Pesticide spraying unmanned aerial vehicle and spraying method

Abstract

The invention discloses a pesticide spraying unmanned aerial vehicle and a spraying method. The pesticide spraying unmanned aerial vehicle comprises a battery box, a flight control box, propeller moment arm modules, spraying pipe modules, a water tank, a pressure pump module, a square bracket module and a supporting plate, wherein the battery box is fixedly connected with the flight control box; and the battery box and the flight control box are both fixed on the square bracket module; the propeller moment arm modules can be fixed at four end parts of the square bracket module in a folded way; the water tank is clamped between the square bracket module and the supporting plate; one end of the pressure pump module extends into the water tank; the other end of the pressure pump module is connected with the spraying pipe modules; the water tank is a sealed compressible water tank; under a circumtance that the propeller moement arm modules provide lift forces, the unmanned aerial vehicle takes off, the pressure pump module pumps a pesticide solution out of the water tank and the pesticide solution is sprayed through the spraying pipe modules; and the volume of the water tank is gradually reduced with the reducing of the pesticide solution. According to the invention, a technical problem of intelligent pesticide spraying on large-area farmlands is solved; and physical and psychological healths of operators are maintained while time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of spraying drones, in particular to a pesticide spraying drone and a spraying method thereof. Background technique [0002] In order to effectively combat diseases and protect the healthy growth of crops, it is necessary to spray pesticides to kill pests and prevent crop production reduction. Due to the different feeding and feeding methods of different pests, the mouthparts are also different, mainly including chewing mouthparts and piercing-sucking mouthparts. Chewing mouthparts pests, such as beetles, locusts and moth and butterfly larvae. They all feed on solid food, harm roots, stems, leaves, flowers, fruits and seeds, and vegetables, and cause mechanical damage, such as nicks, holes, snapping, drilling stems, cutting off roots, etc. Piercing-sucking mouthparts pests, such as aphids, scorpions, leafhoppers and mites. They use needle-like mouthparts to pierce plant tissues to suck food, causing plant...

AI Technical Summary

Problems solved by technology

In the entire pesticide spraying operation, the labor intensity of the operator is huge, and the operator is directly exposed to the pesticide, so the person is extremely vulnerable to the injury of the pesticide. At the same time, due to manual operation, the efficiency of the entire pesticide spraying operation is not high
