は施肥ホースなどとの干渉を回避させる必要がある。Conventionally, for example, in a multi-row seedling mounting table having eight or more rails, there is a means for folding a single-row seedling mounting rack at the left and right outermost ends approximately 90 degrees forward. However, if the left and right endmost two rows of seedling stands are folded in this way in order to further reduce the left and right total width, the lowermost part of the folded seedling stands will protrude from the lowermost part of the planting part and interfere with the ground There are inconveniences such as doing. In addition, in the case of such a folding method, the frame or the like for folding is placed in a surplus space between the main unit and the back of the seedling mounting table. It is necessary to avoid interference with a fertilizer hose or the like in a device equipped with a fertilizer application tank.

作業を可能とさせたものである。SUMMARY OF THE INVENTION Accordingly, the present invention relates to a seedling mounting device for a rice transplanter for folding a plurality of divided seedling mounting stands on the left and right ends of the seedling mounting base toward a seedling mounting base body via a folding frame. The pivoting length of the folding frame connecting the main body side and the split side of the seedling mounting table is slightly larger than the length at the time of connecting and fixing the main body side of the seedling mounting base and the split side, By increasing the turning radius of the folding frame at the time of folding or expanding the left and right divided seedling mounting tables, opening between the connecting parts on the main body side and the split side, these connection and disconnection are surely performed, This makes it possible to smoothly fold or expand the divided seedling mounting table.

At the time of expansion fixation by pulling the table to the main body side seedling mounting table, by bending the folding frame almost uniformly,
A gap formed between the main body side and the split-side seedling mounting table is favorably absorbed, and the split seedling mounting table is smoothly and accurately expanded and fixed.
