This application claims the benefit, under 35 U.S.C. 119(e), of U.S. provisional application No. 61/439,254, entitled “Furrow Tool for Seed Placement” and filed on Feb. 3, 2011. The entire contents of this application are hereby incorporated herein by reference in its entirety.
TECHNICAL FIELDThe technical field relates generally to agricultural planting equipment, and more specifically to seed placement tools.
BACKGROUNDMechanical seed planting devices are used to plant seeds accurately in furrows formed in a field. Planting devices are often pulled by a tractor and include multiple planting units. Each planting unit may hold seeds and may include a device to create a furrow in the ground as the tractor moves forward, and a device for closing the furrow around the seeds.
The seed placement in the furrow can affect the growth and characteristics of the plant. Often times as the seed drops from the planter into the furrow, via the seed tube, the seed may bounce. This bouncing may impact the direction and location of the seed distribution within the furrow. Additionally, as the seed may be traveling quickly through the seed tube, the seed may even bounce off of the ground at the bottom of the furrow, altering its location. The bouncing down the seed tube, or off the ground, may place the seeds on the side of the furrow or even outside the furrow. After the seed is placed within the furrow the furrow may be closed by the furrow closers. If the seeds are placed improperly (e.g., on the side of the furrow or outside the furrow completely), the seeds may not be adequately covered by soil.
Also, as seeds are deposited within the furrows even if they do not bounce out of place, they may still not be deposited at the correct depth. Often times there may be residual soil that may cause air pockets underneath the seed. Therefore, it may be desired to push or press the seed into place to better ensure that the planting depth may be accurate.
The plant depth and location affects the growth aspects of the plants. For example, improper seed placement may result in uneven plant emergence, poor strands, increase in weed population, uneven plant maturity, longer insect lift, higher susceptibility to chemical damage and lower yields.

Exemplary embodiments are illustrated in referenced figures of the drawings. It is intended that the embodiments and figures described and shown herein are to be considered illustrative rather than limiting. The use of the same reference numerals in different drawings indicates similar or identical items.
Although one or more of the embodiments of a seed planting tool may be described in detail with reference to a particular seed planting tool, the embodiments should not be interpreted or otherwise used as limiting the scope of the claims. In addition, one skilled in the art will understand that the following description has broad application. For example, while embodiments of the seed planting tool described herein may focus on seed location and depth, the concepts described herein equally apply to other planting and fertilization aspects. In addition, while the described embodiments may focus on a particular shaped furrow, the concepts set forth herein may equally apply to other furrow types and shapes, as well as to non-furrow planting. Accordingly, the discussion of any embodiment is meant only to be exemplary and is not intended to suggest that the scope of the claims is limited to these embodiments.
In some embodiments, a fertilizer tool is described that may be used with a variety of drills and planters.
The row unit 26 may include a seed hopper 14 that contains and dispenses the seeds 50, and a seed metering unit 30 may be positioned below the seed hopper 14. Additionally, the row unit 26 may include a fertilizer or watering tank (not shown) to provide nutrients to the seeds that are placed in the furrow 56. The seed metering unit 30 may receive seeds from the seed hopper 14. The seed metering unit 30 may facilitate depositing the correct number of seeds 50 in the furrow 56. Below the seed metering unit 30 may be a seed tube 42. The seed tube 42 may receive seeds from the seed hopper 14 (via the seed metering unit 30) and deposit the seeds 50 within the furrow 56. The row unit 26 may additionally include a furrow opening apparatus 16 that penetrates the ground to open the furrow 56. The furrow opening apparatus 16 may be placed beneath the seed hopper 14. The furrow opening apparatus 16 may include a divider at the leading edge of the row unit 26 and a furrow opener 34. The furrow opener 34 may be placed centrally underneath the seed hopper 14. The furrow opener 34 may be partially encompassed by a pair of gage wheels 20 and a pair of furrow closer wheels 24. The furrow close wheels 24 may trail behind the furrow opener 34 and gage wheels 20.
The furrow 56 may be formed by the furrow opener 34 as the row unit 26 is pulled by the planter. There are many different types of furrow openers. A double disk furrow opener 38 is illustrated in
The seed tube 42 may extend downward from the metering unit 30. The seed tube 42 may be positioned between the disk blades of the furrow opener 34. The seed tube 42 may include a bottom portion 40 that curves to generally define an acute angle between the ground and a longitudinal centerline of the seed tube 42. An opening 48 of the seed tube 42 may partially face the furrow tool 52. The seed tube 42 may be positioned over the furrow 56 to distribute seeds 50 received from the metering unit 30 into the furrow 56. As the metering unit 30 regulates the number of seeds distributed from the seed hopper 14, each seed 50 may be placed within the furrow 56 at a predetermined distance away from adjacent seeds 50. The seed tube 42 may have a substantially hollow body 44, and a bottom end of the seed tube 42 may be positioned to be directly over a centerline of the furrow 56. The bottom end 40 of the seed tube 42 may include the opening 48 through which the seeds 50 may exit the seed tube 42. The seed tube 50 may include a slightly arcuate shape along its length in a rearward direction. Such a shape may help to place the seeds 50 at the correct location within the furrow 56. As the seeds 50 travel through the seed tube 50, the seeds 50 may bounce as a result of the interaction with the walls of the seed tube 42 and the movement and velocity of the planter 10 over the ground.
