ABSTRACT:
Bypass grate and door control structure for a cotton-cleaning machine mounted on a cotton harvester, and structure for spreading conveyed cotton uniformly across the width of the cleaning machine. A control linkage moves two grates, a door sheet, and an air door assembly in unison between cleaning and bypass mode positions. In the cleaning mode, cotton is directed downwardly from the air duct into the cleaning machine by the grates while air, fine dirt and trash are diverted through the grates and over the air door assembly away from the cotton basket. The cotton conveying duct and air nozzle are shaped to spread cotton uniformly across the upper portion of the duct, and diverging vane structure located above the cleaning machine distributes the downwardly directed cotton evenly across sawgrid type cleaners. An adjustable green boll opening below the grate structure permits heavy trash to drop from the conveying system to reduce gumming. In the bypass mode, cotton enters the basket directly from the cotton conveying duct.
