Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling equipment technology, and in particular to a multi-layer stacked seedling tray. Background Technology

[0002] In traditional agricultural seedling cultivation, single-layer seedling trays are difficult to meet the needs of large-scale seedling production due to their low space utilization and large site occupation. The emergence of multi-layer stackable seedling trays has effectively solved the space problem, significantly increasing the number of seedlings per unit area by stacking them layer by layer.

[0003] However, existing multi-layer seedling trays generally suffer from fixed interlayer spacing, making it impossible to flexibly adjust according to seedling height. This limits ventilation and light conditions, negatively impacting seedling growth quality. Furthermore, traditional designs have simple drainage structures, allowing water from the upper trays to drip directly to the lower ones, easily leading to overwatering and even root rot in the lower seedlings. The lack of effective drainage further complicates water management. Therefore, there is an urgent need for a new type of multi-layer seedling tray with adjustable interlayer spacing and excellent drainage capabilities to optimize the seedling environment and improve seedling efficiency. Utility Model Content

[0004] In view of this, the present invention aims to provide a multi-layer stackable seedling tray to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the accompanying drawings and specific circumstances.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1-7 The present invention provides a multi-layer stackable seedling tray, including a main frame 1 with an open top, and further including: a lifting and locking assembly 2 for lifting and locking the seedling tray; and a drainage and guiding assembly 3 for guiding the water discharged from the seedling tray. The lifting and locking assembly 2 includes longitudinally formed grooves 4 on the four side columns of the main frame 1 and sliders 5 slidably connected to the four grooves 4, and a lifting frame 6 fixed to the sliders 5. The lifting frame 6 has a slot 7 at its bottom, on which a seedling tray 8 is placed. Vertical grooves 9 are formed on the outer sides of the two obliquely symmetrical grooves 4. A screw 10 threaded through the vertical grooves 9 and the sliders 5 is also included, with a knob 11 fixed to the end of the screw 10. The drainage and guiding assembly 3 includes seedling holes 12 evenly distributed on the seedling tray 8 and drainage holes 13 evenly distributed at the bottom of the seedling holes 12. A water receiving tray 14 is obliquely fixed to the bottom of the lifting frame 6, and the water receiving tray 14 is located directly below the drainage holes 13.

[0038] In this embodiment, specifically, the tilt angle of the water receiving tray 14 is 15°, and an anti-slip pad 15 is provided between the lifting frame 6 and the seedling tray 8.

[0039] In this embodiment, specifically, it also includes a movable component 16, which includes a support frame 17. The support frame 17 is symmetrically connected to the bottom of the main frame 1 by bolts 18, and self-locking casters 19 are symmetrically provided at the bottom of the support frame 17.

[0040] In this embodiment, specifically, the slide groove 4 and the slider 5 have trapezoidal cross sections to limit movement. The screw 10 is fitted with a protective pad 20. The water receiving tray 14 is made of plastic with a smooth surface. The sliding connection between the slider 5 and the slide groove 4 is a clearance fit. The slide groove 4 is provided with a lubricating layer. Another set of two obliquely symmetrical slide grooves 4 are vertically fixed with slide rods 21, which pass through the slider 5.

[0041] When this utility model is in operation: when it is necessary to adjust the spacing of the lifting frame 6, first rotate the knob 11. The knob 11 drives the screw 10 to rotate, resulting in a relaxed state. Then, lift the lifting frame 6 with both hands. At this time, the slider 5 slides upward along the slide groove 4. When it reaches the appropriate position, rotate the knob 11 in the opposite direction so that the knob 11 fits against the outer side of the side column of the main frame 1. The protective pad 20 plays a protective role. During the seedling process, the water accumulated in the upper seedling tray 8 flows into the water receiving tray 14 through the drainage hole 13 and is discharged along the inclined surface to prevent the lower seedlings from being soaked. When it is necessary to move the device, the moving component 16 can be installed. The user can slide the slider 5 downward in the slide groove 4 according to the actual needs, which can realize the superimposed installation of the lifting frame 6 and the seedling tray 8.

[0042] In summary, this device uses the rotating knob 11 to drive the screw 10 to relax, while simultaneously raising the lifting frame 6, achieving stepless height adjustment to meet the space requirements of seedlings at different growth stages. The water receiving tray 14 is tilted and extends to the outside of the main frame 1, allowing the water accumulated in the upper seedling tray 8 to flow into the water receiving tray 14 through the drainage hole 13 and be discharged along the inclined surface, preventing it from dripping onto the lower seedlings. This solves the problems of the existing technology, such as the inability to adjust the seedling spacing and the lack of a flow guiding structure.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
