PROBLEM TO BE SOLVED: To improve strength and rigidity of a structure of an agitator having an agitating rotor mounted thereon and an interlocking configuration for driving the agitating rotor, to maintain high durability by facilitating application of agitating pressure to concrete, and to improve operability, in consideration that excessive load easily acts on the agitating rotor that agitates kneaded concrete.SOLUTION: The agitator includes a working machine main frame having: a machine body 1 and a motor 2 mounted on the machine body 1, the motor 2 driving the working machine main frame. The working machine main frame has: a tilling shaft 3 to which tilling rotors are mounted and operation handles 4 jutting toward a rear upper part of the machine body 1. The working machine main frame can be operated based on this construction. In the working machine main frame, an interlock case 7 housing an interlock mechanism 6 which transmits driving power from the tilling shaft 3 to a rear-lower-position rotor-shaft 5 is attached being directed toward a rear-lower-position of the tilling shaft 3 in the working machine main frame operable for tilling work, and agitating (tilling) rotors 8 are attached to the rotor shaft 5 jutting to laterally both sides of the interlock case 7.COPYRIGHT: (C)2012,JPO&INPIT【課題】 練込みコンクリートの撹拌を行う撹拌ロータには、過大の負荷が働き易く、この撹拌ロータを取付ける撹拌機の構成、及び撹拌ロータを駆動する連動構成等の強度、剛性を高く構成し、又、コンクリートに対する撹拌押圧力をかけ易くして耐久性を高く維持し、操作性をを良くすることが必要である。【解決手段】 機体1に搭載の原動機2によって駆動すると共に、耕耘ロータを装着可能とする耕耘軸3と、この機体1の後方上部に張出の操作ハンドル4を有して耕耘作業可能の作業機本体に、前記耕耘軸3の後方下部位置に向けて、この耕耘軸3から後下端部のロータ軸5を伝動する連動機構6を内装する連動ケース7を取付けて、この連動ケース7の左右両側部に張出すロータ軸5に撹拌ロータ8を取付ける。【選択図】 図1
