Description

Technical Field

[0001] This invention relates to the field of agricultural seedling technology, specifically to a seedling raising device for agricultural cultivation. Background Technology

[0002] In agricultural production, seedling raising is a crucial step in crop cultivation. Many crop seeds require soaking before sowing to promote germination, increase germination rate and speed, and remove pathogens and impurities from the seed surface. However, traditional seedling raising methods have many shortcomings. For example, different steps such as soaking seeds, planting seedlings, and transplanting seedlings require workers to complete them step by step, making the operation process relatively complex. Therefore, existing seedling raising devices have improved upon these shortcomings.

[0003] For example, the breeding device and method for lettuce vegetables disclosed in Chinese Patent Publication No. CN119278793B can realize the unified management of the soaking, planting and seedling picking processes through the seed soaking structure, soil storage structure, rotating structure and seedling cultivation structure. It can realize the automatic placement of seeds and soil covering after seed soaking. The seedling cultivation structure can save operation time, reduce the space occupied by the equipment, and can be reused.

[0004] However, due to its complex structure and limited space, during long-term use, various components of the device may become loose, deformed, or damaged due to frequent operation, soil corrosion, moisture, and other factors, affecting the normal use and service life of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a seedling raising device for agricultural cultivation, so as to solve at least one technical problem existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seedling raising device for agricultural cultivation, comprising a seedling tray, wherein the seedling tray is composed of an upper seedling tray and a lower seedling tray that can be assembled and combined vertically.

[0007] The bottom of the upper seedling tray is integrally formed with multiple seedling cones, the top of the seedling cones is open, and a soil-holding net for holding the culture medium at the bottom is installed inside the seedling cones.

[0008] The top of the lower seedling tray is provided with multiple soaking troughs corresponding to the seedling cone tube. When the upper seedling tray and the lower seedling tray are installed together, the bottom of the soaking trough and the inner wall of the seedling cone tube together form a seedling cup structure for seedling cultivation.

[0009] It also includes a puncture section located in the lower seedling tray, which is used to push the seeds in the soaking trough upwards and break through the mesh of the soil-collecting net until they penetrate into the culture medium in the seedling cone tube.

[0010] Optionally, the system also includes a mounting frame, which comprises a base plate and side frames fixed on both sides thereon. A detachable top plate frame is installed on the top of each of the side frames on both sides. The upper seedling tray and the lower seedling tray are slidably installed between the side frames on both sides. A second screw is rotatably installed on the top of the lower seedling tray. The top end of the second screw passes through the upper seedling tray and the top plate frame and is threadedly connected to the through end of the upper seedling tray. A first screw is rotatably installed between the top plate frame and the base plate. The first screw passes through the upper seedling tray and the lower seedling tray and is threadedly connected to the through end of the lower seedling tray. A knob is fixed on the top end of both the first screw and the second screw.

[0011] Optionally, the puncture part includes a puncture tube fixed to the top of the base plate and a core rod slidably installed in the puncture tube. A through hole is opened at the bottom of the center of the seed soaking tank for the puncture tube to pass through. An elongated groove is opened on the outer wall of the puncture tube located in the through hole. A friction pin is fixed on the outer wall of the core rod and extends out of the elongated groove. The friction pin is slidably connected to the inner wall of the through hole.

[0012] Optionally, the top opening of the puncture tube is flared, and the top end of the core rod is concave.

[0013] Optionally, the bottom end of the seedling cone tube is provided with a wavy protrusion, and the through groove formed between the wavy protrusions can connect the interior of the formed breeding cup structure with the soaking tank. Adjacent soaking tanks are connected by a connecting water channel opened in the lower seedling tray. The outer walls on both sides of the lower seedling tray are connected to water injection pipes that are connected to the water channels at the edge, and the water injection pipes are connected to the external water supply pipes.

[0014] Optionally, it also includes a partition between the upper seedling tray and the lower seedling tray. The partition is fitted with a plurality of nested tubes corresponding to the seedling cone tubes. The nested tubes can be fitted onto the bottom opening of the seedling cone tubes and together with the seedling cone tubes and the seed soaking troughs, they form a seedling cup structure. After fitting, the inner wall of the nested tubes is flush with the inner wall of the seedling cone tubes.

[0015] Optionally, the outer wall of the nested tube located below the partition is also provided with ventilation slots, and the ventilation slots are lower than the horizontal level of the seeds.

[0016] Optionally, the upper seedling tray is rotatably mounted with claws on both sides of the upper seedling tray, and a torsion spring is installed at the connection between the claws and the upper seedling tray. The side wall of the partition is provided with a side groove for the claws to engage.

[0017] Optionally, the seedling cone tube is designed in an inverted cone shape.

