PROBLEM TO BE SOLVED: To provide accurate furrow-coating and shaping work by improving the balance in the longitudinal direction between a travelling machine body and a working machine while moving.SOLUTION: The furrow-coating machine includes: an attaching part to be attached to the travelling machine body an offset mechanism part which can move in the lateral direction from the attaching part a working part 20 which is disposed rotatably in the horizontal direction with the center of rotation of a power transmission shaft 51 disposed on the moving end side as a rotation fulcrum O, and which has a pretreatment body 21 and a furrow shaping body 40 and a power transmission mechanism part 50 for rotationally driving the working part 20 with the power from the travelling machine body. The rotation fulcrum O is disposed on an intersection point O between the rotation center axis of the furrow shaping body 40 and the rotation center axis of the pretreatment body 21 as seen from the top. The power transmission mechanism part 50 includes a power branch part 65 on the front side in the direction of advancement of the travelling machine body from the rotation fulcrum O, and the power is transmitted to the furrow shaping body 40 via the power branch part 65. The power branch part 65 is disposed on the inner side of a polyhedral drum 41 of the furrow shaping body 40.COPYRIGHT: (C)2012,JPO&INPIT【課題】移動時の走行機体と作業機の前後バランスを向上させ、精度の良い畦塗り整形作業を提供する。【解決手段】畦塗り作業機は、走行機体に装着される装着部と、これから左右方向に移動可能なオフセット機構部と、この移動端側に配設された動力伝達軸51の回転中心を回動支点Oとして水平方向に回動可能に配設されて前処理体21及び整畦体40を有してなる作業部20と、走行機体からの動力によって作業部20を回転駆動させる動力伝達機構部50とを備える。回動支点Oは、平面視において整畦体40の回転中心軸と前処理体21の回転中心軸との交点O上に配置される。動力伝達機構部50は、回動支点Oよりも走行機体の進行方向前側に動力分岐部65を備え、動力分岐部65を介して動力が整畦体40に伝達される。動力分岐部65は整畦体40の多面体ドラム41内側に配設される。【選択図】図4
