The control module 5 is used to adjust the output flow rate of the fertigation mixture.

[0055] In this embodiment, a citrus hydrating and fertilizing device includes a storage tank 1, a mixing mechanism 2, a conveying pipeline 3, and a control module 5. The storage tank 1 has a water inlet 11 and a feed inlet 12 at its top. The water inlet 11 is used to inject water into the storage tank 1, and the feed inlet 12 is used to add fertilizer or other additives into the storage tank 1. The bottom of the storage tank 1 has an outlet 13 for discharging the mixed hydrating and fertilizing solution. The storage tank 1 is typically made of chemically resistant and wear-resistant materials, such as polyethylene, polypropylene, or stainless steel. The mixing mechanism 2 is installed inside the storage tank 1. The mixing mechanism 2 consists of multiple sets of stirring components 21 and radial dispersing rods 22. The stirring components 21 are responsible for mixing water and fertilizer, while the radial dispersing rods 22... Two components are installed on the outer surface of the mixing assembly 21 to enhance the mixing effect and ensure the uniformity of the water-fertilizer solution. One end of the delivery pipeline 3 is connected to the outlet 13 of the storage tank 1, and the other end is connected to the spray head 4, forming a delivery channel for the water-fertilizer solution. A pH sensor 31 is installed at the outlet 13. The pH sensor 31 is a sensor that can measure the acidity and alkalinity (pH value) of a liquid. The pH sensor 31 converts the chemical signal into an electrical signal and transmits it to the control module 5 to monitor the acidity and alkalinity of the water-fertilizer mixture and ensure that the water-fertilizer mixture is suitable for citrus growth. The control module 5 can adjust the output flow rate of the water-fertilizer mixture according to the feedback from the pH sensor 31 and the preset parameters to achieve precise fertilization.

[0056] In this embodiment, the citrus fertigation device can significantly improve fertilizer utilization, reduce fertilizer waste, and lower planting costs by precisely controlling the water-fertilizer mixing ratio and output flow rate. The use of pH sensor 31 ensures that the acidity and alkalinity of the fertigation solution are suitable, which is conducive to the healthy growth of citrus and improves fruit quality. The intelligent control module 5 can automatically adjust the fertilization strategy according to real-time data, reduce manual intervention, and save labor. The integrated design simplifies the fertilization process, improves the convenience and efficiency of operation, and makes citrus planting more modern and intelligent.

[0057] Please see Figure 2 , Figure 3 In some embodiments, the stirring assembly 21 includes a power mechanism 211, a rotating rod 212, and stirring blades 213; the power mechanism 211 is a drive motor, which is placed on top of the liquid storage tank 1, and the power mechanism 211 is electrically connected to the control module 5; the rotating rod 212 is connected to the power mechanism 211 via a coupling; the stirring blades 213 are arranged at a certain radial angle with the rotating rod 212.

[0058] In this embodiment, the stirring assembly 21 includes a power mechanism 211, a rotating rod 212, and stirring blades 213. The power mechanism 211, i.e., the drive motor, is typically placed on top of the storage tank 1, which helps save space and facilitates maintenance and operation. The power mechanism 211 is electrically connected to the control module 5, i.e., the control module 5 is connected to the power mechanism 211 via wires or cables to realize the transmission of power and control signals, ensuring precise control and adjustment of the stirring process. The rotating rod 212 is the component connecting the power mechanism 211 and the stirring blades 213, and the rotating rod 212 is connected by a coupling. The stirring blade 213 is connected to the power mechanism 211, allowing power to be transmitted smoothly and effectively to the stirring blade 213. The stirring blade 213 is set at a certain angle to the radial direction of the rotating rod 212. It can be understood that the stirring blade 213 can cover a larger stirring area when rotating, thereby improving the stirring efficiency. The precise setting of the angle ensures that the stirring blade 213 can generate sufficient shear force during rotation to achieve uniform mixing of the liquid. Preferably, the shape and size of the stirring blade 213 are also preset to adapt to specific stirring tasks, whether it is dispersing solid particles or mixing liquids of different densities.

