Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weeding seedling separating machine and a weeding seedling dividing method for dividing a weeding seedling which is dug from a field into a state in which it can be transplanted.

[0002]

2. Description of the Related Art Conventionally, when transplanting rush into paddy fields,
A plant suitable for planting after excavating the grass seedlings to be grown in the field using a scoop or plow, removing the mud attached to the plant part of the grass seedlings to be excavated with a mud-removing machine. Separately by hand, or while holding the stem portion of the rush plant after sloughing off, pass the plant part through a rotating sawtooth and cut vertically and horizontally to divide into stocks. However, each plant was manually planted in a paddy field.

[0003]

However, there is a drawback that the work of manually cutting each plant part of rush seedlings after mud dropping is troublesome and time-consuming. In addition, when the plant part is passed through a rotating sawtooth while holding the stem part and cut longitudinally and laterally, the cut width is uneven and the stocks are uneven, and it takes time to correct it. There was a problem.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to efficiently and efficiently divide the plant parts of rush seedlings after mud-falling into each uniform plant in a short time. Another object of the present invention is to provide a planting machine for planting seedlings and a planting method for planting seedlings, which is characterized in that it can be cut, and that the planting plant can be planted one by one by mounting the planting plant on the planting belt of the planting machine.
