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

[0033] See also Figure 1-7 Structural schematic diagram, the present invention provides the following technical solutions:

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

[0035] Among them, the storage silo body 1 is composed of a plurality of separate silos assembled and installed in a horizontal plane, which is convenient for installation and also convenient for reducing the overall height of the storage silo body 1. The number of storage silo bodies 1 is set according to the size of the site lanes to improve the versatility of the storage silo. For example, the installation position and length of the storage silo body 1 can be designed according to the actual situation on site, and after the design, it can be produced in sections and then transported to the site for installation. In addition, after use, the plurality of separate silos can be dismantled in sections to facilitate recycling and reuse when needed later, with low investment cost, low maintenance cost, and better practical value. Furthermore, each storage silo body 1 is configured as a trapezoidal silo body with a large top and a small bottom, so that the impact force of the material on the silo mouth can be reduced when unloading.

[0036] Please continue to see Figure 3 The tail roller 3 is provided with a screw spiral tensioning structure, which includes a mobile frame slidably connected to the storage bin body 1, on which a tensioning roller connected to the conveying belt 10 is rotatably installed, and on the storage bin body 1 a screw connected to the mobile frame is rotatably installed. During the transmission process, it can be adjusted according to the transmission state of the conveying belt 10, and can adjust the deviation of the conveying belt 10.

[0037] Please continue to see Figure 1 , the deviation correction roller 6 is installed in a V-shape. The conveying belt 10 with the deviation correction roller 6 installed in a V-shape will automatically correct to the V-shaped center of gravity under the effect of its own gravity, thereby reducing the probability of the conveying belt running off.

[0038] Please continue to see Figure 4 The hydraulic tensioning device 8 includes a tensioning winch 14, a hydraulic tensioning trolley 17, a tensioning oil cylinder 18 and a hydraulic pump station 19. The tensioning oil cylinder 18 is installed on a fixed seat through a cylinder support. A fixed rope seat for fixing the free end of a steel wire rope is installed on the fixed seat. A pulley block matching the steel wire rope is installed on the hydraulic tensioning trolley 17. The tensioning winch 14, the hydraulic tensioning trolley 17 and the tensioning oil cylinder 18 are connected by a steel wire rope transmission. A redirecting drum 15 matching the conveying belt 10 is installed on the hydraulic tensioning trolley 17. A pulley 20 is installed on one end of the tensioning oil cylinder 18 facing the hydraulic tensioning trolley 17. The hydraulic tensioning device 8 is for storing more conveying belts for later maintenance.

[0039] Please continue to see Figure 3 The weighing system 9 is located at the tail of the silo. By arranging multiple weighing systems 9 in cooperation with the conveying belt at the tail, the transported materials can be weighed, so that the operator can understand the weight of the transported materials in real time, and the real-time control of the coal flow rate is realized.

[0040] The weighing system 9 has multiple groups and is arranged side by side at the bottom of the conveying roller 4. Specifically, the weighing system 9 is penetrated by a support column, and a load-bearing roller in contact with the bottom of the conveying roller 4 is installed on the top of the support column through a swivel. A spring is sleeved on the support column, and the bottom end of the spring is pressed against the weighing system 9, and the top end of the bottom end of the spring is pressed against the swivel. In this way, when the load-bearing roller is squeezed by the weight of the material on the conveying belt 10, it moves downward along the support column, and the weight of the material acts on the weighing system 9 through the spring, so as to achieve the weighing of the material on the conveying belt 10. Among them, the weighing system 9 can include a mining explosion-proof weighing sensor.

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

[0042] In addition, 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, and ensure the smooth transportation of the material on the conveyor belt 10. In addition, the transmission signal of the weighing system 9 under the conveyor belt makes the conveyor belt move forward. The conveyor belt will move forward only when it receives a certain weight, which reduces the number of employees watching the belt, reduces costs and helps the intelligent management of the storage silo.

[0043] The metering buffer belt storage bin in the present invention is installed with an AI intelligent system control, and the AI ​​intelligent control system includes an AI image recognition module, an intelligent fault 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 stacking status.

[0045] The intelligent fault warning module predicts and issues fault warnings in advance 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 the start and stop of the conveyor belt 10 according to the material flow and material inventory in the warehouse identified by the AI ​​image recognition module and the preset production plan.

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

[0048] The remote monitoring and data analysis platform provides data visualization functions, which can intuitively display the equipment operation status, material handling efficiency and energy consumption in the form of charts, curves, etc., so that managers can make quick decisions and continuous optimization.

[0049] The unmanned automatic dispatching system automatically adjusts the conveying speed, tensioning degree and other parameters based on the actual situation on site and the production plan to achieve fully automated and unmanned production operations.

[0050] Adaptive learning module, which can continuously optimize the intelligent decision-making algorithm according to the historical data of equipment operation and manual intervention records, and improve the accuracy and efficiency of system control.

[0051] By setting up AI intelligent system control on the metering buffer belt storage silo, the metering buffer belt storage silo becomes an AI intelligent start and stop, unattended device, which reduces a large number of staff, has low investment cost, low maintenance cost, quick effect, and better practical value; during use, it can be adjusted according to the real-time status of each component to ensure the smooth operation of the metering buffer belt storage silo.

[0052] The working principle of the metering buffer belt storage bin provided by the present invention is as follows:

[0053] The material falls into the storage bin 1 at the rear of the machine, and 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 watching the belt.

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

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

[0056] In addition, the tail drum 3 is equipped with a screw spiral tensioner to adjust the belt deviation, and the tightness of the conveyor belt 10 can be automatically adjusted at any time by the hydraulic tensioner 8 without manual adjustment. All links have been improved many times.

[0057] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
