The present application 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 device includes a cylinder (1) that has a larger diameter zone (2) and smaller diameter zone (3), the 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).

A separator module for an agricultural machine. The separator module includes a feederhouse configured to receive crop from a harvesting platform, a casing enclosing a rotor positioned therein and rotatable relative to the casing for processing crop from the feederhouse, a cover extending between the feederhouse and the casing, and a noise control treatment coupled to the cover.

An arrangement for switching over a combine harvester between swath deposit operation and wide distribution operation comprises a front element and a rear element which follows downstream. The rear element may be attached in an articulated fashion, in an inherently rigid fashion, at its upstream end about a first pivoting axis and may be moved between a swath deposit position and a wide distribution position by an adjustment drive. The front element may be attached in an articulated fashion at its upstream end about a second pivoting axis, may be inherently rigid and may also be coupled to the adjustment drive.

A method for controlling crop material speed through a rotor/cage assembly of an agricultural combine. The method includes the steps of monitoring a grain loss of the combine and adjusting an orientation of a vane coupled to the cage responsive to the grain loss, a cleaning system load and/or a straw length.

A separator arrangement has an inlet head housing, a feed drum and two axial separating rotors projecting by one end portionwise into the inlet head housing. The inlet head housing has planar inlet portions which extend over the width of the respective axial separating rotor and between which is arranged a ramp-shaped housing portion extending paraxial to the conveying direction of the axial separating rotors and which assists in dividing a harvested material flow into partial flows to be fed to the axial separating rotors. At least one separating element is associated with the ramp-shaped housing portion and has a base body which extends perpendicular to the surface of the housing portion and which has an end face formed as a cutting edge. A coating comprising a wear-resistant second material is arranged on the end face and extends substantially medially in the longitudinal direction of the end face.

A separating and cleaning mechanism for an agricultural combine may include: a return pan. The return pan includes a textured floor, two augers, and two motors coupled to the two augers, respectively, to selectively drive the motors in rotation independently. The textured floor may oscillate in a fore-and-aft direction to move grain toward the two augers.

A method for the operation of a combine harvester includes processing a harvested material flow by at least one axial separator and ejecting a residual material flow formed in this way from the combine harvester by at least two ejection devices. The axial separator is formed by a movable vane element by means of which the residual material flow exiting from the axial separator is distributed on a work member downstream of the axial separator. In order to further improve the distribution of the residual material flow on the field, an actual distribution of the residual material flow on the two ejection devices is detected, wherein, when a deviation of the actual distribution from a predetermined reference distribution is detected, the vane element is readjusted so that the actual distribution is at least approximated to the reference distribution.

The present invention comprises multiple embodiments of an automated, dynamic cover plate system, which may be quickly attached, detached and adjusted to the exterior of a concave grate of a combine harvester in order to adjust the flow characteristics of the concave or separator grate assemblies. The automated, dynamic cover plate system improves the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. The automated, dynamic cover plate system of the present invention is designed to be controlled, either manually or automatically, by the operator of the combine harvester or by a computerized or automated intelligence system.

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).

A rotor and cage assembly includes a skeleton of curved spaced-apart side members affixed to laterally extending upper and lower spaced-apart members therebetween and surrounding the rotor. One of the curved spaced-apart side members is terminated with curved fingers. Three concave inserts insert laterally into the skeleton spanning 270 around the rotor. One of the concave inserts carries straight fingers that interlace between the skeleton side member curved fingers. A control assembly of plates having arcuate slots placed at 3 of the pivots of the skeleton assembly, 3 control bars connected to the skeleton pivots, and an actuator is connected separately to each control bar at one end effect arcuate rotation of the control bars resulting in the synchronized rotation of the arcuate slotted plates so that the interlaced straight fingers move closer together or farther apart with the fixed skeleton assembly curved fingers for different types of grain.
