Vibratory material handling equipment suspension systems. The problem with conventional vibrating devices for driving work members is that they lack adjustability and are very complex. The solution is to design a torsional vibrating device (10) for operation as a two mass vibrating system consisting of a first mass having a generally circular work member (22) and a spring mechanism (12) connecting the first mass to the second mass (27) excited by a motor driven eccentric weight or weights (14) so that the second mass (27) vibrates in a circular path having a circular component and a vertical component which will cause material on said work member (22) to be conveyed in a circular direction. The spring member (12) is unique in this combination. The entire system is isolated from a support structure (20). This system has application for controlling the flow of bulk material from a hopper (16), screen (123) or feeder (222) or for elevating or lowering a material in a helical trough (323) or for orientation of discrete particles (322) or other applications depending on a properly designed work member. |
