Abstract
A compact mobile variable angle vibrating screen with an overhead feed conveyor drive system configured to accommodate nesting into the feedbox of the vibrating screen by use of a 90-degree input shaft speed reducer; a V-belt drive and a drive shaft coupling the two and a motor mounted in front of and perpendicular to the head pulley of the feed conveyor, all arranged in a configuration to nest within a feed box of the vibrating screen and to minimize the need for offset feeding with the conveyor.
Claims11
A variable slope vibrating screen system for material processing comprising:
- a vibrating screen, having a feedbox,
- an overhead conveyor with a conveyor longitudinal axis and a discharge end, the overhead conveyor, disposed above said vibrating screen, and configured to nest for transport within said feedbox;
- said overhead conveyor further comprising a drive system comprising:
- a speed reducer mounted to one side of said overhead conveyor and coupled to a head pulley of said overhead conveyor where said head pulley is a pulley around which a material supporting surface turns when said overhead conveyor transports, on said material supporting surface, material to be processed by said vibrating screen;
- a drive shaft coupled to said speed reducer, said drive shaft having a shaft longitudinal axis which is parallel with said conveyor longitudinal axis;
- a transverse drive oriented parallel to the head pulley extending across to an opposing side of the conveyor from the speed reducer;
- and
- a motor, oriented perpendicular to the head pulley and coupled to said transverse drive, for providing drive power to the drive system and the overhead conveyor.

A vibrating screen system comprising:
- a vibrating screen;
- an overhead conveyor disposed above said vibrating screen, and configured to nest within said vibrating screen;
- said overhead conveyor having a discharge opening;
- and
- means for driving said overhead conveyor which is partially disposed in front of said discharge opening;
- wherein said means for driving comprises a motor mounted perpendicular to a head pulley at the discharge end of said overhead conveyor;
- where said head pulley is a pulley around which a material supporting surface turns when said overhead conveyor transports, on said material supporting surface, material to be processed by said vibrating screen;
- wherein said means for driving comprises a speed reducer mounted to said head pulley and the speed reducer is mounted on a side of the overhead conveyor which is opposite a side of the overhead conveyor which is proximal to the motor.
