Unwinding mechanism of rotating operation device

The invention provides a rotating shaft unwinding device which comprises a connection part, an action part, a rotating shaft, an unwinding rod and an operation component, and the unwinding rod is hidden inside the rotating shaft and can radially move while rotating along with a rotating rod to drive an unwinding blade to cut foreign matter wound on the rotating shaft to achieve the objective of unwinding. Further, different unwinding rods and blades can be designed according to different rotating mechanisms to ensure dynamic balance and no increase of extra resistance. The unwinding device canbe used for all rotating mechanisms like a tapping machine, a rotary tiller, a harvester, a smashing tiller and propellers on a ship in agriculture and forestry and devices prone to being wound by crops, water plants and fishing nets to achieve the objectives of reducing power loss, reducing shutdown time or reversal unwinding time and improving operation efficiency. 本发明提供一种旋转轴除缠绕装置，包括连接部件、动作部件、旋转轴、除缠杆、作业组件，所述除缠绕杆藏在旋转轴的里
