SELF-PROPELLED ROAD-BUILDING ROTOTILLING MACHINE Russian patent published in 2007 - IPC E01C23/88 

FIELD: road building.

SUBSTANCE: invention relates to self-propelled road-building rototilling machine including machine frame with rotor fitted inside for turning between side plate perpendicular to rotor axle. Said rotor has base and cylinder and it can set into rotation through drive arranged on outer side of side plate from external side and through reduction gear. Side plate made of replaceable alternatively installed cylinders of different width and arranged opposite to side plate from inlet side, can be easily removed to determine free side of machine to which one end face of rotor adjoins almost flatly. To permit milling of surface close of edge, reduction gear is installed on drive inlet side. Reduction gas includes outlet member installed in inner side of drive side plate from inlet side, and surface of shell forms seat surface of rotor cylinder members which can slide from free side. Rotor base should be preferably connected to reduction gear by free end face of outlet member not to interfere with cylinder members sliding along surface.

EFFECT: improved quality of operation.
