<p>A rotating liquid distributor, comprising a circular distributor housing (1), consisting of an upwardly open annular channel (1a), in whose bottom there are spaced outlet openings (2) at an even mutual distance. A supply pipe for liquid under pressure is centrally mounted in the distributor housing (1) and is connected to a vertical, rotatably mounted hollow rotor stem (5) with an upper transversal hollow rotor arm (6) with downwardly slanted nozzles (7), flush with the outlet openings (2) to produce a turning moment through the supply of liquid under pressure. Nozzle (7) is surrounded by a screen (8) with an upside down U-shaped cross section with sidewalls (8b) which extends down into the annular channel (1a) on each side of nozzle (7) in order to catch liquid splashed. A transporting means (9) which fills out the cross section of the annular channel (1a) is fastened by means of a draw bar (10) to rotor arm (6). Thereby any particle deposits in the annular channel will loosen and liquid leaks will be transported to and forced through the outlet openings (2). 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. Thereby there is achieved even fertilization by using said liquid distributor with connected equipment when driven across uneven fields.</p> |
