PROBLEM TO BE SOLVED: To provide a grab bucket in which the roughing work of a water bottom and the leveling work for flatly leveling an uneven part after the roughing can be performed only in one grab bucket, and a series of work from the roughing work to the leveling work for flatly leveling an uneven part can efficiently be performed in a short time.SOLUTION: A grab bucket is targeted which includes an upper frame 1, a lower frame 2, a bucket shell 4 and a rod 5, etc., and each bucket shell 4 has a bottom wall 17, a front wall 18 and a back wall 19. A leveling tool S for leveling an uneven water bottom is mounted in each of the excavation back surface of the bottom wall 17 of each bucket shell 4 in a closing state. In the state where the pair of bucket shells 4 is closed, a closing portion between the leveling tool S and the pair of bottom walls 17 is cooperated to level the water bottom after the roughing. According to this, the roughing work of the water bottom can be performed without the leveling tool S interfering with the opening and closing operation of the bucket shell 4. Also, the water bottom is pressed with the leveling tool S and the pair of bottom walls 17, and the water bottom after the roughing can be leveled.SELECTED DRAWING: Figure 1
【課題】水底面の荒掘作業と、荒掘後の凹凸部を平坦に均す均し作業とを１個のグラブバケットのみで行うことができ、また、荒掘作業から、凹凸部を平坦に均す均し作業に至る一連の作業を、短時間で能率よく行えるグラブバケットを提供する。【解決手段】上フレーム１、下フレーム２、バケットシェル４、およびロッド５などを備え、各バケットシェル４が、底壁１７、前壁１８、および後壁１９を有するグラブバケットを対象とする。閉じ状態における各バケットシェル４の底壁１７の掘削背面のそれぞれに、凹凸状の水底面を均す均し具Ｓを装着する。一対のバケットシェル４が閉じた状態において、均し具Ｓと一対の底壁１７の閉合部分が協同して、荒掘後の水底面を均す。これによれば、均し具Ｓがバケットシェル４の開閉動作の邪魔になることなく、水底面の荒掘作業を行える。また、均し具Ｓと一対の底壁１７とで水底面を押圧して、荒掘後の水底面を均すことができる。【選択図】図１
