In a vibratory conveyor having a resiliently supported trough for material and two transversely mounted eccentric mass exciter drive assemblies 30, 32. Only one drive assembly is driven at any time to impart a vibratory force to the trough along a straight line path, the improvement being a supporting structure for each drive assembly which rigidly supports the drive assembly relative to the trough in the straight line path and resiliently supports the drive assembly transverse to the straight line path. The supporting structure comprises spaced, planar flexible straps or plates 50 extending transverse to the longitudinal axis of the trough and parallel to the plane containing the motor centre line and the trough center of gravity. The straps are rigid in the direction of movement of the trough and flexible in the direction transverse thereto. In an alternative embodiment each vibratory apparatus is pivotally connected to the trough and a portion of the motor remote from the pivot is suspended from the trough by a coil spring directed transverse to the straight line path. <IMAGE> |
