Abstract: A sweep conveyor assembly is provided for use in a silo or granary (70) having a floor (71), a generally cylindrical wall (72) upstanding from the floor (71) and a discharge apparatus (1) for discharging material (74) from a centre of the floor (71) to an exterior location. The sweep conveyor assembly has a sweep conveyor (S) for transporting material (74) inside the silo (S) or granary towards the centre of the floor (71) where it can be discharged by the discharge apparatus (1), a holder (H), and a link mechanism (8) for connecting the sweep conveyor (S) to the holder (H), and in turn having a connection link (L) with a first end (83) and a second end (84). The first end (83) is connected to the holder (H) at a fixed pivot point and the sweep conveyor (S) is connected to the second end (84) of the connection link (L) at a movable pivot point.
