A cotton stripper with an improved row unit having brush rolls and augers with parallel shafts driven by a gear drive. The parallel shafts permit the unit to be narrowed several inches compared with the conventional units. A cut-off member between the brush roll and auger has an edge which runs parallel to the shafts below the axis of the brush roll shaft to break up stalks and facilitate power feeding of stripped material toward the lower part of the auger. The auger housing is formed with angled flat walls for better stalk breakage. Upright forward slots and rear fore-and-aft extending slots in flat auger walls provide increased dirt and trash elimination. The top of the row unit housing is formed with a low friction material that is angled downwardly toward the row receiving area to reduce cotton loss. A separation chamber leading rearwardly from the cross auger outlet to the input of the main vertical duct is open on the bottom with several air assist tubes extending across the proximate end of the opening to float ripe cotton. The tubes have holes which open to direct air toward the main duct input above the distal end of the opening. A reduced output jet in the main duct sucks floated cotton from the chamber, while denser green bolls and other dense debris drop through the opening and out of the conveying path.
In a cotton harvester having a main frame supported for forward movement through a field of cotton planted in parallel rows, a row unit for stripping cotton from a row of plants and delivering stripped cotton and plant debris rearwardly to a main conveyor, and an upright duct having a bottom and an air jet located above the bottom of the duct for propelling cotton upwardly from the main conveyor, cotton separating and conveying structure comprising:
In a cotton conveying system having a first conveyor for directing ripe cotton and green cotton bolls to a conveyor outlet location, and a main duct for pneumatically conveying the cotton to cleaning structure, structure for separating dense material such as green cotton bolls from the ripe cotton comprising:
