摘要： A rotating solid cylinder is used with a complementary concave in a combine to separate grain from the leafy portion of the plant. The solid cylinder has a plurality of raspbars spaced about its periphery and extending the length thereof, while the fixed concave similarly has a plurality of spaced, lengthwise bars in spaced relation from the raspbars of the cylinder as it rotates. The raspbars are positioned outward from and parallel to the convex surface of the cylinder such that the cylinder assembly has a generally star-shaped cross section with the raspbars located at the tips of the star. A curved filler plate coupled to each of the raspbars substantially fills in the gap between adjacent raspbars. The increased mass and inertia of the solid cylinder requires less power to maintain its rotation and allows the cylinder to be rotated more slowly resulting in less damage to the grain. The cylinder's solid structure also prevents soil and debris from entering the cylinder in avoiding out of balance operation of the cylinder, while the curved filler plates provide improved grain engagement and displacement thus increasing the combine's grain handling capacity. In another embodiment, the cylinder is comprised of a plurality of star-shaped hubs in spaced relation along its length and further includes a plurality of raspbars disposed about and mounted to each hub at the tips of each of the stars with a filler plate disposed between adjacent raspbars.
