Description

Technical Field

[0001] This invention belongs to the field of lemon seedling technology, specifically a layered, intensive, high-efficiency light-generating seedling device for lemon cultivation. Background Technology

[0002] Lemon seedling cultivation devices are specialized equipment used to provide a controllable and suitable artificial environment for lemon seeds during germination and early seedling growth. The core objective of these devices is to cultivate robust, disease-free, and high-quality lemon seedlings by precisely controlling conditions such as light, temperature, water, and fertilizer, laying a solid foundation for subsequent transplanting and field growth. Furthermore, through multi-layer design, they maximize the number of seedlings cultivated within a limited space and integrate functions such as water and fertilizer irrigation and environmental control to achieve batch and efficient management.

[0003] The prior art document, CN119032799A, discloses a tiered seedling rack for edible mushroom cultivation, relating to the field of seedling rack technology. It includes a rack and a frame, with two frames and placement rods fixedly connected to each frame. Multiple mushroom sticks are placed on the two placement rods. A collection frame is installed below the mushroom sticks to collect water dripping from their surface after spraying. Compared to the prior art where lower mushroom sticks are placed directly below upper ones, causing water from the upper sticks to fall onto the lower ones and leading to excessive water absorption and hindering growth, this method collects the dripping water, preventing excessive water absorption by the lower sticks and allowing for water recycling and reuse, thus utilizing water resources more effectively. Compared to the prior art where water droplets fall directly to the ground, causing dirt accumulation, this method reduces the occurrence of water droplets falling directly to the ground, contributing to environmental hygiene. Although the above-mentioned device achieves an intensive effect by collecting dripping water, it still follows the traditional seedling rack, fixing the positions of core components such as the middle layer board, light source, and nozzle. In addition, in order to provide sufficient light for lemon cultivation, LED tubes or reflectors are often used to enhance natural light and ensure the light intensity and quality required for seedling photosynthesis. However, even so, there are still considerable differences in the size of the seedling growth space and the ambient light intensity of each layer, which is not conducive to the uniformity of seedling growth. Summary of the Invention

[0004] To address the problem mentioned in the background art that the fixed setting of traditional seedling raising devices results in significant differences in the size of the seedling growth space and the ambient light intensity of each layer, which is detrimental to the uniformity of seedling growth, this invention provides a layered, intensive, and high-light-efficiency seedling raising device for lemon cultivation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a layered, intensive, high-efficiency seedling raising device for lemon cultivation, comprising a vertical support, wherein multiple fixed seedling boards are equidistantly fixed to the inner side of the vertical support from top to bottom, and horizontal supports are spaced apart from the multiple fixed seedling boards, with the sidewalls of the horizontal supports fixed to the vertical support; and further comprising: Interlayer expansion mechanism, wherein the interlayer expansion mechanism is located on a fixed seedling board; A self-rotating mechanism, which is connected to an interlayer expansion mechanism; The interlayer expansion mechanism extends the interlayers of multiple fixed seedling trays outwards, simultaneously driving a self-rotating mechanism to rotate the seedling pots. The interlayer expansion mechanism also includes a cylinder fixed to the top of the fixed seedling tray, with a top connecting rod fixed to the output end of the cylinder. Vertical rack rods are fixed to both sides of the top connecting rod. Several movable seedling trays slide through the outer walls of each vertical rack rod. Each movable seedling tray is half the size of a fixed seedling tray. A groove is formed in the middle of each movable seedling tray, and a horizontal rack is fixed to the inner side of each groove. Each vertical rack rod and... A horizontal rack meshes with thick gears, and multiple thick gears are rotatably connected to a horizontal support via a rotating shaft. The self-rotating mechanism includes an insert rod that slides through a pair of movable seedling trays, and the middle of each insert rod is fixed to the horizontal support. The insert rod provides good support, ensuring the stability of the movable seedling trays during movement. Each insert rod has a pair of double-sided racks fixed to its two side edges, and the outer walls of the double-sided racks are meshed with gear discs. When the double-sided racks mesh sequentially with the outer and inner gear discs, the seedling trays rotate clockwise with the gear discs. The rotation and reversal effectively improve the uniformity of light exposure, and allows seedlings to be positioned with different sides facing the stronger light source according to their growth stage, effectively increasing the survival rate. Several gear discs are evenly distributed on the movable seedling plate, and the center of each gear disc is rotatably connected to the movable seedling plate. Each adjacent pair of gear discs meshes with each other. The top of the movable seedling plate has several circular holes, the number of which matches the number of gear discs, and both have the same axis. Therefore, the seedling pot containing lemon seedlings needs to be placed on the gear discs through the circular holes, serving as a limiting mechanism. To prevent seedling trays from slipping during the movement of the movable seedling trays, when no one is passing by, the cylinder can be activated to move the top connecting rod upwards, simultaneously moving the vertical rack rods on both sides upwards within the protective sleeve rod. The teeth on the vertical rack rods mesh with the thick gears, and the rotation of the thick gears can drive the horizontal racks on both sides to move away from each other, thus moving a pair of movable seedling trays outwards. The sliding grooves prevent any obstruction to the movement of the vertical rack rods, which not only increases the growth space for seedlings in the middle layer but also increases the distance between adjacent fixed seedling trays, making full use of the space inside the seedling greenhouse.

