The bucket also includes enclosures (4) for a transmission and bearing assemblies of the working drums (3), said enclosures being defined by frame panels (5) capable of being fitted with bearing cups (6) for the drums (3). Tool flanges (11) are provided with a butt collar or butt expansion (12a), extending around the drum shaft (9, 10) and dimensioned in the drum shaft direction in such a way that, with the tool flanges (11) at a desired distance from each other, between the butt collars (12a) remains a gap (s) for a welded joint.
