FIELD: transport.SUBSTANCE: conveyor comprises planar conveyor belt 1 with two or one draw chains 2 running around drive and tension sprockets 3, 4 and idle rolls 5 running in guides 6 secured at conveyor frame struts 7. Intermediate drive is composed of twin or single drive sprocket 8 articulated with sprockets 9 in diameter equal to that of the drive sprocket and arranged along conveyor lengthwise axis and sprockets articulated therewith with two or one draw chain of planar belt. Diameter of intermediate drive sprockets equals that of the head drive sprocket. Articulation between intermediate shaft sprockets is composed of equal-diameter gear wheels 12, 13 fitted on every shaft 10, 11 and idle gears 14 coupled therewith. Head and intermediate drive motor rotors run in synchronism.EFFECT: higher reliability of conveyor and intermediate drive force.2 cl, 3 dwg |
