ABSTRACT:
A cotton harvesting machine in which the cotton as stripped from the rows is fed from the strippers into a rotary screw or auger device from which it is blown by a high velocity primary air stream from a high speed rotary fan through a venturi throat into the main cotton discharge duct while, at the same time, the high speed rotary fan directs a high velocity secondary or auxiliary air stream through a combination separating chamber and auxiliary discharge duct into the main outlet or cotton discharge duct. A discharge outlet is provided at the bottom of the combination separation chamber and auxiliary or secondary discharge duct and green or unopened cotton bolls and foreign matter including sticks, stones, etc., are discharged from the combination separation chamber and auxiliary or secondary discharge duct onto the ground and are prevented from being blown into the main cotton discharge outlet or duct and thence into the trailer wagon from which they would be delivered to the cotton gin where they would do great damage to the cotton gin apparatus.
