Large-scale nodule collector for multi-metal nodules on deep sea floor

Abstract

The invention discloses a large-scale nodule collector for multi-metal nodules on a deep sea floor. The large-scale nodule collector comprises a traveling chassis, a rack, a nodule collection box, nodule collection rollers, a roller support, a mechanical tooth type conveying belt and a power driving system. The rack is fixed to the traveling chassis. The nodule collection box is fixed to the rack. The nodule collection rollers are mounted on the rack through the roller support and located at the front end, in the advancing direction, of the whole nodule collector. The mechanical tooth type conveying belt is arranged between the nodule collection rollers and the nodule collection box. Collection teeth are arranged on the nodule collection rollers and used for digging up the multi-metal nodules and then conveying the multi-metal nodules onto the mechanical tooth type conveying belt. The front end of the mechanical tooth type conveying belt conveys the multi-metal nodules into the nodule collection box from bottom to top. The power driving system drives the traveling chassis, the nodule collection rollers and the mechanical tooth type conveying belt to move. According to the large-scale nodule collector for the multi-metal nodules on the deep sea floor, the arc-shaped mechanical tooth type nodule collection rollers are used for combined work, so that the ore collection efficiency and recovery rate are greatly improved; and the whole nodule collector can automatically adapt to the terrain change of the sea floor under the effect of a nodule collection roller terrain clearance adjustment oil cylinder and an adjustment frame.

Description

technical field [0001] The invention relates to a large-scale ore collecting machine for deep seabed polymetallic nodules. Background technique [0002] With the increasing scarcity of terrestrial mineral resources and the continuous deepening of human understanding of the ocean, the extremely rich mineral resources in the deep sea have increasingly attracted widespread attention from the international community, and are considered to be the most important replacement resources for human beings in the 21st century. Deep seabed polymetallic nodules are the earliest solid mineral resources discovered on the seabed and evaluated to have the most commercial exploitation value. They occur in water depths of 4000-6000m, and they occur in the seabed sediments in the form of round or elliptical particles with a particle size of 2-10cm. surface layer. Since the distribution form and occurrence state are completely different from other two major seabed solid mineral resources such as...