[0006] Preferably, a protective sleeve is slidably sleeved on the outer wall of the vertical rack rod. The protective sleeve is configured as multiple segments. One end of each segment of the protective sleeve is fixedly connected to the fixed seedling board, and the other end abuts against the movable seedling board.

[0007] Preferably, the outer surfaces of the plurality of thick gears are provided with protective covers, the protective covers are all fixedly connected to the movable seedling board, and the side walls of the protective covers abut against the protective sleeve rod.

[0008] Preferably, the inner cavity of each of the multiple movable seedling boards is provided with a cavity, and the inserting rod, double-sided rack and gear disk are all located in the cavity.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a combination of structures including a movable seedling tray, vertical racks, horizontal racks, and a gear disk to fully utilize the space within the seedling greenhouse, avoiding dense seedling cultivation that could negatively impact seedling growth. The teeth on the vertical rack mesh with a thick gear; the rotation of the thick gear drives the horizontal racks on both sides to move away from each other, effectively extending the movable seedling trays of the adjustable interlayer outwards. This improves the living space for middle-layer seedlings and increases the spacing between adjacent fixed seedling trays. During this process, the seedling pots rotate via the gear disk, ensuring ample sunlight exposure. The movable seedling trays are unfolded when no one is passing by and retracted when someone is present, without obstructing staff movement and maximizing the use of the greenhouse space.

[0010] This invention facilitates the rotation of the seedling tray by setting up a double-sided rack and insert rod, thereby enabling the gear plate to receive light from all directions. When the movable seedling plate is unfolded or retracted, the gear plate meshes with the double-sided rack in sequence. Since the top of the movable seedling plate has several round holes, the number of which is the same as that of the gear plate, and the two have the same axis, the gear plate drives the seedling tray to rotate. When the double-sided rack meshes with the outer or inner gear disk, the rotation directions are different. Viewed from the outside in, the gear disk rotates first in the forward direction and then in the reverse direction, effectively improving the uniformity of light. Furthermore, depending on the growth status of the seedlings, different faces of the seedlings can be aligned with the side with stronger light, and this position can be kept to receive appropriate light for an appropriate duration, effectively increasing the survival rate of the seedlings. In addition, multiple through rods running through the inside of a pair of movable seedling trays can provide good support, making the movable seedling trays stable during movement.

[0013] 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.

