A shaker table with air flow openings and airflow to preprocess the crop before it fully enters the separating and cleaning system of the harvester through a means of corrugation platforms with air flow directed from below to break up the material into a more easily cleaned condition.

The present application for patent of invention refers to a device designed to thresh agricultural products. The agricultural products it is designed to process include grains in general, particularly peanuts and beans, but not limited thereto, and can be applied to other similar crops. The invention comprises a cylinder (1) that has a larger diameter zone (2) and smaller diameter zone (3), said larger or smaller diameter zones intermediated by a transition zone (4); in the smaller diameter zone (3) the helical path is contoured by rigid scale-like components (6) as far as part of the transition zone (4), where flexible elements are applied (7) following the entire length of the larger diameter zone (2), completing the (1) cylinder or rotor, and the flexible elements (7) can be arranged in consecutive way or interspersed, so that the interval between the flexible elements (7) is intermediated by substantially upside-down U-shaped elements (7B).

An agricultural harvester includes a chassis; a threshing and separating system carried by the chassis and including at least one threshing rotor mounted in a longitudinal direction of the agricultural harvester; a grain pan carried by the chassis that receives crop material from the threshing and separating system, the grain pan being configured to shake in a fore-to-aft direction and a lateral direction; and a cleaning system carried by the chassis supplied with crop material from the grain pan, the cleaning system including at least one sieve configured to shake in the lateral direction out of phase with the grain pan.

A combine harvester includes one or more threshing rotors (5) mounted in the harvester, a grain pan (7) and a set of sieves (8), and a drive mechanism configured to drive a longitudinal reciprocating motion of the grain pan (7) and superimpose a lateral reciprocating motion component on the longitudinal reciprocating motion.

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.

The invention provides an adaptive control system and a regulating method for the threshing separation load of the combined harvester and the longitudinal axis. The control system mainly comprises entrainment loss monitoring device, grain breaking rate monitoring device, device for regulating clearance of cutting concave outlet, jitter board load monitoring device, return plate load monitoring device and on-line monitoring and control system. According to the differential signal of the impact force sensor and the inertial force sensor, the cutting flow threshing and separating device is calculated by real-time monitoring of the grain breaking rate, the entrainment loss rate, the tangential groove outlet gap, the cutting drum speed and the longitudinal axis drum speed. And the ratio of the threshing separation load of the cut-off threshing separator and the longitudinal-axial-flow threshing and separating device is adjusted at a reasonable ratio range, to meet the difficult to take off, easy to off and other crops of different harvest requirements, to maintain the best threshing capacity and better adaptability.

A combine including a chassis, a crop residue handling system including a residue chopper, residue spreader, a spreader chute and a swath selection door, a receiver configured to determine a location of the combine, and a controller that controls the residue handling system. The controller configured to determine the location of the combine on a map, execute a crop residue spreading mode in response to the controller determining that the location of the combine is located in a designated crop residue spreading zone indicated on the map, and execute a crop residue windrow mode in response to the controller determining that the location of the combine is located in a designated crop residue windrow zone indicated on the map.

A combine harvester fan housing assembly may include a fan enclosure formed as a single unitary body out of a polymeric material. The fan enclosure may include a spiral duct spiraling about an axis, a first axial inlet opening sized to axially receive a fan therethrough and a second axial inlet opening and a discharge duct extending from the spiral duct. The combine harvester fan housing assembly may further include an inlet ring releasably mounted to the fan enclosure about the first axial opening, the inlet ring projecting into the first axial opening by an extent so as to extend radially inward of blade ends of the fan.

A combine harvester includes threshing apparatus, separating apparatus, a grain cleaning system located downstream of the separating apparatus, and a material conveyance system arranged to convey crop material from the separating apparatus to the grain cleaning system. The grain cleaning system includes screening apparatus, a fan arranged to generate a cleaning airstream through the screening apparatus, and a fan control system configured to control a fan speed. The fan control system includes a proximity sensor mounted above the material conveyance system for sensing a material volume. The fan control system controls the fan speed in dependence upon the material volume.

A grain cleaning system in a combine harvester including a frame, a chaffer sieve, and a lower sieve. A clean grain chute is located under the lower sieve to catch grain falling therefrom and is inclined to direct the caught grain to a clean grain trough. A tailings return chute is disposed under the clean grain chute and is configured to direct tailings to a tailings collection trough. A multi-configurable plate is mounted to the frame and positioned under a rear portion of the chaffer sieve. The plate is moveable between different operating positions. In a first operating position the plate is configured to guide material incident thereon to the tailings return chute. In a second operating position the plate is configured to guide material incident thereon to the clean grain chute.
