PROBLEM TO BE SOLVED: To reduce a loss outside a machine by reducing a fourth loss in a threshing apparatus.SOLUTION: The threshing apparatus is constituted such that a threshing chamber (15) rotationally mounted with a threshing cylinder (18) communicates with a dust discharging chamber (17) through a communication port (23), that a sorting chamber (2) having a swing sorting shelf (3) is arranged on the lower side of the threshing chamber (15) and that a threshing port (21) is opened to the side of the threshing chamber (15). A recovery chamber (56) for recovering free grains over rack by threshing teeth (19) provided at the rear end of the threshing cylinder (18) is formed at a portion on the rear side of the communication port (23) in the threshing chamber (15), and a partition plate (55) partitioning the recovery chamber (56) from the threshing chamber (15) is formed by joining a first partition plate (55a) mounted to the lower face of a threshing cylinder cover (43) covering the upper part of the threshing cylinder (18), to a second partition plate (55b) mounted to a frame (48) on the upper side of the threshing port (21).COPYRIGHT: (C)2013,JPO&INPIT【課題】脱穀装置における四番ロスを減少させ、機外損失を低減する。【解決手段】扱胴(18)を軸架した扱室(15)と排塵処理室(17)とが連通口(23)で連通され、扱室(15)の下側には揺動選別棚(3)を有した選別室(2)が配置され、扱室(15)の横側には扱口(21)が開口された脱穀装置において、扱室(15)における連通口(23)よりも後側の部位に、扱胴(18)後端部の扱歯(19)によってささり粒を回収するささり粒回収室(56)が形成され、扱室(15)とささり粒回収室(56)との間を仕切る仕切板(55)が、扱胴(18)の上方を覆う扱胴カバー(43)の下面に取り付けられた第1仕切板(55a)と、扱口(21)の上側のフレーム(48)に取り付けられた第2仕切板(55b)との接合によって形成された構成とする。【選択図】図9
