[0002] Agricultural drone pesticide spraying devices are highly integrated systems. Through the application of automation and intelligent technologies, they greatly improve the efficiency, accuracy, and safety of pesticide application while reducing environmental impact.

[0003] First, if this device does not have a quick installation function, the operator will need to spend more time on complex installation and adjustment, which will prolong the preparation time for each operation and thus affect the overall work efficiency.

[0004] Secondly, if the spraying components installed at the bottom of the water tank are not secured, the bottom of the water tank may become loose due to vibration or external forces changing during flight. This may lead to unstable supply of pesticide solution, uneven spraying, or even pesticide leakage.

[0005] Finally, if the water tank is poorly designed, the pesticide may not be completely drained from the tank, resulting in pesticide residue after each operation. This not only wastes pesticides but also increases the difficulty of cleaning the equipment. Summary of the Invention

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please see Figures 1-5A pesticide spraying device for agricultural drones includes a water tank 1, an installation mechanism, a positioning mechanism, and an operating mechanism. The installation mechanism includes an installation plate 2 and a drive component 3. The installation plate 2 is installed on and connected to the water tank 1. The drive component 3 is installed on and slidably connected to the installation plate 2. A connecting rod 4 is installed at one end of the installation plate 2, and a clamping block 5 is installed at the other end of the connecting rod 4. The connecting rod 4 is rotatably connected to the installation plate 2 and the clamping block 5, respectively. The clamping block 5 is slidably connected to the installation plate 2. The positioning mechanism includes a connecting screw 6 and a positioning plate 7. The positioning plate 7 is rotatably connected to the connecting screw 6 and connected to the installation plate 2, respectively. The connecting screw 6 is connected to the water tank 1. A limit frame 8 is installed on the installation plate 2, and the limit frame 8 is connected to the installation plate 2.

[0022] In this embodiment, the installation mechanism includes an installation plate 2 and a driving component 3. In use, the installation plate 2 can be installed at the bottom of the water tank 1. The installation plate 2 is then connected to the external rod 16 at the bottom of the water tank 1. When installing the installation plate 2, the driving component 3 can be pressed directly, causing the driving component 3 to compress the spring 15 and slide within the installation plate 2. The sliding of the driving component 3 causes a change in the position of the connecting rod 4, allowing the clamping block 5, which is rotatably connected to one end of the connecting rod 4, to retract directly into the installation plate 2. When the installation plate 2 is in close contact with the bottom of the water tank 1, the driving component 3 is released, allowing the spring 15 to directly push the driving component 3. This pushes the clamping block 5 into the locking hole 17 on the external rod 16, thus directly connecting the installation plate 2 and the external rod 16. When the installation plate 2 is installed at the bottom of the water tank 1, the battery pack 9 is also connected to the water tank 1.

[0023] In this embodiment, the positioning mechanism includes a connecting screw 6 and a positioning plate 7. In use, the connecting screw 6 can be installed into the threaded hole 18 of the external rod 16. When the connecting screw 6 rotates, the positioning plate 7 can directly engage with the positioning hole 19 on the driving component 3, fixing the position of the driving component 3 and ensuring the fixed connection between the mounting plate 2 and the water tank 1. The connecting bracket 10 can be installed into the mounting plate 2. When the connecting bracket 10 enters the mounting plate 2, the limiting bracket 8 can be installed onto the mounting plate 2. The limiting groove 21 on the limiting bracket 8 is slidably connected to the limiting block 20 on the connecting bracket 10, allowing the connecting bracket 10 to be easily disassembled from the mounting plate 2. The limiting bracket 8 is fixedly connected to the mounting plate 2 by bolts.

[0024] In this embodiment, the operating mechanism includes a battery pack 9 and a connecting frame 10. After the mounting plate 2 and the connecting frame 10 are installed, the hose 13 can be directly connected to the water pump 11 in the connecting frame 10. Then, the water tank 1 can be connected to the drone through the connecting plate 14. In addition, pesticide is introduced into the inlet 22 on one side of the water tank 1. After that, the water pump 11 installed in the connecting frame 10 draws the pesticide from the water tank 1 through the hose 13. Under the action of the flow block 23, the pesticide in the water tank 1 will not be excessively retained, and it can be sprayed out through the spraying part 12 of the water pump 11. With the cooperation of the drone, the pesticide spraying is completed.

[0025] Example 2: In summary, during use, the mounting plate 2 can be installed onto the bottom of the water tank 1. The mounting plate 2 then connects with the external rod 16 at the bottom of the water tank 1. While installing the mounting plate 2, the driving component 3 can be pressed down, causing it to compress the spring 15 and slide within the mounting plate 2. This sliding motion of the driving component 3 changes the position of the connecting rod 4, allowing the clamping block 5, which is rotatably connected to one end of the connecting rod 4, to retract directly into the mounting plate 2. When the mounting plate 2 is in tight contact with the bottom of the water tank 1, it can then be released. The driving component 3 allows the spring 15 to directly push the driving component 3, thereby pushing the clamping block 5 into the locking hole 17 on the external rod 16. This allows the mounting plate 2 to be directly connected to the external rod 16. When the mounting plate 2 is installed at the bottom of the water tank 1, the battery pack 9 also connects to the water tank 1. Furthermore, to ensure a stable connection between the mounting plate 2 and the water tank 1, the connecting screw 6 can be installed into the threaded hole 18 of the external rod 16. When the connecting screw 6 rotates, the positioning plate 7 can directly engage with the driving component 3. The positioning hole 19 on the upper part is engaged to fix the position of the driving component 3, thereby ensuring the fixed connection between the mounting plate 2 and the water tank 1, and the connecting bracket 10 can be installed into the mounting plate 2. When the connecting bracket 10 enters the mounting plate 2, the limiting bracket 8 can be installed on the mounting plate 2. At this time, the limiting groove 21 on the limiting bracket 8 is slidably connected with the limiting block 20 on the connecting bracket 10, so that the connecting bracket 10 can be easily disassembled from the mounting plate 2. Moreover, the limiting bracket 8 is fixedly connected to the mounting plate 2 by bolts. When all components are installed... Afterwards, the hose 13 can be directly connected to the water pump 11 in the connecting frame 10. Then, the water tank 1 can be connected to the drone through the connecting plate 14. In addition, the pesticide is introduced into the inlet 22 on one side of the water tank 1. After that, the water pump 11 installed in the connecting frame 10 draws the pesticide from the water tank 1 through the hose 13. Under the action of the flow block 23, the pesticide in the water tank 1 will not be excessively retained, and it can be sprayed out through the spraying part 12 of the water pump 11. With the cooperation of the drone, the pesticide spraying is completed.

[0026] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
