Description

Technical Field

[0001] This utility model relates to the field of grain storage, specifically to containerized grain storage stacks. Background Technology

[0002] A grain warehouse is a specialized building for storing grain. Based on its type, it can be divided into room-type warehouses, vertical silos, and other structures. It mainly includes warehouses, storage yards (or drying yards), and facilities for metering, conveying, stacking, cleaning, loading and unloading, ventilation, and drying, and is equipped with measuring, sampling, inspection, and testing instruments.

[0003] Traditional grain storage warehouses have some drawbacks, mainly including:

[0004] Inadequate facilities: Many traditional grain warehouses are built to low standards and have inadequate facilities, which may make the grain susceptible to pests, mold and rodents during storage, resulting in losses.

[0005] Outdated technology: Traditional warehouses may lack modern grain storage technologies, such as electronic temperature measurement, mechanical ventilation, and internal circulation temperature control. These technologies can effectively maintain the freshness and quality of grain and reduce losses.

[0006] Inefficient: Traditional grain storage operations often rely on manual labor, which is inefficient and difficult to adapt to the needs of large-scale, high-efficiency grain storage.

[0007] Unreasonable regional distribution: The uneven distribution of grain storage facilities in some areas leads to difficulties in grain storage and increases transportation costs and time.

[0008] High loss rate: Due to the above-mentioned reasons, the loss rate of traditional grain storage methods is relatively high. According to reports, farmers can suffer losses of about 8% in the grain storage process.

[0009] However, existing containers cannot be used directly for storing grain because they lack temperature and humidity control modules, and if the inside of the container is filled with air, the problem of grain oxidation cannot be avoided.

[0010] Therefore, this utility model provides a container grain storage stack. Utility Model Content

[0020] Preferably, it also includes several transport lanes for trucks to travel on, the transport lanes being parallel to the rails and passing under the cantilever crane.

[0021] Preferably, the transport lane is located on the side of the inflatable charging station away from the track.

[0022] Preferably, the stacker crane receives the grain storage containers hoisted from the truck below the cantilever crane and drives along the track to the target container storage position in the container rack to store the grain storage containers.

[0023] Preferably, the stacker crane carries the grain storage container to be charged and inflated, and drives along the track to the first end of the track, where the cantilever crane lifts the grain storage container to be charged and inflated to the charging station and docks with it.

[0053] In a preferred embodiment, the inflatable charging station 6 is located on at least one side of the first end of the track 7, but is not limited thereto.

[0054] In a preferred embodiment, the system also includes a plurality of transport lanes for the truck 5 to travel on, the transport lanes being parallel to the track 7 and passing through the area below the cantilever crane 1, but not limited thereto.

[0055] In a preferred embodiment, the transport lane is located on the side of the inflatable charging station 6 away from the track 7, but this is not a limitation.

[0056] In a preferred embodiment, the stacker crane 2 receives the grain storage container 3 hoisted from the truck 5 below the cantilever crane 1 and drives along the track 7 to the target container storage position 41 in the container rack 4 to store the grain storage container 3, but is not limited thereto.

[0057] In a preferred embodiment, the stacker crane 2 carries the grain storage container 3 to be charged and inflated, and moves along the track 7 to the first end of the track 7, so that the cantilever crane 1 can lift the grain storage container 3 to be charged and inflated to the charging station 6 and dock it, but this is not a limitation.

[0061] The use of containerized grain storage in this utility model has several advantages, mainly including:

[0062] Efficient loading and unloading: Containers can be loaded and unloaded automatically, improving operational efficiency and reducing manual labor intensity and time costs.

[0063] Reduced losses: The excellent sealing of containers can effectively prevent grain from being affected by moisture, mold, pests, and rodents during storage and transportation, thereby reducing losses.

[0064] Flexibility and mobility: Containers are easy to move and stack, and can be quickly adjusted in terms of storage location and quantity to adapt to different storage needs.

[0065] Standardization and compatibility: The standardized design of containers allows grain to be easily transferred between different modes of transport, such as from trucks to trains or ships, improving the compatibility and convenience of logistics.

[0066] Safety: The robust structure of the container protects the grain from the effects of the external environment, and the container can be equipped with an advanced monitoring system to monitor the grain status in real time.

[0067] Cost-effectiveness: Although the initial investment may be high, the durability and reusability of containers can reduce the overall cost in the long run.

[0068] Highly adaptable to the environment: Containers can be used in various climates and environments, without being restricted by geographical location.

[0069] Facilitates supervision and tracking: Containers are easy to seal and lock, which is conducive to the supervision and tracking of food, ensuring the transparency and security of the supply chain.

[0070] Therefore, a three-dimensional grain container stacking system was developed to realize the intelligent and automated storage of grain in containers.

