## Background
FIELD OF THE INVENTION
The invention relates to the devices for oxygen enrichment and/or atmospheric air enhancement in a soil, and specifically, invention relates to the devices and apparatus for oxygen/air enrichment/enhancement in the agricultural and/or garden soil, and more specifically for oxygen and/or atmospheric air enrichment/enhancement in the agricultural or garden soil in the area of the plant's roots.
BACKGROUND OF THE INVENTION
There are known many methods and devices for oxygen enrichment of the soil. These methods and devices provide increasing of the amount of the atmospheric air or pure oxygen in the sub-surface soil.
The atmospheric air in the soil profile removes accumulated unwanted gases, and provides more oxygen than otherwise would tend to be present.
It is known that the air in the soil profile will change moisture content and temperature. It is understood that it is important to additionally control gas constituents in the subsoil, such as the amounts of oxygen, carbon dioxide, methane and hydrogen sulfide. It is found that when the atmospheric air/oxygen is presented at the rootzone in the soil, there is enhanced root system development, better growth, better resistance to disease, etc.
It is also known that here is much commercial interest in promoting good vegetation growth. It is very important to obtain optimal growing conditions in the root are. It is known and well recognized that plant's life depends upon the character of the soil surrounding the roots. It has become increasingly recognized that it is advantageous to provide a soil with appropriate aeration.
Provision of air has been sought by various means. In one simple widely used procedure, small (one-half inch diameter) holes are created in the surface of the field, by drilling or punching with a machine.
While simple, this process is relatively inefficient since air enhancement takes place until the natural closing of the drilled holes under the natural atmospheric forces, etc.
This is typically accomplished by a mechanical system involving air moving machinery connected to an array of sub-surface pipes installed as an adjunct to a permeable layer of the soil profile.
For instance, U.S. Pat. No. 5,433,759 to Benson describes a ventilating system wherein an air pressure is applied to the piping system, to thereby affect the conditions in the layered soil and turf. However, results obtained will vary according to the morphology (structure) of the soil. In practice, air has been periodically injected in the sub-surface piping system according to the subjective judgment of the user of the system.
Since there has been no particular efficient mechanism or systematic way for air/oxygen enrichment of the soil in the root areas, such tendency heretofore has not found wide application in the agriculture and/or gardening. Another drawback is a significantly expensive induction mechanical system(s) of the enforceable enrichment of the soil.
The similar principle has been used in the U.S. Pat. No. 6,018,909, where is the air injecting apparatus creates the pressure differential in the soil. The numerous pipes are installed horizontally underground beneath the vegetation's roots surface through the soil.
Additionally to the noticed drawback hereinabove regarding significantly expensive equipment, the pressure method(s) provide an oxygen in excess to atmosphere by connecting an oxygen source to the air pressure supply, but as it is known, any excess oxygen does not necessarily speeds the process.
Another U.S. Pat. No. 5,037,240, provides the wick drains used alone or in combination with the porous or slotted pipes depending on the type of treatment to be applied to the particular area and particular soil conditions. The tubing or pipes is used in soil to enhance the air for desired sub-surface condition.
The drains may be used to deliver the oxygen. The wick drains are installed at a close spacing configuration. The existing track excavators are used to install the wick drains. The method also employs the tubes and pipes of porous configuration to inject or pump an oxygen. This method has the same deficiencies, as the methods and apparatus/devices described hereinabove.
The multi-pipes traces are also used in the U.S. Pat. Nos. 5,120,158 and 5,542,208.
Regarding U.S. Pat. No. 5,120,158, a pipe arrangement includes a surface layer and a filter layer beneath the surface layer. In the filter layer, there is situated an arrangement of pipes, divided into several sections. In each section, there are numerous pipes to circulate warm air into it. These pipes are connected at intervals by their ends to a distribution pipe and these in their turn at intervals by their ends to a main pipe, which is finally connected to blowing machinery by means of a feed pipe. The main pipes are located on the long side of the field and they are connected at regular intervals to distribution pipes, which extend from the side of the field from main pipe to essentially the center of the field. All the distribution pipes of the same main pipe are connected to multi-purpose pipes, which run in the same direction as the main pipe.
The soil area (field) is divided into four separate pipe network sectors. A blower apparatus, in which there are also heating cells to warm the air to be blown, is located at the side of the field. A feed pipe is communicated from blower to the main pipe of the pipe network sections. Main pipes have valves on each by means of which it is possible to blow air or cut off the air blowing to each section separately.
