[0002] An agricultural drone refers to a drone system specifically designed for the agricultural field. They utilize advanced aviation technologies and sensor devices to perform various agricultural tasks in an autonomous or remotely controlled manner. Some agricultural drones can automatically perform seeding and spraying tasks, accurately dispensing seeds, fertilizers, or pesticides, reducing resource waste and environmental pollution, and improving crop yield and quality.

[0003] When a drone is performing a spraying task, a spraying frame is installed below it, and pesticides and fertilizers are sprayed downward onto the crops along with the flight of the drone through multiple nozzles. However, the overall spraying range formed by the multiple nozzles in the spraying frame is limited. When spraying different types of crops, the overall spraying effect of pesticides and fertilizers may be affected due to an overly large or small spraying range, thereby having a certain impact on the overall usage efficiency of the agricultural drone.

[0004] Regarding the above related technologies, the inventor believes that there is a defect in the spraying frame of the agricultural drone that it is not convenient to adjust the spraying range during use. Therefore, a spraying frame for an agricultural drone is proposed to solve the above problems. Utility Model Content

A spacing adjustment mechanism is further provided on the outer surface of the storage tank for adjusting the movement of the movable pipe along the inside of the fixed pipe.

[0008] Preferably, the spacing adjustment mechanism includes a fixed frame symmetrically welded at the bottom end of the storage tank. Both sides of the inner wall of a single fixed frame pass through the fixing member and are rotatably installed with a bidirectional lead screw. Both sides of the inner wall of the other fixed frame pass through the fixing member and are fixedly connected with a guiding support rod.

[0009] Preferably, one side of the top of the movable pipe is placed inside the fixed pipe and welded with a sealing gasket, and the outer surface of the sealing gasket is closely attached to the inner wall of the fixed pipe.

[0010] Preferably, the cross-section of the movable pipe is a U-shaped structure, the outer diameter of the movable pipe is smaller than the inner diameter of the fixed pipe, and the fixed pipe and the movable pipe are mutually fitted.
