Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to an agricultural planting seedling tray. Background Technology

[0002] As a core tool in modern horticulture and industrialized agricultural production, the technological evolution and material innovation of agricultural seedling trays profoundly affect the efficiency and quality of seedling production. Traditional seedling trays are made of materials such as polystyrene and polyvinyl chloride, and achieve seed positioning and substrate fixation through standardized holes (540mm×280mm, number of holes 18-800).

[0003] Because plants have different living habits, different seedling methods can be used for different plants. Commonly used seedling methods include nutrient block seedling method, nutrient bag seedling method, and floating seedling method. Among them, the floating seedling method involves floating seedling trays filled with lightweight seedling substrate on the water surface. However, due to the varying weight of the substrate added to the seedling cavity, the depth of the seedling tray submerged below the water surface is often uncontrollable. This can easily lead to the seedlings being completely submerged below the water surface, causing long-term oxygen deficiency and drowning of the seedlings. Utility Model Content

[0004] The purpose of this utility model is to provide an agricultural seedling tray to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an agricultural planting seedling tray, including a pressure plate, a tray and multiple seedling unit boxes. The pressure plate and the tray are provided with multiple openings distributed in a matrix structure. The upper end of the seedling unit box has an enlarged step extending laterally. The seedling unit box is inserted into the opening of the tray, and the enlarged step is located on the upper end surface of the tray. The tray is detachably installed below the pressure plate, and the enlarged step is fixedly clamped between the pressure plate and the tray.

[0006] A hollow bottom frame is positioned directly below the tray, and multiple cylindrical floats are provided on the hollow bottom frame to provide buoyancy and suspend multiple seedling unit boxes on the liquid surface.

[0007] In a further embodiment, elastic buckles are fixed on both sides of the upper surface of the tray, and notches are opened on both opposite sides of the pressure plate. The two elastic buckles are opened to allow the pressure plate to sit on the upper surface of the enlarged step of the multiple seedling unit boxes. Then, the two elastic buckles are released, and the ends of the elastic buckles pass through the notches and are locked on the upper surface of the pressure plate.

[0008] In a further embodiment, the seedling unit box is larger at the top and smaller at the bottom, and ventilation holes are provided at the bottom and side walls of the seedling unit box.

[0009] In a further embodiment, the seedling unit box is made of rubber.

[0010] In a further embodiment, each of the four corners of the upper surface of the hollow bottom frame is fixedly provided with a hanging rod, and the upper end of the hanging rod is fixedly connected to the corner of the bottom wall of the support plate;

[0011] The height of the boom is greater than the height of the seedling unit box.

[0012] In a further embodiment, a plurality of insertion holes are provided on one long side wall of the hollow bottom frame, and a threaded groove distributed coaxially with the insertion holes is provided on the other long side wall. The end of the cylindrical float slides through the insertion hole and is threadedly connected to the threaded groove.

[0013] In a further embodiment, the cylindrical float has a closed structure, and a protrusion is provided at one end of the cylindrical float located at the insertion hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model is an agricultural planting seedling tray. It provides buoyancy through multiple cylindrical floats to suspend multiple seedling unit boxes on the liquid surface. This not only ensures that the seedlings absorb nutrients during the seedling cultivation process, but also solves the problem of seedlings drowning due to long-term oxygen deficiency caused by excessive substrate added to multiple seedling unit boxes, which would completely submerge the seedlings below the liquid surface.

[0016] 2. The enlarged step of the seedling unit box of this utility model is clamped and fixed between the pressure plate and the tray, so as to realize the fixed installation of multiple seedling unit boxes. In addition, if individual seedling unit boxes are damaged, the damaged seedling unit boxes can be removed and replaced by disassembling the pressure plate and the tray, thus avoiding the need to replace the entire seedling tray due to the damage of individual seedling unit boxes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This embodiment provides an agricultural seedling tray, such as... Figure 1 and Figure 4 As shown, it includes a pressing plate 1, a tray 2, and multiple seedling unit boxes 3. Both the pressing plate 1 and the tray 2 have multiple openings distributed in a matrix structure. The upper end of the seedling unit box 3 has an enlarged step extending laterally.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, elastic buckles 21 are fixed on both sides of the upper end face of the tray 2. Notches are opened on both opposite side walls of the pressure plate 1. The seedling unit box 3 is inserted into the opening of the tray 2, with the enlarged step resting on the upper end face of the tray 2. The two elastic buckles 21 are opened, and the pressure plate 1 is placed on the upper end face of the enlarged step of the multiple seedling unit boxes 3. Then, the two opened elastic buckles 21 are released, and the elastic buckles 21 return to their original position. The ends of the elastic buckles 21 pass through the notches and lock onto the upper end face of the pressure plate 1, thus fixing the enlarged step between the pressure plate 1 and the tray 2. Through the mechanical locking of the elastic buckles 21, it is ensured that the pressure plate 1 and the tray 2 tightly clamp the seedling unit box 3, preventing displacement of the seedling unit box 3 due to liquid level fluctuations.