The furrow tool 52 may be attached to the bottom portion 40 of the seed tube 42. The furrow tool 52 facilitates placing the seeds 50 in the proper location in the furrow 56 even though the seeds 50 may bounce within the seed tube 42. The furrow tool 52 may also press or compress the seeds 50 within the furrow 56 after they have been deposited therein. In these embodiments, the furrow tool 52 may help to position the seeds 50 at the correct depth and location within the furrow 56, which may result help in better plant growth and development rates. The furrow tool 52, in some embodiments, may include a deflector 62 or seed tube extension and a compressor 60. The furrow tool 52 may contact the seeds 50 both before and after the seeds 50 are deposited within the furrow 56. In these embodiments, the deflector 62 may contact the seeds 50 to facilitate placing the seeds 50 in a desired lateral location in the furrow 56, and the compressor 60 may then contact the seeds 50 to facilitate placing them at the correct depth within the furrow 56.
Turning to
Once the seeds 50 are placed into the furrow 56, the compressor 60 passes over the seeds 50. The compressor 60 helps to position the seeds 50 at the correct depth within the furrow 56. In some embodiments, the compressor 60 may press the seeds 50 into the furrow bottom. In some embodiments, the compressor 60 may also compress soil/earth in the furrow to eliminate any air pockets. By eliminating the air pockets and compressing the soil, the seeds 50 can settle into the desired depth within the furrow 56. Furthermore, by compressing the seeds 50 into the furrow 56, the seeds 50 are more likely to be planted at a uniform planting depth. The compressor 60 may be configured to provide varying pressure to the seeds 50. For example, altering the material, size or attachment location the compressor 60 may result in the application of more or less force to the seeds 50, thus allowing the furrow tool 52 to be used with a variety of seeds 50.
The compressor 60, the deflector 62, and the attachment bracket 74 may be formed using the same or similar same materials, or they may be formed using different materials. In some embodiments, the compressor 60 and the deflector 62 may be made of plastic, metal, wood, or the like.
The deflector 62 may be attached or connected to a bottom portion of the compressor 60, and the compressor 60 may extend past the end portion of the deflector 62. In these embodiments, when a seed 50 is released from the seed tube 42 and the seed 50 bounces, it may hit the deflector 62. After the seed 50 rests within the furrow 56, the compressor 60 may be dragged over the seed 50 to compress the seed 50 into the furrow 56. In these embodiments, the deflector 62 may initially contact the seeds 50 as they are dropped from the seed tube 42, and then the compressor 60 may contact the seeds 50 after they are deposited in the furrow 56. In some embodiments, the compressor 60 may have a longer total length than the deflector 62. This configuration may allow the compressor 60 to contact the seeds 50 after the deflector 62. Additionally, the deflector 62 may be configured so as to not contact the seeds 50 once they are deposited within the furrow 56. In these embodiments, the deflector 62 may not touch the furrow 56. This configuration may help to eliminate unnecessary pressure on the seeds 50, which may damage them.
The compressor 60 may have a lower total height where it attaches to the deflector 62, and may increase in height after the deflector 62. In these embodiments, the distal end of the compressor 60 may be significantly larger than the front end. The bottom portion 64 of the compressor 62 may be configured to press the seeds 50 into the furrow 56. As the bottom portion 64 of the compressor is dragged over the seeds 50 as the planter 10 pulls the furrow tool 52, the weight of the compressor 60 presses the seeds 50 into the furrow 56.
The compressor 60 also may include an outer protrusion 63 extending from the back or distal end of the compressor body 60. The outer protrusion 63 may be used to hold a fertilizer tube. For example, as shown in
The compressor 60 may include a compressor body. The compressor body may be generally oval shaped with a flat top face 61 and angled sides. The compressor body may expand in height from the front to the back end of the compressor body. In some embodiments, the compressor 60 may also include a step 66 at the transition point from the connection area to the back area of the compressor 60. The step 66 may be included to reduce the weight and material required to create the compressor 60. For example, the compressor 60 may be constructed to have a large height, which increases the weight of the compressor. This increased weight allows for a greater force to be applied to the seeds 50 by the compressor. However, the large height and/or weight may only be required for the portion of the compressor 60 that contacts the seeds 50. Therefore, the step 66 may reduce the amount of material used for the entire compressor 60, while still providing sufficient height and/or weight to press the seeds 50 into the furrow 56. The step 66 may also be used to allow the furrow tool 52 to be easily connected to the seed tube 42 and to maintain a desired spacing between the row unit 26 (e.g., the discs, the wheels, etc.) and the furrow tool 52.
