FIELD: mechanical engineering; material transportation facilities. ^ SUBSTANCE: proposed plant for transportation of loose materials contains transportation belt installed for movement from loading position to unloading position which passes over deflecting drum at loading and unloading positions. Device by means of which transportation belt can be turned through approximately 180° after deflecting drum arranged in zone of unloading and device by means of which transportation belt can be turned backwards through approximately 180° arranged before deflecting drum in zone of loading are provided. Transportation belt is furnished with great number of carrier rollers at both sides, being installed at distance from each other with possibility of movement along guides. Each turning device is formed by carrying structure, like hollow cylinder, on inner side of which two spiral guides are arranged along which carrier rollers on side of transportation belt move. Both guides are approximately diametrically opposite to each other, being made for turning through approximately 180°over length of carrying structure. ^ EFFECT: improved reliability of plant in operation. ^ 8 cl, 2 dwg |
