[0018] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] like Figure 1-4As shown, a soil conditioner release device mounted on a drone includes a cover plate 1, a storage tank 6, an atomizing nozzle 12, a diaphragm pump 14, a control component 15, and a power supply component 16. The cover plate has hinged arms 2 on both sides of its upper end. The ends of the arms 2 are hook structures 3, which can hook onto the supports on both sides of the drone's bottom, forming a stable trapezoidal structure under gravity, providing favorable conditions for the device's operation. The cover plate 1 is detachably connected to the upper end of the storage tank 6. The storage tank 6 has an upward-opening storage trough 601 in the middle for storing liquid soil conditioner. The cover plate 1 and the storage trough 601 form a sealed storage space to prevent leakage. The upper end of the cover plate 1 has a vent valve 5 that connects to the storage space; a one-way valve can also be used to provide pressure balance within the storage space. The atomizing nozzle 12 has multiple... Each component is installed at the bottom of the storage tank 6. The diaphragm pump 14, control component 15, and power supply component 16 are all installed on the side of the storage tank 6. The inlet of the diaphragm pump 14 is located at the bottom of the storage tank 601, continuously drawing liquid soil conditioner. The outlet of the diaphragm pump 14 is connected to the atomizing nozzle 12, continuously atomizing and spraying the liquid soil conditioner. A sinking space 602 is provided at the location where the diaphragm pump 14 draws liquid, so that when the liquid in the storage tank 601 is about to run out, it can be concentrated in the sinking space 602, improving the liquid utilization rate of each spraying operation. The control component 15 is signal-connected to the diaphragm pump 14 and can be connected to a backend such as a mobile app, allowing manual control of the start and stop status of the diaphragm pump 14. The power supply component 16 is electrically connected to the control component 15 and the diaphragm pump 14, providing them with power. Both the cover plate 1 and the liquid storage tank 6 of this device can be manufactured using 3D printing. The 3D printing material selected is glass fiber reinforced nylon 12, which has good resistance to weak acids and alkalis with pH 4-10, good oil resistance, and strong tolerance to most water-based conditioners such as foliar fertilizers and growth inhibitors. Although it is not resistant to strong acids, alkalis, and strong solvents, it is sufficient for the use and storage of most liquid soil conditioners. This material is commonly printed using selective laser sintering, resulting in high-density prints with few voids and minimal leakage. The material cost is approximately 300 RMB / kg, making it most suitable for this technical solution and related conventional agricultural scenarios. The device is conveniently and quickly mounted on a drone's bracket. By controlling the drone to fly to the designated area and simultaneously operating the diaphragm pump 14, the liquid soil conditioner is sprayed onto the farmland through the atomizing nozzle 12. The drone's flight enables rapid spraying of the soil conditioner, improving spraying efficiency and uniformity, saving significant labor costs, and increasing work efficiency.

[0020] The opening of the hook structure 3 is angled downwards and outwards. After the hook structure 3 leans against and moves upwards past the drone support, it moves downwards to automatically engage with the drone support and hold it in place. With both hook structures 3 holding the drone support together, automatic locking is achieved under gravity, which is convenient and quick. A locking screw 4 is provided on the outer side of the hook structure 3, extending to the inner side. After the hook structure 3 engages with the drone support, the locking screw 4 can lock the drone support, preventing it from detaching from the hook structure 3 and ensuring the drone's flight and landing safety. The upper end of the cover plate 1 has a through slot 101, and the upper end of the liquid storage tank 6 has a buckle 7. The buckle 7 can be inserted into the slot 101, enabling quick assembly and disassembly of the liquid storage tank 6, facilitating tasks such as drone battery replacement and liquid replenishment in the liquid storage tank 601. The upper end of the buckle 7 is a triangular structure, and the lower end face of the triangular structure can be placed on the upper end face of the slot 101. At the same time, the upper end face of the liquid storage tank 6 abuts against the lower end face of the cover plate 1, realizing a tight connection between the cover plate 1 and the liquid storage tank 6. A sealing ring 8 is provided on the upper end face of the liquid storage tank 6 around the liquid storage tank 601 to ensure that when the cover plate 1 and the liquid storage tank 6 are combined, the liquid in the liquid storage tank 601 will not overflow through the gap between the cover plate 1 and the liquid storage tank 6. To separate the cover plate 1 and the liquid storage tank 6, simply push the triangular structure back into the slot 101, and the cover plate 1 can be pulled up or the liquid storage tank 6 can be pulled down. This is also due to the deformation capability of the 3D printing material. At the same time, in the structural design, the thickness needs to be considered at the connection between the triangular structure and the liquid storage tank 6 to ensure that the triangular structure has sufficient deformation space. The liquid storage tank 6 has a replenishment port 603 on its side that connects to the top of the liquid storage tank 601. Liquid soil conditioner can be replenished without removing the liquid storage tank 6. The replenishment port 603 is threaded with a cap 9 to prevent liquid leakage.

[0021] In addition, this technical solution also includes a solenoid valve 13, a liquid level column 10, and a buffer bracket 11; the solenoid valve 13 is connected between the diaphragm pump 14 and the atomizing nozzle 12, which can accurately control the flow of the liquid, protect the diaphragm pump 14 from damage caused by backflow of liquid, and quickly cut off the liquid when there is no need to spray liquid soil conditioner, reducing residue waste; the liquid level column 10 is installed on the side of the storage tank 6, and the liquid level column 10 is connected to the bottom of the storage tank 601, so that when the liquid soil conditioner is replenished through the replenishment port 603... The liquid level in the storage tank 601 can be observed and controlled without removing the storage tank 6. The buffer bracket 11 is installed on both sides of the storage tank 6, with the bottom of the buffer bracket 11 located below the storage tank 6 and the atomizing nozzle 12, providing a strong stopping condition for the device and effectively protecting the atomizing nozzle 12 from bumps and impacts. The buffer bracket 11 has a hollow structure, which is lightweight and has better deformation capacity. It can provide a certain buffer for the device when the drone lands, making the drone land more smoothly.

[0022] Before operation, liquid soil conditioner is injected into the storage tank 601 until it reaches 80-90% capacity. Then, the cover plate 1 is installed, and the buckle 7 is inserted into the slot 101, with the lower end of the buckle 7 hanging on the upper end of the storage tank 6. At this point, the cover plate 1 and the storage tank 6 are tightly connected, forming a sealed storage space through the sealing ring 8. The two hanging arms 2 on the cover plate 1 are leaned against the drone support, and the drone is lifted upwards so that its support is embedded in the hook structure 3. The connection is secured with the locking screws 4, and spraying can then begin. The drone is controlled to fly over the farmland, and the diaphragm pump 14 is started and the solenoid valve 13 is opened via a mobile app. This draws liquid soil conditioner from the storage tank 601 into the atomizing nozzle 12 for spraying. During spraying, the drone simultaneously circles the farmland to ensure even spraying. After spraying in each area, the drone returns to the starting point, where staff check the drone's battery level and the liquid level in the storage tank 6. Appropriate charging and replenishment are performed before the next operation. This device enables rapid assembly and disassembly of the cover plate 1 and the liquid storage tank 6, as well as rapid assembly and disassembly with the drone. By using the drone to fly, the soil conditioner can be sprayed quickly, improving the spraying efficiency and uniformity of the soil conditioner, saving a lot of labor costs, and improving work efficiency.
