Abstract
A paving machine employs an electrically heated screed assembly to uniformly heat a screed plate of the machine. Uniform heating is achieved by inserting a thermally conductive plate between electrical heating elements and the screed plate. An insulation layer may be provided above the heating elements to direct the heat downward into the thermally conductive plate. The heat spreads relatively uniformly throughout the thermally conductive plate, thereby uniformly heating the screed plate. A clamping mechanism is also provided that, when tightened, provides a compressive force, thereby holding the assembly in place. When released, the pressure is alleviated, thus permitting a heating element to be removed for repair or replacement without the need to remove the screed plate.
Claims (2)
1. An electrically heated screed assembly for use with a paving machine, comprising:
a screed plate;
a thermally conductive plate disposed above and in direct contact with the screed plate; and an electrical heating element disposed above and in direct contact with said thermally conductive plate;
wherein heating the heating element heats the thermally conductive plate, thus uniformly heating the screed plate.
a screed plate;
a thermally conductive plate disposed above and in direct contact with the screed plate; and an electrical heating element disposed above and in direct contact with said thermally conductive plate;
wherein heating the heating element heats the thermally conductive plate, thus uniformly heating the screed plate.
2. The assembly of claim 1, wherein the heating element is made of a metallic material.
