Corn-shelling machine able to harvest the kernels from the cob, the machine having a front head able to shell the cobs and a rear auger able to gather and channel the cobs after shelling, wherein - the front head comprises at least one sheller roller rotating in relation to a relative rotation axis (X-X) so as to pull downwards the cobs, - the at least one sheller roller extending from a front extremity facing towards the front head, to a rear extremity, facing towards the rear auger, - the at least one sheller roller being fitted with blades to pull a stalk of a corn on the cob plant downwards, - the machine being fitted with sheller plates, positioned above said at least one sheller roller, on the side opposite the ground, the sheller plates having an upper wall, opposite the ground able to receive the cobs upon thrashing and to retain them during the shelling phase, and a lower wall, opposite the upper wall flanking the ground, - the sheller plates being distanced so as to identify, between respective lateral rims, a cavity suitable for permitting the passage of the stalk and preventing the passage of the cobs, during the shelling of the same, wherein - the machine comprises blowing devices which generate and send a flow of air to channel the kernels of corn removed from the cobs during shelling, characterised by the fact that said air flow is directed from the front head of the machine towards the rear auger, wherein nozzles are attached directly below the sheller plates, on said lower walls of the sheller plates, wherein the nozzles are inclined upwards, away from the ground, so as to direct the air flows above the sheller plates, on the side of the upper wall, towards the rear auger, wherein the direction of the jets of air generated by the nozzles is opposite to the shelling direction of the cobs, so that the cobs are pulled towards the ground while the jets are directed upwards to oppose the falling movement of the kernels caused by the rollers, wherein the corn-shelling machine further comprises channelling blades, positioned above the upper wall of the sheller plates, said channelling blades being provided with a substantially translatory movement from the front end to the rear end of the sheller rollers, so as to push the cobs to flow onto the sheller plates towards the rear auger, wherein the nozzles keep the kernels suspended near the sheller plates on the side of the upper wall so that the kernels can be intercepted by the channelling blades and channelled together with the cobs towards the rear auger. - the front head comprises at least one sheller roller rotating in relation to a relative rotation axis (X-X) so as to pull downwards the cobs, - the at least one sheller roller extending from a front extremity facing towards the front head, to a rear extremity, facing towards the rear auger, - the at least one sheller roller being fitted with blades to pull a stalk of a corn on the cob plant downwards, - the machine being fitted with sheller plates, positioned above said at least one sheller roller, on the side opposite the ground, the sheller plates having an upper wall, opposite the ground able to receive the cobs upon thrashing and to retain them during the shelling phase, and a lower wall, opposite the upper wall flanking the ground, - the sheller plates being distanced so as to identify, between respective lateral rims, a cavity suitable for permitting the passage of the stalk and preventing the passage of the cobs, during the shelling of the same, - the machine comprises blowing devices which generate and send a flow of air to channel the kernels of corn removed from the cobs during shelling, characterised by the fact that
