Description

Technical Field

[0001] This utility model relates to the field of metering and batching technology, and in particular to a metering and batching device for highway construction materials. Background Technology

[0002] In highway construction projects, accurate measurement and scientific proportioning of construction materials are crucial for ensuring project quality. As the core equipment ensuring accurate material proportioning, the performance of highway construction material metering and batching devices directly affects the construction quality and service life of the highway. With the continuous expansion of transportation infrastructure construction and the increasing demands for project quality, the development of high-precision, high-stability highway construction material metering and batching devices has become an urgent need in the industry.

[0003] Currently, most common highway construction material metering and batching devices on the market employ traditional mechanical structures, such as relying on gravity flow or simple screw conveyors for material transport and proportioning. These devices typically estimate the amount of material to be fed through fixed-size hoppers or conveying pipes, combined with timers or preset conveying speeds. Their technical principle is to utilize the material's own gravity, causing it to flow out of a storage container under gravity, or to propel the material forward through the rotation of screw blades. The output amount is then controlled based on set time or rotation speed, thereby achieving the initial proportioning of different materials.

[0004] However, the aforementioned existing technologies have a significant problem: it is difficult to accurately control the material proportions. Due to differences in the physical properties of materials, as well as wear and tear on mechanical structures and environmental interference during transportation, relying on gravity flow or simple screw conveying methods cannot accurately control the amount of each material added. This leads to significant fluctuations in the quality of the mixture during actual construction, which in turn affects the strength, durability, and smoothness of the highway, failing to meet the stringent requirements of modern highway construction for high-quality construction materials. Therefore, a highway construction material metering and batching device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a metering and batching device for highway construction materials, which aims to improve the problem that the existing technology cannot accurately control the material ratio, resulting in unstable mixture quality and affecting the strength, durability and smoothness of the highway.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A metering and batching device for highway construction materials includes a support column, a hopper fixedly connected to the top of the support column, a first hollow column fixedly connected to the bottom of the hopper, a driving assembly provided on the side wall of the first hollow column, a hollow plate fixedly connected to one end of the first hollow column, a diagonal brace fixedly connected to the side wall of the hollow plate, a connecting block fixedly connected to the top of the diagonal brace, a hydraulic cylinder rotatably connected to the side wall of the connecting block, a rotating shaft fixedly connected to the output end of the hydraulic cylinder, a rotating plate rotatably connected to the side wall of the rotating shaft, and a support assembly provided on the inner wall of the hollow plate.

[0008] The support assembly includes a support plate, the side wall of which is fixedly connected to the inside of a hollow plate. A rotating block is rotatably connected to the inner wall of the support plate. The side wall of the rotating block is fixedly connected to the side wall of the rotating plate.

[0011] As a further description of the above technical solution:

[0012] A mixing tank is fixedly connected to the bottom of the hollow plate, a second motor is fixedly connected to the side wall of the mixing tank, and a synchronous shaft is fixedly connected to the output end of the second motor.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the synchronous shaft is fixedly connected to a stirring blade, and the outer wall of the stirring blade is rotatably connected to the inside of the mixing tank.

[0015] As a further description of the above technical solution:

[0016] A discharge plate is fixedly connected to the side wall of the mixing tank, and a second hollow column is fixedly connected to the outer wall of the synchronous shaft.

[0017] As a further description of the above technical solution:

[0018] A limiting ring is fixedly connected to the inner wall of the second hollow column, and a sliding column is slidably connected to the inner wall of the limiting ring. A scraper is fixedly connected to one end of the sliding column.

[0022] A spring is provided on the outer wall of the sliding column. One end of the spring is fixedly connected to the outer wall of the sliding column, and the other end of the spring is fixedly connected to the side wall of the limiting ring.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a hydraulic cylinder drives a rotating shaft to move, which in turn drives a rotating plate to rotate. The rotating plate is then limited by a support plate and a rotating block. Subsequently, the rotating plate is subjected to force, which drives the connecting column and the sealing column to rotate. This causes the side wall of the sealing column to rotate at one end of the first hollow column, achieving the effect of quantitative material dispensing. This solves the problem of inaccurate material proportion control, which leads to unstable mixture quality and affects the strength, durability and smoothness of the highway. It also improves the stability of the highway construction material metering and batching device.

[0025] 2. In this utility model, the rotation of the synchronous shaft drives the second hollow column to rotate, and the second hollow column drives the internal sliding column and scraper to rotate inside the mixing tank. At the same time, the spring provides the scraper with a rebound force, which achieves the effect of cleaning the inside of the mixing tank. This solves the problem that if the inside of the mixing tank is not cleaned, the residual old material will mix with the new batch of material, resulting in inaccurate proportions and affecting the performance of the mixture. This improves the practicality of the metering and batching device for highway construction materials. Attached Figure Description

[0036] Reference Figures 1-4 This utility model provides an embodiment of a highway construction material metering and batching device, including a support column 2 for fixing a hopper 1 and providing structural stability. The hopper 1 is fixedly connected to the top of the support column 2, and a first hollow column 3 is fixedly connected to the bottom of the hopper 1. A driving assembly is provided on the side wall of the first hollow column 3. A first motor 7 drives a screw rod 6 to rotate, pushing the material falling from the hopper 1 towards the hollow plate 4. This achieves automatic material conveying, avoids manual intervention, and improves batching efficiency. A hollow plate 4 is fixedly connected to the end of the hollow plate 4. A diagonal brace 8 is fixedly connected to the side wall of the hollow plate 4. A connecting block 9 is fixedly connected to the top of the diagonal brace 8. A hydraulic cylinder 10 is rotatably connected to the side wall of the connecting block 9. The hydraulic cylinder 10 pushes the rotating plate 12 through the rotating shaft 11, which drives the sealing column 16 to rotate. The sealing column 16 controls the material flow by adjusting the opening and closing degree of the discharge port of the first hollow column 3. A rotating shaft 11 is fixedly connected to the output end of the hydraulic cylinder 10. A rotating plate 12 is rotatably connected to the side wall of the rotating shaft 11. A support assembly is provided on the inner wall of the hollow plate 4.

