The invention belongs to the technical field of electric hydraulic grab buckets, and particularly relates to a grab bucket which comprises a lifting table, a plurality of spherical grab bucket claws are movably mounted below the lifting table, two arc-shaped pieces are fixedly mounted on the side edge of each spherical grab bucket claw, and a plurality of supporting rods are movably mounted on the outer side of a hydraulic head. A spacing groove is formed between every two adjacent arc-shaped pieces, an arc-shaped oil bag is fixedly mounted at the inner top of each spacing groove, and when the multiple spherical grab buckets rotate to be in a closed state, the lower ends of the supporting rods can extrude the arc-shaped oil bags, so that the arc-shaped oil bags deform; when the outer sleeve is in use, lubricating oil stored in the arc-shaped oil bag can enter the fixing shaft along the first elastic pipe and the second elastic pipe, an oil groove can be formed in the fixing shaft, the oil entering the fixing shaft flows to the distance between the fixing shaft and the outer sleeve, and then the fixing shaft and the outer sleeve are lubricated.
本发明属于电动液压抓斗技术领域,具体的说是一种抓斗,包括升降台,升降台的下方活动安装有多个球体抓斗爪,每个的球体抓斗爪侧边均固定安装有两个弧形件,液压头的外侧活动安装有多个支撑杆,两个相邻的弧形件之间开设有间距槽,间距槽的内顶部固定安装有弧形油囊,通过多个球体抓斗转动成关闭状态时,支撑杆的下端会对弧形油囊进行挤压,进而使得弧形油囊进行形变,弧形油囊内部存储的润滑油就会顺着第一弹性管和第二弹性管进入到固定轴内部,在固定轴内可以设置油的槽,让进入固定轴内部的油流淌到固定轴和外套筒的间距处,进而对固定轴和外套筒进行了润滑。
