The utility model discloses a seabed many metal sulfides ore deposit digging device, including sitting end frame, vertically move about frame, transversely move about frame and the system of excavating, it has the two sets of of parallel arrangement to sit end frame, the frame of transversely moving about connect in at the bottom of two seats between the frame, vertically move about the frame andconnect in the frame of transversely moving about, the frame of vertically moving about can be followed the frame of transversely moving about and remove and change its lengthwise position, the frameof transversely moving about can remove and changes its horizontal position for sitting end frame, the connection that the system of excavating can stretch out and draw back from top to bottom is in the frame of vertically moving about, the removal of the frame of vertically moving about makes the exploitation of excavating the head and realizing following ore body length direction, and the removal messenger of the frame of transversely moving about excavates the head and realizes along ore body width direction's exploitation, vertically and transversely excavates the regional exploitation ofthe whole ore body of completion through a lot of. It can be in steady walking in rugged and rough ore body surface and the advantage that can effectively excavate the widely different ore body in part to have.
