[0002] With the improvement of food production and processing technology, the storage mode and equipment of materials are also constantly updated. The traditional bin management method mostly relies on manual operation, with uneven feeding distribution, easy mixing and leakage of materials. The feeding direction is often relatively single, and materials can only be transported to one bin. When collecting materials in the traditional bin, it is time-consuming and laborious, and there are many human errors. In the process of feeding materials into the bin through a trough-shaped device, due to the inability to distribute the materials in the front section in a timely manner, the operation efficiency is low, and the materials in the front section often accumulate during the process of entering the bin, thus affecting the normal entry of materials into the bin.

[0038] There are five individual material bins arranged sequentially and connected to each other. The five bins are designated as bin 12, bin 13, bin 14, bin 15, and bin 16. Bin 12 has the same structure as bins 14 and 16, and bin 13 has the same structure as bin 15. Bin 13 is located between bins 12 and 14, and bin 15 is located between bins 14 and 16.

[0039] In this embodiment, the third plate of the first hopper 12 is the same as the first plate of the second hopper 13, the third plate of the second hopper 13 is the same as the first plate of the third hopper 14, the third plate of the third hopper 14 is the same as the first plate of the fourth hopper 15, and the third plate of the fourth hopper 15 is the same as the first plate of the fifth hopper 16.

[0040] There are three conveyor support plate groups arranged linearly, designated as the first conveyor support plate group 21, the second conveyor support plate group 22, and the third conveyor support plate group 23. There are five conveying components: the first conveying component 24, the second conveying component 25, the third conveying component 26, the fourth conveying component 27, and the fifth conveying component 28. The first conveying component 24 and the fifth conveying component 28 have identical structures, with the drive shaft and driven shaft of the first conveying component 24 parallel. The second, third, and fourth conveying components 25, 26, and 27 have identical structures, with the drive shaft of the second conveying component 25 positioned higher than its driven shaft. The second, third, and fourth conveying components 25, 26, and 27 are arranged in parallel. The first, second, third, and fourth conveying components 24, 25, 26, 27, and 28 are arranged in a stacked sequence.

[0041] The first conveying component 24 is mounted on the first conveying support plate assembly 21, with its conveyor belt positioned at the top of the first hopper 12 and the second hopper 13, respectively. The drive shaft of the second conveying component 25 is mounted on the first conveying support plate assembly 21, and its driven shaft is mounted on the second conveying support plate assembly 22. The drive shaft of the second conveying component 25 is positioned higher than the drive shaft of the first conveying component 24, and its conveyor belt is positioned at the top of the second hopper 13 and the third hopper 14, respectively. The third conveying component 26 is mounted on the second conveying support plate assembly 22, with its drive shaft positioned higher than the driven shaft of the second conveying component 25. Its conveyor belt is positioned at the top of the third hopper 14 and the fourth hopper 15, respectively. The drive shaft of the fourth conveying component 27 is mounted on the second conveying support plate group 22, and the driven shaft of the fourth conveying component 27 is mounted on the third conveying support plate group 23. The drive shaft of the fourth conveying component 27 is higher than the driven shaft of the third conveying component 26.

The drive shaft of the fifth conveying component 28 is higher than the driven shaft of the fourth conveying component 27, and the conveyor belt of the fifth conveying component 28 is located at the top of the fifth hopper 16.

[0042] In use, materials are placed on the conveyor belt of the first conveyor component 24, and then conveyed to the first hopper 12 or the second hopper 13 by the forward and reverse rotation of the corresponding conveyor motor. When materials are placed on the conveyor belt of the second conveyor component 25, the forward and reverse rotation of the conveyor motor of the second conveyor component 25 conveys the materials to the third hopper 14, or to the conveyor belt of the first conveyor component 24, where the materials are then distributed. When materials are placed on the conveyor belt of the third conveyor component 26, the forward and reverse rotation of the conveyor motor of the third conveyor component 26 conveys the materials to the fourth hopper 15, or to the conveyor belt of the second conveyor component 25. When materials are placed on the conveyor belt of the fourth conveyor component 27, the forward and reverse rotation of the conveyor motor of the fourth conveyor component 27 conveys the materials to the fifth hopper 16, or to the conveyor belt of the third conveyor component 26. When the material is placed on the conveyor belt of the fifth conveyor component 28, the conveyor motor of the fifth conveyor component 28 will rotate to transfer the material to the conveyor belt of the fourth conveyor component 27, and then to the corresponding hopper.

[0043] In this example, materials are placed on a conveyor belt using existing equipment. As the materials reach the end of the conveyor belt, they fall downwards under gravity into the corresponding bins. Different motors are controlled to operate according to actual usage needs, thus sequentially feeding materials into the first bin 12, the second bin 13, the third bin 14, the fourth bin 15, and the fifth bin 16. This ensures that the produced materials do not accumulate and are evenly distributed to each bin.

[0044] The design principle of this utility model mainly revolves around several core objectives: improving storage efficiency, saving floor space, achieving intelligent management, and reducing operating costs. Compared with traditional storage silo equipment, this utility model has the following features:

[0045] 1. High-density storage: This invention utilizes multiple three-dimensional silos for storage, enabling the silos to store more material within a limited space, thus achieving high-density storage. This effectively utilizes space and reduces land occupation.

[0046] 2. Mechanical conveying: This utility model uses motor power to drive the conveyor belt to feed materials into the hopper, reducing manual feeding operations and improving material storage efficiency and accuracy.

[0047] 3. Safety Design: The storage silo of this utility model takes into account safety issues such as overpressure, overflow, and material shortage. The weight is controlled by the first weight sensor 1051, the second weight sensor 1052, the third weight sensor 1053 and the fourth weight sensor 1054 installed at the bottom of the silo to ensure safe operation and accurate measurement of the silo.

[0048] 5. Energy saving and environmental protection: This utility model achieves green and environmentally friendly silo design by optimizing the lighting device 1062.

[0049] 6. Flexible adjustment: This utility model can quickly adjust the storage amount of materials in each silo according to changes in material storage needs, adapting to different storage requirements.

[0050] 7. Automatic Material Storage: Optimized material scheduling via weight sensors improves logistics efficiency and reduces waiting time. When the upper limit photoelectric switch 1061 detects a full hopper, it controls the corresponding conveyor motor to automatically transfer the material to another hopper, achieving automatic control of overpressure during roof collapse.
