Description

Technical Field

[0001] This utility model relates to the field of agricultural drone technology, specifically an agricultural drone for spraying. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently. In agricultural planting, pesticides need to be sprayed on crops. Manual spraying is inefficient, so UAVs are often used to spray pesticides to improve efficiency.

[0003] When using existing spraying agricultural drones, traditional spraying agricultural drones often have multiple nozzles on the drone, but the angle of the nozzles is fixed and cannot be adjusted according to actual needs.

[0004] Therefore, an agricultural drone for spraying was designed based on the above-mentioned technical problems. Utility Model Content

[0005] To address the problem that the angle of the nozzles on existing agricultural spraying drones is fixed and cannot be adjusted according to actual needs, this utility model proposes an agricultural spraying drone.

[0006] The technical solution adopted by this utility model to solve its technical problem is an agricultural drone for spraying, including a drone body, on which a spraying frame assembly is suspended. The spraying frame assembly includes a suspension frame and a spraying pipe mounted on the suspension frame. The spraying pipe is provided with multiple nozzles. The suspension frame includes a bracket and a hanger. The bracket and the hanger are hinged together. The hanger can rotate around the bracket. A rotating disk is connected at the hinge. The hanger and the spraying pipe are detachably connected.

[0007] Working principle: There are generally two types of spraying drones in the existing technology. One type uses a canister to be added directly to the drone to achieve spraying. However, this often results in a short working time due to weight issues. Therefore, the existing technology involves connecting a pipe to the drone for spraying. However, when spraying multiple crops, it is impossible to adjust the spraying angle according to the angle of the crops. Therefore, this application solves the problem by setting up a suspension frame. The spray pipe is placed on the suspension frame and connected to the suspension frame by a hinge. This allows the spray pipe to rotate relative to the suspension frame, thereby changing the angle of the nozzles on the spray pipe.

[0008] Preferably, the drone body has multiple legs at its bottom, and the legs are evenly spaced around the spray frame assembly, which makes landing more stable and protects the safety of the spray frame assembly.

[0009] Preferably, the bracket is a frame structure, the hanging bracket includes two uprights, the two uprights are arranged in parallel, the two uprights are respectively hinged to the frame of the bracket, the rotating disk is connected to a servo motor, the servo motor drives the uprights to rotate along the bracket, and the spray pipe is arranged on the two uprights.

[0010] Preferably, both of the uprights are provided with mounting slots, and the spray pipe is inserted into the mounting slots for easy and quick installation of the spray pipe.

[0011] Preferably, the drone body includes a fuselage and a propeller assembly mounted on the fuselage. The propeller assembly includes multiple flight frames, with a propeller located on the outermost side of each flight frame.

[0012] Preferably, the flight frame is detachably connected to the fuselage, and there are eight flight frames, which makes the flight more stable.

[0013] Preferably, a protective shell is provided at the upper end of the connection between the flight frame and the fuselage. The protective shell is a two-layer disc structure, and the brackets are evenly distributed and inserted in the middle of the protective shell, making the bracket structure more stable.

[0014] Preferably, the frame structure of the bracket includes multiple side strips, which are detachably connected to facilitate the installation and disassembly of the bracket.

[0015] The advantages of this utility model are:

[0016] This invention uses a hinged connection between the suspension frame and the spray pipe, allowing the spray pipe to rotate relative to the suspension frame, thereby changing the spray angle and facilitating adjustment according to the desired spray angle.

[0017] 2. The drone body of this utility model is provided with multiple support legs at the bottom. The support legs are located around the spray frame assembly, which makes the landing more stable and protects the safety of the spray frame assembly.

[0018] 3. Both of the two uprights of this utility model are provided with mounting grooves, and the spray pipe is inserted into the mounting grooves for convenient and quick installation of the spray pipe.

[0026] Please see Figures 1 to 3 As shown, an agricultural drone for spraying includes a drone body 1, on which a spraying frame assembly 2 is suspended. The spraying frame assembly 2 includes a suspension frame 201 and a spray pipe 3 mounted on the suspension frame 201. The spray pipe 3 is provided with multiple nozzles 4. The suspension frame 201 includes a bracket 202 and a hanging frame 203. The bracket 202 and the hanging frame 203 are hinged together. The hanging frame 203 can rotate around the bracket 202. A rotating disk 204 is connected to the hinge. The hanging frame 203 is detachably connected to the spray pipe 3.

[0027] In another embodiment, the bottom of the drone body 1 is provided with multiple legs 5, and the legs 5 are evenly spaced around the spray frame assembly 2. The legs 5 are arranged in a triangle around the spray frame assembly 2, which ensures the stability of landing while reducing its own weight. At the same time, because they are arranged around the spray frame assembly, the landing is more stable and the safety of the spray frame assembly 2 is protected.

[0028] In another embodiment, the support 202 is a frame structure, the hanger 203 includes two uprights 205, which are arranged in parallel and are respectively hinged to the frame of the support 202.
