Patent number: 11039573Abstract: An automatic uniform distribution apparatus for the threshed material from the combine harvester comprises a tangential flow threshing and separating device, a shaking plate threshed material detecting device, a shaking plate, a shaking plate flow guiding mechanism, an axial flow threshing and separating device, a chaff screw conveyor, a return plate, a return plate flow guiding mechanism, a return plate threshed material detecting device, a vibrating sieve, and an on-line detection controller. Force sensors are provided at lateral positions below discharge ports of the shaking plate and the return plate to measure flow rates of the threshed material in lateral regions of the shaking plate and the return plate.Type: GrantFiled: July 13, 2018Date of Patent: June 22, 2021Assignee: Jiangsu UniversityInventors: Lizhang Xu, Ying Zhou, Yaoming Li, Zhong Tang, Zheng Ma

Patent number: 10212888Abstract: A sieve system of an agricultural vehicle for separating crop residue from grain, the sieve system including a frame, a plurality of sieve sections, a plurality of dividers and a pivoting system. The sieve sections are pivotally coupled to the frame. The sieve sections include a first sieve section. The dividers include a first divider coupled to the first sieve section. The pivoting system is coupled to the first sieve section and the first divider, to thereby pivot the sieve section at a first angle about a first axis. The pivoting system also either pivots the divider at a second angle about a second axis or flexes the divider at the second angle. The first angle is relative to the frame, and the second angle is relative to the sieve section.Type: GrantFiled: February 8, 2017Date of Patent: February 26, 2019Assignee: CNH Industrial America LLCInventor: Jonathan E. Ricketts

Patent number: 10045482Abstract: A crop residue spreader has a plurality of deflector elements arranged in a first group and a second group, a planar spreader frame element having a bottom surface to which the first and second group of deflector elements are displaceably mounted, the planar spreader frame element comprising a guide slot extending in a direction substantially perpendicular to the longitudinal axis, a first cover plate that is displaceably mounted to a top surface of the planar spreader frame element; a second cover plate that is displaceably mounted to the top surface of the planar spreader frame element and whereby a relative displacement of the first and second cover plates away from each other causes a part of the guide slot to be uncovered and a third cover plate is configured to cover, at least partly, the uncovered part of the guide slot.Type: GrantFiled: January 5, 2016Date of Patent: August 14, 2018Assignee: CNH Industrial America LLCInventors: Stefaan Ballegeer, Stefaan Desmet

Patent number: 9854742Abstract: A combine harvester including a grain pan arranged to catch a crop stream from threshing or separating apparatus. The grain pan is driven in an oscillating manner to convey the crop stream rearwardly to a rear edge. A cleaning unit including a fan for generating a cleaning airstream which is directed under the rear edge of the grain pan. The grain pan comprises includes a transversely corrugated surface and longitudinal gullies having a curved profile for compensating for side-hill operation.Type: GrantFiled: December 15, 2015Date of Patent: January 2, 2018Assignee: AGCO International GmbHInventor: Morten Leth Bilde

Patent number: 5085616Abstract: A cleaning system for a combine including a fan and reciprocal sieves mounted within a housing of the combine. The sieves include a series of transversely extending slats which are selectively adjustable to allow clean grain to pass therethrough. A plurality of transversely adjacent baffles extend in a fore-and-aft direction along substantially the entire length of and for a relatively short distance above an upper distance of the sieves. The baffles have a cumulative effect of inhibiting a disproportionate granular accumulation of granular material adjacent the downhill side of the sieves when the harvesting apparatus is tilted during slope harvesting. Each of the baffles are movable conjointly with and in response to adjustment of the slats of the sieves.Type: GrantFiled: February 13, 1991Date of Patent: February 4, 1992Assignee: Case CorporationInventors: Robert A. Matousek, Jon E. Ricketts

Patent number: 4921469Abstract: A distributing device for chaff choppers for attachment to mowing-threshing machines has a top cover plate, beneath which right and left groups of baffles are arranged next to one another, preferably at right angles to the cover plate. The baffles are pivotably supported around axles at their ends facing the chopper and spaced therefrom, while being rigidly connected by guide bolts penetrating guide slots in the cover plate or in the machine casing. A set bar is associated with each group of baffles. The baffles are connected with each other by the guide bolts which are rotatable in fixed bearings and by two guide rails, and, at their ends facing the chopper, rotatably and displaceably arranged in points on the cover plate. The guide slots of each group extend displaced relative to each other in a transverse direction, substantially parallel to each other and to a line through the axles.Type: GrantFiled: November 16, 1988Date of Patent: May 1, 1990Assignee: BISO Bitter, GmbH & Co.Inventor: Alois Scharf

Patent number: 4897071Abstract: A combine harvester having a threshing and separating mechanism and a grain cleaning mechanism disposed beneath the threshing and separating mechanism and including a grain pan fitted with a movable divider apparatus and operable to receive grain from the threshing and separating mechanism, sieve mechanism operable to receive grain from the grain pan, and a fan operable to blow air through the sieve mechanism, is disclosed wherein an inclination sensing mechanism for sensing the lateral inclination of the combine harvester is operatively associated with an actuator operatively coupled to the grain pan divider apparatus for positionally adjusting the grain pan divider apparatus in response to the output of the inclination sensing mechanism to compensate for any given lateral inclination of the harvester.Type: GrantFiled: October 20, 1988Date of Patent: January 30, 1990Assignee: Ford New Holland, Inc.Inventors: Dirk J. Desnijder, Wilfried E. D. Gunst, Willy C. Hollevoet, Marc R. M. Jonckheere, Francois Van Herpe