According to the description of the U.S. Pat. No. 5,542,208, the mobile unit comprises a blower connected into a duct network beneath a use site/field to induce a flow of air upwardly through the soil and subsoil of the use site. The blower is equipped with a four-way reversing valve so that the flow of air moving through the duct network can be reversed to pull air downwardly through the soil profile during certain climatic periods. The four-way flow reversing valve contains four control valves mounted in a bridge configuration. The discharge side of the blower is connected to the unit by line. One pair of the bridge legs is connected to the supply line while the opposite pair of legs is attached to an air line that communicates with the surrounding ambient. The exit to the bridge between legs is connected to the inlet side of blower by means of return line. When one pair of valves is closed and the other pair of valves is opened, ambient air is delivered to the inlet side of the blower and is pumped into the duct network. The air is passed through the lines of the duct network and uniformly distributed. The blower delivers low pressure air at a high enough volume such that the air is pushed upwardly through the soil and subsoil into the surrounding ambient. Air moving upwardly through the green is used to aerate the soil.
The apparatus/unit by these two patents include the expensive equipment, and the pressure (“blowing”) method(s) can provide an oxygen in excess to atmosphere by connecting an oxygen source to the air blowing machinery.
Thus, the known devices are expensive, and in order to provide the soil oxygen enrichment include an expensive mechanical blowing/pumping means coupled to the underground traced expensive pipes' system.
The mentioned hereinabove methods and devices do not loosen the soil for natural enhance of oxygen in the sub-surface area near the plant's root at the rootzone.
Therefore, the mentioned known methods and devices have the described above deficiencies which are eliminated in the improved device for oxygen enrichment of a soil.
Considering that most plants always require the enhancement of the oxygen concentration in the soil's rootzone, the atmospheric air, delivered by the improved device, into the loosened (by the improved device) sub-surface soil area at the rootzone will provide the faster growth of the plants/vegetations.
Also, it is more effective to delivery the atmospheric air into the loosened soil.
Additionally, the improved device provides the better condition (e.g., the loosened soil) of the sub-surface soil for the plant's root development.
While the mentioned above prior art fulfill their respective, particular objectives and requirements, the mentioned prior art inventions do not disclose, teach and/or suggest the device for oxygen enrichment of a soil including the means for loosening of the sub-surface soil at the rootzone of the vegetations.
Those skilled in the art will readily observe that numerous modifications and advantages of the improved device for oxygen enrichment of a soil may be made while retaining the teachings of the invention.
Thus, the known prior art do not provide the efficient, not expensive, and convenient device for oxygen enrichment of a soil according to the present invention substantially departs from the devices of the prior art.
OBJECT AND ADVANTAGES OF THE INVENTION
Accordingly, several objects and advantages of the present invention are to provide the improved device for oxygen enrichment of a soil:
It is object of the invention to provide an improved device which provides the enhancement of the oxygen in the soil for the vegetation root's growth development.
It is another object of the invention to provide an improved device which loosens the soil for the vegetation root's growth development.
It is another object of the invention to provide an improved device which loosens the soil for the oxygen and/or atmospheric air delivery into the soil.
It is further another object of the invention to provide an improved device with the increased efficiency of the vegetation's growth.
Still, further objects and advantages will become apparent from a consideration of the ensuing description accompanying drawings.

SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known prior art, the present invention provides an improved device for oxygen enrichment of a soil. As such, the general purpose of the present invention, which will be described hereinafter in greater details, is to provide the improved device providing a loosening of the sub-surface soil and delivery of the atmospheric air into the pores of the loosened air.
The improved device has many of the advantages of the oxygen enhancement in the sub-surface soil at the rootzone and many novel features that result in the efficient growth of the plants and vegetations, which is not anticipated, rendered obvious, suggested or even implied by any of prior art methods and devices for soil enrichment, either alone or in any combination thereof.
This invention, device for oxygen enrichment of a soil, provides the enhancement of the oxygen in the area of the root(s) in the sub-surface soil layer.
