PROBLEM TO BE SOLVED: To provide a combine harvester capable of carrying reaped grains-with-stems to be in threshing posture such that their tips of ears go ahead a little of their stump parts, even the action speed of a grain-with-stem raising-up device 223 is changed relating to the properties and the like of unreaped grain planted and standing in the field, thereby being made able to improve the carrying performance of a grain-with-stem carrying means 34.SOLUTION: The combine harvester provided with a travelling machine body 1 equipped with a travelling part 2 actuated by an engine 14, the grain-with-stem raising-up device 223 taking in grains-with-stems planted and standing in the field, a reaping blade device 222 for cutting the stump parts of the grains-with-stems planted and standing in the field, and the grain-with-stem carrying means 34 for nipping and carrying the grains-with-stems, of which stump parts have been cut by the reaping blade device 222 is constituted by being provided with an electric motor 92 for longitudinal carrying drive for actuating the grain-with-stem carrying means 34 and a raising-up speed sensor 291 for detecting the actuation speed of the grain-with-stem raising-up device 223, so as to change and control the rotary speed of the electric motor 92 for longitudinal carrying drive, based on the detection result of the raising-up speed sensor 291.COPYRIGHT: (C)2009,JPO&INPIT【課題】圃場に植立した未刈り穀稈の性状等に関連して穀稈引起装置223の作動速度が変更されても、刈取り穀稈の穂先側が株元よりも若干先行した脱穀姿勢になるように刈取り穀稈を搬送でき、穀稈搬送手段34の搬送性能を向上できるようにしたコンバインを提供するものである。【解決手段】エンジン14によって作動する走行部2を備えた走行機体1と、圃場に植立した穀稈を取込む穀稈引起装置223と、圃場に植立した穀稈の株元を切断する刈刃装置222と、前記刈刃装置222によって株元が切断された前記穀稈を挟持搬送する穀稈搬送手段34とを備えてなるコンバインにおいて、前記穀稈搬送手段34を作動する縦搬送駆動用電動モータ92と、前記穀稈引起装置223の作動速度を検出する引起し速度センサ291とを設け、前記引起し速度センサ291の検出結果に基づき、縦搬送駆動用電動モータ92の回転速度を変更制御するように構成したものである。【選択図】図7
