Description

Technical Field

[0001] This utility model belongs to the field of seedling tray technology, and specifically relates to a seedling tray for green-skinned long eggplant. Background Technology

[0002] Seedling raising of green-skinned long eggplant is a crucial preliminary step in the planting process. Specifically, it refers to the process of artificially controlling environmental conditions and optimizing cultivation management before the green-skinned long eggplant is officially transplanted to the field, so as to promote the germination of green-skinned long eggplant seeds into seedlings and their growth into robust seedlings. Its core purpose is to provide high-quality seedlings with consistent growth status and strong stress resistance for subsequent field planting, thereby ensuring the overall yield and quality of green-skinned long eggplant. In the seedling raising operation of green-skinned long eggplant, the seedling tray is the core tool for carrying the seedling substrate and seeds. Its performance and structural design directly affect the seedling raising efficiency, space utilization rate and seedling growth quality. Therefore, selecting a suitable and efficient seedling tray is crucial for the smooth progress of the green-skinned long eggplant seedling raising process. To meet the needs of vegetable seedling cultivation, various specialized seedling trays have been developed in related technical fields, including one with the publication number "CN220068366U". A Chinese patent discloses a vegetable seedling tray, which mainly includes a seedling tray body. A seedling trough is formed on the upper surface of the seedling tray body, and three mounting holes are formed at the bottom of the seedling trough. A water-soaked cotton rope is fitted into the mounting holes. A water trough is formed on the lower surface of the seedling tray body, and the bottom end of the water-soaked cotton rope is embedded in the water trough. A water inlet is installed on the side of the seedling tray body. This existing vegetable seedling tray shows certain advantages in application. By designing water-soaked cotton ropes in the mounting holes and water troughs at the bottom of the seedling tray body, water can be filled into the water trough during use. Seedling soil and seeds are placed in the seedling trough. When water needs to be added to the seedling trough, the water-soaked cotton ropes are wetted and can evenly inject water into the seedling soil in the seedling trough. This not only simplifies the watering operation and makes watering more convenient, but also ensures uniform moisture distribution in the seedling soil, facilitating seedling use and effectively improving seedling results. It has been applied in various vegetable seedling scenarios, including green eggplant. However, in the actual seedling cultivation of green eggplant, especially in large-scale and intensive seedling cultivation scenarios, the existing vegetable seedling trays have gradually revealed obvious defects and shortcomings. Specifically, their overall structure is relatively simple, and no special structure has been designed for the stacking of seedling trays. This makes it inconvenient to stack them quickly during use. If multiple seedling trays are to be spliced ​​and stacked together, an additional support structure is required; otherwise, flexible stacking cannot be achieved. This inability to stack quickly results in the seedling trays occupying a large amount of space during use. Green eggplant seedling cultivation typically requires greenhouses, The low space utilization rate of seedling trays in greenhouses and other limited spaces not only increases the cost of seedling sites but also limits the number of seedlings produced at one time, making it difficult to meet the demand for efficient space utilization in large-scale green eggplant seedling production. It also brings inconvenience to the handling and management operations during the seedling process. It is evident that the existing vegetable seedling trays have obvious shortcomings in adapting to the space utilization requirements of large-scale green eggplant seedling production and need to be improved. Therefore, targeted design improvements are needed to solve the problems of not being able to stack quickly and occupying a lot of space, thereby improving their practicality and applicability in the green eggplant seedling production scenario.

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a green-skinned long eggplant seedling tray to solve the problems raised in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A seedling tray for green eggplant includes several frames. The seedling tray body is placed inside the frame. Limiting mechanisms are fixedly installed at the four corners of the top of the frame.

[0007] As a preferred technical solution, the top outer side of the card block is provided with an installation guide slope, and the side of the card block is set in a right trapezoidal shape.

[0008] As a preferred technical solution, the spray water replenishment mechanism includes a main water pipe, which is fixedly installed in the middle of the bottom of the frame.

Secondly, during the application of this technical solution, by setting up a spray water replenishment mechanism and a detachable seedling tray body, it is possible to easily connect to an external water supply system during use, so as to realize automated and uniform water replenishment of the seedling substrate without the need for manual watering of each seedling. Moreover, the seedling tray body and the frame can be separated, which facilitates subsequent seedling inspection and transplanting. This achieves the effects of reducing manual operation, reducing labor intensity, ensuring stable water supply, improving seedling effect, and enhancing the flexibility of seedling management. It solves the problems of existing technologies where seedling tray water replenishment depends on manual labor, uneven water distribution, and insufficient convenience of seedling management.

