For use with an air seeder for distribution of seed to a agricultural implement by pneumatic conveyance is a unique seed-centering and distribution system. The primary conveyance tube which is adapted to receive metered amounts of fertilizer and/or seed or granular herbicide is equipped with a plurality of internal sloped annular rings as well as a series of internal baffles. The internal baffles are particularly adapted for dividing the seed stream through a right angled turn from the horizontal to the vertical. The sloped annular rings project further into the conveyance tube on their downstream side than on the upstream side. Interestingly enough, it has been found that much less power is required to center and evenly distribute the seed with this device than the prior art devices. Moreover, damage to delicate seed is greatly reduced. |
