Abstract
A furrowing tip selectively mounts on an opener body to produce a paired row furrow opener. The furrowing tip includes a knife portion and a pair of wing portions formed integrally in a single bodied replaceable tip. A deflector is provided, which may be formed on the tip body and which co-operates with the wing portions to produce a pair of parallel rows offset laterally in opposing directions from a centred row deposited behind the knife portion. When the knife portion and wing portions become worn, only the tip body requires replacement.
Description
PAIRED ROW FURROW OPENER
FIELD OF THE INVENTION
The present invention relates to a paired row furrow opener, and more particularly relates to a replaceable tip for replacing the wearing components in a paired row furrow opener.
BACKGROUND
The use of paired row for row openers are known when it is desirable to place two rows of seed and a row of fertiliser parallel to one another trailing a single furrowing element. A typical arrangement of a paired row opener includes a knife to produce a deep narrow furrow and separate wings spaced in the direction of travel and laterally outward in relation to the knife for widening the furrow to position a pair of seeded rows along opposing sides of the furrow. Examples of furrowing elements which may be operate as a paired row furrow opener include United States patents 6,332,412 to Swab et al; 4,674,419 to Kopecky; 4,726,304 to Dreyer et al;
4,770,112 to Neumeyer; 5,161,472 to Handy; 5,351,635 to Hulicsko and 6,357,368 to Swab et al. In each instance wings are provided which are positioned to be spaced in the working direction either forwardly or rearwardly of the knife such that the wings and the knife are required to be formed separately. In many instances a large furrow is required for proper placement of the fertiliser and seed resulting in considerabte draft forces being required for pulling through the ground. Furthermore both of the wings and the knife are known to wear in use requiring replacement of both components periodically separately from one another.
The use of a single bodied opener which can be supported on an implement shank and includes both fertiliser and seed passages therethrough is also known, however in such an arrangement when the wings and knife are known to wear, replacement of the entire opener body is required in any known example.

DETAILED DESCRIPTION
Referring to the accompanying drawings, there is illustrated a furrowing tip generally indicated by reference numeral 10. The tip 10 is particularly suited for being supported on a furrowing opener 12 to produce a paired row when seeding.
The opener generally includes an opener body having a shank mount 14 formed integrally thereon with apertures to permit fastening to the shank of an implement using suitable fasteners. A first particulate material tube 16 and a second particulate material tube 18 are supported on the opener body for connection to seed and fertiliser tubes of an implement respectively.
As shown in Figures 1 through 7, the opener body generally comprises a channel enclosed at the front 20 and along sides 22 to permit the fasteners to mount to the shank to be enclosed within an interior of the channel. The channel is open to the rear to receive the first and second particulate material tubes supported therebetween. At a bottom end of the leading side of the opener body, a forward and downward extending projection 24 is provided for supporting the furrowing tip thereon. The projection 24 is centred laterally with respect to the shank mount. A
fastener aperture extends through the projection perpendicularly to the forward working direction for fastening the furrowing tip thereon.
The furrowing tip 10 is a cast member having a socket 30 formed in a rear side thereof which is suitably shaped to mate with the projection 24 of the opener body. The body of the tip 10 includes a transverse aperture formed therein which also lies perpendicularly to the forward working direction so as to be aligned with the fastener aperture of the projection 24 on the opener body to receive a mating fastener, for example a locking pin or the like therethrough.
The tip body includes a narrow main portion 32 which tapers forwardly and downwardly into the working direction to define a knife portion 34 at the leading edge which tapers to an apex formed at a bottom end thereof which includes wear resistant material 36 secured thereon by welding and the like. The bottom apex of the knife portion 34 is pointed and aligned with the socket 34 on the rear side of the tip body so that the knife portion is aligned with the shank mount.
The tip body further includes a pair of wing portions 38 which extend -aterally outwardly at a rearward incline from opposing sides of the ICnife portion 34.
-S' The wing portions 38 are formed integrally with the knife portion and the remaining structure of the tip body. A leading edge 40 of each wing portion projects genereity horizontally in use and similarly includes wear resistant material formed thereon. An upper surface of each wing portion slopes upwardly from the leading edge 40.
The leading edge lies at an inclination of substantially less than 45 degrees from the forward working direGtion for minimising drag when pulling through the ground.
