The invention relates to the technical field of agricultural machinery and discloses a multichannel corn husker comprising a frame, a husking mechanism, a husking roll power unit and a husking roll power transmission unit. The husking mechanism is mounted within a husking roll fixture and comprises upper husking rolls and lower husking rolls which are parallel to each other. The frame comprises a fixed support and a lifting support provided over the fixed support. The husking roll fixture is mounted at the top of the lifting support. A plurality of corn husking passage groups composed of the upper husking rolls and the lower husking rolls meshing with the upper husking rolls are provided in an inner chamber of the husking roll fixture. A swing-shifting mechanism is provided over the husking mechanism which is obliquely arranged; the feed end of the swing-stirring mechanism is higher than the discharge end thereof. The swing-stirring mechanism stably swings side to side so that corn ears are neatly arranged; the structure and combination of the husking rolls helps effectively increasing husking rate of corn ears and decreasing damage of scattering kernels.
