[Problems to be solved by the invention]
However, when the plate-shaped seedling guide of the above (1) is fixedly installed at an interval 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 reduced. The seedlings may shift or fall, and if the above interval is adjusted to the width of the connected seedling group, the seedlings are separated by friction because the side surface of the connected seedling group comes into contact with the plate-shaped seedling guide. It is worn out when it is done.
[0007]
In the case where the seedling guide composed of the rotating belt of the above (2) is provided, when the connecting seedling groups having different widths, that is, the wide connecting seedling group and the narrow connecting seedling group are arranged one after the other, the rotating belt is used. A group of connected seedlings that are conveyed while being guided in contact with the group and a group of connected seedlings that are not in contact with the rotating belt and are therefore conveyed without being guided are generated, and the position of the connected seedling group with respect to the individual seedling separation mechanism is shifted. Or the seedlings on the edge fall.
[0008]
Further, in the case where the seedling bias receiving and rotating body composed of the guide belt of the above (3) is provided at an interval slightly wider than the width of the connected seedling group, when the transplanter travels on the slope, the connected seedling group is moved to one side. The conveyed seedlings are conveyed while being brought into contact only with the guide belt, and consequently, the connected seedling group is conveyed to the row-seedling separating mechanism in a deviated state.
[0009]
The present invention eliminates the need for installation of the plate-shaped seedling guide, the seedling guide formed of a rotating belt or the seedling bias receiving rotating body itself, eliminates the above-mentioned various inconveniences, and separates the connected seedling group into individual seedling separating mechanisms or rows. It is intended to be accurately transported to the seedling separation mechanism.
