The axis of the upper pulley is parallel to and located above the axis of the lower pulley, so that a major axis of the eliptical configuration of the retrieving belt is inclined at a predetermined angle with respect to the direction of travel of the cotton retrieving device so that the slotted cotton retrieving belt will open and then close upon tufts of cotton laying on the ground.

Abstract: An apparatus for removing dirt and debris from clumps of down cotton that are released from slots of a group of retrieving belts as the belts pass around a rotating pulley that causes the slots to open includes a first group of approximately semi-circular, parallel tines disposed adjacent to the portions of the belts passing around the pulley. A plurality of fingers extending from the pulley and between the belts into the region bounded by the first group of tines and the belts urges the released clumps slidingly along the tines, and apply forces that loosen dirt and debris, which pass between the tines. The clumps ejected from the upper end of the region are received by pegs of a rotating peg drum and are moved against a second group of approximately semi-circular, parallel tines. The pegs tend to "thump" the cotton clumps as they slide along the second group of tines, further breaking up dried mud and debris therein and causing it to pass outward between the tines of the second group.

Abstract: Lift arms are mounted upon a cotton module builder. Cotton harvested from the field is placed into a basket which sets upon a convex guide upon a trailer. The trailer is pulled by a tractor to the module builder alongside the arms. The guide, together with the basket, is moved laterally toward the module builder. The arms are actuated to lift the basket from the guide to above the module builder. As the basket moves above the module builder a trip upon the module builder unlatches a door formed by one of the sides of the basket allowing the cotton to fall from the basket into the module builder. After the cotton has emptied into the module builder the basket is returned to the guide upon the trailer. The basket on the trailer is then moved to a harvester and refilled with harvested cotton.
