SCREED PLATE ARRANGEMENT AND METHOD OF ATTACHING A SCREED PLATE

摘要

Asphalt paving machine 10 includes screed assembly 12, plurality of lower and upper plate connectors 50, 52, and upper and lower screed plates 36, 38, each having openings 70, 72, and an electric heater 82 at least partially disposed between the plates 36, 38. Upper and lower plate connectors 54, 56 extend into openings 70, 72 of the respective upper and lower screed plates 36, 38 and bores 60, 62, 64, 66 of a frame portion 32 of the screed assembly 12 to couple the plates to the frame portion 32. The upper plate connectors 50, 52 couple the upper screed plate 36 to the frame portion 32 independently of the lower screed plate 38, so the lower plate 38 is displaceable from the upper plate 36 and the frame portion 32.
