Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation technology, and in particular to a seedling cultivation device. Background Technology

[0002] Seedlings are tree seedlings with roots and trunks. All seedlings cultivated in a nursery, regardless of age, are called seedlings before they leave the nursery. Seedlings can be categorized as seedlings grown from seed, seedlings propagated by vegetative propagation, transplanted seedlings, and seedlings left in the nursery bed. Seedlings can also be classified as trees and shrubs. Generally, there are more tree seedlings in the north and more shrubs in the south. Seedlings require cultivation racks and other cultivation devices during the cultivation process.

[0003] Currently, Chinese utility model patent CN222776655U discloses a seedling cultivation rack. This application relates to the field of cultivation racks and discloses a seedling cultivation rack including a water storage tank. A base is fixedly connected to one side of the upper surface of the water storage tank, and a motor is fixedly connected to the center of the lower surface of the water storage tank. This application connects the motor to a stirring paddle, so that the motor drives the stirring paddle to rotate, causing the stirring paddle to fully mix the water and culture solution inside the water storage tank. Then, a hose connects the nozzle to the water storage tank, so that a water pump sprays the liquid inside the water storage tank from the nozzle through the hoses on both sides. Excess culture solution flows out from the water outlet at the bottom of the cultivation cylinder and flows into the base for storage. Then, excess culture solution flows into the water storage tank through the through hole, which is convenient for spraying seedlings again, reducing resource waste. This achieves the goal of facilitating the spraying of culture solution on seedlings and collecting and utilizing excess culture solution.

[0004] According to the aforementioned patent, existing seedling cultivation racks have significant defects in humidity control and filtration purification. Specifically, they lack a humidity monitoring structure, making it impossible to sense the substrate humidity inside the cultivation cylinder in real time. This results in the watering process relying entirely on manual operation, making it difficult to achieve automated adjustment. Furthermore, the watering method is singular, and the amount of water added cannot be controlled, easily leading to seedling dehydration or waterlogging. In terms of filtration purification, the filter screen inside the cultivation cylinder is fixed, making it difficult to disassemble and clean. At the same time, the through-hole between the base and the water storage tank is not equipped with a filtration device, allowing impurities such as fallen leaves and substrate particles to directly enter the water storage tank during waste liquid return. This not only easily causes nozzle clogging but also contaminates the cultivation solution. Therefore, a seedling cultivation device is proposed to solve the above problems. Utility Model Content

[0028] This utility model provides a cultivation device for seedling planting, aiming to solve the significant defects of existing seedling planting cultivation racks in terms of humidity control and filtration purification. Specifically, these defects include: the lack of a humidity monitoring structure, making it impossible to sense the humidity of the substrate inside the cultivation cylinder in real time, resulting in the watering process relying entirely on manual operation, making it difficult to achieve automated adjustment; the watering method is also singular, and the amount of water added cannot be controlled, easily causing seedlings to suffer from water shortage or water accumulation; in terms of filtration purification, the filter screen inside the cultivation cylinder adopts a fixed design, making it difficult to disassemble and clean; at the same time, no filtration device is installed in the through hole between the base and the water storage tank, allowing impurities such as fallen leaves and substrate particles to directly enter the water storage tank during the waste liquid return process, which not only easily causes nozzle blockage but also contaminates the cultivation solution.

[0029] like Figure 1-6 As shown in the figure, the seedling cultivation device provided in this embodiment of the present invention includes a water tank 1, a stirring structure 2 is provided inside the water tank 1, a cylindrical cover 3 is connected to the top of the water tank 1, and a cultivation mechanism 4 is provided inside the cylindrical cover 3.

