PROBLEM TO BE SOLVED: To obtain an inexpensive seeding transplanter which mechanically automatically raise a planting device when turning.SOLUTION: The seedling transplanter includes: a pitman arm 60 for controlling the direction of a wheel 10 of a traveling vehicle body 2 a planting device provided at the rear side of the traveling vehicle body 2 and lifted by a lifting hydraulic cylinder a planting lifting lever 33 for lifting the planting device, and for setting the planting a cam 74 for controlling the lifting hydraulic cylinder in accordance with the operation of the lifting lever 33 a positioning roller 77 link members 61, 62, 64, 71 connected with the pitman arm 60 and a turning switch operation tool 73 connected with the link members 61, 62, 64, 71. The turning switch operation tool 73 can select between a mode for raising the planting device 52 by mechanically driving the cam 74, the roller 77, or the like when a steering member rotates for not less than a predetermined amount and a mode not for driving the cam 74, the roller 77, or the like even when the steering member rotates for not less than the predetermined amount.COPYRIGHT: (C)2012,JPO&INPIT【課題】 旋回時、植え付け装置を機械的に自動上昇させる、安価な苗移植機の実現。【解決手段】 走行車体2の車輪10の方向を制御するピットマンアーム60と、走行車体2の後側に設けられ、昇降油圧シリンダによって昇降させられる植え付け装置と、植え付け装置の昇降、植え付けを設定するための植え付け昇降レバー33と、昇降レバー33の操作に従って、昇降油圧シリンダを制御するカム74、位置決めローラ77等と、ピットマンアーム60に連結された連繋部材61、62、64、71と、連繋部材61、62、64、71に連結された旋回切替操作具73とを備え、旋回切替操作具73は、操舵部材が所定量以上回動すると、カム74、ローラ77などを機械的に駆動することによって植え付け装置52を上昇させるモードと、操舵部材が所定量以上回動しても、カム74、ローラ77などを駆動しないモードが選択出来る。【選択図】図3
