedly connected to the feeding device, and a discharge port is provided at the bottom of the feeding device. Thus, by connecting the transmission rod and the closing baffle via the metal bracket, the force of the transmission rod can be fully transmitted to the closing baffle. The closing baffle and the feeding device are rotatably connected via a rotating shaft. Using the rotating shaft as a fulcrum, the opening and closing of the closing baffle is achieved by the transmission of the transmission rod, thereby controlling the opening and closing of the discharge port of the feeding device.
