PROBLEM TO BE SOLVED: To provide a transplanter capable of accurately regulating the interval between stocks.SOLUTION: The transplanter is constituted as follows. A freely lifted and lowered transplanting body 158 for transplanting seedlings 2 by plugging into a ridge R when being lowered is provided at the rear part of a traveling body 3, and a detecting roller 161 rolling on the upper surface of the ridge R is provided on the front side of the transplanting body 158. A stock interval clutch 68 for turning off a power for lifting and lowering the transplanting body 158 for a required time when the transplanting body 158 is lifted is provided so that the seedlings 2 may be transplanted at a desired transplanting interval. A first stock interval sensor 69 for detecting the number of rotation of a transmission shaft 55 provided in a power transmission path of a traveling system of the traveling body 3, and a second stock interval sensor 176 for detecting the number of rotation of the detection roller 161 are provided. The off interval of the stock interval clutch 68 is controlled by the first stock interval sensor 69 when the number of the rotation of the detection roller 161 is smaller than a prescribed number, and the off interval of the stock interval clutch 68 is controlled by the second stock interval sensor 176 when the number of the rotation of the detection sensor 161 is not smaller than the prescribed number.COPYRIGHT: (C)2010,JPO&INPIT【課題】 株間を正確に制御することができる移植機を提供する。【解決手段】 走行体3の後部に、昇降自在で且つ下降した際に畝Rに突入して苗2を植え付ける植付体158を設け、植付体158の前方側に畝R上面を転動する検出ローラ161を設け、苗2が所望の植付間隔で植え付けられるように、植付体158が上昇した際に該植付体158を昇降させる動力を所要時間だけ切るための株間クラッチ68を設け、走行体3の走行系の動力伝達経路に設けられた伝動軸55の回転数を検出する第1株間センサ69と、検出ローラ161の回転数を検出する第2株間センサ176とを設け、検出ローラ161の回転数が所定未満である場合は第1株間センサ69によって株間クラッチ68の切断時間を制御し、検出ローラ161の回転数が所定以上である場合は第2株間センサ176によって株間クラッチ68の切断時間を制御する。【選択図】図18
