DETAILED DESCRIPTION

FIG. 1 illustrates a cotton harvester 10 according to one embodiment. The illustrated cotton harvester 10 is a cotton stripper 15.

The cotton harvester 10 includes a chassis 20. The chassis 20 is supported by front wheels 25 and rear wheels 30. The harvester 10 is adapted for movement through a field 35 to harvest cotton. An operator station 40 is supported by the chassis 20. A power module 45 may be supported below the chassis 20. The chassis 20 is generally similar to that shown and described in commonly assigned U.S. Pat. No. 7,631,716, the entire contents of which are hereby incorporated by reference. However, the operator station 40 is moved forward around thirty inches on the chassis 20 to provide more space behind the operator station 40. Other operator station 40 positions on the chassis 20 are contemplated by this disclosure.

A harvesting structure 50 is coupleable to the chassis 20. The harvesting structure 50 includes an auger housing 55 that is adjustably supported for vertical movement relative to the field 35. The harvesting structure 50 is configured to remove cotton from the field 35. The illustrated harvesting structure 50 includes a plurality of stripper row units 60. Eight to twelve stripper row units 60 are contemplated by this disclosure. More than twelve stripper row units 60 are also contemplated by this disclosure. Each stripper row unit 60 includes a row-receiving area 65 with conventional counter-rotating brush structure driven by hydraulic pressure for removing cotton plant material including cotton burrs and cotton fibers from cotton plants. The removed material is conveyed rearwardly by stripper row unit augers 70 in the stripper row units 60 to cross auger structure 75 (FIG. 2).

With reference to FIG. 2, the cross auger structure 75 includes a first cross auger 80. A first portion 85 of the first cross auger 80 includes a left-hand flighting 90. A second portion 95 of the first cross auger 80 includes a right-hand flighting 100. The left-hand flighting 90 and the right-hand flighting 100 are configured to move cotton towards a center portion 105 of the first cross auger 80. Alternatively, the first portion 85 may include right-hand flighting 100 and the second portion 95 may include left-hand flighting 90 and the first cross auger 80 may be rotated in an alternate direction.

The cross auger structure 75 includes a second cross auger 110. A first portion 115 of the second cross auger 110 includes a left-hand flighting 120. A second portion 125 of the second cross auger 110 includes a right-hand flighting 130. The left-hand flighting 120 and the right-hand flighting 130 are configured to move cotton towards a center portion 135 of the second cross auger 110.

A first duct 140 is coupleable to the cross auger structure 75. The first duct 140 is in communication with the first cross auger 80 and configured to receive cotton therefrom.

Referring to FIG. 1, a first cleaner 145 is in communication with the first duct 140. The first cleaner 145 is configured to receive cotton from the first duct 140 and remove debris from the cotton as shown and described in commonly assigned U.S. Pat. No. 5,806,290, the entire contents of which are hereby incorporated by reference.

With reference to FIG. 2, a second duct 150 is coupleable to the cross auger structure 75. The second duct 150 is in communication with the second cross auger 110 and configured to receive cotton therefrom.

Referring to FIG. 1, a second cleaner 155 is in communication with the second duct 150. The second cleaner 155 is configured to receive cotton from the second duct 150 and remove debris from the cotton as shown and described in commonly assigned U.S. Pat. No. 5,806,290, the entire contents of which are hereby incorporated by reference.

An accumulator 160 is in communication with the first cleaner 145 and the second cleaner 155. The accumulator 160 is configured to receive cleaned cotton from the first cleaner 145 and the second cleaner 155.

A feeder 165 is coupleable to the chassis 20. The feeder 165 is configured to receive cotton from the accumulator 160. The feeder 165 is configured to compress the cotton via a plurality of rollers and transfer the cotton to a receptacle 170.

The illustrated receptacle 170 is a round module builder 175 that includes a first module-forming portion 180 in communication with the feeder 165 for receiving the cotton therefrom. A second module-forming portion 185 is pivotally coupleable to the first module-forming portion 180. An extendable and retractable cylinder 190 is coupleable to the second module-forming portion 185. The extendable and retractable cylinder 190 is configured to pivot the second module-forming portion 185 relative to the first module-forming portion 180. The first and second module forming portions 180, 185 of the round module builder 175 are configured to form a round module or bale of cotton.

With continued reference to FIG. 1, a module handling system 195 is positioned adjacent the round module builder 175 for receiving the round module. The module handling system 195 temporarily supports the round module and then discharges it from the cotton harvester 10.

In operation, the cotton harvester 10 is driven through the field 35 to harvest cotton. The illustrated harvesting structure 50 strips cotton from cotton plants in the field 35. Cotton is transferred by the first duct 140 and the second duct 150 to the first cleaner 145 and the second cleaner 155 where debris is removed. The first duct 140, the second duct 150, the first cleaner 145, and the second cleaner 155 enable the cotton harvester 10 to harvest more cotton at a higher rate of speed compared to a cotton harvester with only one cleaner. Additional ducts and cleaners are contemplated by this disclosure in order to provide maximum productivity and non-stop harvest. Cotton is then transferred to the accumulator 160. The accumulator 160 holds the cotton until a predetermined cotton level is reached and then transfers the cotton to the feeder 165. In an exemplary embodiment, the accumulator 160 transfers cotton to the feeder 165 four times for each round module produced. When the feeder 165 receives cotton, the plurality of rollers is activated to compress the cotton. The compressed cotton is transferred to the round module builder 175.

After the round module builder 175 receives compressed cotton, the compressed cotton is rotated into the round module. Once the round module has been wrapped, the second module-forming portion 185 is pivoted relative to the first module-forming portion 180, and the round module can be ejected onto the module handling system 195. The module handling system 195 supports the round module and then discharges it from the cotton harvester 10.
