Compact long-endurance plant protection unmanned aerial vehicle

Abstract

The invention provides a compact long-endurance plant protection unmanned aerial vehicle, which comprises a fuselage, wherein the fuselage comprises a first support plate, and an oil tank and a medicine box supported by the first support plate are arranged on the upper part; The middle part is provided with a second support plate and four rotor assemblies, and the second support plate is providedwith a plurality of control modules; A low part is provided with a shock absorb assembly, a driving assembly, a shower device and a fuselage leg; The first support plate and the second support plate are fixedly connected, an overhead layer is formed between the first support plate and the second support plate, and the control module is arranged in the overhead layer; The plurality of rotor assemblies are arranged on the side of the overhead layer and are articulated with the first support plate. An upper end of that shock absorb assembly is connected with a bottom surface of the second supportplate, and a lower end is connected with a driving assembly; The drive assembly comprises an engine assembly and a generator set component, wherein the engine assembly supplies oil through a fuel tank to drive the generator set component to generate electricity, thereby realizing the energy supply of the unmanned aerial vehicle; The spray device comprises two spray rods, wherein the spray rods are vertically fixedly connected with a rotor assembly, and a spray head is arranged at a lower end.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a long-endurance plant protection unmanned aerial vehicle with a compact structure. Background technique [0002] Plant protection UAV, as the name suggests, 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. Remote control or navigation flight control to realize spraying operations, which can spray chemicals, seeds, powders, etc. [0003] Plant protection UAVs are also gradually expanding their scope of use, and their application range is becoming wider and wider. It has the following advantages: (1) Simple operation: the multi-rotor agricultural plant protection machine can be raised and landed on the ridge of the field, from a few meters low Flying can c...
