The invention relates to a grab bucket special for ball-like objects. The grab bucket comprises a mounting disc. The upper end face of the mounting disc is symmetrically provided with two pairs of lifting lugs. Four supporting columns are symmetrically welded to the two sides of the lower end face of the mounting disc. The tail ends of the four supporting columns are provided with four mounting circular rings respectively. The four mounting circular rings are arranged on four rotating shafts through bearings respectively. The four rotating shafts are fixedly arranged on two grabbing branch chains opposite to each other. Two lug bases are symmetrically welded to the two sides of the lower end face of the mounting disc. Two first hydraulic cylinders are arranged on the two lug bases through pin shafts respectively. Telescopic rods of the two first hydraulic cylinders are arranged on two sleeves through threads respectively. The two sleeves are arranged on two supporting blocks through bolts respectively. The sleeves are used for connecting the first hydraulic cylinders and the corresponding supporting blocks. The two supporting blocks are symmetrically welded to the two grabbing branch chains. By means of the grab bucket, ball-like objects can be carried quickly, and the grab bucket has the beneficial effects of being easy and convenient to operate, high in working efficiency, wide in application range and the like.
