[Problems to be solved by the invention]
However, when the plate-shaped seedling guides of (1) are fixedly installed at intervals slightly wider than the width of the connected seedling group, if the interval is too wide, the position of the connected seedling group with respect to the individual seedling separation mechanism is The seedling at the end may fall, and if the distance is adjusted to the width of the connected seedling group, the side surface of the connected seedling group comes into contact with the plate-shaped seedling guide, so that the seedling is separated by friction. If worn, it will be worn out.
[0007]
In the case where the seedling guide body comprising the rotating belt of (2) is provided, when the connected seedling group having different widths, that is, the wide connecting seedling group and the narrow connecting seedling group are mixed, the rotating belt The connected seedlings that are transported while being in contact with the belt and the connected seedlings that are transported without being guided are generated, and the position of the connected seedlings with respect to the individual seedling separation mechanism is shifted. Or the seedling at the end may fall.
[0008]
In addition, when the seedling bias receiving rotating body including the guide belt of (3) is provided at an interval slightly wider than the width of the connected seedling group, when the transplanter travels on an inclined land, the connected seedling group is placed on one side. It is conveyed while being brought into contact only with the guide belt, and accordingly, the connected seedling group is conveyed to the row seedling separation mechanism in a biased state.
[0009]
The present invention eliminates the inconveniences described above by eliminating the need for installation of the plate-shaped seedling guide body, the seedling guide body comprising the rotating belt or the seedling bias receiving rotation body itself, and separates the connected seedling groups into individual seedling separation mechanisms or rows. It is intended to be conveyed accurately to the seedling separation mechanism.
