The present invention relates to a manufacturing apparatus for rolled paving stone which cuts stone in a cuboid shape in a prescribed length unit to manufacture block stone, and inserts the manufactured block stone into a rolling drum to wear away corners of the block stone by friction between the block stone and the rolling drum in the rolling drum to manufacture rolled paving stone, and rolled paving stone manufactured thereby. To achieve the objective, the manufacturing apparatus for rolled paving stone according to the present invention comprises: a cutting unit to cut supplied stone formed in a cuboid shape in a unit length to manufacture block stone; a feeding conveyor to transport the block stone discharged from the cutting unit; a rolling drum unit wherein a feeding hole through which the block stone transported by the feeding conveyor is fed is formed thereon, the fed block stone is manufactured into rolled paving stone by rolling, and a discharge hole through which the manufactured rolled paving stone is discharged is formed thereon; a washing water supply unit to supply washing water to the rolling drum unit; and a discharge conveyor to transport the rolled paving stone discharged from the rolling drum unit. The rolling drum unit comprises: a frame separated from the ground by a prescribed gap; a rolling drum installed on an upper portion of the frame, inclined downwards from the feeding hole to the discharge hole, and rotated by a drum motor; a plurality of circular bars installed on an inner surface of the rolling drum at regular intervals along a longitudinal direction; a hydraulic lifting cylinder installed on a feeding hole side of the frame to change a height of the feeding hole; and a rotation shaft installed on a lower portion of a discharge hole side of the frame, and hinge-mounted on a base unit and the frame. |
