As shown in the publications of No. 3221, there is a technique for reducing the external dimensions of the seedling stand by bending the outer side toward the upper side.

However, in the prior art, since the rows on the outside of the seedling table are connected by hinges, the ribs between the rows or the seedling pine presser on the top side of the seedling table come into contact with each other, preventing the rows from completely bending. This is not possible, and the row stand is bent to stand up (slanted) on the top side of the seedling stand.
There were structural and functional problems such as the need to provide means for maintaining the folded position on the pedestal.

However, the present invention provides a seedling platform device for a rice transplanter in which a strip on the outside of the seedling platform is provided so as to be bendable to the inside of the machine, and a seedling pine presser is installed on the top side of the seedling platform. The outer part of the seedling pine presser is separably connected to the central main body of the seedling pine holder via a hinge, and the strip of the outer part of the seedling support is fixed to the said part, and the pivot point of the hinge is the center of rotation. The present invention is characterized in that it is constructed so that the row stand and the divided plants are rotated and moved toward the upper surface of the seedling stand.

Therefore, since the row base on the outer side of the seedling pine holder is attached using the seedling pine holder, it is possible to use the outer part of the pine holder as a part of the hinge, and
The row stand can be completely bent and supported through the seedling pine presser on the upper surface of the seedling stand, and the folding connection structure of the seedling stand can be simplified and the bending function can be easily improved compared to the past. It is something.
