PROBLEM TO BE SOLVED: To provide a threshing apparatus which is configured such that a second processing cylinder is disposed above a first processing cylinder located on a lateral side of a threshing cylinder, returned tailings lifted up from the first processing cylinder are scattered by the second processing cylinder, removal of grains from rachis branches or the like or separation of waste straw is securely performed, and which provides improved tailing return performance.SOLUTION: The first processing cylinder (10) for processing the received tailings returned after threshing and sorting, is disposed on a lateral side of the threshing cylinder (4) pivotally supported in a threshing chamber (3), in parallel with each other, and the second processing cylinder (17) for taking in and processing the objects to be processed which are lifted by the rotation of the first threshing cylinder (10), is disposed above the first processing cylinder (10).COPYRIGHT: (C)2013,JPO&INPIT【課題】扱胴の横側部に並置した第1処理胴の上方に第2処理胴を配置することで、第1処理胴によって持ち上げられた2番処理物を第2処理胴によって拡散処理し、枝梗などの脱粒処理や藁屑との分離を確実に行い、2番処理性能を向上させる。【解決手段】扱室(3)内に軸架した扱胴(4)の横側に、脱穀選別後の2番還元物を受け入れて処理する第1処理胴(10)を平行に配置し、この第1処理胴(10)の上方には、第1処理胴(10)の回転によって持ち上げられた処理物を取り込んで処理する第2処理胴(17)を配置する。【選択図】 図3
