PROBLEM TO BE SOLVED: To solve a problem such that in order to synchronizing the spot-sowing work and spraying work by a planting device in a transplanter, it is necessary to build-in a complex link mechanism, etc., between driving shafts for driving the planting device, and in order to apply it to the transplanter nipping/holding the seedlings at an outer circumference of a rotating nipping/holding disc pair, conveying them to a planting gutter in a field and spot-planting, a wide design change is required and its production cost is increased.SOLUTION: This transplanter includes a starting signal-transmitting means 109 for transmitting the starting signal 107 for starting the spraying by the spraying device 7 to meet with the spot-planting, a stopping signal-transmitting means 110 for transmitting the stopping signal 108 for stopping the spraying and a delivery-regulating means 92 for regulating the driving of a granular material-delivering part 63 based on the starting signal 107 and stopping signal 108 for synchronizing the spot-planting and granular material-spraying. On stopping the spraying, a conveying part 32a or 32b in the granular material-delivering part 63, for conveying the granular materials is held at a waiting position 121a capable of receiving the granular materials until the start of next spraying.COPYRIGHT: (C)2008,JPO&INPIT【課題】移植機で植付装置による点植作業と散布作業を同期するには、従来から、植付装置を駆動する駆動軸間に複雑なリンク機構等を組み込む必要があり、これを、回転する把持ディスク対の外周に苗を挟持させ圃場の植付溝まで搬送して点植する移植機に適用するには、大きな設計変更が必要で製造コストが増加する、という問題があった。【解決手段】点植に合わせ散布装置7による散布を開始させる起動信号107を発信する起動信号発信手段109と、散布を停止させる停止信号108を発信する停止信号発信手段110と、前記起動信号107と停止信号108に基づき散布装置7の粒状物繰出部63の駆動を制御する繰出制御手段92を備えて、点植と粒状物散布を同期させ、散布停止時には、粒状物繰出部63で粒状物を移送する搬送部32a又は32bを、次の散布開始まで、粒状物を受入可能な待機位置121aに保持する。【選択図】図10