As shown in the illustrated embodiment Figure 4, the leading edge of each wing portion lies at an inclination of approximately 25 degrees from the forward working direction of the opener. 0 An inner bottom surface 42 of each wing portion is inclined similarly to the upper surfaces so as to project at a downward and laterally outward incline to a respective outer free end of the wing portion to define an open cavity 44 under each wing pordon. Each wing poition includes a rear portion 46 projecting generally rearwardly from the outer ends of the leading edge 40 to extend the area of the cavity undemeath the wing portions. The cavity 44 defined under each wing portion is open to the rear and to the bottom while being joined by an inner chamber area 48 below the connection of the projec#ion 24 of the opener body with the socket 30 of the tip body. As shown in Figure 7, each cavity 44 is open to a rear and bottom between the deflector 50 and the outer free end of the wing portion.
A deflector 50 is mounted between the wings near in height to the leading edge thereof to project rearwardly from the main portion of the tip body while being formed integrally therewith to terminate at a rear end below the first particulate material tube only. The second pardculate material tube, positioned rearwardly of the first particulate material tube, remains unobstructed by the tip body. The deflector 50 encloses a bottom of the inner chamber 48 defined between the open cavities under each respective wing portion while permitting the inner chamber to remain open in communication with the cavities through opposing respective sides thereof. As shown in Figure 5, the deflector 50 is spaced below the first and second particulate material tubes 16 and 18, A central ridge 52 is provided along the deflector which extends centrally and parallel to the working direction to define a pair of upwardly facing deflector surfaces 54 on opposing sides of the ridge 52 which each span downwardly and laterally outwardly to respective free ends which terminate at the open cavities 44 beneath the wing portions 38 respectively.
In this arrangement particulate material deflected down through the first particulate materiai tube and chamber 48 impacts the deflector surfaces 54 on opposing sides of the central ridge of the deflector to be separated and split evenly into opposing streams which are deflected into the open cavities 44. The cavities 44, being bound along a top side by respective inner bottom surfaces 42 of the wing portions 38, thereby deposit a pair of seeded rows behind the wing portions 38 respectively.
A rear flange 58 is provided on the deflector to extend generally upwardly from the rear end thereof to ensure that substantially all particulate material from the first particulate material tube is deflected to either one of the laterally spaced rows behind the wing portions respectfully so as not to mix with a second particulate materiai, for example fertiliser, being deposited through the second tube which is unobstructed and positioned rearwardly of the deflector permitting a fertiiiser row to be formed between the opposed laterally spaced seeded rows of the wing portions 38.
Accordingly once the tip body is atkached to the opener body on an implement shank, fertiliser can be fed through the second tube to be deposited in the deepest part of the furrow directly behind the knife portion of the tip body.
The knife projects downwardly below the wing portions to produce the deepest part of the furrow. Seed deposited in the first tube is split on the divider ridge of the deflector to be deflected into a pair of rows deposited through the open bottom side of the cavities 44 below the wing portions 38 respectfuliy.
After extended use the only components which suffer from any substantial wearing are the knife portion and the wing portions which can be readily replaced by removing a single fastener through the co-operating apertures of the socket and projection of the tip body and opener body respectively. A
replacement tip body can then be mounted on the projection and a fastener again inserted through the co-operating apertures for proper securement on the opener bodies.
As illustrated in the accompanying figures, a single configuration of the tip body may be provided which can mount on various configurations of opener bodies. As indicated by like reference numerals in Figures 10 and 11, the openers include various common elements.
In other embodiments one side of the deflector 50 may be blocked to produce only a single offset row of particulate material delivered through the first tube in relation to material delivered through the second tube. The furrowing tip 10 may also differ in its appiication by dispensing only seed, or only fertiliser or various combinations thereof through the first and second tubes as desired to produce a desired combination of offset rows or paired rows of material being dispensed.
In yet further embodiments, the deflector 50 may be formed separately from the tip body and attached to the opener body directly. In this arrangement, the deflector 50 would remain possitioned below the first tube while the second tube remains unobstructed. The use of the rear flange on the deflector in either instance, or the use of a functional equivalent, ensures that all of the first material is deflected to either one of the lateral dimctions behind respective ones of the wing portions so that seed can be deposited ofFset from fertiliser in a double shoot seeder application while tsking advantage of the wearing surfaces of both the knife and wing porttons being formed on a single replaceable tip body.
While one embodiment of the present invenfion has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.

The opener generally includes an opener body having a shank mount 14 formed integrally thereon with apertures to permit fastening to the shank of an implement using suitable fasteners. A first particulate material tube 16 and a second particulate material tube 18 are supported on the opener body for connection to seed and fertiliser tubes of an implement respectively.
