WORKING MEMBER OF TUBULAR CONVEYOR Russian patent published in 2001 - IPC

Abstract RU 2172288 C1

FIELD: mechanical engineering; conveyors for transportation of loose materials. SUBSTANCE: working member of tubular conveyor has closed traction circuit on vertical links of which transporting scrapers are secured. Some scrapers are installed for cleaning conveyor tube walls. At least one pair of cleaning scrapers is secured eccentrically relative to axis of traction chain vertical links. Eccentricities of each pair of cleaning scrapers are relatively opposite. EFFECT: improved cleaning of tube with prevention of wedging of working member, reduced cost of working member. 7 dwg
