A cleaning fan on an agricultural harvester generates airflow along an airflow path through a fan duct. A movable flap is mounted relative to the fan duct and controlled to divert the airflow path in a side-to-side transverse direction relative to a front-to-back longitudinal axis of the agricultural harvester.

Disclosed is an articulated harvesting combine of a forward power processing unit (PPU) and a rear grain cart, wherein the PPU carries dual axially mounted engines with oppositely opposed crankshafts with one toward the rear grain cart and the other engine away from the rear grain cart, there being no comingling of flywheel output power flow between the two engines.

The disclosure provided herein is directed to an agricultural products cleaning machine for cleaning agricultural products, such as grains in general, whereby the agricultural products are thrown against a sieve system with curved sieves in the shape of a volute by a grain transport and elevation system or bucket elevator. When thrown, the agricultural products move along as a spiral curtain which collides with the curved surface of the sieve, promoting the separation of agricultural products from impurities. The sieve allows adjustment of the mesh, so that a simple adjustment allows the separation of diverse agricultural products without having to change the sieve to a bigger or smaller mesh

A residue handling system for an agricultural harvester includes a chopper that is positionable within a straw hood of the combine harvester and a seed mill that is mounted directly to the chopper. The chopper has projecting elements for chopping straw within the straw hood as the chopper rotates. The seed mill includes a rotatable rotor that is at least partially positioned within a concave. The rotor and the chopper are connected or unitized so as to rotate together.

Receivers are arranged to detect a corresponding observed phase shift, observed attenuation or other observed signal parameters for its respective microphone. An electronic data processor is adapted to estimate a distribution or quantity of material on the sieve based on the observed phase shift, the observed attenuation or the other observed signal parameters relative to a reference phase shift, a reference attenuation or other reference signal parameter. The operator can be alerted via a user interface if the material on the sieve is unevenly distributed or matches a preestablished distribution profile, or the sieve can be adjusted by an actuator to promote a generally uniform distribution.

A cleaning shoe for a combine harvester, including a frame, a sieve and at least one reciprocating mechanism attached to the sieve for reciprocating the sieve in a forwards and backwards motion and the reciprocating mechanism includes an eccentric drive housing, pivotably mounted to the frame, and arranged to rotate around a pivot point thus changing its angle to the horizontal, and an actuator connected to the eccentric drive housing, which varies the angle to the horizontal of the reciprocating motion of the sieve by varying the angle to the horizontal of the eccentric drive housing.

Adjustable screen comprising scales (1) consisting of teeth (1.1) interspersed with bases (1.2), an inclined tab (1.3) on the rear portion and a channel (1.4) between the inclined tab (1.3) and teeth (1.1) for the introduction of the shafts (3.1) for moving the scales, the teeth (1.1) being fluted and the bases (1.2) being flat. It also comprises partitions (2.1) fastened at the ends (2.2) between the sides (2.3) of the structure of the screen (2) and a mechanism for adjusting the scales (3) made up of shafts (3.1) rotating in orifices (2.6) of the sides (2.3) of the structure of the screen (2). After the orifices (2.6), the shafts (3.1) have an S-shaped bend (3.2) for introduction into the orifices (3.4) of the ruler (3.3) in the outer face of the side of the screen (2.3). The end (2.2) has an orifice (2.7) on which a spindle (3.5) with a rotating lever (3.6) is mounted. An elastic part (3.8) flanked by protective elements (3.7) is mounted on the spindle (3.5).

A sieve for use in an agricultural harvester includes a framework with a pair of opposed side members, and a first cross member extending between the side members at one end of the side members. A plurality of louvres extend between the pair of opposed side members. A pair of adjustment laths are respectively associated with and movable generally parallel to the side members, with each of the adjustment laths also being connected with the plurality of louvres. The sieve has an adjustment arrangement positioned below the plurality of louvres. The adjustment arrangement includes an actuator and a frame. One end of the actuator is connected to the first cross member and the other end of the actuator is connected to the frame. The frame has a pair of outboard ends with each of the outboard ends being connected to a respective one of the adjustment laths.
