Abstract: Corn shelling apparatus having a supporting frame and a receiving hopper mounted on its upper part, beneath the hopper there being at least one shelling unit made up of an inner drum and an outer counter-drum, the drum being fitted inside the counter-drum, and having a fan and chute for removing the impurities, the stripped corn cobs, and the kernels. The drum is cylindrical, the counter-drum is frusto-conical and has its larger diameter turned upwardly toward the receiving hopper; the axes of the drum and counter-drum are vertical, and the peripheral surfaces of the drum and counter-drum are made of rods. The rods of the drum are disposed parallel and skewed with respect to vertical axial sections of the drum, and the rods of the counter-drum are disposed along the generant of a cone. The apparatus has an inclined kernel-collecting plane member enveloping the counter-drum upon the supporting frame of the apparatus.
