PROBLEM TO BE SOLVED: To improve efficiency of threshing operation by preventing clogging of a threshed material on an oscillation sorting shelf.SOLUTION: A plurality of sieves (26) of the oscillation sorting shelf (15) for receiving, oscillating and sorting the threshed material from a threshing chamber (11) includes a plurality of cleaning devices (30) comprising vertical cleaning plates (28) arranged with a predetermined interval in a horizontal direction with an attitude in a back and forth direction, and a scraper (29) for removing deposits by making sliding contact with an upper surface of each sieve (26). The plurality of cleaning devices (30) are integrally reciprocated in the horizontal direction. Further, in the scrapers (29), inclined edges (29a, 29a) inclined at a predetermined angle with respect to a moving direction are projected from the cleaning plates (28) in the horizontal direction, and inclined edges (29a, 29a) are caused to make sliding contact with the upper surface of each sieve (26).COPYRIGHT: (C)2012,JPO&INPIT【課題】揺動選別棚上での脱穀処理物の詰まりを防止して脱穀作業の能率を高める。【解決手段】扱室(11)からの脱穀処理物を受け入れて揺動選別する揺動選別棚(15)の複数のシーブ(26)に、前後方向に沿う姿勢で、且つ左右方向に所定間隔を置いて配置した縦姿勢の清掃プレート(28)と、各シーブ(26)の上面に摺接して付着物を除去するスクレーパ(29)とからなる複数の清掃具(30)を備え、これら複数の清掃具(30)を一体的に左右方向へ往復移動可能な構成とし、スクレーパ(29)には、移動方向に対して所定角度に傾斜する傾斜刃縁(29a,29a)を清掃プレート(28)から左右方向に突設させて形成し、傾斜刃縁(29a,29a)を各シーブ(26)の上面に摺接させる構成とする。【選択図】図10
