Description

Technical Field

[0001] This invention relates to the field of fruit seedling cultivation technology, and in particular to an intelligent fruit seedling cultivation box and cultivation method. Background Technology

[0002] In the process of modern fruit and vegetable cultivation, especially the industrialized and intensive production of high-value-added seedlings, it is crucial to provide seedlings with a stable and precisely controllable growth environment. Seedlings have different requirements for environmental factors such as light, temperature, and humidity, as well as cultivation space, at different growth stages. Traditional ground planting or fixed multi-layer trellis cultivation models have problems such as low space utilization, imprecise environmental control, and high labor management costs, making it difficult to meet the needs of efficient and standardized production.

[0003] Currently, the spacing between the cultivation components for fruit seedlings is the same, which makes it impossible to make personalized and differentiated adjustments according to the different space requirements (such as crown size and light competition) of different types of fruit seedlings or different growth stages of the same fruit seedling. This limits the flexibility and applicability of the system. When a layer of fruit seedlings needs more growth space, it is impossible to effectively adjust the spacing between two adjacent cultivation components in the vertical direction. This results in the fruit seedlings not being able to obtain the optimal growth space at different growth stages, which leads to problems such as excessive vegetative growth, uneven light, and poor ventilation.

[0004] Therefore, the industry urgently needs an integrated and highly automated seedling cultivation device to achieve highly safe adjustment of cultivation units to adapt to the spatial requirements of different growth stages, thereby creating optimal conditions for seedling growth and improving cultivation efficiency and the quality of finished seedlings. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent seedling cultivation box and cultivation method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intelligent seedling cultivation box includes a box body. A guide plate fixed to the inner wall of the bottom of the box body is movably connected to the outer wall of a multi-set cultivation component. Elastic inserts are installed on the sides of the cultivation components. A vertical plate is fixed to the inner wall of the bottom of the box body. The surface of the vertical plate has insertion holes for use with the elastic inserts. A lifting mechanism is installed on the inner wall of the bottom of the box body. A lifting plate is installed at the output end of the lifting mechanism. An electric telescopic rod is fixed to one side of the outer wall of the lifting plate. An installation plate is fixed to the output end of the electric telescopic rod. A fertilizer application mechanism is installed on the side of the installation plate. A hook is fixed to the bottom of the installation plate. An installation block is fixed to the back of the elastic insert. The surface of the installation block has locking holes for use with the hooks.

[0008] As a further embodiment of the present invention: a door is hinged to one side of the box body, an observation window is installed on the surface of the door, and a controller is installed on the side of the door.

[0009] As a further embodiment of the present invention: the cultivation component includes a connecting plate movably connected to the outer wall of the guide plate and a placement box fixed between the two connecting plates. The placement box contains multiple sets of cultivation units, each cultivation unit including a cultivation basin and a filter screen welded to its bottom. A collection tray is installed on the side of the placement box by a pull-out method.

[0010] As a further embodiment of the present invention: the lifting mechanism includes a mounting plate and a support rod, the support rod is fixed to the inner wall of the bottom of the box, the mounting plate is fixed to the outer wall of the top of the support rod, and the lifting plate and the support rod are movably connected.

[0011] As a further embodiment of the present invention: a threaded rod is movably connected between the bottom outer wall of the mounting plate and the bottom inner wall of the housing, and a drive motor for driving the threaded rod is fixed on the top of the mounting plate.

[0012] As a further embodiment of the present invention: the fertilizer application mechanism includes a nozzle connected between a hose and a mounting plate, and a three-way pipe fixed to the top of the mounting plate.

[0013] As a further embodiment of the present invention: a mounting shaft is fixed to the top of the mounting plate, and a swing arm is movably connected to the outer circumference of the mounting shaft. The swing arm and the nozzle are fixedly connected by an intermediate rod. Multiple swing arms are movably connected by a linkage rod through a rotating shaft. A torsion spring is sleeved on the outer circumference of one of the mounting shafts, and the two ends of the torsion spring are respectively fixed to the outer circumference of the mounting shaft and the top outer wall of the swing arm.

[0014] As a further aspect of the present invention: daylight lamps are installed on both inner walls of the box.

[0015] As a further aspect of the present invention: an environmental regulation mechanism is installed on the inner wall of one side of the box.

[0016] A method for intelligent cultivation of fruit seedlings includes the following steps:

[0017] S1: Place the seedling cultivation pot in the spring, and the spring will push the conical rod to automatically lock into the hole of the upright plate and lock the height.

