Description

Technical Field

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

[0002] In order to provide seedlings with a stable and controllable growth environment such as light, water and fertilizer, avoid the adverse effects of extreme weather, pests and diseases in the natural environment, improve seedling efficiency through centralized management, ensure uniform seedling growth, save land resources, meet the needs of large-scale and standardized seedling production, and lay a good foundation for subsequent transplanting and survival, seedling cultivation equipment is usually used.

[0003] Existing seedling cultivation requires a seedling cultivation device, the main structure of which includes a seedling tray (containing multiple seedling holes), a nutrient spraying system, a temperature control system (heating / cooling elements), a light module (LED seedling lamps), and a support frame. In use, the seedling substrate is filled into the seedling tray holes and sown. The seedling tray is placed on the support frame, and the prepared nutrient solution is injected into the nutrient solution storage tank. The spraying system is turned on, and the irrigation frequency and dosage are set. The temperature control module is adjusted to control the ambient temperature, and the light module is adjusted to regulate the light duration and intensity according to the crop's growth needs. Air circulation is maintained through ventilation holes. The seedling growth status is observed regularly, and nutrient solution is replenished and cultivation parameters are adjusted. Once the seedlings reach the transplanting standard, they can be removed.

[0004] However, existing seedling trays in seedling raising devices have the problem of making it difficult to remove seedlings. The main reason is that the holes in the seedling holes are too deep, making it difficult to reach them with fingers to push the seedlings out. During operation, tools are needed to remove each seedling from the seedling hole one by one (such as using a small wooden stick to push it out from the bottom of the hole). This is not only cumbersome, but also prone to damaging the seedlings or seedling trays due to improper force control. Therefore, we propose a seedling raising device to solve the problems encountered by existing technologies. Utility Model Content

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1:

[0032] Reference Figures 1 to 6 This is the first embodiment of the present invention. This embodiment provides a seedling cultivation device, including a glass chamber 1, in which seedling trays 2 are arranged in multiple layers, and seedling holes 6 are arranged in the seedling trays 2. A spray device 3, a temperature control device 4 and a seedling lamp 5 are arranged in the glass chamber 1. Each seedling tray 2 is provided with a seedling picking device 7 at its lower end. The seedling picking device 7 includes a push plate 72 arranged in the seedling hole 6. A bottom plate 71 is movably arranged at the lower end of the seedling tray 2 for driving the push plate 72 to move upward.

[0033] The glass chamber 1 provides a closed and controllable growth environment for seedling cultivation. The multi-layer seedling trays 2 and seedling holes 6 enable large-scale and centralized seedling cultivation. The spray unit 3 is used to spray nutrient solution or water to meet the seedlings' water and fertilizer needs. The temperature control unit 4 adjusts the ambient temperature to suit seedling growth. The seedling lamp 5 supplements the light to ensure photosynthesis. The seedling removal unit 7 drives the push plate 72 to move upward through the base plate 71, which can conveniently and smoothly push the seedlings out of the seedling holes 6, solving the problems of inconvenient seedling removal and easy damage to seedlings or seedling trays 2. The whole device realizes the cultivation of seedlings and convenient seedling removal.

[0034] It should be noted that the glass chamber 1 is equipped with temperature and humidity sensors, a controller, a spray system 3, a temperature control system 4, and a seedling lamp 5. The controller in the glass chamber 1 is electrically connected to the thermometer, hygrometer, and various components (the water pump of the spray system 3, the heater 41 and air conditioner 42 of the temperature control system 4, the seedling lamp 5, the exhaust fan 9, and the solenoid valve of the drain pipe). The controller presets threshold values ​​for parameters such as temperature, humidity, spray cycle, and light duration. During operation, it collects environmental data in the glass chamber 1 in real time through the thermometer and hygrometer. When the temperature is below the threshold, the heater 41 is activated; when it is above the threshold, the air conditioner 42 is activated. When the humidity is below the set value or reaches the spray cycle, the controller activates the water pump to make the spray head 32 work. At the same time, the solenoid valve controls the drain pipe to periodically discharge the liquid accumulated in the collection tank 8. The seedling lamp 5 automatically starts and stops according to the light duration set by the controller, and the exhaust fan 9 is activated by the controller in conjunction with the indoor humidity sensor, realizing automatic regulation of the environment inside the glass chamber 1 and ensuring stable operation of the controllable environment. This is existing technology, and the operating principle will not be described in detail.

[0038] The drainage pipe and solenoid valve facilitate the control of liquid discharge and recycling.

