PROBLEM TO BE SOLVED: To provide a levee-plastering machine that performs a levee crown treatment of a high levee and raises a levee crown treatment part to an upper position of a levee crown of old levee in a levee crown non-treatment.SOLUTION: The levee-plastering machine includes an operation part having a levee crown treatment part 11 for cutting through a levee crown of an old levee, a pretreatment part 30 for cutting through an old levee and building up soil and a levee-plastering part for plastering the old levee which is cut through with built up soil. The levee crown treatment part 11 is supported at the tip part of a levee crown power transmission case 20 that has a rotary fulcrum Po coaxially on a tilling shaft 34 of the pretreatment part 30 and is rotatable in the vertical direction and is adjustable in the vertical position by a vertical position adjustment mechanism part 60 connected to between the levee crown treatment part 11 and a support frame mounted on the operation part. The vertical position adjustment mechanism part 60 is adjustable in length and a swinging fulcrum Py of the vertical position adjustment mechanism part is changeable in position by a position change mechanism part 70 at the end part of the vertical position adjustment mechanism part.COPYRIGHT: (C)2012,JPO&INPIT【課題】高い畦の天場処理ができ、また非天場処理時に旧畦の天場の上方位置に天場処理部を跳ね上げ可能な畦塗り機を提供する。【解決手段】畦塗り機は、旧畦の天場を切り崩す天場処理部11と、旧畦を切り崩して土盛りを行う前処理部30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とを有する作業部を備える。天場処理部11は前処理部30の耕耘軸34と同軸上に回動支点Poを有して上下方向に回動自在な天場動力伝達ケース20の先端部に支持されるとともに、天場処理部11と作業部に設けられたサポートフレームとの間に接続された上下位置調整機構部60によって上下位置調整が可能である。上下位置調整機構部60は長さ調整が可能であり、その他端部は位置変更機構部70によってその揺動支点Pyが位置変更可能である。【選択図】 図6
