[0002] Ship unloader is a device for loading and unloading materials on board. It grabs the materials in the ship through the hopper and then transports them out of the ship. The common chain bucket ship unloader solves the problems of material leakage and dust caused by the traditional grab bucket ship unloader during use. It has outstanding environmental advantages and is widely used in bulk cargo unloading terminals in ports.

[0003] When grabbing materials, the existing chain bucket ship unloader will push the materials outward, causing the materials to scatter after grabbing, making it inconvenient to grab the materials next time.
