Mist spray anti-drifting device for agricultural unmanned aerial vehicle and method for applying mist spray anti-drifting device

Abstract

The invention discloses a mist spray anti-drifting device for an agricultural unmanned aerial vehicle and a method for applying the mist spray anti-drifting device.The mist spray anti-drifting device comprises a control end, three driving devices and a support rod assembly.The control end comprises a transmitter and a receiver, the driving devices comprise power devices, transmission gears and bases, the support rod assembly comprises a main support rod, a left support rod and a right support rod, and the three driving devices are respectively arranged between the main support rod and an unmanned aerial vehicle body, between the main support rod and the left support rod and between the main support rod and the right support rod and can drive the support rod assembly to be folded and unfolded under the control of the control end; pesticide delivery hoses are arranged in the various support rods of the support rod assembly, and mist spray nozzles are arranged at corresponding positions of the left support rod and the right support rod.The mist spray anti-drifting device and the method have the advantages that the designed support rods are of unfolding and folding structures, can be folded when operation is not carried out and can be unfolded when spray and application operation is carried out; the nozzles are lowered, so that sprayed and applied fog drop can be kept away from influence of wind fields, accurate aviation spray and application operation can be carried out, and the mist spray anti-drifting device is simple in structure and easy and convenient to operate and is small and safe.

Description

technical field [0001] The invention relates to the field of precision agricultural equipment research, in particular to an agricultural unmanned aerial vehicle spray anti-drift device and its use method. Background technique [0002] In recent years, due to the advantages of agricultural drone spraying, such as low operating cost, strong assault capability, safe operation, and not being restricted by crop growth, the aerial spraying operation method, which is one of the important symbols of agricultural aviation, has been rapidly applied and accepted. develop. [0003] With the gradual expansion of the scope of agricultural UAV spraying operations, some disadvantages and shortcomings of agricultural UAV aerial spraying methods are gradually exposed. Among them, the severe drift of liquid medicine caused by external wind field and rotor wind field has become the focus of attention. When the flying height of the UAV is high, the external wind field factors have a great infl...

AI Technical Summary

Problems solved by technology

When the flying height of the UAV is high, the external wind field factors have a great influence on the droplet deposition, making it unable to effectively deposit in the target area; when the flying height of the UAV is too low, the rotor wind field factors have a great influence on the droplet deposition The impact is large, the turbulent wind field makes the crops shake violently and cannot effectively apply the medicine, and when the flying height is too low, it is not safe for the drone itself, and it is easy to crash into objects and crash

At present, many scholars have begun to find ways to reduce droplet drift in aerial spraying operations, such as reducing droplet drift by adding charges to droplets, adding deposition aids to liquid medicine, and trying to grasp the distribution of droplet deposition. but little effect
