GRAIN-UNLOADING AUGER FOR COMBINED HARVESTER

摘要

PROBLEM TO BE SOLVED: To achieve a grain-unloading auger for a combine harvester which can reduce the resistance of making a first screw and a second screw retractile relative to each other while is preventing shakiness stemming from the vibrations or the like of a second screw blade.;SOLUTION: The grain-unloading auger 9 for a combine harvester has the following structure: a gap formed between the inner circumferential end of a second screw blade 53 at a non-stationary portion La and the outer circumferential face of a first shaft body 42 includes a smaller gap portion Lc for supporting the second screw blade 53 on the first shaft body 42 and a larger gap portion Ld larger than the smaller gap portion Lc.;COPYRIGHT: (C)2010,JPO&INPIT
