  • Patent number: 4793743
    Abstract: The air seeder normally passes the contents of its hopper through metering devices that regulate the volume of materials moving into the transporting air streams of the machine, but the hopper is also provided with a series of normally closed drainage apertures which may be selectively opened when it is desired to rapidly dump the hopper contents instead of relatively slowly metering them to the air streams. When the apertures are opened, the hopper contents bypass the metering devices and gravitate directly into the air streams which can be quickly and easily diverted to a cyclone separator that exhausts the air from the streams and concentrates the particles for collection or storage.

  • Patent number: 4717289
    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.
