PROBLEM TO BE SOLVED: To provide a levee plastering machine capable of scraping always a fixed amount of a top place of an old levee regardless of the state of a farm field.SOLUTION: A levee plastering machine 1 includes a top place treatment part 40 arranged on a sideward off-set position with respect to the traveling position of a traveling machine body, for cutting through the top place of an old levee to the moving end side of an off-set mechanism part provided rotatably rightward/leftward with respect to a traveling direction. The top place treatment part 40 is supported movably in the vertical direction by the off-set mechanism part. The levee plastering machine 1 is provided with a hydraulic cylinder 33 for moving the top place treatment part 40 in the vertical direction, a position detection sensor 80 for detecting a vertical position of the upper surface of the old levee with respect to the top place treatment part 40, and a control part for adjusting the vertical position of the top place treatment part 40 by controlling operation of the hydraulic cylinder 33 in accordance with a detection value of the position detection sensor 80 so that the depth of the top place of the old levee to be scraped by the top place treatment part 40 becomes constant.COPYRIGHT: (C)2014,JPO&INPIT【課題】圃場の状況に拘わらずに常に旧畦の天場を一定量削ることができる畦塗り機を提供する。【解決手段】畦塗り機1は、走行機体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、進行方向に対して左右方向に回動自在に設けられたオフセット機構部の移動端側に旧畦の天場を切り崩す天場処理部40を備える。天場処理部40はオフセット機構部に上下方向に移動自在に支持される。畦塗り機1には、天場処理部40を上下方向に移動させる油圧シリンダ33と、天場処理部40に対する旧畦の上面の上下位置を検出する位置検出センサ80と、天場処理部40により削られる旧畦の天場の深さが一定になるように位置検出センサ80の検出値に応じて油圧シリンダ33の作動を制御して天場処理部40の上下位置を調整する制御部が設けられる。【選択図】 図3
