Machine for winning minerals or for driving underground roadways

摘要

Machine for winning minerals or for parting rock. A hitherto known machine for parting minerals works with hydraulic activators for producing linear vibrations and has not proved successful in practice. According to the invention, a machine is proposed which uses a double vibration drive as activator, which consists of two shafts each mounted at several points and provided with unbalance masses, drive motors being allocated to each unbalance point.
