PROBLEM TO BE SOLVED: To provide a seedling transplanter in which a preliminary seedling frame is not switched between a seedling load mode and a fertilizer load mode due to vibration during planting or move-traveling, thereby preventing loaded seedlings or fertilizer from dropping.SOLUTION: The seedling transplanter has a preliminary seedling frame 38 for loading preliminary seedlings provided on a front part of a traveling vehicle body 2 thereof and a fertilizer stand 63 for loading fertilizer provided on a side of the preliminary seedling frame 38, the preliminary seedling frame 38 being made rotatable, so that seedling transplanter can switch between the seedling load mode for loading seedlings and the fertilizer load mode in which fertilizer is loaded on the fertilizer stand 63. The switching is performed by a rotation lock mechanism 66 of the preliminary seedling frame 38. When the rotation lock mechanism 66 is actuated, the preliminary seedling frame 38 can be prevented from switching between the seedling load mode and the fertilizer load mode due to vibration during planting or move-traveling. Consequently, dropping of the loaded seedlings or fertilizer is prevented, eliminating the need for gathering the dropped seedlings or fertilizer, preventing the seedlings from being damaged by the shock of the dropping and from causing poor growth with the result of improved quality of the seedlings, and preventing the packages or other containers of fertilizer from being broken open and the contained fertilizer from being scattered.COPYRIGHT: (C)2014,JPO&INPIT【課題】苗の植付作業中や移動走行中の振動で予備苗枠が苗積み形態と肥料積み形態とに切り替わることがなく、積載した苗や肥料の落下を防止できる苗移植機を提供すること。【解決手段】走行車体2の前部に設けた予備苗を積載する予備苗枠38の側方に肥料を積載する肥料載せ台63を設け、予備苗枠38を回動可能とすることで、苗を積載する苗積み形態と、肥料載せ台63に肥料を積む肥料積み形態とに切替可能な構成とし、前記切替を予備苗枠38の回動ロック機構66の切替で行う苗移植機であり、回動ロック機構66の作動により植付作業中や移動走行中の振動で予備苗枠38が苗積み形態と肥料積み形態とに切り替わることを防止できるので、積載した苗や肥料の落下が防止され、苗や肥料を拾い集める作業が不要となり、落下の衝撃で苗が傷付き生育不良を起こすことを防止でき、苗の品質が向上すると共に肥料を収容する袋等が破れて肥料が散乱することを防止できる。【選択図】図3
