Publication number: 20240065173Abstract: A cleaning system for an agricultural combine harvester includes a pan and a crop divider. The pan includes a stepped floor to receive crop material thereon and is arranged for fore-aft reciprocating movement to advance the crop material in a crop-processing direction. The crop divider is mounted with the pan for fore-aft reciprocating movement therewith and extends in a fore-aft manner and above the stepped floor to partition the crop material laterally. The crop divider includes a body and a periphery disposed about the body. The body includes a multi-dimensional, clustered array of crop strokers extending laterally to engage the crop material to advance the crop material in the crop-processing direction during fore-aft reciprocating movement of the pan.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventors: Kiran Kumar Mayya, Yogesh N.

Publication number: 20240023483Abstract: A cleaning assembly for a combine harvester. The cleaning assembly includes a conveyor for transporting at least one of or both of a threshed or separated mixture of grain and contaminants from at least one of or both of a threshing or separating device to an inlet of the cleaning assembly, screens for cleaning the mixture fed to the inlet of the cleaning assembly, which are able to be subjected to the action of an air flow by a fan, and a cross conveyor, arranged at the inlet of the cleaning assembly, for evening out the lateral distribution of the fed mixture. The cross conveyor is implemented with an open, air-permeable design and is arranged in an air flow provided by the fan.Type: ApplicationFiled: July 10, 2023Publication date: January 25, 2024Inventors: Daniel Jung, Martin Rittershofer, Kevin P.

Patent number: 11510369Abstract: Systems and methods for automatically establishing a gap between a concave and a rotor of a rotary crop processing system are disclosed. Establishing the gap may include displacing the concave towards the rotor until contact is detected therebetween. Contact may be detected using a sensor configured to detect contact between the rotor and the concave. The sensor may be a knock sensor. The concave is displaced away from the rotor when contact is detected until contact between the rotor and the concave is no longer detected. One or more actuators may be coupled to the concave to move the concave relative to the rotor. In some implementations, the actuators may be operated in sequence to form the gap between the rotor and the concave.Type: GrantFiled: March 10, 2020Date of Patent: November 29, 2022Assignee: Deere & CompanyInventors: Eric L. Bortner, Kevin P. Hurley, Michael Meschke

Patent number: 11013180Abstract: A harvester includes a chassis, a separation frame movably supported by the chassis and upon which crop material is deposited, a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame, a control system, a sensor programmed to produce a signal indicative of a tilt of the chassis relative to a gravitational direction, and programmed to provide the signal to the control system, and an adjustable link operably coupled between the separation frame and the chassis to adjust a pivot point of the separation frame. The control system is programmed to determine a change in tilt of the chassis based on the signal from the sensor. The controller is programmed to adjust the adjustable link to modify the pivot point of the separation frame in response to the change in tilt of the chassis.Type: GrantFiled: August 30, 2019Date of Patent: May 25, 2021Assignee: DEERE & COMPANYInventors: Karthikeyan Narayanan, James K.