[0030] The cultivation mechanism 4 includes a filter structure 41 installed inside the water tank 1. A support rod 42 is bolted to the top of the filter structure 41. A seedling placement structure 43 is installed at the bottom of the outer side of the support rod 42. A light lamp 44 is bolted to the top of the outer side of the support rod 42. A top plate 45 is welded to the top of the support rod 42. A four-way pipe 46 is installed at the top of the top plate 45. The top of the front side of the four-way pipe 46 penetrates the top of the top plate 45. A flow control valve 47 is connected to the bottom of the front side of the four-way pipe 46. A nozzle 48 is connected to the bottom of the flow control valve 47. A water pump 49 is bolted to the rear side of the water tank 1. The absorption end of the water pump 49 is connected to the rear side of the water tank 1. The output end of the water pump 49 is connected to the bottom of the four-way pipe 46. An external controller is connected to the water pump 49, the flow control valve 47, and the light lamp 44.

[0031] In this invention, a water tank 1, a stirring structure 2, a cylindrical cover 3, and a cultivation mechanism 4 are configured. The stirring structure 2 inside the water tank 1 operates continuously to thoroughly mix the water and nutrient solution, preventing solute precipitation and uneven concentration. An external controller starts the water pump 49 according to a preset program, drawing the mixture from the water tank 1 through the absorption end and delivering it to the four-way pipe 46 at the top of the top plate 45 through the output end. The flow rate is then precisely adjusted by the flow control valve 47 at the bottom front of the four-way pipe 46, and finally evenly atomized and sprayed onto the seedling structure 43 through the nozzle 48. The seedling structure 43 is equipped with a humidity monitoring structure to monitor the substrate humidity of the planted seedlings in real time. When the humidity is lower than the threshold, the controller automatically replenishes water by linking the water pump 49 and the flow control valve 47 to ensure that the seedling roots are in a suitable humidity environment. Part of the sprayed water or nutrient solution is absorbed by the seedling roots, and the excess liquid flows into the filter structure 41 at the bottom of the seedling structure 43 for multi-layer filtration and interception. Impurities such as fallen leaves and substrate particles are removed, and the purified liquid is returned to water tank 1, forming a closed-loop circulation system to achieve waste liquid recycling and reuse. At the same time, the light lamp 44 on the top of the outer side of the support rod 42 is set to turn on and off and light intensity by an external controller to provide suitable photoperiod for the seedlings and promote photosynthesis. The cylinder cover 3 prevents the sprayed liquid from splashing out and keeps the device clean. The external controller controls the water pump 49, flow regulating valve 47 and light lamp 44 through preset programs. For example, it can automatically adjust the spraying frequency and light duration according to the growth stage of the seedlings. During the seedling stage, low flow intermittent spraying (such as spraying 50ml every 2 hours) is set, with 12 hours of light. During the mature stage, the spray volume is increased and the light is extended to 16 hours to achieve precise cultivation. The support rod 42, as the core support structure, integrates modules such as seedling placement, lighting, spraying and filtration into the cylinder cover 3, which saves space and ensures that all components work together to meet the needs of large-scale seedling cultivation for automation and efficiency.

[0032] Please refer to the following: Figure 5 The stirring structure 2 includes a motor 21 bolted to the bottom of the water tank 1. An external controller is connected to the motor 21. The output end of the motor 21 passes through the bottom of the water tank 1, and a shaft 22 is fixedly connected to the output end of the motor 21. A stirring rod 23 is bolted to the outside of the shaft 22 and is located inside the water tank 1. In this embodiment, by setting the stirring structure 2, the motor 21 drives the shaft 22 and the stirring rod 23 to rotate, performing three-dimensional stirring of the water and nutrient solution in the water tank 1. This quickly eliminates concentration stratification, ensures uniform mixing, and avoids localized over-concentration that could burn the roots. The external controller can preset the stirring frequency to maintain the stability of the nutrient solution.

