To perform tree cutting work efficiently and safely.SOLUTION: One end of a wire saw is attached to an unmanned aerial vehicle, the unmanned aerial vehicle is flown toward a branch to be cut while holding the other end of the wire saw on the ground and is allowed to pass over the branch to hang the wire saw over the branch, and the unmanned aerial vehicle is lowered to remove the one end of the wire saw from the unmanned aerial vehicle, and the branch is cut by repeating an operation of pulling the one end and the other end of the wire saw alternately while bringing the wire saw into contact with the branch. The unmanned aerial vehicle has a main body having one or more rotors, and a wire saw attachment mechanism, and the one end of the wire saw is attached to the unmanned aerial vehicle by the attachment mechanism so that it is located on an outer peripheral side of the rotors. The attachment mechanism has an arm extending to an outer peripheral direction of the unmanned aerial vehicle, and a hook provided at a tip of the arm, to which one end of the wire saw is hooked.SELECTED DRAWING: Figure 1
【課題】樹木の伐採作業を効率よく安全に行う。【解決手段】ワイヤーソーの一端を無人航空機に取り付け、ワイヤーソーの他端を地上で保持しつつ無人航空機を伐採の対象となる枝に向けて飛行させ、枝の上方を通過させることによりワイヤーソーを枝に掛け、無人航空機を降下させてワイヤーソーの一端を無人航空機から取り外し、ワイヤーソーを枝に接触させつつ、ワイヤーソーの一端及び他端を交互に引く操作を繰り返すことにより枝を切断する。無人航空機は、一つ以上の回転翼を有する本体と、ワイヤーソーの取付機構と、を備え、ワイヤーソーの一端を、回転翼よりも外周側に位置するように上記取付機構により無人航空機に取り付ける。上記取付機構は、無人航空機の外周方向に延出するアームと、アームの先端に設けられ、ワイヤーソーの一端が掛止されるフックと、を有する。【選択図】図1
