Telescopic arm type dumping plough used for mine

Abstract

The invention discloses a telescopic arm type dumping plough used for a mine. The telescopic arm type dumping plough used for the mine comprises a support truss arm, a front crawler-type chassis, a back crawler-type chassis, a telescopic material dumping arm and a telescopic belt conveyer. The front crawler-type chassis and the back crawler-type chassis are arranged in the middle and at the back end of the support truss arm respectively, and the front crawler-type chassis drives the support truss arm to swing around a rotating shaft of the back crawler-type chassis. The telescopic material dumping arm is arranged inside the support truss arm and is driven by the front crawler-type chassis, and conducts telescopic movement relative to the support truss arm. The telescopic belt conveyer is provided with a fixed part and a telescopic part, wherein the fixed part is fixedly arranged inside the support truss arm, and the telescopic part is arranged on the telescopic material dumping arm. Swinging and the telescopic movement of the telescopic belt conveyer are driven by swinging and the telescopic movement of the support truss arm and the telescopic material dumping arm, and discharging on an arbitrary point inside a fan-shaped area between a first radius and a second radius is achieved. According to the telescopic arm type dumping plough used for the mine, the operation safety can be ensured.

Description

technical field [0001] The invention relates to a soil dumper, in particular to a soil dumper for comprehensive treatment of tailings consolidation discharge in subsidence areas of underground metal mines. Background technique [0002] At present, the comprehensive management of underground mining subsidence areas is generally considered to be a worldwide problem. The tailings of metal mines are mostly discharged in the form of mud to form tailings ponds. The tailings ponds occupy a large area and pose a serious safety hazard. Mineral dressing reagents cause serious environmental pollution. [0003] At present, the more reasonable tailings treatment method is to use the consolidated tailings as the filling material in the subsidence area, and comprehensively control the subsidence area. One is to prolong the service life of the tailings pond; problem. [0004] At present, the comprehensive treatment method of the subsidence area of ​​the tailings consolidation discharge (o...

AI Technical Summary

Problems solved by technology

[0004] At present, the comprehensive treatment method of the subsidence area of ​​the tailings consolidation discharge (or called "disposal") has been used by some mines. The method is to blend the tailings with a certain proportion of cement and transport them to the edge of the subsidence pit by a belt conveyor. , and then use an excavator or a front-loading machine to transfer the tailings into the subsidence pit. Since the outer slope of the consolidated tailings is about 59°, and the angle of repose of the consolidated tailings is about 40°, the excavator or the front-loading machine is in the consolidation body. Edge work is at risk of slipping into collapsed areas and is inefficient
