Ground cable laying plough - has hydraulic cylinders for adjusting angle and inclination of plough blade

摘要

The plough is attached to the outrigger arm (10) of an excavator, with a hydraulic cylinder (5) between the plough blade (1) and the outrigger arm (10) for exerting a side force on the plough blade (1), allowing it to rotate about a vertical axis (4). A horizontal pivot linkage may be used to allow the plough blade (1) to pivot from the vertical plane, under control of a second hydraulic cylinder (2), the setting force provided by each hydraulic cylinder (5, 2) transferred to a rack and pinion setting drive. ADVANTAGE - Allows precise straight plough line.
