Asphalt paving machine with liftable, adjustable auger mechanisms

摘要

An improved mounting arrangement for the auger and auger drive mechanism of a floating screed type asphalt paver. A drive box, pivotally mounted at the back of the paver, supports and drives the inboard ends of left side and right side augers. A cantilever beam, mounted on the drive box, extends laterally over both augers and provides outboard bearing support. Actuator means is provided for controllably pivoting the entire assembly about an axis located in front of the augers, enabling the augers to be lifted and lowered for loading/unloading operations, clearing obstructions, etc., and also enabling the auger to be adjusted vertically during paving.