[0018] Optionally, the inner diameter of the soaking trough is larger than the outer diameter of the seedling cone tube, and the bottom of the soil-collecting net is connected to a capillary core that can extend into the soaking trough.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] I. This invention, through its upper and lower combined seedling tray design, achieves unified management of the seed soaking, planting, and seedling removal processes, simplifies the operation process, realizes a multi-functional integrated seedling solution, improves seedling efficiency, and has a simple structure with a small footprint. During long-term use, it can be easily reused and cleaned after use, which can greatly reduce problems such as loosening, deformation, and damage caused by frequent operation, and improve the normal service life of the device. Moreover, the innovative design of the puncture part enables seeds to be planted into the culture medium accurately and quickly, reducing the manual operation time and errors in traditional sowing methods.

[0021] Second, this invention uses a puncture-seeding method to precisely control the planting depth and position of seeds, ensuring that seeds are planted at the optimal depth, which improves the germination rate of seeds and the growth quality of seedlings. Moreover, by injecting water at the bottom, it reduces the evaporation of water from the soil surface, maintains a moist soil environment, and is conducive to the development of seedling roots.

[0022] Third, the modular design of the device makes assembly, disassembly and cleaning more convenient, which facilitates management and maintenance during the seedling process. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 11 The present invention provides a technical solution: a seedling raising device for agricultural cultivation, including a seedling tray, which is composed of two upper seedling trays 4 and lower seedling trays 5 that can be assembled and combined vertically.

[0037] The bottom of the upper seedling tray 4 is integrally formed with multiple seedling cone tubes 6. The top of the seedling cone tube 6 is open, and a soil-holding net 7 for holding the bottom of the culture medium is installed inside the seedling cone tube 6.

[0038] The top of the lower seedling tray 5 is provided with multiple soaking troughs 10 corresponding to the seedling cone tube 6. When the upper seedling tray 4 and the lower seedling tray 5 are installed together, the bottom of the soaking trough 10 and the inner wall of the seedling cone tube 6 together form a seedling cup structure for seedling cultivation.

[0039] It also includes a piercing part located in the lower seedling tray 5, and the piercing part is used to push the seeds in the soaking trough 10 upward and break through the mesh of the soil-collecting net 7 until they penetrate into the culture medium in the seedling cone tube 6.

[0040] When using this seedling raising device, first separate the upper seedling tray 4 and the lower seedling tray 5, then place the soil-holding net 7 into the seedling cone tube 6 to seal its bottom opening. The soil-holding net 7 can be fixed to the seedling cone tube 6 by simple adhesion to prevent it from shifting. Then fill the seedling cone tube 6 with the culture medium (such as soil or nutrient soil) and hold it in place with the soil-holding net 7 to form a simple culture cup structure. The soil-holding net 7 can be made of existing fiber mesh, which can prevent the culture medium from falling off, and also has good flexibility and appropriate pore size to allow plant roots to penetrate and grow, and also provides conditions for subsequent seed penetration.

[0041] Meanwhile, the soaking tank 10 is filled with soaking solution, such as water or other special soaking solution. Seeds are then placed in their respective soaking tanks 10 for soaking. During the soaking process, the water absorption and soaking progress of the seeds are observed regularly to ensure they fully absorb water and swell. Once the predetermined soaking time has elapsed, the prepared upper seedling tray 4 and lower seedling tray 5 are directly assembled, so that the bottom end of the seedling cone tube 6 enters the soaking tank 10 and contacts its inner wall. This creates a seedling cup structure for seedling cultivation, formed by the bottom of the soaking tank 10 and the inner wall of the seedling cone tube 6. Figure 8 As shown, at the same time, the piercing part pushes the seeds in the soaking tank 10 upward and breaks through the mesh of the soil-collecting net 7 until it penetrates into the culture medium in the seedling cone tube 6, thereby completing the seed planting process. The combined upper seedling tray 4 and lower seedling tray 5 can be placed on the shelf without taking up too much space.

[0042] When the seedlings have emerged and need to be transplanted, the upper and lower seedling trays can be separated again to remove the culture medium and seedlings wrapped in the soil net 7 together, ensuring the integrity of the seedling roots and soil ball, thus ensuring the survival rate of the seedlings after transplanting.

[0043] In this way, by combining the upper seedling tray 4 and the lower seedling tray 5, not only can the unified management of the soaking, planting and seedling removal processes be realized, and the seed piercing and planting can be carried out automatically after the seeds are soaked, but the structure is also simple and occupies little space. During long-term use, it can be easily reused and cleaned after use, which can greatly reduce the problems of loosening, deformation and damage caused by frequent operation, 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, compared to the traditional method of placing the seeds first and then covering them with soil or substrate, not only allows for precise control of the seed planting depth, fixing the seeds directly in a specific position in the soil and ensuring that the seeds are planted at the optimal depth, since the suitable planting depth varies for different crop seeds, precise sowing helps to improve the germination rate and seedling growth quality, but also ensures that the distribution of seeds in the seed tray or soil is more accurate and uniform.

