PROBLEM TO BE SOLVED: To solve the problem that a screed device of a conventional paving machine have difficulty in changing the height or angle of a strike-off part with respect to the ground surface during the execution of construction work, and to provide a new screed device of a paving machine, which can easily change and adjust the amount of a pavement material fed to a screed plate even during the execution of construction work by the paving machine. SOLUTION: The new screed device 19 has the screed plate 24 attached to the lower edge of a screed frame 29, and a tamper 25 arranged on the front side of the screed plate 24. The tamper 25 carries out vertical movement along the front end surface of the screed plate 24. Further the screed device has the strike-off part 26 on the upstream side of the screed plate 24 with respect to a direction in which an asphalt mixture is fed to the screed plate 24, and more specifically on the front side of the tamper 25. The strike-off 26 part is formed like a cylinder and driven for forward rotation in the direction in which the mixture is fed to the screed plate 24 (in an arrow direction in the figure) by a hydraulic motor 27. Further the screed device has a deflector 28 arranged on the front side of the strike-off 26 part. COPYRIGHT: (C)2007,JPO&INPIT
