PROBLEM TO BE SOLVED: To enable an attached material on a fixed sieve to be certainly removed by a cleaning plate.SOLUTION: The threshing apparatus is constituted as follows. The cleaning plate (28) having plate faces in the upper and lower directions is installed in a sieve (17) of a swinging selection shelf (15) for the swinging selection of the treated product dropped from a threshing chamber (2) to be freely movable in the right and left directions. Scrapers (29) having oblique blade edges (29a) tilted at a prescribed angle to the moving direction of the cleaning plate (28) are installed in the cleaning plate (28), and the oblique blade edges (29a) are constituted to be moved while making contact with the upper surface of the sieve plate (26) according to the movement of the cleaning plate (28) in the right and left directions. The scrapers (29) are installed on both of the right and left sides of the cleaning plate (28), and the oblique blade edges (29a) of the right and left scrapers (29) are formed into a nearly truncated chevron shape in the plane view.COPYRIGHT: (C)2013,JPO&INPIT【課題】清掃プレートによる固定シーブ上の付着物の除去を確実に行えるものとする。【解決手段】扱室(2)から落下した処理物を揺動選別する揺動選別棚(15)のシーブ(17)に、上下方向の板面を有した清掃プレート(28)を左右方向移動自在に備え、この清掃プレート(28)には、清掃プレート(28)の移動方向に対して所定角度に傾斜する傾斜刃縁(29a)を有したスクレーパ(29)を備え、清掃プレート(28)の左右方向移動によって傾斜刃縁(29a)をシーブ板(26)の上面に摺接させる構成とする。また、スクレーパ(29)を清掃プレート(28)の左右両側に設け、この左右のスクレーパ(29)の傾斜刃縁(29a)を平面視で略ハの字型に形成する。【選択図】図5
