Description

Technical Field

[0001] This utility model relates to the technical field of seedling raising devices, specifically a broad bean seedling raising device with photosynthesis capabilities. Background Technology

[0002] In agricultural production and plant research, seedling raising is a crucial part of the crop growth cycle. Broad beans, as an important legume, have high requirements for light and nutrients during seed germination and the early seedling growth stages. Sufficient and suitable light effectively promotes photosynthesis in broad bean seedlings, thus affecting their growth rate and robustness; while a stable and uniform nutrient supply is key to root development and plant growth.

[0003] Currently, existing seedling raising devices generally lack independent lighting systems, failing to meet the light requirements of broad bean seeds and limiting photosynthetic efficiency. Furthermore, common seedling raising devices such as seedling trays and plug trays have simple structures, and their nutrient solution supply methods (bottom soaking or top watering) easily lead to uneven nutrient solution distribution, localized hypoxia, or excessive fluctuations in nutrient concentration. This is particularly problematic for broad bean seedlings with sensitive root systems, as uneven nutrient supply affects the uniformity of root development and the efficiency of nutrient absorption. Therefore, there is an urgent need to develop a new type of seedling raising device specifically designed for the needs of broad bean seedling raising, capable of effectively promoting photosynthesis, optimizing nutrient supply, and improving operational convenience. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a broad bean seedling raising device with photosynthetic capabilities.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a broad bean seedling raising device with photosynthesis, including a light-emitting part and a seedling raising part, wherein a support frame is provided on the lower side of the light-emitting part, and the seedling raising part is arranged inside the support frame;

[0006] The seedling section includes an outer box and an inner box. The outer box has a support layer and a partition layer inside. The inner box is placed on top of the support layer. One end of the partition layer is connected to a through cavity. The upper part of the through cavity is connected to the upper side of the support layer. A circulating water pipe is laid at the bottom of the through layer. The circulating water pipe is laid along the lower side of the support layer. The outer end of the circulating water pipe is bent upward and laid to the upper inner side of the outer box. The opening of the outer end of the circulating water pipe faces the upper side of the partition layer. The nutrients on the upper side of the circulating layer flow through the through cavity and the circulating water pipe to achieve lateral circulation of the nutrients.

[0007] As an optimization, the support layer has several water-permeable holes, the entire support layer is immersed in the nutrient solution, the support layer forms a continuous arc-shaped structure, and the inner box is positioned in contact with the top of the arc-shaped structure.

[0008] As an optimization, the bottom surface of the inner box is provided with several water absorption holes, the top of the inner box is open, and the height of the inner box is greater than the distance between the support layer and the top of the outer box.

[0009] As an optimization, the lighting section includes a support frame and a lighting panel, the lighting panel being slidably connected to the support frame, the support frame being fixed to the bottom of the support frame, and the lighting panel being located directly above the seedling section.

[0010] As an optimization, the circulating water pipe is equipped with a water pump, and a through hole is provided in the upper part of the through cavity, the through hole being located on the upper side of the support layer.

[0011] As an optimization, handles are connected to two opposite sides of the inner box, and a limiting frame is provided on the top of the inner box. When the inner box is placed inside the outer box, the handles are located on the outside of the outer box, and the limiting frame is located on the upper side of the outer box.

[0012] The beneficial effects of this plan are as follows:

[0013] The integrated lighting system (support frame and sliding, height-adjustable lighting panel) provides a stable, adjustable, and appropriately positioned artificial light source for broad bean seedlings, ensuring that the seedlings receive sufficient light, effectively stimulating and enhancing their photosynthetic capacity, and promoting healthy and rapid growth.

[0014] Under the influence of gravity, the nutrient solution flows from the upper side of the partition layer through the through-cavity into the bottom circulating water pipe. The configured water pump drives the nutrient solution to flow in the circulating water pipe, realizing continuous and lateral circulation of the nutrient solution in the seedling area, rather than static soaking. This ensures more uniform distribution of the nutrient solution and stable nutrient concentration, while increasing the dissolved oxygen content of the water body. This creates an ideal environment rich in oxygen and nutrients for the broad bean roots, greatly improving nutrient absorption efficiency and root vitality. Attached Figure Description

Detailed Implementation

[0024] like Figures 1-8 As shown, a broad bean seedling raising device with photosynthesis includes a light-emitting part and a seedling raising part. A support frame 1 is provided on the lower side of the light-emitting part, and the seedling raising part is arranged inside the support frame 1.

