FIELD: transportation or storage devices, particularly conveyers for mining or other industries. ^ SUBSTANCE: conveyer comprises closed continuous belt turning round drive, tension and reverse drums. Belt forms loop part. Outer and inner running rollers are connected to side edges of conveyer belt so that running rollers may surround tubular guides. Tension drum with load-applying means is arranged on vertical band loop part having ascending and descending flights in area of band leaving additional drive drum and in area of band coming onto rotary drum. Vertical flat guides are installed at ends of tubular guides along both belt sides. Vertical flat guides may cooperate with outer running rollers. Length of vertical flat guides is chosen in dependence of calculated tension drum speed. All flat guides have edges bent towards outer rollers. Flat guides arranged on ascending belt flight have edges bent from belt formed on opposite sides thereof. Tubular guides located at ascending flight have conical nozzles facing downwards. ^ EFFECT: increased tension drum speed of rotation, extended capabilities of conveyer usage. ^ 5 dwg |
