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.

Embodiment 1

[0043] A ring-handled spraying unmanned aerial vehicle suitable for thinning branches of tall crowns includes a frame, a power and control mechanism, a spraying operation executing mechanism, and a hook fastening device.

[0044] The frame includes a fixed disk 11 and a machine arm 12 . The fixed plate 11 is a non-detachable interlayer structure with built-in battery, electronic governor, flight control module, battery, water pump main body and spray operation controller, air pump and its control module, etc. The starting end of each machine arm 12 is fixed on the fixed plate 11 and distributed symmetrically, and the upper surface of the machine arm 12 and the fixed plate 11 is basically kept horizontal. The objects placed inside the fixed disk 11 are evenly weighted along the center, and the center of gravity of the whole drone is at the joint between the hook fastening device and the fixed disk.

[0045] The power and control mechanism includes a motor base 21, a motor 22, ...

Embodiment 2

[0062] In this embodiment, the medicine box is placed on the ground, and the medicine box and the water pump are connected through a connecting hose.

[0063] The parts not mentioned in this embodiment are the same as those in Embodiment 1.

Embodiment 3

[0065] On the basis of Embodiment 1, in this embodiment, a manipulator operation actuator is installed on the fixed plate, which includes two manipulators and a manipulator control device. The manipulators are distributed on the upper part of the fixed plate, respectively connected with the manipulator control device, and the manipulator control device is connected with the flight control module. The flight control module receives external operation instructions and controls the manipulator to complete picking and other actions.

[0066] The parts not mentioned in this embodiment are the same as those in Embodiment 1.

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...