[0014] Example refer to Figures 1 to 5 This embodiment of a green eggplant seedling tray includes several frames 1. The seedling tray body 2 is placed inside the frame 1. Limiting mechanisms 3 are fixedly installed at the four corners of the top of the frame 1. Insertion shafts 4 are fixedly installed at the four corners of the bottom of the frame 1. The ends of the insertion shafts 4 are inserted into the inside of the bottom limiting mechanisms 3. Each frame 1 is assembled by interlocking with the limit mechanisms 3 through the insertion shafts 4. A spray water replenishment mechanism 5 is fixedly installed at the bottom of the frame 1. The limiting mechanism 3 includes a sleeve frame 31 and an insert block 32. The sleeve frame 31 is fixedly installed at the top four corners of the frame 1, and the insert block 32 is fixedly installed at the bottom of the insertion shaft 4. The insert block 32 is inserted into the inside of the sleeve frame 31. A limiting module 33 is fixedly installed on the inner side of the sleeve frame 31. The end of the limiting module 33 passes through the sleeve frame 31 and the insert block 32 and engages. During the application of this device, when cultivating green eggplant seedlings, the seedling tray body 2 is first placed inside the frame 1. Then, the frames 1 are stacked and assembled according to the needs of the seedling scale. Another frame 1 is taken, and the insertion shaft 4 at the bottom four corners of the frame 1 is aligned with the limiting mechanism 3 at the top four corners of the lower frame 1. The upper frame 1 is pushed so that the end of the insertion shaft 4 is inserted into the inner side of the bottom limiting mechanism 3. At this time, the insert block 32 in the limiting mechanism 3 is inserted into the inside of the sleeve frame 31 along with the insertion shaft 4. When the insert block 32 is fully inserted into the sleeve frame 31, the sleeve frame... The limiting module 33 inside 31 is activated, and its end passes through the sleeve 31 and engages with the insert block 32 to fix the two frames 1. Multiple frames 1 can be stacked in this way without the need for additional structures to complete the assembly, which greatly saves seedling space and solves the problem of large space occupation of seedling trays in the existing technology. At the same time, the snap-fit ​​assembly does not require complicated operations and improves assembly efficiency. During the seedling process, the frame 1 provides stable support for the seedling tray body 2 and prevents the seedling tray body 2 from shifting and affecting the growth of seedlings. When it is necessary to replenish water for the green eggplant seedlings, the spray water replenishment mechanism 5 at the bottom of the frame 1 is activated, which can directly replenish water to the seedling substrate in the seedling tray body 2 without the need for manual watering, reducing labor intensity. The snap-fit ​​design of the limiting mechanism 3 also makes it easy to disassemble the frame 1 according to the seedling needs and flexibly adjust the number of stacks, further improving the convenience and adaptability of the device.

[0015] refer to Figures 1-3 and Figure 5The limiting module 33 includes a side frame 331 and a slot 332. The side frame 331 is fixedly installed on one side of the sleeve frame 31 that are close to each other. A limiting spring 333 is fixedly connected inside the side frame 331. A movable block 334 is fixedly installed on the inner end of the limiting spring 333. The movable block 334 is slidably connected to the inside of the side frame 331. A locking block 335 is fixedly installed on the inner side of the movable block 334. The slot 332 is opened on one side of the insertion blocks 32 that are close to each other. The end of the locking block 335 is inserted into the slot. Inside 332, a connecting shaft 336 is fixedly installed on the outer side of the movable block 334. The outer end of the connecting shaft 336 passes through the side frame 331 and is fixedly installed with a disassembly and reassembly pull-out shaft 337. The top outer side of the locking block 335 is provided with an installation guide slope 338. The side of the locking block 335 is set in a right-angled trapezoidal shape. During the application of this device, when the frame 1 is stacked and assembled, when the insertion block 32 at the bottom of the insertion shaft 4 is inserted into the sleeve frame 31, the insertion block 32 will first contact the installation guide slope 338 on the top outer side of the locking block 335. The inclined plane 338, due to the right-angled trapezoidal shape of the side of the locking block 335, guides the insertion block 32 to smoothly press against the locking block 335, causing the locking block 335 to move into the side frame 331. The locking block 335 drives the movable block 334 to slide synchronously inside the side frame 331. The movable block 334 presses against the limiting spring 333 inside the side frame 331, at which time the limiting spring 333 is in a compressed state. As the insertion block 32 continues to be inserted, when the slot 332 on the insertion block 32 engages with the locking block... When the 335 positions are aligned, the limit spring 333 is no longer compressed and returns to its original position, pushing the movable block 334 to move inward. The movable block 334 drives the locking block 335 to move synchronously, so that the end of the locking block 335 is precisely inserted into the inner side of the slot 332, completing the locking and fixing of the insert block 32 and the sleeve frame 31, thereby achieving stable assembly of the two frames 1. The whole process does not require additional manual fixing. The limit module 33 can be automatically locked by the force of the insert block 32, which greatly improves the assembly efficiency of the frame 1. When frame 1 needs to be disassembled, the operator pulls the disassembly and assembly pull-out shaft 337. The disassembly and assembly pull-out shaft 337 drives the movable block 334 to move outward through the connecting shaft 336. The movable block 334 compresses the limit spring 333 and drives the locking block 335 to disengage from the locking slot 332, releasing the limit on the insertion block 32. At this time, the upper frame 1 can be easily lifted upward, so that the insertion block 32 can be pulled out from the sleeve frame 31. The disassembly process is simple and convenient, without the need for professional tools, reducing the difficulty of the operator's work. At the same time, the coordinated action of each component of the limit module 33 can ensure that frame 1 remains stable during stacking and use, avoiding the loosening of frame 1 due to vibration or external force, ensuring the stability of the seedling tray body 2 during the seedling process, and further improving the overall reliability of the device.

