PROBLEM TO BE SOLVED: To provide a transplanter for precisely carrying out the transplanting in a field or in an opening part of a mulch sheet.SOLUTION: The transplanter 1 includes a transplanting part 7 for transplanting seed bulbs at a prescribed interval in the field while traveling. The transplanting part 7 includes an endless body 71 rotating in the upper and lower direction, seed bulb holder units having hole-opening devices, and attached to the upper part of the endless body 71 at a prescribed interval, and an extruding device 77 for transplanting the seed bulb in the field face by pushing the seed bulb when the seed bulb holder unit is positioned at the lowest end. A lifting and lowering linking mechanism 21 is installed between the center rear part of the transplanting part 7 in the right and left direction, and the center part of the rear part of a machine frame 2 in the right and left direction, and a lifting and lowering actuator 24 is installed between the front part of the lifting and lowering link mechanism 21 and the machine frame 2. A transplanting height-detecting means for detecting the height of the transplanting part 7 based on the transplanting surface 9 is installed in the transplanting part 7, and the lifting and lowering actuator 24 is operated by a controlling means so that the value detected by the transplanting height-detecting means may be a set height in the transplanter.COPYRIGHT: (C)2010,JPO&INPIT【課題】圃場もしくはマルチシート開孔部へ的確に植付けを行う植付機を提供する。【解決手段】圃場に、走行しながら所定間隔をおいて種球の植付けを行う植付部7を有する植付機1であって、植付部7は、上下方向に回転する無端体71と、該無端体71上に所定間隔毎に取付けられる開孔機付きの種球ホルダユニットと、該種球ホルダユニットが最下端に位置した時に種球を押し付けて圃場面に植付ける押出し装置77とを備えるとともに、前記植付部7の左右方向中央後部と、機体フレーム2後部左右中央部との間に昇降リンク機構21を設け、該昇降リンク機構21の前部と機体フレーム2との間に昇降アクチュエータ24を設け、前記植付部7には植付面9に対する前記植付部7の高さを検知する植付高さ検知手段を設け、該植付高さ検知手段の検出値が設定高さとなるように前記昇降アクチュエータ24を制御手段により作動させる。【選択図】図1
