PROBLEM TO BE SOLVED: To provide a threshing device for a combine-harvester, in which grains to fly out during a threshing operation from a grain culm supply port to the outside of a handling chamber and grains to be shed from the grain culm before they are fed to the inside of a handling chamber are recovered into the threshing device, with a simpler configuration than conventional ones, thereby to reduce a harvesting loss.SOLUTION: In a threshing device for a combine-harvester, a grain culm supply port (27) is opened in a front portion of a handling chamber (16), a recovery port (27R) facing an upper portion of a rocking separation shelf (20) is opened over the front side of a selection chamber (19) disposed on the lower side of the handling chamber (16), a grain guide chute (28) is inclined downward to the recovery port (27R), a sash-shaped grain culm guide (29) for receiving the grain culm to be poured into the grain culm supply port (27) is disposed on the upper side of the grain guide chute (28), and a rear end portion of the grain culm guide (29) is made to face the grain culm supply port (27).COPYRIGHT: (C)2014,JPO&INPIT【課題】コンバインの脱穀装置において、従来よりも簡単な構成で、脱穀中に穀稈供給口から扱室外へ飛び出す穀粒や扱室内へ供給する前に穀稈から脱粒する穀粒を脱穀装置内へ回収して収穫ロスを少なくする。【解決手段】扱室(16)の前部に穀稈供給口(27)を開口し、扱室(16)の下側に備えた選別室(19)の前側上部には、揺動選別棚(20)の上部に臨む回収口(27R)を開口し、該回収口(27R)へ向けて下り傾斜する穀粒案内シュート(28)を設け、該穀粒案内シュート(28)の上側には、穀稈供給口(27)へ投入される穀稈を受ける桟状の穀稈ガイド(29)を設け、該穀稈ガイド(29)の後端部を前記穀稈供給口(27)に臨ませたコンバインの脱穀装置とする。【選択図】図3
