A cotton harvester having a harvesting head assembly mounted to a chassis of the harvester for generally vertical movement. The harvesting head assembly includes a plurality of harvesting units for removing a commingled mixture of materials including trash and cotton from plants as the harvester is driven across a field, and a cleaning mechanism for receiving and processing the commingled mixture of materials received from the harvesting units thereby separating trash from cotton as the harvester moves across the field. The cleaning mechanism is mounted between the harvesting units and a discharge area on the head assembly to facilitate the flow of cotton materials to a cotton receiving receptacle and increase the holding capacity of the receptacle by eliminating trash that normally flows thereto as a result of the harvesting operation.
A cotton harvester having a fore-and-aft extending chassis adapted for movement across a cotton field, a harvesting head assembly laterally extending across and supported on the chassis, a duct carried on the chassis for directing materials toward a receptacle, said duct including an inlet arranged in receiving relation relative to said head assembly, an air system for creating an air flow within said duct to facilitate movement of materials toward said receptacle, and wherein said harvesting head assembly includes a plurality of harvesting units for harvesting materials including a commingled mixture of trash and cotton materials as the harvester is driven across the field, a rotatably driven auger extending rearwardly and across the harvesting units, and cleaning means for receiving harvested materials from the harvesting units for cleaning whereby at least a portion of the trash and the like is separated from cotton materials before the cotton materials are moved to the auger thereby enhancing efficiency of said air system in moving materials toward said receptacle.
A cotton harvester having a mobile chassis and a harvesting head assembly laterally extending across and supported on said chassis, said harvesting head assembly comprising a rotatably driven auger means laterally extending across said chassis, harvesting means for removing a commingled mixture of trash and cotton materials from the plants, and means interposed between said harvesting means and said auger means for separating at least a portion of the trash and the like from cotton materials before the auger means receives the cotton materials.
A cotton harvester for harvesting cotton materials from a plurality of rows of cotton plants planted in generally parallel rows in a field, the harvester comprising a fore-and-aft extending chassis adapted for movement over the field, a harvesting head assembly extending laterally across a forward end of said chassis, cotton conveying duct means arranged in cotton receiving relation to and extending upwardly from the harvesting head assembly and toward a receptacle, and wherein said harvesting head assembly comprises a support structure connected to said chassis for generally vertical movement relative to said chassis, a plurality of fore-and-aft extending harvesting units individually connected to said support structure and arranged in side-by-side relation for harvesting materials in a commingled mixture of cotton materials and trash from the plants as the harvester is driven across the field, with at least two of said plurality of harvesting units being arranged on opposite lateral sides of a longitudinal center of said chassis, rotatably driven auger means arranged on said support structure to extend rearwardly across and below an exhaust end of said harvesting units for gathering and conveying materials toward a discharge area, means for processing the commingled mixture of materials received from all the harvesting units, said processing means including rotatable means for separating cotton from the commingled mixture of materials received from the harvesting units, and means for doffing cotton from the separating means and delivering the cotton to said auger means for deliverance to said receptacle.
A cotton harvester including a mobile chassis and a harvesting head assembly supported across the chassis and adapted to be moved vertically relative to said chassis by a pair of hydraulically powered arms pivotally connected to and extending forwardly from said chassis, rotatably driven auger means carried by said head assembly, harvesting means carried on said head assembly for vertical movement therewith, said harvesting means removing a commingled mixture of materials including trash and cotton from plants as the harvester moves across a field, and cleaning means carried by and movable with the head assembly for gravitationally receiving and processing the commingled mixture of materials from the harvesting means thereby separating trash from cotton as the harvester moves across a field.
