Embodiment Construction

[0027] FIG. 1 shows a greatly schematically simplified approach conveyor 1 designed as a face-entry transfer conveyor, as it can be used in underground mining, in particular in coal mining. The material recovered by the face conveyor on the mining face, not otherwise shown, is thrown onto the entry conveyor 1 on a special trough formed as a cross frame (Kreuzrahmen) 3, where not only the face conveyor 2 Furthermore, the alley conveyors 1 are designed as double-center scraper chain conveyors, including two chain strands 4 of a double-center scraper chain, which are only schematically described here for the alley conveyor 1 . The two shown chain strands 4 of the scraper chain run in the upper branch of the conveying chute 7 from the cross frame to the drive station 5, which consists of a number of identically formed standard chute segments, not shown in detail, As this is known to the skilled person. The two chain strands 4 are deflected at a drive station 5 arranged at one end...

Abstract

The invention relates to a tunnel conveyor, in particular a tunnel transfer conveyor. The said invention comprises a conveying shute conformed in aid of many chute knots (10) tensily and joint type actively connected with each other, driving station and / or turning station for scraper chain and mounted on the two end of the said conveying shute, each chute knot comprising an up branch defined by lateral section material and conveying bottom and a down branch for scraper chain (4) and a holding mechanism (18) mounted outside the lateral section material and used for chute knot connecting gear. In order to reduce the wear of the dray chain conveyer and only use minor driving power, a chute array (8) with many chute knots connected with each other before and after are mounted in conveying shute and each chute knot is joint type actively connected with each other by a central floating bearing (11) in the central longitudinal axis of conveying shute or each chute knot. The invention also relates to a chute knot with central floating bearing.

Description

technical field [0001] The invention relates to an alley conveyor, in particular an alley transfer conveyor or crushing conveyor, comprising a conveying chute formed by means of a plurality of tensile and articulated chute sections connected to each other, wherein The conveyor chute is provided at both ends with drive and / or deflection stations for the double scraper chain, each chute section having an upper branch delimited by means of side profiles and a conveying bottom and a lower branch for the scraper chain and Accommodating mechanism for chute link joints provided on the outside of the side profile. The invention also relates to a chute section for a corresponding road conveyor, comprising an upper branch delimited by means of side profiles and a conveying bottom, a lower branch formed below the upper branch and a Accommodating mechanism for chute joint connection mechanism. Background technique [0002] In underground mining, especially in underground coal mining, ...
