PROBLEM TO BE SOLVED: To provide a ridge forming machine for performing ridge forming work with an excellent finished state without being affected by a type of soil of a farm field and a ridge and a weather condition in the ridge forming work by performing the ridge forming work with pressing plates with different degrees of rigidity from each other since a plurality of the pressing plates comprise several kinds of plate materials having different degrees of rigidity from each other to obtain the pressing plates having differences, for example, in elastic moduli, ways of bending, and strength of the pressure contact degree with the ridge.SOLUTION: A filling mechanism 4 for filling soil on an old ridge W is provided on a machine casing 3. A ridge forming mechanism 12 having a rotational ridge forming body 13 capable of rotating and forming a ridge on a ridge surface by rotating with pressure contact is provided in a position in the back of the filling mechanism in a travelling direction. A plurality of pressing face bodies K.. are disposed at intervals on a peripheral part of the rotational ridge forming body. A flexible and elastic pressing plate G which extends from a pressing face body side in a front position in the rotating direction to a pressing face part K1 of the adjacent pressing face body in a rear position is provided on each pressing face body. The plurality of the pressing plates comprise several kinds of plate materials having different degrees of rigidity from each other.COPYRIGHT: (C)2016,JPO&INPIT【課題】複数個の圧締板体は相互に剛性が大小に異なる数種類の板材からなるので、例えば、圧締板体の弾性率、撓み方、畦の圧接度合いの強弱が相互に異なる圧締板体を得ることができ、相互に剛性の異なる圧締板体で整畦作業を行うことにより、圃場及び畦の土質、整畦作業時の気象条件にそれほど影響されることなく、良好な仕上状態となる整畦作業を行うことができる。【解決手段】機枠３に旧畦Ｗ上に土を盛り上げる盛土機構４を設け、盛土機構の進行方向後方位置に畦面を圧接回転により回転整畦可能な回転整畦体１３をもつ整畦機構１２を設け、回転整畦体の外周部分に複数個の圧締面体Ｋ・・を間隔を置いて配設すると共に各々の圧締面体に回転方向前方位置の圧締面体側から隣り合う後方位置の圧締面体の圧締面部Ｋ１に至る可撓弾性をもつ圧締板体Ｇを配設してなり、複数個の圧締板体は相互に剛性が大小に異なる数種類の板材からなる。【選択図】図８
