A multi-rotor UAV with a centrifugal nozzle

Abstract

The invention relates to the technical field of agricultural drones, and provides a multi-rotor drone with a centrifugal nozzle, including a fuselage with a container and a plurality of hollow wing arms connected to the fuselage, each of the wing arms A drive seat is provided on the drive seat, and a propeller is provided on the drive seat; a spray head is also provided on the wing arm, and the spray head includes a shroud, an impeller and a motor, the motor is fixed in the shroud, and the motor A drive shaft is provided, and the drive shaft extends from the motor to the outside of the wind deflector; the impeller is arranged outside the mouth of the wind deflector and is connected with the drive shaft of the motor; the wing arm An infusion tube is arranged inside, and one end of the infusion tube is connected with the container on the fuselage, and the other end is connected with the shroud. The invention improves the structure of the spray head of the unmanned aerial vehicle. While effectively atomizing the spray liquid, it can also increase the intensity of the spray liquid, so that the sprayed liquid material can penetrate the interior of the crops, and effectively improve the spraying effect. .

Description

technical field [0001] The invention relates to the technical field of agricultural drones, in particular to a multi-rotor drone with a centrifugal nozzle. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. With the rapid development of science and technology, drone technology is becoming more and more mature, and the application of drones has gradually entered the public eye, and the application of drones in civilian applications is becoming more and more extensive, especially in planting. UAVs can effectively replace manual operations by spraying pesticides or fertilizing crops, saving operating time and labor costs, and improving production efficiency. [0003] At present, agricultural drones on the market are generally divided into two types, including drones with fixed wings and drones with multi-rotors. For fixed-wing unmanned aerial vehicles, since a certain distance and spa...

AI Technical Summary

Problems solved by technology

But for multi-rotor drones, since the motor of the propeller is mainly used to provide power for the propeller, and the impeller in the nozzle is only used as a linkage to provide power output, although under the rotation of the impeller, the spray liquid can be dispersed. To achieve the atomization effect, but it is difficult to provide enough power to output the spray liquid, resulting in weak spray liquid intensity, unable to penetrate the interior of the crops, and difficult to meet the spraying requirements

[0006] Therefore, the UAVs of the prior art cannot meet the requirements of hovering spraying and spraying intensity at the same time, which is a research problem for current agricultural UAV manufacturers.
