Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling technology, and in particular to a seed seedling tray. Background Technology

[0002] As a core piece of equipment for modern agricultural seedling cultivation, the seed and seedling tray provides an independent and controllable cultivation space for seed germination and seedling growth. Through the integrated design of multiple seedling holes, it realizes "single hole, single seedling" cultivation, which facilitates the reduction of root damage and improves the survival rate during subsequent transplanting.

[0003] Currently, existing seedling trays are widely used in greenhouse planting, home gardening, seedling bases and other scenarios. For example, a seed cultivation tray for agricultural seedling cultivation with patent application number 202120547092.0 has several neatly arranged seedling holes for sowing and growth of seeds. However, this design structure is difficult to use in the seedling removal process. Taking conventional methods such as digging with fingers, prying with tools, or shaking off the seedlings by inverting them as examples, these methods are prone to causing soil to break up and root system to break. After the seedling roots are damaged, the seedlings recover slowly after transplanting and the survival rate drops significantly, which is especially significant for vegetable seedlings with fragile root systems. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a seed propagation method.

[0005] The technical solution to the technical problem solved by this utility model is as follows: This utility model proposes a seedling tray, including a tray body formed by connecting several seedling holes; a tray is placed at the bottom of the seedling hole, and pull ropes are connected to both sides of the tray to pull the tray out of the seedling hole; a groove for accommodating the pull rope is opened on the seedling hole, and when the pull rope is placed in the groove, the top end face of the seedling hole forms an unobstructed planar structure.

[0006] Preferably, the seedling hole includes a cone-shaped hole cylinder with a limiting edge fixed at the bottom. The tray is placed on the limiting edge, and a top edge is fixed above the hole cylinder. The placement groove is formed on the upper wall and the top edge of the hole cylinder.

[0007] Preferably, the pull rope has a U-shaped structure, with the connecting end of the pull rope located inside the cavity, and the pulling end of the pull rope placed horizontally in the placement groove.

[0008] Preferably, a disassembly notch is provided on one side of the placement groove, and several sets of locking blocks are fixed on the inner wall of the placement groove to restrain the pull rope within the limiting groove.

[0009] Preferably, the tray has several sets of drainage holes.

[0010] Preferably, a disk frame is fixed on each side of the disk body, and a scraper that can slide linearly is provided inside the disk frame.

[0011] Preferably, the scraper has sowing channels corresponding to the seedling holes, and the inner wall of the sowing channels gradually narrows downward along the vertical axis.

[0012] Preferably, guide rails are provided on the two opposite inner walls of the disk frame, and guide blocks are connected to the two side walls of the scraper, with the guide blocks sliding linearly along the guide rails.

[0013] Preferably, the bottom of the tray frame is fixed with several sets of reinforcing ribs, which are connected to the bottom of the seedling hole.

[0014] Preferably, the outer wall of the tray frame is fixed with a first retaining edge; it also includes an immersion basin, the inner wall of which is provided with a second retaining edge, and when the tray frame is placed in the immersion basin, the second retaining edge can support the first retaining edge.

[0015] The above technical solution has the following advantages or beneficial effects: 1. In this utility model, the substrate and seedlings are directly supported by a tray. When taking the seedlings, it is only necessary to pull the ropes on both sides to remove the tray, substrate and seedlings as a whole from the seedling hole. This operation does not involve any external force contacting the roots or substrate, completely avoiding problems such as root breakage and soil scattering. It can significantly shorten the seedling transfer time and significantly improve the survival rate.

[0016] 2. In this utility model, a linearly movable scraper is provided above the disc body. The scraper has a sowing channel for sowing. The scraper is designed to have the dual attributes of a leveling tool and a sowing mold. When the scraper is pushed, the bottom surface of the scraper first completes the substrate leveling. Then the scraper is moved to the corresponding position and the seeds are placed into the sowing channel. Attached Figure Description

