SOLID FERTILIZER SPREADER Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: invention relates to mechanical spreaders of solid fertilizers over surface of field. Blade rotors of spreader are installed in bottom part of body along its longitudinal axis and are enclosed by cylindrical housing contacting through their side surfaces. Housing are provided with charging and distributing ports arranged in lower part of housings and made in form of separate sections diverging from center of body to its front and rear walls. Charging ports are arranged in upper part of housing starting from line of their contact and they occupy one quarter of surface, being divided by vertical divider arranged in between over entire length of body. Separating rings are installed inside housings in place of bending of distributing ports. Angle between tangential line drawn to surface of housing in point of beginning of slot of distributing port in direction of rotation of rotors and vertical changes from 0 to 135° from first section of distributing port arranged in center of body to last sections adjoining front and rear walls.

EFFECT: simplified design of spreader, reduced power intensity of process, improved uniformity of distribution of fertilizers over field surface.
