Problems solved by technology

Because the canopy of leaves is too high, it is impossible to use ground machinery or manual spraying to prevent and control pests and diseases. If small drones are used for aerial spraying operations, there will be a problem that the density of trees will be high, which will limit the flying space of aircraft. At the same time, it is not suitable to use Large aircraft, so 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, U

Embodiment 1

[0041] The structure of a detachable ring-column hollow UAV described in this embodiment is as follows: figure 1 As shown, it includes frame, power and control mechanism, spraying operation executive mechanism and central fastening device, and each part will be described in detail in conjunction with the accompanying drawings.

[0042] The frame includes a fixed plate 11 , a machine arm 12 and a foot support column 13 . Described fixed disk 11 is double-layer, detachable, hollow structure, can contain various size apertures, inner diameter and outer diameter are circular, and inner diameter is slightly larger than the maximum diameter of working tree trunk. The fixed plate is divided into an upper plate and a lower plate. There are supporting aluminum columns between the upper plate and the lower plate. A part of the supporting aluminum columns is distributed along the outer diameter of the inflatable and deflated airbag, and a part of the supporting aluminum columns is arrang...

Embodiment 2

[0060] Present embodiment except following feature other structures are with embodiment 1:

[0061] like Figure 5 As shown, the medicine box in the spraying operation executive mechanism 3 is to comprise the common drone onboard medicine box 38, and the said drone onboard medicine box 38 is suspended below the body, and when the drone flies upwards, along with Fly to tree trunks to spray. This embodiment can reduce the length of the connecting hose and the pressure of the water pump.

Embodiment 3

[0063] Present embodiment except following feature other structures are with embodiment 1:

[0064] see Figure 6 The operation implementing mechanism described in this embodiment is a manipulator operating mechanism for performing picking operations, which includes several manipulators 39 and manipulator control devices. The 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.

Abstract

The invention discloses a detachable ring-pillar type hollow unmanned aerial vehicle and an operation method thereof. The unmanned aerial vehicle comprises a rack, a power and control mechanism and a central fastening device, wherein the rack comprises a fixing disc and at least two engine arms, the fixing disc has a double-layer, detachable and hollow structure, the starting end of each engine arm is fixed on the fixing disc and is symmetrically distributed along a detachable line on the fixing disc; the power and control mechanism comprises upper paddle rotor wings, upper paddle motors, upper paddle electronic speed regulators and flight control modules; the upper paddle rotor wings are arranged at the tail ends of the engine arms and are driven by the upper paddle motors, the downward wind power is generated by rotation, the flight control modules are used for controlling the rotation of the upper paddle motors through the upper paddle electronic speed regulators; the central fastening device is used for fastening an unmanned aerial vehicle on an operation trunk when the upper paddle rotor ring stops rotating. According to the detachable ring-pillar type hollow unmanned aerial vehicle, the fixing disc is sleeved on the outer diameter of the operation trunk to operate, and when the appointed height is reached, the fastening device is used for fastening the unmanned aerial vehicle on the operation trunk; and the detachable ring-pillar type hollow unmanned aerial vehicle has the advantage of energy saving.

Description

technical field [0001] The invention relates to the field of forestry machinery equipment research, in particular to a detachable ring-column hollow unmanned aerial vehicle and an operating method thereof. Background technique [0002] Trees with tall and straight trunks are ubiquitous in our country. Taking the common king coconut in tropical areas as an example, its tree height can reach 20 meters and its trunk is straight. It is a world-renowned tropical tree species, usually used as street trees or group planted as green spaces landscape tree. Because the canopy of leaves is too high, it is impossible to use ground machinery or manual spraying to prevent and control pests and diseases. If small drones are used for aerial spraying operations, there will be a problem that the density of trees will be high, which will limit the flying space of aircraft. At the same time, it is not suitable to use Large aircraft, so the drug loading capacity is small. In addition, the airc...
