COMBINE APPARATUS

The invention is a combine apparatus for harvesting field crops comprising in combination a vehicular supporting frame, means mounted on the frame for severing and disjoining the stalk and fruit portions of a field crop and producing a discharge thereof. Rotatably mounted on the supporting frame are a plurality of concentrically disposed, hollow cylindrical drums having foraminous walls which define a plurality of chambers. The innermost chamber is positioned to receive the discharge from the threshing means and the openings in the foraminous walls are graduated to pass the fruit portions, grain portions, and refuse material of the crop, respectively, and to retain the stem, tailings, and grain portions of the crop, respectively. Within each of the chambers there are provided auger means for forcibly moving the grain axially therethrough.
