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
