PROBLEM TO BE SOLVED: To make efficient the discharging work of cereal grains in a combine harvester equipped with a cereal grain tank for storing selected cereal grains and a discharging auger for discharging the cereal grains in the cereal grain tank to the outside of a machine.SOLUTION: The combine harvester is constituted by installing a discharge-covering body (14) for covering the lower side surroundings of a discharging port (12) formed at the tip end part of the discharging auger (11), guiding the cereal grains delivered from the discharging port (12) to a lower direction by the discharge-covering body (14), also installing a guiding plate (15) for guiding the cereal grains along the inside of the tip end side lateral wall (F) of the discharge-covering body (14) and making the lower part of the guiding plate (15) capable of leaving and rotating from the tip end side lateral wall (F) by using its upper end part as a fulcrum (16) so as to be able to change the discharging direction of the cereal grains to an auger base part side by changing the rotary position of the guiding plate (15).COPYRIGHT: (C)2011,JPO&INPIT【課題】選別した穀粒を貯留する穀粒タンクと、該穀粒タンク内の穀粒を機外に排出する排出オーガとを備えたコンバインにおいて、穀粒の排出作業を合理化する。【解決手段】排出オーガ（１１）の先端部に形成された排出口（１２）の下側周囲を覆う排出カバー体（１４）を設け、該排出カバー体（１４）により排出口（１２）から出る穀粒を下方へガイドすると共に、排出カバー体（１４）の先端側側壁（Ｆ）の内側に沿って穀粒を案内するガイド板（１５）を設け、該ガイド板（１５）をその上端部を支点（１６）として下部を先端側側壁（Ｆ）から離間回動可能とし、該ガイド板（１５）の回動位置を変更することにより、穀粒の排出方向をオーガ基部側に変更できるように構成した。【選択図】図５
