Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to, for example, a transplanting machine for planting onion seedlings in a reed twice for a 4-row reed.
[0002]
[Prior art]
Conventionally, there have been transplanting machines in which two sets of two rotary pots and planting hole openers are installed in a traveling machine and two seedlings are planted simultaneously.
[0003]
[Problems to be solved by the invention]
When the rotary pots are arranged side by side, the interval between the seedling positions from each rotary pot to the planting hole opener becomes wide, so the first and second strips from the end and the two strips adjacent to the third and fourth strips simultaneously. Cannot be planted, and the first and third articles from the end and the second and fourth articles are planted at the same time, but the first and second articles from the end, and the adjacent two articles from the third and fourth articles Is not stable, it becomes extremely difficult to work with a harvesting machine that harvests two adjacent strips simultaneously. In addition, the position of seedling feeding from the operator to each rotary pot has become far, and it has not been possible to cope with short-to-short transplants and high-speed transplants, and there has been a problem that work efficiency is difficult to increase.
[0004]
