Proposed conveyor has endless belt closed on drive and tension drums and brackets secured to belt sides. Rolls of chute section are installed by means of axle for engagement with tubular guides. Each bracket consists of two links. Link secured on belt is made in form of hook with horn pointed downwards relative to belt plane. Link with rolls is made in form of loop whose plane is arranged at right angle relative to hook plane for coupling with hook. Axles of rolls in loop are installed by means of two pairs of cross strips welded to loop from top and bottom and provided with holes for fitting the axles which have shoulders at roll sides and pressure nuts at opposite sides. EFFECT: improved reliability and increased service life of conveyor, reduced metal usage. 2 dwg
