The present invention relates to a fertilizing apparatus, and more particularly, the present invention relates to a liquid fertilizer apparatus for use with a water sprinkler system.
Water sprinkle system has become quite common in lawns, parks, fields, and like for watering the plants, lawns, and crops. Water sprinkle systems are generally used in commercial and residential places for watering lawns and plants. The water sprinkle systems have several advantages, such as watering the lawn and plants can be automated and wastage of water is very less.
Besides, watering, the fertilizers must also be periodically applied to lawns, plants, and crops. In the case of crops, fertilizers are frequently used, specifically in the fast-growing phase of the crop. There are many methods known in the art for the application of fertilizers.
However, a desire is always there for an improved method and apparatus that is economic, efficient, and easy to use.
The following presents a simplified summary of one or more embodiments of the present invention in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments and is intended to neither identify key or critical elements of all embodiments nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.
The principal object of the present invention is therefore directed to a liquid fertilizing apparatus that can be incorporated into a water sprinkler system.
It is another object of the present invention that the liquid fertilizing apparatus can be retrofitted into an existing water sprinkler system.
It is still another object of the present invention that the liquid fertilizing apparatus is economic to manufacture.
It is yet another object of the present invention that the rate of fertilizer application can be controlled.
It is a further object of the present invention that the liquid fertilizing apparatus allows a selectable quantity of the liquid fertilizer to be automatically sprayed in commercial or residential lawns and gardens.
It is still a further object of the present invention that the liquid fertilizer apparatus can also be used to apply insecticides or herbicides.
It is an additional object of the present invention that the liquid fertilizing apparatus is easy and economical to maintain.
In one aspect, disclosed is a liquid fertilizer apparatus that can function in combination with an existing water sprinkler system. The liquid fertilizer apparatus can include a container for holding the liquid fertilizer, the container has a base and a wall that upstands from a periphery of the base, wherein the base and the wall define an inner volume of the container. The top of the container can be open and cover by a cap. The wall of the container can have an inlet and an outlet, wherein a venturi tube can sealably bridge between the inlet and the outlet of the container. The supply line connecting the water source to the water sprinklers can be connected in series with a water control valve, the venturi tube, and at least one sprinkler head. The venturi tube can have one or more slots, wherein water passing through the venturi tubes undergo a change in pressure resulting in the formation of a partial vacuum. The partial vacuum through one or more slots of the venturi tube can draw liquid fertilizer from the container into the venturi tube, wherein the liquid fertilizer can mix with the water, and the mixture of the liquid fertilizer in the water can be dispensed through sprinklers.
In one aspect, the liquid fertilizing apparatus can be installed between an output of a water source and an input of one or more sprinkler heads. Preferably, the liquid fertilizing apparatus can be installed between an output of the water control valve and the input of at least one sprinkler head. When a stream of water flows through the venturi tube, the water due to change in pressure results in a partial vacuum within the venturi tube that functions as an aspirator. The negative pressure or partial vacuum causes the liquid fertilizer in the fertilizer container to be drawn through one or more slots and into the flowing stream of water.
To further enhance the design of the liquid fertilizing apparatus, an inlet end of the venturi tube can be attached to an inlet locknut, a one-way control valve, and a rotating union that can be attached to the supply line connected to the water source. Likewise, an outlet end of the venturi tube i.e., the flared end can be connected to an outlet locknut and a sprinkler tube adapter for connecting to the supply line connecting the sprinklers.
In one aspect, the liquid fertilizer can be any liquid fertilizer, natural or synthetic, known to a skilled person for use in lawns, plants, and crops, and includes solid fertilizers dissolved in water.
These and other objects and advantages of the present invention will become apparent from the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompanying drawings.

Disclosed is a liquid fertilizing apparatus that can be used in combination with a typical water sprinkler system for the application of liquid fertilizer in a lawn, plants, or crops. The liquid fertilizing apparatus can be installed in series and to function in combination with an existing watering system, wherein a quantity of liquid fertilizer can be infused into a flowing stream of water. A typical watering system 150, as shown in
Referring to
The top of container 12 can be open, and a cap can be used to cover the open top of the container.
Container 12 can have an inlet 20 and an outlet 22 made in the wall of the container. The inlet 20 and outlet 22 can be in a form of bosses that provides fluid communication between an inner volume of container 12 and the outside. The inlet 20 and outlet 22 can be on opposite sides, such as a common axis that can pass through the centers of inlet 20 and outlet 22.
On the bottom side of the container, 12 can be seen a nozzle 24 that may be fluidly connected to a large vat, that may contain the liquid fertilizer. The nozzle 24 shown in
The flared end can be connected to the supply line that connects to the water source or the water control valve. The water control valve can control the amount of water that enters the venturi tube 26. Similarly, the narrow end of the venturi tube 26 can be connected to the supply line connecting the sprinkler heads. Fasteners, such as locknut and sprinkler tube adapter can be used to connect the narrow end of the venturi tube 26 to the supply line of the sprinkler head. The flared end can also be connected to the supply line using fasteners, such as locknuts. Additionally, a fertilizer metering control knob and a backflow control valve can also be used to control the flow of water, and thus controlling the amount of partial vacuum created in the venturi tube 26, and thus the amount of liquid fertilizer drawn into the venturi tube 26. The venturi tube 26 can be sealably fit into the inlet 20 and outlet 22. Embodiments of the “U.S. Pat. No. 7,395,978B2” including units connected in parallel are within the scope of the present invention. Fasteners explained in “U.S. Pat. No. 7,395,978B2” such as rotating union can be used to connect the disclosed apparatus to the supply lines and connecting the disclosed apparatuses as units in parallel to a water inlet manifold. Shut-off valves described in “U.S. Pat. No. 7,395,978B2” can also be used to allow each fertilizer container 12 to be individually operated.
While the invention has been described in complete detail and pictorially shown in the accompanying drawings it is not to be limited to such details, since many changes and modifications may be made to the invention without departing from the spirit and the scope thereof. For example, the disclosed apparatus can be designed to be placed underground or above ground and can be color-coded to indicate the liquid capacity of the fertilizer container, and can include a transparent window on container 12 to show the quantity of fertilizer remaining in container 12. Hence, it is described to cover any and all modifications and forms, which may come within the language and scope of the claims.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
