Abstract
Air intake for trash removal apparatus of a cane harvester. The air intake forms the lower portion of the housing of the trash removal apparatus and also serves to guide cane billets into the hopper of a pivotally-mounted billet discharge conveyor. The air intake is formed as a deflectible air permeable curtain of perforated rubber sheeting which avoids both damage to the air intake and jamming of the conveyor during use.