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figure 1 or Figure 6As shown, this embodiment proposes a seedling tray, which includes a tray body 1. The tray body 1 is formed by connecting several sets of seedling holes 3 to form an integral structure. A tray 4 is placed at the bottom of the seedling holes 3, and pull ropes 5 are connected to both sides of the tray 4, which can pull the tray 4 out of the seedling holes 3. In specific applications, when the seedlings in the seedling holes 3 grow to the stage where they need to be transplanted, they can be moved to a more open cultivation environment. The pull ropes 5 on both sides of the tray 4 can be pulled upwards, and the tray 4, the soil above it, and the seedlings can be taken out of the seedling holes 3 together. The operation is convenient and efficient. In addition, the upper part of the seedling holes 3 is provided with a placement groove 6 for accommodating the pull ropes 5. When the pull ropes 5 are placed in the placement groove 6, the pull ropes 5 do not protrude from the top end face of the seedling holes 3, thereby forming an unobstructed planar structure at the top end face of the seedling holes 3.

[0029] Most existing seedling trays lack a dedicated seedling removal structure. Seedlings are usually removed by digging with fingers, prying with tools, or shaking them upside down. This method of removing seedlings can easily lead to soil clumps breaking and root breakage. After the seedling roots are damaged, the seedlings recover slowly after transplanting and the survival rate drops significantly, especially affecting vegetable seedlings with fragile root systems.

[0030] The design disclosed in this application uses a tray 4 to directly support the substrate and seedlings. When taking seedlings out, simply pull the two side ropes 5 to lift the tray 4, substrate, and seedlings out of the seedling hole 3 as a whole. This operation does not involve any external force contacting the roots or substrate, completely avoiding problems such as root breakage and soil scattering. It can significantly shorten the seedling transfer time and significantly improve the survival rate.

[0031] Furthermore, the design of the placement slot 6 ensures that the pull rope 5 does not protrude from the top end face of the seedling hole 3, so as not to interfere with the early stage of the scraper 10 leveling the substrate, nor to occupy the space of the seedling hole 3, thus achieving seamless compatibility between the seedling taking function and the seedling raising function.

[0032] refer to Figure 1 and Figure 2 In some embodiments, the seedling hole 3 includes a cone-shaped hole cylinder 31. A limiting edge 32 is fixed at the bottom of the hole cylinder 31, and the tray 4 is placed on the limiting edge 32. A top edge 33 is fixed above the hole cylinder 31. The top edge 33 has a square structure, which allows several seedling holes 3 to be closely connected to form an integral tray body 1. The placement groove 6 is formed between the upper wall of the hole cylinder 31 and the top edge 33, so that the pull rope 5 can form the above-mentioned "hidden" structure, which facilitates the subsequent operation of the scraper 10 to level the substrate.

[0033] In some embodiments, the pull rope 5 has a U-shaped structure, with the connecting section of the pull rope 5 located inside the seedling tray 31, and the pulling end of the pull rope 5 placed horizontally in the placement groove 6. With this design, when removing seedlings, pulling upwards on both sides applies a uniform pulling force to both sides of the tray 4 simultaneously, preventing problems such as tilting of the tray 4, substrate leakage, or seedling displacement during the upward pulling process, further reducing the risk of root damage. The U-shaped pull rope 5 on both sides can constrain the substrate around the tray 4 during lifting, forming a basket-like structure that facilitates its transfer.

[0034] Furthermore, a disassembly notch 7 is provided on one side of the placement groove 6, through which a finger can be inserted to lift the pull rope 5. During routine movement of the seedling tray, substrate filling, or leveling of the scraper 10, the pull rope 5 is prone to coming out of the placement groove 6 due to vibration or external force; however, the locking block 8 can lock the pull rope 5 tightly in the placement groove 6, preventing the pull rope 5 from protruding from the top of the seedling hole 3, thus not interfering with the leveling of the scraper 10, nor being broken due to the pull rope 5 being exposed, ensuring the positional stability of the pull rope 5 throughout the entire seedling cycle.

[0035] In some embodiments, the tray 4 is provided with several sets of drainage holes 9. When overwatering occurs, excess water can be drained through the drainage holes 9 to prevent root rot and other problems. While serving the drainage function, it can also form an air exchange channel to maintain sufficient oxygen content in the substrate. On the other hand, during the soaking process, water can be absorbed into the substrate in the seedling hole 3 through the drainage holes 9.

