PROBLEM TO BE SOLVED: To provide a levee-plastering machine capable of forming scarcely breaking, compact and new levee.SOLUTION: The levee-plastering machine 11 includes a digging means 13 for digging a base levee and a levee-forming means for forming a new levee B by pressing dug soil. The digging means 13 has a rotational shaft 31 which is parallel to slant levee side of a base levee A and slant to vertical direction when viewed from the side. A plurality of digging claws 32 for digging levee side of the base levee A by rotating these claws together with the rotational shaft 31 are installed in the rotational shaft 31. Whole the levee side of the base levee A is dug by a plurality of digging claws 32 and uneven parts each composed of a plurality of recessed arc faces which are mutually continued to the levee side of the base levee A are formed thereby. Dug soil on each recessed arc face of the uneven part is pressed by the levee-forming means 14 to form the levee side of the new levee.COPYRIGHT: (C)2009,JPO&INPIT【課題】崩れにくい締まった新畦を形成できる畦塗り機を提供する。【解決手段】畦塗り機11は、元畦Aを掘削する掘削手段13と、掘削土を押圧して新畦Bを形成する畦形成手段14とを備える。掘削手段13は、元畦Aの傾斜状の畦側面に対して平行状でかつ側面視で上下方向に対して傾斜状の回転軸31を有する。回転軸31には、この回転軸31とともに回転して元畦Aの畦側面を掘削する複数の掘削爪32を設ける。複数の掘削爪32にて元畦Aの畦側面の全体を掘削し、その元畦Aの畦側面に互いに連続した複数の凹弧面からなる凹凸状部を形成する。この凹凸状部の各凹弧面上の掘削土を畦形成手段14で押圧して新畦の畦側面を形成する。【選択図】図1
