Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanting machine having a seedling table and a planting claw for continuously performing a seedling planting operation.
The present invention relates to a seedling mounting device for a rice transplanter in which the entire left and right widths of a seedling mounting table are reduced.

[0002]

Conventionally, in a multi-row seedling mounting table having, for example, 8 or more rows, there is a means for folding the seedling mounting table for one row at the outermost left and right ends approximately 90 degrees forward. In general, the seedling stand support shoe, which guides and supports the lateral movement on the upper part of the seedling stand, is usually arranged only on the central body side of the seedling stand. But 2
In the case of a means to fold a multiple-row seedling mounting table with more than one row,
Since the support shoe can support the seedling table only in a narrow area on the side of the central body, there is a problem in that the stability of the seedling table support and the durability of the support shoe are lacking.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a plurality of left and right ends of a seedling placing table are provided on the center main body side of the seedling placing table so as to be freely foldable. A plurality of seedling table support shoes on the upper part of the seedling table, which guide the movement, are arranged on both the central body side and the folding side of the seedling table, and the seedling table support shoes provide stable and stable support for the seedling table. The load applied to the platform support shoe is reduced, and the platform support shoe can be supported with good durability.

Further, when the seedling table support shoe on the folding side is provided so as to be switchable between the working position and the storage position and the seedling table is folded to reduce the entire width of the seedling table on the left and right, the seedling table on the folding side is set. The supporting shoe that supports it is also switched to the storage position, and the outermost width on the left and right is reduced to make storage and transportation of the rice transplanter convenient.

Further, a U-shaped support body to which a plurality of seedling stand support shoes are attached is connected and supported to a column that supports the seedling stand so that it can be rolled freely, and a plurality of support shoes are provided on the same U-shaped support body having high rigidity. Is installed with good dimensional accuracy to improve the planting accuracy, and a hydraulic device for rolling control can be installed inside the U-shaped support body, and the safety protection of this hydraulic device can also be achieved by the support body. Is.
