Background technique

The screw ship unloader is a high-efficiency continuous bulk cargo ship unloader mainly composed of three parts: a feeding head, a vertical screw conveying section and a horizontal screw conveying section. During operation, the material is squeezed into the bottom of the vertical conveying pipe by counter-rotating the feeding head, and then the material spirals up under the agitation of the vertical spiral blades. After reaching the horizontal spiral, it is transported to the designated material concentration bin, thereby completing the conveying process.

During the process of transporting materials, waves may cause the hull to rock. When there is less material at the bottom of the cabin, that is, when the height of the material is only 50 cm, if the hull shakes, the feeding head of the screw unloader may collide with the bottom of the cabin.
