PROBLEM TO BE SOLVED: To solve the problem of an insufficient rigidity of a harvesting support structure and instability of harvesting operations.SOLUTION: In a harvesting frame 20 of a harvesting implement 6 of a combine harvester, a right-left lower lateral transmission case 21 is attached to the front end of the harvesting frame 20 the base part of which is turnably attached to the machine side. A lateral transmission case 27 is provided on one side of the right and left of the lower lateral transmission case 21, and a lateral frame 28 is provided on the other side of the right and left of the lower lateral transmission case 21. Between upper ends of the lateral transmission case 27 and the lateral frame 28, there is provided the upper lateral transmission case 29. Between a vertical-direction intermediate part of the lateral frame 28 and a front/rear-direction intermediate part or front end part of a thresher 35, there is provided a front/rear-direction lateral reinforcing side frame 40.COPYRIGHT: (C)2011,JPO&INPIT【課題】刈取支持構成の剛性不足、刈取作業の不安定化。【解決手段】コンバインの刈取装置6の刈取フレーム20は、基部を機体側に回動自在に取付けた刈取フレーム20の先端に左右方向の下部横伝動ケース21を取付ける。下部横伝動ケース21の左右一方側に側部伝動ケース27を設け、下部横伝動ケース21の左右他方側に側部フレーム28を設ける。側部伝動ケース27と側部フレーム28の上端部間に上部横伝動ケース29を設ける。側部フレーム28の上下方向中間部と分草杆35の前後方向中間部または前端部との間に、前後方向の側部補強横フレーム40を設ける。【選択図】図4
