PROBLEM TO BE SOLVED: To steadily adjust between seedlings by a simple transmitting mechanism.SOLUTION: In the seedling transplant in which the transplanting part is elevatably coupled to the rear part of the running part and seedlings are transplanted in the agricultural field by the transplanting part towed by the running part, driving force can be transmitted from an engine arranged in the running part to the input shaft of the transplanting part via a transmitting mechanism, an intra-seedling adjusting mechanism is arranged in the middle part of the transmitting mechanism, the intra-seedling adjusting mechanism is arranged in the running part, a clutch case is arranged near the intra-seedling adjusting mechanism in the middle part of the transmitting mechanism, the intra-seedling adjusting mechanism is interlockingly coupled to the clutch mechanism arranged in the clutch case, the connecting/disconnecting timing of the clutch mechanism is adjusted by the intra-seedling adjusting mechanism in which between seedlings is adjusted, the driving force is intermittently transmitted from the engine to the transplanting part.COPYRIGHT: (C)2012,JPO&INPIT【課題】簡易な伝動機構で堅実に株間を調節すること。【解決手段】走行部の後方に移植部を昇降自在に連結して、走行部に牽引される移植部により圃場に苗を移植するようにした苗移植機において、走行部に設けたエンジンから伝動機構を介して移植部の入力軸に動力を伝動可能とし、伝動機構の中途部に株間調節機構を設けるとともに、株間調節機構は走行部に配設した苗移植機であって、前記伝動機構の中途部にはクラッチケースを前記株間調節機構に近接させて設け、クラッチケース内に配設したクラッチ機構に株間調節機構を連動連結して、株間調節された株間調節機構によりクラッチ機構の接続・切断タイミングが調節されて、エンジンから移植部には動力が間欠的に伝達されるようにした。【選択図】図1
