A concave includes a frame and an array of threshing elements supported by the frame, the threshing elements being spaced apart and extending generally parallel to one another. The threshing elements each have formed on an upper portion thereof disposed adjacent to an upper portion of the frame a longitudinally-extending notch respectively defining an aggressive threshing edge. The threshing edges faces a direction opposite to the direction of rotation of a harvester rotor. The notch is recessed into the bar and disposed adjacent to the upper portions of the opposite members of the frame and facing opposite to a direction of movement of the rotor. The notch has a channel along an outer edge of the notch, the channel being filled with filler material having a differing hardness than a hardness of the bar.

A corn kernel remover includes a fixing groove. A fixing portion for fixing corns is disposed at one end of the fixing groove. The fixing portion is disposed on an inner surface of the fixing groove. Because the corn kernel remover is adopted to fix the corns and a tool for stripping the corns is used to perform the operation of stripping the corn kernels, the corn kernel remover is held directly, so as to effectively prevent the tool for stripping the corns from injuring hands, thereby ensuring safer operation of stripping the corn kernels and more efficient operation of stripping the corn kernels.

An attachment for connection to a harvester comprises a plurality of picking devices (2) arranged next to each other and in a distributed manner along the working width. Each picking device (2) has a picking gap (6), below which are disposed at least two picking rotors (10) which can be driven to rotate in opposite directions, the picking rotors (10) being provided with flutes (12), which project in a radial direction beyond the rotor casing (16) and the enveloping circles (20) of which mesh with each other. To propose a way of easily adapting the picking rotors to different harvesting conditions without having to replace them all, the invention proposes for one or more shear bars (18) which are releasably connected to the picking rotor (10) and/or to the flutes (12) to be inserted in the intermediate space (22) between adjacent flutes (12) of a picking rotor (10), the shear bars filling portions of said intermediate space during a rotating movement of the picking rotors (10).

A system and method for a sheller. The sheller has a receiver coupled to a pan. The receiver is hollow and coupled to a cap. A conveyor extends from a downstream end of the receiver. Spent cobs exit the receiver via the conveyor. The system further includes a plunger sized to be received by the receiver. The plunger is used to force ears of corn into the receiver.

A cutlery apparatus that is configured to provide efficient removal of corn kernels from a corn cob. The cutlery apparatus includes a support member that is planar in manner having an upper surface and a perimeter edge. A first brace member and a second brace member are mounted to the upper surface of the support member and further include a void therebetween. The first brace member and second brace member are parallel to each other and angularly oriented on the support member. A cutting member is provided wherein the cutting member has a first portion disposed within the void and a second portion extending beyond the perimeter edge of the support member. The second portion of the cutting member is a metal blade. A clamp member extends across the void and is movably secured to the first brace member and second brace member.

A dust restrictor is provided for eliminating dust and dirt accumulation between surfaces. The dust restrictor includes at least one dust restricting element and an attachment mechanism. The dust restricting element is disposed in a dust accumulating area of an arrangement. The attachment mechanism is provided for fixing each of the dust restricting elements to the dust accumulating area.

A corn harvester includes a first stalk roll having a plurality of first blades circumferentially spaced apart by a first angle. A second stalk roll has a plurality of second blades circumferentially spaced apart by a second angle. The first and second stalk rolls are rotatable about parallel first and second axes that are separated by a centerline therebetween. In an operational state when a tip of one first blade is aligned with the centerline, a tip of one second blade is angularly offset from the centerline by a third angle. The third angle is less than 45% of the second angle. The one first blade forms a cross section perpendicular to the first axis having an altitude extending from the tip toward the first axis along a first blade altitude. The cross section of the one first blade is asymmetric about the first blade altitude.
