APPARATUS AND METHOD FOR CONTROLLING THE MATERIAL FEED SYSTEM OF A PAVER

摘要

An apparatus for controlling a material feed system of a paver (100) is disclosed. The material feed system includes a feeder conveyor (115) and a spreader auger (125). The apparatus includes a sensor that monitors the amount of material at the edge of the screed (135) and responsively produces an actual material height signal. A rotary switch (720) produces a desired material height signal indicative of a desired amount of material at the edge of the screed. A controller (410) receives the actual and desired material height signals, determines a desired rotational speed of the auger in response to the difference between the signal magnitudes, and produces a command signal to rotate the auger at the desired speed. An electrohydraulic system (300) receives the command signal and rotates the auger at the desired rotational speed.
