Abstract
"COMBINATION SEEDER AND FERTILIZER SHOVELS FOR AIR SEED-ING DEVICES"
ABSTRACT OF THE DISCLOSURE
Conventionally, seeding takes place after broad-casting of fertilizer or after side banding of the fertil-izer takes place. The former is inefficient and wasteful and the latter is of course inaccurate as it is difficult to locate the fertilizer in correct relationship to the seed. The present device comprises a shovel which in-cludes a plurality of seed outlets at the rear thereof and a plurality of fertilizer shanks depending from the underside of the shovel and having fertilizer outlets at the rear thereof and being situated longitudinally between the seeding outlets. The seed and fertilizer outlets are connected via manifolds to an air fertilizer and seeding device. This enables seed to be placed at one level and fertilizer to be side banded accurately at another lower level than the seed in one operation.

Description
"COMBINATION SEEDER AND FERTILIZER SHOVELS FOR AIR SEED-ING DEVICES"
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in the placing of fertilizer and seed in the correct relationship one to the other to obtain the maximum growth benefit.
Conventionally, fertilizer is either broadcast upon a field whereupon the seeding takes place in a con-ventional manner. This is of course wasteful as much of the fertilizer does not have any effect upon the seed.
A more common method is to seed the field in a conventional manner after fertilizer has been placed by side banding. If accuracy can be maintained, the seed is placed in the correct relationship relative to the fertil-izer but this is of course extremely difficult to accom-plish accurately and easily.
SUMMARY OF THE INVENTION
The present invention overcomes disadvantages inherent with conventional methods and is particularly adapted for use with air seeding devlces.
In accordance with the invention there is pro-vided a shove assembly for use with air seeder and fertil-izer devices and comprising in combination a shovel for mounting upon an implement shank, a fertilizer feed conduit extending from said shovel, plurality of spaced apart seed outlets adjacent the trailing edge of said shovel in .

transverse spaced and parallel relationship from one another, means operatively connecting said seed outlets with said feed conduit, a plurality of fertilizer outlets on the base of said shovel also in transverse spaced and parallel relationship with one another and with said seed outlets and alternating with said seed outlets, and means operatively connecting said fertilizer outlets with said fertilizer conduit.
Another advantage of the invention is to provide a device of the character herewithin described which en-ables seed and fertilizer to be placed in the correct re-lationship one to the other and at the same time thus re-quiring only one operation.
A still further advantage of the invention is to provide a device of the character herewithin described which is simple in construction, economical in manufacture and otherwise well suited to the purpose for which it is designed.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification pro-ceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which in-cludes a description of the best mode known to the appli-cant and of the preferred typical embodiment of the prin-ciples of the present invention, in which:

