PROBLEM TO BE SOLVED: To provide a reaping unit of a combine harvester which easily removes clogged grain culms without requiring a troublesome operation in conveying abnormality such as clogging of reaped grain culms in an internal conveying path of the reaping unit.SOLUTION: The reaping unit of the combine harvester includes a plurality of raising mechanisms (11), an upper transmission frame (12) for pivotally supporting the raising mechanisms (11) so as to perform front development, a raking mechanism (21) for raking grain culms and a clamping and conveying mechanism (22) for sending the grain culms backward. The raking mechanism (21) and the clamping and conveying mechanism (22) are equipped with a linkage and separation means that movably supports a conveying member at an inside position, which is held between two conveying lines of mutually adjacent positions, as an integrated movable inside body (23) separably from a conveying member at an outside position and separates the movable inside body (23) in association with the forward development operation of the upper transmission frame (12).COPYRIGHT: (C)2012,JPO&INPIT【課題】刈取装置の内部搬送経路における刈取穀稈の詰まり等の搬送異常の際に、煩わしい操作を要することなく、詰まった穀稈を容易に除去することができるコンバインの刈取装置を提供する。【解決手段】コンバインの刈取装置は、複数の引起機構(11)と、これら引起機構(11)を前方展開可能に軸支する上部伝動フレーム(12)と、穀稈を掻込む掻込機構(21)と、その穀稈を後方に送出する挟持搬送機構(22)とを備えて構成され、上記掻込機構(21)と挟持搬送機構(22)は、相互隣接位置の2つの搬送線によって挟まれる内側位置の搬送部材を一体の可動内側体(23)として外側位置の搬送部材から分離可能に可動支持するとともに、この可動内側体(23)を上記上部伝動フレーム(12)の前方展開動作と連動して分離動作させる連係分離手段を設けたものである。【選択図】図4
