[0028] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0029] As Figure 1 shown, a novel rice cultivation device of the present application includes a multi-layer cultivation tray 1, a support frame 2, a connecting rod 3, a cross beam 4, an adjusting nut 5 and a reinforcing plate 6.

[0030] The multi-layer cultivation tray 1 of the device is used to place rice seedlings. The multi-layer cultivation tray 1 is of a planar structure and is composed of a plurality of grids to fix and support rice seedlings at different stages, to ensure sufficient light and air permeability area, so that the root system can grow smoothly. Each grid is provided with a drainage hole to prevent waterlogging and root rot, and to help control the irrigation amount. In the example, the plastic material is integrally formed by blow molding, has sufficient strength and light weight, and is convenient to carry and disassemble. In long-term soaking experiments, it is found that the water resistance is good and there is no obvious deformation, which ensures the service life of the device.

[0031] Support frame 2 is used to fix and support the multi-layer cultivation trays 1. Support frame 2 has a tower-shaped structure, mainly composed of hollow metal tubes, which have good malleability and corrosion resistance. The tower body adopts a segmented assembly method, allowing the operator to adjust the height of the support according to specific usage needs. Each section is locked together with snap-fits or screws, forming a compact and stable whole; each cultivation tray is correspondingly installed on the platform of the appropriate level. As the rice gradually grows taller, the user can gradually increase the overall height of the cultivation device or replace the modules of suitable length to rebuild the support, thereby meeting the ever-changing growth space requirements.

[0032] The connecting rod 3 serves to establish a stable mechanical connection between each layer of cultivation tray 1 and the support frame 2, preventing accidents such as tilting or falling of the cultivation tray due to excessive negative pressure on one side. It also helps to distribute the vertically downward pressure load and protect the lower components. This type of rod is usually a slender metal component arranged vertically, with through-holes near the top for inserting pins to fix it to the upper level platform. The bottom is a blind end structure with an internal thread after matching the pitch, so that it can be screwed into the cavity of the support leg with a protruding plunger to complete the mechanical engagement.

[0033] The crossbeam 4, located at the top and bottom, firmly establishes the support frame 2 into a rectangular doorway. The crossbeam 4 not only enhances the structural stability of the device but also serves a load-bearing function, playing a crucial role in the overall structure.

[0034] like Figure 2 As shown, the adjusting nut 5 can be, for example, an internally threaded blind-end structure as described above, directly sleeved onto the extended section of the connecting rod 3 with a sufficient length. It contains finely ground threaded grooves inside, serving as a transmission component to work with external tools for lifting and lowering adjustments. Users can freely fine-tune any one or more positions according to the actual crop conditions, making the multi-level shelving system more suitable for the specific needs of different planting varieties. The widely available small hexagonal adjusting heads made of aluminum alloy meet the above functional descriptions, and due to their light weight, they do not add much burden.

[0035] The reinforcing plate 6 is placed below the base layer as a reinforcement accessory, improving the area's resistance to bending moments while compensating for any potential weak points in the load-bearing structure. Its shape and dimensions are custom-cut to fit the bottom geometry of the base plate, ensuring a tight fit without noticeable gaps. The thickness is chosen to be appropriately proportioned, avoiding both excessive thinness that would compromise the reinforcement effect and excessive thickness that would increase unnecessary construction costs.

[0036] The aforementioned features effectively address the problem of uneven gravity distribution caused by the increased weight of plant roots absorbing water and the growth of rice seedlings in three-dimensional planting using multi-layer cultivation trays 1, which can lead to deformation or cracking of the bottom cultivation trays. The segmented adjustable support frame 2 allows operators to flexibly adjust the height of each layer, maintaining a suitable spatial layout. Simultaneously, the reinforcing plate 6 significantly enhances the bottom load-bearing capacity and rigidity, providing long-term stable support for the self-weight of the multi-layer structure plus the additional load from plant growth, reducing the risk of deformation and breakage. The crossbeam 4 enhances the overall structural rigidity, while the connecting rod 3 and adjusting nut 5 ensure even stress distribution across all layers, reducing undue pressure on any single layer. Through scientific and rational material selection and optimized design details, this rice cultivation device is not only structurally stable and durable but also creates an ideal three-dimensional planting environment for the healthy growth of rice seedlings.

[0037] In one embodiment, the multi-layer cultivation tray 1 of the novel rice cultivation device of this application is made of high-strength composite material. This material has excellent weather resistance and impact resistance, and can effectively prevent deformation or cracking caused by uneven weight distribution during long-term use. This type of composite material is chosen primarily because it can withstand the influence of various environmental factors, such as sunlight, moisture, and temperature differences, ensuring the long-term stability of the cultivation tray in outdoor or greenhouse environments. By selecting high-quality materials, not only is the overall durability of the device improved, but a stable carrier is also provided for rice seedling growth.

