[0001] This application relates to the field of agricultural production technology, and more particularly to a cultivation device. Background Technology

[0002] With the development of modern horticultural technology, cultivation devices are playing an increasingly important role in agricultural production, home gardening, and urban greening. Traditional cultivation devices typically consist of a cultivation trough, a cultivation substrate, and a simple cover. While this basic configuration meets basic planting needs, it has some limitations in practical applications. In soilless cultivation systems, nutrient solution is crucial for plant growth. However, existing cultivation devices are generally not designed to effectively retain and recycle nutrient solution, leading not only to waste but also potential environmental pollution due to leakage. Furthermore, existing cultivation devices lack effective insulation, making it difficult to maintain a stable ambient temperature for the cultivation substrate.

[0003] Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this application is to provide a cultivation device that can effectively reduce the waste of nutrient solution, improve resource utilization, make the cultivation device more practical, and maintain a stable temperature of the cultivation substrate, thereby improving cultivation efficiency.

[0005] To achieve the above objectives, this application provides a cultivation apparatus, comprising:

[0006] The cultivation trough has an upward-opening accommodating space, which is continuously arranged along the length of the cultivation trough and can be filled with cultivation substrate, which provides support and a growth environment for the roots of the cultivated plants.

[0007] A heat insulation layer is disposed between the cultivation trough body and the cultivation substrate to maintain the internal temperature of the containment space;

[0008] An isolation section with several fluid passages is disposed within the receiving space and abuts against the heat insulation layer to divide the receiving space into an upper first space and a lower second space. The cultivation substrate is filled in the first space, so that excess nutrient solution in the cultivation substrate can flow into the second space through the fluid passages for discharge and recycling of nutrient solution.

[0009] A heat-insulating cover is connected to the cultivation trough body from the opening end of the receiving space, and is used to seal the top opening of the cultivation trough body;

[0010] The substrate temperature control system includes a temperature regulating pipe, a temperature regulating device, and a control terminal. The temperature regulating device is connected to the temperature regulating pipe and the control terminal. The temperature regulating pipe is connected to the first space and separate from the second space, and is used to input a temperature regulating medium into the first space to regulate the growth temperature of the cultivation material. The control terminal is used to control the start and stop of the temperature regulating device, the output amount of the temperature regulating medium, and the output rate.

[0011] In some embodiments, the cultivation device includes a liquid circulation system, which includes an inlet pipe, an outlet pipe, a storage container, and a circulation pump. The inlet pipe is connected at both ends to the storage container and the first space, and the outlet pipe is connected at both ends to the storage container and the second space. Under the operation of the circulation pump, the nutrient solution flowing into the second space flows back into the storage container through the outlet pipe for storage or filtration. The nutrient solution in the storage container can be transported to the first space through the inlet pipe, thereby completing the recycling of the nutrient solution.

[0012] In some embodiments, the width of the cultivation trough body decreases monotonically from the opening of the accommodating space toward the bottom of the cultivation trough body, so that the cultivation trough body has a structural profile that is wider at the top and narrower at the bottom, in order to guide the flow of nutrient solution from the first space to the second space.

[0013] In some embodiments, the inner sidewall of the cultivation trough is provided with a limiting segment, which is provided along the length of the cultivation trough. The bottom of the isolation part indirectly abuts against the upper surface of the limiting segment to prevent further displacement of the isolation part.

[0014] In some embodiments, the cultivation trough has a bent edge that transitions to the opening of the accommodating space of the cultivation trough, the insulation layer fully covers the inner surface of the cultivation trough, and the edge of the insulation layer extends to the corresponding bent edge for mating, thereby increasing the contact area between the insulation layer and the cultivation trough through the bent edge.

[0015] In some embodiments, the heat-insulating cover is made of a flexible material, so that the heat-insulating cover can adaptively conform to the cultivation trough.

[0016] And / or, the material of the insulation layer is a waterproof and breathable material.

[0017] In some embodiments, the cultivation device further includes a support structure disposed below the cultivation trough body to support the cultivation trough body and position the cultivation trough body at a preset height.

