Plant protection unmanned flight device

Abstract

The invention discloses a plant protection unmanned flight device which comprises a rack, rotor wings, a remote control assembly, a liquid pump and a container barrel. The container barrel is fixed tothe middle of the rack and comprises an inlet, a channel, a containing cavity, partition plates and an outlet, the outlet is connected to the liquid pump, the containing cavity is divided into a plurality of alternate partition cavities through the multiple partition plates, and a driving device is arranged at the top of each partition plate; and a gate and a flashboard are arranged at the bottomof each partition plate, each gate communicates with the adjacent first partition cavity and second partition cavity, the driving devices are connected to the remote control assembly and the flashboards, and the flashboards are lifted up and down to open and close the gates. The partition plates and the gates are additionally arranged in the unmanned flight device to divide liquid into a plurality of areas, so that when the unmanned flight device accelerates and decelerates, the partition plates can prevent the liquid in the container barrel from moving excessively, and the gravity center ofthe liquid is basically kept in the center of the container barrel; and the gates control flow of the liquid, so that solutions can be effectively separated in the test flight stage, mixing of the solutions is avoided, and the pesticide effect is ensured to be in a high-quality state during spraying.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial device for plant protection. Background technique [0002] The plant protection unmanned aerial device is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flying platform (fixed wing, helicopter, multi-axis aircraft), navigation flight control, and spraying mechanism. Or navigate the flight control to realize the spraying operation, which can spray chemicals, seeds, powders, etc. At present, plant protection drones are mainly used for spraying pesticides. [0003] There are a large number of mixtures of pesticides, fungicides and fungicides or other types of pesticides are mixed and used immediately, which can expand the scope of control, delay drug resistance, enhance the effect, reduce the cost of drug use, and save labor and time. Generally, protective fung...

AI Technical Summary

Problems solved by technology

[0005] 1. The drone needs to be calibrated many times before flying, especially it needs to be pre-flyed close to the ground to ensure that its center of gravity does not shift. Therefore, after the pesticide is mixed in the container bucket, it takes more time and time to test the flight stage, resulting in the pesticide efficacy reduce

[0006] 2. Since most of the medicinal liquid in the container barrel is liquid, when the UAV turns, turns, and moves in the opposite direction, the liquid impacts the inner wall of the container barrel with inertia, and when accelerating or decelerating, the liquid impacts the inner wall of the container barrel to form a large wave, resulting in The drone's center of gravity shifts greatly and the position of the center of gravity is constantly changing, which can easily cause the drone's center of gravity to be unstable and cause it to fly obliquely or even risk falling. After the center of gravity is completely shifted to the front, the drone leans forward, and at the same time, the waves formed by the liquid surge in the barrel, causing the drone to still shake when it leans forward
