Abstract
Conveying apparatus for use in conveying mineral ore employs a curvilinear channel section or pan which joins straight groups of similar channel sections joined end-to-end together. A scraper-chain assembly circulates along the channel sections in upper and lower runs. A unit with a hollow housing is combined with the curvilinear channel section and this unit has an upstanding hollow pillar forming a hub on which two rollers are mounted for independent rotation. The rollers are shaped to engage with the scrapers of the scraper-chain assembly to guide the latter during its passage along the curvilinear channel section. To enable the roof of the mine working to be adequately supported over the zone in which the curvilinear section and unit are installed, a roof support with alternately shiftable hydraulic props is located within the hollow hub of the unit. The props are connected to a multi-part roof bar and extend through an elongate aperture in the housing top wall. The props can be shifted in successive steps independently of the housing and the conveyor channel sections.