[0018] S2: When height adjustment is required, the controller starts the drive motor, which drives the threaded rod to move the lifting plate to the target height; then the electric telescopic rod pushes the hook to engage with the locking hole of the mounting block, retracts and pulls out the tapered rod to release the lock;

[0019] S3: After the lifting mechanism adjustment components are adjusted to the new height, the electric telescopic rod releases the tension, and the spring pushes the tapered plug into the new insertion hole to re-fix it;

[0020] S4: During the cultivation period, sunlight lamps provide illumination; the environmental control mechanism automatically controls the temperature and humidity inside the chamber;

[0021] S5: During fertilization, the external fertilizer supply system delivers fertilizer to the installation plate through the three-way pipe. The nozzle sprays out fertilizer, and the reaction force causes the swing arm to swing around the installation axis. Through the linkage rod, all nozzles swing synchronously to achieve uniform fertilization.

[0022] Compared with the prior art, the present invention provides an intelligent seedling cultivation box and cultivation method, which has the following beneficial effects:

[0023] 1. The cultivation components are fixed by elastic engagement between the tapered rod and multiple sets of holes on the upright plate. Combined with the automatic unlocking and moving mechanism driven by the lifting mechanism and electric telescopic rod, the vertical spacing between the cultivation components of each layer can be flexibly and automatically adjusted according to the height requirements of the seedlings at different growth stages, maximizing the use of the three-dimensional space inside the box and avoiding the plant growth being restricted due to insufficient space.

[0024] 2. The cultivation pots are placed together in the placement box, and there is a pull-out collection tray at the bottom, which can not only stabilize the substrate and seedlings, but also facilitate the collection of excess water or waste liquid, keep the cultivation environment clean, and simplify maintenance operations.

[0025] 3. Through a precision lifting mechanism consisting of a drive motor, a threaded rod, and a lifting plate, and the lateral drive of the hook by the electric telescopic rod, the automatic addressing, grasping, and movement of the target cultivation component is realized. The matching design of the hook and the locking hole ensures the reliability of the unlocking and locking action of the locking mechanism. The entire adjustment process does not require manual intervention and has a high degree of automation.

[0026] 4. The fertilization mechanism adopts a multi-arm design linked by torsion springs and linkage rods, which enables the nozzle to automatically swing laterally during fertilization, significantly increasing the spray coverage area of ​​the fertilizer solution. This ensures that the seedlings in multiple cultivation pots in the same placement box can receive uniform nutrients, improving fertilization efficiency and effectiveness.

[0027] 5. Key functional modules such as sunlight lamps, environmental control mechanisms, lifting mechanisms, and fertilization mechanisms are integrated inside the enclosure and centrally managed through a unified controller. The observation window facilitates intuitive monitoring, enabling coordinated, precise, and intelligent control of various growth factors such as light, temperature, humidity, space, and nutrients, creating a stable and programmable optimal growth environment for the seedlings.

[0028] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention has a simple structure and is easy to operate. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Example 1:

[0040] A type of intelligent seedling cultivation box, such as Figures 1 to 8As shown, the device includes a housing 1, with a door 3 hinged to one side. An observation window 2 is installed on the surface of the door 3, and a controller 4 is installed on the side of the door 3. A guide plate 13 is fixed to the inner wall of the bottom of the housing 1 by screws. Multiple cultivation components are slidably connected to the outer wall of the guide plate 13. Each cultivation component includes a connecting plate 17 slidably connected to the outer wall of the guide plate 13 and a placement box 5 fixed between two connecting plates 17. Multiple cultivation units are placed inside the placement box 5. Each cultivation unit includes a cultivation basin 20 and a filter screen 19 welded to its bottom. A collection tray 32 is installed on the side of the placement box 5 by a pull-out mechanism. A tapered rod 33 is slidably connected to the side of the connecting plate 17. A spring 22 is sleeved on the outer wall of the tapered rod 33. The outer wall, and the two ends of the spring 22 are respectively fixed to the outer wall of the connecting plate 17 and the inner wall of the tapered plug 33. The bottom inner wall of the box 1 is fixed with a vertical plate 14 by screws. The surface of the vertical plate 14 is provided with a plurality of plug holes 15 that cooperate with the tapered plug 33. The bottom inner wall of the box 1 is equipped with a lifting mechanism. The output end of the lifting mechanism is equipped with a lifting plate 11. The outer wall of the lifting plate 11 is fixed with screws to an electric telescopic rod 16. The output end of the electric telescopic rod 16 is fixed with a mounting plate 29. The side of the mounting plate 29 is equipped with a fertilizer applicator. The bottom of the mounting plate 29 is fixed with a hook 28 by screws. One end of the tapered plug 33 is fixed with a mounting block 18 by screws. The surface of the mounting block 18 is provided with a locking hole 21 that cooperates with the hook 28.

