Conveyor assembly

A conveyor assembly comprising a main conveyor, a boom conveyor unit comprising an elongate support structure and a conveyor mounted in said support structure, a mounting pivotally connected at the discharge end of said main conveyor for movement about a transverse axis relative to said main conveyor, a rotatable support on said mounting to which said boom conveyor unit is mounted for movement in a lateral plane, and a linkage adapted to synchronously alter the position of the mounting relative to the main conveyor on alteration of the angle of inclination thereof, said linkage comprising an upright support member having one end connected to a part of the main conveyor which does not vary in height off the ground, and having its other end pivotally connected to a first link, said first link being angularly disposed relative to said upright support member in a direction towards the discharge end of the main conveyor, and pivotally connected at its other (forward) end to a location on the main conveyor which varies in height on alteration of the inclination of the main conveyor, a bell crank arm mounted on said location of variable height and having a fixed position relative to the first link, and a connecting rod pivotally connected to the bell crank in the mounting.
