Mathematical Modelling and Designing of a Universal Conical Spreader for Granular Material

Abstract A universal conical spreader for uniform distribution of granular fertilizers and seeds grain crops, grasses is proposed. The developed designed subsurface application above-mentioned materials using seed drills can be used as a passive distributor in wide variety applications. methods theoretical mechanics descriptive geometry, particularly the method replacement projection plane have been applied to arrive at design cone – shape spreader. parametric equation was derived truncated part cone, which an ellipse. unique cone-shaped has truncating form direction transverse movement seeder. In order determine interval variability parameters more precisely, analysis carried out Mathcad-15 software. results research were confirmed laboratory field conditions. width distribution, uniformity, stability studied most effective design. smallest values non-uniformity instability material experimental coulter are reached factors D = 117–119 mm, h 17–18 H 32–35 mm.
