[0013] In a preferred embodiment, a pressure gauge is fixedly installed on the upper surface of the mixing tank, and an observation window is fixedly installed on the upper surface of the pressure gauge.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the diversion and docking assembly serves as the central distribution hub for water and fertilizer transport. It receives the water and fertilizer mixture output from the water and fertilizer mixing assembly and precisely distributes the water and fertilizer to the corresponding slow-release supply assemblies for each tree through internal components, achieving centralized distribution and targeted transport of water and fertilizer. The slow-release supply assembly, as the water and fertilizer supply unit of the device, is buried in the root zone of the trees and receives the water and fertilizer transported by the diversion and docking assembly. Through the cooperation of multiple internal structures, it achieves long-term, slow, and uniform release of water and fertilizer to the rhizosphere soil. The water and fertilizer mixing assembly, as the mixing, stirring, and storage component, completes the mixing of water, fertilizer, and pesticides to prepare a water and fertilizer mixture with uniform concentration, providing a stable source of water and fertilizer for the entire device. The booster pump is used to pressurize the water and fertilizer within the diversion and docking assembly. The pump provides power to increase the pressure of water and fertilizer delivery, ensuring that water and fertilizer can be smoothly delivered to the slow-release supply assemblies at various remote locations. The diversion pipeline, as the main water and fertilizer delivery pipeline, is used to connect with various branch pipelines to achieve the initial diversion of water and fertilizer from the booster pump to multiple branches. The electric control valve is installed at the front end of the branch pipeline and controls the opening and closing of a single branch pipeline and the amount of water and fertilizer delivered through electric control. The branch pipeline connects the electric control valve to the coupling interface inside the soil protection box, delivering the diverted water and fertilizer to each corresponding slow-release supply assembly. It is the final delivery pipeline of water and fertilizer. The soil protection box is fitted on the docking part of the coupling interface and the coupling joint and buried in the shallow ground layer to isolate the coupling interface from the soil, roots, and debris, forming an independent clean docking space.
[0015] 2. In this invention, the coupling interface serves as the end connection component of the diversion and connection assembly, adsorbing and engaging with the coupling connector of the slow-release supply assembly to achieve rapid connection and disconnection between the water and fertilizer delivery pipeline and the buried supply component. It is the connecting node for water and fertilizer delivery. The guide rod provides guidance and positioning for the connection between the coupling interface and the coupling connector, ensuring precise alignment during connection and preventing connection failure or water and fertilizer leakage due to misalignment. The upper cover plate covers the upper surface of the soil-proof protection box, and the sealing ring on the outer surface of the upper cover plate seals the upper end of the soil-proof protection box, preventing surface soil, rainwater, and debris from entering the soil-proof protection box and contaminating the connection component. The coupling connector, as the top connection component of the slow-release supply assembly, adsorbs and engages with the coupling interface, achieving pipeline connection between the diversion and connection assembly and the slow-release supply assembly, thus facilitating water and fertilizer delivery. Upon entering the buried housing, the guide block engages with the guide rod to provide auxiliary guidance for the docking of the guide block and the coupling interface, ensuring precise alignment and preventing adsorption failure due to misalignment. This also improves assembly and disassembly efficiency. The buried housing, as the main structure of the slow-release supply assembly, is a buried design that integrates various water and fertilizer storage and slow-release components. It protects the internal components from soil compression and corrosion, serving as a carrier for long-term slow-release water and fertilizer. By installing easily disassembled buried supply components on the existing device, the buried supply unit can be conveniently installed, inspected, and replaced simply by digging up the surface soil, without the need for transfer. Individual supply components can also be replaced separately to adapt to the planting needs of different tree ages and plots, avoiding the abandonment of the entire unit.
[0016] 3. In this invention, the water storage chamber is located at the upper end of the buried shell, storing the water-fertilizer mixture entering from the coupling joint, continuously providing water to the slow-release fertilizer core cavity, ensuring the continuity of water-fertilizer slow release. The water storage chamber is located at the lower end of the buried shell, used to place the solid slow-release fertilizer core, receiving the water permeated from the water storage chamber, allowing the fertilizer to slowly and evenly dissolve to form fertilizer solution, which is the main area for nutrient slow release. The permeation baffle controls the water in the water storage chamber to slowly and evenly permeate into the slow-release fertilizer core cavity, regulating the rate at which water wets the fertilizer. The anti-settlement base increases the contact area between the buried shell and the soil, providing stable support for the slow-release supply assembly, preventing the shell from tilting, sinking, or shifting due to soil settlement and compression. The microporous permeation panel provides a release channel for the fertilizer solution in the slow-release fertilizer core cavity, allowing the fertilizer solution to slowly and evenly permeate into the rhizosphere soil through the micron-level micropores on the panel. The anti-clogging filter screen is wrapped around the outside of the microporous permeation panel, further blocking soil particles, forest fruit roots, and weed roots from entering the microporous permeation panel, preventing them from being blocked.

