PROBLEM TO BE SOLVED: To provide a sulky rice transplanter making the seedling feeder assembling work easy and capable of performing the transfer roller changing work after assembling without overhauling a supporting frame.SOLUTION: A transport roller 31 of a seedling feeder 24 comprises a cylindrical roller body 40 and right and left shafts 37, 37 projecting from right and left of the roller body 40 to be freely rotatably inserted to a supporting frame 36, and the right and left shafts 37, 37 are made to be withdrawable in the roller body 40 with resistance to elastic force of an elastic body 45 set in the roller body 40. On the roller body 40, large-diameter transfer parts 41, 41 are set at both the side parts and a small-diameter pivoting part 42a is set between the transfer parts 41, 41, and the shafts 37, 37 are supported to be withdrawable, with the support holes 46, 46 set at the right and left both side surfaces of the transfer parts 41, 41 and the small-diameter pivoting part 42a. Further, the roller body 40 is composed with two same form split bodies 43, 43 provided by splitting in the shaft direction and the right and left shafts 37, 37 are composed to be the same form. |