As shown in Figures 1 through 7, the opener body generally comprises a channel enclosed at the front 20 and along sides 22 to permit the fasteners to mount to the shank to be enclosed within an interior of the channel. The channel is open to the rear to receive the first and second particulate material tubes supported therebetween. At a bottom end of the leading side of the opener body, a forward and downward extending projection 24 is provided for supporting the furrowing tip thereon. The projection 24 is centred laterally with respect to the shank mount. A
fastener aperture extends through the projection perpendicularly to the forward working direction for fastening the furrowing tip thereon.
The furrowing tip 10 is a cast member having a socket 30 formed in a rear side thereof which is suitably shaped to mate with the projection 24 of the opener body. The body of the tip 10 includes a transverse aperture formed therein which also lies perpendicularly to the forward working direction so as to be aligned with the fastener aperture of the projection 24 on the opener body to receive a mating fastener, for example a locking pin or the like therethrough.
The tip body includes a narrow main portion 32 which tapers forwardly and downwardly into the working direction to define a knife portion 34 at the leading edge which tapers to an apex formed at a bottom end thereof which includes wear resistant material 36 secured thereon by welding and the like. The bottom apex of the knife portion 34 is pointed and aligned with the socket 34 on the rear side of the tip body so that the knife portion is aligned with the shank mount.
The tip body further includes a pair of wing portions 38 which extend -aterally outwardly at a rearward incline from opposing sides of the ICnife portion 34.
-S' The wing portions 38 are formed integrally with the knife portion and the remaining structure of the tip body. A leading edge 40 of each wing portion projects genereity horizontally in use and similarly includes wear resistant material formed thereon. An upper surface of each wing portion slopes upwardly from the leading edge 40.
The leading edge lies at an inclination of substantially less than 45 degrees from the forward working direGtion for minimising drag when pulling through the ground.
As shown in the illustrated embodiment Figure 4, the leading edge of each wing portion lies at an inclination of approximately 25 degrees from the forward working direction of the opener. 0 An inner bottom surface 42 of each wing portion is inclined similarly to the upper surfaces so as to project at a downward and laterally outward incline to a respective outer free end of the wing portion to define an open cavity 44 under each wing pordon. Each wing poition includes a rear portion 46 projecting generally rearwardly from the outer ends of the leading edge 40 to extend the area of the cavity undemeath the wing portions. The cavity 44 defined under each wing portion is open to the rear and to the bottom while being joined by an inner chamber area 48 below the connection of the projec#ion 24 of the opener body with the socket 30 of the tip body. As shown in Figure 7, each cavity 44 is open to a rear and bottom between the deflector 50 and the outer free end of the wing portion.
A deflector 50 is mounted between the wings near in height to the leading edge thereof to project rearwardly from the main portion of the tip body while being formed integrally therewith to terminate at a rear end below the first particulate material tube only. The second pardculate material tube, positioned rearwardly of the first particulate material tube, remains unobstructed by the tip body. The deflector 50 encloses a bottom of the inner chamber 48 defined between the open cavities under each respective wing portion while permitting the inner chamber to remain open in communication with the cavities through opposing respective sides thereof. As shown in Figure 5, the deflector 50 is spaced below the first and second particulate material tubes 16 and 18, A central ridge 52 is provided along the deflector which extends centrally and parallel to the working direction to define a pair of upwardly facing deflector surfaces 54 on opposing sides of the ridge 52 which each span downwardly and laterally outwardly to respective free ends which terminate at the open cavities 44 beneath the wing portions 38 respectively.

In other embodiments one side of the deflector 50 may be blocked to produce only a single offset row of particulate material delivered through the first tube in relation to material delivered through the second tube. The furrowing tip 10 may also differ in its appiication by dispensing only seed, or only fertiliser or various combinations thereof through the first and second tubes as desired to produce a desired combination of offset rows or paired rows of material being dispensed.
In yet further embodiments, the deflector 50 may be formed separately from the tip body and attached to the opener body directly. In this arrangement, the deflector 50 would remain possitioned below the first tube while the second tube remains unobstructed. The use of the rear flange on the deflector in either instance, or the use of a functional equivalent, ensures that all of the first material is deflected to either one of the lateral dimctions behind respective ones of the wing portions so that seed can be deposited ofFset from fertiliser in a double shoot seeder application while tsking advantage of the wearing surfaces of both the knife and wing porttons being formed on a single replaceable tip body.
While one embodiment of the present invenfion has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