[0018] In some embodiments, the support structure is a bracket type; the support structure includes several independently arranged support parts, which are equidistantly distributed. Each support part has a docking end at its upper part for connecting to the cultivation trough body, and a fixing end at its lower part for fixing the support part to a preset position.

[0019] In some embodiments, each of the support portions is provided with weight-reducing holes.

[0020] In some embodiments, the cultivation device is further provided with a suspension structure, which serves as a suspended support;

[0021] One end of the suspension structure is connected to the cultivation trough, and the other end is fixed at a preset position, so that the cultivation device can be suspended above the ground.

[0022] Compared with the prior art, the cultivation device provided in this application has the following beneficial effects:

[0023] 1. The cultivation device provided in this application effectively maintains the internal temperature of the cultivation space by setting a heat insulation layer between the cultivation trough and the cultivation substrate, providing a stable temperature-controlled environment for plant growth; the fluid perforation design of the isolation part realizes the collection and recycling of excess nutrient solution in the cultivation substrate, reducing the loss and waste of nutrient solution; and the airtight design of the heat insulation cover further enhances the control of the cultivation environment, improves resource utilization efficiency, and reduces the adverse effects of environmental factors on plant growth.

[0024] 2. The cultivation device provided in this application uses a liquid circulation system to circulate the nutrient solution between the first and second spaces, which reduces the waste of nutrient solution and improves the utilization rate. Since the nutrient solution can be recycled, the need for frequent replacement of nutrient solution is reduced, thereby reducing maintenance costs and labor intensity.

[0025] 3. The cultivation device provided in this application, by integrating temperature control equipment, temperature regulating pipes, and a control terminal, achieves precise control of the cultivation environment temperature, thereby significantly improving the quality and efficiency of plant growth. Specifically, the temperature regulating pipes act directly on the primary space containing the cultivation substrate, adjusting the temperature by inputting a temperature regulating medium to ensure that plants grow at the optimal growth temperature, thus promoting healthy plant development and increasing yield. Simultaneously, the introduction of the control terminal makes the temperature regulation process more intelligent and automated. Operators can precisely control the opening and closing of the temperature control equipment, the output quantity and rate of the temperature regulating medium according to the specific needs of the plants, achieving refined management of the cultivation environment.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] In traditional hydroponics systems, nutrient solution management is crucial for ensuring healthy crop growth. However, existing cultivation devices are often simply designed, typically consisting of only a cultivation trough, a growing medium, and a basic cover. While this basic configuration meets basic planting needs, it has some significant limitations in practical applications.

[0037] First, these simple cultivation devices often lack an effective nutrient solution circulation system, leading to nutrient loss and waste. Because there is no design to collect and reuse the nutrient solution flowing through the crop roots, these valuable nutrients are often directly lost, increasing planting costs and potentially polluting the environment. Furthermore, this loss results in crops not receiving a continuous and balanced supply of nutrients, affecting their growth and yield.

[0038] Another common problem in traditional hydroponics systems is the lack of an effective insulation layer, making it difficult to maintain a stable ambient temperature in the cultivation substrate. Due to the small volume of the substrate and its greater temperature fluctuations, it lacks the excellent heat retention properties of soil. Therefore, during the cold winters and hot summers, temperature fluctuations in the substrate significantly impact the growth of crop roots and their ability to absorb nutrients. Temperature is a crucial factor affecting plant growth; both excessively high and low temperatures can have adverse effects.

[0039] To address the problems in the prior art, referring to Figure 1 in the specification, the cultivation device provided in this application can effectively reduce the waste of nutrient solution, improve resource utilization, make the cultivation device more practical, and at the same time maintain the temperature of the cultivation substrate 5 stable, which is conducive to improving cultivation efficiency.