[0059] In this embodiment, due to the electrical connection between the power mechanism 211 and the control module 5, the stirring process can be precisely controlled according to actual needs, which not only improves stirring efficiency but also helps save energy. The use of the coupling reduces vibration and noise, making the stirring process more stable and extending the service life of the stirring assembly 21. The angled stirring blades 213 can provide better mixing effect, which is especially important for fertilization processes that require precise mixing. In addition, the stirring assembly 21 has good adaptability and can be adjusted according to different stirring needs, so that the stirring assembly 21 can perform well in a variety of application scenarios. In summary, this design of the stirring assembly 21 improves stirring efficiency, reduces energy consumption, and also improves the reliability and durability of the equipment.

[0060] Please see Figure 2 In some embodiments, an annular guide plate 14 is provided on the inner wall of the liquid storage tank 1, and the annular guide plate 14 is inclined.

[0061] In this embodiment, an annular guide plate 14 is provided on the inner wall of the liquid storage tank 1. The annular guide plate 14 is arranged in a ring along the inner wall of the liquid storage tank 1. Its purpose is to guide the liquid to flow along a specific path, thereby promoting the circulation of the liquid inside the liquid storage tank 1 and improving the flow characteristics of the liquid in the liquid storage tank 1. The annular guide plate 14 is inclined. It can be understood that the angle of inclination can make the liquid generate a centripetal force during the flow process, which helps the liquid form an effective vortex in the liquid storage tank 1 and enhances the mixing effect. The material of the annular guide plate 14 needs to be a wear-resistant material to ensure that the annular guide plate 14 can withstand long-term use without deformation or damage.

[0062] In this embodiment, the inclined annular guide plate 14 can effectively promote the circulation of liquid within the storage tank 1, helping to achieve faster and more uniform mixing, especially when mixing liquids of different densities or viscosities; it reduces dead zones in liquid flow, preventing liquid deposition at the edge of the storage tank 1; due to the improved mixing efficiency, the operating time of the stirring assembly 21 can be reduced, thereby saving energy and reducing equipment maintenance costs; it also helps to reduce friction between the liquid and the inner wall of the storage tank 1, which not only reduces wear on the storage tank 1 but also lowers the noise level of the equipment, improving the working environment; it improves mixing efficiency, reduces energy consumption and maintenance costs, and improves the operating environment.

[0063] Please see Figure 4 In some embodiments, the delivery pipeline 3 includes a flow sensor 32 and an electric valve 33, which are electrically connected to the control module 5.

[0064] In this embodiment, the delivery pipeline 3 not only includes a traditional pipeline structure but also integrates two components: a flow sensor 32 and an electric valve 33. The flow sensor 32 is responsible for real-time monitoring of the flow of the water-fertilizer mixture to ensure accurate flow measurement. The electric valve 33 is used to adjust the flow in the pipeline according to control signals, thereby achieving precise control of the water-fertilizer mixture output. The flow sensor 32 is a device for monitoring the liquid flow in the pipeline, capable of measuring and providing real-time information on the rate at which the liquid flows through the pipeline. The flow sensor 32 is crucial for controlling and regulating the liquid flow, ensuring that the liquid is delivered at a predetermined flow rate. The electric valve 33 is a device that controls the opening and closing of the valve via an electric actuator, and can adjust the flow according to control signals. The automatic regulating valve 33 controls the flow rate of liquid in the pipeline. The electric valve 33 enables precise flow control and is a commonly used component in automated systems. Both the flow sensor 32 and the electric valve 33 are electrically connected to the control module 5, allowing the control module 5 to adjust the opening of the electric valve 33 based on real-time data, optimizing the output flow rate of the water-fertilizer mixture and ensuring the uniformity and efficiency of the fertilization process. The electrical connection refers to connecting the flow sensor 32 and the electric valve 33 to the control module 5 via wires or cables, enabling the transmission of power and control signals. This allows the control module 5 to remotely control the electric valve 33 and receive data from the flow sensor 32 in real time, achieving automated control of the entire conveying system.

[0065] In this embodiment, the real-time monitoring function of the flow sensor 32 enables the control module 5 to accurately grasp the flow status of the water-fertilizer mixture, which is crucial for ensuring the uniformity and precision of fertilization. The precise control capability of the electric valve 33 allows the amount of fertilizer to be adjusted according to the actual needs of the citrus, avoiding over- or under-fertilization, thereby improving fertilizer utilization and the growth quality of the citrus. It also helps to reduce resource waste and environmental pollution by allowing for more refined fertilization management. The electrical connection with the control module 5 allows the entire system to be easily integrated into a smart agriculture system, realizing automated and intelligent fertilization operations, improving work efficiency, and reducing labor intensity.

