PROBLEM TO BE SOLVED: To provide a device for displaying the tilling depth of puddling implements, which makes tilling depth constant in puddling operation and maintains straightness of a traveling body during acertaiment of tilling depth.SOLUTION: The device 40 for displaying the tilling depth that is equipped with a first land grading plate 11 rotatably provided in a prescribed manner in the vertical direction behind a rotatably supported tilling rotor and a second land grading plate 12 rotatably provided in a prescribed manner behind the first land grading plate and leveling the surface of tilled soil is mounted on a puddling implement 1 fitted to the traveling body 90. The device 40 has a link mechanism part 41 having one side rotatably connected to a body 5 and the other side rotatably connected to the second land grading plate 12 and rotating in the vertical direction with the rotation of the second land grading plate 12 relative to the first land grading plate 11 according to tilling depth of the tilling rotor and a display part 50 for displaying tilling depth according to the rotation. The display part 50 is arranged at the extension tip of sight line of a worker M riding in the traveling body 90 when the worker M turns around obliquely backward toward the puddling implement 1.COPYRIGHT: (C)2013,JPO&INPIT【課題】代かき作業時に耕深を一定にすることができ、耕深の確認時に走行機体の直進性が維持できる代かき作業機の耕深表示装置を提供する。【解決手段】耕深表示装置40は、回転自在に支持された耕耘ロータの後方に上下方向に回動自在に配設された第1整地板11とこの後部に上下方向に回動自在に配設されて耕土表面を均平にする第2整地板12とを備えて走行機体90に装着される代かき作業機1に搭載される。耕深表示装置40は、一端側が機体5に回動自在に接続されて他端側が第2整地板12に回動自在に接続され耕耘ロータの耕深に応じた第1整地板11に対する第2整地板12の回動に伴って上下方向に回動するリンク機構部41と、この回動に応じて耕深を表示する耕深表示部50とを有する。耕深表示部50は、走行機体90に搭乗した作業者Mが代かき作業1に向かって斜め後方へ振り返ったときの作業者Mの視線の延長先に設けられる。【選択図】図2
