GRAIN CULM-RAISING DEVICE IN COMBINE HARVESTER OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To improve durability of a lug-raising guide rail for standing a raising lug in a grain culm-raising device in a combine harvester or the like.;SOLUTION: The grain culm-raising device 7 is constituted as follows. A raising chain 11 equipped with the raising lugs 14... for raising the planted grain culms and axially supported thereby is wound around upper and lower wheel bodies 12, 13 of a raising case 7c of the grain culm-raising device 7. When constituting the lug-raising guide rail 15 arranged along the raising chain 11 up and down, a rail plate part 15a having a prescribed width and being long up and down is joined with an attaching plate part 15b having the nearly same recessed cross section shape and being long up and down so as to constitute a space part long up and down in the interior. Upper and lower both terminal sides of the lug-raising guide rail 15 are constituted symmetrically from the center part up and down so that the lug-raising guide rail 15 can detachably be attached to the raising case 7c by inverting the lug-raising guide rail 15 up and down.;COPYRIGHT: (C)2008,JPO&INPIT
