Description

Technical Field

[0001] This utility model belongs to the technical field of forage planting equipment, specifically relating to an integrated cultivation device with zoned control function. Background Technology

[0002] Forage plant factories utilize indoor cultivation methods, combining advanced technologies such as irrigation systems, light regulation, and temperature control to provide a stable growth environment for forage. They often employ vertical planting and multi-layer stacking to increase yield per unit area. Their advantages include being unaffected by the natural environment and having a short growth cycle; requiring only water and light during planting, forage can grow to 15-20cm in about 7 days and can be used for feed supply, effectively solving problems such as insufficient forage supply, supply-demand mismatch, and restrictions on grazing. However, forage plant factories also face some challenges during operation:

[0003] Currently, most small and medium-sized plant factories use multi-layer cultivation racks, such as CN202222349310.7. While these racks offer high structural stability and durability, they suffer from drawbacks such as inconvenience in transportation and installation, difficulty in subsequent maintenance, and limited scalability. During operation, poor airflow design often leads to uneven temperature distribution and excessively high humidity across the cultivation layers, resulting in differences in the growth characteristics of forage in each layer, leading to insufficient moisture content, slow maturation, and low germination rates. The internal environment can only maintain a uniform setting, which is not ideal for forage at different growth stages or of different varieties, as they may require different growing conditions. When the forage is not fully loaded, the operating costs of the plant factory, including equipment and energy consumption, do not decrease proportionally with the reduction in forage planting. This significantly increases the production cost per unit of forage.

[0004] In particular, the environment inside the container can only maintain a uniform environmental setting. This environmental maintenance scheme makes it impossible to set the environmental parameters in different areas according to the actual growth needs of the forage, resulting in high forage production costs. Utility Model Content

[0005] This invention provides an integrated cultivation device with zoned control function, which aims to solve the problem that in the prior art, the environment inside the box can only maintain a uniform environmental setting, and the environmental parameters in different areas cannot be set according to the actual growth needs of the forage, resulting in high forage production costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An integrated cultivation device with zoned control function includes a box body;

[0008] The box is equipped with a cultivation rack assembly, which includes a frame and a cultivation board disposed on the frame.

[0009] The box is also equipped with a spray assembly, an air inlet assembly, an air return assembly, a planting light, and a control assembly. The spray assembly sprays water onto the plants on the cultivation board through branch spray pipes. Each branch spray pipe corresponds to a cultivation board, and each branch spray pipe is equipped with a spray control valve.

[0010] The air intake assembly includes an air intake branch pipe, which corresponds to the cultivation board. An air intake control valve is provided on the air intake branch pipe. The air return assembly includes a air return branch pipe, which corresponds to the cultivation board. A air return control valve is provided on the air return branch pipe. The planting light corresponds to the cultivation board.

[0011] The control component includes a temperature and humidity sensor that collects temperature and humidity within the cultivation board area, with each temperature and humidity sensor corresponding to a specific cultivation board. The control component also includes a pressure sensor that detects whether the cultivation board is unloaded, with each pressure sensor corresponding to a specific cultivation board. Furthermore, the control component includes a height sensor that detects the height of plants within the cultivation board, with each height sensor corresponding to a specific cultivation board. The control component also includes a controller, and the temperature and humidity sensor, pressure sensor, and height sensor are all communicatively connected to the controller. The planting light, air inlet control valve, air return control valve, and sprinkler control valve are all controlled by the controller.

[0012] A further improved solution: The box body includes a box bottom and a box top, a cylindrical sidewall is provided between the box bottom and the box top, the cylindrical sidewall is installed on the box bottom, the box top is installed on the cylindrical sidewall, and an entrance / exit is provided on the cylindrical sidewall.

[0013] Based on the above technical solution: the container consists of a bottom, cylindrical side walls, and a top. This modular design allows each part to be disassembled and assembled individually. During transportation, the device can be disassembled into smaller components, reducing space occupation and lowering transportation difficulty and cost. The cylindrical side walls and other structural components can be made of lightweight but high-strength materials, such as aluminum alloy or high-strength plastics. The use of lightweight materials not only reduces the overall weight of the device but also improves transportation efficiency and reduces energy consumption. By rationally designing the size and shape of the container, it becomes more compact and regular. The compact structure helps reduce space waste during transportation and increases the loading rate of transport vehicles.

[0014] A further improved solution: The frame includes a cultivation rack upright and a crossbar set on the cultivation rack upright. The cultivation board is installed on the crossbar. A convex connecting block is provided on the cultivation board. A concave receiving block that cooperates with the convex connecting block is provided on the crossbar.