[0033] For further information, please continue to refer to [link / reference]. Figure 4The filter structure 41 includes a support ring plate 411 welded to the bottom inside the cylinder shroud 3. An activated carbon filter screen 412 is mounted on top of the support ring plate 411, and a stainless steel screen 413 is mounted on top of the activated carbon filter screen 412. The stainless steel screen 413 is snapped into the inside of the cylinder shroud 3, and its top is bolted to the bottom of the support rod 42. In this embodiment, by setting the filter structure 41, excess liquid flows out from the bottom of the seedling structure 43 and first passes through the stainless steel screen 413 to intercept large particles such as fallen leaves and insect carcasses. It then flows into the activated carbon filter screen 412, where the porous structure of the activated carbon adsorbs organic matter and odors from the nutrient solution. Simultaneously, microfiltration further removes colloidal particles. Finally, the liquid is guided through the support ring plate 411 to the through-hole of the water tank 1, completing the purification and return process, and effectively preventing clogging of the nozzle 48 and contamination of the storage area.

[0034] Please continue to refer to this. Figure 5 The seedling structure 43 includes a disc 431 fixedly connected to the outside of the support rod 42. The top of the disc 431 has grooves 432 around its perimeter. The front and rear sides of the grooves 432 have positioning grooves 433. A culture tube 434 is installed inside the groove 432. Positioning blocks 435 are welded to the front and rear sides of the culture tube 434. The positioning blocks 435 are snapped into the inside of the positioning grooves 433. A support net 436 is welded to the bottom inside the culture tube 434. A humidity sensor 437 is installed on the outside of the culture tube 434. The sensing end of the humidity sensor 437 is located inside the culture tube 434. The humidity sensor 437 is connected to an external controller. In this embodiment, by setting up the seedling placement structure 43, the groove 432 at the top of the disc 431 provides a standardized installation position for the cultivation cylinder 434. The cultivation cylinder can be quickly loaded and unloaded through the snap-fit ​​structure between the positioning block 435 and the positioning groove 433 of the groove, which facilitates seedling transplantation or substrate replacement. The support mesh 436 inside the cultivation cylinder 434 adopts a metal mesh design with a 1mm aperture, which can not only bear the substrate and prevent the root system from penetrating and causing substrate loss, but also guide excess water to seep evenly into the filter structure 41, avoiding clogging of the stainless steel screen 413. During this process, the humidity sensor 437 monitors the substrate humidity inside the cultivation cylinder 434 in real time. The sensing end penetrates 5cm into the substrate to accurately obtain the root layer humidity data (accuracy ±2%RH). When the humidity is lower than the preset threshold, the controller triggers the water pump 49 and the flow regulating valve 47 to replenish water. When it is higher than the threshold, the spraying stops. Combined with the timed supplemental lighting of the light lamp 44, a closed-loop operation of monitoring, adjustment and feedback is formed to achieve dynamic and precise control of the seedling growth environment.

[0035] Please refer to Figure 1Each of the triangular sections at the bottom of the water tank 1 is welded with a support leg 5, and the bottom of the support leg 5 is equipped with an anti-slip pad. In this embodiment, by setting the support legs 5, the triangular support legs 5 combined with the anti-slip pad improve the stability of the device, prevent the water pump 49 from vibrating and shifting, and reduce the risk of tipping over. When fully loaded, it can withstand a lateral thrust of 50N, making it suitable for mechanized handling.

[0036] Additionally, please refer to Figure 1 The top right side of the water tank 1 is connected to a water supply pipe 6, which can be connected to an external water supply pipe or a feed pipe. In this embodiment, by setting up the water supply pipe 6, which adopts a quick-connect interface design, it can be quickly connected to an external water supply pipe (such as a greenhouse drip irrigation system) or a feed pipe (such as a nutrient solution concentrate tank). When water or fertilizer needs to be added, it can be added directly into the water tank 1 through the water supply pipe 6.

[0037] Additionally, please refer to Figure 6 A drain pipe 7 is connected to the left side of the bottom of the water tank 1, and a solenoid valve 8 is connected to the front of the drain pipe 7. The solenoid valve 8 is connected to an external controller. In this embodiment, by setting the drain pipe 7 and the solenoid valve 8, the external controller can be programmed to open the solenoid valve 8 at regular intervals to drain the impurities deposited at the bottom of the water tank 1 to prevent the growth of microorganisms, or the water inside the water tank 1 can be directly drained, the water tank 1 can be cleaned, and then refilled to facilitate use.
