PROBLEM TO BE SOLVED: To improve efficiency in threshing work by enhancing filtering capability in a discharged dust processing chamber.SOLUTION: The thresher includes: a first filtering pathway (22) for directly guiding processed products taken into the discharged dust processing chamber (18) onto a swinging sorting shelf (40) below and a second filtering pathway (26) having a guide plate (29) taking a detour outside of a side end of the swinging sorting shelf (40) below for guiding the processed products processed within the discharged dust processing chamber (18) onto the swinging sorting shelf (40). A receiving net disposed in the discharged dust processing chamber (18) is formed of a first receiving net (24) facing the inner surface of a discharged dust processing drum (17) and a second receiving net (28) facing the lower part of the discharged dust processing barrel (17). The second receiving net (28) has a resistor body (31) for applying resistance to the transfer of the processed products within the discharged dust processing chamber (18) to make the processed products leaking from the second receiving net (28) flow onto the swinging sorting shelf (40) by a guide plate (29).COPYRIGHT: (C)2012,JPO&INPIT【課題】排塵処理室における濾過能力を高め、脱穀処理作業の能率を向上させる。【解決手段】排塵処理室(18)内に取込まれて処理された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、排塵処理室(18)内で処理された処理物を下方の揺動選別棚(40)の側端部よりも外方を迂回して揺動選別棚(40)上に流下案内する案内板(29)を有した第2濾過経路(26)を備え、排塵処理室(18)に備える受網を、排塵処理胴(17)の内側面部に臨む第1受網(24)と、排塵処理胴(17)の下部に臨む第2受網(28)から形成し、第2受網(28)には排塵処理室(18)内の処理物の移送に抵抗を付与する抵抗体(31)を備えて、第2受網(28)から漏下した処理物を案内板(29)によって揺動選別棚(40)上へ流下させる構成とする。【選択図】図5