The other end of the coupling connector 21 is fixedly installed and embedded in the shell 23. The diversion and docking assembly 1 serves as the transfer and distribution core for water and fertilizer transportation. It receives the water and fertilizer mixture output from the water and fertilizer mixing assembly 3 and accurately distributes the water and fertilizer to the corresponding slow-release supply assembly 2 for each tree through internal components, realizing centralized distribution and directional transportation of water and fertilizer. The slow-release supply assembly 2 serves as the water and fertilizer supply unit of the device and is buried in the root area of the tree. The water and fertilizer supplied by Assembly 1 are released into the rhizosphere soil in a long-term, slow, and uniform manner through the coordination of multiple internal structures. The water and fertilizer mixing assembly 3 serves as the mixing, stirring, and storage component, completing the mixing of water, fertilizer, and pesticides to prepare a uniformly concentrated water and fertilizer mixture, providing a stable source of water and fertilizer for the entire device. The booster pump 11 provides power for the transport of water and fertilizer within the distribution assembly 1, increasing the transport pressure and ensuring smooth delivery of water and fertilizer to the remote slow-release supply assemblies 2. The branch pipe 12 serves as the main water and fertilizer transport pipeline, connecting to various branch pipes 14 to achieve… Water and fertilizer are initially diverted from the booster pump 11 to multiple branches. The electric control valve 13 is installed at the front end of the branch pipe 14 and controls the opening and closing of a single branch pipe 14 and the amount of water and fertilizer delivered through electric control. The branch pipe 14 is connected to the coupling interface 16 inside the electric control valve 13 and the soil protection box 15, and delivers the diverted water and fertilizer to each corresponding slow-release supply assembly 2. It is the final delivery pipeline of water and fertilizer. The soil protection box 15 is fitted at the docking part of the coupling interface 16 and the coupling connector 21 and buried in the shallow ground layer to isolate the coupling interface 16 from the soil, roots and debris, forming an independent clean docking space.
[0021] The coupling interface 16 serves as the end connection component of the diversion and connection assembly 1, engaging with the coupling connector 21 of the slow-release supply assembly 2 to achieve rapid connection and disconnection between the water and fertilizer delivery pipeline and the buried supply component. It is the connecting node for water and fertilizer delivery.

The inlet is where water and fertilizer enter the buried housing 23. The guide block 22 can cooperate with the guide rod 17 to provide auxiliary guidance for the docking of the guide block 22 and the coupling interface 16, ensuring that the two fit together accurately and avoid adsorption failure due to misalignment. At the same time, it improves the efficiency of disassembly and assembly. The buried housing 23 is the main structure of the slow-release supply assembly 2. It is a buried design and integrates various water and fertilizer storage and slow-release components. It protects the internal components from soil compression and corrosion and is the carrier for long-term slow release of water and fertilizer. By installing the buried supply components that are easy to disassemble in the existing device, the buried supply device can be easily installed, inspected and replaced by simply digging out the surface soil without the need for transfer. At the same time, individual supply components can be replaced individually to adapt to the planting needs of different tree ages and different plots, avoiding the abandonment of the whole system.

The water storage chamber 24 is located at the upper end of the embedded shell 23 and stores the water-fertilizer mixture entering from the coupling joint 21, continuously providing water to the slow-release fertilizer core chamber 25 to ensure the continuity of water-fertilizer slow release. The water storage chamber 24 is located at the lower end of the embedded shell 23 and is used to place the solid slow-release fertilizer core, receiving the water that permeates from the water storage chamber 24, so that the fertilizer slowly and evenly dissolves to form fertilizer solution, which is the main area for nutrient slow release.

