PROBLEM TO BE SOLVED: To stabilize the supporting constitution by arranging an input shaft as a power transmission route to waste straw transporting devices in a space above a treating cylinder, effectively utilizing the existing space and supporting a bevel gear case interposed between an input shaft and a transmission shaft to the waste straw transporting devices on a rear side plate of a threshing chamber.SOLUTION: A thresher is provided as follows: The waste straw transporting devices (14) for performing a carrying out treatment of waste straws after performing a threshing treatment toward the rear side are arranged at the rear of the threshing chamber (8), and the input shaft (17) to the waste straw transporting devices (14) is installed in an upper position of the treating cylinder (12). The thresher is composed so as to rotate and drive the waste straw transporting devices (14) from the input shaft (17) through a bevel gear case (19) internally installing a bevel gear mechanism (18) supported on the rear side plate (27) of the threshing chamber and the transmission shaft (21) extended from the bevel gear case (19) obliquely rearward.COPYRIGHT: (C)2008,JPO&INPIT【課題】 本発明の課題は、排藁搬送装置への動力伝達経路として入力軸を処理胴の上方空間部に配置して既存空間を有効利用し、入力軸から排藁搬送装置への伝動軸との間に介在するベベルギヤケースを扱室の後側板に支持することによって支持構成の安定化を図ることにある。【解決手段】扱室(8)の後方に脱穀処理後の排藁を後方に向けて搬出処理する排藁搬送装置(14)を配設し、前記処理胴(12)の上方位置には該排藁搬送装置(14)への入力軸(17)を架設し、この入力軸(17)から扱室の後側板(27)に支持させたベベルギヤ機構(18)を内装するベベルギヤケース(19)とこれより斜め後方に延出する伝動軸(21)を介して排藁搬送装置(14)を回転駆動すべく構成する。【選択図】 図4
