Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice paddy planter having a relatively large number of planting lines, and in particular, a seedling planting device is vertically connected to a rear portion of a traveling vehicle body and spare seedlings are stored side by side. The present invention relates to a passenger rice transplanter equipped with a traveling vehicle body with a spare seedling stand placed between the seedling stand of the seedling planting device and a driver's seat.

[0002]

2. Description of the Related Art As a riding rice transplanter equipped with a seedling stand for spare seedlings as described above, for example, as disclosed in Japanese Patent Publication No. 58-11805, a seedling stand between a seedling planting device and a driver's seat is used. The spare seedling stand placed on the running car body can be divided into two parts, left and right, and the split left and right seedling stand parts are rotated forward of the running car body and folded back and forth. It is known that it is configured as follows.

[0003]

Since the above-mentioned preliminary seedling stand is configured to mount and store a horizontal preliminary seedling in the front-rear direction, the seedlings of the seedling planting device for arranging the preliminary seedling stand are arranged. It was necessary to leave a large space in the front and back between the stand and the driver's seat, which made the entire length of the machine including the seedling planting device large. Also, since the split left and right spare seedling stand portions are rotated and folded in a horizontal posture, the outer ends of the folded spare seedling stand portions will project laterally outward from the aircraft. Even if the seedling planting device is removed, the width of the entire machine including the spare seedling stand will be large, which will be inconvenient when storing in a garage or loading on a vehicle.

According to the present invention, it is possible to suppress an increase in the entire length of the machine body including the seedling planting device by improving the foldable spare seedling stand, and to keep the spare seedling stand even in the folded state. The purpose is to prevent the lateral width of the entire machine body including it from increasing.
