PROBLEM TO BE SOLVED: To provide the function of cleaning matter clinging to a movable sieve.SOLUTION: A rocking sorting shelf that performs sorting while transferring by rocking in response to the subject of threshing leaking down from a threshing chamber is provided. The rocking sorting shelf is provided with a movable sieve 24 comprising a plurality of movable sieve members 24b arranged in parallel in their longitudinal direction, the plurality of movable sieve members 24b extending horizontally and being adjustable in longitudinal inclination angle. A cleaning piece 101 for scraping off any matter clinging to the movable sieve members 24b is attached to each movable sieve member 24b in such a manner as to be capable of reciprocating movement in the horizontal direction. The cleaning pieces 101 of the movable sieve members 24b are interconnected by a connection member 102 so that the cleaning members 101 of the movable sieve members 24b are driven to integrally reciprocate in the horizontal direction. While maintained in a connected state to the connection member 102, the cleaning pieces 101 vary in inclination angle integrally with the movable sieve members 24b.COPYRIGHT: (C)2012,JPO&INPIT【課題】可動シーブにおける付着物の清掃機能を提供する。【解決手段】扱室から漏下する脱穀処理物を受けて揺動により移送しつつ選別を行う揺動選別棚を設け、この揺動選別棚に左右方向に延在するとともに前後方向に対する傾斜角度が調整自在の複数の可動シーブ部材24bが前後方向に平行に並設されてなる可動シーブ24を備える。各可動シーブ部材24bに可動シーブ部材24bの付着物を掻き取る清掃片101を左右方向に往復移動可能に付設し、各可動シーブ部材24bの清掃片101を連結部材102により相互に連結して、各可動シーブ部材24bの清掃片101を一体的に左右方向に往復駆動させる構成とし、各清掃片101が連結部材102に対する連結状態を維持しつつ可動シーブ部材24bと一体的に傾斜角度が変化する構成とする。【選択図】図14
