FIELD: agricultural engineering. SUBSTANCE: elevator has driving and driven sprockets, flexible tie-rod members with asymmetrically curved rods fixed on said members. Elevator has three flexible members. Curved rods are arranged on middle member in offset relation, with offset value being equal to rod pitch. Outer flexible tie-rod members are provided with leading rollers forming rod-type elevator cascades. EFFECT: increased efficiency by intensified action of elevator rods upon root heap and simplified construction. 2 cl, 2 dwg |