[0045] In one preferred embodiment, an installation structure and implementation method are provided for adjusting the combination or disassembly of the upper seedling tray 4 and the lower seedling tray 5;

[0046] It also includes a mounting frame, which includes a base plate 1 and side frames 2 fixed on both sides. A detachable top plate frame 3 is installed on the top of each side frame 2. The upper seedling tray 4 and the lower seedling tray 5 are slidably installed between the side frames 2. A second screw 9 is rotatably installed on the top of the lower seedling tray 5. The top of the second screw 9 passes through the upper seedling tray 4 and the top plate frame 3 and is threadedly connected to the through-hole of the upper seedling tray 4. A first screw 8 is rotatably installed between the top plate frame 3 and the base plate 1. The first screw 8 passes through the upper seedling tray 4 and the lower seedling tray 5 and is threadedly connected to the through-hole of the lower seedling tray 5. A knob is fixed on the top of both the first screw 8 and the second screw 9.

[0047] For details, please refer to [link / reference]. Figure 1-3 By sliding the upper seedling tray 4 and the lower seedling tray 5 between the side frames 2 on both sides of the base plate 1, they can be vertically slidably limited so that the corresponding seedling cone tube 6 and the seed soaking trough 10 can correspond when they are installed or disassembled. Secondly, when it is necessary to combine or disassemble the two seedling trays, the distance between the upper seedling tray 4 and the lower seedling tray 5 can be adjusted by turning the second screw 9 with the knob, thereby achieving the purpose of combination or disassembly.

[0048] After the two are combined and installed, by rotating the first screw 8, the upper seedling tray 4 and the lower seedling tray 5 can be moved closer to or away from the bottom plate 1 together, so as to provide conditions for subsequent seed piercing. Furthermore, the way the second screw 9 passes through the top plate frame 3 allows it to slide vertically within the through hole without causing any interference to its travel.

[0049] In addition, the detachable design of the top plate frame 3 makes it easy to disassemble, replace and clean the two seedling trays, which facilitates post-transplanting handling.

[0050] In one preferred embodiment, an implementation of the puncture site is provided;

[0051] The puncture section includes a puncture tube 11 fixed to the top of the base plate 1 and a core rod 12 slidably installed inside the puncture tube 11. A through hole is provided at the bottom of the center of the seed soaking tank 10 for the puncture tube 11 to pass through. A long groove is provided on the outer wall of the puncture tube 11 located in the through hole. A friction pin 13 is fixed on the outer wall of the core rod 12, extending out of the long groove, and the friction pin 13 is slidably connected to the inner wall of the through hole.

[0052] For details, please refer to [link / reference]. Figure 4-5 The top of the piercing tube 11 and the core rod 12 together form a groove for seeds to be placed in. The top of the piercing tube 11 is initially lower than or flush with the bottom of the soaking tank 10. This ensures that the seeds are soaked in water. At the same time, the seeds are located inside the piercing tube 11, which also prevents the seeds from directly contacting the piercing tube 11 when it pierces the soil net 7, thus avoiding damage to the seeds.

[0053] During planting, as described above, rotating the first screw 8 causes the two assembled seedling trays to move together closer to the base plate 1. At this time, the piercing tube 11, fixed to the base plate 1, moves upwards due to relative motion and pierces the culture medium through the mesh of the soil-holding net 7. During this process, the upward movement of the piercing tube 11 is controlled by the locking action of the friction pin 13 via the long groove, ensuring that the piercing tube 11 and the core rod 12 remain in place. Figure 4 The grooves in the center allow the seeds to be pierced and transported through them;

[0054] After being transported to the designated position, the two seedling trays are moved away from the base plate 1 by rotating the first screw 8 in the reverse direction. At this time, due to the friction between the friction pin 13 and the through hole, the piercing tube 11 will move downwards before the core rod 12. The core rod 12 then supports the seeds, preventing them from returning along the same path. Since the seeds expand after being soaked in water, their diameter will be larger than the diameter of the top of the core rod 12. Figure 10 The seeds are shown before and after being soaked in water;

[0055] After the puncture tube 11 moves down first, the culture medium will fall and fill the position of the puncture tube 11 to provide some support and limit the seed. When the long groove on the puncture tube 11 contacts the friction pin 13 again, the puncture tube 11 will drive the core rod 12 to move down and reset. Then the culture medium will fill the position of the core rod 12, thus completing the seed puncture and planting process.

[0056] In this way, by removing the piercing tube 11 and the core rod 12 in sequence, the seeds can be prevented from falling down with them, further ensuring the sowing accuracy of the seeds and improving the subsequent seedling cultivation effect.

