PROBLEM TO BE SOLVED: To continue harvesting operation only by slightly reducing a reaping speed, even when the driving load of a horizontal reaping blade device is increased, by changing driving force transmitting mechanisms of the horizontal reaping blade device and a vertical reaping blade device to lightly drive the vertical reaping blade device.SOLUTION: The reaping device for multipurpose type combine harvester includes: a horizontal reaping blade device (16) having a horizontal attitude for reaping planted crops a scraping reel (18) for scraping the planted crops at a position above the horizontal reaping blade device (16) and a vertical reaping blade device (5) for vertically cutting and separating the planted crops provided at a lateral end position in a reaping action area of the horizontal reaping blade device (16). The reaping device further includes a reaping blade driving case (7) which relays driving force of an engine, and an output shaft (26) provided on the reaping blade driving case (7) includes a horizontal drive-side arm (8a) for driving a movable horizontal reaping blade (4) of the horizontal reaping device (16) and a vertical drive-side arm (8b) for driving a movable vertical reaping blade (2) of the vertical reaping blade device (5).COPYRIGHT: (C)2013,JPO&INPIT【課題】横刈刃装置と縦刈刃装置の駆動力伝動機構を変更することで、横刈刃装置の駆動負荷が増加しても縦刈刃装置が軽快に駆動されるものとし、刈取速度を僅かに低下することで収穫作業を継続出来るようにする。【解決手段】植立作物を刈り取る横向き姿勢の横刈刃装置(16)と、横刈刃装置(16)の上方位置で植立作物を掻き込む掻込みリール(18)とを備え、横刈刃装置(16)の刈取作用域における横側端部位置に、植立作物を縦方向に切断して分離する縦刈刃装置(5)を設けた汎用型コンバインの刈取装置において、エンジンの駆動力を中継する刈刃駆動ケース(7)を設け、この刈刃駆動ケース(7)に設けた出力軸(26)に、横刈刃装置(16)の可動横刈刃(4)を駆動する横駆動側アーム(8a)と、縦刈刃装置(5)の可動縦刈刃(2)を駆動する縦駆動側アーム(8b)を設ける。【選択図】図2
