PROBLEM TO BE SOLVED: To provide a levee plastering machine by which the wear of a slope blade plate is reduced while keeping the effects for smoothening the slope of the levee, and in which a levee slope-smoothening body having a strength against the weight is installed.SOLUTION: The figures express partial cross-sections representing positional relationships between contact extension lines Ma, Mb, and Mc, and a ring member 40 at the position from an extension part 22 of the slope blade plate 21 to a lower stage 23. The ring member 40 is positioned on the opposite side of a contact surface MS of the slope blade plate 21 based on the contact extension lines Ma, Mb, and Mc extended from the contact surface MS on the contact side of the slope blade plate 21 with the levee slope surface 70b over the position from the extension part 22 in the arc part 25 of the slope blade plate 21 to the lower stage 23.COPYRIGHT: (C)2013,JPO&INPIT【課題】畦法面の整畦の効果を維持しつつ、法面羽根板の摩耗を低減させ、さらに、重量に対する強度を備えた法面整畦体を搭載する畦塗り機を提供する。【解決手段】法面羽根板21の張出部22から下段部23における接触延長線Ma、Mb及びMcと、リング部材40との位置関係を示す部分断面図であり、リング部材40は、法面羽根板21の円弧部分25における張出部22から下段部23に亘って、法面羽根板21の畦法面70bに接触する側の接触面MSから延びる接触延長線Ma、Mb及びMcに対して、法面羽根板21の接触面MSとは反対側に配置する。【選択図】図7