[0066] Please see Figure 4 In some embodiments, the spray head 4 includes a rotating connector 41 and a fan-shaped spray panel 42; the rotating connector 41 is threadedly connected to the delivery pipeline 3; the fan-shaped spray panel 42 is provided with a group of spray holes 421.

[0067] In this embodiment, the spray head 4 consists of two parts: a rotating connector 41 and a fan-shaped spray panel 42. The spray head 4 is the terminal device of the liquid delivery system, used to spray the mixed water and fertilizer in a specific pattern. The spray head 4 directly affects the uniformity of water and fertilizer distribution and the spraying efficiency. The rotating connector 41 is the connection device between the spray head 4 and the delivery pipeline 3. The rotating connector 41 is connected to the delivery pipeline 3 by threads. The threaded connection provides a firm connection and allows the spray head 4 to rotate within a certain range. It can be understood that the rotating connector 41 allows the spray head 4 to rotate freely within a certain angle range to adapt to different spraying directions and coverage areas, so that the spray head 4 can... The spraying angle can be adjusted according to actual needs to ensure that water and fertilizer can be evenly covered in the target area. The fan-shaped spraying panel 42 is the core part of the spray head 4. The fan-shaped spraying panel 42 is fan-shaped to achieve a wide spraying range. Multiple spray hole groups 421 are evenly distributed on the fan-shaped spraying panel 42. The spray hole groups 421 are responsible for spraying water and fertilizer in a fan-shaped pattern. The size, number and distribution of the spray holes in the spray hole group 421 take into account the pressure and flow rate of the liquid to ensure that the sprayed water and fertilizer can form a uniform mist or water droplets, thereby improving the coverage efficiency and penetration effect of water and fertilizer application. The spray head 4 precisely controls the spraying mode and direction of water and fertilizer to adapt to different agricultural spraying needs.

[0068] In this embodiment, the rotating connector 41 allows the spray head 4 to adjust the spraying direction as needed, which not only improves the flexibility of spraying but also helps reduce liquid waste and ensures that the liquid can be accurately sprayed to the target area. The fan-shaped spray panel 42 allows the spray head 4 to cover a wider area, reducing the possibility of repeated spraying and improving work efficiency. The uniform distribution and precise design of the spray hole group 421 ensures that the sprayed liquid is evenly distributed, which is crucial for the uniform growth of citrus and the effective coverage of water and fertilizer. It also helps to reduce manual operation and labor intensity. Especially in large-area farmland operations, the spray head 4 can significantly improve work efficiency and save time and costs. In summary, it improves the uniformity and efficiency of liquid spraying, reduces resource waste, and enhances the economic benefits of agricultural operations.

[0070] In this embodiment, a level gauge 15 is installed inside the storage tank 1. The level gauge 15 is an instrument used to measure the liquid level inside the storage tank 1. It can be mechanical, electronic, or ultrasonic, etc. The level gauge 15 is used to monitor the liquid level in the tank in real time to ensure that it will not overflow due to overfilling or affect use due to underfilling. A sedimentation tank 16 is provided at the bottom of the storage tank 1 to collect solid impurities or sediments that may settle at the bottom of the tank, preventing solid impurities or sediments from re-mixing into the liquid and affecting the purity of the liquid and its subsequent use. A backflushing port 17 is provided on the side wall of the sedimentation tank 16, which allows for operation. The authors introduced reverse water flow or other cleaning media to remove sediment from the sedimentation tank 16, preventing excessive sediment accumulation and maintaining the cleanliness and efficient operation of the system. The bottom of the sedimentation tank 16 is connected to the outside via a slag discharge pipe 18. A slag discharge valve 19 installed on the slag discharge pipe 18 is used to control the discharge of sediment. It can be understood that when the sedimentation tank 16 needs to be cleaned, the slag discharge valve 19 can be opened to discharge the sediment; when cleaning is not required, the slag discharge valve 19 is closed to prevent liquid leakage or sediment backflow, ensuring that sediment can be easily removed when needed without polluting the surrounding environment.

