A threshing and separating system for an agricultural harvester includes a rotor configured to rotate about a rotor axis, a rotor cage at least partially enclosing the rotor and including a tailings return inlet formed therein and configured to couple to a tailings return elevator and an insert opening formed therein that is at least partially circumferentially aligned with the tailings return inlet relative to the rotor axis, at least one concave coupled to the rotor cage and defining a plurality of concave perforations, and a threshing insert removably coupled to the rotor cage and including at least one mounting opening. The threshing insert at least partially covers the insert opening and is positioned such that material from the tailings return inlet travels past the threshing insert before reaching the concave.

A combine harvester comprises a threshing system and a cleaning system. The cleaning system comprises a crop flow sensing system configured to monitor a lateral distribution of crop on the cleaning system. The threshing system comprises a return pan configured to guide the threshed and separated grain in a forward direction towards the cleaning system. The combine harvester further comprises a hillside compensation system, configured to control the cleaning system in order to adjust the lateral distribution of crop on the cleaning system. The hillside compensation system is further configured to control the return pan separately from the cleaning system and depending on the lateral distribution of crop on the cleaning system.

A combine harvester comprising a pair of track units at a front of the harvester. The track units are suspended so that a frame of the units is pivotable about a centrally placed pivot axis, the axis dividing the track units between a front and rear portion. For each of the track units, the harvester comprises at least one variable length actuator mounted between the chassis of the harvester and the frame of the track unit, the actuator being mounted so that it is capable of actuating an upward or downward tilting of the front portion of the track unit. The actuator is operated to counteract an excessive downward or upward tilting of the front portion of the unit. The actuator may be operated by a control mechanism working on the basis of measurements performed by suitable sensor arrangements that monitor or predict the downward or upward tilting.

A threshing system for an agricultural harvester includes a rotor having a proximal end adapted to receive material from a feeding mechanism and a distal end. A discharge housing surrounds the distal end of the rotor. The discharge housing includes a side wall spaced radially apart from the rotor to define a discharge passage between the rotor and the discharge housing. At least one vane is pivotably mounted to the side wall of the discharge housing at a downward swept side of the rotor. The vane extends from the inner surface of the discharge housing. The position of the vane is adjustable to change a trajectory of material expelled from the discharge passage. The vane is positioned on a large diameter portion of the discharge housing in order to limit compression of the material as the material passes along the at least one vane.

The present invention comprises a removable cover plate assembly, 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 cover plate assembly improves the threshing capability of the rasp bar threshing cylinder while simultaneously capturing additional threshed grain. Moreover, the cover plate assembly of the present invention enables a single set of concave grate assemblies to better harvest a wider variety of crop types.

A mobile machine is described. In one example, the machine includes a first subsystem comprising propulsion components configured to propel the mobile machine, a second subsystem, a first drive mechanism, a second drive mechanism, a coupling mechanism, and a controller configured to actuate the coupling mechanism to selectively couple one of the first or second drive mechanisms to drive one or more components of the second subsystem with variable speed and direction.

A threshing system for an agricultural harvester includes a rotor and a substantially cylindrical cage that surrounds at least a portion of the rotor. The threshing system also features a material flow adjustor for controlling axial movement of material through the cage. The material flow adjustor is movably mounted adjacent to a threshing space and includes at least one material conveying edge that enters the threshing space. The material flow adjustor is moveable between a first operative position, in which the at least one material conveying edge is spaced from the rotor in a radial direction by a first distance, and a second operative position in which the at least one material conveying edge is spaced from the rotor in the radial direction by a second distance, the second distance being less than the first distance.

The present invention provides a cutter for corn threshing. The cutter is mounted on a rotary food processor with a driving device, which comprises a cylinder with one open end; a cavity disposed in the cylinder to accommodate threshed corn cobs; a cutting member disposed at the middle of the open end of the cavity; and a locking portion disposed at the other end of the cylinder and connected to the driving device of the rotary food processor in a detachable manner. The present invention further discloses a rotary food processor with this cutter. The cutter for corn threshing and the rotary food processor both have the advantages of small volume, simple operation and high practicability.
