A clean grain conveyor for an agricultural combine () includes an auger conveyor () and a paddle elevator () that are connected by a transition tube () having a triangular aperture.

Clean grain conveyor for an agricultural combine

A straw chopper for an agricultural harvesting machine includes a housing, a rotor carried by the housing, and a stationary knife bank. The rotor includes a plurality of pendulously mounted knife blades. The stationary knife bank includes a plurality of stationary knife blades adjustably movable toward and away from the rotor. The stationary knife bank includes a tension rod extending longitudinally through the stationary knife bank and having a threaded end, and at least one wing nut threadingly engaged with the threaded end.

Straw chopper for combine with adjustable stationary knife bank

A beater for an agricultural combine comprises an open rotor frame mounted on a drive shaft. The open frame defines a cylindrical periphery to which are mounted transversely extending mounting plates. Adjacent mounting plates define mounting channels. Replaceable crop-engaging blades are mounted in the mounting channels. The mounting plates are provided with a first upturned portion and a second upturned portion. Each replaceable blade is provided with a crop engaging portion and an integral mounting portion. The crop engaging portion of the replaceable blades is provided with first and second mounting lips. The first and second mounting lips respectively engage first and second edges on the first and second upturned portions to prevent rotation of the replaceable blade. The crop engaging portion of the replaceable blade extends outwardly from the mounting channel to engage the crop. Open gaps in the mounting channel are formed between adjacent replaceable blades.

Agricultural beater having replaceable blades

The discharge section of an axially arranged rotary combine is provided with a metering edge overhanging a discharge chute. The metering edge is asymmetrical having a downswept edge and an upswept edge. The downswept edge is more open that the upswept edge. The downswept edge opens continually until the bottom dead center of the metering edge. The upswept edge closes continually form the bottom dead center of the metering edge. The downswept edge opens more slowly than the upswept edge closes

Metering edge for axially arranged rotary separator

The discharge section of an axially arranged rotary combine is provided with a discharge chute having a ramp on the downward swept side. The ramp is provided with upper and lower metering edges for metering the flow of crop material other than grain from the helical flow to a transverse discharge beater. The floor of the discharge chute is provided with three guide vanes that define specific flow paths of the crop material being expelled by the axial crop processing unit and directing this crop material uniformly across the transverse discharge beater. The upward swept side of the discharge chute is provided with a filler plate for engaging crop material that was not engaged by the vanes to direct this crop material to the upward swept side of the discharge beater.

Discharge geometry for axially arranged rotary separator

The invention is directed to a beater for a combine having a hollow drum having a triangular cross section with first, second and third apexes that define the first, second and third wings of the beater. Identical first, second and third members are mounted to the triangular drum at the apexes. Each of the members have upturned ends that are joined together to form fourth, fifth and sixth apexes which define the fourth, fifth and sixth wings of the beater.

Beater for an agricultural machine

An axial flow agricultural combine has a single element rotor defining a rotor axis. The rotor is housed in a rotor housing having a threshing section and a separating section. The threshing section of the rotor housing defines a threshing axis and the separating section of the rotor housing defines a separating axis. The threshing section of the rotor housing is substantially concentric with the rotor axis passing through that section. The separating section of the rotor housing is arranged eccentric to the rotor axis. The separating axis is located above the rotor axis.

An axial agricultural combine having independently driven threshing and separating sections. A midpoint support bearing is located between the threshing and separating sections of the rotor. The midpoint support bearing is provided with a saddle mounted to the sidesheets of the combine and extending across the bottom portion of the rotor housing. A sealing disc is mounted to the saddle and has a sealing ring that covers the threshing section/separating section interface and a web that is provided with a bearing assembly. The drive shaft for driving the threshing section passes through this bearing.

An improved infeed plate more evenly distributes harvested crop material as it is transferred from a feederhouse to an axial rotor. Crop on one side of the infeed plate is curled into the bottom of the rotor by a conical section. Crop on the other side of the rotor is introduced to the top of the rotor by a ramp. Crop in the middle section is directed to the bottom of the rotor. The ramp section is provided with an upwardly extending rim.