The compressor 60 may also include various tabs, hooks, or protrusions 68, 70, 72 located on an upper portion of the compressor body. The protrusions 68, 70, 72 may be used to secure one or more components of a fertilizer tube assembly, such as a fertilizer tube, to the top face 61 of the compressor 60. With reference to
The compressor 60 may be connected to an attachment bracket 74 at a neck portion 86 of the compressor body. The neck portion 86 may be slightly bent or rounded towards the ground. In these embodiments, the compressor 60 may be angled generally downwards towards the ground to press the seeds 50 downward in the furrow 56. The angle of the compressor 60 may be increased or decreased to alter the force exerted onto the seeds 50 by the compressor 60.
In some embodiments, the bottom portion 64 of the compressor 60 may be shaped to generally conform to the shape of the furrow 56. For instance, if the furrow 56 has a v-shape, the bottom portion 64 may be shaped to have a relatively small width. The walls from the bottom portion 64 to the top of the compressor 62 may be angled to be substantially the same angle as the walls of the furrow 56. In these embodiments, the compressor 60 may be better able to track the shape of the furrow 56, and thus most efficiently press the seeds 50 into the furrow 56. Additionally, the shape and size of the compressor 60 may be adjusted to accommodate the types of crops being grown and the soil conditions. For instance, some seeds 50 may require significant pressure, whereas other seeds 50 may be easily damaged and thus lighter pressing is required. In these embodiments, the shape of compressor 60 may be changed as well as the material. For example, a lighter material may be used for easily damaged seeds, whereas a heavier material may be used for seeds that can withstand more force. Also, the shape of the compressor 60 may be altered such that the bottom portion 64 may not fit/reach to the bottom of the furrow 56, thus the amount of force applied by compressor 60 to the seeds 50 may be reduced.
The deflector 62 may be secured to the compressor 60 and may extend beyond the width of the compressor 60. In these embodiments, the deflector 62 may be wider than the compressor 60, and the compressor 60 may extend past the deflector 62 and be longer than the deflector 62. In these embodiments, the deflector 62 can direct seeds 50 bouncing in a variety of directions from the seed tube 42. The deflector 62 may curve downwards at a bend point 88. In these embodiments, the deflector 62 may be generally rounded and follow the shape of the compressor 60. The deflector 62 may also be configured to receive fertilizer tubes as shown in
The fertilizer tubes may be attached by fasteners connected at apertures 92 located on a front or top face of the deflector 62. The apertures 92 may be raised above the body of the deflector 62 and be spaced apart from one another. In other embodiments, the apertures 92 may be omitted (for instance if no fertilizing is desired), or the apertures 92 may be located in other areas of the deflector 62. The deflector 62 may be shaped to generally follow the width of the furrow 56 and therefore be better able to deflect the seeds 50 regardless of how the seeds 50 bounce. In some embodiments, the deflector 62 may have rounded sides and a flat front face. However, in other embodiments the deflector 62 may be shaped to accommodate other planter and/or types of furrows 56. For example, if the furrow 56 is shaped wider or formed in a shape other than a V, the deflector 62 may be shaped to mimic that additional width or different shape to provide bounce coverage for the seeds 50.
The attachment bracket 74 may be attached to the compressor 60 and the deflector 62 via the neck portion 86 of the compressor. The neck portion 86 may be integral with the attachment bracket 74, or may be attached via glue, welding, or the like. The attachment bracket 74 secures the furrow tool 52 to the seed tube 42 or other location on the row unit 26. In some embodiments, the furrow tool 52 may be attached to the seed tube 42 via fasteners. The fasteners (not shown) may be attached via fastener apertures 76, 78, 80, 82. In some embodiments, the fasteners may wrap around the seed tube 42 (e.g. wire, string, plastic connectors, or the like), and in other embodiments, the fasteners may be screws, nails, or the like that attach to a bracket or at another attachment area on the seed tube 42.
The attachment bracket 74 may also include projections 84. The projections 84 may assist in attaching the bracket but are not required. The attachment bracket 74 illustrates one embodiment for attaching the furrow tool 52 to the row unit 26. In other embodiments, the furrow tool 52 may be attached in a variety of ways. In some embodiments, the furrow tool 52 may be integrated with the seed tube 42. However, the attachment bracket 74 allows the furrow tool 52 to be used with a variety of planters 10, including different row units 26 and seed tubes 42 since the furrow tool 52 may be attached to a variety of already existing planting devices. The attachment bracket 74 also allows the height of the furrow tool 52 to be readily adjusted so that the compression pressure applied by the compressor 60 and the height of the compressor 60 or the deflector 62 above the bottom of the furrow 56 may be adjusted.