[0014] like Figures 1 to 10 As shown, this invention provides a layered, intensive, high-efficiency seedling raising device for lemon cultivation, including a vertical support 1. Multiple fixed seedling boards 2 are equidistantly fixed to the inner side of the vertical support 1 from top to bottom. Horizontal supports 3 are spaced apart from the multiple fixed seedling boards 2, and the sidewalls of the horizontal supports 3 are fixed to the vertical support 1. The device also includes: Interlayer expansion mechanism 4 is located on fixed seedling board 2; The self-rotating mechanism 5 is connected to the interlayer expansion mechanism 4; The interlayer expansion mechanism 4 can expand the interlayers of multiple fixed seedling trays 2 outwards, and simultaneously drive the self-rotating mechanism 5 to rotate the seedling pots. The interlayer expansion mechanism 4 also includes a cylinder 409 fixed to the top of the fixed seedling tray 2. A top connecting rod 401 is fixed to the output end of the cylinder 409. Vertical rack rods 406 are fixed to both sides of the top connecting rod 401. Several movable seedling trays 404 slide through the outer wall of the vertical rack rods 406. The size of each movable seedling tray 404 is half that of the fixed seedling tray 2. A sliding groove 405 is opened in the middle of each movable seedling tray 404. A horizontal rack 407 is fixed to the inner side of each sliding groove 405. Each vertical rack rod 406 and the horizontal rack 407 mesh with a thick gear 408. Multiple thick gears 408 mesh with each other. All 08 are rotatably connected to the horizontal support 3 via a rotating shaft; the self-rotating mechanism 5 includes a sliding rod 503 that passes through a pair of movable seedling plates 404, and the middle of the multiple sliding rods 503 is fixed to the horizontal support 3; a pair of double-sided racks 504 are fixed to the two sides of each sliding rod 503, and the outer walls of the double-sided racks 504 are meshed with gear disks 501; several gear disks 501 are evenly distributed on the movable seedling plates 404, and the center of each gear disk 501 is rotatably connected to the movable seedling plate 404, and each pair of adjacent gear disks 501 mesh with each other; several round holes 502 are opened on the top of the movable seedling plate 404, the number of round holes 502 is the same as the number of gear disks 501, and the two have the same axis.

[0015] The above-described scheme describes a seedling raising device with a stable three-dimensional frame constructed from vertical support 1 and horizontal support 3. The fixed seedling board 2 serves as the basic support platform and is uniformly fixed within this frame, forming an initial, fixed-height, intensive seedling raising space. When it is necessary to provide better vertical light and ventilation for the growing lemon seedlings, the interlayer expansion mechanism 4 is activated. Upon receiving power from the interlayer expansion mechanism 4, the self-rotating mechanism 5 begins operation, driving the seedling pots on it to rotate slowly and uniformly, thereby improving the uniformity of seedling growth.

[0016] like Figures 2 to 5 , Figure 8 As shown, a protective sleeve 402 is slidably sleeved on the outer wall of the vertical rack rod 406. The protective sleeve 402 is configured with multiple segments. One end of each segment of the protective sleeve 402 is fixedly connected to the fixed seedling plate 2, and the other end abuts against the movable seedling plate 404. A protective cover 403 is provided on the outside of multiple thick gears 408. The protective cover 403 is fixedly connected to the movable seedling plate 404, and the side wall of the protective cover 403 abuts against the protective sleeve 402.

[0017] The above solution works as follows: When staff need to walk between the vertical supports 1, the vertical rack rod 406 is pressed down, causing the thick gear 408 and horizontal rack 407 to pull a pair of movable seedling trays 404 inwards, without occupying extra space. When no one is passing by, the cylinder 409 can be activated to move the top connecting rod 401 upwards, simultaneously moving the vertical rack rods 406 on both sides upwards within the protective sleeve rod 402. The teeth on the vertical rack rods 406 mesh with the thick gear 408, and the rotation of the thick gear 408 can drive the horizontal racks 407 on both sides to move away from each other, thus moving the pair of movable seedling trays 404 outwards. The sliding groove 405 prevents obstruction of movement of the vertical rack rods 406. This increases the growth space for seedlings in the middle layer and also increases the distance between adjacent fixed seedling trays 2, making full use of the space inside the seedling greenhouse.

[0018] like Figures 6 to 10 As shown, the inner cavity of each of the multiple movable seedling boards 404 is provided with a cavity 505, and the insert rod 503, double-sided rack 504 and gear disk 501 are all located in the cavity 505.