[0057] In one preferred embodiment, the top opening of the puncture tube 11 is flared, and the top end of the core rod 12 has a concave surface, see [reference]. Figure 10The flared design of the puncture tube 11 and the concave design of the core rod 12 are designed to better position the seeds and allow them to expand after absorbing water.

[0058] In one preferred embodiment, the bottom end of the seedling cone tube 6 is provided with a wavy protrusion, and the through groove formed between the wavy protrusions allows the interior of the formed seed cup structure to communicate with the seed soaking tank 10. Adjacent seed soaking tanks 10 are connected by a connecting water channel 16 opened in the lower seedling tray 5. The outer walls on both sides of the lower seedling tray 5 are connected to water injection pipes 17 that communicate with the connecting water channel 16 at the edge position, and the water injection pipes 17 are connected to the external water supply pipe.

[0059] As can be seen from the above, the seed soaking tank 10 is mainly used for soaking seeds. In order to facilitate the subsequent watering process, the water channel 16 and the water injection pipe 17 are designed to facilitate watering and soaking the seeds. After planting, since the seed soaking tank 10 forms the bottom of the seedling cup structure, water is injected into the seed soaking tank 10 during the planting stage. The water can contact the culture medium through the groove between the wavy protrusions, and then achieve the effect of watering from below under the action of capillary action. In this way, the irrigation process can be integrated, further simplifying the seedling process and improving work efficiency.

[0060] In this way, the seed soaking trough 10 can play different roles at different stages, further simplifying the structure. It can also reduce water evaporation, guide the roots to grow downwards, and improve the root coverage of the seedlings. At the same time, by precisely controlling the water injection speed and volume, each seedling cup structure can obtain the required water evenly, avoiding possible local over-wetting or over-drying situations, ensuring the consistency of the seedling growth environment, and facilitating the cultivation of uniform and strong seedlings.

[0061] In one preferred embodiment, an implementation method is provided to facilitate the removal of the soil ball and seedling from the seedling cone 6 during subsequent transplanting;

[0062] It also includes a partition 14 located between the upper seedling tray 4 and the lower seedling tray 5. Multiple nested tubes 15 corresponding to the seedling cone tube 6 are embedded in the partition 14. The nested tubes 15 can be fitted onto the bottom opening of the seedling cone tube 6 and together with the seedling cone tube 6 and the seed soaking trough 10, they form a seedling cup structure. After being fitted, the inner wall of the nested tube 15 is flush with the inner wall of the seedling cone tube 6.

[0063] See Figure 4 , Figure 9 and Figure 11Through the design of partition 14 and nested tube 15, the seedling cup structure can be divided into three sections, and the soil-holding net 7 filled with culture medium can fill the seedling cup structure. When the seedling is transplanted, the root system will be intricately distributed in the mesh of the soil-holding net 7 due to its growth, that is, the soil ball itself will be formed. It is only necessary to make it easy to remove without loosening during transplanting.

[0064] Therefore, during transplanting, after opening the upper and lower seedling trays and removing the partition 14 and nesting tube 15, part of the bottom soil ball can be exposed. By pushing the bottom of the soil ball upward, the soil ball and seedling can be taken out from the top of the seedling cone tube 6.

[0065] Moreover, it is worth mentioning that the seedling cone 6 is designed with an inverted cone shape, which can further reduce the friction when the soil ball is separated from the seedling cone 6, thereby ensuring the integrity of the soil ball after removal and further improving the survival rate of seedling transplantation.

[0066] In one preferred embodiment, the outer wall of the nested tube 15 located below the partition 14 is also provided with a ventilation groove, and the ventilation groove is lower than the horizontal plane of the seed.

[0067] By opening ventilation slots on the outer wall of the nested tube 15, the culture medium can be ventilated, and the moisture level can be controlled. This allows the seeds to be moistened through the culture medium while avoiding excessive water soaking of the seeds for a long time, thus ensuring the normal growth of the seedling roots.

[0068] In one preferred embodiment, latches 18 are rotatably mounted on both sides of the upper seedling tray 4, and torsion springs are installed at the connection between the latches 18 and the upper seedling tray 4. The side wall of the partition 14 has side grooves for the latches 18 to engage. (See also...) Figure 6 The clips 18 facilitate the installation and removal of the partition 14, which is convenient for subsequent transplanting processes.

[0069] In one preferred embodiment, the inner diameter of the soaking trough 10 is larger than the outer diameter of the seedling cone tube 6, and the bottom of the soil-holding net 7 is connected to a capillary core that can extend into the soaking trough 10. By connecting the capillary core to the bottom of the soil-holding net 7, during the soaking process, the capillary core can guide the water in the soaking trough 10 to the culture medium in the soil-holding net 7 so that the culture medium can be kept moist. This can minimize the damage to the seeds during subsequent seed piercing, so as to ensure normal sowing and subsequent normal growth of the seeds.

[0070] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0071] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
