Patent number: 11399466Abstract: A threshing and separating system for an agricultural harvester includes a concave having a plurality of perforations; a rotor having an outer surface and at least partially enclosed by the concave; and a plurality of rasp bars connected to the outer surface of the rotor, each rasp bar having a working surface defining a working angle relative to a tangent of the outer surface. At least one of the rasp bars is an adjustable rasp bar with an adjustable working surface pivotably coupled to the rotor. The system further includes an actuator coupled to the adjustable rasp bar and configured to selectively pivot the adjustable working surface to adjust the working angle of the adjustable rasp bar.Type: GrantFiled: December 18, 2019Date of Patent: August 2, 2022Assignee: CNH Industrial America LLCInventors: Joris De Witte, Dré W.

Patent number: 11350573Abstract: A crank-operated packer mechanism includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings. The connection further includes a locking feature for locking the connection, such as a locking nut screwed onto a threaded outer end of the crank pins when inserted into the opening. Fixing of rotary bearings onto the crank pins is done by a fixing nut which at the same time serves as a disassembling aid for the spline connection. The crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced about its central rotation axis. Also a baler including the aforementioned packer mechanism.Type: GrantFiled: June 15, 2021Date of Patent: June 7, 2022Assignee: CNH Industrial America LLCInventors: Bart G. L.

Patent number: 11337372Abstract: A crank-operated packer mechanism includes a crank shaft including crank pins and crank arms. At least some of the crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced. The arms may, for example, be curved or hook-shaped. The crank shaft further includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings.Type: GrantFiled: June 15, 2021Date of Patent: May 24, 2022Assignee: CNH Industrial America LLCInventors: Bart G.

Patent number: 11277969Abstract: A threshing system for use in an agricultural harvester. The threshing system includes a rotor and a perforated concave system. The rotor has a rotational axis. The perforated concave system is spaced radially outwardly from the rotor for passage of grain through perforations as the rotor moves crop material across the concave system. The concave system has at least one concave section having a rigid frame, pivotal members, and an arcuate movable member. The rigid frame has a plurality of sides rigidly coupled together. The pivotal members are pivotally coupled and extend to two of the sides of the rigid frame. The arcuate movable member interacts with the plurality of pivotal members to pivot each of the pivotal members as the arcuate movable member is moved along a segment of an arc generally about the rotational axis.Type: GrantFiled: March 30, 2018Date of Patent: March 22, 2022Assignee: CNH Industrial America LLCInventors: Bart G.

Patent number: 10015930Abstract: An apparatus that controls the position of a component of a mechanical system, such as an adjustable concave in a combine harvester, while at the same time exhibiting a safety function that is reversible without requiring a long downtime of the combine. The apparatus includes a control part and an auxiliary part, both pivotable about the same axis, and a force transmission part to maintain these two parts in an assembled state by a spring force, as long as the component is subjected to forces below a given limit. When the forces exceed the limit, the auxiliary part and the control part are configured to become separated in such a manner that they can be reassembled by the intervention of an actuator. The safety function of the apparatus resembles the operation of a shear bolt.Type: GrantFiled: December 9, 2016Date of Patent: July 10, 2018Assignee: CNH Industrial America LLCInventors: Bart G. L.

Patent number: 9913431Abstract: An agricultural harvester including a chassis and a threshing and separating section for threshing and separating grain from gathered crop material. The threshing and separating section is carried by the chassis. The threshing and separating section includes at least one concave having a hooking feature, at least one sliding support, and a frame assembly for carrying and coupling the at least one concave thereto. The frame assembly includes a support bar allowing the hooking feature of the at least one concave to hook over the support bar to support one side of the at least one concave. Another side of the at least one concave is coupled to the frame assembly. The at least one sliding support supports the at least one concave as the at least one concave is moved toward or away from the support bar.Type: GrantFiled: May 27, 2016Date of Patent: March 13, 2018Assignee: CNH Industrial America LLCInventor: Bart G.

Patent number: 9622415Abstract: A cleaning system for a harvester has a sieve that is moveable by a drive assembly that includes a rotary drive, —an eccentric device, a transmission connected to the eccentric device and to the sieve, which transmission cyclically varies the distance between the driving point of the eccentric device and the sieve coupling during each full rotation of the rotatable output shaft of the rotary drive, wherein, due to the cyclic variation of the distance between the driving point of the eccentric device and the sieve coupling, during each reciprocating sieve movement at least one of the accelerating portion of the throw stroke, the decelerating portion of the throw stroke, the accelerating portion of the return stroke and the decelerating portion of the return stroke has a duration that is different from the duration of at least one other of the portions of the reciprocating sieve movement.Type: GrantFiled: April 16, 2015Date of Patent: April 18, 2017Assignee: CNH Industrial America LLCInventors: Frank R.
