ORGANIC FERTILIZER SPREADER Russian patent published in 2005 - IPC

FIELD: agricultural engineering, in particular, machines for spreading of organic fertilizer from windrows.

SUBSTANCE: organic fertilizer spreader has frame, hitching mechanism, drive mechanism, flow divider, swing knife and multiple-blade rotors. Each of blade rotors has four rows of spreading blades, wherein each sequential row of blades is offset to side opposite to direction of rotation. Length of blades is increasing from rotor leading end in direction of advancement of unit. Spreader is additionally provided with five rows of radial feeding blades arranged in alternation between rows of spreading blades at an angle α=10-30 deg with respect to plane of rotation of rotors. Length of rotor is equal to length of spreading blades arranged alternatively in one row and is increasing from leading end in direction of advancement of spreader. Feeding blades, beginning from second row, are uniformly offset relative to spreading blades of previous row. Feeding blades of first row are uniformly offset relative to forth row of spreading blades. Feeding blades of terminating row of blades have length corresponding to radius of flow divider.

EFFECT: increased efficiency by uniform spreading of organic fertilizers over soil surface, and improved granulometric composition of organic fertilizer.
