FIELD: open-cast mining.;SUBSTANCE: invention relates to continuous-operation self-propelled device designed for checking possibility of mining mineral materials and taking out interlayers whose properties, from point of view of their breaking and further transportation, are of vital importance at open cast mining. Proposed device has running gear, frame with drive unit and control panel and cutting drum arranged before running gear and equipped with cutting tools. Said drum is installed in supports of carrying frame for rotation around horizontal axis and is made for adjusting position in height by means of cylinder installed between frames and carrying frame. Crawler-type running gear is used. Cutting drum passes over entire width of device, and it is furnished with guide partitions and guard shield, is functionally connected with chute-like housing and is made for stepless change of speed of rotation, speed of feed and adjusting transverse tilting from one of two sides relative to working platform owing to vertical adjustment of position of one of hinge joints connection device frame and carrying frame which is made in form of forked rotary cantilever.;EFFECT: improved operating capabilities of device.;5 cl, 5 dwg