To attain this, the present invention generally comprises the perforated vertical tubular means pivotable in the vertical portion of the tubular connecting means, thereby providing by the soil loosening means a loosening of the sub-surface soil at the plant's rootzone. Also, the improved device includes the perforated horizontal tubular means, coupled with the vertical tubular means via tubular connecting means, which comprises the slots for unobstructed movements along the appropriate slots of the extended ends of the lower soil loosening means, and the handle means rigidly connected to the upper end of the vertical tubular means and intended for rotation of the vertical tubular means in the vertical portion of the tubular connecting means.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference now to the drawings, and particularly to FIGS. 1-6a, 6b-12a, 12b-14 thereof, an improved device for oxygen enrichment of a soil embodying the principles and concepts of the present invention.
The term “tubular” hereinbelow solely and/or jointly accumulate the meaning, for instance, of the “tube”, “pipe”, etc. Therefore, the use at least one of the terms does not exclude the other meanings for the used term, if otherwise not specified.
In the FIG. 1 are shown the improved device 1 inserted in the garden pot 2. Also, in the FIG. 1 are shown the soil 3 comprising the soil surface 4 and the sub-surface soil 5 including the rootzone 6, in which the root(s) 7 of the plant 8 are located.
The improved device 1 includes the handle means 9 and the vertical tubular means 10 comprising the apertures (perforation) 11, the first soil loosening means 12, the second soil loosening means 13 and the third soil loosening means 14. The improved device 1 also comprises the tubular connecting means 15, which includes the vertical portion 16 and horizontal portion 17, and two slots: the first slot 18 and second slot 27 (see, also, for example, FIGS. 6a, 6b), and the horizontal tubular means 24 comprising the apertures 11.
The handle means 9 is coupled with the upper end 19 of the vertical tubular means 10. The handle means 9 can include the apertures/perforation too (not shown, e.g., apertures 11 or alike and/or other types of openings, for instance, for the chemicals and/or soil nutrition supplementals delivery to the sub-surface soil in the rootzone). The rigid coupling of the handle means 9 with the upper end 19 of the vertical tubular means 10 can be provided by gluing to each other or by any other reasonable methods of their rigid connection to each other.
The first soil loosening means 12, the second soil loosening means 13 and the third soil loosening means 14 are located in the area of the lower end 20 of the vertical tubular means 10. The first 12 and third 14 soil loosening means are locate in the same plane (not shown), and are perpendicular to the second soil loosening means 13. The configuration of the first soil loosening means 12, the second soil loosening means 13 and the third soil loosening means 14 is conditionally shown in FIGS. 1-4, 6a, 8-10, 12a, 12b as the pins passing through the vertical tubular means 10 perpendicularly to the axis 50 (see FIG. 4) of the vertical tubular means 10 in such manner that their ends extend over outside surface 21 of the vertical tubular means 10 (the length “L” of the soil loosening means is bigger than the outside diameter “D” of the vertical tubular means 10, i.e., L>D [see FIG. 1]). The length of the extension of the ends of the tubular means 10 is not limited, but reasonably can be in the approximate range of 0.25 inch-2.0 inches for the purpose to loosen a soil, for example, in the typical garden pot. In FIGS. 1-4, 6a, 8, 10, 12a, 12b, 14 the diameter of the soil loosening means is shown approximately the same, but the diameter of each of them can be different. The reasonable diameter of the soil loosening means can be in approximate range of 1/16 inch-1⁄4 inch. Also, the soil loosening means 12-14 are conditionally shown in FIGS. 1-4, 6a, 6b, 8-10, 12a, 12b, 14 of the cylindrical configuration, but they can be of any reasonable configuration and form, for instance, of square or triangular forms, etc. (not shown) or of any reasonable irregular form/shape (not shown). The FIG. 12b illustrates a variant where the soil loosening means 12 have only one end extended from the vertical tubular means 10. If such configuration will have the soil loosening means 14, than the vertical portion 16 of the tubular connecting means 15 (FIGS. 1-3) or of the connection means 30 (FIG. 4) will comprise only one slot (e.g., the slot 18).
In FIG. 14 the second soil loosening means 13 is conditionally shown of two short pieces: first half 22 portion of the second soil loosening means and second half 23 portion of the second soil loosening means 13, but each soil loosening means can be presented by two halves (not shown). The soil loosening means of solid (not divided for two halves), as well as the soil loosening means of two halves configuration are rigidly coupled with the vertical tubular means 10 (e.g., tightly screwed into the wall of the vertical tubular means 10, glued or by any reasonable principles of the other rigid connections [not shown]).
