PROBLEM TO BE SOLVED: To provide a combine harvester that comprises two right and left sets of cutting blades composed of stationary blades and movable blades, avoids clogging between the sliding right and left movable blades and maintains excellent cutting performance.SOLUTION: The combine harvester comprises two sets of reaping blades 31 composed of the stationary blades 33 having a large number of teeth disposed in parallel in the right and left directions between right and left outside separation frames 24 and the movable blades 34 that are arranged on the stationary blades 33 and have a large number of teeth disposed in parallel and sliding in the right and left directions relatively to the stationary blades 33. A cover member 35 extending from near blade roots to blade tips of the right and left movable blades 34 is arranged at the upper position of the movable blade 34 between the right and left movable blades 34.COPYRIGHT: (C)2010,JPO&INPIT【課題】固定刃と可動刃からなる刈刃を左右二組備え、摺動する左右の可動刃間の詰まりを回避するとともに、良好な切断性能を維持することのできるコンバインを提供することにある。【解決手段】左右外側の分草フレーム24の間に、左右方向に多数の歯を並設した固定刃33と、固定刃33の上に配置され、固定刃33に対して左右方向に摺動する多数の歯を並設した可動刃34とからなる刈刃31を左右に二組備えたコンバインであって、左右の可動刃34の間における可動刃34の上位の位置に、左右の可動刃34の略刃元から刃先に亘るカバー部材35を配設してある。【選択図】図5
