Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and specifically relates to an agricultural spraying UAV. Background Technology

[0002] Agricultural spraying drones, also known as plant protection drones, are unmanned aircraft used for the protection of agricultural and forestry plants. Traditional manual spraying relies on backpack equipment, which is inefficient, costly, and carries the risk of pesticide exposure. Ground machinery is limited by terrain and cannot achieve large-scale operations, resulting in low pesticide utilization and serious waste. Drone spraying technology can improve pesticide utilization, reduce pesticide residues, and reduce environmental pollution.

[0003] In current agricultural plant protection operations, during the pesticide application process, operators need to manually pour pesticide solution directly into the drone's built-in tank while the drone is stationary. This significantly reduces the overall efficiency of the operation and further prolongs the time required for each pesticide application. Utility Model Content

[0004] To address the problem that manual pouring of pesticides from a tank on a drone is required for pesticide application, which significantly reduces overall operational efficiency, this invention proposes an agricultural spraying drone to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an agricultural spraying drone, comprising a body, a limiting component at the bottom of the body, a liquid storage component inside the limiting component, a spraying component on the outer surface of the liquid storage component, and a telescopic component between the spraying component and the liquid storage component. The limiting component is used to fix the liquid storage component, the liquid storage component is used to store the pesticide solution, the spraying component is used to guide the spraying of the pesticide solution, and the telescopic component is used to connect and replace the liquid storage component.

[0007] Furthermore, the limiting component includes a frame, which is fixedly installed at the bottom of the machine body. A door frame is rotatably connected to one side of the frame. A locking post is fixedly installed inside the door frame and inside the other side of the frame. A support post is fixedly connected inside the frame.

[0008] Furthermore, the liquid storage assembly includes a medicine tank, which is placed on the top of the support column. A handle is fixedly connected to one end of the medicine tank, and a lid is threadedly connected to one end of the medicine tank. A water outlet pipe is fixedly connected to the outer surface of the medicine tank, and the medicine tank and the water outlet pipe are interconnected.

[0009] Furthermore, the telescopic assembly includes a quick-change head, one end of which is inserted into a water outlet pipe, and the other end of which is slidably connected to a connector. A spring is installed between the quick-change head and the connector, and a fixing block is threadedly connected to one end of the connector. The water outlet pipe, quick-change head, connector, and fixing block are interconnected.

[0010] Furthermore, the spraying assembly includes a water inlet pipe, a fixing block is fixedly installed at one end of the water inlet pipe, a water pump is fixedly installed at the other end of the water inlet pipe, a spraying pipe is fixedly installed on the outer surface of the water pump, and a nozzle is fixedly connected to the outer surface of the spraying pipe.
