Machine for clearing bulk material

摘要

This disclosure relates to a machine for clearing bulk material from a bin table by moving therealong a movable support carrying a pivotally mounted rotatable clearing wheel including a first drive mechanism for moving the movable support and a second drive mechanism for rotating the clearing wheel and a control mechanism responsive to operational conditions of the second drive mechanism for controlling the operation of the first drive mechanism whereby the rotational speed of the clearing wheel may be increased or decreased as might be the speed of the movable support in dependence upon the resistance of the bulk material being offered to the clearing wheel during the rotation of the latter.
