Abstract
Cotton accumulator structure includes an upright storage area supported behind the cab of a cotton harvester. A screened upper cover area is supported above the storage area by hydraulic cylinders which move the cover between a raised harvest position and a lowered storage position for reduced transport height. As harvested material is directed through ducts towards the storage area, debris can exit through the screened cover. The lower end of the storage area includes an opening for egress of the cotton. Several shafts having timed projections are journalled for rotation adjacent the opening about parallel axes. The shafts, when not rotating, generally close the lower end and prevent cotton from falling through the opening. To meter the cotton from the storage area to an operating on-board processor, a drive is activated to rotate the shafts. Preferably, the shafts are driven in counter-rotating fashion so that a given shaft rotates in the opposite direction from the next adjacent shaft, and projections on the shaft pull cotton from the storage area. Cotton is uniformly distributed from the storage area onto a belt extending from the processor which preferably is part of a compact…
