A self-loading conveyor for the removal of excavated material from a cavity produced by a boring or winning machine, comprising an inclined channel and material removing scrapers driven by an endless chain and adapted to travel in the channel. A collecting foot for the excavated material is disposed at the lower end of the channel and is provided with a protective cover. A driving head is disposed at the upper end of the channel to drive the endless chain. The collecting foot has lateral apertures and is reciprocable in a direction parallel to the wall of the cavity from which the excavated material is to be removed, thereby effecting the collecting of the excavated material through the lateral apertures on each side of the foot.
