PROBLEM TO BE SOLVED: To provide a levee shaper of a levee-plastering machine, which can simplify constitution associated with attachment and detachment and can easily and quickly perform attachment and detachment operation without requiring a new tool in attachment and detachment of a levee shaping part of an upper surface corresponding to the levee height.SOLUTION: When a levee shaping part 30 of an upper surface is covered with a levee shaping part 40 of a covered upper surface, an inside face of a side 43 of the levee shaping part 40 of the covered upper surface includes an approximately circle-shaped guide member 45 for keeping an interval from a side wall surface 34 of the levee shaping part 30 of the upper surface in the peripheral direction and an interval between the inside face of the side 43 of the levee shaping part 40 of the covered upper surface and the side wall surface 34 of the levee shaping part 30 of the upper surface is kept constant. Here, a top surface 41 of the levee shaping part 40 of the covered upper surface has a hook member 42 for fixing a position relationship between the top surface 41 and a top wall surface 31. When the levee shaping part 40 of the covered upper surface is moved in a state in which the levee shaping part 30 of the upper surface is covered with the levee shaping part of the covered upper surface, a levee-plastering machine is equipped with an engagement edge part 38 to be engaged with the hook member 42 of the levee shaping part 40 of the covered upper surface.COPYRIGHT: (C)2014,JPO&INPIT【課題】畦の高さに対応した上面整畦部の着脱に際し、新たな工具を必要とすることなく、また、着脱に係る構成を簡易にし、容易かつ迅速に着脱作業を行うことができる畦塗り機の整畦体を提供する。【解決手段】被覆上面整畦部40を上面整畦部30に被せた場合に、被覆上面整畦部40の側面43の内側面に、上面整畦部30の側壁面34との間隔を周方向に向けて一定に保つ略円環状のガイド部材45が設けられており、被覆上面整畦部40の側面43の内側面と上面整畦部30の側壁面34との間隔を一定に保つ構成としている。ここで、被覆上面整畦部40の頂面41には、頂面41と頂壁面31との位置関係を固定するフック部材42が設けられている。そして、被覆上面整畦部40を上面整畦部30に被せた状態のまま移動した際に、被覆上面整畦部40のフック部材42が係合する係合縁部38が備わっている。【選択図】図10
