PROBLEM TO BE SOLVED: To improve the working performance of supply of seedlings to a seedling platform in a rice planting machine.SOLUTION: A rice planting machine is provided with a seedling platform 10 which is reciprocated, traversed and driven along left and right directions. The rice planting machine includes: a seedling planting device 5 supported to lifting/lowering mechanisms 3, 4； and a preliminary seedling platform 21 arranged in the rearward portion of the machine body 11. There are included movement support mechanisms 25, 29 for supporting the preliminary seedling platform 21 to the machine body 11 in the left and right directions in a freely reciprocating/moving manner. There is included an interlocking member 31 which connects the preliminary seedling platform 21 with the seedling platform 10 to transmit the lateral movement of the seedling platform 10 to the preliminary seedling platform 21, laterally moves the preliminary seedling platform 21 along with the seedling platform 10, and guides the seedlings of the preliminary seedling platform 21 from the preliminary seedling platform 21 to the upper part of the seedling platform 10.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】田植機において、苗のせ台への苗の補給の作業性を向上させる。【解決手段】左右方向に沿って往復横送り駆動される苗のせ台１０が設けられて、昇降機構３，４に支持された苗植付装置５と、機体１１の後部に設けられた予備苗のせ台２１とが備えられる。予備苗のせ台２１を左右方向に往復移動自在に機体１１に支持する移動支持機構２５，２９が備えられる。予備苗のせ台２１と苗のせ台１０とを接続して、苗のせ台１０の横移動を予備苗のせ台２１に伝達し、予備苗のせ台２１を苗のせ台１０と一緒に横移動させ、且つ、予備苗のせ台２１の苗を予備苗のせ台２１から苗のせ台１０の上部に案内する連動部材３１が備えられる。【選択図】図１