[0039] Specifically, Figure 1 In the middle, the inner wall of the liquid collection tank 8 is fixed with a filter plate 10 for placing the seedling tray 2 by bolts;

[0040] The filter plate 10 is used to support the seedling tray 2 and facilitate liquid seepage;

[0041] Specifically, Figure 2 In the middle, the spraying component 3 includes a liquid storage tank 31 fixed at the upper end of the glass chamber 1. A water pump is installed in the liquid storage tank 31, and the output end of the water pump is connected to three spray heads 32. The three spray heads 32 are respectively fixed to the top wall of the glass chamber 1 and the lower end of the liquid collection tank 8. The seedling lamp 5 is also fixed to the top wall of the glass chamber 1 and the lower end of the liquid collection tank 8.

[0042] Nutrient solution is stored in storage tank 31, and water pump drives the nutrient solution to spray onto each layer of seedling tray 2 through three spray heads 32; seedling lamp 5 provides light for each layer of seedlings.

[0043] Specifically, Figure 1 In the middle, the temperature control 4 includes a heater 41 and an air conditioner 42 fixed to the inner wall of the glass chamber 1;

[0044] The temperature inside the glass chamber 1 is regulated by a heater 41 and an air conditioner 42. The heater 41 and the air conditioner 42 are existing technologies, and their principles will not be described in detail.

[0045] Specifically, Figure 3 In the middle, each seedling tray 2 has a mounting frame 73 welded to its lower end. The mounting frame 73 has a screw 74 threaded inside, and the screw 74 is threaded with the center of the base plate 71 to drive the base plate 71 to rise and fall.

[0046] The mounting bracket 73 fixes the screw 74, which drives the base plate 71 to rise and fall.

[0047] Specifically, such as Figure 3 and Figure 4 In the middle, a plurality of connecting rods 75 are integrally provided on the upper surface of the base plate 71. The upper end of each connecting rod 75 passes through the lower end of the seedling tray 2 into the seedling hole 6 and is fixed to the lower surface of the push plate 72.

[0048] The base plate 71 and the push plate 72 are connected by a connecting rod 75 to achieve synchronous movement.

[0049] Example 3:

[0050] Reference Figure 3 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, Figure 3 In the middle, each push plate 72 is provided with multiple fan-shaped through slots 77;

[0052] The soil matrix is ​​embedded through the fan-shaped channel 77, which reduces soil loosening when taking seedlings.

[0053] Specifically, Figure 6 In the middle, the seedling hole 6 is set in a cone shape, the diameter of the bottom opening of the seedling hole 6 is smaller than the diameter of the top opening, and the bottom wall of the seedling hole 6 is provided with a circular through hole for draining liquid to the liquid collection tank 8;

[0054] The conical seedling hole 6, combined with the push plate 72, facilitates the ejection of seedlings, while the through holes in the bottom wall facilitate drainage.

[0055] Specifically, Figure 3 In the middle, a spring 76 is sleeved around the connecting rod 75. The upper end of the spring 76 is welded to the lower surface of the seedling tray 2, and the lower end of the spring 76 is welded to the upper surface of the base plate 71.

[0056] The base plate 71 is moved upward to compress the spring 76, and the spring 76 assists the base plate 71 in resetting.

[0057] Working principle: The seedling soil substrate is filled into the seedling hole 6 of the seedling tray 2 and sown. The soil substrate can penetrate into the fan-shaped through groove 77 of the push plate 72 to form an interlocking structure.

[0058] Then place the seedling tray 2 on the filter plate 10 of the liquid collection tank 8, inject the prepared nutrient solution into the liquid storage tank 31, turn on the exhaust fan 9 to keep the air in the glass chamber 1 circulating, start the water pump to make the spray head 32 spray the nutrient solution at the set frequency and dosage, adjust the temperature in the glass chamber 1 by the heater 41 and the air conditioner 42, turn on the seedling lamp 5 and adjust the light duration and intensity, observe the seedling growth status regularly, and drain the liquid accumulated in the liquid collection tank 8 through the drain pipe.

[0059] After the seedlings reach the transplanting standard, the seedling tray 2 is removed, and then the screw 74 is rotated to drive the base plate 71 to move upward. The base plate 71, through the connecting rod 75, drives the push plate 72 to move upward within the seedling hole 6, thereby pushing the seedlings in multiple seedling holes 6 to be removed simultaneously. The push plate 72 can form multi-point force support through the soil matrix embedded in the fan-shaped through groove 77, dispersing the pushing force to prevent soil collapse, while maintaining the soil aggregate structure and reducing excessive loosening of the soil when it is pushed out. This ensures the adhesion between the root system and the soil and the integrity of the root system. The spring 76 can assist the base plate 71 to return to its original position.
