PROBLEM TO BE SOLVED: To provide a threshing apparatus so designed that: apart from the main winnower, a second winnower is installed to increase the ability of wind-powered separation on a swing separatory shelf, especially enable a secondary treated product to be integrally separated, thus improve separatory performance.SOLUTION: The threshing apparatus is so designed that: a first winnower (14) is installed on the lower front side of a swing separatory shelf (8) receiving a threshed product from a threshing chamber (3) and subjecting the threshed product to sieve separation while putting it to rearward swing conveyance a secondary treatment mechanism (18) returning a secondary treated product onto the swing separatory shelf (8) via one of the left and right sides thereof is installed and a secondary winnower (25) making airblowing along the top surface of the swing separatory shelf (8) via the front thereof is installed, wherein the secondary winnower (25) is biasedly installed so that a separatory wind goes through along the secondary treatment mechanism (18) side.COPYRIGHT: (C)2013,JPO&INPIT【課題】 主唐箕とは別に第2唐箕を設置することによって揺動選別棚上での風選能力を高め、特に2番処理物の集中選別を可能とし、選別性能の向上を図る。【解決手段】 扱室(3)からの脱穀処理物を受け入れて後方に揺動移送しながら篩い選別する揺動選別棚(8)の下方前部側に第1唐箕(14)を設け、揺動選別棚(8)の左右一側から該揺動選別棚(8)上へ2番処理物を還元する2番処理装置(18)を装備し、揺動選別棚(8)の前方から該揺動選別棚(8)の上面に沿って送風する第2唐箕(25)を設け、この第2唐箕(25)は選別風が2番処理装置(18)側に沿って通過するように偏倚させて配置する。【選択図】 図1