[0016] refer to Figures 1-4The sprinkler water supply mechanism 5 includes a main water pipe 51, which is fixedly installed at the bottom center of the frame 1. Horizontal water pipes 52 are fixedly connected to the bottom of the main water pipe 51 in a linear arrangement at equal intervals. Water supply nozzles 53 are fixedly connected to the bottom of the horizontal water pipes 52 in a linear arrangement at equal intervals. An external water pipe 54 is fixedly installed on one side of the main water pipe 51, and an external water supply pipe threaded connector 55 is fixedly connected to the outer end of the external water pipe 54. A protective side frame 6 is fixedly connected to the outer side of the seedling tray body 2. The protective side frame 6 and the outer corner of the frame 1 are both rounded. During the application of this device, when it is necessary to replenish water for the seedlings in the seedling tray 2 during the seedling cultivation of green eggplant, the external water supply pipe is first connected to the main water pipe 51 through the external water supply pipe threaded joint 55 at the outer end of the external water pipe 54. The water delivered by the external water supply system enters the main water pipe 51 through the external water pipe 54. The main water pipe 51 evenly distributes the water to the horizontally arranged water pipes at equal intervals at the bottom. Pipe 52, the horizontal water pipe 52 further distributes water to the water supply nozzles 53 arranged linearly at equal intervals at the bottom. The water supply nozzles 53 spray water evenly in a mist or column form into the seedling tray body 2 within the lower frame 1, providing a stable water supply for the seedling substrate and seedlings. The entire water supply process eliminates the need for manual watering of each seedling tray, reducing the labor intensity of operators. At the same time, the equally spaced horizontal water pipes 52 and water supply nozzles 53 ensure that water covers all seedling areas, avoiding localized water shortages or water accumulation, and guaranteeing seedling growth. In a stable environment, during the use of the seedling tray body 2, the outer protective side frame 6 fits tightly against the inner side of the sleeve frame 31, which can limit the displacement of the seedling tray body 2 within the frame 1 and prevent the seedling tray body 2 from tilting or the seedling substrate from spilling due to device movement or vibration. The outer corners of the protective side frame 6 and the frame 1 are all set to be rounded, which can prevent operators from being bumped by sharp corners when assembling, disassembling the frame 1 or during daily management, reduce operational safety hazards, and further improve the safety and reliability of the device during use.