An anti-settlement base 29 is fixedly installed on the lower surface of the shell 23. The seepage baffle 26 controls the water in the water storage chamber 24 to slowly and evenly seep into the slow-release fertilizer core chamber 25, and adjusts the rate at which water wets the fertilizer. The anti-settlement base 29 increases the contact area between the buried shell 23 and the soil, providing stable support for the slow-release supply assembly 2 and preventing the shell from tilting, sinking, or shifting due to soil settlement and compression.

The gate valve pipe 38 connects the mixing tank 33 and the filter box 39 and is used to transport the prepared water-fertilizer mixture in the mixing tank 33 to the inside of the filter box 39. At the same time, the gate valve pipe 38 contains a gate valve to control the flow rate of the water-fertilizer mixture discharged from the mixing tank 33 to the filter box 39. The filter box 39 filters the water-fertilizer mixture to remove undissolved fertilizer particles, impurities, etc. in the fertilizer solution and prevent impurities from entering the pipeline and the slow-release supply assembly 2 and causing blockage.

[0031] Working principle: The booster pump 11 provides power for the delivery of water and fertilizer within the diversion assembly 1, increasing the water and fertilizer delivery pressure to ensure smooth delivery of water and fertilizer to each remote slow-release supply assembly 2. The diversion pipe 12 serves as the main water and fertilizer delivery pipeline, connecting to each branch pipe 14 to achieve initial diversion of water and fertilizer from the booster pump 11 to multiple branches. The electrically controlled valve 13 is installed at the front end of the branch pipe 14, controlling the on / off state of each branch pipe 14 and the water and fertilizer delivery volume via electrical control. The branch pipe 14 connects the electrically controlled valve 13 to the coupling interface 16 inside the soil protection box 15, delivering the diverted water and fertilizer to each corresponding slow-release supply assembly 2. This is the final delivery pipeline for water and fertilizer. The soil-proof protection box 15 is fitted onto the connection point between the coupling interface 16 and the coupling connector 21, buried in the shallow ground layer. It isolates the coupling interface 16 from soil, roots, and debris, forming an independent, clean connection space. The coupling interface 16 serves as the final connection component of the diversion connection assembly 1, adhering to the coupling connector 21 of the slow-release supply assembly 2 to achieve rapid connection and disconnection between the water and fertilizer delivery pipeline and the buried supply component. It is the connecting node for water and fertilizer delivery. The guide rod 17 provides guidance and positioning for the connection between the coupling interface 16 and the coupling connector 21, ensuring precise alignment during connection and preventing connection failure due to misalignment. In case of water or fertilizer leakage, the upper cover 18 covers the upper surface of the soil protection box 15. The sealing ring on the outer surface of the upper cover 18 seals the upper end of the soil protection box 15, preventing soil, rainwater, and debris from entering the soil protection box 15 and contaminating the docking components. The coupling connector 21, as the top docking component of the slow-release supply assembly 2, adsorbs and docks with the coupling interface 16, realizing the pipeline connection between the diversion docking assembly 1 and the slow-release supply assembly 2. It is the inlet for water and fertilizer to enter the buried shell 23. The guide block 22 can cooperate with the guide rod 17 to provide auxiliary guidance for the docking of the guide block 22 and the coupling interface 16, ensuring that the two fit precisely. To avoid adsorption failure due to misalignment and improve disassembly efficiency, the embedded shell 23 serves as the main structure of the slow-release supply assembly 2. Its embedded design integrates various water and fertilizer storage and slow-release components, protecting internal components from soil compression and corrosion. It acts as a carrier for long-term slow-release water and fertilizer. By installing easily disassembled embedded supply components on the existing device, the installation, maintenance, and replacement of the buried supply device can be conveniently achieved by simply digging up the surface soil without any transfer. Furthermore, individual supply components can be replaced individually to adapt to the planting needs of different tree ages and plots, avoiding the complete abandonment of the entire assembly.
