PROBLEM TO BE SOLVED: To provide a combine harvester having a stalk introduction width increased in association with the sliding of a harvesting unit to a harvested side, and increasing the number of rows of stalks to be harvested.SOLUTION: A frame (2) including a traveling unit (3) is mounted with a threshing unit (15) including a threshing cylinder (69) and a chaff discharging cylinder (71). The frame includes: a harvesting slide mechanism (131) for horizontally sliding a harvesting unit (6) disposed in front of the threshing unit (15), relative to the frame (2) and an association mechanism for turning a divider (7R) provided at the right end of the harvesting unit (6) to the right side in association with the rightward sliding of the harvesting unit (6). The divider at the right end is opened in association with the sliding of the harvesting unit to a harvested side, the stalk introduction width of the harvesting unit is increased, and the rows of stalks to be harvested is increased.COPYRIGHT: (C)2012,JPO&INPIT【課題】刈取装置の既刈側へのスライドに連動して穀稈導入幅を拡大し、収穫する穀稈の条数を増加させる。【解決手段】走行装置(3)を備えたフレーム(2)に扱胴(69)と排塵処理胴(71)を備えた脱穀装置(15)を搭載し、脱穀装置(15)の前方に配置した刈取装置(6)を前記フレーム(2)に対して左右方向へスライドさせる刈取スライド機構(131)を設け、刈取装置(6)の右側へのスライドに連動して刈取装置(6)の右端部に備えた分草具(7R)を右側へ回動させる連動機構を設け、刈取装置の既刈側へのスライドに連動して右端部の分草具を開き、刈取装置の穀稈導入幅を拡大して、収穫する穀稈の条数を増加させる構成とする。【選択図】図8