[0040] Referring to Figures 1 and 2 of the specification, the cultivation device provided in this application includes a cultivation trough body 1, a heat insulation layer 2, an isolation section 3, and a heat insulation cover 4. The cultivation trough body 1 has an upward-opening receiving space 10, which is continuously arranged along the length of the cultivation trough body 1 to accommodate cultivation needs of different lengths. The receiving space 10 within the cultivation trough body 1 is filled with cultivation substrate 5, providing necessary support and a suitable growth environment for the cultivated materials. The heat insulation cover 4 is connected to the open side of the receiving space 10 and closes with the cultivation trough body 1 to seal the top opening of the cultivation trough body 1. The design of the cover helps to further maintain the stability of the cultivation environment and prevent external factors such as dust and pests from interfering with the cultivation environment.

[0041] The heat insulation layer 2 is set between the cultivation trough body 1 and the cultivation substrate 5. Its main function is to reduce the impact of external temperature changes on the cultivation substrate 5, maintain the temperature stability inside the containment space 10, and create a more suitable environment for plant growth.

[0042] In this embodiment, the isolation section 3 is provided with several fluid through holes 300. The isolation section 3 is disposed within the receiving space 10 and abuts against the heat insulation layer 2. The isolation section 3 divides the receiving space 10 into an upper first space 101 and a lower second space 102, with the cultivation substrate 5 located in the first space 101. This design allows excess nutrient solution in the first space 101 to flow into the second space 102 through the fluid through holes 300, facilitating the discharge and recycling of the nutrient solution and reducing waste.

[0043] Optionally, in this embodiment, the cultivation trough 1 can be made of durable plastic or metal materials to ensure structural stability and durability. The size of the cultivation trough 1 can be adjusted according to cultivation needs to adapt to different scales of cultivation.

[0044] Additionally, it should be noted that in this embodiment, the heat insulation layer 2 can be directly laid inside the cultivation trough 1 to reduce heat exchange between the substrate and the external environment. This design is simple and direct, effectively isolating heat transfer from the ground or surrounding environment and maintaining a stable substrate temperature. Furthermore, the heat insulation layer 2 can be fixed to the inside of the cultivation trough 1 using fasteners (such as clips, adhesives, or straps). This fixing method ensures that the heat insulation layer 2 remains stable during cultivation and will not shift due to irrigation or substrate expansion and contraction.

[0045] Meanwhile, the choice of materials for insulation layer 2 is also diverse, including materials such as foam plastics, aerogel, and foamed cement boards. These materials have good thermal insulation properties and are lightweight and easy to process. To enhance the thermal insulation effect, a double-layer thermal insulation design can be adopted. For example, the outer layer can use reflective materials (such as aluminum foil) to reflect solar radiation, while the inner layer uses insulating materials (such as polystyrene foam) to reduce heat conduction.

[0046] Furthermore, the insulation layer 2 is designed with a waterproof and breathable material, a choice that offers multiple advantages and significantly enhances the performance of the cultivation device. Waterproof and breathable materials, such as polytetrafluoroethylene (PTFE) microporous membranes, possess a unique microporous structure. These micropores are small enough to prevent liquid water from passing through, yet large enough to allow water vapor molecules to permeate. The waterproof properties of this material effectively prevent the loss of nutrient solution and moisture, while its breathability helps maintain the necessary air exchange within the cultivation substrate 5, providing essential oxygen to the plant roots. Of course, in some other embodiments, the insulation layer 2 can also be an ePTFE membrane or a commercially available waterproof and breathable membrane.

[0047] Based on the above embodiments, more preferably, the material of the heat insulation cover 4 is a flexible material, so that the heat insulation cover 4 can adaptively fit the cultivation trough 1, ensuring a good seal at the interface between it and the cultivation trough 1, effectively isolating the influence of external temperature, and maintaining stable internal temperature. In addition, the flexible material makes the heat insulation cover 4 easy to install and adjust to adapt to cultivation troughs 1 of different shapes and sizes.

[0048] For example, this flexible heat-insulating cover 4 can be made of flexible rubber, silicone, or flexible plastic with heat-insulating properties. These materials have good elasticity and temperature resistance and can adapt to different shapes and sizes of cultivation troughs 1.