[0041] When cultivating fruit seedlings, the substrate is first filled into the cultivation pot 20 and the seedlings are cultivated using the substrate. Then, the cultivation pot 20 is placed in the placement box 5. The collection tray 32 is inserted horizontally into the placement box 5 through the insertion hole on the side of the placement box 5 to collect the excess water or waste liquid that seeps out. In the initial state, the elasticity of the spring 22 is used to make the conical insertion rod 33 snap into the inner wall of one of the sets of insertion holes 15 on the side of the upright plate 14 to limit the height of the placement box 5. By setting multiple sets of insertion holes 15, the distance between two adjacent cultivation components can be adjusted to ensure that as the seedlings continue to grow, the distance between the two cultivation components can be adjusted to ensure that the seedlings have enough production space.

[0042] When it is necessary to adjust the spacing between two adjacent cultivation components, the height of the hook 28 is adjusted using the lifting mechanism. After the hook 28 moves above one of the cultivation components, the hook 28 is driven to move laterally using the electric telescopic rod 16. After the hook 28 moves to the front of the locking hole 21, the hook 28 is driven to move down using the lifting mechanism. After the hook 28 moves to a position directly opposite the locking hole 21, the hook 28 is driven to return using the electric telescopic rod 16, causing the hook 28 to engage with the inner wall of the locking hole 21. As the electric telescopic rod 16 continues to drive the hook 28 to return, the spring 22 is gradually stretched, causing the conical insert 33 to gradually disengage from the inner wall of the insertion hole 15. After the conical insert 33 is completely disengaged from the insertion hole 15, the cultivation unit is driven to move up or down using the lifting mechanism to dynamically adjust the height of the cultivation component.

[0043] When it is necessary to fertilize the seedlings in the cultivation module, the lifting mechanism and electric telescopic rod 16 can be used to adjust the position of the fertilization mechanism in the longitudinal and transverse directions, so that the fertilization mechanism can fertilize the seedlings in different cultivation modules.

[0044] The observation window 2 is installed on the surface of the box door 3, providing operators with a transparent window to directly monitor the growth status of the seedlings, substrate moisture, and facility operation without opening the box.

[0045] The lifting mechanism includes a mounting plate 6 and a support rod 10. The support rod 10 is fixed to the bottom inner wall of the housing 1 by screws. The mounting plate 6 is fixed to the top outer wall of the support rod 10 by screws. The lifting plate 11 and the support rod 10 are slidably connected. A threaded rod 23 is rotatably connected between the bottom outer wall of the mounting plate 6 and the bottom inner wall of the housing 1. A drive motor 8 is fixed to the top outer wall of the mounting plate 6 by screws. The output end of the drive motor 8 is fixedly connected to the top of the threaded rod 23. The threaded rod 23 and the lifting plate 11 are threadedly connected.

[0046] The drive motor 8 can drive the threaded rod 23 to rotate. During the rotation of the threaded rod 23, the lifting plate 11 moves up or down under the guidance of the mounting block 18, thereby adjusting the height of the hook 28 and the fertilizer application mechanism.

[0047] The fertilization mechanism includes a swing arm 24 and a nozzle 26. The nozzle 26 and the mounting plate 29 are connected by a flexible hose. The swing arm 24 and the nozzle 26 are fixedly connected by an intermediate rod 27. The top of the mounting plate 29 is fixed with a mounting shaft 31. The swing arm 24 and the mounting shaft 31 are rotatably connected. Multiple swing arms 24 are rotatably connected by a linkage rod 25 through a rotating shaft. A torsion spring 30 is sleeved on the outer circumference of one of the mounting shafts 31. The two ends of the torsion spring 30 are respectively fixed to the outer circumference of the mounting shaft 31 and the top outer wall of the swing arm 24. A three-way pipe 12 is installed on the top of the mounting plate 29.

[0048] When fertilization of the seedlings is required, the three-way pipe 12 is connected to the fertilizer delivery mechanism through the pipeline. The fertilizer delivery mechanism is used to input fertilizer into the installation plate 29. The fertilizer is then diverted by the nozzle 26 so that the final fertilizer is sprayed out into the cultivation unit to fertilize the seedlings. During the fertilization process, the fertilizer has a certain pressure, which causes the torsion spring 30 to undergo elastic deformation under the pressure. The swing arm 24 swings relative to the installation shaft 31, and the nozzle 26 swings left and right in the lateral direction to increase the fertilization range. The linkage of the linkage rod 25 makes the movements of multiple nozzles 26 consistent, thereby improving the uniformity of fertilization of the seedlings.

