Description

Technical Field

[0001] This utility model belongs to the field of hydroponic seedling cultivation technology of oak plants, and specifically relates to a hydroponic seedling cultivation device for oak plants. Background Technology

[0002] Oak (Quercus) is the largest tree species group in my country, possessing advantages such as "native habitat, longevity, resilience, food source, and aesthetic appeal." It is an important native tree species in Beijing and can be stably mixed with various coniferous and broad-leaved trees, making it an excellent species for creating soil and water conservation forests. Currently, most oak species used in landscaping are artificially propagated to improve seedling quality. However, traditional substrate container seedling cultivation makes it difficult to thoroughly clean the substrate, hindering research on oak seedling root systems and nutrient absorption and utilization. Therefore, in the initial stages of artificial seedling cultivation of oak, hydroponics is often used, where seeds are fixed to seedling trays in seedling boxes, allowing for research or transplanting once the seedlings reach the expected size.

[0003] Because oak seeds are relatively large and their germination process differs from that of common tree species, after germination, the seeds need to be placed with the pointed end (germination point) facing down or tilted so that the seed roots can directly contact the nutrient solution after breaking through the seed coat, facilitating seedling growth. Currently, the fixation of oak seeds during the seedling cultivation process mostly uses disposable sponges. The purchased sponges need to be manually cut or trimmed into the required shapes one by one, which is labor-intensive. Moreover, after the seedlings are removed, the sponges are directly discarded and cannot be reused, which is not environmentally friendly.

[0004] To address this, we designed a hydroponic seedling cultivation device for oak plants. Utility Model Content

[0005] The purpose of this invention is to provide a hydroponic seedling cultivation device for oak plants, in order to solve the aforementioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hydroponic seedling cultivation device for oak plants includes a water tank and a support assembly fixed to the top of the water tank.

[0008] Furthermore, the support assembly is equipped with several grating plates, which divide the inside of the water tank into several seedling trays for cultivating seedlings. Each seedling tray is detachably equipped with a set of seed-bearing components at its top.

[0009] Furthermore, the seed-carrying assembly includes a carrier plate frame and a support frame for fixing the seeds.

[0010] Furthermore, the support frame is detachably snapped into the middle position of the carrier plate frame.

[0011] Furthermore, the water tank is a square box design, with an inlet and a drain with a water valve switch on the top and bottom of the side of the water tank, respectively. The four edges of the top of the water tank are provided with bracket slots for engaging the support components.

[0012] Furthermore, a bracket slot is provided on each of the four edges of the top of the water tank corresponding to the position of the seedling tray, and a side bracket for installing the seed-carrying component is attached to each bracket slot to cooperate with the grid plate.

[0013] Furthermore, the support assembly includes several horizontal frames and several vertical frames, which are detachably connected together by wedges. Each horizontal and vertical frame in the support assembly has a through slot for inserting a grid plate at the edge of each seedling trough. Each horizontal and vertical frame has a positioning notch at both ends of each through slot. The ends of the horizontal and vertical frames are respectively engaged in the bracket slots on the edge of the water tank.

[0014] Furthermore, the grating plate includes a rectangular grating plate body, and an "L"-shaped support bracket is integrally formed on both sides of the top of the grating plate body corresponding to the positioning notch. The support bracket and the side bracket have the same structure and are at the same horizontal height. Positioning slots are opened on the edge of the support platform of both the support bracket and the side bracket.

[0015] Furthermore, the carrier plate frame in the seed carrier assembly includes a rectangular hollow plate. The center of the hollow plate is provided with an installation hole for assembling the carrier frame. A positioning ring is provided around the edge of the installation hole. The edge of the hollow plate is integrally formed with a positioning block that engages with the positioning slot. The hollow plate is placed flat on the carrier bracket and side bracket set on the top of the corresponding seedling trough.

[0016] Furthermore, the support frame is designed as a ring, and includes three arc-shaped retaining edges that are spliced ​​together. The three retaining edges are spliced ​​together to form a ring structure that is inserted into the mounting hole. Each retaining edge has several support parts that are equidistantly formed at its bottom and inclined toward the center of the mounting hole. Each support part has a clamping part that is set in the opposite direction at its bottom.

