Claims

[Scope of Claim for Utility Model Registration] (1) A seedling mounting table on which transplanted seedlings are placed and reciprocated in a horizontal direction with a predetermined stroke;
A slide block is provided on the slide rod linked to the seedling platform, and a guide piece is fitted into the slide block so as to be rotatable in the axial direction, and a guide section is provided at the axial end of the guide piece. In a seedling platform traversing device comprising a screw shaft that rotates in a predetermined direction and has a continuous screw groove that engages with the screw shaft, the outer wall of the screw groove at the outer end of the screw shaft is connected to the screw shaft. A device for transversely feeding a seedling stand for a transplanter, characterized in that the shaft diameter of the screw shaft up to the innermost part of the screw shaft is slightly smaller than the shaft diameter of the other main part of the screw shaft. (2) At the first screw groove intersection after the guide piece turns along the screw groove at the outer end of the screw shaft, there is a cutout located at the rear corner in the axial direction of the guide part in the advancing direction. 2. The device for transversely feeding a seedling platform of a transplanting machine according to claim 1, further comprising a section. (3) The guide piece according to claim (1) or (2), characterized in that the center of the screw shaft in the axial direction and the center of the guide piece in the axial direction of the screw shaft are arranged to be offset from each other. A transverse feeding device for the seedling platform of a transplanter. (4) Claim (1) or (2) or (3) characterized in that a recessed portion recessed toward the axis is formed in the bottom surface of the screw groove, and the guide piece is elastically supported so as to be pressed toward the recessed portion. ) A transverse feeding device for the seedling platform of the transplanter described in ).
