Definitions
- the present invention relates to agricultural harvesters, and, more specifically to augers in grain headers of harvesters.
- a combine An agricultural harvester known as a "combine” is historically termed such because it combines multiple harvesting functions with a single harvesting unit, such as picking, threshing, separating and cleaning.
- a combine includes a header which removes the crop from a field, and a feeder housing which transports the crop matter into a threshing rotor.
- the threshing rotor rotates within a perforated housing, which may be in the form of adjustable concaves and performs a threshing operation on the crop to remove the grain.
- a perforated housing which may be in the form of adjustable concaves and performs a threshing operation on the crop to remove the grain.
- a cleaning fan blows air through the sieves to discharge chaff and other debris toward the rear of the combine.
- Non-grain crop material such as straw from the threshing section proceeds through a residue system, which may utilize a straw chopper to process the non-grain material and direct it out the rear of the combine.
- a residue system which may utilize a straw chopper to process the non-grain material and direct it out the rear of the combine.
- the combine When the grain tank becomes full, the combine is positioned adjacent a vehicle into which the grain is to be unloaded, such as a semi-trailer, gravity box, straight truck, or the like; and an unloading system on the combine is actuated to transfer the grain into the vehicle.
- a rotary threshing or separating system includes one or more rotors which can extend axially (front to rear) or transversely within the body of the combine, and which are partially or fully surrounded by a perforated concave.
- the crop material is threshed and separated by the rotation of the rotor within the concave.
- Coarser non-grain crop material such as stalks and leaves are transported to the rear of the combine and discharged back to the field.
- the separated grain, together with some finer non-grain crop material such as chaff, dust, straw, and other crop residue are discharged through the concaves and fall onto a grain pan where they are transported to a cleaning system.
- the grain and finer non- grain crop material may also fall directly onto the cleaning system itself.
- a cleaning system further separates the grain from non-grain crop material, and typically includes a fan directing an airflow stream upwardly and rearwardly through vertically arranged sieves which oscillate in a fore and aft manner.
- the airflow stream lifts and carries the lighter non-grain crop material towards the rear end of the combine for discharge to the field.
- Grain and non-grain crop material remaining on the upper and lower sieves are physically separated by the reciprocating action of the sieves as the material moves rearwardly. Any grain and/or non-grain crop material remaining on the top surface of the upper sieve are discharged at the rear of the combine. Grain falling through the lower sieve lands on a bottom pan of the cleaning system, where it is conveyed forwardly toward a clean grain auger.
- the clean grain auger conveys the grain to a grain tank for temporary storage.
- the grain accumulates to the point where the grain tank is full and is discharged to an adjacent vehicle such as a semi trailer, gravity box, straight truck or the like by an unloading system on the combine that is actuated to transfer grain into the vehicle.
- the crop gathering capability of the combine is directly dependent upon the width of the header, since the width defines that amount of crop that the combine encounters as the combine moves forward across a field. Ground contours vary which can lead to some crops being lower than the cutter bar and hence lost grain.
- the present invention provides for the transfer of power through a hinged auger.
- the invention in one form is directed to an agricultural harvester including a chassis, a header for cutting and gathering crop material, the header being carried by the chassis, and an auger.
- the auger moves the cut crop material toward a central area of the header.
- the auger is rotatably carried by the header.
- the auger has a plurality of auger sections.
- the auger includes an auger crankshaft and a hingeable coupling for coupling two of the auger sections to each other.
- the hingeable coupling allows the auger sections to rotate about differing axes.
- the hingeable coupling has an internal opening.
- the auger crankshaft provides positional timing to auger fingers.
- the auger crankshaft passing through the internal opening.
- An advantage of the present invention is that the positioning of auger fingers is controlled by the crankshaft positioning while rotational power is transferable through the hinged coupling of the auger in the header.

- an agricultural harvester in the form of a combine 10, which generally includes a chassis 12, ground engaging wheels 14 and 16, a header 18, a feeder housing 20, an operator cab 22, a threshing and separating system 24, a cleaning system 26, a grain tank 28, and an unloading conveyance 30.
- Unloading conveyor 30 is illustrated as an unloading auger, but can also be configured as a belt conveyor, chain elevator, etc.
- the front wheels 14 are larger flotation type wheels, and the rear wheels 16 are smaller steerable wheels.
- Motive force is selectively applied to the front wheels 14 through a power plant in the form of a diesel engine 32 and a transmission (not shown).
- a power plant in the form of a diesel engine 32 and a transmission (not shown).
- the combine 10 is shown as including wheels, is also to be understood that the combine 10 may include tracks, such as full tracks or half tracks.
- the header 18 is mounted to the front of the combine 10 and includes a cutter bar 34 for severing crops from a field during forward motion of the combine 10.
- a rotatable reel 36 feeds the crop into the header 18, and an auger 38 feeds the severed crop laterally inwardly from each side toward the feeder housing 20.
