dc.description.abstract A new design of the bottom unload non-bucket rotor (BUNBR) for an open-pit excavator with additional end chisels is described. It makes it possible not only to increase the output due to additional end chisels on the shell, but also to reduce the slope stress due to soil cutting from top to bottom on the working face and creation of a wider berm in comparison with the existing constructions of rotary working bodies. The method of calculation of soil cutting with the end chisel in the form of a two-sided skewed wedge is presented. Based on the spatial scheme of the cutting force components acting in the soil cutting, the expressions in coordinate axes for soil resistance to cutting with the end chisel were determined. These results were used to derive expressions for the tangential and end (lateral) cutting force exerted by a two-sided skewed wedge mounted at the BUNBR end side and to determine the total soil cutting force simultaneously exerted by the corner and end chisels. ru
