FIELD: mechanical engineering; belt conveyors. ^ SUBSTANCE: invention relates to belt conveyors with single-drum drive and sliding supports on conveyor belt return run. Proposed belt conveyor has frame, flexible endless belt closed on drive and tension drums forming carrying run on roller supports and return run on sliding supports, return run deflecting device installed for engagement with working surface of belt arranged in zone of running off of return run from drive drum and receiving funnel for material unloading from conveyor. Deflecting device is made in form of guide curvilinear in vertical plane with convex pointed to side of belt working surface and in plan in form of V-shaped plows following each other, installed with clearances, pointed by peaks to side opposite to direction of movement of return run and arranged symmetrically relative to its longitudinal axis. Plows are interconnected by central longitudinal rib coinciding with longitudinal axis of belt, side and cross beams, and both vertical walls of plows are provided with slot cutouts from side of belt return run which are reduced in steps at change from one plow to the other in direction of belt movement, and angle between walls of plows is less than double angle of friction between particles of transported load and walls of plows. Curvilinear guide is installed by one end of axle and by other and is spring-loaded from side of drive drum relative to frame through cross beam. Belt unloader is installed under guide with possibility of delivery of belt cleaning products to receiving funnel of conveyor. ^ EFFECT: combination of functions of deflecting drum and belt cleaning appliance in one device with increase of efficiency of cleaning of belt return run and reliability of functioning of sliding supports on belt return run. ^ 2 cl, 5 dwg |
