| Zusammenfassung: | A cutting drum for a mining machine, for example a shearer drum comprising helical vanes, to which picks are secured at spaced intervals peripherally thereof. In conventional practice, housings for the picks are secured such as by welding directly to the shearer drum vane. In accordance with the invention, a mounting device is fixedly secured to the shearer drum vane, and the housing for the pick is releasably secured to the mounting device. This enables the pick housings to be readily removed from the shearer drum, in the event that one or more of the pick housings becomes damaged during operation of the machine. |