[0026] The enlarged step of the seedling unit box 3 is clamped and fixed between the pressure plate 1 and the tray 2, enabling the fixed installation of multiple seedling unit boxes 3. In addition, if any individual seedling unit box 3 is damaged, the pressure plate 1 and the tray 2 can be separated by disassembling them and operating the elastic buckle 21 in reverse. This facilitates the replacement or cleaning of the seedling unit box 3, avoiding the need to replace the entire seedling tray due to damage to a single seedling unit box 3.

[0027] like Figure 5As shown, this embodiment also discloses a hollow bottom frame 4, which is located directly below the tray 2. Hanging rods are fixedly installed at the four corners of the upper surface of the hollow bottom frame 4, and the upper ends of the hanging rods are fixedly connected to the corners of the bottom wall of the tray 2. Multiple cylindrical floats 5 are provided on the hollow bottom frame 4. Multiple insertion holes 41 are opened on one long side wall of the hollow bottom frame 4, and threaded grooves 42 are coaxially distributed with the insertion holes 41 on the other long side wall. The ends of the cylindrical floats 5 slide through the insertion holes 41 and are threadedly connected to the threaded grooves 42. Simultaneously, the cylindrical floats 5 have a closed structure inside, and a protrusion is provided at one end of the cylindrical float 5 located at the insertion hole 41. Pinching the protrusion facilitates the insertion and rotation of the cylindrical float 5. The overall buoyancy can be adjusted by increasing or decreasing the number of cylindrical floats 5 or replacing them with floats of different volumes according to the weight of the substrate in the seedling unit box 3. Furthermore, the cylindrical floats 5 are installed independently, allowing for quick replacement when damaged, reducing maintenance costs.

[0028] Multiple cylindrical floats 5 provide buoyancy, suspending multiple seedling unit boxes 3 on the liquid surface. The buoyancy of the seedling unit boxes 3 is adjusted to maintain their suspension. Combined with the detachable pressure plate 1 and support plate 2 structure, it adapts to the needs of different plants. Meanwhile, the ventilation holes and rubber material optimize the root growth environment. In other words, the buoyancy of the cylindrical floats 5 counteracts the weight of the seedling unit boxes 3 and their internal substrate, ensuring that the bottom of the boxes just touches the liquid surface. This guarantees water absorption while preventing the seedlings from being completely submerged and suffering from oxygen deficiency.

[0029] In summary, by providing buoyancy through multiple cylindrical floats 5, multiple seedling unit boxes 3 are suspended on the liquid surface. This ensures that the seedlings absorb nutrients during the seedling cultivation process and also solves the problem of seedlings drowning due to long-term oxygen deficiency caused by excessive substrate added to multiple seedling unit boxes 3, which would otherwise completely submerge the seedlings below the liquid surface.

[0030] Further clarification is needed, such as Figure 3 As shown, the seedling unit box 3 is wider at the top and narrower at the bottom, and ventilation holes are provided at the bottom and on both the side walls. The ventilation holes at the bottom facilitate the immersion of nutrient solution into the seedling unit box 3, meeting the needs of seedling root absorption. The ventilation holes on the side walls are for aeration, allowing the seedling roots to perform aerobic respiration. The ventilation holes on the side walls promote air circulation and prevent root rot.

[0031] The height of the boom is greater than the height of the seedling unit box 3 to prevent the bottom wall of the seedling unit box 3 from extending into the hollow bottom frame 4, which would affect the installation of the cylindrical float 5. At the same time, it ensures that the hollow bottom frame 4 is completely submerged in the liquid, while the bottom of the seedling unit box 3 is suspended on the liquid surface.

[0032] Seedling unit box 3 is made of rubber. The rubber material is shockproof to reduce wear on the box body, while its elastic deformation can adapt to different substrate filling amounts.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
