ABSTRACT:
An apparatus for continuously dredging submarine mineral deposit comprising plural pairs of pulleys, each of which is pivoted coaxially at a preset distance. Plural pairs of specific endless ropes are adapted to be brought into contact with said pulleys and to be driven in translation movement with each other. Means is provided for preventing slippage between said ropes. When buckets for scraping up ores are being circulated between the upper deck of a barge and the seabed, said endless ropes are directed to travel downward from the upper part in a diagonally rearward direction. Also provided is an ore discharging chute adjacent to a spot where each of said buckets begins to glide down.
