Abstract
Perforated rotating attraction drum of a general cylindrical shape and featuring openings, this drum being fitted for being mounted on a leaf-stripping head of the leaves of a foliage wall such as a row of vine-stock, characterized in that it features the superposition of a plurality of rings presenting an outside cylindrical surface, and of a plurality of annular openings made between two successive rings, these openings allowing the passage of a suction air flow across and towards the inside of the perforated rotating attraction drum featuring, internally, means of rigid assembly of the plurality of stacked rings and a coupling means to a motorization for its rotational drive.
Claims14
A perforated rotating attraction drum for mounting to a leaf-stripping head used for stripping leaves of a foliage wall, the perforated rotating attraction drum comprising:
- a plurality of rings that are superimposed upon each other, said plurality of rings defining a cylindrical exterior surface;
- a plurality of openings respectively formed between successive rings of said plurality of rings, said plurality of openings allowing an axial passage of a suction airflow through an interior of said plurality of rings to an end of the perforated rotating attraction drum, said plurality of rings being rigidly assembled together;
- and
- a coupler positioned internally of said plurality of rings, said coupler adapted to couple said plurality of rings to a motor of the leaf-stripping head.
