Description
FURROW OPENER TIP FOR PLACEMENT OF FERTILIZER ADJACENT TO
SEED
This invention is in the field of agricultural seeders, and in particular furrow openers for use with such seeders.
BACKGROUND
Seeders are used in agriculture to seed and fertilize fields, and also often to apply lo pesticides, herbicides, and the like. Such seeders generally comprise a plurality of shanks extending down from an implement frame, and a furrow opener attached to the bottom of each shank. Seed and fertilizer are conveyed from a supply tank through a delivery tube to a location where same can fall into the furrow created by the furrow opener. Seed and fertilizer are sometimes mixed and conveyed through a single tube, or a separate tube can be supplied for each of the seed and fertilizer.
Fertilizer can be either in liquid or granular form. Granular fertilizer can be mixed with the seed or conveyed in a separate tube by an air stream or gravity. Liquid fertilizer is pumped through a tube separate from that conveying the seed to a location where same can fall into a furrow. Double shooting furrow openers direct seed and fertilizer to somewhat separate areas of the furrow. Where higher rates of fertilizer application are used, it is desirable to provide some distance between the location of the seed and the fertilizer in the furrow to avoid damage to the seed that can be caused by high concentrations of fertilizer.
United States Patent Number 4,565,141 to Kopecky for example discloses such a double shooting furrow opener, where the furrow opener is configured such that fertilizer is delivered to the bottom of the furrow a.nd seed is delivered to an upper portion of the furrow.
United States Patent Number 6,457,426 to Cruson also discloses a double shoot furrow opener that deposits seed at the bottom of the furrow and seed is delivered to upper portions of the furrow on each side of the fertilizer location. The Cruson opener also shows a replaceable furrow opener tip, such as is conunonly known in the art.
The tip is generally made from a hardened material and the furrow opener is configured such that the tip provides the furrow opening element that takes the majority of the wear caused by contact with the soil. When the tip is worn out, it can be readily removed and replaced by removing a roll pin extending laterally through the tip and through a lug on the bottom end of the furrow opener body that extends into a recess in the back of the tip.
Where the liquid form of fertilizer is used, it is known to arrange a rigid pipe attached to the furrow opener such that the bottom discharge end of the pipe is directed to deposit fertilizer into the furrow. The furrow opener used may be of the type used to make a t5 conventional single furrow, such that the liquid drops into the furrow with or very close to the seed. The fertilizer pipe can be oriented to drop the fertilizer directly behind the furrow forming portion of the furrow opener such that the fertilizer is at the very bottom of the furrow. The seed tube is located somewhat rearward in order to allow at least some soil to fall back onto the fertilizer before the seed falls into the furrow, thereby providing some separation.
The fertilizer pipe discharge may also be oriented behind the furrow opening element and directed to a side of the furrow. Tips are known, such as the wart knife made by Dutch Industries Ltd. of Pilot Butte, Saskatchewan, Canada, that include a protrusion extending from one side of the knife tip such that a groove is created in one side of the furrow. The discharge of a liquid fertilizer pipe is oriented to deposit liquid fertilizer into the groove to provide separation between the fertilizer in the groove and the seed in the main furrow.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a furrow opener for agricultural seeders that overcomes problems in the prior art.
In a first embodiment the invention provides a furrow opener tip adapted for attachment at a rear portion thereof to a furrow opener of an agricultural seeder for travel in a forward operating travel direction. The tip defines a channel with an input opening at a first face of the tip and at least one output opening at a second face of the tip, such that liquid fertilizer entering the input opening flows through the channel and out the at least one output opening.
In a second embodiment the invention provides a furrow opener apparatus adapted for attachment to an agricultural seeder for travel in a forward operating travel direction.
The apparatus comprises a furrow opener body adapted for attachment to a seeder shank at an upper portion thereof. A tip is removably attached at a rear portion thereof to a lower forward portion of the furrow opener body, the tip defining a channel with an input opening at a first rear face of the tip and at least one output opening at a second face of the tip. A substantially rigid liquid fertilizer pipe is fixed to the furrow opener body and has an input end adapted for attachment to a fertilizer tube and a discharge end extending into the input end of the channel such that liquid fertilizer can flow through the liquid fertilizer pipe and through the channel and out the at least one output opening.
