PROBLEM TO BE SOLVED: To provide a transplanter automatically lifting a transplanting machine when a traveling machine body goes backward, and in which an instrument for automatically lifting the transplanting machine when carrying out steering operation is provided at low cost.SOLUTION: The transplanter is equipped with the transplanting machine 6, an effector 61 turnably supported so as to operate the transplanting machine 6 upward or downward, an elastic member 67 for biasing the effector 61, a locking member 68 for locking the turning of the effector 61 by the biasing force of the elastic member 67, a releasing mechanism 69 for turing the effector 61 by the biasing force of the elastic member 67 by releasing the lock by the locking member 68 according to the backward-motion switching operation of the traveling machine body 3, and a backward-motion lifting mechanism, automatically moving the transplanting machine 6 so as to be lifted by interlocking with the backward-motion switching of the traveling machine body 3. An interlocking mechanism 35 for releasing the lock by the locking member 68 so as to be mechanically interlocked with the steering operation of a prescribed amount by a steering handle 18 is installed in the transplanter to lift the transplanting machine 6 by the release of the lock.COPYRIGHT: (C)2013,JPO&INPIT【課題】走行機体の後進時に植付作業機を自動的に上昇させる移植機において、操向操作時に自動的に植付作業機が上昇させる手段を、低コストで設けた移植機を提供することを課題としている。【解決手段】植付作業機6と、植付作業機6を昇降作動させるように回動可能に支持された作動体61と、作動体61を付勢する弾性部材67と、弾性部材67の付勢力による作動体の回動をロックするロック部材68と、走行機体3の後進切換操作に伴ってロック部材68によるロックを解除して弾性部材67の付勢力により作動体61を回動させる解除機構69とを備え、走行機体3の後進切換に連動して植付作業機6を自動的に上昇駆動させる後進上昇機構を設けた移植機において、ステアリングハンドル18による所定量のステアリング操作に機械的に連動して前記ロック部材68によるロックを解除する連係機構35を設け、該ロック解除により植付作業機6を上昇させた。【選択図】図4
