CONVEYOR SYSTEM FOR VESSEL SHIPPING OF AGGREGATE FOR SHORTENING THE WORKING HOURS

摘要

PURPOSE: A conveyor system for vessel shipping of aggregate is provided to improve the efficiency in the transporting work of sand by transporting a large quantity of sand at a time to a transport vessel, in transporting sand of sand-gathering vessels to the transport vessel via conveyors. CONSTITUTION: A conveyor system for vessel shipping of aggregate is installed to the surface of a barge(300). First and second variable conveyors(100a) are installed to the front end of the surface of the barge parallel. The angles of the first and second variable conveyors are adjusted in a state of being supported to a support tower. First and second fixed conveyors(100b), the front ends of which are arranged on the ends of the first and second variable conveyors, are installed to the rear of the first and second variable conveyors to a predetermined height in a parallel state. Plural hoppers(130) installed at a predetermined interval and plural supports(700) thoroughly crossing the second fixed conveyor from the first fixed conveyor are installed on the top of the first and second fixed conveyors, to enable a folk lift to move to sand-gathering vessels of the sides of the barge. A winch(320) for a wire or a hydraulic cylinder is used as a unit for adjusting the angles of the first and second variable conveyors.
