ORGANIC FERTILIZER SPREADER

摘要

FIELD: agricultural engineering, in particular, machines for spreading of organic fertilizers from piles over field surface. ^ SUBSTANCE: organic fertilizer spreader has frame mounted on supporting wheels, hanger mechanism and multiple-blade rotors driven from tractor power shaft. Hanger mechanism and rotors are mounted on frame. Rotors are made in the form of four rows of spreading blades. Spreader has flow divider with lifting knife. Flow divider is positioned under third and fourth rows of blades for longitudinal displacement in direction opposite to that of spreader and is provided with position adjustment mechanism. Frame is positioned for movement in vertical plane. Position adjustment mechanism for flow divider may be made in the form of damping springs or hydraulic system or pneumatic system. ^ EFFECT: increased efficiency in operation of each row of blades and reduced draft of spreader. ^ 4 cl, 4 dwg
