TRANSPLANTER

To provide a transplanter stabilizing planting depths of seedlings by a planting unit and capable of enhancing vehicle speed in transplanting work.SOLUTION: The transplanter comprises: a traveling machine body 5 including a planting unit 100; a sensor unit 6 grounded on a planting surface 3; an actuator 30 lifting/lowering the traveling machine body 5; a lifting/lowering valve 32 actuatingly controlling the actuator 30; a changeover member 37 for changing over the lifting/lowering valve 32 among three states of lifting/neutral/lowering; and an interlock mechanism for interlocking the sensor unit 6 with the changeover member 37, where the lifting/lowering valve 32 is changingly actuated according to an actuation position of the changeover member 37 that is interlocked with the vertical movement of the sensor 6. The transplanter further includes a regulation unit 110 for regulating an operating range of the changeover member 37 of the lifting/lowering valve 32.SELECTED DRAWING: Figure 1 【課題】植付部による苗の植付深さの安定化を図り、且つ、移植作業時の車速の高速化が可能となる移植機を提供する。【解決手段】植付部１００を備えた走行機体５と、作付け面３に接地させる感知部６と、走行機体５を昇降するアクチュエータ３０と、アクチュエータ３０を作動制御する昇降バルブ３２と、昇降バルブ３２を上昇・中立・下降の３状態に切り換える切換部材３７と、感知部６と切換部材３７とを連動する連動機構と、が備えられ、感知部６の上下動に連動する切換部材３７の作動位置に応じて昇降バルブ３２が切り換え作動される移植機であって、昇降バルブ３２の切換部材３７の作動範囲を規制する規制部１１０が備えられている。【選択図】図１
