PROBLEM TO BE SOLVED: To provide a combine harvester, in which a transportation cylinder of a simple construction for lifting and feeding grains can be changed into long specifications by adding minimum members.SOLUTION: A combine harvester is enabled to perform a harvesting travel, and comprises: a grain storing device (1) for storing harvested grains threshed a relay member (7) for transmitting a grain lifting power in a manner to incline transversely of an elevating axial line while raising and guiding the grains from the grain feeding exit of the grain storing device (1) and a transfer cylinder (6) for feeding out the lifted grains by a grain-lifting helical axis (35) receiving the grain lifting power via the relay member (7). Between the relay member (7) and the transfer cylinder (6), there are provided an extension cylinder (101) for guiding the grains and an elongated helical axis (102) for lifting the grains while transmitting to the grain-lifting helical axis (35), so that the transfer cylinder (6) can be elongated.COPYRIGHT: (C)2016,JPO&INPIT【課題】揚穀送出用の簡易構成の搬送筒について、最小限の部材追加で長尺仕様に切替えを可能とするコンバインを提供する。【解決手段】コンバインは、脱穀された収穫穀物を収容する穀粒貯留装置(1)と、この穀粒貯留装置(1)の穀粒送出口から穀粒を上昇案内しつつその上昇軸線を左右方向に傾斜可能に揚穀動力を伝動する中継部材(7)と、この中継部材(7)を介して揚穀動力を受ける揚穀螺旋軸(35)によって揚穀送出する搬送筒(6)とを備えて収穫走行可能に構成され、上記中継部材(7)と上記搬送筒(6)との間に、穀粒を案内する延長筒(101)と、上記揚穀螺旋軸(35)に伝動しつつ揚穀する延長螺旋軸(102)とを設けることにより、搬送筒(6)の長尺化を可能とするものである。【選択図】図21