[0015] Based on the above technical solution, the convex connecting blocks on the cultivation board and the concave receiving blocks on the crossbar form a clever fit. This design allows the cultivation board to be easily and quickly installed on the crossbar, and is also easy to disassemble. No complicated tools or operations are required; simply align the convex connecting block with the concave receiving block and gently push it in to complete the installation; disassembly is equally simple, requiring only a gentle pull. Despite the simplicity of installation and disassembly, the fit between the convex connecting block and the concave receiving block is very secure. This design ensures the stability of the cultivation board on the crossbar, preventing it from falling off or being damaged due to shaking or vibration. The stable connection also guarantees the stability and safety of the forage during its growth process.

[0016] A further improved solution: The air intake assembly further includes an air conditioning unit controlled by the controller. The air intake assembly also includes an air intake main duct, and the air intake branch duct is connected to the air conditioning unit through the air intake main duct. The air conditioning unit is provided with an air inlet and a return air inlet, and the return air inlet is connected to the air intake main duct. Alternatively, the air intake assembly further includes a distributor, which is provided with a distribution port connected to the air intake branch duct. The air intake branch duct is connected to the air conditioning unit through the distributor.

[0017] Based on the above technical solution: the air conditioning unit is controlled by a controller, which can precisely adjust parameters such as air temperature, humidity, and airflow speed delivered into the unit according to the actual needs of forage growth. This precise control helps meet the specific environmental parameter requirements of forage at different growth stages, thereby improving forage growth quality and yield. Through intelligent control of the air conditioning unit by the controller, the operating status of the unit can be dynamically adjusted according to the environmental conditions inside and outside the unit, avoiding unnecessary energy consumption. This energy-saving design helps reduce forage production costs and improve economic efficiency.

[0018] A further improved solution: The return air assembly also includes a return air riser and a return air main, and the return air branch is connected to the return air main through the return air riser.

[0019] Based on the above technical solution, the return air branch ducts connect to the return air main duct via return air risers, forming a highly efficient airflow channel. This design allows indoor air to be collected by the return air components more quickly, improving return air efficiency, reducing air stagnation time, and maintaining air freshness and cleanliness. By rationally setting the number and location of return air branch ducts, return air risers, and return air main ducts, uniform airflow distribution can be achieved. This helps avoid airflow short-circuiting or dead zones in certain areas, improving the overall ventilation effect of the space.

[0020] A further improved solution: A return air inlet is provided on the return air branch pipe, and a return air inlet is provided on the return air riser pipe, with the return air inlet and the return air inlet communicating with each other.

[0021] Based on the above technical solution, the interconnected design of the return air inlet and return air outlet allows air to smoothly enter the return air riser through the return air branch pipe. This design avoids airflow obstruction and accumulation in the duct, ensuring smooth and efficient airflow. By reducing airflow resistance and friction in the duct, energy consumption can be reduced, and the overall system energy efficiency can be improved.

[0022] A further improved solution: The spray assembly further includes a spray main pipe and a spray riser pipe, and the spray branch pipe is connected to the spray main pipe through the spray riser pipe.

[0023] Based on the above technical solution, the spray branch pipes are connected to the spray main pipe via the spray risers, ensuring that the spray water can be evenly distributed to all areas requiring spraying. This design helps avoid insufficient or excessive spraying in certain areas, thereby improving the coverage and uniformity of the spraying. By rationally setting the number and location of the spray risers and spray branch pipes, the spray intensity can be adjusted according to actual needs. In areas requiring strong spraying, the number of spray branch pipes and the density of spray nozzles can be increased, thereby improving the spraying effect.

[0024] A further improvement: The cultivation board is equipped with cultivation trays for cultivating plants.

[0025] Based on the above technical solutions: cultivation trays provide plants with independent growing spaces, ensuring that each plant receives relatively equal growing conditions. This helps avoid competition between plants and ensures the healthy growth of each plant. Cultivation trays can be placed individually or in groups on cultivation boards, facilitating the adjustment of environmental conditions such as light, temperature, and humidity according to the plant's growth needs. This flexibility helps meet the different requirements of various plants for their growing environment. Using cultivation trays simplifies plant management. For example, watering, fertilizing, and pest and disease control can be performed more precisely on each plant, reducing resource waste and environmental pollution. Cultivation trays are typically designed to maximize space utilization. Through proper placement and stacking, more plants can be grown on a limited cultivation board, improving space utilization.

[0026] A further improved solution: the cylindrical sidewall is welded to the bottom of the box, and the top of the box is welded to the cylindrical sidewall.

