<P>PROBLEM TO BE SOLVED: To provide a walking type rice planting machine including a reduced number of components, having an excellent maintainability, and having a seedling stopper holding structure capable of setting a working point for a seedling stopper low. <P>SOLUTION: The walking type rice planting machine includes the seedling stopper 240 disposed below a seedling table 61 in such a way as rotatable in the vertical direction for preventing vertical feeding of a seedling mat 66 by abutting to the lower end of the seedling mat 66 placed on the seedling table 61. The seedling stopper 240 is comb-shaped, and includes: an abutting part 241a at the distal end of the seedling stopper 240 to abut to the lower end of the seedling mat 66; fitting parts 243R, 243L, 244R and 244L at the proximal end of the seedling stopper 240 to be fitted to a support member 230 laterally laid at a prescribed height position from a seedling placing surface 61a; and cams 245 disposed on at least one side of the fitting parts 243R, 243L, 244R and 244L to be engaged with the support member 230 so that the seedling stopper is held at a standby position or at a working position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