[0037] The support assembly includes a support plate 13, the side wall of which is fixedly connected to the inside of the hollow plate 4.

[0038] Reference Figures 5-7 A mixing tank 5 is fixedly connected to the bottom of a hollow plate 4. A second motor 17 is fixedly connected to the side wall of the mixing tank 5. The second motor 17 is a standard industrial motor, such as a Y-series three-phase asynchronous motor, with power configured according to load requirements. This is existing technology. A synchronous shaft 18 is fixedly connected to the output end of the second motor 17. A stirring blade 19 is fixedly connected to the outer wall of the synchronous shaft 18. The outer wall of the stirring blade 19 is rotatably connected to the inside of the mixing tank 5. A discharge plate 20 is fixedly connected to the side wall of the mixing tank 5. After mixing, the discharge plate 20 is opened to discharge the mixture to the construction ring. The second hollow plate 4 is fixedly connected to the outer wall of the synchronous shaft 18. The inner wall of the second hollow column 21 is fixedly connected to a limiting ring 25. The inner wall of the limiting ring 25 is slidably connected to a sliding column 22. One end of the sliding column 22 is fixedly connected to a scraper 24. The scraper 24, in conjunction with a spring 23, adaptively conforms to the tank wall under the action of centrifugal force and elasticity to achieve a self-cleaning effect. The outer wall of the scraper 24 is rotatably connected to the inside of the mixing tank 5. The outer wall of the sliding column 22 is slidably connected to the inside of the second hollow column 21. A spring 23 is provided on the outer wall of the sliding column 22. One end of the spring 23 is fixedly connected to the outer wall of the sliding column 22, and the other end of the spring 23 is fixedly connected to the side wall of the limiting ring 25.

[0039] Working principle: When using the highway construction material metering and batching device, when the batching process is started, the first motor 7 is powered on, and the motor output shaft rotates. Since the output end of the first motor 7 is fixedly connected to the screw rod 6, the screw rod 6 rotates inside the first hollow column 3. The spiral structure of the screw rod 6 uses the thrust generated by the rotation to push the material falling from the bottom of the hopper 1 into the first hollow column 3 continuously towards the hollow plate 4, forming the power basis for material conveying. The hydraulic cylinder 10 drives the rotating shaft 11 to move linearly. When the rotating shaft 11 moves under the action of the hydraulic cylinder 10, it drives the rotating plate 12 to rotate. Then, during the rotation of the rotating plate 12, it passes through the rotating block 14. The rotating plate 12 is connected to the support plate 13, which changes the linear motion of the rotating plate 12 into rotational motion. During the rotation of the rotating plate 12, the connecting column 15 fixed on its inner wall moves synchronously, thereby driving the sealing column 16 to rotate. The side wall of the sealing column 16 rotates and engages with one end of the first hollow column 3. By controlling the rotation angle and position of the sealing column 16, the opening and closing degree and conduction time of the discharge port of the first hollow column 3 are changed, and the amount of material falling into the hollow plate 4 and then into the mixing tank 5 per unit time is precisely controlled, so as to achieve quantitative discharge of materials and ensure that the amount of materials entering the subsequent mixing stage meets the preset ratio requirements. This solves the problem of unstable quality of the mixture caused by the inability to accurately control the ratio in traditional batching.

[0040] Next, the mixing tank 5 connected to the bottom of the hollow plate 4 is used to receive the metered materials. When the mixing process is started, the second motor 17 is powered on and started. Its output end drives the synchronous shaft 18 to rotate. The mixing blade 19 is fixedly connected to the outer wall of the synchronous shaft 18. The mixing blade 19 rotates with the synchronous shaft 18 inside the mixing tank 5. The rotating mixing action of the blades mixes and stirs the various materials in the tank, so that the different components of the road construction materials are evenly distributed to form a mixture that meets the construction requirements. After the mixing is completed, the discharge structure of the mixing tank 5 can be controlled to make the discharge plate 20 open. The mixed mixture is discharged through the discharge plate 20 and transported to the material use stage of road construction. When the synchronous shaft 18 rotates, the second hollow column 21 fixed on its outer wall rotates synchronously. At the same time, the limiting ring 25 plays a sliding limiting role on the internal sliding column 22. When the second hollow column 21 rotates with the synchronous shaft 18, the sliding column 22 and the scraper 24 rotate inside the mixing tank 5 under the action of centrifugal force and rotational inertia. Meanwhile, the spring 23 sleeved on the outer wall of the sliding column 22 keeps the scraper 24 in contact with the inner wall of the mixing tank 5. As the scraper 24 rotates with the synchronous shaft 18, it continuously scrapes the inner wall of the mixing tank 5, scraping off the residual material in the tank, avoiding the mixing of residual old material with new batch material, ensuring the accurate material ratio of each batching and mixing, and improving the performance stability of the mixture.