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference should first be made to Figures 9 and 10 in which reference character 11 illustrates schematical-ly, an assembly adapted to be connected behind a conven-tional air seeder device (not illustrated) by means of hitch 12 situated on the front of the longitudinally extending main beam 13, it being understood that the device travels in the direction of arrow 14.
Cross members 15 are secured to the main frame member 13 and implement shanks 16 extend downwardly there-from in a conventional manner.
A rear cross member 17 carries a packing assem-bly collectively designated 18 connected by means of pivots 19 with the packing assembly 18 including a plurality of packing wheels 20 mounted thereon and upon arms 21 with the pressure of the packer wheels being controlled by a hydraulic ram assembly 22 in a conventional manner.
Each shank 16 carries a shovel assembly collec-tively designated 23 on the lower end thereof and Figure 4 shows an example of the relationship of a plurality of shovel assemblies one with the other when assembled on the vehicle shanks.
In this embodiment, the shovel assemblies 23 are substantially triangular when viewed in plan and include a pair of wings 24 with a spanning web 25 extending there-~ -5--between as clearly illustrated in Figures 4 and 5. A pair of tubes are secured to the rear 25 of the shank 16 and ex-tend downwardly to the upper side of the shovel assembly 23, one of the tubes being a fertilizer feed tube 26 and the other being a seed feed tube 27. These are operative-ly connected in a conventional manner, to the air seeder and fertilizer device ~not illustrated) and convey seed and granular, gaseous, or liquid fertilizer to each shovel assembly as will hereinafter be described.
The seed feed tube 27 is connected at the lower end thereof to a manifold 28 within the shovel assembly from which a plurality of passageways or conduits 29 ex-tend to the trailing edge 30 of the shovel assembly. These conduits or passageways terminate in seed discharge open-ings 31 which are in transverse spaced relationship one with the other and are directed rearwardly and downwardly preferably at an angle from the horizontal of approximately 135. These deposit seed along dotted lines indicated by reference characters 32 and at a level determined by the depth of the shovel assemblies within the ground.
The fertilizer feed tube 26 also communicates with a manifold 33 within the shovel assembly from which a plurality of passageways or conduits 34 extend to fertil-izer shanks collectively designated 35 secured to and de-pending from the underside 36 of the shovel assembly.
These fertilizer shanks each include a leading edge 37 ~B
, 38~i~
which curves downwardly and rearwardly from the underside as clearly shown in Figure 7 and are provided with fertil-izer outlets 38 on the rear side thereof which terminate at a position indicated by reference character 39 situated spaced below the surface 36 of the shovel assembly and of course below the seed outlets 31.
Placement of these fertilizer shanks is such that `- ~3l733850 fertilizer is deposited in longitudinally extending strips indicated by solid lines 40 and the positioning of the shanks is such that fertilizer is deposited in longitudinal lines spaced and parallel from the seed lines 32 and alternating therewith and at a lower level than the seed lines. This difference in level is clearly shown in Figure 9.
If desired, wear bars 41 may be detachably secured to the front of the implement shanks 16 so that they can be replaced when worn.
In the present embodiment, the V-shaped shovel as-semblies are 90 assemblies but of course other types of shovel assemblies can readily be adapted for use with the present device.
The manifolds and the placement of the seed out-lets and fertilizer outlets allow for the accurate distribu-tion of seed and fertilizer with the seed being placed di-rectly in between two rows of fertilizer while the fertil-izer is placed a predetermined amount below the seed rows, for example, approximately 2 inches.
One of the advantages of using the same shovel as-sembly for placing seed and fertilizer is that the soil distrubance will be minimal and the design of the shovel and shank allow for excellent trash clearance while the trash is left on top of the soil.
This is an important development because recent research indicates that the placement of plant nutrients has ..
. .
. . . . .
~ .
, 11'7~BSC~
a very significant effect in improving crop yields.
As mentioned previously, plant nutrients normally are broadcast on the soil surface and then incorporated with tillage implements with the nutrients being mixed with the top soil to a depth of approximately 2 inches.
The present placement is extremely accurate and an advantage is that the plant roots will enter the zone rich in plant nutrients as the plant matures as indicated schema-tically in Figure 3. This is of special importance particu-larly where moisture is a limiting factor.
Air seeders currently are used mounted on heavy-duty cultivators in order to band the fertilizer in the fall or early spring and while this method of application shows improved results ~see Figure 2) there are disadvantages in-asmuch as the fertilizer and seed are placed by different operations so that consistency is not possible.
With the present device, the plant nutrients will always be placed in the same relative position to the seed and this consistent fertilizer placement assures that the root system of each plant has equal access to the nutrients thus assuring relatively eve,n crop development.
Furthermore, the device allows the placement of seed and plant nutrients in one operation thereby reducing the number of tillage operations which conserves vital moisture.
`` ~178851~
Finally, although the use of the device with seed and granuliar fertilizer is illustrated and described, the invention may be used with granular, liquid or gase~us fer-tiler with the seed outlets remaining at the rear edge of the shovel.
Since various modifications can be made in my in-vention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the ac-companying specification shall be interpreted as illustra-tive only and not in a limiting sense.

Proceeding therefore to describe the invention in detail, reference should first be made to Figures 9 and 10 in which reference character 11 illustrates schematical-ly, an assembly adapted to be connected behind a conven-tional air seeder device (not illustrated) by means of hitch 12 situated on the front of the longitudinally extending main beam 13, it being understood that the device travels in the direction of arrow 14.
