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.

Abstract: Disclosed a large-span bulk material conveying system, including a folding arm conveyor and a dike-striding elevation-type feeding conveying device. The folding arm conveyor is mainly composed of an undercarriage mounted on the ground of a stockyard, a tower body mounted on the undercarriage and provided with a gyration apparatus and a hopper, a balance arm provided with a balance trolley, a conveying arm provided with a portal frame I, a portal frame II and an unloading trolley, a tower top and other main components, wherein the balance arm, the conveying arm and the tower top are mounted on the tower body. The folding arm conveyor can rotate horizontally, and the conveying arm can be folded and retracted by controlling the wire rope by the windlass, so that the folding arm conveyor can be prevented from colliding with other devices or buildings during the rotation.

Abstract: The invention employs a folding arm conveyor that rotates horizontally. The folding arm conveyor is mainly composed of an undercarriage mounted on the ground of a stockyard, a tower body mounted on the undercarriage, a balance arm, a conveying arm, a tower top, and other main components, wherein the balance arm, the conveying arm, and the tower top are mounted on the tower body. The conveying arm is provided with two portal frames (I) and (II) and an unloading trolley. The tower body is provided with a gyration apparatus and a hopper. The balance arm is provided with a balance trolley. The folding arm conveyor can rotate horizontally, and the conveying arm can be folded and retraced by controlling the wind rope by the windlass, so that the folding arm conveyor can be prevented from colliding with other devices or buildings during the rotation.
