Description

Technical Field

[0001] This utility model relates to the field of seedling equipment technology, specifically a tea seedling cultivation and growth control device. Background Technology

[0002] Tea seedling cultivation is a crucial step in tea production, and its growing environment has a vital impact on the survival rate and robustness of the seedlings. Traditional tea seedling cultivation is mostly carried out in open-air nurseries or simple greenhouses, which are greatly affected by changes in the natural environment (such as temperature, humidity, and light), making precise control difficult and resulting in problems such as uneven seedling growth, unstable survival rates, and long seedling cultivation cycles.

[0003] While existing plant cultivation boxes can control the environment to some extent, they often have the following shortcomings: 1. The lighting system is fixed, making it impossible to flexibly adjust the angle and intensity of light according to the needs of tea seedlings at different growth stages or in different locations; 2. Seedling roots are easily damaged during transplanting. Therefore, there is an urgent need for a specialized device for tea seedling cultivation that can precisely control environmental factors and is easy to operate and transplant. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tea seedling cultivation and growth control device that is structurally reasonable, precisely controlled, easy to manage, and can effectively improve the survival rate and quality of tea seedlings.

[0005] To solve the above problems, the technical solution of this utility model is as follows: a tea seedling cultivation and growth control device, including a box body, a box door installed at the front end of the box body, a glass window provided on the box door, an exhaust pipe provided at the top of the box body, and at least one layer of cultivation racks provided inside, with a light-emitting component provided above each layer of cultivation racks. The cultivation rack includes a fixed plate, with positioning columns fixed to both ends of the fixed plate and installed on the inner wall of the box. A water inlet pipe is fixed to the upper part of one end, and a water outlet pipe is provided at the lower part of the other end. A cultivation plate is placed above the fixed plate. Several positioning holes are opened on the cultivation plate. Seedling pots are placed in the positioning holes. A movable seat for lifting the substrate is installed through the bottom surface of the seedling pot. A partition is installed at the bottom of the box, and two air outlet boxes are installed on the top of the partition. A ventilation component is provided below the partition. Several air outlet holes are provided on the top surface of the air outlet boxes, and the output end of the ventilation component is connected to the air outlet boxes.

[0006] Furthermore, a temperature and humidity sensor is installed at the top of the chamber, and a control panel is installed on the upper outer side; a humidifier is installed on one side of the chamber, and the output end of the humidifier is connected to an air duct that runs through the side of the chamber.

[0007] Furthermore, the lighting assembly includes a crossbar, a sleeve is slidably connected to the outer side of the crossbar, a mounting plate is fixed to the bottom of the sleeve, a set bolt is threaded onto the front end, a protective cover is connected to both ends of the mounting plate through gooseneck tubes, a full-spectrum LED light is installed inside the protective cover, and a dimming controller for adjusting the light intensity is installed at the front end of the protective cover.

[0008] Furthermore, both the inlet and outlet pipes are equipped with solenoid valves, and the end of the outlet pipe passes through the side wall of the tank and is connected to a drain pipe. A water storage tank is installed on the upper part of one side of the tank, and a water supply pipe is connected to the bottom of the water storage tank. The end of the inlet pipe passes through the side wall of the tank and is connected to the water supply pipe.

[0009] Furthermore, the front end of the fixed plate is provided with a liquid level observation window, and a liquid level sensor is installed inside. The two ends of the incubation plate are provided with handles, and a positioning ring that is fixed to the bottom and engaged with the inside of the fixed plate is fixedly connected.

[0010] Furthermore, the seedling pot is a frustum-shaped cone, wider at the top and narrower at the bottom, with a limiting ring fixed to its outer side and several water outlet holes on its bottom surface.

[0011] Furthermore, the movable seat includes a vertical rod that runs through the bottom of the seedling pot. A top plate and a bottom plate are fixedly connected to both ends of the vertical rod, and several water-permeable holes are opened on the top plate. A limiting cylinder sleeved on the outside of the vertical rod is fixedly connected to the bottom surface of the seedling pot.

[0012] Furthermore, the ventilation assembly includes a blower, the output end of which is connected to a heating tube, the output end of which is connected to two air outlet boxes, the heating tube being a round tube with multiple heating wires installed inside, and an inspection port with a protective net installed on the side of the housing.

[0013] The advantages of this invention compared to existing technologies are as follows: 1. The lighting components adopt a sliding sleeve and flexible gooseneck tube design, which can easily adjust the position and illumination angle of the LED lights to achieve differentiated supplemental lighting for tea seedlings in different locations. The dimming controller can precisely control the light intensity.

[0014] 2. The bottom immersion irrigation method (water supply through a fixed tray) is adopted, and water permeates evenly through the bottom holes of the seedling pot, avoiding rinsing the seedling leaves. Automatic water supply and drainage can be achieved through a liquid level sensor and a solenoid valve, ensuring precise control.

[0015] 3. The unique seedling pot and movable seat design allows the entire substrate ball to be easily pushed out by simply pushing the movable seat from the bottom upwards during transplanting, greatly reducing damage to the root system during the seedling removal process and improving the transplant survival rate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7As shown, a tea seedling cultivation and growth control device includes a well-sealed box 1. The front door of the box 1 is equipped with a glass window for easy observation of the interior. An exhaust pipe 2 is located on the top of the box 1 for air exchange. Multiple cultivation racks 3 are installed inside the box 1; this embodiment uses two racks. A temperature and humidity sensor 11 at the top of the box 1 is a key component for environmental sensing, used to monitor environmental parameters inside the box in real time. A control panel 12 is installed on the outside of the box 1.

