Underwater hydraulic claw bucket suitable for torrent area

The invention discloses an underwater hydraulic grab bucket which is suitable to rapid flow waters, which comprises a bucket rod, a bucket body and a hydraulic cylinder, and further comprises a cross suspension device and an anti-floating device. The bucket body can slant a certain angle along the horizontal and longitudinal directions when the cross suspension device of the invention is acted with the effect of water flow impact or in the gyroscopic motion of loading and unloading mud, which avoids the bucket rod from bearing enormous bending moment, and reduces the fault rate on the joint portion of the bucket rod and the hydraulic grab bucket. And the anti-floating device can limit the slanting angle of the bucket body over large under the water flow impact, avoids the phenomenon of over-large bucket floating or horizontal bucket, and increases the working efficiency of digging.
