Abstract

A machine for clearing loose debris from the walls and roofs of mine galleries is of flow construction, for low galleries and mounted on wheels which can be lowered and raised to suit the height of the gallery. The machine has a scraper tool consisting of three swinging arms, all operated by hydraulic actuator cylinders. The first arm (4) can be swung through a large arc to horizontally move a third arm (6) which forms the actual scraper tool. Arm movements can be controlled by hydraulic rams to give a nearly horizontal alignment for low roofs or a nearly vertical alignment of the first two arms for high roofs, while the third arm can be at a suitable angle for scraping.
