Agricultural spraying multi-rotor wing unmanned aerial vehicle

Abstract

The invention provides an unmanned aerial vehicle capable of being applied to small scattered farmlands in the south to carry out pesticide spraying. The unmanned aerial vehicle comprises a rack, rotor wings and a rotor wing motor. The unmanned aerial vehicle is characterized in that a medical tank is also arranged below the rack; the upper part of the medical tank is clamped with the rack through a plurality of claws; support legs and electric nozzles are arranged below the medical tank; the support legs are of a horn mouth structure which gradually expands downwards; the electric nozzles are arranged in the support legs, and are electrically connected with an information processor; a stirring device is also arranged on the medical tank, and comprises a stirring cage, a stirring shaft, a coupler and a stirring motor; the stirring shaft is inserted into the medical tank; the stirring cage is fixed on the stirring shaft; the stirring motor is arranged on the rack and is electrically connected with the information processor; the stirring motor is a two-axis motor; the lower end of the stirring motor is connected with the coupler; the upper end of the stirring motor is also connected with an expanding rotor wing; the motor of the electric nozzles is a motor which can be switched between forward and backward rotation; a liquid level sensor and a temperature sensor are arranged in the medical tank.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an agricultural spraying multi-rotor unmanned aerial vehicle used in the civilian field. Background technique [0002] A drone is an unmanned aerial vehicle operated by a radio remote control device or its own program control device. It first appeared in the 1920s, when it was used as a target drone for training. is a term used by many countries to describe the latest generation of unmanned aircraft. Literally, the term can describe cruise missiles that have evolved from kites, radio-controlled aircraft, and V-1 missiles, but in military terms it is limited to reusable heavier-than-air vehicles. UAVs have a wide range of uses, low cost, good cost-effectiveness ratio; no risk of casualties; strong survivability, good maneuverability, and easy to use. They play an extremely important role in modern warfare and have broad prospects in the civilian field. From a technical point of vie...

AI Technical Summary

Problems solved by technology

This kind of landform is not like the flat land in the north. Unmanned fixed-wing aircraft cannot be used for spraying, so many farmers in the south use manual spraying; manual spraying needs to reserve walkways in the rice fields, which reduces the utilization rate of the rice fields. Farmers need to walk back and forth in the rice fields when spraying pesticides, which has a certain impact on the growth of crops; in summary, there is an urgent need for a drone that can be used in small scattered farmlands in the south for pesticide spraying
