PROBLEM TO BE SOLVED: To provide a threshing device in which a threshing cylinder in a threshing chamber is constituted with a front thresher and a rear thresher which continues to the front thresher and rotates with a higher speed than the front thresher, and threshing objects are smoothly transported to the rear side in the boundary between the front thresher and the rear thresher.SOLUTION: In the threshing device, a threshing cylinder 14 in a threshing chamber 13 is constituted with a front thresher 14a and a rear thresher 14b which continues to the front thresher 14a and rotates with a higher speed than the front thresher 14a, a dust feeding guide 17 is provided to a ceiling of the threshing chamber 13 for guiding transport of threshing objects. The dust feeding guide 17 is continuously held in a promoting state where the dust feeding guide is tilted rear-downward toward the lower side of the rotation direction, and is arranged across the boundary of the front thresher 14a and the rear thresher 14b, so that the dust feeding guide functions as a boundary side guide 27.COPYRIGHT: (C)2014,JPO&INPIT【課題】扱室内の扱胴を、前扱部と、該前扱部に連続して前扱部よりも高速回転する後扱部とによって構成した脱穀装置において、前扱部と後扱部の境界において脱穀物をスムーズに後方搬送できる脱穀装置を提供することを課題としている。【解決手段】扱室13内の扱胴14を、前扱部14aと、該前扱部14aに連続して前扱部14aよりも高速回転する後扱部14bとによって構成し、該扱室13の天井側に脱穀物の搬送をガイドする送塵ガイド17を設けた脱穀装置において、扱胴14の回転方向下手に向かって後方に傾斜させた促進状態で常時保持された送塵ガイド17を、前扱部14aと後扱部14bとの境界を跨ぐように設けることにより、該送塵ガイド17を境界側ガイド27としたことを特徴としている。【選択図】図4
