The ship unloader is a heavy port mechanical equipment specially used for unloading cargos from a ship, which includes a belt conveyor and a corresponding belt conveyor gallery 30. The gallery 30 is a long and narrow passage for placing the belt conveyor. In order to improve the productivity of the ship unloader, many existing ship unloaders are provided with multiple belt conveyor galleries 30 to meet the operation requirements of simultaneously unloading different berths of the ship by multiple ship unloaders of the terminal. This requires the ship unloader to be designed with a rotary belt conveyor to meet the simultaneous operation requirements of different berths of the terminal.
