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: 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. L. Van Hullebusch, Johan A. Van der Haegen

Patent number: 10034430Abstract: A combine harvester including at least one straw walker extending in a longitudinal direction of the harvester and supported by a front and rear shaft. The shafts are rotatable about respective rotation axes, and each shaft provided with one or more eccentric portions. The straw walker is rotatably mounted on an eccentric portion of the respective front and rear shafts, so that the simultaneous rotation of the shafts actuates a reciprocating motion of the straw walker. The combine further comprises a pivot frame and one or more actuators, configured to adjust the angular position of the frame by pivoting the frame about a pivot axis oriented transversally to the longitudinal direction. The front and rear shafts are configured to rotate with respect to the pivot frame, so that the straw walker's angular position is adjustable while the straw walker executes the reciprocating motion.Type: GrantFiled: June 30, 2016Date of Patent: July 31, 2018Assignee: CNH Industrial America LLCInventors: Bart M. A. Missotten, Johan A. Van der Haegen, Michiel Vanderstichele, Koen Landschoot

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. Van Hullebusch, Frank R. G. Duquesne, Johan A. Van Der Haegen

Patent number: 9814179Abstract: A combine harvester has an inclination module coupled to the straw walker control system. The inclination module provides information on the inclination of the combine harvester. The straw walker control system is further configured to control the controllable frequency of the oscillating movement in function of the information on the inclination of the combine harvester.Type: GrantFiled: January 2, 2014Date of Patent: November 14, 2017Assignee: CNH Industrial America LLCInventors: Frank R.

Patent number: 9788491Abstract: A rotor housing assembly for a harvester has at least one cover plate forming part of a generally cylindrical shaped rotor housing, a central longitudinal axis, and an inner surface, which, when mounted, faces the central longitudinal axis and has a first radius, and one or more rotatable vanes which each are rotatably mounted on an inner surface of the cover plate facing the central longitudinal axis at a rotation point. The one or more rotatable vanes have a contact surface with the inner surface. The contact surface has a second radius that is larger than the first radius of the cover plate. The inner surface of the top cover plate, per rotatable vane, has a symmetrically curved shape such that, during a rotation of the respective vane, the contact surface of the vane with the inner surface of the cover plate substantially follows the shape of the inner surface.Type: GrantFiled: March 6, 2014Date of Patent: October 17, 2017Assignee: CNH Industrial America LLCInventors: Frank R. G. Duquesne, Philip Maenhout, Bart M. A. Missotten, Johan A. Van Der Haegen
