Abstract: The present invention discloses a method for operating a multi-bar linkage mechanism based conveyor. Stretching the mechanism based conveyor comprises: an automatic control system is started to control a first two-drum winch, a second two-drum winch, and hydraulic cylinders in a multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters an operating state, and the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom stop operating. Then, the angle of the multi-bar linkage mechanism based conveyor boom can be adjusted by controlling the operation of the second two-drum winch. Retracting the mechanism based conveyor comprises: the automatic control system is started to control the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters a non-operating state.
