The invention discloses a novel hydraulic sludge grab bucket which comprises two bucket parts which are oppositely arranged and can be opened and closed. One end of each conveying supporting rod device is hinged to the position of the rear portion of an upper top plate of the corresponding bucket part, and the other ends of the conveying supporting rod devices are hinged to an upper connecting block. A push oil cylinder is fixed to the top face of the middle portion of the upper connecting block. A pushing rod of the push oil cylinder penetrates the upper connecting block downwards and is fixedly provided with a push block. Push rods are arranged at the lower portion of the push block. The upper ends of the two push rods are hinged to the bottoms of the two ends of the push block. The other ends of the push rods are hinged to the positions of the front portions of the upper top plates of the bucket parts. The end faces, in contact with each other, of the two bucket parts are fixedly provided with buffering layers, and the two buffering layers abut against each other. The two bucket parts of the novel hydraulic sludge grab bucket are not liable to be impacted and damaged, the protection effect is good, the bucket parts are closed and opened by adopting the single push oil cylinder, the novel hydraulic sludge grab bucket is simple in structure and good in effect, and the two bucket parts can be closed firmly by adopting a permanent magnet block and a permanent magnet layer.
