Compact connecting and transferring system for crossheading

Abstract

The invention discloses a compact connecting and transferring system for a crossheading. The compact connecting and transferring system comprises a transferring reversed loader, a stage loader, a screening reversed loader, a screening crusher, a first connecting piece, a second connecting piece, a screening belt conveyor and a supporting piece, wherein the transferring reversed loader comprises alanding section and a bridge section; and the landing section is horizontally arranged. According to the compact connecting and transferring system for the crossheading, the transferring reversed loader is additionally arranged, and the height of the transferring reversed loader is greatly reduced compared with the height of the belt conveyor, so that the design height of a crossheading roadway ofa working face is reduced, and the drivage cost of the roadway is reduced; the stage loader, the screening reversed loader and the screening crusher are movably installed on the transferring reversedloader, and the screening reversed loader and the screening crusher are connected with the screening belt conveyor through the transferring reversed loader; and a self-moving tail of the screening belt conveyor is the same as a self-moving tail of a common belt conveyor, the screening reversed loader and the screening crusher can be dismantled near a terminal line of the working face, and then the stage loader is connected with the self-moving tail of the screening belt conveyor, so that the length of the whole system is reduced, and the problem that the terminal line extends forwards due tothe equipment length is avoided.

Description

technical field [0001] The invention relates to the technical field of coal mining and conveying devices, in particular to a compact trough connection and reloading system. Background technique [0002] The general purpose of the connecting and reloading system for trough is to realize the screening function of coal before passing through the crusher, and to avoid the problem that the lump coal rate is greatly reduced after all the coal passes through the crusher. The traditional connecting and reloading system for trough Generally, it is composed of sieve trough reloading machine, screening reloading machine, screening crusher and belt self-moving machine tail for screening. The belt self-moving machine tail is relatively high and long, so the height of the whole system is relatively high. , which leads to the need to increase the height of the roadway in the design of the tunnel roadway in coal mines, which increases the cost of roadway excavation. At the same time, the pa...

[0002] The general purpose of the connecting and reloading system for trough is to realize the screening function of coal before passing through the crusher, and to avoid the problem that the lump coal rate is greatly reduced after all the coal passes through the crusher. The traditional connecting and reloading system for trough Generally, it is composed of sieve trough reloading machine, screening reloading machine, screening crusher and belt self-moving machine tail for screening. The belt self-moving machine tail is relatively high and long, so the height of the whole system is relatively high. , which leads to the need to increase the height of the roadway in the design of the tunnel roadway in coal mines, which increases the cost of roadway excavation. At the same time, the particularity of the belt self-moving machine tail leads to a longer length of the entire connection and reloading system, making the stop line of the working face forward Extended, reduced coalfield recovery
