Cotton harvester multi-piece duct structure for conveying cotton materials between a cotton harvesting row unit, arranged toward a lower end of the duct structure, and an inlet opening of an extendable/retractable basket assembly. Toward an upper end thereof, the duct structure has a distal end operably connected to a remaining portion of the duct structure to allow the distal end of the duct structure to period between an operational position, wherein an outlet end of the duct structure is in general registry with the inlet opening to the basket assembly, and a storage position, wherein the distal end of the duct structure is lowered from the operational position to facilitate transportation of the cotton harvester. A lock mechanism is also disclosed for releasably fastening the distal end of the duct structure in an operational position relative to the remaining portion of the duct structure.
A cotton harvester comprising a mobile frame, harvesting structure to remove cotton material from cotton plants as the harvester is driven across a field, a basket to receive and hold the cotton material removed by said harvesting structure, said basket including a lower basket portion mounted on the frame and an upper basket portion telescopically received by the lower basket portion for elevational movement between an elevated field working position and a retracted position, with said upper basket portion defining an inlet opening for said basket through which cotton materials enter said basket, and a multi-piece cotton elevating structure to convey cotton material from said harvesting structure to said inlet opening, when said upper basket portion is in a field working position, and with a distal end portion of said elevating structure being pivotal about a fixed generally horizontal axis relative to a remaining portion of said elevating structure, when said upper basket portion is in said retracted position, to reduce the overall height of the harvester and thereby promote transportation of the harvester.
A cotton harvester comprising an extended frame, a harvesting structure to remove cotton material from cotton plants as the harvester is driven across a field, an extendable/retractable basket assembly to receive and hold the cotton material removed by said harvesting structure, said basket assembly defining an inlet opening through which cotton materials enter said basket assembly when said basket assembly is in an extended position, and a multi-piece cotton elevating structure to convey cotton material from said harvesting structure to said inlet opening, said elevating structure including a distal end duct portion operably interconnected to a remaining portion of said elevating structure to allow said distal end duct portion to pivot about a fixed generally horizontal axis between an operational position, wherein an outlet end of said elevating structure is disposed in general registry with the inlet opening of said basket assembly, and a storage position, wherein the distal end duct portion is lowered from the operational position to promote transportation of the harvester.
A cotton harvester comprising a mobile frame, a plurality of harvesting units mounted at a forward end of said frame to remove cotton material from cotton plants as the harvester is driven across a field, an extendable/retractable basket assembly defining an inlet opening through which cotton material enters the basket assembly, and wherein each harvesting unit has arranged in operable combination therewith a multi-piece duct structure to direct cotton material from the respective harvesting unit to said inlet opening when said basket assembly is in an extended position, said multi-piece duct structure including a generally vertical section extending upwardly from the respective harvesting unit and a movable section disposed at a free end of said vertical section for movement between an operational position, wherein an outlet end of said movable section opens in a generally rearward direction toward the inlet opening, and a storage position, wherein the outlet end of said movable section is directed generally downwards, to reduce the overall height of the harvester thereby facilitating transportation thereof.
