Abstract
A combined auger conveyor and screening apparatus features an inlet hopper mounted to an auger housing adjacent an inlet end thereof, and a screen support frame disposed atop the inlet hopper and supporting a screen over an area of the inlet hopper. A screen drive mechanism is removably mounted to the auger housing, coupled to the screen support frame and operable to drive oscillatory motion of the screen. An angle adjustment mechanism is operable to vary a position of ground wheels relative to the auger housing in order to change an inclination angle of the auger housing and screen relative to the ground. A hydraulic circuit supplying hydraulic motors for both the auger and the screen drive mechanism comprises a control valve operable to adjust an oscillatory speed of the screen support frame.
