PROBLEM TO BE SOLVED: To avoid clogging in a grain culm conveying device of a combine due to disturbance in the conveyed attitude of grain culms, thereby smoothing the conveyance of grain culms.SOLUTION: An auxiliary conveying chain (69) for delivering grain culms from a supply chain (22) to a feed chain (21) is disposed in a position deviating from the feed chain (21) toward the ear side of the grain culms conveyed. The auxiliary conveying chain (69) is driven at a speed synchronized with the driving speed of a reaping device (5). A rotor (36) that is driven by and in association with the auxiliary conveying chain (69) is made to face the front side of the conveyance starting end portion of the feed chain (21).COPYRIGHT: (C)2014,JPO&INPIT【課題】本発明は、コンバインの穀稈供給装置において、穀稈の搬送姿勢の乱れによる詰まりの発生を抑制し、穀稈の搬送を円滑化することを課題とする。【解決手段】フィードチェン(21)に対して搬送穀稈の穂先側に偏倚した部位に、供給チェン(22)からフィードチェン(21)へ穀稈を受け渡す補助搬送チェン(69)を配置し、補助搬送チェン(69)を刈取装置(5)の駆動速度に同調した速度で駆動する構成とし、補助搬送チェン(69)から連動して駆動される回転体(36)を、フィードチェン(21)の搬送始端部の前側に臨ませする。【選択図】図6
