PROBLEM TO BE SOLVED: To provide a combine harvester in which a power transmission mechanism is constructed efficiently to increase productivity and maintainability.SOLUTION: A harvesting power transmission member 68 for transmitting the power of a transmission T to a harvesting unit 7 is wound between a PTO output pulley 67 installed on a PTO output shaft 66 of the transmission T and a harvesting input pulley installed on a harvesting input shaft of the harvesting unit 7. A threshing power transmission member 71 for transmitting the power of an engine E to a threshing unit 5 is wound between an engine output pulley 62 installed on an output shaft 61 of the engine E and a threshing input pulley installed on a threshing input shaft of the threshing unit 5. The engine output pulley 62 is positioned below the threshing power transmission member 68. Guide members 74, 74 surrounding the engine output pulley 62 and guiding the rotary drive of the threshing power transmission member 71 with their inside portions have their outside portions used also as guide members for supporting the threshing power transmission member 68.COPYRIGHT: (C)2014,JPO&INPIT【課題】動力伝達機構を効率的に構成し、生産性やメンテナンス性を向上させたコンバインを提供する。【解決手段】トランスミッションTの動力を刈取部7に伝達する刈取動力伝達部材68を、トランスミッションTのPTO出力軸66に設置したPTO出力プーリ67と、刈取部7の刈取入力軸に設置した刈取入力プーリとの間に巻回するとともに、エンジンEの動力を脱穀部5に伝達する脱穀動力伝達部材71を、エンジンEの出力軸61に設置したエンジン出力プーリ62と、脱穀部5の脱穀入力軸に設置した脱穀入力プーリとの間に巻回し、刈取動力伝達部材68の下方には、エンジン出力プーリ62を配置し、エンジン出力プーリ62を包囲して、内側部で脱穀動力伝達部材71の回転駆動をガイドするガイド部材74,74´の外側部を、刈取動力伝達部材68を支持するガイド部材に兼用した。【選択図】図10
