Abstract

Abstract A flow distributing device is described which is useful for effecting even distribution of a liquid from a central source to a plurality of conduits at variable flow rates. The device comprises a distributor housing with a plate bearing connecting means to a plurality of conduits. The connecting means are distributed on the plate on a predetermined pattern while a second plate is positioned in the assembly between the housing and the plate bearing the connecting means. This latter plate is movable between a plurality of positions and bears a series of apertures for each of the multiple connections, which apertures have varied cross-sectional area. The apertures are similarly disposed on the movable plate in a predetermined pattern so that at any position of the movable plate in the assembly, all of the multiple connections will be in communication with the housing through apertures of equal cross-sectional dimensions. The distributor is particularly useful in combination with a liquid fertilizer distributor. These distributors comprise a storage tank in which the liquid fertilizer is contained, pump means which removes liquid from the storage tank and forces the liquid under pressure to the flow distributor and a plurality of tubing lines connected to the multiple connecting means of the flow distributor, each of the tubing means passing to liquid discharge means. The flow rate or fertilizer application rate for this device is controlled by the displacement or revolution speed of the pump and the settings on the pumping rate are correlated with the settings of the movable flange to provide flow distributing orifices of small cross-sectional area with the low pump rates and proportionally larger apertures with greater rates.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 240 words
In a liquid fertilizer applicator adapted to be used for distribution of liquid fertilizer in a field and comprising a storage vessel for liquid, a transverse boom extending laterally on said applicator, a plurality of liquid discharge means regularly and evenly spaced on said transverse boom, distribution means connecting the said storage vessel to each of the said liquid discharge means, said distribution means including as the improvement thereof a flow distributing device which comprises a housing, connection means associated with said inlet port for attachment thereto of a conduit, at least one wall of said housing being provided with a plurality of apertures disposed in a regular pattern therein, connection means for attachment of conduits to each of said apertures, a plate for use in association with said wall of said housing which is movable between a plurality of positions in said housing and which is provided with a plurality of sets of apertures of regularly varied cross-sectional area, each of said sets being disposed in said plate with the same pattern as the pattern of said apertures in said wall of said housing and adapted to be positioned in fluid transferring orientation between the interior of said housing and said apertures in said wall thereof with apertures of equal cross-sectional area of said flange being associated with each of said apertures in said wall of said housing, and means for fixed adjustability of the position of said plate.
Claim 2
Dependent Claim 240 words
In a liquid fertilizer applicator adapted to be used for distribution of liquid fertilizer in a field and comprising a storage vessel for liquid, a transverse boom extending laterally on said applicator, a plurality of liquid discharge means regularly and evenly spaced on said transverse boom, distribution means connecting the said storage vessel to each of the said liquid discharge means, said distribution means including as the improvement thereof a flow distributing device which comprises a housing, connection means associated with said inlet port for attachment thereto of a conduit, at least one wall of said housing being provided with a plurality of apertures disposed in a regular pattern therein, connection means for attachment of conduits to each of said apertures, a plate for use in association with said wall of said housing which is movable between a plurality of positions in said housing and which is provided with a plurality of sets of apertures of regularly varied cross-sectional area, each of said sets being disposed in said plate with the same pattern as the pattern of said apertures in said wall of said housing and adapted to be positioned in fluid transferring orientation between the interior of said housing and said apertures in said wall thereof with apertures of equal cross-sectional area of said flange being associated with each of said apertures in said wall of said housing, and means for fixed adjustability of the position of said plate.
Claim 3
Dependent Claim 27 words
The applicator of claim 1 wherein said fluid distributing device has a generally rectangularly shaped housing and said plate is slidably movable between said plurality of positions.
Claim 4
Dependent Claim 23 words
The applicator of claim 1 wherein said housing also contains a port in its lower wall for draining the contents from said housing.
Claim 5
Dependent Claim 34 words
The fertilizer applicator of claim 1 wherein said housing is generally circular and said plurality of apertures are disposed in a circular pattern with said plates being rotatably movable between said plurality of positions.
Claim 6
Dependent Claim 31 words
The applicator of claim 1 including pump means in the flow distribution system and adapted to withdraw liquid from said storage vessel and supply said liquid to said flow distributing device.
Claim 7
Dependent Claim 39 words
The device of claim 1 wherein each of said multiple conduit connecting means is connected to a conduit which extends to each of a plurality of liquid discharge means which are regularly and evenly spaced on a transverse boom.
Claim 8
Dependent Claim 42 words
The device of claim 6 wherein said injection means comprises shanks that are resiliently carried by said boom and adapted for being dragged beneath the surface of the ground and associated therewith a discharge conduit in fluid communication with said multiple conduits.
