Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a seedling-raising device for agricultural cultivation and planting, including a breeding tray, and the breeding tray is composed of two upper seedling trays 4 and lower seedling trays 5 that can be assembled up and down;

[0037] A plurality of seedling cone tubes 6 are integrally formed at the bottom of the upper seedling tray 4. The top of the seedling cone tube 6 is open, and a soil holding net 7 for holding the culture medium is installed in the seedling cone tube 6;

[0038] A plurality of seed soaking grooves 10 corresponding to the seedling cone tubes 6 are opened at the top of the lower seedling tray 5. When the upper seedling tray 4 and the lower seedling tray 5 are assembled, the bottom of the seed soaking groove 10 and the inner wall of the seedling cone tube 6 together form a seedling-raising cup structure for raising seedlings;

[0039] It further includes a puncturing part arranged in the lower seedling tray 5, and the puncturing part is used to push the seeds in the seed soaking groove 10 upward and break through the mesh holes of the soil holding net 7 until they penetrate into the culture medium in the seedling cone tube 6.

[0040] When the seedling-raising device is in use, first separate the upper seedling-raising tray 4 and the lower seedling-raising tray 5, and then lay the soil-holding net 7 into the seedling-raising conical tube 6 to seal its bottom opening. The soil-holding net 7 can be fixed to the seedling-raising conical tube 6 by simple adhesion to prevent it from shifting. Then, fill the seedling-raising conical tube 6 with a culture medium (such as soil or nutrient soil, etc.), and use the soil-holding net 7 to hold it, initially forming a simple culture cup structure. The soil-holding net 7 can be an existing fiber net, which can not only prevent the culture medium from falling but also has good flexibility and an appropriate pore size, allowing the plant roots to penetrate and grow, and also providing conditions for the subsequent piercing of the seeds;

[0041] Meanwhile, fill the seed soaking tank 10 with a soaking solution, such as water or other special soaking solutions, and then place the seeds in the corresponding seed soaking tanks 10 for soaking. During the soaking process, regularly observe the water absorption situation and soaking progress of the seeds to ensure that the seeds are fully swollen by absorbing water. When the soaking reaches the predetermined time, directly install the prepared upper seedling-raising tray 4 and the lower seedling-raising tray 5 in an up-and-down combination, so that the bottom end of the seedling-raising conical tube 6 enters the seed soaking tank 10 and contacts and abuts against its inner wall, so that the bottom of the seed soaking tank 10 and the inner wall of the seedling-raising conical tube 6 jointly form a seedling-raising cup structure for raising seedlings, as Figure 8 shown. Meanwhile, the piercing part pushes the seeds in the seed soaking tank 10 upward and breaks through the mesh holes of the soil-holding net 7 until they penetrate into the culture medium in the seedling-raising conical tube 6, thus completing the seed planting process. The combined upper seedling-raising tray 4 and the lower seedling-raising tray 5 can be placed on the partition shelf, without occupying too much space;

[0042] When the seedlings grow and need to be transplanted, separate the upper and lower seedling-raising trays again, and then the culture medium wrapped by the soil-holding net 7 and the seedlings can be taken out together to ensure the integrity of the adhesion of the seedling roots and the soil ball, and further ensure the transplant survival rate of the seedlings;

[0043] In this way, through the combination of the upper seedling-raising tray 4 and the lower seedling-raising tray 5, not only can the unified management of the soaking, planting, and seedling-taking processes be realized, the automatic piercing and planting of the seeds after soaking can be achieved, but also the structure is simple and occupies less space. During the long-term use process, it is also convenient for continuous reuse and cleaning after use, which can greatly reduce problems such as loosening, deformation, and damage caused by frequent operations, and improve the normal service life of the device.

[0044] Moreover, it is worth mentioning that the method of sowing seeds by piercing them from below is compared with the traditional method of first placing the seeds and then covering them with soil or substrate. This method can not only precisely control the planting depth of the seeds, directly fix the seeds at specific positions in the soil, and ensure that the seeds are planted according to the optimal depth requirements. Since the suitable planting depths of different crop seeds vary, precise sowing helps to improve the germination rate of the seeds and the growth quality of the seedlings, but also can ensure that the distribution positions of the seeds in the breeding tray or soil are more precise and uniform.

