It relates more specifically to the arrangement of devices of the type in question with a view to meeting the different practical requirements better than present devices, in particular to provide for rapid and easy assembly of large sprayer lines from economical elements, and permitting very rapid adjustment of the hourly liquid spray discharge to all possible conditions.
An important feature of the invention consists of the arrangement, in a common pressurized liquid inlet passage, upstream of a distributor consisting of at least two branches each connected by a separate valve to a spray nozzle, of a common outlet valve loaded by a calibrated spring to oppose liquid flow when the pressure is not sufficient to cause the spray, or to prevent dripping of the liquid contained in the upstream pipes at the time of closing of a main valve to protect the vegetation from burning.
In another important feature of the invention which may be used as a separate unit with a device of the type in question provided that it comprises downstream of a single passage, a distributor consisting of at least two branches each connected by a separate valve to a spray nozzle the upstream end of the said passage is connected to the saddle of a connector ring clamp fastening the device opposite a radial port around a spray liquid feed and support pipe.
In the latter case the axes of the spray nozzles are advantageously located in one plane perpendicular to the axis of the connector ring clamp.
In a preferred embodiment applicable also to devices without connector ring clamp the axes of the spray nozzles diverge to provide for geometrically separate sprays.
In the case of a device comprising connector ring clamps the axes of the spray nozzles are divergent and parallel to radii of the circle circumscribed in the clamp.
In another advantageous embodiment of the invention the nozzles produce flat sprays called flat pencil sprays extending in substantially parallel or divergent planes.
The attached drawing illustrates an example clarifying the invention, its features, and the advantages derived therefrom.
FIG. 1 is a front elevation, partly in section and partly as an external view, of an agricultural spray device based on the invention.
FIG. 2 is a side view of the same device, partly in axial section along ll-ll (FIG. I) and partly as an external view.
FIG. 3 is a perspective view of the same spraying device on a smaller scale.
FIG. 4. is a front elevation of a spraying device based on a modification of the invention.
FIGS. 5 and 6 are views similar to FIG. 2 of spraying devices based on two modifications.
If it is desired to conduct agricultural spraying with a liquid insecticide and/or fungicide, or with liquid fertilizers with a mobile system, the hourly discharge must sometimes be adjusted to the liquid used and to the particular local conditions.
Since the hourly discharge of a spray nozzle can only be adjusted within very narrow limits without interfering with the correct operation of the nozzle, it was considered useful to mount individually disconnectible nozzles along the same line.
Therefore, groups of nozzles capable of spraying at different discharge rates can be associated cyclically, and the said groups can be operated separately or in a plurality of groups to obtain several ranges of hourly discharge rates.
The invention provides for the production of groups of nozzles capable of operating in this manner in the most economical form possible and capable of being mounted practically and easily along spray lines consisting substantially of support and liquid spray feed pipes 1.
Each device comprises a body including a saddle portion 6 adapted to be clamped on the pipe 1 by a collar 7 in front of a radial port 8 provided in the said pipe, in such manner that this port 8 may communicate with a passage 2 formed in the said body. The body is integral with a transverse branch having a longitudinal bore which extends both sides of the plane of passage 2 as illustrated at 3 and 3a. A valve such as 4 is slidably mounted in each end of bore 3-3a to control nozzles 5, 5a respectively, supported by tubular nozzle carrying portions depending from the above-mentioned transverse branch.
To facilitate the assembly of the spraying device on a pipe 1 provided with a row of ports 8 variably spaced along a generatrix, the said pipe is provided with a centering and coupling nipple 9 projecting into the lower surface of saddle 6 and surrounded by a toric packing 10.
To assemble the spray line the nipple 9 of a device of the invention is introduced into one port 8, and peripheral packing 10 is applied to the edge of port 8 to form a seal when saddle 6 is in contact with pipe 1. Strap 7 is then pivoted on one side about a pin 11 around the pipe, and locked on the other side of the saddle by a screw 12.
Since spray products are usually expensive it is desirable to avoid flowing or dripping of the liquid contained in the pipes l of the line by gravity through the nozzles 5 and 5a of the device on temporary interruption of the spraying operation. For this purpose, according to another important feature of the invention, upstream of the two branches 3 and 3a of the distributor, common pressurized fluid inlet passage 2 is provided with a common outlet valve loaded by a calibrated spring 13 (FIG. 2) capable of opposing the liquid flow between passage 2 and the branches 3 and 3a of the distributor when the liquid pressure drops after the pressurizing pump has been stopped and becomes insufficient to provide for correct spraying by nozzles 5 and 5a in order to protect the vegetation from burning because of the dripping of the pipes during interruptions in the operation.
The outlet valve common to two or more spray nozzles 5, 5a, etc., provides for a substantial economy in the production of the device of the invention.
In the case illustrated the said common valve is provided on the side of the body of the device with an externally threaded flange I4 connected directly to the branches 3 and 3a of the distributor, and extending coaxially around a sleeve 15 connected individually to common inlet passage 2 and whose free edge is flush with that of flange 14.
The annular end faces of flange l4 and sleeve are covered by a natural or synthetic rubber diaphragm l6 clamped along the periphery by a cap 17 fixed by a ring 18 screwed on flange l4.
The said valves may of course consist also of other known means such as control lever valves or the like.
The spraying device of the invention can be manufactured very simply, for example, by molding, particularly by injection molding of plastic material, the axes of the spray nozzles being arranged in one plane perpendicular to the axis of the saddle 6 and strap 7 of the coupling clamp.
To avoid'interference among the spray jets issuing from nozzles 5 and 5a the said jets are advantageously flat pencil" jets 22 and 22a extending in substantially parallel planes as indicated diagrammatically in FIG. 1 for example.
According to another important feature of the invention spray jet interference is avoided even if the jets are conical turbulance jets by the provision of a divergence of their pattern axes 23 and 23a as is the case in the modification represented in FIG. 4.
lt will be observed that even if the axes of the spraying patterns 23 and 23a are not located in one plane perpendicular to the axis of pipe 1 the said axes can always be oriented parallel to a radius of the said pipe, and the device may be made adjustable by any known means to vary the divergence angle.
The device represented in FIG. 5 differs from that described above in that it comprises opposite coaxial coupling ends 24 and 25 connected to a single branch passage (not represented) having the same function inside the device as passage 2 in FIGS. 1 and 2.
Coupling ends 24 and 25 are connected to flexible hoses 26 and 27 to similar spraying devices, and annular clamps 28 and 29 are combined with annular clamps 28a and 29a fastening the device to a support bar 30.
The device represented in H0. 6 differs from that of FIG. 5 in that clamps 28a and 29a are replaced by a titting 31 fixed directly to the device, for example by a screw 32.
It is understood that the above description is supplied only as an example which does not restrict the scope of the invention which does not exclude substitution of any other equivalent means for the described structural details.
