Technical Field

The invention relates to the field of mining, in particular to deep-sea mining equipment.

Background

The crushing heads of the existing mining vehicles and mineral collecting vehicles mostly adopt mechanical rollers, a plurality of groups of spines are arranged on the mechanical rollers, and the crushing heads crush and strip an ore layer from a rock stratum to realize mining crushing, but the method has some defects that when the thickness of the ore layer is not uniform, the spines crush the ore layer and the rock stratum with fixed thickness according to the length designed by the spines, so that the collected ore raw materials contain more rocks, the effective conveying rate is reduced, and on the other hand, the mechanical crushing heads can be damaged if the rock stratum is too hard; furthermore, the ore collected in this way is generally crushed unevenly and needs to be crushed again in the mine collection car before pipeline transportation can be performed. When the ore collection vehicle needs to collect rocks under the sea condition that an ore bed is distributed unevenly, the collection efficiency is low, the collection effect is not good, and real-time adjustment can not be performed according to geophysical prospecting data collected in an earlier stage. Particularly, the thickness of the deep sea cobalt-rich crust mined is 5-6 cm, the average thickness is about 2 cm, the thickness can reach 10-15 cm, the thickness of the thin ore bed is usually not uniform, the mining effect is poor by adopting the traditional mining method of the mechanical sharp spines, and even the mining method is difficult to develop. The mechanical crushing heads of existing mining trucks are relatively heavy and require additional re-crushing devices and more complex acquisition devices.

The electric water hammer technology is also called as the liquid-electric effect, and in recent years, the electric water hammer technology is gradually and experimentally applied to the field of sea exploration and ore crushing, and the principle is that a pulse generator converts electric energy into stress shock waves which are transmitted to submarine ores through a liquid medium to cause the splitting or crushing of ore deposit rocks. The mining working method and equipment design of the existing equipment for deep sea mining by using an electric water hammer are mostly in a theoretical stage, and a whole set of matched design scheme is not provided.