[0019] The above solution employs the following method: Since the top of the movable seedling plate 404 has several round holes 502, the number of which matches the number of gear discs 501, and both have the same axis, the seedling pots containing lemon seedlings must be placed on the gear discs 501 through the round holes 502 to act as a limit, preventing the seedling pots from slipping during the movement of the movable seedling plate 404. Whenever the movable seedling plate 404 moves outward, the insert rod 503 fixed to the horizontal support 3 slides relative to the movable seedling plate 404, while the gear discs 501 rotatably connected to the cavity 505 of the movable seedling plate 404 mesh with the double-sided rack 504 in sequence. Furthermore, each pair of adjacent gear discs 501 meshes with each other; therefore, as long as one gear disc 501 on each side of the insert rod 503 rotates, the remaining gear discs 501 will also rotate. This ensures that when the moving seedling plate 404 unfolds or retracts, the gear disk 501 drives the seedling pot to rotate, allowing it to receive light from all directions. When the double-sided rack 504 meshes with the outer and inner gear disks 501 in sequence, the seedling pot can rotate forward and backward with the gear disks 501, effectively improving the uniformity of light. Furthermore, depending on the growth status of the seedlings, different sides of the seedlings can be aligned with the side with stronger light, and this position can be maintained to receive appropriate light for an appropriate duration, effectively increasing the survival rate of the seedlings.

[0020] Working principle and usage process of this invention: First, when no one is passing by, the cylinder 409 can be activated to move the top connecting rod 401 upward, simultaneously moving the vertical rack rods 406 on both sides upward within the protective sleeve rod 402. The teeth on the vertical rack rods 406 mesh with the thick gear 408. The rotation of the thick gear 408 causes the horizontal racks 407 on both sides to move away from each other, thus moving a pair of movable seedling plates 404 outward. The sliding groove 405 prevents obstruction of movement to the vertical rack rods 406. This increases the growth space for seedlings in the middle layer and increases the distance between adjacent fixed seedling plates 2, making full use of the space in the seedling greenhouse and avoiding dense seedling cultivation that could affect their growth and health. When staff need to walk between the vertical supports 1, the same principle applies, but in reverse: the vertical rack rods 406 are pressed down, causing the thick gear 408 and horizontal racks 407 to move the pair of movable seedling plates 404 inward, retracting them without occupying extra space. Secondly, whenever the movable seedling plate 404 moves outward, the insert rod 503 fixed to the horizontal support 3 slides relative to the movable seedling plate 404, and the gear disk 501 rotatably connected to the cavity 505 of the movable seedling plate 404 meshes with the double-sided rack 504 in sequence. Furthermore, each pair of adjacent gear disks 501 meshes with each other, so as long as one gear disk 501 on each side of the insert rod 503 rotates, the remaining gear disks 501 will also rotate. Since the top of the movable seedling plate 404 has several round holes 502, the number of which matches the number of gear disks 501, and both have the same axis, the seedling pot containing lemon seedlings must be placed on the gear disk 501 through the round holes 502 to limit its movement and prevent it from slipping off during the movement of the movable seedling plate 404. This ensures that when the moving seedling plate 404 unfolds or retracts, the gear disk 501 drives the seedling pot to rotate, allowing it to receive light from all directions. Finally, when the double-sided rack 504 meshes with the outer gear disk 501, the outer gear disk 501 drives the remaining inner gear disks 501 to rotate in one direction. When the double-sided rack 504 moves to the inner side and meshes with the gear disk 501, the inner gear disk 501 changes its rotation direction, causing the seedling tray to rotate clockwise and counterclockwise with the gear disk 501. This effectively improves the uniformity of light exposure and allows the seedlings to be positioned with different sides facing the stronger light source, ensuring they receive appropriate light exposure for a longer period, thus increasing the seedling survival rate. Furthermore, multiple through rods 503 penetrating the interior of the pair of movable seedling trays 404 provide good support, ensuring the stability of the movable seedling trays 404 during movement.
