PURPOSE:To accommodate grain cargo even in the dead spaces of grain cargo conveyed through a hatch formed in upper corners of a hold by providing a screw conveyor movable along a hatch opening at the upper side in a hold beneath an upper deck around the hatch section. CONSTITUTION:A screw conveyor 7 is arranged at the upper corner in a hold 3 beneath an upper deck 1 around a hatch 5. The screw conveyor 7 is installed so as to be movable along the hatch 5 opening. The grain cargo conveyed through the hatch opening 5 creates dead spaces without being spread to the upper corners in the hold based on an angle of repose theta, but by using a screw conveyor free of moving along the hatch opening, the grain cargo can be conveyed even to the dead spaces, and the loading efficiency can be improved. In addition, the grain cargo can be prevented from moving, and the ship can be stabilized. |
