FIELD: conveyor building. ^ SUBSTANCE: invention relates to tubular belt conveyors and is intended for transportation of bulk cargoes by the routes curved in the horizontal and vertical planes. The conveyor contains a continuous flexible belt fitted on the driving and tensioning drums, supports, secured on a frame with a possibility of interaction with the external surface of the belt over the whole perimeter of the same and formation of a round trough for accommodation of the transported load inside it. The support is made in the shape of a spiral of round cross-section, made of elastic material with antifriction external layer. ^ EFFECT: simplification and cost saving of the design of supports for the belt, reduction of materials consumption of the conveyor, increase of reliability of operation of the same. ^ 4 cl, 3 dwg |
