The justification for colter spreader configuration selected for broadcast seeding and mineral fertilizer application

Abstract

The aim of this work the graphical regularities of the fertilizer pellets outflow through a flattened cone have been considered in an effort to justify the configuration of universal colter spreader which would provide even distribution of the grass and grain seeds, and mineral fertilizer pellets within the soil. It has been determined that to achieve the granular materials’ uniform outflow in the direction transverse to travel speed over the colter spreader surface its elliptical cross-section is required. To this effect the section plane should be directed perpendicular to travel speed, cross over all cone generators at an angle between it and central axis of the latter other than π/2.
