Description
Technical Field
The invention belongs to the technical field of submarine mineral resource exploitation equipment, and particularly relates to hydraulic-mechanical combined rock breaking equipment suitable for the seabed.
Background
Oceans account for approximately 71% of the surface area of the earth, and there are a large number of various mineral resources that have not been fully recognized and utilized by humans. With the rapid development of world industry and economy, mineral resources on land are in short supply, and the demand of human beings on the mineral resources is increased sharply, so people turn the attention to the sea. The deep sea mineral resources have a plurality of rare and precious metal elements and have great commercial development potential. There are almost all kinds of resources on land in the ocean, and some resources not on land, and the deep sea bottom contains various mineral resources such as coal mine, iron ore, seashore placer, polymetallic nodule, cobalt-rich crust, polymetallic sulfide and the like. The multi-metal nodule and the cobalt-rich crust are rich in metals such as manganese, cobalt, nickel, copper and the like, the storage capacity of the metals is dozens of times to thousands of times of the corresponding storage capacity of the land, and the metals are important strategic resources and are widely applied to the chemical industry and the high-tech production.
Mineral resources in the ocean are typically distributed in deep ocean depths below 200 meters, and mining of these resources presents significant challenges. The deep sea mining method is characterized in that mineral resources in the sea are efficiently and safely transported to the sea surface through corresponding technical means and equipment, and are transported to the land after being primarily processed. Depending on the mining method, it is largely divided into 4 types of mining systems, respectively, a trawler mining system, a continuous bucket lift mining system, a shuttle car mining system, and a pipe lift mining system, of which the pipe lift mining system is considered by many countries as the most promising commercial mining system. The key technology of the pipe-type elevating mining system is the crushing and collecting of minerals. The method is difficult to collect mineral resources such as cobalt-rich crusts and sulfide ores on the surface of the seabed, wherein the cobalt-rich crusts exist in the water depth of 800-3000 m and are in a plate shape or a gravel shape. The thickness of the artificial sea wall is generally several millimeters to tens of millimeters, and the artificial sea wall covers the bedrock on the sea bottom. Therefore, in order to collect mineral resources such as cobalt-rich crusts and sulfide ores, simple, efficient and safe rock breaking equipment needs to be designed, so that the efficiency of deep sea mining is improved.

When the breaking drill rod 10-1 rises to the highest point of the stroke, the upper end of the reversing valve is attracted, hydraulic oil enters the rodless cavity of the cylinder body 10-3 through the oil inlet pipe 22 of the breaking hammer, the breaking drill rod 10-1 moves downwards under the action of hydraulic pressure, and the upper end and the lower end of the reversing valve are controlled to alternately attract, so that repeated vibration impact of the breaking drill rod 10-1 on a rock body is realized.
The bottom plate 12 of the rock breaking tank is provided with three groups of hydraulic breaking hammer devices 10 and two high-pressure water jet devices 9, each group of two hydraulic breaking hammer devices 10 is provided with one high-pressure water jet device 9, and a high-pressure water jet device 9 is arranged between two adjacent groups of hydraulic breaking hammer devices 10. As shown in figure 2, the water jet nozzle pipe 9-4 and the breaking drill rod 10-1 are not in the same plane, the water jet nozzle pipe 9-4 jets high-pressure water jet in advance to break the rock mass, after a crack is cut, the breaking drill rod 10-1 vertically impacts the rock mass to further break the rock mass, and the method has higher rock breaking efficiency and small abrasion to the breaking drill rod.
