 The utility model adopts an integrated structure of a ship unloader, a ship loader and an intermediate belt conveyor. When the bridge type loading and unloading ship machine is in the barge operation, first, the tilting boom of the ship unloader moves to the top of the ship to be unloaded, and the grab is discharged from the ship. After the ship's ship grabs the material and raises it to a certain height, the trolley on the tilting arm frame drives the grab to walk along the tilting arm. After reaching the top of the funnel, the car stops, the grab falls to the designated position to unload the material, and the material is loaded. Into the funnel; the material in the funnel is dropped by the vibrating feeder onto the conveyor belt of the lower intermediate belt conveyor, and the intermediate belt conveyor conveys the material from the funnel end to the telescopic boom conveyor of the ship loader; the telescopic belt conveyor passes the rotation The movements such as pitching and telescoping are adjusted to the top of the cabin to be loaded, and then the material is loaded onto the ship to be loaded by the roller.
