PROBLEM TO BE SOLVED: To improve visibility of a reaping front part in a harvesting operation while preventing flying of grains to a driver seat side in a combine harvester in which a raising device for raising grain culms to the front side of the driver seat, and an auxiliary raising device for separating tangling of planted grain culms are arranged.SOLUTION: The combine harvester includes: the grain culms raising device (8) for raising grain culms to the front side of the driver seat (5) and the auxiliary raising device (60) for horizontally separating the grain culms to the front side of the grain culms raising device (8). The the combine harvester includes: a protection cover body (15) for preventing flying of grain culms threshed by the grain culms raising device (8) to the driver seat side (5) by projecting upward of the grain culms raising device (8) is provided and an auxiliary protection cover body (18aL) capable of projecting forward more than the protection cover body (15) and provided at the upper part of the grain culms raising device (8) at the rear side of the auxiliary raising device (60).COPYRIGHT: (C)2012,JPO&INPIT【課題】運転席の前側に穀稈を引き起す引起装置と植立穀稈の絡み合いを分離する補助引起装置が配置されるコンバインにおいて、運転席側への穀粒の飛散を防ぎながら、収穫作業における刈取前部の視認性を向上させる。【解決手段】運転席(5)の前側に穀稈を引き起す穀稈引起装置(8)を設け、該穀稈引起装置(8)の前側に穀稈を左右に分離する補助引起装置(60)を設けたコンバインにおいて、穀稈引起装置(8)の上方へ張り出して該穀稈引起装置(8)によって脱粒した穀粒が運転席(5)側へ飛散するのを防ぐ防護カバー体(15)を設けるとともに、補助引起装置(60)後側の穀稈引起装置(8)の上方の部位に、防護カバー体(15)よりも前方へ張り出し可能な補助防護カバー体(18aL)を設ける。【選択図】図1