[0049] In some cases, the material of the heat insulation cover 4 can also be an opaque material, which can block light and provide a suitable growth environment for the roots, thus promoting healthy root growth. Specifically, the heat insulation cover 4 can be designed as a multi-layered structure, including a heat insulation layer 2 and an opaque layer, to improve both heat insulation and light blocking effects.

[0050] More importantly, the cultivation device also includes a substrate temperature control system, which includes a temperature control device, a temperature regulating pipe 7, and a control terminal. The temperature control device is connected to the temperature regulating pipe, and the control terminal is connected to the temperature control device. The temperature regulating pipe 7 is connected to the first space 101, i.e., the space where the cultivation substrate 5 is located, and avoids the second space 102. The temperature regulating pipe 7 is used to input a temperature-regulating medium into the first space 101 to adjust the growth temperature of the cultivated plants. The temperature-regulating medium can be a heating or cooling liquid, and can be adjusted to a heating or cooling mode according to different seasons and the needs of the plants.

[0051] The control unit is connected to the temperature control equipment and is used to control the opening and closing of the equipment. It also further controls the output quantity and rate of the temperature-regulating medium through the equipment. The control unit can be a manual control panel or an automated control system, such as an IoT-based intelligent control system, to achieve remote monitoring and precise control.

[0052] In this embodiment, the temperature of the cultivation substrate 5 can be precisely controlled by the cooperation of the temperature regulating pipe 7, the temperature regulating device, and the control terminal, so as to provide the best growth environment for the plants.

[0053] Based on this embodiment, as shown in Figure 1, the temperature regulating pipe 7 can be a circulating water system, using either cold or hot water to regulate the substrate temperature. In summer, cold water circulation can be used to lower the substrate temperature; in winter, hot water circulation can be used to raise the substrate temperature. The temperature regulating medium can be water or other liquids, such as antifreeze, depending on the local climate conditions and the temperature requirements of the plants.

[0054] In addition, the number of temperature regulating pipes 7 is greater than or equal to two, which are respectively input pipes and output pipes. The input pipes are used to input the temperature regulating medium, and the output pipes are used to output the temperature regulating medium that has participated in the temperature regulation work to the outside.

[0055] Furthermore, a temperature sensor is installed within the first space 101 to monitor the temperature of the cultivation substrate 5 in real time. If the cultivation trough 1 is long, multiple temperature sensors can be installed in different areas to ensure uniform temperature throughout the cultivation substrate 5. This allows for fine-tuning to meet the specific temperature requirements of different areas, improving the accuracy of temperature control.

[0056] Based on the above, in practical applications, operators can use the data collected by the temperature sensor to achieve closed-loop feedback control through the control terminal. When the temperature detected by the sensor deviates from the set value, the control terminal automatically adjusts the output of the temperature regulating medium, such as turning the heater on or off, or adjusting the flow rate of the cooling system, to maintain a constant growth temperature.

[0057] In one embodiment, the cultivation device includes a liquid circulation system, which mainly includes an inlet pipe 61, an outlet pipe 62, a liquid storage device, and a circulation pump.

[0058] One end of the inlet pipe 61 is connected to the storage container, and the other end is connected to the first space 101 of the cultivation trough. Its function is to transport the nutrient solution in the storage container to the first space 101 where the cultivation substrate 5 is located, providing the necessary nutrients for the plants. Similarly, one end of the outlet pipe 62 is connected to the storage container, and the other end is connected to the second space 102. When excess nutrient solution in the second space 102 flows into the storage container through the outlet pipe 62, the nutrient solution can be collected.

[0059] The liquid storage unit is a storage and filtration unit for the nutrient solution. It is connected to the inlet pipe 61 and the outlet pipe 62 and is used to store or filter the nutrient solution returning from the second space 102. The circulation pump is the power source of the liquid circulation system. It drives the nutrient solution to circulate between the liquid storage unit and the two spaces.

