PCT No. PCT/No92/00076 Sec. 371 Date Oct. 15, 1993 Sec. 102(e) Date Oct. 15, 1993 PCT Filed Apr. 15, 1992 PCT Pub. No. WO92/17996 PCT Pub. Date Oct. 29, 1992.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. Thereby any particle deposits in the annular channel will loosen and liquid leaks will be transported to and forced through the outlet openings. Accumulation of liquid in the lowest portion of the annular channel is avoided, through a slant position of the liquid distributor, and an even distribution of supply of liquid to the outlet openings is achieved. An even fertilization is thus achieved through the use of the liquid distributor with connected equipment when driven across uneven fields. |
