Claims

[Scope of utility model registration request]

A seedling planting device is installed on a traveling vehicle body supported by wheels so that it can be raised and lowered via a lower link and a top link, and the seedling planting device is configured to be raised and lowered by a lifting mechanism that moves the lower link up and down. In the riding rice transplanter made of
A pivot pin of the top link to the traveling vehicle body is configured to be movable in the longitudinal direction, and the pivot pin is connected to the elevator groove so that the lifting mechanism is switched between raising and lowering by moving the pivot pin back and forth. , and the elevating mechanism is configured to be switched between raising and lowering with an elevating operation lever, and the pivot pin is provided with a mechanism that prevents the pivot pin from moving back and forth only when the elevating operation lever is in the raised position. A float constant pressure device for a riding rice transplanter, comprising a means as described above.
