Abstract
The farm implement for distributing particles such as seeds or granular fertilizers has an apparatus for splitting a single particle-entraining air stream into a plurality of individual streams containing uniform and randomly divided quantities of particles. The apparatus has a horizontally disposed corrugated pipe in downstream communication with the conduit for providing a uniform flow of particles to a horizontally disposed, tubular, stream splitting distribution body. The distribution body has a transition section that progressively and symmetrically changes in a downstream direction from a circular configuration toward a generally flat, rectangular configuration, a generally flat transfer section that leads from the transition section and spreads symmetrically laterally outwardly in a downstream direction, and a single layer of generally horizontally disposed outlet tubes at the downstream end of the transfer section. The distribution body flattens and widens the stream from a generally circular in crosssection stream entering the circular inlet to a generally shallow and wide uniformly distributed stream that flows into the entry apertures of the layer of outlet tubes wherein…
