Adjusting device and method for consistency of wind field and fog field of rotor of planting protection unmanned aerial vehicle

Abstract

The invention discloses an adjusting device and method for the consistency of a wind field and fog field of a rotor of a planting protection unmanned aerial vehicle. The adjusting device comprises a data collection module, a data processing module and a position regulating mechanism, wherein the position regulating mechanism comprises an X-direction adjustment mechanism, a Y-direction adjustment mechanism and a Z-direction adjustment mechanism, the Z-direction adjustment mechanism comprises a Z telescopic rod and a Z telescopic driving piece, the X-direction adjustment mechanism comprises an Xtelescopic rod and an X telescopic driving piece, a spray head is arranged on the X telescopic rod, and the Y-direction adjustment mechanism comprises a Y telescopic rod and a Y telescopic driving piece. The adjusting method comprises the steps that the data collection module obtains flight parameters of the unmanned aerial vehicle and sends the flight parameters to the data processing module; the data processing module processes the flight parameters, generates a regulating command and sends the regulating command to the position regulating mechanism; the position regulating mechanism regulates the position of the spray head according to the regulating command; the planting protection unmanned aerial vehicle lands. The adjusting device and method for the consistency of the wind field andfog field of the rotor of the planting protection unmanned aerial vehicle can fully utilize the wind field of the rotor to assist in the settlement of fog droplets to reduce the drift of the fog droplets.

Description

technical field [0001] The invention relates to a precision agricultural device, in particular to an adjusting device and method for planting and protecting the consistency between the wind field and the fog field of the rotor of an unmanned aerial vehicle. Background technique [0002] In recent years, plant protection drone spraying has been widely used in agriculture due to its advantages of low operating cost, strong assault capability, safe operation, and no restrictions on crop growth; as one of the important symbols of agricultural aviation, plant protection drones The man-machine aerial spraying operation method has been rapidly applied and developed. [0003] Plant protection drones mainly include two types: fixed-wing drones and rotary-wing drones. Among them, rotary-wing drones are the most widely used because they can hover in the air and do not need other auxiliary take-off and landing devices. Generally, in the spraying operation, the nozzle of the rotor UAV i...

AI Technical Summary

Problems solved by technology

Generally, in the spraying operation, the nozzle of the rotor UAV is installed directly below the rotor, so that the wind field generated by the rotor can assist the settlement of the droplets. Drift is not easy to occur at this time if the movement speed is large; but with the influence of resistance, the movement speed of droplets gradually decreases and tends to zero, and drift is very easy to occur at this time

Therefore, in response to the above problems, people began to look for ways to reduce the drift of droplets in aerial spraying operations, for example, adding charges to the droplets or adding deposition aids to the liquid medicine, etc., but the results achieved were minimal and could not be effective. Minimize droplet deflection
