PROBLEM TO BE SOLVED: To provide a ridge forming machine which can expand an adjustment height of ridge forming, correspond to working conditions such as characteristics of district, climate, and soil and high ridge in recent years, and improve flexibility of the ridge forming.SOLUTION: In a ridge forming machine, a rotation axis P1 of a lower rotary ridge forming body 13 is arranged to be inclined upward by a prescribed angle θ from a lateral side of one side face W2 of a ridge W to the ridge side. A rotation axis P2 of an upper rotary ridge forming body 14 is arranged to be inclined downward by a prescribed angle α from an upper side of the lower rotary ridge forming body to a top face W1 of the ridge. A rotation board member 14e is arranged in the upper rotary ridge forming body along a periphery of the lower rotary ridge forming body, and a height adjusting mechanism 17 is arranged performing vertical motion of the upper rotary ridge forming body along the periphery of the lower rotary ridge forming body.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】整畦高さの調節幅を拡大することができ、地域、天候、土壌の性質等の作業条件や近年の高畦作業に対応することができ、整畦作業の融通性を高めることができる。【解決手段】下部回転整畦体13の回転軸線P1は上記畦Wの一方側面W2の側方から畦側へ斜め上方に向かう所定角度θの上向き方向に配置され、上記上部回転整畦体14の回転軸線P2は上記下部回転整畦体の上方から畦の上面W1に向かう所定角度αの下向き方向に配置され、上記上部回転整畦体に上記下部回転整畦体の外周部に沿う形状の回転盤部材14eを設け、上部回転整畦体を上記下部回転整畦体の外周部に沿う方向に上下動作させる高低調節機構17を設けてなる。【選択図】図5
