PROBLEM TO BE SOLVED: To provide a ridge plastering machine which forms a flat ridge top with even height.SOLUTION: The ridge plastering machine includes a soil-heaping part which heaps up soil and a ridge-top-former 5 which fastens and hardens the heaped soil prepared by the soil-heaping part and forms a horizontal plane-like ridge top. The ridge-top-former 5 is equipped with a ridge-top-forming member 81 that rotates around the axis d of eccentric rotation, which moves to draw a circle around a standard central axis c, and fastens and hardens the heaped soil to form the ridge top. The ridge-top-forming member 81 forms a periphery of an approximately polygonal shape from a side view. During a ridge-forming operation, a vertical distance between the standard central axis c and the lower end position of the ridge-top-forming member 81 is approximately constant.COPYRIGHT: (C)2012,JPO&INPIT【課題】高さの安定した平坦な畦上面を形成できる畦塗り機を提供する。【解決手段】畦塗り機は、土を盛り上げる盛土体と、盛土体による盛土を締め固めて水平面状の畦上面を形成する畦上面形成体5とを具備する。畦上面形成体5は、基準中心軸線cを中心として円を描くように移動する偏心回転中心軸線dを中心として回転しながら、盛土を締め固めて畦上面を形成する上面形成部材81を備える。上面形成部材81は、側面視で略多角形状をなす外周形状に形成する。畦形成作業時には、基準中心軸線cと上面形成部材81の下端位置との垂直距離が略一定である。【選択図】図15
