Mining head suitable for exploiting deep-sea cobalt-rich crust

Abstract

The invention relates to a mining head suitable for exploiting a deep-sea cobalt-rich crust. The mining head comprises a pick component and is characterized in that the pick component is arranged on the wall of a milling and digging roller, a spindle penetrates the milling and digging roller and is fixed to a milling and digging rack, a milling and digging motor is fixed to the milling and diggingrack, the milling and digging rack is further provided with a compensator, a first leather bag and first springs are arranged in the compensator, the first leather bag is filled with oil, the first springs are arranged on two sides of the first leather bag, and the bottom of the compensator is provided with a compensation oil port; two ends of the spindle are provided with bearings, a left bearing cavity exhaust port is arranged in a left bearing cavity, a right bearing cavity exhaust port and a right bearing cavity oil supplementing port are arranged in the right bearing cavity, the spindleis provided with an oil hole, the left bearing cavity and the right bearing cavity are communicated through the oil hole, and the compensation oil port is communicated with the right bearing cavity oil supplementing port. The mining head has the advantages that the mining head can adapt to deep-sea areas within 6000m; by a self-adaptation frequency-variable excitation function, crushing cutting force fluctuation range is lowered, pick service life is prolonged, and milling, digging and crushing efficiency is increased.

Description

technical field [0001] The invention relates to a mining head, in particular to a mining head suitable for mining cobalt-rich crusts in deep sea. Background technique [0002] At present, the known mining heads are basically used for land excavation. They have simple structures and do not require strict sealing and pressure resistance; most of them have no auxiliary crushing function, the efficiency of crushing and stripping is low, the energy consumption of the operation is high, and the requirements for the power source of the main equipment are high. For ocean and water environment operations, there is no quite mature mining device at present. [0003] However, with the development of the economy, marine resources have become a key direction of national development, among which deep-sea cobalt-rich crust mineral resources are one of the key resources, which involves the exploitation of seabed cobalt-rich crust mineral resources, but domestic and even international Mining...

Problems solved by technology

[0006] CN 105735999 A discloses an underwater space mining device, which includes a frame, a conveyor, a mining head installed on the frame, and a conveying pipe connecting the conveyor and the mining head, and the underwater space mining device is installed on the frame. The buoyancy components that remain suspended underwater and the propulsion mechanism used to drive the underwater space mining device to move underwater mainly solve the problems of subsidence, slipping and inability to walk in the underwater space mining device. How does the mining head work in deep water? maintain pressure balance under pressure, which is not introduced in the text
