PROBLEM TO BE SOLVED: To reduce burden on a chaff sieve and increase sorting treatment performance by feeding grain to the top of the chaff sieve in the rear while sorting the grain coming down at a starting-edge side of a threshing chamber.SOLUTION: A threshing sorting apparatus of a combine includes a first sorting sieve (18) at the threshing chamber starting-edge side, a second sorting sieve (19) of the threshing chamber termination side, and a straw rack (20) received from the termination of the second sieving/sorting sieve, in a swing sorting shelf (17) for sieving and sorting the threshed grain by receiving the threshed grain coming down from a receiving net (11) of a threshing chamber (9). Grain collection units (27, 28) for collecting the grain coming down are provided under each of the first sorting sieve (18) and the second sorting sieve (19).SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】扱室の始端側で漏下する穀物を選別しながら後方のチャフシーブ上へ送ることで、チャフシーブ上での負担を軽くし、選別処理性能を高めること。【解決手段】コンバインの脱穀選別装置は、扱室(9)の受網(11)から漏下する脱穀処理物を受け入れてふるい選別する揺動選別棚(17)に、扱室始端側のふるい選別用第1選別シーブ(18)と、扱室終端側のふるい選別用第2選別シーブ(19)と、第2選別シーブの終端から受け入れるストローラック(20)とを備え、前記第1選別シーブ(18)と前記第2選別シーブ(19)の夫々の下方に、漏下した穀粒を回収する穀粒回収部(27,28)を設ける。【選択図】図2
