PROBLEM TO BE SOLVED: To provide a reaping implement for a combine harvester which is capable of conducting its own maintenance in a short time, and capable of preventing the raising times of raisers from being broken in the upward turning of the raisers, and capable of engaging the input shaft and output shaft of each of the raisers with each other in a short time in downward turning of the raisers.SOLUTION: The reaping implement for a combine harvester has the following construction: the upper part of the support arm (81) of a second raiser (80) is attached to a transverse shaft (60) a detachment gear (91) pivoted on a detachment transmission shaft (90) is provided on a site on the support arm (81) side standing against the movable gear (42) of an upper transmission shaft (41) pivoted on the gear case (40) on the top of a raising transmission cylinder (30) by the extending operation of an extendable/retractable implement (65), the second raiser (80) undergoes downward turning around the transverse shaft (60) to engage the mobile gear (42) and the detachment gear (91) with each other and by the retracting operation of the implement (65), the second raiser (80) undergoes upward turning around the transverse shaft (60) to disengage the mobile gear (42) and the detachment gear (91) from each other.COPYRIGHT: (C)2012,JPO&INPIT【課題】刈取装置のメンテナンスを短時間で行え、引起装置の上昇回動時の引起爪の破損を防止し、引起装置の下降回動時の入力軸と出力軸の噛み合わせを短時間に行う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】第2引起装置(80)の支持アーム(81)の上方部を横軸(60)に取付け、引起伝動筒(30)上部のギヤケース(40)に軸支された上部伝動軸(41)の可動ギヤ(42)と対向する支持アーム(81)側の部位に、離脱伝動軸(90)に軸支した離脱ギヤ(91)を設け、伸縮具(65)の伸長作動によって、第2引起装置(80)が横軸(60)を中心に下降回動して可動ギヤ(42)と離脱ギヤ(91)が噛み合い、伸縮具(65)の縮短作動によって、第2引起装置(80)が横軸(60)を中心に上昇回動して可動ギヤ(42)と離脱ギヤ(91)の噛み合いが外れる構成により解決される。【選択図】図1
