Detailed Implementation

[0021] 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.

[0022] The following is combined Figures 1-6 This invention provides a detailed description of a drone used for spraying pesticides:

[0023] A pesticide spraying drone includes a fuselage 1, arms 2, and landing gear 3. The arms 2 are arranged in four sets, symmetrically at both ends of the fuselage 1. The landing gear 3 is installed at the lower end of the fuselage 1. A control module is installed inside the fuselage 1, and the arms 2 are controlled by the control module. A pesticide tank placement slot 4 is provided in the middle of the fuselage 1. A detachable pesticide tank 5 is installed in the pesticide tank placement slot 4. An electronically controlled nozzle 6 is provided at the lower end of the pesticide tank 5. The electronically controlled nozzle 6 is electrically connected to the fuselage 1 through a control line 601 and is connected to the pesticide tank 5. The electronically controlled nozzle 6 is combined with the pesticide tank 5 through a quick-release structure.

[0024] The quick-release structure includes a quick-release base 7 located at the bottom of the medicine box 5 and a quick-release ring 8 near one end of the electronically controlled nozzle 6 near the medicine box 5. The quick-release base 7 is threadedly connected to the liquid outlet of the medicine box 5. The surface of the quick-release base 7 is provided with a positioning groove 701 and a locking buckle 9. The edge of the quick-release ring 8 is provided with a positioning insert 801 and a locking opening 802. After the locking buckle 9 is rotated, it can push the positioning insert 801 to be paired and inserted into the positioning groove 701, and press the locking opening 802, so that the opposite side of the quick-release ring 8 and the quick-release base 7 are in contact.

[0025] The quick-release structure enables rapid replacement and reliable connection of the electronically controlled nozzle 6. When installing the nozzle 6, simply align the quick-release ring 8 of the nozzle 6 with the quick-release base 7 at the bottom of the medicine box 5, and then rotate the locking lever 9. During this process, the locking lever 9 pushes the quick-release ring 8 to move horizontally, allowing the positioning block 801 at one end to precisely align and insert into the positioning slot 701 on the quick-release base 7. Simultaneously, the locking opening 802 on the other side of the quick-release ring 8 is firmly pressed shut by the rotated locking lever 9. This series of actions ultimately ensures a tight fit between the quick-release ring 8 and the quick-release base 7, achieving a stable mechanical connection and smooth liquid flow between the electronically controlled nozzle 6 and the medicine box 5. Installation and removal can be completed without any tools, greatly simplifying the operation and saving time, allowing for rapid replacement of different types of electronically controlled nozzles 6 on-site as needed.

[0026] The quick-connect ring 8 and quick-connect base 7 are equipped with magnetic blocks 10 that can be paired and attracted to each other. The magnetic blocks 10 are embedded in the quick-connect ring 8 and quick-connect base 7, generating a pre-positioning magnetic force at the initial stage of connection. Before final locking, the two components can automatically and initially align and maintain an attracted state, simplifying the manual alignment steps during installation, making the connection process smoother and faster, and improving assembly efficiency, especially in environments where operation is inconvenient. After the electronically controlled nozzle 6 is installed, the positions of the two magnetic blocks 10 are staggered. The quick-release ring 8 has a sealing gasket 11 on the side near the control seat, and the quick-release seat 7 has a sealing groove on the side near the quick-release ring 8. When the quick-release ring 8 and the quick-release seat 7 are combined, the sealing gasket 11 is located in the sealing groove and is tightly attached to the inner wall of the sealing groove. This significantly enhances the sealing performance at the connection between the electronically controlled nozzle 6 and the pesticide tank 5, completely preventing pesticide leakage or volatilization at the connection point. This ensures spraying efficiency, avoids pesticide corrosion of drone parts and environmental pollution, and improves operational safety.

[0027] The locking lever 9 is circular, and its edge has an unlocking groove 901. The locking lever is rotatably connected to the quick-release base 7 via a coaxially mounted pivot. When the unlocking groove 901 is rotated to align with the electronically controlled nozzle 6, the locking lever separates from the quick-release ring 8. Under the action of the two magnetic blocks 10, the quick-release ring 8 moves within the quick-release base 7, causing the positioning insert 801 to be pulled out of the positioning slot 701. At this point, the electronically controlled nozzle 6 and the quick-release ring 8 can be directly removed. The surface of the locking lever is provided with a raised grip plate 902, which directly increases the contact area and friction between the hand and the operating component. This makes the hand feel more comfortable and the force more direct when rotating the locking lever 9 by hand, effectively preventing slippage during operation and further improving the convenience and efficiency of operation.

[0028] The fuselage 1 has a power supply slot 12 and a battery 13 located in its middle. The battery 13 is placed in the power supply slot 12 and supplies power to the fuselage 1, the arm 2, the control module, and the electronically controlled nozzle 6. The modular power supply installation method makes it easier to replace, maintain, and charge the battery 13, providing a stable and reliable energy guarantee for the drone and ensuring the endurance of spraying operations.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
