ABSTRACT:
In a grader device grain is fed down a slide which ejects the grain outwardly and forwardly into an airstream. The slide is provided by a resilient flexible sheet, the contour and inclination of which is adjusted by a plurality of support rods against which the sheet presses and the positions of which are adjustable. A plurality of transverse collecting troughs with adjustable baffles, receive the separated grains according to the weight thereof with the top quality grain being heaviest, collecting in the forward trough. A suction fan extracts dust before it reaches the main airstream and diverts it into a cyclone or the like. Accurate airstream control is achieved by a plurality of adjustable wind boards strategically situated within the grader device. An even dispersal device receives the grain from a storage facility and ensures even distribution of the various weights of grain, straw and chaff prior to it being fed to a hopper which delivers the grain to the slide thus avoiding the undesirable side separation in the hopper which occurs when a relatively large quantity of grain flows into and through a hopper.
