PROBLEM TO BE SOLVED: To provide a ground leveling device capable of preventing ground-leveling width from decreasing as component members of a ground-leveling rotor overlap, because the component members resist wear even if used over a long period of time.SOLUTION: Ground-leveling plates 5 are arranged at predetermined intervals on the rotating outer peripheral portion of a disk plate 4 having at its center both a boss hole 2 through which a rotor shaft 1 is passed and a rotor boss 3 thereof. The ground-leveling plate 5 is formed to protrude horizontally outwards so as to be wider than the width of the rotor boss 3 and the thickness of the disk plate 4. A rib 6 which protrudes by an appropriate thickness at the position of a lateral end on the back side with respect to the direction of rotation is formed, and the center portion of the horizontal width of the ground-leveling plate 5 is secured to the outer peripheral edge 7 of the disk plate 4, to form a unit ground-leveling rotor 8. A plurality of unit ground-leveling rotors 8 are mounted along the direction of the rotor shaft 1. The ground-leveling rotors 8 are journaled in such a way as to rotate while the phases of the ground-leveling plates 5 between rotor component members forming each of the ground-leveling rotors 8 being adjacent to each other horizontally are moved with respect to each other longitudinally.COPYRIGHT: (C)2013,JPO&INPIT【課題】長期間に亘って使用しても整地ロータの構成部材が摩耗しにくく、構成部材同士が重なり合って整地幅が短くなることを防止できる整地装置を提供する。【解決手段】ロータ軸1を挿通するボス穴2、及びこのロータボス3を中心部に有したディスクプレート4の回転外周部に所定間隔毎に整地板5を配置し、整地板5は、ロータボス3の幅及びディスクプレート4の厚さよりも左右外側方向へ幅広く突出させて形成し、回転方向に対する裏面側で且つ横端位置に適宜厚さ分突出するリブ6を形成し、整地板5の左右方向幅の中央部をディスクプレート4の外周縁7に固着して単位整地ロータ8を構成し、単位整地ロータ8複数箇をロータ軸1の方向に沿って装着し、左右に相隣接する整地ロータ8を構成するロータ構成部材の相互間の整地板5の位相を前後にずらした形態で回転するよう軸装して構成する。【選択図】 図1