[0060] Understandably, in this embodiment, the nutrient solution can be collected, stored, and reused through the liquid circulation system, reducing waste of nutrient solution and improving resource utilization efficiency. Since the nutrient solution can be recycled, the need for frequent replacement of nutrient solution is reduced, thereby reducing maintenance costs and labor intensity.

[0061] In this embodiment, the circulation pump can be set near the liquid storage device or in any location that is easy to maintain, and the power and flow rate of the circulation pump should be selected according to the size of the cultivation tank 1 and the planting requirements. In addition, the liquid storage device can be a simple container, such as a plastic bucket, or a more complex filtration system, such as a water tank with filter media. The capacity of the liquid storage device should be determined according to the cultivation scale and the requirements of nutrient solution circulation.

[0062] Furthermore, an overflow port 63 is provided on the cultivation tank 1, as shown in Figure 2. The overflow port 63 serves as a second drainage channel to ensure that excess liquid can be discharged in time when the liquid level is high, thus avoiding waste of nutrient solution.

[0063] In conjunction with the above embodiments, during drip irrigation, the outlet pipe 62 is used to drain excess liquid; while during tidal irrigation, when the liquid volume exceeds a set level, the overflow port 63 serves as a second drainage channel to ensure that excess nutrient solution is drained and to prevent overflow. This design improves irrigation efficiency, reduces nutrient solution waste, and allows for flexible adjustment of irrigation strategies according to plant needs.

[0064] In some implementations, the outlet pipe 62 is designed to be closable, such as by being equipped with a valve, to control the discharge of liquid during drip irrigation.

[0065] The design of the outlet pipe 62 and the overflow port 63 allows for the selection of appropriate drainage paths based on different irrigation methods, thereby improving irrigation efficiency.

[0066] In one embodiment, based on the above embodiment, the width of the cultivation trough 1 gradually decreases from the opening of the accommodating space 10 towards the bottom of the trough, forming a structural profile that is wider at the top and narrower at the bottom. This design helps guide the nutrient solution flowing from the first space 101 to the second space 102, making its flow more orderly and uniform.

[0067] Specifically, please refer to the attached diagram in the instruction manual. Through this structural design, the nutrient solution is guided by the side wall of the tank during the flow from the first space 101 to the second space 102. This helps to guide the excess nutrient solution in the first space 101 to flow smoothly to the second space 102, reducing dead zones and stagnation zones in the nutrient solution during the flow process, thereby reducing the waste of nutrient solution and improving the utilization rate of nutrient solution.

[0068] The size and distribution of the fluid through-holes 300 on the isolation section 3 can be designed according to the type, texture, flow rate, and velocity of the nutrient solution to ensure that the nutrient solution can flow smoothly from the first space 101 into the second space 102. In some embodiments, the fluid through-holes 300 can be designed as grid-shaped holes, which helps to increase the flow area of ​​the fluid through-holes 300, thereby increasing the flow rate of the nutrient solution. They can also be designed as ordinary circular holes, etc.

[0069] In one embodiment, referring to Figures 1 and 2 of the specification, a limiting segment 11 is provided on the inner sidewall of the cultivation trough 1. The limiting segment 11 is provided along the length direction of the cultivation trough 1. In the above embodiment, the isolation part 3 is indirectly abutted against the upper surface of the limiting segment 11, effectively preventing further displacement of the isolation part 3.

[0070] Understandably, the limiting section 11 is designed to ensure the stability of the isolation section 3 inside the cultivation trough 1. The limiting section 11 provides a physical barrier for the isolation section 3, preventing accidental movement or detachment of the isolation section 3 and enhancing the stability of the entire cultivation device.

[0071] In the attached diagram, the limiting segments 11 are respectively set on the two opposite side walls of the cultivation trough 1, thereby forming a double-sided support for the isolation part 3. Of course, several independent point-like limiting segments can also be set on the side walls of the cultivation trough 1.

