PROBLEM TO BE SOLVED: To provide a threshing apparatus that solves the problems, wherein significant waste straw cloggings occur at a part of a sieve, and for cleaning up all the waste straw deposited at the sieve, the structure of a threshing apparatus becomes complex and leads to increase in cost.SOLUTION: The threshing apparatus has a constitution, such that a sieve 23 is constituted of initial-end-side-fixed sieves 26, each with its tilt angle fixed set above the exhaust port 25 of a threshing chamber 11, and terminal-end-mobile sieves 27, each with its tilt angle set controllable downward, from below the exhaust port 25, wherein the initial-end-side-fixed sieves 26 are collocated with their mutual spaces which are narrower than those of the terminal-end-mobile sieves 27 and are provided with plates 30 which are orthogonal thereto so as to be freely moving in the longitudinal direction thereof.COPYRIGHT: (C)2009,JPO&INPIT【課題】シーブの一部で藁屑の詰まりが激しいという課題、全てのシーブの付着藁屑を清掃するため、構造が複雑になり、コスト上昇の原因となる課題がある。【解決手段】シーブ23は脱穀室11の排出口25よりも上手側に設けた傾斜角度が固定の始端側固定シーブ26と、排出口25の下方から下手側に設けた傾斜角度調節自在の終端側可動シーブ25とにより構成する。始端側固定シーブ26は前記終端側可動シーブ27よりも間隔を狭くして並設し、前記始端側固定シーブ26には、該始端側固定シーブ26と直交する方向のプレート30を始端側固定シーブ26の長さ方向に移動自在に設けたことを特徴とする脱穀装置。【選択図】図2
