Abstract: A system for removing plant material from harvested crops includes a pinch roller conveyor including pairs of rotatable pinch rollers whose longitudinal axes are aligned with a length of the conveyor, the pinch rollers forming nips in which plant material can be caught and pulled down through the conveyor as the pinch rollers rotate, wherein first ends of the pinch rollers are laterally displaceable so that the pinch rollers can laterally separate from each other to facilitate passage of plant material.

Abstract: A corn-shelling machine has a front head and a rear auger to collect and channel the cobs after shelling. The front head has at least one sheller roller fitted with blades to pull a stalk of a corn on the plant downwards. Sheller plates are positioned above the sheller roller, on the side opposite the ground. The sheller plates have an upper wall, opposite the ground and suitable to receive the cobs upon threshing and to retain them during the shelling phase. A blower generates a flow of air to channel the kernels of corn, removed from the cobs during shelling, towards the rear auger. The air flow is directed from the front head of the machine towards the rear auger.

Abstract: The system and method automatically controls the position of at least one deck plate of a harvesting unit of a corn header so as to increase the width of a stalk receiving channel or reduce pinching forces between the plates when entering a stand of corn to facilitate alignment with the corn rows, and to change the position after a suitable time period or other condition or event, to narrow the channel width and/or increase pinching force, to reduce kernel loss while also monitoring forces exerted against the plates by the stalks and responsively adjusting the plate position for maintaining a desired force on the stalks or width.
Abstract: The combine includes internal apparatus incorporated into a system for threshing corn kernels from cobs, positively de-husking the cobs, cleaning other crop residue or material from the kernels, and direct the cleaned kernels and de-husked cobs to desired locations. The de-husking apparatus can include a modified type of husking bed, and is disposed for receiving a flow of grain, cobs and other residue from threshing apparatus of the combine, and positively grasping and pulling the remaining husks from the cobs and downwardly through the husking bed for disposal such as by discharge from the combine onto a field, with or separately from the other residue.
Abstract: A stalk roll for an agricultural harvester row unit comprising a plurality of longitudinal extending knife edges about its circumference, in which one of the leading and trailing sides of the knife edges is coated with a first wear resistant coating over substantially its entire length, and in which the other of the leading and trailing sides is coated with a second wear resistant coating over at least one of a front portion thereof and a rear portion thereof.

Abstract: A gathering and picking unit for a harvesting assembly having a plurality of picking units. Each picking unit is provided with at least one picking roll. The picking rolls are rotatably mounted to the outer portion of a moving element that is rotated about a second vertical axis. Each picking roll is rotated about a first horizontal axis. The picking units can be arranged radially or tangentially on the moving element.
Abstract: A device for husking corn ears is disclosed. The device removes the husks and silks and at the same time avoids substantial damage to the kernels. The device includes a plurality of rollers and drive means which rotate the rollers at selected speeds in selected directions in a selected sequence. A method of husking corn comprising the steps of cutting the butt end off the ear, and positioning the ear between closely spaced rollers rotating in opposite directions to gently remove the husks is also disclosed.

Abstract: A corn husking machine has a hollow cylindrical drum defined by a circumferential wall rotatable about a substantially horizontal longitudinal axis. The drum wall has at least one aperture therethrough which is suitable for unhusked ears of corn to pass through from outside the drum to the hollow interior of the drum. A station is affixed to an interior portion of the drum wall adjacent each aperture and extends into the hollow of the drum. Each station has two elongated rollers positioned side by side, which are rotated in opposite directions, so that at a nip formed by adjacent surfaces of the rollers, husks of unhusked ears of corn passed through the adjacent aperture are seized by the rotating rollers and stripped off the ears and pulled between and through the nip. The husks are collected in a central portion of the hollow of the drum. For husking ears of minicorn, the rollers have a diameter of from 1 cm to 3 cm and are rotated at a speed of from 20 rpm to 250 rpm.