[0017] Operating principle and advantages: When using this device, the first step is to stack and assemble the frames 1. Take the first frame 1 and place the seedling tray body 2 inside the frame 1. By setting the protective side frame 6 on the outside of the seedling tray body 2, the protective side frame 6 can fit tightly against the inside of the sleeve frame 31 at the four corners of the top of the frame 1 during use. The protective side frame 6 can limit the seedling tray body 2 and prevent it from sliding inside the frame 1. At the same time, by setting the protective side frame 6 and the outer corners of the frame 1 to be rounded, the operator can be prevented from being hit by the sharp corners during the assembly process, improving the safety of operation. Then take the second... Two frames 1 are assembled. The insertion shafts 4 at the four corners of the bottom of the first frame 1 are aligned with the sleeve 31 at the top of the first frame 1 and pressed down. By setting the insertion blocks 32 at the bottom of the insertion shafts 4, the insertion blocks 32 can gradually be inserted into the sleeve 31 during the pressing process. When inserted, the insertion blocks 32 press the mounting guide slope 338 on the outer side of the top of the locking block 335. By setting the mounting guide slope 338, the locking block 335 can move smoothly into the side frame 331. The movable block 334 slides synchronously with the locking block 335 and compresses the limiting spring 333 inside the side frame 331. When the insertion blocks 32 are fully inserted into the sleeve 31, by setting... The limiting spring 333 automatically resets and pushes the movable block 334 and the locking block 335 inward, thereby allowing the end of the locking block 335 to accurately insert into the slot 332 on the side of the insert block 32, completing the locking and fixing of the two frames 1. More frames 1 can be stacked in this manner, achieving rapid assembly of multiple seedling trays without the need for additional structures. Through the synergistic action of the components of the limiting mechanism 3, the problem of seedling trays not being able to be stacked quickly and requiring additional structures in existing technologies is solved, laying the foundation for efficient seedling cultivation. After the frames 1 are stacked and assembled, the pre-seedling preparation stage begins, with each frame... The seedling tray body 2 is filled with seedling substrate, and then the green eggplant seeds are sown in the seedling substrate. During this process, the frame 1 provides a stable support for the seedling tray body 2, ensuring that the seedling tray body 2 will not shift or tip over due to external forces during the subsequent seedling process, thus creating a stable environment for the germination of green eggplant seeds and the growth of seedlings. At the same time, the detachable design of the seedling tray body 2 and the frame 1 allows for operation space to be reserved for seedling inspection and transplanting in subsequent seedling management, thereby improving the flexibility of overall seedling management and making it convenient for operators to carry out various tasks according to the seedling progress. When regular watering is required during seedling cultivation, the spray watering mechanism 5 of this device is activated. The external water supply pipe threaded joint 55, connected to the external water pipe 54, allows for easy connection to the main water pipe 51. Water from the external water supply pipe enters the main water pipe 51, which then distributes the water evenly to the horizontally spaced water pipes 52 at the bottom. These horizontal water pipes further distribute the water to the water-replenishing nozzles 53 at the bottom. This allows water to be evenly sprayed into the seedling substrate of the seedling tray body 2 within the lower frame 1, precisely providing water for the growth of green eggplant seedlings. The coordinated operation of the main water pipe 51, the horizontal water pipe 52, and the water supply nozzle 53 achieves uniform water distribution and automated replenishment, eliminating the need for manual watering of each seedling tray. This reduces manual operation and labor intensity, avoids uneven water distribution caused by manual watering, ensures stable water supply for the growth of green eggplant seedlings, further improves seedling cultivation results, and ensures healthy seedling growth. When it is necessary to adjust the stacking quantity or remove the seedling tray body 2, the subsequent disassembly and adjustment operation is performed. The operator pulls the disassembly and assembly pull shaft 337. Through the connection between the disassembly and assembly pull shaft 337 and the connecting shaft 336, the connecting shaft 336 can drive the movable block 334 to move outward when pulled. The movable block 334 compresses the limit spring 333 and drives the locking block 335 to disengage from the locking groove 332. Through the cooperation structure between the locking block 335 and the locking groove 332, the locking block 335 can quickly release the limit on the insertion block 32 after disengagement. At this time, lifting the upper frame 1 allows the insertion shaft 4 and the insertion block 32 to be pulled out from the sleeve frame 31, completing the disassembly of the frame 1. After disassembly, they can be removed separately. The seedling tray body 2 is removed for inspection or transplanting of green eggplant seedlings. At the same time, the flexible stacking and disassembly design of the frame 1 allows for adjustment of the number of stacked frames 1 according to the scale of seedling cultivation. The number of stacked layers can be reduced for small-scale seedling cultivation and increased for large-scale seedling cultivation, thus adapting to different seedling needs. This flexible disassembly and adjustment method allows more seedling trays to be placed in the same space, greatly improving space utilization, reducing the use cost of seedling sites such as greenhouses, and increasing the number of seedlings cultivated at one time to meet the needs of large-scale green eggplant seedling cultivation. By optimizing the overall structural design, the shortcomings of existing technologies, such as large space occupation and insufficient adaptability of seedling trays, are made up for. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
