PROBLEM TO BE SOLVED: To provide a selection part for a threshing apparatus, enabling a cost to be reduced by the simplification of a structure while enabling the selection operation to be carried out in a proper state even when the operation conditions are different by improving on the configuration of a grain sieve.SOLUTION: The selection part for the threshing apparatus is constituted as follows. The grain sieve 81 for leaking and selecting grains is installed in a swinging selection mechanism for carrying out the selection treatment while swinging and moving a thresh-treated product, and the grain sieve 81 is equipped with a frame body 96 surrounding the outer periphery part, and perforated members 97 supported by the frame body 96 and for leaking down the grains. The grain sieve 81 has a plurality of leaking-down operation regions Z1 and Z2 divided along the conveyance direction of the treated product, and is constituted in a state in which the perforated members 97 are individually and detachably supported by each of the leaking-down operation regions Z1 and Z2.COPYRIGHT: (C)2013,JPO&INPIT【課題】グレンシーブの構成に改良を加えることで、作業条件が異なっても適正な状態で選別作業を行うことが可能でありながらも、構成の簡素化によりコスト低減が可能となる脱穀装置用の選別部を提供する。【解決手段】脱穀処理物を揺動移送しながら選別処理する揺動選別機構に穀粒を漏下選別するグレンシーブ81が備えられ、このグレンシーブ81が、外周部を囲う枠体96とその枠体96にて支持される穀粒漏下用の多孔状部材97とを備えて構成され、且つ、処理物移送方向に沿って分割される複数の漏下作用領域Z1,Z2を備えるとともに、各漏下作用領域Z1,Z2の夫々に各別に多孔状部材97を着脱可能に支持する状態で備えて構成されている。【選択図】図5
