Abstract

One or more techniques and/or systems are disclosed for mounting a dual fertilizer opener to a planting implement, the dual fertilizer opener including a frame support having a first end and a second end, the first end mounted to a frame of a planting implement and positioned such that the dual fertilizer opener is implemented before a seed opener, and the second end coupled to a first opener assembly and a second opener assembly. Each opener assembly is configured to individually pivot about the second end of the frame support, a downforce being exerted on each by a spring. Each opener assembly is further configured to be adjustable such that each trench opened in the soil may be at a desired depth and distance from a seed location, resulting in greater root development that increases nutrient taking and yield

First claim

What is claimed is:

1 . A dual fertilizer opener movable in a working direction for opening a trench in soil, comprising:
a frame support having a first end and a second end, the first end coupled to a frame of a planting implement; and a first opener assembly and a second opener assembly, each of the first and second opener assemblies comprising:
a support arm having a first end selectably, pivotably engaged with the frame support and a second end engaged with an axle;
a blade selectably coupled to the axle and configured to rotate about the axle;
a wheel bracket comprising a plurality of apertures and selectably coupled to the axle at a first aperture of the plurality of apertures;
a wheel selectably coupled to the wheel bracket at a second aperture of the plurality of apertures and configured to rotate about an axis of the second aperture; and
a spring selectably, pivotably coupled to the frame support and configured to provide a downforce to the respective opener assemblies, resulting in additional downforce application to the opener assemblies in conjunction with a downforce applied by the planting implement.

2 . The fertilizer opener according to claim 1 , wherein the first opener assembly is configured to pivot independently from the second opener assembly.

3 . The fertilizer opener according to claim 1 , wherein the first opener assembly and second opener assembly are configured to pivot between a first position and a second position, wherein the first position comprises a lower position than the first position.

4 . The fertilizer opener according to claim 1 , wherein the first opener assembly and second opener assembly are configured to be convertible between at least a first lateral position from the frame support and a second lateral position from the frame support along an axis orthogonal to the working direction, the second lateral position being further from the frame support than the first lateral position.

5 . The fertilizer opener according to claim 4 , further comprising one or more spacers configured to effectuate the conversion of the first opener assembly and second opener assembly from the first lateral position to the second lateral position.

6 . The fertilizer opener according to claim 5 , wherein the first lateral position disposes the blade of the respective first and second opener assemblies at two inches from a center seed placement, and the second lateral position disposes the blade of the respective first and second opener assemblies at three inches from a center seed placement.

7 . The fertilizer opener according to claim 1 , wherein the wheels of respective opener assemblies are configured to be convertible between a first wheel position in relation to its corresponding blade and a second wheel position in relation to its corresponding blade, wherein in the first wheel position a distance between a bottom edge of the blade and a bottom edge of the wheel comprises a first distance, and in the second wheel position a distance between the bottom edge of the blade and the bottom edge of the wheel comprises a second distance, the first distance being greater than the second distance.

8 . The fertilizer opener according to claim 7 , wherein the plurality of apertures of the wheel bracket are configured to effectuate the conversion of each wheel between the first wheel position and the second wheel position.

9 . The fertilizer opener according to claim 8 , wherein the first wheel position of respective wheels is configured to position the wheel in relation to its corresponding blade such that the bottom edge of the blade extends at least three inches from the bottom edge of the wheel, and the second wheel position of each wheel is configured to position respective wheels in relation to its corresponding blade such that such that the bottom edge of the blade extends 1.5 to 3 inches from the bottom edge of the wheel.

10 . The fertilizer opener according to claim 1 , wherein respective opener assemblies further comprise a scraper removably coupled to the second end of the support arm and be so disposed as to scrape residue from its corresponding blade as the blade rotates through soil.

11 . A dual fertilizer opener movable in a working direction for opening a trench in soil, comprising:
a frame support having a first end and a second end, the first end coupled to a frame of a planting implement, and a second end having a first side and a second side; and a first opener assembly selectably pivotably coupled to the first side of the second end of the frame support and a second opener selectably pivotably coupled to the second side of the second end of the frame support, each of the first and second opener assemblies being configured to pivot independently from the other and comprising:
a support arm having a first end selectably pivotably engaged with the frame support and a second end engaged with an axle;
a blade selectably coupled to the axle and configured to rotate about the axle;
a wheel bracket comprising a plurality of apertures and selectably coupled to the axle at a first aperture of the plurality of apertures;
a wheel selectably coupled to the wheel bracket at a second aperture of the plurality of apertures and configured to rotate about an axis of the second aperture; and
a spring selectably pivotably coupled to the frame support and configured to provide a downforce to the respective opener assembly;
wherein the first opener assembly is coupled to the second end of the frame support such that the first opener assembly is offset from the second opener assembly along the frame support in the working direction.

12 . The fertilizer opener according to claim 11 , wherein the support arm of the first opener assembly comprises a jog bend such that the second end of the support arm is offset from the first end of the support arm along an axis perpendicular to the working direction toward the second opener assembly, and wherein the support arm of the second opener assembly comprises a jog bend such that the second end of the support arm is offset from the first end of the support arm along an axis perpendicular to the working direction toward the first opener assembly.

13 . The fertilizer opener according to claim 12 , wherein the jog bend of each support arm defines an offset region proximate the second end of the support arm, and wherein the blade and wheel of each opener assembly are configured to be positioned substantially within the respective offset region.

14 . The fertilizer opener according to claim 11 , wherein respective opener assemblies further comprise a scraper removably coupled to the second end of the support arm and be so disposed as to scrape residue from its corresponding blade as the blade rotates through soil.

15 . The fertilizer opener according to claim 11 , wherein the first opener assembly and second opener assembly are configured to be convertible between at least a first lateral position from the frame support and a second lateral position from the frame support along an axis orthogonal to the working direction, the second lateral position being further from the frame support than the first lateral position.

16 . The fertilizer opener according to claim 15 , further comprising one or more spacers configured to effectuate the conversion of the first opener assembly and second opener assembly from the first lateral position to the second lateral position.

17 . The fertilizer opener according to claim 11 , wherein the wheels of respective opener assemblies are configured to be convertible b
