摘要 |
A plough for winning material from a mineral face comprises two plough bodies connected together in a tension-proof manner. The two plough bodies are provided with detachable cutters at each end thereof. A rigid beam, also provided with detachable cutters, connects the two plough bodies at a predetermined height. The beam carries a plough upper part for each of the two plough bodies. Each plough upper part is provided with detachable cutters and is pivotably mounted on the beam by means of a parallelogram linkage. Each plough upper part is guided and supported on the beam by means of a keyed connection.
