摘要：
PROBLEM TO BE SOLVED: To provide a working machine in which the planting depth of seedlings can be accurately adjusted by a simple structure.SOLUTION: A working machine comprises: a traveling body； a transplanter comprising a machine frame fitted to a rear part of the traveling body, and a planting device supported by the machine frame, and for planting seedlings in a field； an elevating/lowering driving device for elevating/lowering the machine frame with respect to the traveling body； a detecting member to be vertically moved so as to follow irregularities of the field； a wire to be moved in association with vertical movement of the detecting member； and a control valve for switching the elevating/lowering driving device between a first state for elevating the machine frame in association with movement of the wire, and a second state for lowering the machine frame.SELECTED DRAWING: Figure 30COPYRIGHT: (C)2020,JPO&INPIT【課題】簡易な構成で正確に苗の植付深さを調整することができる作業機を提供すること。【解決手段】作業機は、走行体と、前記走行体の後方に装着された機枠と、前記機枠に支持され且つ圃場に苗を植え付ける植付装置と、を有する移植機と、前記走行体に対して前記機枠を昇降させる昇降駆動装置と、圃場の凹凸に追従して上下動する検出部材と、前記検出部材の上下動に伴って移動するワイヤと、前記ワイヤの移動に伴って前記機枠を上昇させる第１状態と前記機枠を下降させる第２状態とに前記昇降駆動装置を切り換える制御バルブと、を備えている。【選択図】図３０
