Plant protection unmanned aerial vehicle with strong stability

Abstract

The invention discloses a plant protection unmanned aerial vehicle with strong stability. The plant protection unmanned aerial vehicle with the strong stability comprises a flight platform, a navigation flight control system and a spraying mechanism; the flight platform comprises a bottom plate, mechanical arms, propellers and tripods, the flight platform is of a symmetrical structure and uses thebottom plate as a center, a plurality of mechanical arms is connected to the edge of the bottom plate by a pipe frame connecting assembly in an evenly transverse mode and can be folded down along theedge of the bottom plate, the propellers are fixedly arranged on the upper end surfaces of the machine arms and driven by a motor which is arranged on the lower portion of the propeller, and the tripods are fixed to the bottom end surface of the bottom plate; the spraying mechanism includes a medicine box, a pump, a transmission liquid pipe and a plurality of nozzles, each of the nozzles is connected to the medicine box through the transmission liquid pipe, the pump is placed in a liquid inlet of the transmission liquid pipe, the medicine box is of an axisymmetric structure, the medicine boxis fixed at the lower end of the bottom plate and is positioned between the tripods, and the nozzles are fixed on the lower end surfaces of the machine arms; and the navigation flight control system is positioned in the bottom plate to control the flight attitude and spray operation of the plant protection unmanned aerial vehicle. According to the plant protection unmanned aerial vehicle with thestrong stability, the operation is convenient, the service life is long, and the stability is enhanced.

Description

technical field [0001] The invention belongs to the technical field of plant protection drones, and in particular relates to a plant protection drone with strong stability. Background technique [0002] Plant protection UAV, also known as unmanned aerial vehicle, as the name implies, is an unmanned aircraft used for agricultural and forestry plant protection operations. Composed of three parts, the spraying operation can be realized through ground remote control or navigation flight control, which can spray chemicals, seeds, powder, etc. Plant protection UAVs are generally rotor UAVs, which provide aircraft lift and aircraft attitude adjustment through forward and reverse rotation and speed control of the propeller. Its battery life is short, the load is moderate, and it has the advantages of being able to hover, especially suitable for hovering It is widely used in the field of agriculture and planting in the workplace. [0003] Since plant protection drones are still in ...

AI Technical Summary

Problems solved by technology

[0004] 1. The pipe frame of the UAV is connected by a horizontal hinge, and the hinge is connected by a hinged spring fastener, which leads to the weight of the UAV and high energy consumption, which affects the battery life of the UAV; the hinged spring fastener also makes the operation inconvenient , easy to get stuck, and after the UAV is used for a long time, the pipe frame connection components are prone to deformation, and the arm droops after deformation, which affects the flight stability of the UAV during flight

[0005] 2. Due to its special operation, the plant protection drone needs to be loaded with a medicine box, which increases the weight of the drone itself and directly leads to poor flight stability.
