Description

An agricultural drone

technical field

The utility model relates to the technical field of unmanned aerial vehicles, in particular to an agricultural unmanned aerial vehicle.

Background technique

Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. From a technical point of view, it can be divided into: unmanned helicopter, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airship, unmanned parawing aircraft, etc. At present, the scope of use of UAVs has been expanded to the three major fields of military, scientific research, and civilian use, specifically in power, communications, meteorology, agriculture, ocean, exploration, photography, disaster prevention and reduction, crop production estimation, anti-drug anti-smuggling, border patrol, Public security and anti-terrorism are widely used. UAVs can be used for low-altitude agricultural monitoring, plant protection, and auxiliary pollination for crop seed production. The most used in plant protection is to spray pesticides, which is a hundred times faster than manual spraying, and can avoid the danger of poisoning caused by manual spraying. The drone medicine boxes currently on the market need to be pressurized by air pumps, and then the pesticides are released from the air through the pressure device. The spray nozzle sprays out, and some drones use a single spray head, the spray area is small, and the work efficiency is low.
