Apparatus and methods are provided for a fluid fertilizer distributor (10, 200, 300, or 400) for distributing fluid fertilizer conducted from a supply vessel (11) to each of a plurality of applicator lines (44). The fluid distributor may regulate a fluid fertilizer flow rate by selectively moving a flow restrictor (50, 250, 350, or 450) relative to the distributor housing. The distributor housing may include a supply inlet port (12, 212, 312, or 412) and a plurality of distributor outlet ports (16, 216, 316, or 416) each for fluid communication with a respective one of the plurality of applicator lines (44). The fluid distributor may separate the fluid fertilizer into a plurality of fluid flow paths prior to reducing the pressure in the fluid to avoid gas flashing or vaporization prior to separation. Thereby, fluid distribution may be effected upon a substantially liquid fluid within the fluid distributor, which may result in substantially uniform fertilizer application, with reduced rate variation between applicator lines. The flow restrictor (50, 250, 350, or 450) may be substantially ring shaped and positioned on an external surface of the distributor housing, or substantially cylindrical shaped and positioned substantially internal to the distributor housing. The fluid distributor may provide for substantially infinitely regulating the application rate between a fully closed position and a fully open position. Rate regulation may be performed manually or by programmable controller.
Une description d'un appareil et de méthodes de distribution d'engrais (10, 200, 300, ou 400) est fournie relativement à un distributeur d'engrais liquide, lequel engrais est distribué à partir d'un réservoir (11) vers chacune de plusieurs conduites applicatrices (44). On peut régler le débit d'engrais liquide du distributeur de liquide en déplaçant un réducteur de débit (50, 250, 350 ou 450) par rapport au boîtier du distributeur. Ce dernier peut comprendre un orifice d'entrée d'alimentation (12, 212, 312 ou 412) et plusieurs orifices de sortie de distribution (16, 216, 316 ou 416) qui sont chacun reliés à une des conduites applicatrices. Le distributeur de liquide peut répartir l'engrais liquide en plusieurs voies d'acheminement avant de réduire la pression du liquide afin d'éviter le gas flashing ou la vaporisation avant la séparation. Donc, la distribution du liquide peut être effectuée avec un liquide très fluide dans le distributeur de liquide, ce qui résulte en une application uniforme d'engrais, avec moins de variations de débit entre les conduites applicatrices.
