ECONOMICAL ASPECTS OF INFLUENCING FACTORS ASSURING NECESSARY PRESSURE DIFFERENCE OF A SEED PNEUMATIC DISTRIBUTING DEVICE WITH A DRUM

Abstract

An ideal seed distributing device must realise a dosage seed by seed, without empty spaces. Usually, a good distribution device works between admissible limits. In a seed pneumatic distributing device the catching force to keep seeds on distributing orifices depends directly of pressure difference. This paper presents a relation to establish the necessary pressure difference for an optimal seed distribution process of a pneumatic device according with constructive and functional parameters and seed characteristics.
