DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetable transplanter for receiving potted seedlings of one strain taken out from a seedling tray of a seedling mounting stand by a seedling picking out nail, for example, and sequentially planting the seedlings in a field.

[0002]

2. Description of the Related Art Conventionally, a cultivation roller is provided behind a planting claw,
There was a technique for cultivating potted seedlings planted with planting claws.

[0003]

In the prior art, since the lowest position of the planting claw and the relative height of the cultivation roller are substantially constant, the planting depth of the seedlings is adjusted according to the field conditions or the type of crop. There were functional problems such as not being easily selectable.

[0004]

However SUMMARY OF THE INVENTION The present invention provides a floating freely support the planting unit up and down, the soil roller in the planting claw rear with relative positions adjustably mounted kicking of the planting unit, A planting lever that changes the relative position between the planting claw and the cultivation roller is provided. Compared with the conventional method, the planting depth of the seedlings can be easily selected according to the field conditions or the type of crop, etc. Seedlings can be planted deeply to facilitate the establishment of the seedlings.
