Description

Technical Field

[0001] This utility model relates to the field of vegetable seedling technology, and in particular to a vegetable seedling tray with adjustable spacing. Background Technology

[0002] Vegetable seedling raising is a crucial step in vegetable production. It refers to the process of cultivating robust and uniform seedlings in seedbeds or plug trays under artificially controlled conditions such as light, temperature, and humidity before transplanting them to the field. It typically includes steps such as seed disinfection, seed soaking and germination, sowing, and seedling management. Seedling raising can effectively improve seed survival rate, reduce pests and diseases, shorten the crop growth cycle, and advance the market time. Common seedling raising methods include open-field seedling raising, nutrient pot seedling raising, plug tray seedling raising, and modern greenhouse seedling raising. Among them, plug tray seedling raising is widely used because it saves space and is easy to manage. Scientific seedling raising can lay a solid foundation for high-yield and high-quality vegetables.

[0003] A search revealed that the document with publication number "CN218977438U" states that "this utility model discloses a vegetable seedling tray, including a seedling tray body, storage compartments, a structural frame, a shaft, gears, connectors, movable parts, round blocks, limiting frames, limiting blocks, toothed columns, connecting rods, support rods, and a base plate. The storage compartments are located inside the seedling tray body, and there are several storage compartments evenly distributed inside the seedling tray body. The structural frame is connected to both sides of the bottom of the seedling tray body, the shaft is connected to the front and rear sides of the inner wall of the structural frame, the gear is sleeved on the surface of the shaft and located inside the structural frame, and the connector is sleeved on the surface of the shaft and connected to the gear." In use, this invention solves the problem that existing seedling trays are integrally formed, and because vegetable seedling roots are often covered with a large amount of soil inside the seedling compartment, pulling up the seedlings increases the weight of the roots and easily damages them, thus causing inconvenience to the user.

[0004] However, the spacing of traditional vegetable seedling trays is not adjustable, which leads to seedlings being too close together during their growth, blocking sunlight and affecting production. In addition, when planting different varieties of vegetables, different sizes of seedling trays are needed because different varieties of seedlings require different spacing. Furthermore, when adjusting the seedling trays, soil and other debris can easily enter the adjustment track, affecting the adjustment effect.

[0005] Therefore, we provide a vegetable seedling tray with adjustable spacing to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides an adjustable spacing vegetable seedling tray, which aims to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An adjustable-spacing vegetable seedling tray includes a base frame. An adjustment assembly is installed on the upper side of the base frame. The adjustment assembly includes a guide rail installed on the upper side of the base frame, a slider installed on the upper side of the guide rail, a tensioning knob installed on the outer side of the slider, a connecting block connected to the upper side of the slider, a support rod connected to the middle of the connecting block, a groove provided on the lower side of the support rod, a seedling trough connected to the lower side of the groove, T-shaped frames installed on both sides of the seedling trough, a drainage hole provided at the lower end of the seedling trough, a fixing block connected to the upper side of the seedling trough, and a fixing knob installed on the upper side of the fixing block.

[0008] As a further description of the above technical solution: The guide rail and the slider are connected by a sliding groove. The connecting block and the guide rail form a left-right sliding structure through the slider. The slider is fixed by a tightening knob.

[0009] As a further description of the above technical solution: A protective cover is connected between the sliders. The protective cover is a telescopic structure that can extend and retract as the sliders move.

[0010] As a further description of the above technical solution: The support rod and the connecting block are connected by a slot, and the slide groove is opened inside the lower side of the support rod. The slide groove has a T-shaped structure.

[0011] As a further description of the above technical solution: The seedling trough is welded with T-shaped frames on both the left and right sides. The seedling trough is connected to the support rod by a sliding groove through the T-shaped frame. The seedling trough is fastened by a fixing block and a fixing knob.

[0012] As a further description of the above technical solution: The inner side of the seedling trough is an inverted cone shape, and a circular drainage hole is provided at the bottom of the seedling trough.

[0013] As a further description of the above technical solution: The connecting block and the slider are connected by bolts, and the support rod and the connecting block can be replaced.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up an adjustment component, sliding a slider on the guide rail moves the seedling troughs on the connecting block and support rod left and right, allowing for adjustable lateral spacing between different rows of seedling troughs. This prevents seedlings from crowding each other and competing for light as they grow, resulting in thin and weak stems. It also eliminates the need to change to different sizes of fixed seedling trays when planting different vegetable varieties. After adjustment, tightening the adjustment knob secures the tray and prevents lateral movement of the slider. A retractable protective cover protects the guide rail without affecting the slider's movement, preventing foreign objects from entering the guide rail when adding soil to the seedling troughs and damaging the slider. To prevent the slide block from causing problems, a groove is created inside the lower side of the support rod to prevent foreign objects from entering the groove when adding soil or watering the seedling trough, thus avoiding affecting the slide. At the same time, the T-shaped groove fits into the T-shaped frames on the left and right sides of the seedling trough, ensuring the seedling trough is fixed and stable and preventing lateral swaying. By moving the T-shaped frames on the left and right sides of the seedling trough back and forth on the groove, the seedling trough can be adjusted back and forth, allowing the spacing between individual seedling troughs to be adjustable. This further prevents the spacing between seedling troughs from being too small, which would affect seedling growth. After adjustment, the fixing knob on the static fixing block is used to tighten it and prevent the seedling trough from moving.

[0015] 2. By setting up seedling trays and drainage holes, the seedling trays with an inverted conical inner side promote air pruning of roots, prevent root rot, and facilitate the removal of seedlings while ensuring the integrity of the root ball. At the same time, drainage holes prevent water accumulation at the seedling roots and improve root aeration. By removing bolts, support rods with different spacing and seedling trays of different specifications can be replaced to adapt to the different growth needs of vegetables and improve applicability.

