PROBLEM TO BE SOLVED: To perform levee-shaping work for an unshaped levee part of a levee caused by a machine length of a traveling machine body by moving forward and backward a levee-shaping mechanism by a reciprocally moving mechanism while driving the levee-shaping mechanism.SOLUTION: In this levee-shaping machine, a machine frame 3 is connected to the traveling machine body 1 by a connecting mechanism 2, and one side part of the machine frame is provided with the levee-shaping mechanism 4 having a rotary levee-shaping body 5 capable of rotatively levee-shaping a levee W-shaped surface. In order to perform levee-shaping work for an unshaped levee part T caused by the machine length of the traveling machine body, the levee-shaping mechanism is disposed to freely reciprocally move in the advancing direction of the levee-shaping work by a guide mechanism 6 at the side of the traveling machine body, a reciprocally moving mechanism 7 for reciprocally moving the levee-shaping mechanism is provided, and the reciprocally moving mechanism uses a feed screw mechanism 8 including a feed screw shaft 8a and a feed nut 8b.COPYRIGHT: (C)2013,JPO&INPIT【課題】整畦機構を駆動しながら往復移動機構により整畦機構を前進移動させることにより、走行機体の機長により生ずる畦の未整畦部の整畦作業を行うことができる。【解決手段】走行機体1に連結機構2により機枠3を連結し、機枠の一方側部に畦W面を回転整畦可能な回転整畦体5をもつ整畦機構4を設けてなり、走行機体の機長により生ずる畦の未整畦部Tの整畦作業を可能とするため、整畦機構を走行機体の側方位置において案内機構6により整畦作業進行方向に往復移動自在に配設し、整畦機構を往復移動させる往復移動機構7を設け、往復移動機構は送りねじ軸8a及び送りナット8bからなる送りねじ機構8が用いられている。【選択図】図1
