PROBLEM TO BE SOLVED: To smoothly perform ridging and form a favorable ridge slope with high fixing strength by preventing sticking of soil right after a rotary tillage.SOLUTION: A ridging machine 1 includes: a tilling rotary 31 that excavates the ground 5a of a cultivated field 5 and forms banking lateral to a side a front face plate 33 which regulates the rearward movement of tilled soil a swinging plate 35 which acts on the surface of the formed banking to form the ridge slope and has a swinging fulcrum at the lower part a beating plate 37 which beats and compacts the surface of the formed ridge slope a power transmission mechanism which simultaneously actuates the tilling rotary 31, the swinging plate 35 and the beating plate 37 and a movable frame 41 which is rotationally connected to a traction frame 19 of a traveling vehicle and integrally supports the various members wherein a mounting angle of the front plate 33 to the movable frame 41 in tilling work is so set as to take a rearward-tilted attitude tilted rearward by a rearward-tilted angle &theta.COPYRIGHT: (C)2012,JPO&INPIT【課題】耕耘ロータリー直後の土溜まりを防止して円滑な畦付けと、良好で固着力の強い畦法面の成形とを可能にする。【解決手段】畦付け機1は、耕作地5の地面5aを掘削し、側部外方に盛り土を形成する耕耘ロータリー31と、耕耘土の後方への移動を規制する前面板33と、形成した盛り土の表面に作用して畦法面を成形する揺動支点を下方に備えた揺動板35と、成形された畦法面の表面を叩いて押し固める叩き板37と、前記耕耘ロータリー31と揺動板35と叩き板37とを同時に駆動する動力伝達機構と、走行車両の牽引フレーム19に対して回動自在に接続され、前記諸部材を一体に支持する可動フレーム41と、を具備し、前記可動フレーム41に対する前面板33の取付け角度を耕耘作業時において、後傾角度θ分、後方に傾いた後傾姿勢になるように設定している。【選択図】図3
