Abstract

Apparatus for gathering particulate material in mines and similar plants has a mobile platform which collects particulate material and surrounds the trailing end of a material removing conveyor. The sides of the trailing end of the conveyor are flanked by plate-like carriers on each of which are fixed several beams serving to push gathered material toward and onto the conveyor in response to movement of the carriers toward the conveyor. The carriers are movable toward and away from the conveyor by motors which are installed beneath the platform, and the apparatus further employs stationary or reciprocable barriers, one behind each beam, which prevent the beams from pushing material away from the conveyor during return strokes of the carriers. Those ends of the beams and barriers which face in the direction of forward movement of the platform slope forwardly and downwardly to facilitate penetration beneath the accumulations of particulate material on the platform.