[0025] The seedling section includes an outer box 2 and an inner box 3. The outer box 2 has a support layer 4 and a partition layer 5 inside. The inner box 3 is placed on the upper side of the support layer 4. One end of the partition layer 5 is connected to a through cavity 6. The upper part of the through cavity 6 communicates with the upper side of the support layer 4. A circulating water pipe 7 is laid at the bottom of the through layer. The circulating water pipe 7 is laid along the lower side of the support layer 4. The outer end of the circulating water pipe 7 is bent upward and laid to the upper inner side of the outer box 2. The outer end opening of the circulating water pipe 7 faces the upper side of the partition layer 5. The nutrient solution on the upper side of the circulating layer flows through the through cavity 6 and the circulating water pipe 7 to realize the lateral circulation of the nutrient solution.

[0026] The lighting panel 11 can use LED beads with a red-blue spectrum combination, with a recommended ratio of 7:3, covering a spectral range of 640–660nm (red light) and 450–460nm (blue light) to maximize the absorption of photosynthetic pigments by broad bean seedlings. Light intensity can be adjusted in segments via an external controller, using low-intensity light during the seedling stage and increasing to medium-high intensity light during the mid-growth stage to accelerate stem and leaf development.

[0027] The circulating water pipe 7 is set along the length of the outer box 2, and the nutrient solution is circulated laterally along the circulating water pipe 7 to avoid uneven distribution of nutrient solution concentration.

[0028] Nutrient solution enters the circulating water pipe 7 from the partition layer 5 through the through cavity 6, forming a "U-shaped backflow" below the arched support layer 4, so that the nutrient solution inside the outer box 2 maintains a pressure difference along the length direction. The nutrient solution permeates upward through the water permeable hole 8 to the water absorption hole 9 of the inner box 3, realizing bottom-up immersion supply and promoting the efficient absorption of nutrient solution by broad bean seedlings.

[0029] like Figure 4 and Figure 7 As shown, the support layer 4 has several water-permeable holes 8. The entire support layer 4 is immersed in the nutrient solution. The support layer 4 forms a continuous arc-shaped structure. The inner box 3 is in contact with the top of the arc-shaped structure.

[0030] The top of the arched structure supports the inner box 3, creating several ventilation gaps on the lower side of the inner box 3, which promotes air exchange around the roots of the broad bean seedlings and improves the overall air permeability of the device.

[0031] like Figure 4 and Figure 6 As shown, the bottom surface of the inner box 3 is provided with several water absorption holes 9, the top of the inner box 3 is open, and the height of the inner box 3 is greater than the distance between the top of the support layer 4 and the outer box 2.

[0032] The bottom water absorption hole 9 adopts a conical design, which can be in the form of an upper hole diameter of 2mm and a lower hole diameter of 1mm, to prevent substrate blockage and control water flow rate.

[0033] like Figure 1 As shown, the lighting section includes a support frame 10 and a lighting plate 11. The lighting plate 11 is slidably connected to the support frame 10. The support frame 1 is fixed to the bottom of the support frame 10, and the lighting plate 11 is located directly above the seedling section.

[0034] The side of the lighting panel 11 is provided with a connecting ear, which can slide along the support frame 10. A locking bolt is connected to the support frame 10, and the upper and lower sides of the connecting ear are locked and limited by the locking bolt.

[0035] like Figure 4 As shown, the circulating water pipe 7 is equipped with a water pump 12, and a through hole 13 is provided in the upper part of the through cavity 6. The through hole 13 is located on the upper side of the support layer 4.

[0036] like Figure 5 and Figure 6 As shown, handles 14 are connected to two opposite sides of the inner box 3, and a limiting frame 15 is provided on the top of the inner box 3. When the inner box 3 is placed inside the outer box 2, the handles 14 are located on the outside of the outer box 2, and the limiting frame 15 is located on the upper side of the outer box 2.

[0037] When using the device, the broad bean seeds are pretreated, such as sterilized and soaked. The planting substrate is then filled into the bottom of the inner box 3, compacted, and sprayed with water to keep the planting substrate moist. The broad bean seeds are then evenly spread on the planting substrate.

[0038] Nutrient solution was filled into the outer box 2, and water pump 12 was turned on to test the circulation smoothness.

[0039] Place the inner box 3 containing seeds inside the outer box 2, with the bottom of the inner box 3 in contact with the support layer 4, and the bottom of the inner box 3 immersed in the nutrient solution.

[0040] Adjust the height and intensity of the lighting panel 11 to provide light treatment for the broad bean seeds;

[0041] The nutrient solution is circulated by a liquid pump, according to... Figure 4 The direction shown allows the nutrient solution to circulate from left to right, creating a pressure difference between the left and right sides of the nutrient solution. This promotes the absorption of the nutrient solution by the broad bean seedlings and ensures the uniformity of the nutrient solution concentration.
