Abstract:
In a cotton harvester adapted for movement over a field of cotton plants in a forward direction and having harvesting structure for removing material from cotton plants, a conveying system for moving the removed material to an outlet member, and a duct for moving the removed material upwardly and rearwardly from the outlet member toward a cotton receiving structure, the duct comprising:a main body having front and rear panels connected by fore-and-aft extending sides, the front and rear panels having an S-shaped configuration as viewed from a direction transverse to the forward direction, the panels being curved in the S-shaped configuration to lend strength to the duct and to spread the conveyed material uniformly within the duct; andwherein the main body has a width which increases in the upward direction so that the width of an upper end of the main body is at least approximately twice the width of a lower end of the main body, the main body having a fore-and-aft dimension between the front and rear panels which decreases in the upward direction generally proportionally to the increase in width in the upward direction so that cross sectional area of the main body stays approximately the same in the upward direction.
