Title:
UNLOADER
Document Type and Number:
WIPO Patent Application WO/2014/024563
Kind Code:
A1
Abstract:
An unloader is provided with: a bucket elevator (9) for unloading bulk material (M); a boom conveyor (39) for conveying the bulk material (M) unloaded by the bucket elevator (9); a drop section (60) for dropping the bulk material (M) conveyed by the boom conveyor (39); and a blade wheel (65), a speed increasing gear (66), and an electric power generator (67), which convert the drop energy of the bulk material (M) into electrical energy, the bulk material (M) dropping through the drop section (60). Thus, the potential energy of the bulk material (M), which the bulk material (M) has when the bulk material (M) is unloaded, is converted into electrical energy when the bulk material (M) is dropped, and the obtained electrical energy can be utilized.
