From Wikipedia, the free encyclopedia.
An auger is a device for moving material or liquid by means of a rotating helical flighting. The material is moved along the axis of rotation. A drill bit uses this mechanism to remove shavings from a hole being drilled. For some uses the helical flighting is enclosed in a tube, for other uses the flighting is not encased.
An Archimedes screw is essentially an auger that lifts water from a lake or river.
Snowblowers use an auger to move snow towards an impeller where it is thrown into the discharge chute. Combines use both enclosed and non enclosed augers to move the unthreshed crop into the threshing mechanism and to move the grain into and out of the machine's hopper. A Zamboni uses an auger to remove loose ice particles of the ice surface.
A type of flexible auger is used by plumbers to remove obstructions from pipes. This is called a snake.
(ed: An auger is essentially a big screw.)
