Abstract
Disclosed herein is an elliptical motion drive device for use in a step screen. The elliptical motion drive device comprises first and second eccentric wheels coupled to a single drive shaft to be eccentrically positioned to each other. Upon rotation of the drive shaft, the first and second eccentric wheels rotate and move along guide rails formed in different directions from each other to transversely and longitudinally rotate movable lattice plates connected to a movable frame of the step screen, thereby achieving elliptical motion of the movable lattice plates.