[0026] A ventilation assembly 10 is installed at the bottom of the enclosure 1. Its operation is as follows: a blower 10.1 draws in air from outside the enclosure. The air flows through a heating pipe 10.2 (which contains multiple mesh-distributed heating wires to ensure uniform heating) for temperature regulation. The treated air is then delivered to two air outlet boxes 9 mounted on the partition 8. The top surface of each air outlet box 9 has numerous finely spaced air outlets, allowing warm air to diffuse evenly and gently from bottom to top throughout the entire enclosure, effectively avoiding the uneven temperature and humidity and dead air zones caused by traditional single-point air supply. Excess air and waste gas are discharged through the exhaust pipe 2 at the top, forming a virtuous cycle.

[0027] When the temperature and humidity sensor 11 detects that the humidity inside the chamber is lower than the set value, the humidifier 13 installed on the outside of the chamber 1 is activated, and the generated humid air is introduced into the chamber through the air duct 14 to quickly increase the humidity.

[0028] All the aforementioned environmental control actions are coordinated and controlled by the control panel 12. Users can preset the required temperature and humidity thresholds and light schemes for each growth stage of the tea seedlings on the control panel 12, and the system can then operate fully automatically, greatly reducing the difficulty of management.

[0029] The cultivation system adopts a layered design, with each layer containing a cultivation rack 3, a cultivation tray 5, and a seedling pot 6.

[0030] The cultivation rack 3 includes a fixed plate 3.1, which is fixed to the inner wall of the box 1 by positioning posts 3.2 at both ends. One end of the fixed plate 3.1 is connected to a water inlet pipe 3.3 at the top, and the other end has a water outlet pipe 3.4 at the bottom for bottom irrigation and drainage. The fixed plate 3.1 is a shallow water tank, and an external water storage tank 16 is connected to the water inlet pipes 3.3 of each layer via a water supply pipe 17. Both the water inlet pipe 3.3 and the water outlet pipe 3.4 are equipped with solenoid valves. During irrigation, the control panel 12 opens the water inlet solenoid valve, allowing water to flow into the fixed plate 3.1. When the water level in the plate reaches the height set by the level sensor 3.5, the water inlet solenoid valve closes, and immersion irrigation begins. Water slowly permeates from bottom to top into the entire substrate through the water outlet holes at the bottom of the seedling pot 6 and the permeable holes of the movable seat 7. This bottom irrigation method does not wash away the substrate or damage the seedling leaves. After irrigation, the water outlet solenoid valve is opened, and excess water is discharged through the drain pipe 15 to ensure no water accumulation. The liquid level observation window at the front end of the fixed plate 3.1 allows for manual observation of the water level.

[0031] The cultivation tray 5 is securely engaged within the fixing tray 3.1 via the positioning ring 5.2 at the bottom, while the handles 5.1 on both sides facilitate placement and removal. The seedling pot 6 adopts a frustum-shaped design, wider at the top and narrower at the bottom, with an outer limiting ring 6.1 ensuring stable placement within the positioning hole of the cultivation tray 5. This modular design allows for independent management and placement of individual tea seedlings, facilitating differentiated management and batch transplanting.

[0032] The lighting components 4 above each layer of the cultivation rack provide a flexible and suitable light source.

[0033] The sleeve 4.2 can slide along the crossbar 4.1 to adjust the lateral position of the LED light assembly. The gooseneck tube 4.4 is made of a high-strength, flexible, and shape-adjustable metal hose, allowing the protective cover 4.5 (containing a full-spectrum LED light 4.6) connected to its end to freely adjust the illumination angle and height in three-dimensional space. Whether it's necessary to evenly illuminate the entire tea seedling tray or to provide targeted supplemental lighting to weaker seedlings in specific areas, this can be easily achieved. After adjustment, tightening the set bolt at the front end of the sleeve 4.2 secures it. The dimming controller 4.7 at the front end of the protective cover 4.5 can precisely adjust the luminous intensity of the LED light 4.6 to meet the different light intensity requirements of the tea seedlings at different growth stages (such as budding and growth stages).

[0034] The non-destructive seedling extraction mechanism mainly consists of a seedling pot 6 and a movable seat 7.

[0035] During seedling cultivation, the top plate 7.2 of the movable seat 7 supports the planting substrate, and the permeable holes on the top plate 7.2 ensure that irrigation water can enter smoothly. During transplanting, the operator only needs to gently push the bottom plate 7.3 of the movable seat 7 upward from the bottom of the seedling pot 6 with their fingers. The vertical rod 7.1 moves vertically upward under the guidance of the limiting cylinder 6.2, thereby smoothly pushing the top plate 7.2 together with the entire substrate ball wrapped by the root system out of the seedling pot 6. This process completely avoids the damage to the tender roots caused by pulling the stems and leaves or prying the substrate in the traditional seedling removal method, and greatly improves the transplant survival rate and the speed of seedling recovery.

[0036] In practical use, the seedling pots 6 filled with substrate and tea seeds are placed into the cultivation tray 5, and then the cultivation tray 5 is placed on the fixed tray 3.1 inside the box 1. Suitable temperature, humidity, light cycle, and intensity parameters are set via the control panel 12. The temperature and humidity sensor 11 monitors in real time, and the control panel 12 automatically controls the humidifier 13 and ventilation components 10 (blower 10.1 and heating element 10.2) to maintain a stable environment. The light component 4 provides light according to the settings and can be flexibly adjusted. When water is supplied, the solenoid valve opens, and water enters the fixed tray 3.1 from the water storage tank 16 through the inlet pipe 3.3, stopping when the set liquid level is reached. The water permeates from bottom to top into the substrate. After the tea seedlings have grown to a certain stage, the box door is opened, the cultivation tray 5 is removed by holding the handle 5.1, and the tea seedlings with complete root systems can be easily removed for transplanting by lifting the movable seat 7 from the bottom.
