Justification form of the pneumaticseed drill distributor

This article presents the results of experimental studies to determine the rational form of horizontal pneumatic seed distributor. The studies revealed that the shaped distributor with adjustable partitions shape more adapted to the sown culture that expressed in the presence of partitions adjustment of rotation angles, and continuously tapering shape of the air channel. The results of the research showed that the highest rate of uniformity of seed distribution by the coulters figure corresponds to the distributor with adjustable partitions.
