ABSTRACT:
An axial-flow thresher-separator unit for combine harvesters comprises at least one elongate member for cleaning the outer surface of the separator casing which extends parallel to the axis of the thresher-separator cylinder and is movable on the outer surface of the separator casing. The elongate member is connected to a pair of chains driven by gears. Means are arranged to transmit an alternating rotary movement to the gears. Each chain is an open loop and is guided within a double rail constituted by two parallel strips located above and beneath the pins of the chain. The longitudinal edges of each strip slidably engage the facing surfaces of the two plates constituting each inner link of the chain.
