  • Patent number: 7318557
    Abstract: A rotary distributor is for use in spreading solid particles and/or liquid from an agricultural machine. The rotary distributor comprises a round distributor having outlet holes arranged peripherally in the horizontal bottom of the housing and connected to outlet pipes 3, a first supply pipe 4 arranged centrally in the bottom of the distributor housing 1 for the supply of liquid under pressure and connected to a vertical, rotatably supported hollow rotor shaft 5 in flow communication with a first transverse hollow rotor arm 6 which has at least one angled, and downward-directed nozzle 7 that is level with the outlet holes 2. The distributor housing further comprises a means 10, 11 for introducing and distributing solid particles such as seed corn.

  • Patent number: 5462232
    Abstract: The rotating liquid distributor includes a circular distributor housing with an upwardly open annular channel. The channel bottom has spaced outlet openings at an even mutual distance. A supply pipe for liquid under pressure is centrally mounted in the distributor housing and is connected to a vertical, rotatably mounted hollow rotor stem with an upper transveral hollow rotor arm. Downwardly slanted nozzles extend from the rotor arm, flush with the outlet openings to produce a turning moment through the supply of liquid under pressure. The downwardly slanted nozzle is surrounded by a screen with an upside down U-shaped cross section. The screen has sidewalls that extend down into the annular channel on each side of the downwardly slanted nozzle in order to catch liquid splashed. A transporting roller which fills out the cross section of the annular channel, is fastened by a draw bar to the rotor arm.