As it is shown in FIG. 2, the horizontal tubular means 24 is inserted into the horizontal portion 17 of the tubular connecting means 15. The of inner surface 25 of the horizontal portion 17 of the tubular connecting means 15 should have enough tight contact with the outer surface 26 of the horizontal tubular means 24, or the inserted the horizontal tubular means 24 can have a rigid connection with the horizontal portion 17 of the tubular connecting means 15 (e.g., screwed, bolted, glued, welded, etc. depending on the materials of the horizontal tubular means 24 and tubular connecting means 15).
As it is understood from FIG. 6a, the ends of the third soil loosening means 14 are extended of the vertical tubular means 10. The one extended side of the third soil loosening means 14 freely passes through the first slot 18 and the other extended side of the third soil loosening means 14 freely passes through the second slot 27. The lower end 20 of the vertical tubular means 10 is not tightly inserted into the vertical portion 16 of the tubular connecting means 15. It means that the outside surface 21 of the vertical tubular means 10 does not have a tight friction with the inner surface 29 of the vertical portion 16 of the tubular connecting means 15, thereby providing free (unobstructed) pivoting movements of the lower end 20 of the vertical tubular means 10 inside the vertical portion 16 of the tubular connecting means 15. The rotation of the vertical tubular means 10 inside the vertical portion 16 of the tubular connecting means 15 is limited by the lengths of the first 18 and second 27 slots, wherein the extended ends of the third soil loosening means 14 make movements along the slots when the vertical tubular means 10 makes the clockwise and counterclockwise rotations inside the static position of the connected tubular connecting means 15 and horizontal tubular means 24. The clockwise and counterclockwise rotations of the vertical tubular means 10 can be provided by an operator (e.g., by gardener, etc.) by pivoting of the handle means 9. During the clockwise and counterclockwise pivoting movements of the vertical tubular means 10, the soil loosening means 12-14 loosen the sub-surface soil 5 at the rootzone area. The atmospheric air, containing the oxygen, passes through the apertures 11 into the loosened sub-surface soil 5, providing enhancement of air (oxygen) into the loosened sub-surface soil 5, thereby enriching the oxygen concentration in the area of the location of the plant's/vegetation's root(s).
It is understandable, that as depth of the sub-surface soil layer increases, the oxygen content of the soil is severely reduced. Aerating the soil with the improved device will enrich the soil with the oxygen during aerobic treatment. If it will be determined that an aerobic degradation of the soil is needed, the soil loosening, and as a result—the additional aeration, can be discontinued and as the available oxygen is utilized, anaerobic conditions will naturally recur.
The FIGS. 5, 6a, 6b, 7, 8, 9, 10, 11 illustrate the cross-sections of the appropriate tubular means. For example, the FIGS. 5 and 11 illustrate the locations of the apertures 11 in the vertical tubular means 10 and the horizontal tubular means 24 respectively, additionally to the depiction of the locations of the apertures 11 in the FIG. 2. For more details, the cross-sections are shown in a slightly increased scale.
Referring FIG. 3, the improved device comprises a combination of the horizontal tubular means 24 and tubular connecting means 15 as a whole solid (entire) piece of auxiliary tubular means 36.
According to FIGS. 12a, 12b and 13, the improved device can be presented without the horizontal tubular means 24, i.e., the improved device 1 (FIGS. 12a, 12b, 13) inserted in the garden pot 2 comprises: the handle means 9, vertical tubular means 10 comprising the apertures (perforation) 11, the first soil loosening means 12, the second soil loosening means 13 and the third soil loosening means 14, the tubular connecting means 15, which includes the vertical portion 16 and horizontal portion 17, the first slot 18 and second slot 27, the horizontal tubular means 24, the upper end 19 of the vertical tubular means 10, the lower end 20 of the vertical tubular means 10, and their appropriate sub-components and elements described hereinabove. As it is shown in FIGS. 4, 13, the connection means 30 has a different configuration than the tubular connecting means 15. Instead of the corner form of the tubular connecting means 15, shown in FIGS. 1-3, 8, and which is not coupled with the garden pot 2, the connection means 30, shown in FIGS. 4, 13, includes the bottom wall 31 comprising the auxiliary aperture 32 intended for the bolt 33 tightening by the nut 34 the bottom wall 31 of the connection means 30 with the bottom wall 35 of the garden pot 2. Instead of nut 34 the thread (not shown) in the auxiliary aperture 32 of the bottom wall 31 of the connection means 30 can be used for tightening (for a rigid connection) by the bolt 33 (or by a screw [not shown]) of the connection means 30 with the bottom wall 35 of the garden pot 2. It is understood, that any other reasonable threaded or not treaded coupling or rigid connections (not shown) can be used too. Also, the coupling (connection) of the vertical tubular means 10 with the garden pot 2 may be provided without tubular connecting means 15 or connection means 30, if the pivotability of the vertical tubular means 10 will be still provided (for instance, the lower end 20 of the vertical tubular means 10 can be unobstructedly pivotable in the bigger auxiliary aperture 32 of the garden pot 2, and can be fixed by washer 51 in order not to be pulled off the pot 2, as it is shown in FIG. 15, etc.).
