Mine telescopic boom dumper

Abstract

The invention discloses a mining telescopic arm type soil dumper, which comprises a support truss arm, a front crawler chassis, a rear crawler chassis, a telescopic discharge arm and a telescopic belt conveyor; the front and rear crawler chassis are respectively arranged on the support The middle part and the rear end of the truss arm, the supporting truss arm swings around the rotary shaft of the rear crawler chassis driven by the front crawler chassis; Perform telescopic movement; the telescopic belt conveyor has a fixed part and a telescopic part, the fixed part is fixed in the support truss arm, and the telescopic part is set on the telescopic discharge arm; through the swing and telescopic movement of the support truss arm and the telescopic discharge arm The movement drives the swing and telescopic movement of the telescopic belt conveyor to realize unloading at any point in the fan-shaped area between the first radius and the second radius. The soil dumper of the invention can ensure the safety of operation.

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