[0018] 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.

[0019] Please see Figure 1-4 As shown, this utility model provides a technical solution: an adjustable spacing vegetable seedling tray, including a base frame 1, an adjustment component 2 installed on the upper side of the base frame 1, the adjustment component 2 including a guide rail 201 installed on the upper side of the base frame 1, a slider 202 installed on the upper side of the guide rail 201, a tightening knob 203 installed on the outer side of the slider 202, a connecting block 205 connected to the upper side of the slider 202, a support rod 206 connected to the middle of the connecting block 205, a sliding groove 207 provided on the lower side of the support rod 206, a seedling trough 3 connected to the lower side of the sliding groove 207, T-shaped frames 4 installed on both the left and right sides of the seedling trough 3, a drainage hole 5 provided at the lower end of the seedling trough 3, a fixing block 6 connected to the upper side of the seedling trough 3, and a fixing knob 7 installed on the upper side of the fixing block 6.

[0020] Furthermore, the guide rail 201 and the slider 202 are connected by a sliding groove. The connecting block 205 and the guide rail 201 form a left-right sliding structure through the slider 202. The slider 202 is fixed by the tightening knob 203. By sliding the slider 202 on the guide rail 201, the seedling troughs 3 on the connecting block 205 and the support rod 206 are moved left and right, so that the left and right spacing between different rows of seedling troughs 3 can be adjusted. This avoids the seedlings in the seedling troughs 3 from crowding each other and competing for light after they grow up, resulting in thin and weak stems. At the same time, it avoids the need to change the fixed seedling trays of different specifications when planting different varieties of vegetables. After adjustment, the slider 202 is fixed by tightening the tightening knob 203 to prevent the slider 202 from moving sideways.

[0021] Furthermore, a protective cover 204 is connected between the sliders 202. The protective cover 204 is a telescopic structure that can extend and retract as the sliders 202 move. By setting the telescopic protective cover 204, the guide rail 201 is protected without affecting the movement of the sliders 202, thus preventing foreign objects from entering the guide rail 201 when adding soil to the seedling trough 3, which would affect the sliding of the sliders 202.

[0022] Furthermore, the support rod 206 and the connecting block 205 are connected by a slot, and the slide groove 207 is opened inside the lower side of the support rod 206. The slide groove 207 has a T-shaped structure. By opening the slide groove 207 inside the lower side of the support rod 206, foreign objects are prevented from entering the slide groove 207 when adding soil or watering the seedling trough 3, which would affect the sliding. At the same time, the T-shaped slide groove 207 fits into the T-shaped frame 4 on the left and right sides of the seedling trough 3, ensuring that the seedling trough 3 is fixed and stable, and preventing left and right swaying.

[0023] Furthermore, T-shaped frames 4 are welded to the left and right sides of the seedling trough 3. The seedling trough 3 is connected to the slide groove 207 on the lower side of the support rod 206 via the T-shaped frames 4. The seedling trough 3 is secured by the fixing block 6 and the fixing knob 7. The T-shaped frames 4 on the left and right sides of the seedling trough 3 move back and forth on the slide groove 207, thereby adjusting the seedling trough 3 back and forth. This allows the spacing between individual seedling troughs 3 to be adjustable, further preventing the spacing between seedling troughs 3 from being too small and affecting seedling growth. After adjustment, the seedling trough 3 is secured by the fixing knob 7 on the fixing block 6 to prevent it from moving.

[0024] Furthermore, the inner side of the seedling trough 3 is an inverted cone-shaped structure, and a circular drainage hole 5 is provided at the bottom of the seedling trough 3. By setting the seedling trough 3 with an inverted cone-shaped inner side, air pruning of roots is promoted, root rot is prevented, and seedlings are easy to remove, ensuring the integrity of the root ball. At the same time, the drainage hole 5 is provided to prevent water accumulation in the seedling roots and improve root aeration.

[0025] Furthermore, the connecting block 205 and the slider 202 are connected by bolts, and the support rod 206 and the connecting block 205 can be replaced. By removing the bolts, support rods 206 with different spacing and seedling troughs 3 of different specifications can be replaced to adapt to different vegetable growth needs and improve applicability.

[0026] Working principle: In use, several seedling troughs 3 are connected to the sliding grooves 207 on the lower side of the support rod 206 via the T-shaped frames 4 on the left and right sides. Then, the support rod 206 is connected to the connecting block 205 in a slotted manner. The connecting block 205 is fixed by bolts and sliders 202. By moving the sliders 202 on the guide rails 201 on the base frame 1, the spacing between each row of seedling troughs 3 is adjusted to a suitable distance. The tightening knob 203 is tightened to fix it. At the same time, the protective covers 204 between the sliders 202 protect the guide rails 201 to prevent soil from entering the guide rails 201. By moving the seedling trays 3 back and forth on the sliding groove 207, the spacing between individual seedling trays 3 can be adjusted to a suitable level. The trays are then fixed by tightening the fixing knobs 7 on the fixing block 6. Meanwhile, the sliding groove 207 on the lower side of the support rod 206 prevents soil from entering and affecting the sliding. The seedling trays 3 with their inverted conical inner sides promote air pruning and prevent root rot, while also facilitating the removal of seedlings and ensuring the integrity of the root ball. Additionally, drainage holes 5 are provided to prevent water accumulation at the seedling roots and improve root aeration. This completes the process of using an adjustable spacing vegetable seedling tray.

[0027] 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.
