UNMANNED AERIAL VEHICLE FOR PESTICIDE APPLICATION IN PRECISION HORTICULTURE Russian patent published in 2023 - IPC B64U10/10 B64U101/40 A01M7/00 B64D1/18 

FIELD: agriculture; unmanned aerial vehicles (UAVs).

SUBSTANCE: agriculture, in particular helicopter-type unmanned aerial vehicles (UAVs) for differentiated pesticide treatment of fruit trees and berry bushes in precision gardening. UAV contains mechanisms for extending and retracting the links of the rod sections. The U-shaped section bar is made in form of interconnected horizontal and vertical telescopic sections with an odd number of links, installed with the possibility of simultaneous uniform extension of all links, except for the first fixed ones, non-contact ultrasonic distance sensors are installed on the central odd links of the sections and at the ends of the vertical sections, and the even links of the sections are equipped with spectral recognition sensors connected by communication lines with the controller. The extension-retraction mechanisms of the links of the vertical sections are installed at the ends of the last links of the horizontal sections of the rod, and for the horizontal sections - in the central part of the body. The nozzles are installed with a step that provides the possibility of overlapping the spray torches from adjacent nozzles by at least three quarters of the width of the torch of one of them.

EFFECT: quality of processing increases, consumption of pesticides decreases, and yield increases.