[0072] In one embodiment, as shown in Figure 2, the cultivation trough 1 has a bent edge 12, which is seamlessly connected to the opening of the accommodating space 10 of the cultivation trough 1, increasing the structural strength and stability of the cultivation trough 1. Simultaneously, the heat insulation layer 2 fully covers the inner surface of the cultivation trough 1, effectively isolating the external ambient temperature from the cultivation substrate 5.

[0073] More importantly, the edge of the insulation layer 2 extends to the corresponding bending edge 12 and mates with the bending edge 12, thereby increasing the contact area between the insulation layer 2 and the cultivation tank 1 through the bending edge 12, and enhancing the insulation effect; on the other hand, the mating of the edge of the insulation layer 2 with the bending edge 12 simplifies the installation process of the insulation layer 2, making it easier to fix the insulation layer 2 to the tank, reducing installation time and cost.

[0074] In addition, depending on the shape of the cultivation trough 1, one, two or more bent edges 12 can be designed. For example, for a rectangular trough, bent edges 12 can be set at the four corners; for a circular or elliptical trough, multiple bent edges 12 can be set at equal intervals along the edges; and for a trough similar to a triangular pyramid shape as shown in the attached figure, one bent edge 12 can be set on each of its long sides.

[0075] In one embodiment, the cultivation device further includes a support structure disposed below the cultivation trough 1 to support the cultivation trough 1 and position the cultivation trough 1 at a preset height.

[0076] The support structure provides a fixed foundation for the cultivation trough, ensuring the stability of the trough body 1 under different ground conditions and preventing tilting or collapse due to uneven ground. The support structure is fixed to the bottom of the cultivation trough by welding, bolting, or snap-fitting, ensuring the firmness and reliability of the installation.

[0077] The supporting structure can be made of metallic materials such as stainless steel or aluminum alloy to ensure strength and corrosion resistance. High-strength plastics can also be chosen to reduce weight and lower costs.

[0078] Optionally, adjustable feet can be designed at the bottom of the support structure to adapt to uneven ground and ensure that the cultivation trough 1 remains level at all times. Alternatively, casters can be integrated into the support structure to allow the cultivation trough 1 to be moved easily, thereby improving the flexibility and ease of operation of the cultivation trough 1.

[0079] Furthermore, referring to Figures 1 and 2 in the instruction manual, the support structure includes several independently arranged support parts 81, which are equidistantly distributed to ensure uniform support and stability of the cultivation trough 1. Each support part 81 has a connecting end at its upper part for connecting to the cultivation trough 1, and a fixing end 811 at its lower part for fixing the support part 81 to a preset position.

[0080] In Figure 1, the design of the fixed end 811 resembles a protrusion that can be inserted into the ground, ensuring stability and reliability after fixing. Additionally, the support part 81 can be designed as a height-adjustable structure to accommodate cultivation troughs 1 of different heights and different cultivation needs.

[0081] More preferably, each support 81 is provided with weight-reducing holes 810 to reduce the weight of the support 81, facilitating transportation and installation, while reducing material costs without affecting its structural strength and stability. The weight-reducing holes 810 can be designed in shapes such as circles, ellipses, or rectangles, and their distribution can be uniform or optimized according to structural strength requirements. The size and number of weight-reducing holes 810 are designed based on the material of the support 81 and the required strength.

[0082] In another embodiment, the cultivation device is provided with a suspension structure, which also serves as a suspension support. One end of the suspension structure is connected to the cultivation trough, and the other end is fixed to a preset position, such as to the ceiling, beam, or a special support frame, so that the cultivation device can be suspended above the ground. By suspending the cultivation device, ground space can be saved, which is particularly suitable for environments with limited space. On the other hand, the suspension structure can adjust the height and position of the cultivation device as needed to adapt to different cultivation needs and environmental conditions.

[0083] Alternatively, the suspension structure can be made of durable metal materials such as steel cables or high-strength plastics to ensure sufficient load-bearing capacity and stability; at the same time, the suspension structure can be designed as a simple hook type or a more complex pulley system to facilitate adjustment of the height and position of the cultivation device.

[0084] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