It is understandable, that the apertures (perforation) 11 in the figures are conditionally shown of a circular configuration, but the square form apertures or triangular, rectangular, etc. forms of the apertures 11 can be used, as well as any reasonable irregular configuration and forms. Also it should be understood, that there can be any reasonable quantity of the apertures 11, and generalizing any and all possible modifications can be stated that the improved device includes at least one of a plurality of apertures. Additionally, the FIG. 6a depicts two slots 18 and 27 for the uninterrupted (not divided, entire) third soil loosening means 14, and FIG. 6b depicts two slots 18 and 27 for the interrupted (divided) third soil loosening means 14 for two halves (for two pieces): the first half (piece) 37 of the third soil loosening means 14 and second half (piece) 38 of the third soil loosening means 14, but the improved device can comprise, for example, three pieces (not shown) of the short soil loosening means installed (e.g., rigidly screwed, etc.) into the tubular wall 39 of the vertical tubular means 10 under the angle of 120° to each other (not shown). Under these circumstances, the vertical portion 16 of the tubular connecting means 15 or the connection means 30 will comprise the three slots (not shown) appropriately located under the same 120° to each other. Also, it is conditionally shown in FIGS. 1-4 three soil loosening means 12-14, but it can be reasonably less or more of them and under different reasonable distance from each other. Generalizing possible modifications, the improved device can comprise at least one of a plurality of soil loosening means and respectively at least one of a plurality of slots.
The handle means 9 can be of any regular geometric configuration (e.g., cylindrical, elliptical, square, triangle, etc. not shown]) or any reasonable irregular configuration and form (not shown).
The inner configuration of the horizontal portion 17 and respectively the outer configuration of the horizontal tubular means 24 can be of any reasonable regular geometrical form (e.g., square, triangular, rectangular, etc. [not shown]) or any reasonable irregular form/shape (not shown).
The some appropriate means in the device set (e.g., the tubular connecting means 15 and connection means 30) can be interchangeable.
As shown in FIGS. 1-4, the vertical tubular means 10, and as shown in FIGS. 1-3, the horizontal tubular means 24 are perforated throughout their length and can have variable perforations such that the diffused air added to the sub-surface soil. The diameter of the inner surface 28 of vertical tubular means 10 can be of reasonable size to provide durability of the thickness of the wall 39. These tubular means can also consist of uniform porosity flexible rubber (not shown). A determination of which configuration and material of the tubular means 10, 15 and 24 best meets the needs is based on the actual reasonability. The sizes of means of the improved device are varied or modified for different pot's sizes. The goal of the improved device is to create such loosen (by the soil loosening means) soil that the atmospheric air (oxygen), delivered to the sub-surface soil via perforated tubular means of the improved device, is allowed to enter all of the soil pores at a rate that is sufficient for aerobic treatment of the growing plants/vegetations.
The improved device can be installed to any desired reasonable depth or angle in the garden pot. The improved device provides a means of introducing atmospheric air (oxygen) into the sub-surface soil profile at the desired depth. The change of the soil profile from an anaerobic environment to an aerobic environment permits the treatment of sub-surface soils to any desired depth and does not require that any soil be removed from the garden pot for outside treatment.
Thus, significant cost savings from elimination of the expensive equipment and materials are readily obtained. The improved device can also provide the delivery to the sub-surface soil (via perforated tubular means of the improved device or opening [not shown]) the needed biochemicals and soil nutrition supplementals.
The improved device realizing delivery of the atmospheric air/oxygen into pores of the loosened sub-surface soil at the rootzone is significantly needed to provide more efficient enhancement of oxygen for the plant's/vegetation's roots.
