Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter for continuously carrying out seedling planting operations, for example, comprising a seedling mounting table and planting claws.
The present invention relates to a seedling mounting device for a rice transplanter that reduces the entire left and right width of a seedling mounting table. Conventionally, for example, in a multi-row seedling mounting table having eight or more rows, a single-row seedling mounting table at the left and right outermost ends is folded forward by approximately 90 degrees. In the means, the seedling supporting shoes for guiding and supporting the right and left movement at the upper part of the seedling mounting are usually arranged only on the central body side of the seedling mounting. But 2
In the case of a means to fold a plurality of seedling mounting tables,
Since the seedling table can be supported by the support shoe only in a narrow range on the center main body side, there is a problem that the stability of the seedling table support and the durability of the support shoe are lacking. [0003] Accordingly, the present invention SUMMARY OF] is a plurality Article seedlings loading table left and right ends, only set freely folded to the center body of the seedling mounting table, to guide the lateral movement of the seedling mounting table the Naeno stand seedling stand supporting shoe, the seedling transfer device of rice transplanter be disposed both seedling placing stand central body side and the folded side, planting the planting unit
The right and left supports are erected on the case, and the link between the left and right supports is connected.
Fix the seedling support shoe on the main body to the support to be fixed to the rod
And attach the seedling support shoes on the split base to the upper ends of the left and right supports.
The fixed table to be installed is supported via a rotating plate and a mounting plate,
A switching handle is provided on the rotating plate, and the switching handle is
While keeping the seedling support shoe horizontal by projecting outward,
Rotate the switching handle down to move the seedling stand support
It is used to store the durable, durable and good support,
This makes it easier to store and transport rice transplanters.
