Harvesting machine having non-circular extractor cleaning chamber

An extractor for a harvesting machine, the extractor comprising:

• a nozzle wall having an upper end and a lower end, the nozzle wall being outwardly and upwardly inclined at a first angle from the lower end to the upper end, the upper end being arranged at a first radius about a central axis, the lower end being arranged at a second radius about the central axis, the first radius being greater that the second radius;
• a first deflector plate and a second deflector plate positioned on opposing sides of the central axis and abut the nozzle wall, the first and second deflector plates each having a top wall, a bottom wall, and a face wall, the face wall extending between the top wall and the bottom wall and being planar, the first and second deflector plates being outwardly and upwardly inclined at a second angle from the bottom wall to the top wall, the second angle being different than the first angle,
• wherein the bottom wall of the first deflector plate defines a first straight sidewall of a profile of an inlet opening of the extractor, and the bottom wall of the second deflector plate defines a second straight sidewall of the profile of an inlet opening.

An extractor comprising:

• a fan assembly having a fan housing defining a cavity;
• and
• an extractor body that defines a chamber that extends from a first end of the extractor body to a second end of the extractor body, the chamber being in fluid communication with the cavity, the extractor body defining an inlet opening of the chamber at the first end, the inlet opening having a non-round shape, the extractor body further comprising at least one deflection plate assembly that defines at least opposing relatively straight side walls of the inlet opening, the second end being coupled to the fan assembly.
