Abstract: A sieve assembly for use within an agricultural harvester may generally include a sieve, a crop material sheet, and at least one support element. The sieve extends along a length defined between a first sieve end and a second sieve end and processes a flow of harvested crop material. The sieve also defines a plurality of openings through which cleaned crop material of the flow of crop material is directed. The crop material sheet extends along a length defined between a first sheet end and a second sheet end and receives the cleaned crop material directed through the sieve's openings. The crop material sheet then directs the flow of cleaned crop material towards a separate component of the crop processing system. In addition, the support element(s) is directly coupled between the sieve and the crop material sheet and structurally connects the sieve to the crop material sheet.

Abstract: An agricultural vehicle including at least one threshing rotor and an auger bed located underneath the at least one threshing rotor. The auger bed has a working position and a cleaning position. The auger bed includes a frame, a plurality of augers rotatably coupled to and supported by the frame, and a trough portion moveably connected to the frame. In the working position the bottom surface of the trough portion is positioned underneath the plurality of augers and in the cleaning position the entire trough portion is moved relative to the frame so that the bottom surface of the trough portion is not positioned underneath at least a portion of the plurality of augers, creating an open space underneath the portion of the plurality of augers for allowing an unwanted material to pass therethrough.

Abstract: An apparatus and method for distributing crop material onto a cleaning sieve of an agricultural combine. The method includes providing a sensor in connection with a controller, the sensor senses information representative of grain associated with a crop material distributor and an inclination angle associated with the crop material distributor, and outputs signals representative of grain associated with a crop material distributor and an inclination angle associated with the crop material distributor to the controller. The method provides the crop material distributor for distributing crop material from a threshing system onto a sieve. The controller determines information representative of grain associated with a crop material distributor and an inclination angle associated with at least one of the crop material distributor and the combine. The method includes outputting signals for operable control of operating parameters associated with the crop material distributor and the sieve.

Abstract: An agricultural harvester includes a grain processing section having a sieve. The sieve is driven in fore and aft oscillation while permitting side to side movement by a pair of cast members interconnected each having three mounting points. Two of the mounting points of the members are interconnected by flexible rubber bushings and the third mounting point of one of the members receives fore and aft oscillating movement and the third mounting point on the second of the members pivotally interconnects to the sieve to drive it into fore and aft oscillation while permitting side to side movement.

The crop material handling assembly is driven in fore and aft oscillation by a device while permitting side to side movement.

Abstract: A tailings conveyance including a housing having a front plate, a back plate, and a wall, and is adapted to recycle tailings through a cleaning system of a combine using at least one impeller. The wall of the housing describes an arc near the impeller paddles over a segment of a circle described by the circumference of the impeller. The wall further continues on a tangent away from the circle at a point of tangency. A sensor is positioned proximate to the point of tangency, and senses whether a space between the front plate and the back plate directly adjacent to the sensor is obscured by tailings as the impeller rotates. A controller or control system connected to the sensor calculates an amount or percentage of time the space between the front plate and the back plate directly adjacent to the sensor is obscured by tailings as the impeller rotates.
