UNMANNED AERIAL VEHICLE FOR DETERMINING CONTENT OF PLANT NUTRIENTS IN SOIL Russian patent published in 2024 - IPC B64U101/40 G01N33/24 

FIELD: aviation.

SUBSTANCE: unmanned aerial vehicle (UAV) for determining the content of nutrients of plants in soil comprises a housing, connected to it radial brackets, engines, propellers, a power supply system with a battery, landing gear, onboard system of automatic control of piloting, navigation and payload, process module attached to the housing by means of brackets. Process module comprises a linear servo drive fixed in the lower part of the UAV, a rod with a reversible electric drive attached to it, connected to a soil drill, step reversible electric motor with a drive shaft, at the end of which there is an L-shaped rotary drain device with a shut-off electrohydraulic valve connected by a flexible hydraulic line to a hydraulic pump connected to a hydraulic tank, linear actuator, on the rod of which there is a reversible step electric drive connected by means of an L-shaped stand with a sensor fixed on it, having at least three probes for determining content of available nitrogen (N), phosphorus (P) and potassium (K) in soil in real time.

EFFECT: enabling increase in the technological operation efficiency, reduction of labour costs and time for determination of plant nutrients content in the soil during the whole period of crops cultivation.