[0038] The multi-layer cultivation tray 1 occupies a crucial position in the device, directly bearing the weight of the planting medium and rice seedlings. The support frame 2, as the main support component of the entire device, provides a stable foundation for the multi-layer cultivation tray 1. Connecting rods 3 are located between each cultivation tray and the support frame 2, ensuring that each cultivation tray is placed horizontally and that the weight is evenly distributed. To further enhance the structural stability, crossbeams 4 are fixed to the upper and lower ends of the support frame 2, enhancing the overall rigidity of the support frame 2 and providing a secure suspension point for each cultivation tray. Adjusting nuts 5 are installed on the connecting rods 3, allowing for fine-tuning of the height of each cultivation tray to ensure uniform spacing between layers. A reinforcing plate 6 is also installed below the bottom cultivation tray to strengthen the bottom's load-bearing capacity and prevent permanent deformation due to prolonged exposure to high pressure. All these components are securely connected together with fasteners such as screws or rivets, ensuring the overall strength and stability of the device.

[0039] In one embodiment, such as Figure 3As shown, the multi-layer cultivation tray 1 of the novel rice cultivation device of this application has multiple support columns 7 installed at its bottom. These support columns 7 are evenly distributed at the bottom of the cultivation tray, effectively enhancing its load-bearing capacity and overall stability. The connection between the support columns 7 and the bottom of the cultivation tray ensures the uniform transmission and distribution of gravity, reducing the risk of deformation or cracking due to excessive local load.

[0040] Specifically, the lower part of the support column 7 is further provided with multiple reinforcing ribs 8, which form a grid structure, not only reinforcing the support column 7 itself, but also improving the overall compressive strength. The design of the reinforcing ribs 8 increases the interaction and support between materials, thereby ensuring the structural strength and long-term durability.

[0041] The support column 7 has a height adjustment function to meet the space requirements of rice seedlings at different growth stages. This is achieved by creating several positioning holes 9 on the support column 7 and fixing their positions using adjusting pins 10. Users can adjust the height by inserting the adjusting pin 10 into the appropriate positioning hole 9 according to their actual needs. This operation is flexible and convenient, while ensuring the consistency of position of each layer of cultivation trays and the overall balance of the system.

[0042] For example, in actual planting, as the rice seedlings grow, growers can easily optimize the spatial layout by changing the insertion points of the adjusting pins 10 on the support column 7, ensuring a reasonable environment for the healthy growth of the rice seedlings and maintaining a suitable spacing between the cultivation trays at each level. The entire design cleverly integrates mechanical principles and agronomic requirements to ensure efficient and stable hydroponic conditions.

[0043] In one embodiment, such as Figure 4 As shown, the support frame 2 of the novel rice cultivation device of this application is composed of multiple sections of pipe 11 spliced ​​together. This design allows users to flexibly adjust the height of the support frame 2 according to actual conditions and needs. The pipes 11 are connected to each other by quick connectors 12, ensuring simple and quick operation during splicing while maintaining the overall stability and structural rigidity of the support frame 2. The quick connectors 12 are equipped with rubber gaskets 13. This structural detail provides effective cushioning and shock absorption during assembly or daily use to avoid potential structural damage caused by prolonged exposure to gravity.

[0044] The outer surface of the support frame 2 is specially treated to form an anti-slip coating, which is optimized for humid environments. This effectively enhances the grip performance required when placing the equipment in high humidity environments, thereby reducing the possibility of slippage during installation or subsequent movement and ensuring that the cultivation device operates in a more stable state.

[0045] Specifically, each section of independently processed pipe 11 can be cut to a predetermined length and its end face flatness can be ensured to meet the specified requirements before being assembled. The pipes 11 are precisely connected by quick connectors 12 with built-in rubber gaskets 13. At the same time, a uniform and firmly bonded professional-grade anti-slip coating 14 is applied to the surface of all pipes that make up the support frame 2 to ensure that they still have good friction under wet conditions. In the end, a rice seedling planting auxiliary facility that not only meets the height adjustment requirements but also has high reliability and safety is obtained.

[0046] In one embodiment, the crossbeam 4 of the novel rice cultivation device of this application adopts a detachable design. The crossbeam 4 is fixed to the top and bottom of the support frame 2, not only enhancing the overall structural stability and rigidity but also providing stable suspension points for each layer of cultivation trays. When disassembly is required, the crossbeam 4 can be quickly removed by loosening the locking mechanism at the installation position, making operation more convenient and efficient. This design fully considers the needs of practical applications, making daily inspection and maintenance easier.

[0047] Specifically, a dedicated locking mechanism 15 is provided between both ends of the crossbeam 4 and the support frame 2. This locking mechanism 15 securely locks the crossbeam 4 to the support frame 2 and is easy to release, allowing for quick separation of the crossbeam 4 from the support frame 2 when necessary. Specifically, the locking mechanism 15 can be implemented using a pin-type or snap-lock design, ensuring both the security and reliability of the connection while ensuring a simple and easy unlocking process. For example, the unlocking action can be completed by manually turning a knob, thus achieving rapid assembly and disassembly of the crossbeam 4.

