ORGANIC FERTILIZER PILER Russian patent published in 2005 - IPC

FIELD: agriculture, in particular, equipment for piling of organic fertilizer.

SUBSTANCE: organic fertilizer piler has body equipped with bottom made in the form of conveyor, and shaft provided with drive and arranged at conveyor exit end. Chains with cutting edges at peripheral parts of chains are fixed lengthwise of shaft. Protective housing is disposed above shaft and guiding shield and immovable cutting edges are disposed under shaft rearward of conveyor. Surface of guiding shield under chains joined in pairs is made in the form of concave curved portions, with curvature of curved portions corresponding to dependence: , where a is distance from center of coordinates of axes XOY to lower point of chain line making up working surface guide of concave curved portions of guiding shield; e is base of hyperbolic logarithm; x, y are current coordinates of axes in XOY coordinate system. Cutting edges are fixed on inner surface of concave curved portions of guiding shield.

EFFECT: uniform distribution of nutritive mixture components through the entire volume of pile owing to intensified nutritive substrate mixing process and elongated fibrous materials grinding process and, accordingly, effective controlling of weed plant seeds and pathogenic microorganisms of substrate.
