摘要： An asphalt cutter that includes a hollow cylindrical body with a plurality of longitudinally aligned, curved teeth evenly spaced apart along the body's lower perimeter edge. The teeth are curved in a forward direction of the normal rotation of the body during use with a hardened carbide edge formed thereon. The teeth are slightly wider in cross-section than the side wall of the cylindrical body. During use, a circular gap is formed in the asphalt which enables a center plug formed therein to be easily removed by utility workers. Attached to the top end of the cylindrical body is a longitudinally aligned hollow neck with a top opening. During assembly, the drive shaft on a hydraulic motor attached to the articulating boom is inserted into the neck. A bolt connects the neck and drive shaft together. In the preferred embodiment, an optional elongated guide flag is longitudinally aligned with the cutter. During operation, the operator watches an arrow indicator printed on the side of the guide flag to maintain the drive shaft and cylindrical body in a vertically aligned position over the asphalt during the cutting process.
摘要翻译：一种沥青切割机，其包括具有沿主体的下周边边缘均匀间隔开的多个纵向排列的弯曲齿的中空圆柱体。在使用期间，齿在身体的正常旋转的向前方向上弯曲，其上形成有硬化的碳化物边缘。齿的横截面比圆柱体的侧壁略宽。在使用中，在沥青中形成圆形间隙，使得其中形成的中心塞能够被公用事业工作者容易地移除。连接到圆柱体的顶端是具有顶部开口的纵向排列的中空颈部。在组装期间，附接到铰接吊杆的液压马达上的驱动轴插入颈部。螺栓将颈部和驱动轴连接在一起。在优选实施例中，可选的细长导向标志与切割器纵向对准。在操作期间，操作者观察印刷在导向标记侧面的箭头指示器，以在切割过程中将驱动轴和圆柱体保持在沥青上方的垂直对准位置。
