| 摘要 |
The present invention relates to a screed for a paving machine that includes a flexible smoothing plate, a vertex block, a first actuator, and a second actuator. The flexible smoothing plate is provided with a longitudinal length and an outer longitudinal end. The vertex block is located on top of the flexible smoothing plate. The first actuator is connected to the outer longitudinal end and adapted to selectively adjust an elevation of the outer longitudinal end so that the outer longitudinal end of the flexible smoothing plate forms a berm by flexing about the vertex block and extending upward at an angle relative to an inner portion of the flexible smoothing plate. The second actuator is connected to the vertex block and configured to adjust the length of the berm by selectively repositioning the vertex block along the longitudinal length of the flexible smoothing plate. |
