Abstract

An apparatus for removing the husks from ears of corn has axially extending rotatable molded rubber rolls. Each roll has a plurality of aligned axially extending flights which protrude from a cylindrical base segment. The flights may extend exclusively axially, or may extend circumferentially as well to define a segment of a helix. The flights of adjacent rolls are meshed with one another, and the rolls are rotated toward one another to engage husks therebetween. Portions of one or both rolls define a helical recess which extends the length of a roll. A continuous rib may extend from the base segment and is aligned between two flights and extends above the base segment, the rib extends through the helical recess, and engages husks within the recess of an adjacent roll. The continuous rib may be internally reinforced with a metal blade. The roll recesses provide relief for larger diameter trash and stalks, alleviating the flexing of the roll axles which might otherwise occur. The helical recesses act as an auger which engages and advances Stalks gripped in the helical recesses and moves them forward at a rate taster than the progress of the ears such that the stalks are either discharged beneath the roll bed or carried along by the recesses to the discharge end of the apparatus.
