Title:
ATTACHMENT ELIMINATOR FOR ROLLER FOR ROLLING COMPACTION
Document Type and Number:
Japanese Patent JP3033885
Kind Code:
B2
Abstract:
PURPOSE: To positively eliminate attachment from the periphery of a roller for rolling compaction over a long period of time.
CONSTITUTION: A fitting hole 11c provided in the plate 11 of an oscillating support body 7 oscillatingly supported to a frame 3, a fitting hole 12c provided on the cross direction centerline of a scraper 12, and the fitting hole 13c of a contact plate 13 are made coincide with one another. A bolt 14 is inserted through these fitting holes 11c, 12c, 13c so as to hold and fasten the scraper 12 at its cross direction center part between the plate 11 and the contact plate 13. Even in the case of using the wide scraper 12, the protruding quantity from the bolt 14 to the peripheral surface 5a of a roller for rolling compaction can be made small so as to use the scraper 12 in the state of high stiffness. When one end side of the scraper 12 wears, the scraper 12 is vertically inverted to use the other end side.
