The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figure 1-7 Structural diagram; the present invention provides the following technical solution:

[0034] A metering buffer belt storage bin includes a storage bin body 1. A head roller 2 is installed on the bottom right side of the storage bin body 1, and a tail roller 3 is installed on the bottom left side of the storage bin body 1. A conveyor roller 4 is installed between the head roller 2 and the tail roller 3. A conveyor belt 10 is installed on the outside of the conveyor roller 4. A correction roller 6 is installed at the bottom of the conveyor belt 10, and anti-deviation vertical rollers 5 are installed on both sides of the correction roller 6. The anti-deviation vertical rollers 5 limit the conveyor belt 10 from both sides to maintain the smooth operation of the conveyor belt 10. A hydraulic tensioning device 8 is installed in the middle of the conveyor belt 10, and a weighing system 9 is installed at the bottom tail of the conveyor belt 10.

[0035] The storage silo 1 is composed of multiple individual silos assembled in a horizontal plane, facilitating installation and reducing the overall height of the silo 1. The number of storage silos 1 is determined by the size of the site's aisles to improve the versatility of the storage silos. For example, the installation position and length of the storage silo 1 can be designed according to the actual site conditions, manufactured in sections, and then transported to the site for installation. Furthermore, after use, the individual silos can be dismantled in sections for easy recycling and reuse when needed, resulting in low investment and maintenance costs and greater practical value. Moreover, each storage silo 1 is designed as a trapezoidal silo, wider at the top and narrower at the bottom, which reduces the impact force of materials on the silo opening during unloading.

[0036] Please continue reading Figure 3 The tail roller 3 is equipped with a screw-driven spiral tensioning structure, which includes a movable frame slidably connected to the storage bin 1. A tensioning roller connected to the conveyor belt 10 is rotatably mounted on the movable frame. A screw connected to the movable frame is rotatably mounted on the storage bin 1. During the conveying process, the screw can be adjusted according to the transmission status of the conveyor belt 10, and the deviation of the conveyor belt 10 can be adjusted.

[0037] Please continue reading Figure 1 The guiding roller 6 is installed in a V-shape. The conveyor belt 10, with the guiding roller 6 installed in a V-shape, will automatically correct itself towards the V-shaped center of gravity under its own weight, reducing the chance of the conveyor belt running off-center.

[0038] Please continue reading Figure 4The hydraulic tensioning device 8 includes a tensioning winch 14, a hydraulic tensioning trolley 17, a tensioning cylinder 18, and a hydraulic pump station 19. The tensioning cylinder 18 is mounted on a fixed base via a cylinder support. A rope fixing seat for fixing the free end of the wire rope is mounted on the fixed base. The hydraulic tensioning trolley 17 is equipped with a pulley block that works with the wire rope. The tensioning winch 14, the hydraulic tensioning trolley 17, and the tensioning cylinder 18 are connected by a wire rope drive. A redirecting roller 15 that works with the conveyor belt 10 is mounted on the hydraulic tensioning trolley 17. A pulley 20 is mounted on the end of the tensioning cylinder 18 facing the hydraulic tensioning trolley 17. The hydraulic tensioning device 8 is designed to store more conveyor belts for easier future maintenance.

[0039] Please continue reading Figure 3 The weighing system 9 is located at the rear of the silo. By setting multiple sets of weighing systems 9 that work with the conveyor belt at the rear end, the transported materials can be weighed, allowing operators to understand the weight of the transported materials in real time and realizing real-time control of coal flow rate.

[0040] Multiple weighing systems 9 are arranged side-by-side at the bottom of the conveyor rollers 4. Specifically, each weighing system 9 has a support column running through it, and a load-bearing roller that contacts the bottom of the conveyor rollers 4 is mounted on the top of the support column via a rotating base. A spring is fitted onto the support column, with its bottom end pressing against the weighing system 9 and its top end pressing against the rotating base. Thus, when the load-bearing roller is compressed by the weight of the material on the conveyor belt 10, it moves downwards along the support column, transferring the weight of the material to the weighing system 9 via the spring, thereby weighing the material on the conveyor belt 10. The weighing system 9 may include a mining explosion-proof load cell.

