FIELD: mining. ^ SUBSTANCE: invention refers to mining engineering, and namely to the excavating device, particularly to grabbing excavator for erecting soil walls. Excavating device consists of a supporting frame made with the possibility of being connected to basic machine, a working member whereon excavation working tools are located and which is installed with the possibility of being turned on the supporting frame by means of the supporting device, and rotary device for turning the working member relative to the supporting frame around rotation axis. Rotary device consists of at least one linear drive and cord or chain transfer mechanism by means of which linear movement created by linear drive can be converted to rotary movement. ^ EFFECT: simplifying and strengthening the working member design with the possibility of its turning with high reliability. ^ 10 cl, 6 dwg |