[0071] Compared to traditional container handling systems, where stacker cranes typically transport containers to their designated location (outbound trip) and then return empty (return trip), the traditional system requires the stacker crane to return to its starting point after completing its task (even if empty) to save time for subsequent tasks. This process results in the stacker crane operating empty, reducing overall efficiency and hindering energy conservation and environmental protection. In this invention, the return trip is fully utilized by bringing containers requiring charging or inflation back to the first end of the track. This allows for charging and inflation using these containers, avoiding the stacker crane's empty return trip, further enhancing system uptime and improving energy efficiency and environmental friendliness.

[0072] The specific implementation of this utility model is as follows:

[0073] Continue to refer to Figures 1 to 3In this invention, the bottom of the grain storage container 3 in the container grain storage stack is provided with a first charging and inflation interface. Container racks 4 are arranged on both sides of a track 7. Each container rack includes several container storage positions 41 arranged in a vertical matrix for storing grain containers 3. Each container storage position 41 has a support portion that only supports the corner of the grain container 3, and is suspended above the center of the bottom surface of the grain container 3 to form an insertion space. At least one stacker crane 2 is provided. The stacker crane 2 has liftable horizontal forks that move along the track 7, allowing the horizontal forks to enter and exit the insertion space based on the side of the stacker crane 2, lifting or lowering the grain container 3 to transport the grain container 3 between the stacker crane 2 and the container storage positions 41. Several inflation and charging stations 6 are provided, each with a second charging and inflation interface vertically upwards for connecting the first charging and inflation interface vertically. A cantilever crane 1 lifts the grain container 3 between the horizontal forks, the truck 5, and the inflation and charging stations 6. The first end of the track 7 extends below the cantilever crane 1, and the second end passes through the container rack 4. The inflatable charging station 6 is located on at least one side of the first end of track 7. Several transport lanes for trucks 5 run parallel to track 7, passing under the cantilever crane 1. These transport lanes are located on the side of the inflatable charging station 6 opposite to track 7. The stacker crane 2 receives the grain container 3 hoisted from the truck 5 below the cantilever crane 1 and travels along track 7 to the target container storage position 41 in the container rack 4 to store the grain container 3. The stacker crane 2, carrying the grain container 3 to be inflated, travels along track 7 to the first end of track 7, where the cantilever crane 1 hoists the grain container 3 to be inflated onto the inflatable charging station 6 and docks it. The cantilever crane 1 vertically hoists the grain container 3 to be inflated onto the upper surface of the container, vertically connecting the first and second charging / inflating interfaces. The first charging and inflation interface is connected to the charging line and the inflation pipeline respectively. The charging line is connected to the temperature control system inside the grain storage container 3, and the inflation pipeline is connected to the grain storage cavity inside the grain storage container 3. When the first charging and inflation interface is connected to the second charging and inflation interface, the inflation charging station 6 supplies power to the temperature control system and delivers the anti-oxidation gas in the inflation charging station 6 to the grain storage cavity. The first ends of several tracks 7 extend to the bottom of the same cantilever crane 1 to share the cantilever crane 1 for lifting.

[0074] The process of transporting a container to its designated location on a one-way trip (outbound) mainly includes the following steps: First, truck 5 transports the grain container 3 to be stored to the area below the cantilever crane 1. The cantilever crane 1 then moves the grain container 3 laterally over the inflatable charging station 6 and onto the stacker crane 2. The stacker crane 2 travels along track 7 towards the container rack 4, reaching the side of the container storage location 41, which serves as the target storage location. Finally, the stacker crane 2 lifts the grain container 3 and places it into the target storage location.

[0075] After completing the outbound journey, the process of returning to the starting position (return journey) with the grain storage container 3 to be charged and inflated mainly includes: the stacker crane 2 prioritizes selecting the grain storage container to be charged and inflated that is closest to the target position's container storage space 41 along the return direction of the track. The stacker crane 2 removes the grain storage container 3 to be charged and inflated from the container storage space 41. The stacker crane 2 carries the grain storage container 3 to be charged and inflated along the track to the first end of the track. The cantilever crane 1 lifts the grain storage container to be charged and inflated above the inflating and charging station 6, supplies power to the temperature control system inside the grain storage container, and replenishes the grain storage cavity inside the grain storage container with anti-oxidation gas.

[0076] In this invention, when the stacker crane 2 is on its outbound journey (entering the container rack 4), it can move the containers to be stored into the corresponding positions on the container rack 4. On its return journey (leaving the container rack 4), it can move the grain storage containers 3 to be charged and inflated from the container rack 4 for charging and inflating. This ensures that the stacker crane 2 can be fully loaded throughout the entire process, avoiding the situation where the stacker crane 2 returns to the starting point empty, and greatly improving the operating efficiency of the system.

[0077] In summary, the purpose of this utility model is to provide a container grain storage stack that can use a crane to lift containers or rotate container doors between trucks and container sleds on multiple lanes. This restricts the necessary paths of trucks within the yard, preventing them from approaching the container storage area. It also helps reduce the width of roads within the container yard, thus providing more container storage space. Furthermore, it is beneficial for use with intelligent container racks, shortening the time cycle for storing and retrieving containers, and improving the storage capacity and turnover efficiency of the container yard.

[0078] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