[0041] Please continue reading Figure 2 A drive roller 7 is installed in the middle of the conveyor belt 10, and a drive motor 12 is installed on one side of the storage silo 1. A drive reducer 13 is installed on the output shaft of the drive motor 12, and the output shaft of the drive reducer 13 is fixedly connected to one end of the drive roller 7 through a serpentine spring coupling 11. In order to store a large amount of material in the storage silo 1, the conveyor belt 10 needs a larger conveying force. Therefore, the serpentine spring coupling 11 is more suitable for high torque drive. Y-shaped anti-overflow skirts 16 are provided on both sides of the upper part of the conveyor belt 10, which can effectively prevent secondary leakage of materials.

[0042] Furthermore, the output power of the drive motor 12 can be adjusted in real time according to the weight of the material to avoid jamming or shutdown, ensuring smooth material transport on the conveyor belt 10. In addition, the conveyor belt moves forward only when it receives a certain weight, thanks to the signal transmitted by the weighing system 9 below it. This reduces the number of personnel required to monitor the belt, lowers costs, and facilitates intelligent management of the storage silo.

[0043] The metering buffer belt storage bin of this utility model is equipped with an AI intelligent system control system. The AI ​​intelligent control system includes an AI image recognition module, an intelligent fault early warning module, an automatic start-stop control module, a remote monitoring and data analysis platform, an unattended automatic scheduling system, and an adaptive learning module.

[0044] The AI ​​intelligent control system utilizes an AI image recognition module to monitor the material flow on the conveyor belt 10 in real time, including material type, flow rate, and accumulation status.

[0045] The intelligent fault early warning module predicts and issues early warnings of faults by analyzing equipment operating status data (such as motor current, belt tension, weighing system data, etc.).

[0046] The automatic start / stop control module intelligently decides whether to start or stop the conveyor belt 10 based on the material flow rate and material inventory in the warehouse identified by the AI ​​image recognition module, combined with the preset production plan.

[0047] The remote monitoring and data analysis platform supports remote monitoring of equipment operation status via mobile APP or web interface, real-time viewing of production data, and analysis of historical data to optimize production efficiency and equipment maintenance strategies.

[0048] The remote monitoring and data analysis platform provides data visualization capabilities, displaying equipment operating status, material handling efficiency, and energy consumption in the form of charts, curves, etc., which facilitates managers to make quick decisions and continuously optimize.

[0049] The unmanned automatic scheduling system automatically adjusts parameters such as conveying speed and tension based on the actual site conditions and production plan, realizing fully automated and unmanned production operations.

[0050] The adaptive learning module continuously optimizes the intelligent decision-making algorithm based on historical equipment operation data and human intervention records, thereby improving the accuracy and efficiency of system control.

[0051] By installing an AI intelligent system to control the metering buffer belt storage silo, the silo becomes an AI-intelligent start-stop, unattended device, reducing the number of staff, lowering investment and maintenance costs, and providing quick results with greater practical value. During use, it can adjust according to the real-time status of each component to ensure the stable operation of the metering buffer belt storage silo.

[0052] The working principle of the metering buffer belt storage silo provided by this utility model is as follows:

[0053] The material falls into the storage bin 1 at the tail of the machine. The transmission signal of the weighing system 9 under the conveyor belt 10 causes the conveyor belt 10 to move forward. Because the weighing system 9 is installed, the conveyor belt 10 will only move forward when it receives a certain weight, reducing the number of employees who need to watch the belt.

[0054] Y-shaped anti-overflow skirts 16 are installed on both sides of the conveyor belt 10 to effectively prevent secondary leakage of materials.

[0055] The drive system (including drive motor 12 and drive reducer 13) is equipped with serpentine spring coupling 11, which is more suitable for high torque drive, so that the storage bin 1 can store a large amount of material. In order to ensure the normal operation of the head roller 2 and tail roller 3, a centralized lubrication system is installed in the lubrication parts, eliminating the need for manual maintenance.

[0056] In addition, the tail roller 3 is equipped with a screw screw tensioner to adjust belt deviation. The tension of the conveyor belt 10 can be automatically adjusted at any time by the hydraulic tensioning device 8 without manual adjustment. All aspects have been improved many times.

[0057] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