The tip of the invention thus provides a tip that can conduct liquid fertilizer through a channel defined by the tip to a desired location, such as to provide separation of seed and fertilizer to prevent crop damage. Conveniently, the furrow opener can include a substantially rigid liquid fertilizer pipe attached thereto such that when the tip is engaged on the furrow opener, the discharge end of the pipe will enter the input opening of the channel. Output openings can be provided on each side of the tip. By dividing the liquid fertilizer into two streams, the concentration of liquid fertilizer inany particular portion of the soil will be reduced, reducing the risk that high fertilizer concentrations will damage the seed. The output openings can be oriented to face somewhat rearward to reduce the risk that soil flowing past the openings as the tip moves through the soil will enter the output openings and plug them.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
Figs. 1 and 2 illustrate a furrow opener apparatus 1 adapted for attachment to an agricultural seeder for travel in a forward operating travel direction T. The apparatus comprises a furrow opener body 3 adapted for attachment to a seeder shank at an upper portion thereof by bolts through holes 5, or by a quick attach mechanism or like mechanism as is known in the art. The illustrated furrow opener body includes a bracket 6 adapted to receive a seed tube that can be clamped to the bracket 6. The bracket 6 to holds an attached seed tube in an orientation such that seed flowing from the seed tube falls into the furrow created by the furrow opener apparatus 1. In other configurations the seed tube may be attached in a suitable location by other mechanisms such as are known in the art.
A tip 7 is shown in Figs. 3 - 5, and is removably attached at a rear portion thereof to a lower forward portion of the furrow opener body 3. In the illustrated embodiment, the tip 7 is removably attached to the furrow opener by a lug 8 extending from the furrow opener 3 into a recess 9 on the rear portion of the tip 7, and by a pin 11 extending laterally through corresponding holes 13 in the tip 7 and lug 8 in a manner such as is known in the art for attaching such replaceable tips to a furrow opener.
The tip 7 defines a channel 15 wit.h an input opening 17 at the rear face of the tip 7 and an output opening 19 on a side face of the tip 7. As best seen in the bottom view of the tip 7 illustrated in Fig. 5, the channel 15 in the illustrated embodiment includes a right output opening 19R on a right side face of the tip 7 and a left output opening 19L on a left side face of the tip 7.
A substantially rigid liquid fertilizer pipe 21 is fixed to the furrow opener body 3 and has an input end 23 adapted for attachment to a fertilizer tube to receive liquid fertilizer, and a discharge end 25 extending into the input end 17 of the channel 15 such that liquid fertilizer flowing from the fertilizer tube flows through the liquid fertilizer pipe 21 and through the channel 15 and out the output openings 19R, 19L.
As can be seen in Figs. 1 and 2, when the tip 7 is moved rearward to engage the lug 8 in the recess 9, the discharge end 23 of the liquid fertilizer pipe 21 attached to the furrow opener body 3 enters the input opening 17 of the channel 15. When the tip 7 is attached to the furrow opener body 3 in an operating position, the input opening 17 is somewhat above the output openings 19, such that liquid fertilizer flows through the channel 15 by gravity.
In the embodiment of the tip 7 illustrated in Figs. 3 - 5, the right and left side faces 27 of the tip 7 are oriented at an angle N to the operating travel direction T such that the side faces 27 slope inward toward a center of the tip 7 from front edges 28 of the side faces to rear edges 29 thereof. Thus the output openings 19 are facing rearward to some degree.
As can be seen from the drawings, the front edges 28 of the side faces 27 are located substantially at the widest portion of the tip 7 such that as the tip 7 travels through the soil, the soil flows outward and upward from the front end of the tip 7 along both sides of the tip 7 to the front edges 28 of the side faces 27 and then the side faces slope inward toward the rear end of the tip 7. The rearward orientation of the output openings 19 reduces the risk that soil will plug the output openings 19.
It is contemplated that the angle N could be very small, in the order of about three degrees, or quite large, up to about sixty degrees. It is contemplated however that in a typical tip the angle N will be about four to ten degrees. In the embodiments illustrated, the angle N is shown quite large for illustration purposes.
In the embodiment of the tip 7 illustrated in Figs. 3 - 5, the input opening 17 of the channel 15 is located below the recess 9, and the channel 15 extends under the recess 9 and divides to connect to the right and left output openings 19R, 19L.
Fig. 6 illustrates an alternate embodiment of the tip 107 wherein the input opening 117 of the channel 115 is located beside the recess 109 and the channel 115 extends beside the recess 115 to the output opening 119 on the side face 127. Such an alternate tip 107 thus delivers liquid fertilizer to only one side of the furrow created by the furrow opener, which will be satisfactory in many situations.
