Abstract

The invention realises a milling drum (1; 100; 200) for scarifier machines which comprises a plurality of annular elements (4, 5) coaxially arranged outside a core (2) connected with the driving shaft of the scarifier machine, supplied with operating protruding elements (6) arranged like a spiral and suitable for shuttering the soil to remove. Said annular elements comprise at least two ending annular elements (3) realised one - piece and one or more intermediate annular elements (4, 5) in between said ending annular elements (3), where at least one (4) of said one or more intermediate annular elements is formed of at least two shells (41) supplied at the ends with radial flanges (411) opposable among them which are united by fastening means (412) in order to render these annular elements (4, 5, 3) integral among them and with said core (2). <IMAGE>