[0027] Based on the above technical solution: welding is a high-strength connection method. By welding, the cylindrical sidewalls are firmly connected to the bottom and top of the box, which can significantly improve the overall strength of the box. This strong connection allows the box to better maintain its shape and stability when subjected to external pressure or impact, and is less prone to deformation or damage.

[0028] A further improved solution: The entrance / exit is rotatably connected to the cylindrical sidewall via a hinge.

[0029] Based on the above technical solution: the door is connected to the cylindrical sidewall via hinges, allowing the door to easily switch between open and closed states. This design provides great convenience for users, especially when frequent entry and exit or adjustments to the interior environment are required. The rotating connection of the door does not occupy additional space when open, which is particularly important in space-constrained situations. For example, in small greenhouses or planting boxes, this design ensures that the door will not interfere with surrounding plants or equipment when open.

[0030] The beneficial effects of this utility model are as follows:

[0031] This invention avoids unnecessary resource waste through precise environmental parameter control. Under sufficient sunlight, the brightness of the planting lights can be reduced; when the temperature is suitable, the frequency of air intake and exhaust can be decreased. This resource optimization significantly reduces energy and water consumption, thereby lowering production costs.

[0032] Zonal regulation and intelligent control provide a more suitable growing environment for forage grasses and other plants, helping to improve their growth rate and quality. The device's control components achieve intelligent and automated management, automatically monitoring and adjusting environmental parameters, reducing the frequency and difficulty of manual intervention. This automated management method reduces labor intensity and improves management efficiency. Zonal regulation allows for zoned control based on the different growth stages of the forage grasses in different planting areas. Even under non-full-load operation, power supply to some areas can be cut off, achieving energy conservation and thus reducing the production cost of forage grasses.

[0033] The modular design of the device makes it easy to expand and upgrade. The scale of the device can be expanded by adding components such as cultivation boards, spraying components, and air intake components; the intelligence level and performance of the device can also be improved by upgrading components such as controllers and sensors.

[0034] The components are modular, which facilitates assembly, transportation, and manufacturing; they can be expanded as needed, reducing the difficulty and cost of maintenance for personnel, while improving system scalability.

[0035] The corresponding ducts can be combined with the cultivation racks to improve space utilization and improve the airflow pattern in the cultivation area; the addition of air conditioning units solves the problem of uneven air volume distribution in the ducts and optimizes the duct layout.

[0053] Specifically: The air intake assembly delivers the treated air to the distributor 403; the air intake main duct 5 and the air intake riser 501 are connected by a threaded connection, and the air intake riser 501 is connected to the air conditioning unit 4 by a bag-type connection, all made of stainless steel.

[0055] The working principle of this embodiment:

[0056] The treated seeds are placed in the cultivation tray. When the sensor detects that the cultivation plate 303 in that area is not empty, the planting program is started. The planting lights 9 and the air conditioning unit 4 operate automatically according to the set requirements to create a good planting environment. The sprinkler system can also spray the corresponding cultivation plate 303 according to the settings or sensor feedback information to prevent the forage from drying out. Once the forage plants reach the required height, a prompt message will appear.

[0057] During the growth of the forage, when the sensor detects that the cultivation plate 303 in that area is unloaded, the air intake control valve, sprinkler control valve, and planting lights 9 in that area are all closed to reduce unnecessary energy consumption. Temperature and humidity sensors collect temperature and humidity data for the corresponding area. When the outdoor temperature is higher than the indoor temperature, the air conditioning unit 4 automatically adjusts to cooling mode; conversely, it switches to heating mode, while also maintaining a manual mode. When the pressure sensor detects that the planting tray 8 in the area is not unloaded, the planting mode is activated. Based on the temperature and humidity data collected by the temperature and humidity sensors in the corresponding area, if the temperature in the area is higher than the set temperature, the air intake control valve opens, allowing cold air to enter the cultivation area for cooling; if the temperature in the area is lower than the set temperature, the air intake control valve opens, allowing hot air to enter the cultivation area for cooling; if the humidity in the area is lower than the set humidity, the sprinkler control valve opens to humidify the cultivation area; if the humidity in the area is higher than the set humidity, the return air control valve opens to accelerate airflow circulation in the cultivation area and reduce humidity. The planting lights 9 can be set for specific time periods according to user needs, or can be set according to system defaults.

[0058] When the height sensor detects that the pasture has reached the harvest height, it sends a message to the user. At the same time, the height sensor uploads daily pasture growth height data, temperature and humidity data, etc. to the cloud. Users can view the data at any time and remotely control parameters such as temperature and humidity.