[0049] Both inner walls of the box 1 are equipped with daylight lamps 9;

[0050] Users can centrally set and control key parameters such as the illumination duration and intensity of the daylight lamp 9, the lifting height and speed of the lifting mechanism, the extension and retraction stroke of the electric telescopic rod 16, and the start / stop and fertilizer application amount of the fertilization mechanism through the interface of the controller 4, so as to realize the automated and precise management of the seedling cultivation environment.

[0051] An environmental control mechanism 7 is installed on one inner wall of the box 1;

[0052] The environmental control mechanism 7 integrates sensors and actuators to automatically monitor and regulate key environmental parameters such as temperature, humidity and gas composition inside the chamber 1. When the monitored values ​​deviate from the preset ideal range for seedling growth, the mechanism drives the corresponding heating, humidification, ventilation or gas replenishment devices to work, thereby dynamically maintaining a stable and suitable intelligent cultivation environment.

[0053] Working principle: First, the operator places the cultivation pots 20 one by one into the placement box 5. The collection tray 32 at the bottom of each placement box 5 is used to receive the exudate. In the initial state, the tapered insertion rod 33 on the side of the connecting plate 17 automatically engages with the corresponding height insertion hole 15 on the upright plate 14 under the elastic force of the spring 22, locking the entire cultivation assembly at the initial height position.

[0054] When the growth of the seedlings requires adjustment of the vertical spacing between adjacent cultivation components, the controller 4 instructs the drive motor 8 to rotate the threaded rod 23, driving the lifting plate 11 to move longitudinally along the support rod 10 to the height of the target cultivation component; the electric telescopic rod 16 pushes the mounting plate 29 and its bottom hook 28 to extend laterally so that they are aligned and locked into the locking hole 21 on the mounting block 18 at the end of the tapered insert 33; then the electric telescopic rod 16 retracts, pulling the mounting block 18 through the hook 28, stretching the spring 22 so that the tapered insert 33 is completely removed from the current insertion hole 15, and the cultivation component is unlocked; the lifting mechanism can then drive the entire component to rise or fall. After reaching the new target height, the electric telescopic rod 16 releases the tension, and the spring 22 rebounds to push the tapered insert 33 into another insertion hole 15 on the upright plate 14 corresponding to the new height, completing the height adjustment and re-fixing;

[0055] Throughout the entire cultivation cycle, the daylight lamps 9 on both sides of the chamber provide simulated lighting according to a preset program, and the environmental regulation mechanism 7 continuously monitors and automatically regulates environmental parameters such as temperature and humidity inside the chamber.

[0056] When fertilization is needed, the external fertilizer supply system connects to the T-pipe 12 via a hose to deliver fertilizer to the mounting plate 29. Under pressure, the fertilizer is sprayed out from the nozzle 26. Its reaction force causes the swing arm 24 to overcome the torsion of the torsion spring 30 and swing around the mounting shaft 31. Through the linkage rod 25, it drives all nozzles to swing left and right synchronously, expanding the spray coverage of the fertilizer solution and achieving uniform fertilization.

[0057] Example 2:

[0058] A method for intelligent cultivation of fruit seedlings includes the following steps:

[0059] S1: Place the seedling cultivation pot 20 into the pot, and the spring 22 pushes the conical insert 33 to automatically snap into the hole 15 of the upright plate 14 to lock the height.

[0060] S2: When the height needs to be adjusted, the controller 4 starts the drive motor 8, which drives the threaded rod 23 to move the lifting plate 11 to the target height; then the electric telescopic rod 16 pushes the hook 28 into the locking hole 21 of the mounting block 18, retracts and pulls out the tapered insert 33, and releases the lock;

[0061] S3: After the lifting mechanism adjustment assembly is moved to the new height, the electric telescopic rod 16 releases the tension, and the spring 22 pushes the tapered plug 33 into the new plug hole 15 to re-fix it;

[0062] S4: During the cultivation period, the daylight lamp 9 provides light; the environmental regulation mechanism 7 automatically controls the temperature and humidity inside the box;

[0063] S5: When fertilizing, the external fertilizer supply system delivers fertilizer to the installation plate 29 through the three-way pipe 12. The nozzle 26 sprays out fertilizer, and the reaction force causes the swing arm 24 to swing around the installation shaft 31. Through the linkage rod 25, all nozzles 26 swing synchronously to achieve uniform fertilization.
