A double-rotor coaxial safety anti-collision electric unmanned plant protection machine

Abstract

The invention provides a dual-rotor-wing coaxial safe anti-collision power-driven unmanned plant protection machine which comprises a machine body and a spherical protective screen, wherein the machine body is positioned in the protective screen, and a rigid protective screen circular ring is arranged in the spherical protective screen; a support of the machine body is a universal platform circular ring, on which a main supporting rod is arranged in a diameter direction; the universal platform circular ring is embedded in the protective screen circular ring; the outer wall of the universal platform circular ring is tightly adhered with the inner wall of the outer ring, and can slide at any angles. Due to arrangement of the universal platform and the protective screen, the plant protection machine provided by the invention has the advantages of being high in flying stability, safety coefficient, collision resistance and environmental suitability.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a double-rotor coaxial safety anti-collision electric unmanned plant protection machine. Background technique [0002] At present, most of the general-purpose plant protection aircraft on the market are single-rotor and multi-rotor, and most of them are driven by fuel engines. The structure of the single-rotor plant protection aircraft is similar to that of a helicopter. When the rotor rotates at a high speed, the rotational torque generated will cause the plant protection aircraft to rotate in situ, so the tail needs to be added. The torque generated by the rotating tail is used to balance the rotational torque generated by the high-speed rotation of the main rotor to form a dynamic balance to control the attitude of the helicopter. The multi-rotor plant protection aircraft is composed of several small rotors scattered on the top of the plant protection aircraft, and the r...

AI Technical Summary

Problems solved by technology

The multi-rotor plant protection aircraft is easy to control and stable in flight, but it is bulky and complex in structure, and has strict requirements on the take-off site

[0003] The plant protection machine driven by fuel power has high energy consumption and large exhaust emissions, which does not meet the national requirements for energy-saving and emission reduction products; when the plant protection machine is working, when the high-speed rotating rotor touches people and livestock, it will cause serious injury; When hitting obstacles such as trees and wires, the rotor is easy to break, resulting in a crash
