Open-pit mining machine

Abstract

The invention relates to an open-pit mining machine. The open-pit mining machine comprises a machine body, rocker arm groups, a collection mechanism and a dust suppression mechanism, wherein each rocker arm group is arranged on each of left side and right side of the machine body and comprises an upper rocker arm and a lower rocker arm; large planes of drums of the upper rocker arms are flush; large planes of drums of the lower rocker arms are flush; the large planes of the drums of the upper rocker arms are deviated by a distance toward the ore wall than the large planes of the drums of the lower rocker arms; the collection mechanism collects ore sliced and broken by the drums of the upper rocker arms and transfers the ore to a conveyor below the mining machine; ore sliced and broken by the drums of the lower rocker arms directly falls on the conveyor through a dust collection cover of the dust suppression mechanism; the collection mechanism and the dust suppression mechanism controland suppress local mineral powder at the rocker arms while assisting in transferring the ore. The open-pit mining machine can realize continuous slicing, breaking and collection, realizes clean mining, is simple in structure, high in efficiency and suitable for full-seam mining of medium-thick seams, and requires little investment.

Description

technical field [0001] The invention relates to an open-pit mining machine, which is mainly used to meet the needs of medium-thick ore seam mining in small and medium-sized mines. Background technique [0002] The conditions of different working faces of open-pit mines vary greatly, such as the thickness of some meters and some tens of meters, and the corresponding equipment is different. For the mining of thick ore seams, a large number of single-bucket excavators (such as hydraulic shovels and electric shovels) are currently used for mining, and at the same time, they are equipped with car transportation, crushers, and belt conveyors. Due to the large number of auxiliary supporting equipment in the working face, the maintenance workload is huge. , The problem of mining cost per ton of material and mining efficiency of single bucket excavator, a discontinuous mining system, is becoming more and more serious. With the development of technology and the emergence of extra-thi...

AI Technical Summary

Problems solved by technology

With the development of technology and the emergence of extra-thick ore seams, giant bucket-wheel excavators, supporting mobile crushers and mobile loaders have been gradually developed. Although this continuous mining can adapt to the efficient mining of extra-thick ore seams, its procurement cost Huge, it is uneconomical for the mining of ore seams below medium thickness, and cannot meet the needs of some small and medium mines
