<p>CONTINUOUS LOADING APPARATUS AND METHOD Loading apparatus particularly for mucking operations in confined space The apparatus includes primary and secondary conveyors disposed in tandem about a longitudinal axis so that a rear portion of the primary conveyor is above the forward portion of the secondary conveyor. The primary conveyor can extend axially forwardly from the secondary conveyor assembly and has a penetrator mounted adjacent the forward portion thereof, the penetrator being adapted to be oscillated, automatically if desired in several modes dependent on loading conditions, to facilitate loading of material onto the primary conveyor as the primary conveyor is extended. The apparatus has a supporting body which carries the secondary conveyor and forms a rigid supporting structure which is carried on adjustable legs to restrain the apparatus against mucking loads and to enable the apparatus to be set in a desired attitude so that the penetrator follows a pre-selected path or plane, irrespective of inclination or roughness of ground supporting the apparatus or resilience of apparatus suspension. The apparatus further can be restrained against movement by extendable rams which extend upwardly and/or laterally from the apparatus to engage adjacent rock surfaces, if available, so as to augment restraint o-f legs. When operating, as loading conditions become more difficult, frequency of oscillation of the penetrator can be decreased whilst amplitude increases. In more difficult conditions, the penetrator is raised progressively to reduce load on the penetrator, and the penetrator can he subjected to two oscillations having different frequencies and amplitudes.</p> |
