<P>PROBLEM TO BE SOLVED: To make a selected material smoothly flow in a swing direction and to effectively perform a sieve selection by swinging. <P>SOLUTION: The swing selector of a thresher is equipped with a swing selection rack (15) that is furnished with a transfer rack (16), a first sieve group (17), a second sieve group (18) and a straw rack (19) in this order from the upstream side in the transfer direction of the selected material below a threshing chamber (2) swingably back and forth. The swing selection rack (15) is equipped with a plurality of cleaning members (30) composed of a plate (28) along the swing direction of the swing selection rack (15) and a scraper (29) that is brought into contact with a sieve (26) face of the first sieve group (17) or a sieve (27) face of the second sieve group (18) and removes an attachment at intervals mutually in the horizontal direction perpendicular to the swing direction of the swing selection rack (15). Drive mechanisms (34, 35, 36, 37, 38, 39 and 40) for reciprocatingly swinging the cleaning members (30) in the horizontal direction are installed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
