To secure sufficient durability of a trough by coping with vertical deformation of a hull in regard to a conveyor device including the trough arranged in the longitudinal direction of the hull of a self-unloader barge.
The conveyor device 2 includes: a trough 5 placed in a self-unloader barge, arranging the longitudinal direction of the trough 5 in the longitudinal direction of the hull; and a chain conveyor 3 built in the trough 5. The trough 5 is formed by connecting a plurality of trough units 5a in the longitudinal direction, and a rubber packing 71 as a shock absorbing member capable of elastically deforming at least in the longitudinal direction of the trough 5 is interposed in each connection part between the trough units 5a, so that at least one part of a compression load in the longitudinal direction of the trough 5, which is generated with the deformation of the hull bent downward in a central part thereof, can be absorbed by the elastic deformation of the shock absorbing members.
