Combined type agricultural unmanned aerial vehicle

Abstract

The invention discloses a combined type agricultural unmanned aerial vehicle. The combined type agricultural unmanned aerial vehicle structurally comprises spray nozzles, a spray bar, buckles, an aircraft nose, cables, arm levers, paddles, a bearing seat, connecting rods, a medicine box, a medicine box cover, a battery and a landing gear. The four spray nozzles are installed on the spray bar, andthe buckles are fixed to the spray bar in a snap-fit mode. The aircraft nose is horizontally fixed to the top portions of the connecting rods, and the arm levers are welded on both sides of the paddles. The bearing seat is mounted on the aircraft nose, and the landing gear is mechanically connected to the bottom of the aircraft nose. The battery is mounted at the top end of the landing gear. According to the combined type agricultural unmanned aerial vehicle, pin rollers are rotated on guide rails with good stability through check rings, and no offset or shaking occurs; inner rings are drivento rotate by the rolling of the pin rollers, so that the friction between a rotating shaft and the bearing seat is greatly reduced; and the rotation speed of the unmanned aerial vehicle is greatly accelerated, and when the arm levers and the paddles are operated, the friction is reduced and the rotation efficiency is improved to enable the take-off speed of the unmanned aerial vehicle to be higher.

Description

technical field [0001] The invention is a combined agricultural unmanned aerial vehicle, which belongs to the technical field of unmanned aerial vehicles. 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. This type of unmanned aircraft is composed of three parts: flight platform navigation flight control and spraying mechanism. , to achieve spraying operations, you can spray chemicals, seeds, powder and so on. [0003] The prior art discloses a combined pesticide spraying drone with the application number of 201620586100.1, including an unmanned aircraft, a pesticide storage box, a pesticide spraying device, and a power supply device. The unmanned aircraft includes a GPS locator, a flight Speed ​​regulator, master controller, described pesticide reserve tank includes liquid level sensor, liquid inlet, liquid outlet, described ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a combined agricultural drone to solve the problem that the rotating shaft of the agricultural drone in the prior art rotates with the internal bearing seat by sliding. Thus causing greater friction and affecting the speed of rotation
