Description

Technical Field

[0001] This utility model relates to the field of drones, and in particular to a fertilizer spraying box for an agricultural protection drone. Background Technology

[0002] The fertilizer and pesticide spraying tank of an agricultural drone serves as a liquid storage container during the use of the drone. It continuously supplies liquid fertilizer and pesticide solution during the drone's fertilization and spraying process and is used on various agricultural drones.

[0003] However, during operation, as the pesticide solution is continuously consumed, the liquid level in the tank gradually decreases. When the liquid level drops to a low level, especially near the pump inlet, air can easily be drawn in, causing unstable or even interrupted pumping pressure. This not only directly affects the continuity and uniformity of spraying, leading to uneven application and reduced control effectiveness, but may also damage the pump itself. For small-dose applications, a large, fixed-volume tank often cannot be filled completely, leaving numerous internal cavities. During drone flight, especially during turns and climbs, this can cause problems. During descent and other maneuvers, the residual liquid inside the tank shakes violently. This shaking not only generates additional drag and consumes more energy, but more importantly, it causes a significant shift in the drone's center of gravity, severely affecting flight stability and maneuverability, increasing flight risks, and potentially even affecting operational accuracy. Fixed-volume tanks either require frequent returns to refill when demand is high, reducing operational efficiency, or are forced to carry too much liquid when demand is low, exacerbating the shaking problem and causing unnecessary burden and waste. The lack of flexible means to adjust the effective internal volume limits the adaptability of the tank to different operational tasks. Utility Model Content

[0004] The main objective of this invention is to provide a fertilizer and pesticide spraying box for an agricultural drone, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-3 As shown, please refer to the fertilizer and pesticide spraying tank of a crop protection drone. Figures 1-3 The medicine box includes a main body 1, a guide pipe 3, and a sealing cover 5. The guide pipe 3 is fixedly installed on one side of the main body 1, and the sealing cover 5 is fixedly installed on the top of the main body 1. A pipe sealing cap 4 is threaded onto the upper end of the guide pipe 3. A snap-fit ​​strip 7 is embedded in the bottom of the inner wall of the main body 1. A partition structure 8 is provided inside the main body 1 above the snap-fit ​​strip 7. A positioning plate 14 is provided on the outer side of the partition structure 8, and a positioning knob 15 is threaded onto the upper end of the positioning plate 14.

[0020] Please refer to this carefully. Figure 1 and Figure 2 The medicine box body 1 has docking slots 2 on the front and rear sides of its outer side, and the medicine box body 1 is internally connected to the guide pipe 3.

[0021] Please refer to this carefully. Figure 1 and Figure 2 A cover handle 6 is fixedly installed on the upper end of the sealing cover 5, and the sealing cover 5 is embedded in the main body 1 of the medicine box.

[0022] Specifically, the main body 1 of the medicine box is installed on the drone, positioned using the docking slot 2, and connected to the input port of the drone's spray pump via the guide pipe 3.

[0023] Please refer to this carefully. Figure 2 and Figure 3 The partition structure 8 includes a mounting base 9, a telescopic sleeve 10, a tension spring 11, a partition push plate 12, and a sealing rubber ring 13. The mounting base 9 is fixedly installed on the top of the inner wall of the medicine box body 1. The telescopic sleeve 10 is movably installed on one side of the mounting base 9. The tension spring 11 is movably installed inside the telescopic sleeve 10. The partition push plate 12 is fixedly installed at the end of the telescopic sleeve 10 away from the mounting base 9. The sealing rubber ring 13 is sleeved on the outside of the partition push plate 12.

[0024] Please refer to this carefully. Figure 2 and Figure 3The two ends of the tension spring 11 are fixedly connected to the mounting base 9 and the partition push plate 12 respectively, and the partition push plate 12 and the sealing rubber ring 13 are fitted and connected to the inner wall of the medicine box body 1.

[0025] Specifically, the tension spring 11 pulls the partition push plate 12 to move in the direction of the guide tube 3. After liquid is injected into the main body 1 of the medicine tank, the weight of the liquid is greater than the elastic force of the tension spring 11, which pushes the partition push plate 12 to one side. When the liquid in the drone is continuously consumed, the tension spring 11 pulls the partition push plate 12 to move slowly towards the guide tube 3. At the same time, the telescopic sleeve 10 retracts, so that the partition push plate 12 concentrates the liquid and pushes it into the guide tube 3, maintaining the liquid level and stably delivering the liquid to the drone through the guide tube 3.

[0026] Please refer to this carefully. Figure 2 and Figure 3 The positioning plate 14 is fixedly installed on one side of the partition push plate 12. The positioning plate 14 is located above the snap-fit ​​strip 7. The end of the positioning knob 15 passes downward through the positioning plate 14 and is inserted into the hole of the snap-fit ​​strip 7.

[0027] Specifically, when the end of the positioning knob 15 is inserted into the hole of the snap-fit ​​strip 7, the partition push plate 12 is positioned so that the partition push plate 12 cannot be moved. When the partition push plate 12 is positioned at different positions, the size of the space inside the medicine box body 1 is different, thus adjusting the liquid storage space inside the medicine box body 1.