While the illustrated embodiments show the output openings located on side faces 27, 127 of the tips 7, 107 it is contemplated that in some cases it could be desirable to locate the output openings of the channel on the bottom face.
The foregoing is considered as illustrative only of the principles of the invention.
Further, since numerous changes and modifications will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
Figs. 1 and 2 illustrate a furrow opener apparatus 1 adapted for attachment to an agricultural seeder for travel in a forward operating travel direction T. The apparatus comprises a furrow opener body 3 adapted for attachment to a seeder shank at an upper portion thereof by bolts through holes 5, or by a quick attach mechanism or like mechanism as is known in the art. The illustrated furrow opener body includes a bracket 6 adapted to receive a seed tube that can be clamped to the bracket 6. The bracket 6 to holds an attached seed tube in an orientation such that seed flowing from the seed tube falls into the furrow created by the furrow opener apparatus 1. In other configurations the seed tube may be attached in a suitable location by other mechanisms such as are known in the art.
A tip 7 is shown in Figs. 3 - 5, and is removably attached at a rear portion thereof to a lower forward portion of the furrow opener body 3. In the illustrated embodiment, the tip 7 is removably attached to the furrow opener by a lug 8 extending from the furrow opener 3 into a recess 9 on the rear portion of the tip 7, and by a pin 11 extending laterally through corresponding holes 13 in the tip 7 and lug 8 in a manner such as is known in the art for attaching such replaceable tips to a furrow opener.
The tip 7 defines a channel 15 wit.h an input opening 17 at the rear face of the tip 7 and an output opening 19 on a side face of the tip 7. As best seen in the bottom view of the tip 7 illustrated in Fig. 5, the channel 15 in the illustrated embodiment includes a right output opening 19R on a right side face of the tip 7 and a left output opening 19L on a left side face of the tip 7.
A substantially rigid liquid fertilizer pipe 21 is fixed to the furrow opener body 3 and has an input end 23 adapted for attachment to a fertilizer tube to receive liquid fertilizer, and a discharge end 25 extending into the input end 17 of the channel 15 such that liquid fertilizer flowing from the fertilizer tube flows through the liquid fertilizer pipe 21 and through the channel 15 and out the output openings 19R, 19L.
As can be seen in Figs. 1 and 2, when the tip 7 is moved rearward to engage the lug 8 in the recess 9, the discharge end 23 of the liquid fertilizer pipe 21 attached to the furrow opener body 3 enters the input opening 17 of the channel 15. When the tip 7 is attached to the furrow opener body 3 in an operating position, the input opening 17 is somewhat above the output openings 19, such that liquid fertilizer flows through the channel 15 by gravity.
In the embodiment of the tip 7 illustrated in Figs. 3 - 5, the right and left side faces 27 of the tip 7 are oriented at an angle N to the operating travel direction T such that the side faces 27 slope inward toward a center of the tip 7 from front edges 28 of the side faces to rear edges 29 thereof. Thus the output openings 19 are facing rearward to some degree.
As can be seen from the drawings, the front edges 28 of the side faces 27 are located substantially at the widest portion of the tip 7 such that as the tip 7 travels through the soil, the soil flows outward and upward from the front end of the tip 7 along both sides of the tip 7 to the front edges 28 of the side faces 27 and then the side faces slope inward toward the rear end of the tip 7. The rearward orientation of the output openings 19 reduces the risk that soil will plug the output openings 19.
It is contemplated that the angle N could be very small, in the order of about three degrees, or quite large, up to about sixty degrees. It is contemplated however that in a typical tip the angle N will be about four to ten degrees. In the embodiments illustrated, the angle N is shown quite large for illustration purposes.
In the embodiment of the tip 7 illustrated in Figs. 3 - 5, the input opening 17 of the channel 15 is located below the recess 9, and the channel 15 extends under the recess 9 and divides to connect to the right and left output openings 19R, 19L.
Fig. 6 illustrates an alternate embodiment of the tip 107 wherein the input opening 117 of the channel 115 is located beside the recess 109 and the channel 115 extends beside the recess 115 to the output opening 119 on the side face 127. Such an alternate tip 107 thus delivers liquid fertilizer to only one side of the furrow created by the furrow opener, which will be satisfactory in many situations.
While the illustrated embodiments show the output openings located on side faces 27, 127 of the tips 7, 107 it is contemplated that in some cases it could be desirable to locate the output openings of the channel on the bottom face.
The foregoing is considered as illustrative only of the principles of the invention.
Further, since numerous changes and modifications will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention.
