SHAKING SEPARATOR OF THRESHER

摘要

PROBLEM TO BE SOLVED: To blast separation air in divided three parts, to provide three-stage separation and to improve separation performances. SOLUTION: A shaking separator 14 is equipped with a first and a second chaff sieves 26 and 28, a grain sieve 30 and a winnower fan 34 for performing a winnowing treatment of materials to be treated under a receiving net 22 of a threshing chamber 16 and two upper and lower wind direction plates 48 and 49 are arranged so as to face a blast port 35 provided on the rear side of the winnower fan 34. A first air passage 36 for air blasting between the first and the second chaff sieves 26 and 28, a second air passage 37 for air blasting between the second chaff sieve 28 and the grain sieve 30 and a third air passage 38 for air blasting to the lower part of the grain sieve 30 are formed with the two wind direction plates 48 and 49. The separation air from the winnower fan 34 is divided and blasted to each air passage. COPYRIGHT: (C)2005,JPO&NCIPI
