  • Agricultural separating device and agricultural separator
    Patent number: 6237778
    Abstract: An agricultural separating device has a starshaft (7) comprising a row of resilient starwheels (2) mounted on a rotatable shaft. Rings (5) formed of a rigid material (e.g. nylon or polypropylenes), and having an outer diameter such that they extend radially along 40-80% of the radial length of the fingers (4) of the starwheels (2), are mounted between adjacent starwheels (2) so as to close off the radially inner space between the fingers (4) without reducing the length and therefore flexibility of the fingers (4).