[0071] In this embodiment, the level gauge 15 allows the operator to precisely control the liquid storage volume, avoiding waste and overflow; the sedimentation tank 16 and backflushing port 17 effectively prevent the re-suspension of solid impurities, ensuring the cleanliness of the liquid, which is especially important for applications requiring high-purity liquids; the slag discharge pipe 18 and slag discharge valve 19 make the cleaning of sediments simple and quick, reducing manual operation and lowering maintenance costs and time; it also helps extend the service life of the storage tank 1 by reducing the corrosion and wear of the tank body by internal sediments; overall, it improves the efficiency and safety of liquid handling and reduces the complexity of operation and maintenance.

[0073] In this embodiment, the control module 5 integrates three key functions: a liquid level monitoring unit 51, a pH adjustment unit 52, and a communication unit 53. The control module 5 is responsible for receiving data from different monitoring units and executing corresponding control commands based on this data. The liquid level monitoring unit 51 is a part of the control module 5 specifically used to monitor the liquid level in the storage tank 1. The liquid level monitoring unit 51 is electrically connected to the liquid level gauge 15 inside the storage tank 1 to obtain liquid level information in real time, ensuring that the liquid is maintained at a safe and effective level. The pH adjustment unit 52 is a part of the control module 5 used to monitor and adjust the pH of the liquid. The pH adjustment unit 52 is electrically connected to the pH sensor 31 at the outlet 13. The pH sensor 31 is a sensor capable of measuring the pH of a liquid; it converts chemical signals into electrical signals and transmits them... The data is fed to control module 5 to monitor the pH of the water-fertilizer mixture. Control module 5 can adjust the pH of the water-fertilizer mixture based on feedback from pH sensor 31 and preset parameters. It can also automatically adjust the pH value through the control algorithm in the adjustment unit to ensure that the pH of the mixture meets the optimal conditions for crop growth and satisfies specific application requirements. Communication unit 53 is the part of control module 5 used for data transmission and reception. Communication unit 53 allows control module 5 to communicate with remote devices or control systems, transmitting control commands and receiving feedback information through wireless or wired networks to achieve remote monitoring and operation. It can be understood that communication unit 53 sends and receives control commands through networks (such as wireless networks, the Internet, etc.) to help remote operators remotely operate and monitor control module 5, and then control and operate the entire fertilization device through the operation of control module 5.

[0074] In this embodiment, the inclusion of control module 5 enhances the system's automation and ease of operation. The integration of liquid level monitoring unit 51 and pH adjustment unit 52 enables control module 5 to automatically adjust the liquid level and pH of the water-fertilizer mixture, reducing manual intervention and the possibility of operator errors. The addition of communication unit 53 allows the fertilization equipment to be remotely controlled, enabling operators to monitor and adjust the system status without being physically present, thus improving management efficiency. It also helps improve the accuracy and uniformity of fertilization, as the operation module can automatically adjust based on real-time data to ensure that crops receive appropriate water and fertilizer supply. Overall, this contributes to improving crop yield and quality while reducing resource waste and achieving the goals of precision agriculture.

[0075] Please see Figure 5 In some embodiments, the outer surface of the delivery pipeline 3 is covered with a solar heating film 34.

[0076] In this embodiment, the outer surface of the conveying pipeline 3 is covered with a solar heating film 34.

The solar heating film 34 is usually made of special materials, such as graphene or other materials with high photothermal conversion efficiency, which can use the absorbed solar energy to heat the liquid in the pipeline.

[0077] In this embodiment, the solar heating film 34 improves the sustainability of energy utilization. By utilizing solar energy, a clean and renewable energy source, it reduces dependence on fossil fuels, helps reduce greenhouse gas emissions, and has a positive impact on environmental protection. The application of the solar heating film 34 reduces the operating cost of the delivery pipeline 3, reduces the demand for external heat energy input, and allows the output mixed water-fertilizer liquid to maintain a certain temperature, which is more suitable for citrus growth. It also improves the efficiency and reliability of the system, reduces energy waste due to heat loss, and ensures temperature control of the liquid during the delivery process. In summary, it not only improves energy utilization efficiency but also helps to achieve green and low-carbon sustainable development goals.
