<p>PROBLEM TO BE SOLVED: To provide a support structure capable of obtaining a stable rotation even when a support roller supporting an eccentric disk of a raking reel is worn away.SOLUTION: In a reaping part 2 of an ordinary-type combine-harvester 1 including a raking reel 30 having a structure in which a reel disk 32 is fixed to both left and right sides of a reel shaft 31, and an eccentric disk 35 is arranged eccentrically to the side of the reel disk 32 on one lateral side, a mounting hole 35b is opened at a center part of the eccentric disk 35. A guide surface 35a is formed around the mounting hole 35b. A support bracket 51 is fixed to a bearing part of the reel shaft 31. A plurality of support rollers 53 are rotatably placed around the support bracket 51 at a concentric position to the center of the eccentric disk 35. The support roller 53 is brought into contact with the guide surface 35a. A shaft center of the support roller 53 and the guide surface 53a are arranged so as to be inclined at the same angle with respect to a shaft center of the eccentric disk 35.</p> |