[0045] In one relatively preferred embodiment, an installation structure and implementation method for combining or disassembling and separating the upper seedling tray 4 and the lower seedling tray 5 are provided;

[0046] It further includes a mounting frame. The mounting frame includes a bottom plate 1 and side frames 2 fixed on both sides thereof. Removable top plate frames 3 are installed at the tops of the side frames 2 on both sides. The upper seedling tray 4 and the lower seedling tray 5 are both slidably installed between the side frames 2 on both sides. A second screw rod 9 is rotatably installed at the top of the lower seedling tray 5. The top end of the second screw rod 9 penetrates through the upper seedling tray 4 and the top plate frame 3 and is threadedly connected to the penetration part of the upper seedling tray 4. A first screw rod 8 is rotatably installed between the top plate frame 3 and the bottom plate 1. The first screw rod 8 penetrates through the upper seedling tray 4 and the lower seedling tray 5 and is threadedly connected to the penetration part of the lower seedling tray 5. Knobs are fixed at the top ends of both the first screw rod 8 and the second screw rod 9.

[0047] Specifically, refer to Figures 1 - 3 , by slidably installing the upper seedling tray 4 and the lower seedling tray 5 between the side frames 2 on both sides of the bottom plate 1, vertical sliding limits can be imposed on them, so that when installing or disassembling, the corresponding seedling cone tubes 6 and soaking grooves 10 can be aligned. Secondly, when it is necessary to combine or disassemble the two seedling trays, by rotating the knob to rotate the second screw rod 9, the distance between the upper seedling tray 4 and the lower seedling tray 5 can be adjusted, thereby achieving the purpose of combination or disassembly;

[0048] After the two are combined and installed, by rotating the first screw rod 8, the upper seedling tray 4 and the lower seedling tray 5 can be driven to approach or move away from the bottom plate 1 together, providing conditions for the subsequent piercing of the seeds. Moreover, the penetration method between the second screw rod 9 and the top plate frame 3 allows for vertical sliding adjustment within its through hole without causing interference in the stroke;

[0049] Moreover, the detachable design of the top plate frame 3 can also facilitate the disassembly, replacement, and cleaning of the upper and lower seedling trays, and is convenient for post-transplantation processing.

[0050] In one relatively preferred embodiment, an implementation method of the piercing part is provided;

[0051] The puncturing part includes a puncturing tube 11 fixed to the top of the bottom plate 1 and a core rod 12 slidably installed inside the puncturing tube 11. A through hole for the puncturing tube 11 to pass through is provided at the bottom of the center of the seed soaking tank 10. A long groove is provided on the outer wall of the puncturing tube 11 located inside the through hole. A friction pin 13 that penetrates outside the long groove is fixed to the outer wall of the core rod 12, and the friction pin 13 is in frictional sliding connection with the inner wall of the through hole.

[0052] Specifically, it can be seen from Figures 4 - 5 , a groove for placing seeds is jointly formed at the top of the puncturing tube 11 and the core rod 12, and the top end of the puncturing tube 11 is lower than or flush with the bottom surface of the seed soaking tank 10 in the initial state. This can ensure the soaking of seeds by water. At the same time, the seeds are located inside the puncturing tube 11, which can also prevent the seeds from directly contacting the puncturing tube 11 when it pierces the soil holding net 7, avoiding damage to the seeds.

[0053] During planting, as can be seen from the above, by rotating the first screw rod 8, the two combined seedling trays can be moved together closer to the bottom plate 1. At this time, the puncturing tube 11 fixed to the bottom plate 1 will move upward due to relative movement and pierce into the culture medium through the mesh holes of the soil holding net 7. During this process, the upward movement of the puncturing tube 11 will, through the blocking effect of the long groove on the friction pin 13, enable the puncturing tube 11 and the core rod 12 to maintain Figure 4 the groove state in

[0054] to puncture and transport the seeds upward; Figure 10 As shown in the state of the seeds before and after soaking in water;

[0055] When the puncturing tube 11 moves downward first, the culture medium will fall and fill the position where the puncturing tube 11 is located to also play a certain supporting and limiting role for the seeds. Until the long groove on the puncturing tube 11 comes into contact with the friction pin 13 again, the puncturing tube 11 will drive the core rod 12 to move downward and reset. Subsequently, the culture medium fills the position of the core rod 12, and thus the puncturing planting process of the seeds can be completed;

[0056] In this way, by the sequential withdrawal of the puncturing tube 11 and the core rod 12, it can be avoided that the seeds do not move downward with them, further ensuring the sowing accuracy of the seeds and improving the subsequent seedling raising effect.

[0057] In a relatively preferred embodiment, the top opening of the puncturing tube 11 is set as a flared opening, and the top end of the core rod 12 is provided with a concave surface. See Figure 10, The flared design of the puncture tube 11 and the concave design of the core rod 12 are both for better placement of the seeds and their expansion after absorbing water.

[0058] In one relatively preferred embodiment, the bottom end of the seedling-growing conical tube 6 is provided with wave protrusions, and the through grooves formed between the wave protrusions enable the interior of the formed breeding cup structure to communicate with the seed soaking groove 10. Adjacent seed soaking grooves 10 are connected through a communicating water channel 16 opened in the lower seedling-growing tray 5. Water injection pipes 17 connected to the communicating water channel 16 at the edge positions are connected to both outer walls of the lower seedling-growing tray 5, and the water injection pipes 17 are connected to an external water supply pipeline.