[0017] Furthermore, both the support portion and the clamping portion are narrow and elongated, and the transition between the clamping portion and the support portion adopts a vertical angle design.

[0018] Furthermore, the water tank, support assembly, grating plate, side bracket, and seed carrying assembly are all made of plastic.

[0019] Furthermore, the water tank is 25-40 cm deep, and the edge of each seedling trough is a square structure with a side length of 10-15 cm.

[0020] Beneficial effects:

[0021] This invention uses a water tank as the main body, and utilizes a support component and several partition plates to divide the inside of the water tank into several seedling trays of equal size for cultivating oak seeds. Each partition plate adopts a mesh grid structure, allowing each seedling tray to be interconnected, which is conducive to the injection and discharge of nutrient solution. In addition, this device uses a detachable seed-bearing component to replace the sponge structure used for fixing oak seeds in seedling cultivation. This not only satisfies the need for effective seed fixation, but also allows for rapid detachment of the root system of the seedlings during emergence. All components are reusable, which is convenient and environmentally friendly. Furthermore, combined with the elastic design of the seed-bearing component, it can accommodate the fixation of various oak seeds of different sizes without damaging the seed body. Its adaptability is strong and beneficial to the seedling cultivation operation of oak seeds. Attached Figure Description

[0030] Example

[0031] To address the issues of labor-intensive and environmentally unfriendly hydroponic seed culture devices used in traditional Quercus artificial breeding and seedling cultivation, which generate significant amounts of disposable waste after each batch of seedlings, we propose a convenient and reusable hydroponic seed culture device for Quercus seeds. The device consists of a water tank 1 as the main body, with supporting components 2 and several partition plates 3 dividing the interior of the water tank 1 into numerous equal-sized seedling trays for cultivating Quercus seeds. Each partition plate 3 employs a mesh grid structure, ensuring interconnectivity between the seedling trays. This design facilitates the injection and drainage of the nutrient solution. Furthermore, the device employs a detachable seed-bearing component 5 to replace the traditional sponge structure used for fixing oak seeds during seedling cultivation. This not only ensures effective seed fixation but also allows for rapid detachment of the seedling roots during emergence. All components are reusable, making it convenient and environmentally friendly. The elastic design of the seed-bearing component 5 allows for the fixation of various oak seeds of different sizes without damaging the seed itself, demonstrating strong adaptability and facilitating oak seedling cultivation. The specific details are as follows:

[0032] like Figures 1-2 As shown, this embodiment provides a hydroponic seedling cultivation device for oak plants, including a water tank 1 and a support assembly 2 fixed to the top of the water tank 1; wherein, the support assembly 2 is equipped with several detachable grid plates 3, which divide the inside of the water tank 1 into several seedling trays for cultivating seed seedlings, and a set of seed carrying components 5 is detachably installed at the top of each seedling tray.

[0033] Among them, such as Figures 5-6As shown, the seed carrier component 5 includes a carrier plate frame 501 and a carrier frame 502 for fixing the seeds. The carrier frame 502 is detachably snapped into the middle of the carrier plate frame 501. Specifically, the carrier plate frame 501 includes a rectangular perforated plate 511. The center of the perforated plate 511 is provided with a mounting hole 513 for assembling the carrier frame 502, and a positioning ring 514 is provided around the edge of the mounting hole 513. The perforated design of the carrier plate frame 501 facilitates the removal of the seed carrier component 5 from each seedling trough by the staff, and also facilitates the projection of light to help the seedling root development during hydroponics. It also makes it convenient for the staff to observe the seedling root development in real time. The positioning ring 514 around the mounting hole 513 can play a positioning role for the split-design carrier frame 502.

[0034] To facilitate the removal of oak seedlings from the seedling tray during later transplanting, the support frame 502 adopts a split design. The support frame 502 is generally circular and includes three interlocking arc-shaped locking edges 521. It should be noted that, to improve stability when the three locking edges 521 are interlocked, magnetic fixing or ordinary buckles and slots can be used to achieve quick disassembly and quick assembly.

