<p>The problem addressed by the invention of the present application is, in a normal-type combine, to achieve both increased threshing efficiency and decreased cost resulting from a simplified structure. The normal-type combine is provided with: a harvesting device (3) that has a cutting blade (15); and a threshing device (9) that has a threshing drum (21). Harvested grain stalks are supplied from the harvesting device (3) to the threshing device (9) via a feed house (11). The threshing drum (21) has: a plurality of polygonal-cross-section frames (145) that extend in parallel to a threshing drum shaft (20) and that are arranged in the peripheral direction of the threshing drum (21); and numerous rod-shaped comb teeth (146) that are provided protruding outwards from the frames (145). Each frame (145) is supported by the threshing drum shaft (20) with a support body (140) therebetween.</p> |
