Circularly holding type medicine applying unmanned aerial vehicle for high-crown thinning and pesticide applying method thereof

Abstract

The invention relates to a circularly holding type pesticide applying unmanned aerial vehicle for high-crown thinning. The unmanned aerial vehicle comprises a rack, a power and control mechanism, an atomizing operation executing mechanism and a suspension hook fastening device, wherein the power and control mechanism is used for providing fly power through rotor wings, the atomizing operation execution mechanism is installed on the rack, the suspension hook fastening device is used for fastening the unmanned aerial vehicle on twigs when the rotor wings cease to rotate, the suspension hook fastening device is installed on the rack, and the power and control mechanism comprises a flight control module used for controlling. The invention further relates to a pesticide applying method of the circularly holding type pesticide applying unmanned aerial vehicle for high-crown thinning. According to the unmanned aerial vehicle, the unmanned aerial vehicle is hung on to-be-operated twigs to perform operation, after the unmanned aerial vehicle reaches a certain height, the unmanned aerial vehicle is fastened on the to-be-operated twigs, the unmanned aerial vehicle has the advantages of energysaving, and the unmanned aerial vehicle belongs to the technical field of forestry machinery equipment.

Description

technical field [0001] The invention relates to the field of forestry machinery equipment research, in particular to a ring-handled spraying unmanned aerial vehicle and a spraying method suitable for tall crown thinning branches. Background technique [0002] Trees with high crowns and sparse branches are common in our country. Take the common poinciana in tropical areas as an example. Its tree height can reach 20 meters, and its branches open in a wide umbrella shape. It is a famous tropical species and is usually used as a street tree or group planting. Used as a landscape tree for green spaces. Because the leaf canopy is too high and the branches are criss-crossed, it is impossible to use ground machinery or manual spraying methods to prevent and control pests and diseases. If small drones are used for aerial spraying operations, there will be a problem of high forest density that limits the flying space of the aircraft. Simultaneously because it is unsuitable to adopt l...

AI Technical Summary

Problems solved by technology

Because the leaf canopy is too high and the branches are criss-crossed, it is impossible to use ground machinery or manual spraying methods to prevent and control pests and diseases. If small drones are used for aerial spraying operations, there will be a problem of high forest density that limits the flying space of the aircraft. At the same time, because it is not suitable to use large aircraft, the drug loading capacity is small

In addition, the plane generally flies in the upper part of the canopy, so the lower part of the leaf surface cannot be effectively sprayed.

[0003] At present, in the field of agriculture, UAVs used in various operations generally have the characteristics of unlimited movement space, but when they hover in the air, the rotor must rotate to provide a lift that overcomes gravity, thereby ensuring the hovering of the UAV in the air. or flight attitude, which produces a lot of energy consumption and will inevitably reduce the payload

In addition, an expensive attitude control system must be used to ensure the balance of the body during operation. At the same time, the control method of variable operation must be satisfied. The control method is complicated and the effect is not good.
