Intelligent plant protection unmanned aerial vehicle with accurate spraying and used for agricultural production

Abstract

The invention relates to an intelligent plant protection unmanned aerial vehicle with accurate spraying and used for agricultural production. The unmanned aerial vehicle includes a main body, a spraying mechanism, multiple flight mechanisms and multiple wind-guiding mechanisms; the flight mechanisms include telescoping assemblies, side rods and flight assemblies; each telescoping assembly includesa driving unit, a connection board and two telescoping units; and each wind-guiding mechanism includes a fixing plate, a wind-guiding plate, a second motor, a second connecting rod, a third connecting rod and a third articulated block. According to the unmanned aerial vehicle, the flight assemblies can move outward through the telescoping assemblies in the flight mechanisms, so that air flow canbe prevented from deforming leaves of crops when pesticide is sprayed, and the crops can normally absorb the pesticide when the unmanned aerial vehicle flies away; and as the angles of wind-guiding plates can be changed through the wind-guiding mechanisms, an air flow directions under rotors can be adjusted, so that influences on the pesticide and the crops when the pesticide is sprayed can be prevented, and therefore, the accuracy of spraying the pesticide can be further guaranteed, and the practicality of equipment can be enhanced.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an intelligent plant protection unmanned aerial vehicle with precise spraying for agricultural production. Background technique [0002] Unmanned aerial vehicle, unmanned aerial vehicle (UAV) for short, is a new concept weapon equipment in rapid development, which has the advantages of flexible maneuvering, quick response, unmanned flight, and low operation requirements. UAVs equipped with multiple types of sensors can realize real-time image transmission and detection of high-risk areas, which is a powerful supplement to satellite remote sensing and traditional aerial remote sensing. 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,...

AI Technical Summary

Problems solved by technology

[0003] In the existing plant protection drones, the drones fly above the crops to spray pesticides on the crops, which not only saves labor costs, but also has faster and more efficient spraying of pesticides than human spraying. , but when the drone is flying, the wind generated by the rotation of the rotor will distort and deform the leaves of the crops. Therefore, when the drone flies away, the crops will bounce back the droplets deposited on the crops in order to restore their original state. As a result, the droplet adhesion rate is reduced, the pesticide cannot stay on the leaves of the crops accurately, the spraying effect is reduced, and the practicability of the drone is reduced.
