ABSTRACT:
A material handling system is provided having a plurality of separately actuatable flow gates disposed between the storage bin and the unloading conveyor which are sequentially opened and closed by a sliding zipper-type cam member to carefully control the amount of material applied to the conveyor. A compact screw drive assembly is mounted within a hollow of the screw at one end and enables the screw to be initially operable at a low speed to provide a higher break away torque when starting the screw and to be then operable at a higher speed and lower torque during constant running of the screw. The drive assembly includes a reversible motor coupled to a speed reducing gear arrangement in the reverse direction such that the motor is run in reverse when starting the screw and then run in forward during constant running of the screw.
