FIELD: mechanical engineering; conveyor transport.
SUBSTANCE: invention relates to screw conveyors which can be used as independent transportation means and as feeders. Proposed screw conveyor has carrying housing with semiround bottom, working member in form of flexible spiral flights are made with deformation decreasing in direction to drive flight under action of loads, and/or flexible spiral is provided at least with one rod connected with inner sides of its flights. Conveyor has support base located on semiround bottom.
EFFECT: improved reliability and increased service life of conveyor.
