A ring-grip spraying drone suitable for thinning branches of tall crowns and its spraying method

Abstract

The invention relates to a ring-handled spraying unmanned aerial vehicle suitable for thinning branches of tall crowns, which includes a frame, a power and control mechanism that provides flight power through rotors, and a spraying operation actuator, and the spraying operation actuator is installed on the frame ; It also includes a hook fastening device for fastening the drone on the branch when the rotor stops rotating, and the hook fastening device is installed on the frame; the power and control mechanism includes a flight control module for control. It also relates to a pesticide application method of a ring-handled pesticide application drone suitable for high crown thinning. The invention hangs the unmanned aerial vehicle on the working branch for operation, and after reaching a specified height, the hook fastening device fastens the unmanned aerial vehicle on the working branch, has the advantage of energy saving, and 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.
