Abstract

PURPOSE:To increase the space in a hold and increase the loading efficiency by installing an air jetting means directed to a carrying-out conveyor arranged in the longitudinal direction of a hull and onto the hopper surface on the bottom part of the hold, onto the bottom part of the hold, and reducing the inclination angle of the hopper on the bottom part of the hold. CONSTITUTION:In the hold structure, a bulk-load carrying-out conveyor 16 which extends in the longitudinal direction of a hull 13 is installed onto the bottom plate in a hold 17, and a hopper-shaped bottom plate is provided towards the conveyor 16. An injection part 19 for jetting air towards the carrying-out conveyor 16 is installed onto a hopper-shaped bottom plate 18. Therefore, the bulk-load on the hopper-shaped bottom plate 18 can be transferred onto the carrying-out conveyor 16 by the jetted-out air, and the inclination angle of the hopper-shaped bottom plate can be reduced. Therefore, the loading space in the hold can be increased, and the loading efficiency can be improved.