[0048] In one embodiment, the adjusting nut 5 of the novel rice cultivation device of this application has a butterfly-shaped design. This special shape allows for direct hand-tightening without tools, increasing the ease of adjustment and ensuring rapid adjustments in various scenarios. This feature enables users to easily change the height of the cultivation trays according to actual conditions, precisely controlling the spacing between multiple trays to ensure consistency and effectively maintain the stability of the entire device.

[0049] For example, during installation, the butterfly-shaped adjusting nut 5 is positioned between the connecting rod 3 and each cultivation tray. This nut has a large, textured handle and a long, narrow through-hole running through its center. After fitting it onto the connecting rod 3, it is secured with the matching fastening components. For fine-tuning the height, simply loosen the adjusting nut 5, slide the cultivation tray up and down to the desired position, and then tighten the fastener. This cleverly solves the problem of requiring wrenches or other auxiliary tools in traditional methods, further improving assembly and subsequent adjustment efficiency. Stepless fine adjustment can be achieved by manually rotating the adjusting nut 5, ensuring accurate and consistent spacing between each cultivation tray. Furthermore, this unique nut shape design facilitates identification and operation, reducing the risk of misoperation. The connection structure ensures a stable locked state even after prolonged use, preventing loosening.

[0050] In one embodiment, the reinforcing plate 6 of the novel rice cultivation device of this application is made of high-density aluminum alloy. The thickness of the reinforcing plate 6 is not less than 5 mm, thus ensuring high strength and rigidity. The reinforcing plate 6 is installed below the lowest cultivation tray, serving as the main support component bearing the weight of the bottom cultivation tray. This design not only effectively prevents the bottom cultivation tray from deforming or cracking under pressure, but also maintains the structural stability and reliability over a long period. During installation, the reinforcing plate 6 is fixed to the bottom crossbeam 4 using robust fasteners such as screws or rivets, ensuring a secure connection. This material selection and thickness design are intended to provide sufficient compressive strength and durability.

[0051] For example, high-density aluminum alloy sheets that meet standards can be selected and processed to specified dimensions using professional cutting tools to ensure that the actual thickness of the reinforcing plate 6 meets or exceeds design requirements. The joints between the reinforcing plate 6 and the crossbeam 4, as well as the bottom cultivation tray, should be specially reinforced, for example by adding washers or increasing the contact area, to further improve the bonding strength and meet the needs of long-term use. This ensures that the entire cultivation device maintains structural stability and load-bearing capacity regardless of the different growth stages of the rice seedlings.

[0052] In one embodiment, the reinforcing plate 6 of the novel rice cultivation device of this application is precisely sized to be slightly smaller than the bottom of the cultivation tray. This design ensures that during use, the reinforcing plate 6 does not extend beyond the edge of the cultivation tray while still covering most of the bottom area of ​​the tray, thus providing adequate support and pressure distribution. The design of the reinforcing plate 6, located below the cultivation tray and sized to match the tray, helps optimize the layout and functionality of the entire device, avoids waste of materials and space, and improves the overall structural compactness.

[0053] In this novel rice cultivation device, the reinforcing plate 6, through its specific size and shape design, effectively prevents deformation or cracking of the bottom cultivation tray due to localized stress concentration. By rationally arranging the size and placement of the reinforcing plate 6, its supporting and shock-absorbing functions are maximized without encroaching on cultivation space. To better adapt to practical application needs, the reinforcing plate 6 is made of pressure-resistant material and undergoes special treatment to improve its durability and anti-aging properties, ensuring stability and reliability under long-term loads.

[0054] For example, the reinforcing plate 6 can be fixed to the bottommost cultivation tray with screws or rivets, directly installed between the crossbeams 4 on the support frame 2, which further enhances the overall rigidity and stability of the device. Specifically, once the reinforcing plate 6 is installed, it can not only bear the weight load transmitted from all the upper cultivation layers, but also evenly distribute these forces to the support frame 2 and other related structural components, thereby making the cultivation environment of each layer more stable and conducive to the healthy growth of rice seedlings. In addition, by carefully adjusting the thickness and material selection of the reinforcing plate 6, it meets the strength requirements without affecting the air circulation between cultivation trays and other operations.

[0055] In actual operation, when this device is used, rice seedlings are placed in the corresponding positions on the multi-layer cultivation trays 1. Then, according to the growth height requirements of the rice seedlings, the height of each layer of cultivation trays is adjusted by segmenting the support frame 2 to ensure that each layer is in a suitable position. The connecting rod 3 and adjusting nut 5 ensure uniform distance between each layer of cultivation trays and maintain horizontal stability. Fine adjustments can be made by rotating the adjusting nut 5 to meet different planting needs. The crossbeam 4 provides additional support at the top and bottom of the support frame 2, enhancing the overall structural stability and rigidity, and ensuring that each layer of cultivation trays has a stable suspension point. The reinforcing plate 6 installed below the bottommost cultivation tray increases the load-bearing capacity and prevents deformation due to gravity during long-term use. All components are securely connected by fasteners, ensuring the safety and durability of the entire device. After these adjustments are completed, the new rice cultivation device provides a stable and suitable environment for rice growth.
