PROBLEM TO BE SOLVED: To provide a levee-plastering machine equipped with a pre-treating part which is hardly damaged, is excellent in soil-crushing performance, and has a large ridging effect.SOLUTION: The levee-plastering machine equipped with a pre-treating part 61 which is mounted on a travel machine frame, is disposed at a position off-set on the side of a travel position, cuts through an old levee, and piles soil, and with a levee-forming part for coating the cut-through old levee with the piled soil, and travelling with the travel of the travel machine frame to perform a levee-plastering work, is characterized in that the pre-treating part 61 has a rotatably supported tillage shaft 62 extended in the travel direction, tillage tines 67 disposed on the tillage shaft, and scooping tines 69 disposed on the tillage shaft 62 to pile the soil tilled with the tillage tines 67 on the oil levee the scooping tines 69 each has a scooping plate 69b for scooping up the soil on the tip part the scooping plate part 69b is disposed on the rotation rear side in the action region 68 of the tillage tine 67 and the tip part of the tillage tine 67 and the tip part of the scooping plate part 69b are arranged at close positions on the axial direction view of the tillage shaft 62.COPYRIGHT: (C)2012,JPO&INPIT【課題】損傷しにくく砕土性能に優れて土寄せ効果が大きい前処理部を備えた畦塗り機を提供する。【解決手段】畦塗り機は、走行機体に装着され、この走行位置に対して側方にオフセットした位置に配置され、旧畦を切り崩して土盛りを行う前処理部61と盛られた土を切り崩された旧畦上に塗り付ける整畦部を備え、走行機体の走行とともに進行して畦塗り作業を行う。前処理部61は、進行方向に沿って延びて回転自在に支持された耕耘軸62と、この軸に設けられた耕耘爪67と、耕耘軸62に設けられ耕耘爪67によって耕耘された土を旧畦側に土盛りする掬い爪69を有する。掬い爪69は、その先端部に土を掬い上げる掬い板部69bを有し、掬い板部69bは耕耘爪67の作用域68の回転後方側に配置され、耕耘爪67の先端部と掬い板部69bの先端部は耕耘軸62の軸方向矢視において接近した位置に配置される。【選択図】 図1
