Abstract

A seed tank assembly for an agricultural implement including an exhaust opening configured to exhaust seeds from the seed tank assembly. The seed tank assembly further including at least one angled rib molded into the seed tank assembly, in which the at least one angled rib is configured to provide structural rigidity to the seed tank assembly and to direct the seeds toward the exhaust.

Claims

1. A seed tank assembly for an agricultural implement comprising:

an exhaust opening that extends partially along a longitudinal extent of the seed tank assembly such that a longitudinal extent of the exhaust opening is substantially parallel to the longitudinal extent of the seed tank assembly, wherein the exhaust opening is configured to exhaust seeds from the seed tank assembly; and

the first angle is between 10 degrees and 60 degrees;

the second angle is between 30 degrees and 80 degrees;

the first angled rib is configured to;

provide structural rigidity to the seed tank assembly; and

redirect first seed in the seed tank assembly from a first flow path toward a first portion of the exhaust opening to a second flow path toward a second portion of the exhaust opening, different from the first portion of the exhaust opening; and

the first angled rib comprises;

a tapered end at a first distal end of the first angled rib, wherein the a tapered end is configured to facilitate separating the first seed from second seed directly adjacent the first seed in the first flow path; and

a rounded end at a second distal end opposite the first distal end.

2. The seed tank assembly of claim 1, wherein:

the first angle is between 10 degrees and 20 degrees relative to the first plane and the second angle is between 70 degrees and 80 degrees relative to the second plane;

the first angle is between 20 degrees and 30 degrees relative to the first plane and the second angle is between 60 degrees and 70 degrees relative to the second plane;

the first angle is between 30 degrees and 40 degrees relative to the first plane and the second angle is between 50 degrees and 60 degrees relative to the second plane;

the first angle is between 40 degrees and 50 degrees relative to the first plane and the second angle is between 40 degrees and 50 degrees relative to the second plane;

or

the first angle is between 50 degrees and 60 degrees relative to the first plane and the second angle is between 30 degrees and 40 degrees relative to the second plane.

3. The seed tank assembly of claim 1, wherein:

the first portion of the exhaust opening corresponds to a distal portion of the exhaust opening; and

the second portion of the exhaust opening corresponds to a middle portion of the exhaust opening.

4. The seed tank assembly of claim 1, wherein:

the first portion of the exhaust opening comprises a first aperture of the exhaust opening; and

the second portion of the exhaust opening comprises a second aperture of the exhaust opening.

5. The seed tank assembly of claim 1, wherein the second angle is a complement of the first angle.

6. A seed tank assembly for an agricultural implement comprising:

an exhaust opening that extends partially along a longitudinal extent of the seed tank assembly such that a longitudinal extent of the exhaust opening is substantially parallel to the longitudinal extent of the seed tank assembly, wherein the exhaust opening is configured to exhaust seeds from the seed tank assembly, and the exhaust opening comprises a distal longitudinal portion and a central longitudinal portion, different than the distal longitudinal portion; and

a first rib molded into a wall of the seed tank assembly at a first angle relative to a first plane perpendicular to the longitudinal extent of the exhaust opening and at a second angle relative to a second plane perpendicular to a lateral extent of the exhaust opening, wherein;

the first angle is between 10 degrees and 60 degrees;

the second angle is between 30 and 80 degrees;

the first rib is configured to;

provide structural rigidity to the seed tank assembly; and

redirect a portion of the seeds in the seed tank assembly from a first flow path to a second flow path to enhance uniformity of seed distribution between the distal longitudinal portion of the exhaust opening and the central longitudinal portion of the exhaust opening; and

the first rib comprises;

a tapered end at a first distal end of the first rib, wherein the tapered end is configured to facilitate separating the second flow path from the first flow path; and

a rounded end at a second distal end opposite the first distal end.

7. The seed tank assembly of claim 6, wherein:

the first angle is between 10 degrees and 20 degrees relative to the first plane and the second angle is between 70 degrees and 80 degrees relative to the second plane;

or

the first angle is between 50 degrees and 60 degrees relative to the first plane and the second angle is between 30 degrees and 40 degrees relative to the second plane.

8. The seed tank assembly of claim 6, wherein the exhaust opening is substantially rectangular and comprises a plurality of substantially rectangular apertures.

9. The seed tank assembly of claim 6, wherein:

the first flow path is toward the distal longitudinal portion of the exhaust opening; and

the second flow path is toward the central longitudinal portion of the exhaust opening.

10. The seed tank assembly of claim 6, wherein the second angle is a complement of the first angle.

11. A seed tank assembly for an agricultural implement comprising:
