PROBLEM TO BE SOLVED: To enlarge the filtration part of the receiving net of a treating chamber from the width of a shaking separation shelf below a threshing chamber to an external part, to enhance the filtration ability of the threshing chamber and to improve threshing treatment ability.SOLUTION: The threshing treatment apparatus is equipped with a first filtration route (22) for pivotally mounting a dust discharging treatment cylinder (17) for receiving a discharge dust material from the threshing chamber (3) and treating the discharge dust material while transporting it in the axial direction in a dust discharging treatment chamber (18) and directly introducing the treatment material treated in the dust discharging treatment chamber (18) onto a lower shaking separation shelf (40), and a second separation route (26) for introducing the treatment material treated in the dust discharging treatment chamber (18) onto the shaking separation shelf (40) by bypassing the outside of the side end part of the shaking separation shelf (40).COPYRIGHT: (C)2008,JPO&INPIT【課題】 扱室下方の揺動選別棚幅より外方部まで処理室受網の濾過部を拡大し、処理室の濾過能力を高め、脱穀処理能力の向上を図る。【解決手段】 扱室(3)からの排塵物を受け入れて軸芯方向に移送しながら処理する排塵処理胴(17)を排塵処理室(18)内に軸架し、この排塵処理室(18)内で処理された被処理物を下方の揺動選別棚(40)上に直接導く第1濾過経路(22)と、この排塵処理室(18)内で処理された被処理物を揺動選別棚(40)の側端部よりも外方を迂回して揺動選別棚(40)上に導く第2濾過経路(26)とを設ける。【選択図】 図5
