ABSTRACT:
A self-propelled conveyor includes a number of auger sections each section including at least one spiral mounted on a shaft, a housing surrounding the spiral and having two end terminations, and structure for driving of one spiral by driving an adjacent spiral whether or not the shaft of the spirals are in line with each other. The driving structure can comprise axially and radially extending projections from each adjacent shaft providing a lost motion connection between the shafts, or a universal joint. More than one auger may be mounted in each housing section, with a common drive shaft for the augers connected by a universal connection to a similar drive shaft for an adjacent auger section. The end terminations of the housing allow relative pivotal movement between adjacent housing sections at least in a horizontal plane, and comprise inter-engaging cylindrical section elements allowing relative rotational movement between adjacent housing sections of at least about 15.degree.. Structures are provided for moving in the auger sections, the structures continuously in contact with the mine floor, such as a mining chain having loose connections between the links, or wheels on axles. The conveyor is particularly useful in association with a cutting head of a miner for practicing a method of cutting and conveying mined material from a mine site through a non-linear bore. A drive motor for the auger sections is provided every few auger sections.
