PROBLEM TO BE SOLVED: To provide a levee-plastering machine equipped with a pretreatment part that has a soil gathering function, superior soil crushing properties and hardly causes large vibrations even if brought into contact with an obstacle.SOLUTION: A levee-plastering machine is arranged in an offset position of the side of a traveling machine and includes a pretreatment part 61 and a levee-shaping part 80. The pretreatment part 61 has a first tilling tine 67, a second tilling tine 69 and a third tilling tine 70 arranged in a plurality of rows on a rotatably supported tilling shaft 62 at prescribed intervals in the shaft center direction. These tilling tines have longitudinal blade parts and lateral blade parts continuously extended from a mounting base and are bent from the longitudinal blade parts to the lateral blade parts in a direction opposite to the rotation direction of the tilling shaft and the lateral blade parts are bent to one side relative to the longitudinal blade parts. The lateral blade part 67c of the first tilling tine 67 at the end of the row of the tilling tines is bent toward the front side in the shaft center direction of the tilling shaft 62, the lateral blade part 69c of the second tilling tine 69 at the front row side from the end of the row is bent toward the rear side and these tilling tines are arranged at approximately equal intervals in the peripheral direction of the tilling shaft 62.COPYRIGHT: (C)2014,JPO&INPIT【課題】土寄せ機能を有して砕土性が良く、傷害物に接触しても大きな振動が生じにく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、走行機体の側方のオフセットした位置に配置され、前処理部61及び整畦部80を備える。前処理部61は、回転自在に支持された耕耘軸62に軸芯方向に所定間隔を有して複数列に設けられた第1耕耘爪67,第2耕耘爪69,第3耕耘爪70を有する。これらの耕耘爪は、この取付基部から連続して延びる縦刃部、横刃部を有し、縦刃部から横刃部にかけて耕耘軸の回転方向と逆向きに弯曲し、且つ横刃部が縦刃部に対して一側方へ弯曲する。耕耘爪のうち最後列の第1耕耘爪67の横刃部67cは、耕耘軸62の軸芯方向前側へ向いて屈曲し、最後列より前列側の第2耕耘爪69の横刃部69cは後方側へ向いて屈曲し、これらの耕耘爪は、耕耘軸62の周方向に略等間隔を有して配設される。【選択図】図3
