发明名称 APPARATUS FOR SCREEDING UNCURED CONCRETE SURFACES
摘要 A wheeled screeding device is movable over a surface of uncured concrete and is operable to level and smooth the uncured concrete surface. The wheeled screeding device includes a wheeled support having a frame portion supported by at least one wheel, with the wheel defining an axis of rotation. A screed head is mounted to the frame portion and is at least partially supportable on an uncured concrete surface. The screed head is pivotable about a pivot axis generally normal to the axis of rotation and relative to the wheel to adjust an angle of the screed head relative to the axis of rotation. The wheeled screeding device is movable in a direction of travel during screeding of the concrete surface and the pivot axis may be generally parallel to the direction of travel of the wheeled screeding device during screeding of the concrete surface.
