Abstract

Nozzles for an air duct arrangement of an air conveying system may include a first outlet nozzle that is divided into a plurality of chambers are disclosed. The plurality of chambers formed by the outlet provide for a more uniform flow of air exiting the outlet, which generates a greater induced air flow in an associated section of duct. An orientation of a second outlet relative to an inlet of the nozzle provides for a reduced head loss within the nozzle, thereby providing for reduced backpressure within the nozzle and, consequently, a reduced power consumption associated with generating a desired airflow through the nozzle.

First claim

What is claimed is:

1. A nozzle for an agricultural machine comprising:
a U-shaped body;
an inlet formed at a first end of the U-shaped body, the inlet defining a first datum plane having a first orthogonal coordinate system, the first orthogonal coordinate system comprising:
a first orthogonal axis,
a second orthogonal axis, and
a third orthogonal axis;

a first outlet formed at a second end of the U-shaped body opposite the first end, the first outlet having a height and a width that is perpendicular to the height, the first outlet defining a second datum plane; and
a second outlet formed in the U-shaped body and disposed between the inlet and the first outlet, the second outlet defining a third datum plane, the third datum plane being angularly offset from the first datum plane by a first angular amount within a range of 17.1° to 37.1° about a first line parallel to the first orthogonal axis of the first orthogonal coordinate system, by a second angular amount within a range of 6.9° to 13.1° about a second line parallel to the second orthogonal axis of the first orthogonal coordinate system, and by a third angular amount within a range of −4.1° to 15.9° about a third line parallel to the third orthogonal axis of the first orthogonal coordinate system.

2. The nozzle of claim 1 , wherein the first outlet is divided into a plurality of chambers.

3. The nozzle of claim 2 , wherein the first outlet is divided into two chambers by a partition.

4. The nozzle of claim 3 , wherein the U-shaped body comprises:
a first portion that includes the inlet;
a second portion that includes the first outlet; and
a transition portion extending between the first portion and the second portion.

5. The nozzle of claim 4 , wherein the partition extends along the second portion to the transition portion.

6. The nozzle of claim 4 , wherein the partition extends into at least partially into the transition portion.

7. The nozzle of claim 3 , wherein the partition defines an opening extending through the U-shaped body.

8. The nozzle of claim 1 , wherein the first outlet comprises an opening having an elongated shape.

9. The nozzle of claim 1 , wherein the inlet comprises an opening having a circular shape.

10. The nozzle of claim 1 , wherein the second datum plane is angularly offset from the first datum plane by approximately 30° about a line parallel to the first axis of the first orthogonal coordinate system.

11. The nozzle of claim 1 , wherein the transition portion transitions from an elongated cross-sectional shape to a circular cross-sectional shape.

12. The nozzle of claim 1 , wherein the first angular amount is approximately 27.1°.

13. The nozzle of claim 1 , wherein the second angular amount is approximately 13.1°.

14. The nozzle of claim 1 , wherein the third angular amount is approximately 5.9°.

15. The nozzle of claim 1 , wherein the first datum plane and the second datum plane are nonparallel.

16. The nozzle of claim 15 , wherein the first orthogonal axis is parallel with a line lying on the second datum plane that defines the width of the first outlet.
