PROBLEM TO BE SOLVED: To provide a combine-harvester enabled to grass-divide grain culm smoothly by reducing the entangling of grain culm on a rotary fulcrum shaft of a grass-dividing member and the vicinity portions of the member.SOLUTION: A grass-dividing frame (10) belonging to a mowing device (4) is equipped in its front part with a grass-dividing member (11) for dividing the grain culm. The grass-dividing frame (10) attached to one transverse side portion of the mowing device (4) is composed of: a first frame (10r) along the longitudinal direction of a running car body (1) and a second frame (10f) having the grass-dividing member (11). The rear end portion of the second frame (10f) is supported transversely rotatably on a rotary fulcrum shaft (17) with respect to the front end of the first frame (10r). To the second frame (10f), there is integrally attached a grain culm guide member (21) for guiding the grain culm divided at said grass-dividing member (11), to the outer side of said rotary fulcrum shaft (17).SELECTED DRAWING: Figure 9COPYRIGHT: (C)2016,JPO&INPIT【課題】分草部材の回動支点軸およびその近傍の部位への穀稈の絡み付きを少なくし、穀稈を円滑に分草できるものとする。【解決手段】刈取装置(4)に備えた分草フレーム(10)の前部に穀稈を分草する分草部材(11)を設け、刈取装置(4)の左右一側部に備えた分草フレーム(10)を、走行車体(1)の前後方向に沿う第1フレーム(10r)と、分草部材(11)を設けた第2フレーム(10f)から構成し、第2フレーム(10f)の後端部を、第1フレーム(10r)の前端部に対して回動支点軸(17)回りに左右回動自在に支持し、第2フレーム(10f)に、前記分草部材(11)で分草された穀稈を前記回動支点軸(17)の外側方へ案内する穀稈案内部材(21)を一体に取り付ける。【選択図】図9
