Spraying assembly of high-pressure water descaling device for forge pieces

The invention discloses a spraying assembly of a high-pressure water descaling device for forge pieces. The spraying assembly comprises a spraying box, wherein two vertical spraying pipes are oppositely arranged in the spraying box, a plurality of nozzles are arranged on the spraying pipes at intervals in the length direction of the spraying pipes, the positions of the nozzles on the two spraying pipes are in one-to-one correspondence, a spraying operation space is formed between the two spraying pipes, and the spraying pipes are connected with a high-pressure water pipe. The spraying assembly further comprises a transverse rod horizontally arranged in the spraying box, wherein a first sliding groove is formed in the transverse rod in the length direction of the transverse rod, and the upper portions of the spraying pipes are clamped in the first sliding groove and can rotate and move in the first sliding groove so as to adjust the distance between the two spraying pipes and the angles of the nozzles at the c
