The invention relates to agricultural machinery, in particular to a peeling mechanism for removing bracteal leaves from fresh corn ears, in particular to a device for efficiently peeling corn ears at a low smashing rate. The device comprises a feeding hopper, a discharging hopper, a transmission system and a frame, wherein the frame is provided with an engine base; the engine base is provided with a peeling roller device; the peeling roller device comprises at least two pairs of peeling rollers which are meshed in parallel with each other; the peeling rollers consist of fixed peeling rollers and floating peeling rollers; the surface of each fixed peeling roller is provided with metal strip-shaped spiral bumps and inverted V-shaped bracteal leaf cutting teeth; the floating peeling roller close to one side of the feeding hopper is provided with rasp bar-shaped peeling teeth; and the other side is provided with rubber trapezoidal peeling teeth. The device is particularly suitable for fresh corns (such as fruit corns, waxy corns and sweet corns) with high moisture and tight bracteal leaves, fodder corns, corn seeds and the like, and has a good peeling effect, high efficiency and low smashing rate.