[0035] After the three clips are spliced ​​together, they form a ring structure that fits into the mounting hole 513. Each clip has several support parts 522 that are equidistantly formed at the bottom and inclined toward the center of the mounting hole 513. Each support part 522 has a clamping part 523 that is set in the opposite direction at the bottom. Both the support part 522 and the clamping part 523 are narrow strips. The transition between the clamping part 523 and the support part 522 is designed with a vertical angle, so that after the three clips are spliced ​​together, the transition between the clamping part 523 and the support part 522 forms a bowl-shaped groove for placing and fixing the oak seeds.

[0036] The design of the support part 522 and the clamping part 523 in the carrier frame 502 makes the enclosed seed fixing groove highly elastic, so it can be adapted to the placement of seeds of different sizes.

[0037] like Figures 1-2 As shown, since the culture medium needs to be changed regularly according to the cultivation stage during the hydroponic cultivation of oak seeds, the water tank 1 is designed as a square box to facilitate the operator to change the nutrient solution in the water tank 1. The water tank 1 is provided with an inlet 7 with a water valve switch and an outlet 6 on the top and bottom of the side of the water tank 1, respectively.

[0038] like Figures 1-2As shown, in order to facilitate the installation and disassembly of the support component 2 and the seed carrying component 5, bracket slots 102 for engaging the support component 2 are provided on the four edges of the top of the water tank 1. At the same time, bracket slots 101 are provided on the four edges of the top of the water tank 1 corresponding to the seedling trough. Each bracket slot 101 is engaged with a side bracket 4 for engaging the seed carrying component 5 with the grid plate 3.

[0039] Among them, such as Figure 3 As shown, the support assembly 2 specifically includes several horizontal frames 201 and several vertical frames 202. The several horizontal frames 201 and several vertical frames 202 are detachably snapped together by wedges 203. On the horizontal frames 201 and vertical frames 202 of the support assembly 2, a through slot 204 for inserting the grid plate 3 is opened at the edge of each seedling trough. At the top of the horizontal frames 201 and vertical frames 202, a positioning notch 205 is opened at both ends of each through slot 204. The ends of the horizontal frames 201 and vertical frames 202 are respectively snapped into the bracket slot 102 on the edge of the water tank 1.

[0040] To ensure that each seedling tray inside water tank 1 is interconnected, facilitating the drainage of nutrient solution or the addition of new nutrient solution, such as... Figure 4 As shown, the grating plate 3 includes a rectangular grating body 301, and the entire grating body 301 is a hollowed-out grid design. At the same time, in order to facilitate the placement of the seed carrying component 5 on the top of each corresponding seedling trough, an "L"-shaped carrying bracket 302 is integrally formed on both sides of the top of the grating body 301 at the position corresponding to the positioning notch 205. The carrying bracket 302 and the side bracket 4 have the same structure and are at the same horizontal height. Positioning slots 303 are opened on the edge of the support platform of the carrying bracket 302 and the side bracket 4. At the same time, a positioning block 512 is integrally formed on the edge of the hollow plate 511 in the carrier frame 501, which engages with the positioning slot 303. The hollow plate 511 is placed flat on the carrying bracket 302 and the side bracket 4 set on the top of the corresponding seedling trough (Note: The carrier frame 501 located in the middle of the water tank 1 is installed using the carrying bracket 302 on the grating plate 3).

[0041] To minimize the overall structural weight and facilitate repeated recycling, the water tank 1, support components 2, grating 3, side brackets 4, and seed-bearing components 5 are all made of plastic. Furthermore, considering the relatively well-developed root systems of oak seedlings, the water tank 1 is 25-40 cm deep to provide ample space for root development, with the appropriate depth selected based on the oak species. Additionally, since most oak species used in landscaping and greening are broadleaf trees, each seedling trough features a square rim with sides of 10-15 cm to ensure sufficient development space for each seedling.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