[0059] As can be seen from the above, the seed soaking groove 10 is mainly for soaking the seeds. In order to facilitate the subsequent watering process, by designing the communicating water channel 16 and the water injection pipes 17, not only can water be easily injected into it for soaking the seeds, but also after planting, since the seed soaking groove 10 forms the bottom of the breeding cup structure, when water is injected into the seed soaking groove 10 during the planting stage, the water can contact the culture medium through the through grooves between the wave protrusions, and then under the action of capillary action, the effect of watering from below can be achieved. In this way, the irrigation process can be integrated, further simplifying the seedling-growing process and improving work efficiency.

[0060] In this way, the seed soaking groove 10 can play different roles at different stages, further simplifying the structure, reducing water evaporation, guiding the roots to grow downward, increasing the root coverage rate of the seedlings, and at the same time, by precisely controlling the water injection speed and amount, each breeding cup structure can uniformly obtain the required water, avoiding the possible situation of local over-wetting or over-drying, ensuring the consistency of the seedling growth environment, and being conducive to cultivating uniform and strong seedlings.

[0061] In one relatively preferred embodiment, an implementation method is provided to facilitate the removal of the soil ball and the seedlings from the seedling-growing conical tube 6 during the subsequent transplanting process.

[0062] It further includes a partition plate 14 provided between the upper seedling-growing tray 4 and the lower seedling-growing tray 5. A plurality of sleeve tubes 15 corresponding to the seedling-growing conical tubes 6 are embedded and installed on the partition plate 14. The sleeve tubes 15 can be sleeved on the bottom openings of the seedling-growing conical tubes 6, and together with the seedling-growing conical tubes 6 and the seed soaking grooves 10, they form a breeding cup structure. After being sleeved, the inner walls of the sleeve tubes 15 are flush with the inner walls of the seedling-growing conical tubes 6.

[0063] See Figure 4 、 Figure 9 and Figure 11, through the design of the partition 14 and the nested tube 15, the seedling cup structure can be divided into three sections, and the pocket soil net 7 filled with the culture medium can fill the seedling cup structure, so that when the seedlings are transplanted, the growth of their roots will make them intricately distributed in the mesh of the pocket soil net 7, that is, the soil ball itself will be formed, and it is only necessary to be able to take it out easily without being loose when transplanting;

[0064] Therefore, when transplanting, after opening the upper and lower seedling trays, the partition 14 and the nesting tube 15 are removed, part of the bottom soil ball can be exposed, and the soil ball and the seedlings can be taken out from above the seedling cone tube 6 by pushing the bottom of the soil ball upward;

[0065] Moreover, it is worth mentioning that the inverted cone-shaped design of the seedling raising cone tube 6 can further reduce the friction of the soil ball when it is separated from the seedling raising cone tube 6, thereby ensuring the integrity of the soil ball after it is taken out and further improving the survival rate of transplanted seedlings.

[0066] In one of the more preferred embodiments, the outer wall of the nested tube 15 located below the partition 14 is further provided with ventilation grooves, and the ventilation grooves are lower than the horizontal plane of the seeds.

[0067] By providing ventilation grooves on the outer wall of the nested tube 15, on the one hand, the culture matrix can be ventilated, and on the other hand, the moisture level can be controlled, which can not only moisten the seeds through the culture matrix, but also avoid excessive moisture for a long time to soak the seeds, so as to ensure the normal growth of the seedling root system.

[0068] In one of the more preferred embodiments, the upper seedling tray 4 is rotatably mounted with a buckle 18 at the edge position on both sides, and a torsion spring is installed at the connection between the buckle 18 and the upper seedling tray 4, and the side wall of the partition 14 is provided with a side groove for the buckle 18 to buckle into, see Figure 6 The partition 14 can be easily installed and removed through the claws 18 to facilitate the subsequent transplanting process.

[0069] In one of the more preferred embodiments, the inner diameter of the seed soaking groove 10 is larger than the outer diameter of the seedling cone tube 6, and the bottom of the soil net 7 is connected with a capillary core that can extend into the seed soaking groove 10. By connecting the capillary core to the bottom of the soil net 7, during the seed soaking process, the capillary core can be used to gradually guide the water in the seed soaking groove 10 to the culture medium in the soil net 7, so that the culture medium can remain moist. In this way, the damage to the seeds can be minimized during the subsequent seed puncture, thereby ensuring the normal sowing of the seeds and the subsequent normal growth.

[0070] The standard parts used in this embodiment can be directly purchased from the market. As for the non-standard structural components described in the specification and drawings, they can also be directly processed without any doubt based on the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0071] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
