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.
Claims16
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.
