Embodiment

[0027] As shown in the accompanying drawings, the left output shaft 311 and the right output shaft 312 respectively extend symmetrically through the gearbox 31 in the center of the fuselage 1 of the present invention's oil-driven horizontal four-rotor agricultural plant protection unmanned helicopter. The left transmission main shaft 33 and the right transmission main shaft 34 are fixedly connected, and are fixed on the side plate brackets on both sides through the pipe frame; There are steering helical gearboxes, which are respectively matched with the rotor transmission mechanisms at their respective positions to complete the horizontal arrangement of the transmission mechanism. Four rotor shafts with equal speeds and opposite directions are realized through the steering gearbox; the four rotor shafts from left to right No. 1 rotor device 41, No. 2 rotor device 42, No. 3 rotor device 43 and No. 4 rotor device 44 are respectively installed on the shaft. Since the directions of...

Abstract

The invention provides an oil-drive transverse type four-rotor agricultural plant protection unmanned helicopter. A rotor mechanism is composed of four rotors. The four rotors are fixedly and transversely arranged on the two sides of a fuselage correspondingly. Every two rotors on the two sides are symmetrical in position and structure along the central axis of the fuselage. The same axial transmission shaft is adopted by the four rotors for constant-speed transmission. The rotating directions of the two rotors on each side are opposite, and the rotating directions of every two rotors in symmetrical positions of the two sides are opposite. The oil-drive transverse type four-rotor agricultural plant protection unmanned helicopter has the beneficial effects that the rotors of the fuselage are arranged in a balanced mode, the transmission speed is stable, the gravity range is wide, the helicopter can fly for work in windy environments, and the flight performance is good; the rotor mechanism is transversely arranged, the rotating speeds in symmetrical positions of the rotor mechanism are the same, the rotating directions in symmetrical positions of the rotor mechanism are opposite, and thus counter torsion generated by high-speed rotation of the rotors is eliminated reasonably; and through the transverse overlapping arrangement way, vortex disturbance of blade tips of the rotors of the helicopter is eliminated, the influence on pesticide spraying of a spray lance is eliminated, and sprayed pesticides can fully act on plants through downward airflow, the pesticide application effect is improved, and the pesticide utilization rate is increased.

Description

technical field [0001] The invention relates to an aerial vehicle specially for pesticide spraying and fertilization in the field of crop protection. Background technique [0002] At present, domestic plant protection drones are still in the exploratory stage, and most of them are multi-axis and multi-rotor electric. Multi-axis and multi-rotor plant protection drones have the advantages of stable flight and easy control. The structural features show many insurmountable defects, such as: 1. A single rotor rotates at high speed to form a downwash airflow, and at the same time, a vertical upward vortex is formed at the tip of the blade, so that the sprayed liquid medicine is swept into the air by the vortex , multi-axis and multi-rotor drones are especially obvious; 2. Multi-axis and multi-rotor rotors rotate in opposite directions, and the rotors are concentrated in the middle of the spray bar, forming turbulent flows up and down, left and right, and the liquid sprayed at both...