[0036] Among them, the pull rope 5 is made of polypropylene fiber rope. This material itself does not absorb water. When soaked in the moist environment of the substrate for a long time, it will not cause mold growth or fiber decomposition due to water absorption, unlike cotton rope and hemp rope. It is also odorless, does not release harmful substances, and has a certain strength, which meets the environmental protection requirements of horticultural seedling cultivation and is suitable for large-scale batch use of seedling trays.

[0037] refer to Figures 3 to 5 In some embodiments, a frame 2 is fixed to each side of the disk body 1. The top surface of the frame 2 extends upward and protrudes from the top surface of the disk body 1, while the bottom surface of the frame 2 is flush with the bottom surface of the disk body 1. A linearly movable scraper 10 is provided inside the frame 2. Specifically, elongated guide rails 12 are respectively provided on the two opposite inner walls of the frame 2. Guide blocks 13 are detachably connected to the two side walls of the scraper 10. The specific disassembly method can be plug-in or bolt connection, etc. The guide blocks 13 can slide linearly along the guide rails 12. The guide blocks 13 and the guide rails 12 adopt a transition fit. This fit allows a stable preset distance to be formed between the bottom surface of the scraper 10 and the top surface of the disk body 1. This preset distance is usually 0.5-1mm, which can avoid hard contact between the scraper 10 and the top surface of the disk body 1 when sliding, and reduce frictional wear between the two.

[0038] With the coordinated operation of the guide rail 12 and guide block 13, problems such as left-right deviation or tilting scraping that are easy to occur when manually operating the traditional guideless scraper 10 are avoided. The scraper 10 has a consistent movement trajectory, which can ensure that the substrate at the top of all seedling holes 3 is evenly scraped and leveled, and there will be no situation where the substrate in some holes is too thick and some is too thin.

[0039] In some embodiments, the scraper 10 has sowing channels 11 corresponding to the seedling holes 3, and the inner wall of the sowing channels 11 gradually narrows downward along the vertical axis. The scraper 10 can serve as both a leveling tool and a sowing mold. When the scraper 10 is pushed, the bottom surface of the scraper 10 first levels the substrate, and then the scraper 10 is moved to the corresponding position to place the seeds into the sowing channels 11.

[0040] Compared to the traditional manual sowing process of "manually leveling the substrate, positioning each seedling hole 3, and manually sowing seeds," which is not only cumbersome but also prone to seed misalignment due to visual bias or hand tremors, this design achieves functional reuse through the scraper 10, realizing integrated leveling and sowing operations, effectively improving sowing efficiency and accuracy.

[0041] To further ensure that the sowing channel 11 is accurately aligned with the center of the seedling hole 3 after the scraper 10 moves, markings are set on the side of the tray frame 2 and on the scraper 10. When the marking on the scraper 10 is aligned with one of the markings on the side of the tray frame 2, the center of the sowing channel 11 can be aligned with the center of several seedling holes 3 in that row, and then the subsequent sowing work can be carried out.

[0042] In some embodiments, a plurality of reinforcing ribs 14 are fixed to the bottom of the tray frame 2. The reinforcing ribs 14 are connected to the bottom of the seedling hole 3, and the width of the reinforcing ribs 14 is smaller than the diameter of the bottom surface of the seedling hole 3. During operations such as handling and weighing the seedling tray, it needs to withstand multiple external forces. The reinforcing ribs 14 establish a connection between the tray frame 2 and the seedling hole 3, integrating the dispersed stress points into an overall stress-bearing frame, effectively solving the problem of localized deformation in traditional seedling trays.

[0043] refer to Figure 6 In some embodiments, a first retaining edge 15 is fixed to the outer wall of the tray frame 2; a soaking basin 16 is also provided, and a second retaining edge 17 is provided on the inner wall of the soaking basin 16. When the tray frame 2 is placed in the soaking basin 16, the second retaining edge 17 can support the first retaining edge 15. The seedling tray is placed into the soaking basin 16 and positioned by means of the first retaining edge 15 and the second retaining edge 17, so that the bottom of the tray 1 is placed in the water in the soaking basin 16, and water is replenished from bottom to top by the tray 4.

[0044] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