- the feeder housing 20 conveys the cut crop to the threshing and separating system 24, and is selectively vertically movable using
- actuators such as hydraulic cylinders (not shown).
- the threshing and separating system 24 is of the axial- flow type, and generally includes a rotor 40 at least partially enclosed by and rotatable within a corresponding perforated concave 42.
- the cut crops are threshed and separated by the rotation of the rotor 40 within the concave 42, and larger elements, such as stalks, leaves and the like are discharged from the rear of the combine 10.
- the threshing and separating system 24 is illustrated as being of an axial- flow type having a rotor, it is also contemplated to use the present invention with other conventional threshing systems.
- the cleaning system 26 may include an optional pre-cleaning sieve 46, an upper sieve 48 (also known as a chaffer sieve), a lower sieve 50 (also known as a cleaning sieve), and a cleaning fan 52. Grain on the sieves 46, 48 and 50 is subjected to a cleaning action by the fan 52 which provides an airflow through the sieves to remove chaff and other impurities such as dust from the grain by making this material airborne for discharge from the straw hood 54 of the combine 10.
- the grain pan 44 and the pre-cleaning sieve 46 oscillate in a fore-to-aft manner to transport the grain and finer non-grain crop material to the upper surface of the upper sieve 48.
- the upper sieve 48 and the lower sieve 50 are vertically arranged relative to each other, and likewise oscillate in a fore- to-aft manner to spread the grain across the sieves 48, 50, while permitting the passage of cleaned grain by gravity through the openings of the sieves 48, 50.
- Clean grain falls to a clean grain auger 56 positioned crosswise below and in front of the lower sieve 50.
- the clean grain auger 56 receives clean grain from each sieve 48, 50 and from the bottom pan 58 of the cleaning system 26.
- the clean grain auger 56 conveys the clean grain laterally to a generally vertically arranged grain elevator 60 for transport to the grain tank 28.
- Tailings from the cleaning system 26 fall to a tailings auger trough 62.
- the tailings are transported via the tailings auger 64 and the return auger 66 to the upstream end of the cleaning system 26 for repeated cleaning action.
- the cross augers 68 at the bottom of the grain tank 28 convey the clean grain within the grain tank 28 to the unloading auger 30 for discharge from the combine 10.
- the non-grain crop material proceeds through a residue handling system 70.
- the residue handling system 70 may include a chopper, counter knives, a windrow door and a residue spreader.
- FIG. 2 there is shown and illustrated the header 18 with a portion of the auger 38 shown and with some elements omitted for the sake of clarity.
- the auger 38 has three sections shown, denoted here as 38 A, 38B and 38C, which is
- Sections 38C and 38B are rotatably coupled together with a hanger support 72.
- the hanger support 72 is fixed to the header 18 and provides support to the auger 38 so that the auger 38 can rotate suspended above the lower structure of the header 18.
- Auger sections 38A and 38B are coupled together by way of a flexible coupling 74, also known as a hingeable coupling 74, which allows the auger section 38A to rotate about an axis that can angularly vary from an axis about which auger sections 38B and 38C rotate. As shown auger sections 38B and 38C are coupled so that they rotate about the same axis.
- the hingeable coupling 74 allows for the flexure of the auger 38, which may proximally correspond to the location of hinged portions of the header 18. This is particularly
- the header 18 is long, say over 40 feet in width.
- FIG. 3 there is shown a view of the hingeable coupling 74, and an aspect of the present invention, having an opening 76 that exists through the various components of the hingeable coupling 74, as discussed later.
- An auger crankshaft 78 passes through the opening 76 and does not touch the hingeable coupling 74.
- the auger crankshaft 78 provides rotational movement to effect the timing of auger fingers that extend through sections of the auger 38, and may additionally provide movement to other
- the auger crankshaft 78 has a separate hingeable coupling 80 (illustrated in Fig. 6), which is spaced apart from the hingeable coupling 74 of the auger 38, as shown. It is also contemplated that the hingeable coupling 80 and the hingeable coupling 74 may be collocational, or generally close to each other.
- the opening 76 is shown as having different sizes in the various components, and it is also contemplated that the opening sizes may all be the same. Openings 76 have edges 82, which are not touched by the auger crankshaft 78 as the auger 38 hinges about the hingeable coupling 74.
- the hingeable coupling 74 includes auger couplings 84 and 86, winged couplings 88 and 90 and an inner coupling 92.
- the auger couplings 84 and 86 are respectively coupled to the auger sections 38A and 38B.
- Winged couplings 88 and 90 are respectively coupled to the auger couplings 84 and 86, and are both pivotally coupled to the inner coupling 92.
- the pivotal couplings are substantially
- the auger crankshaft 78 can also have a hingeable coupling 80, as illustrated in Fig. 6.
- the positioning of the hingeable coupling 74 may be proximate to the hanger support 72 and one portion of the hingeable coupling 74 may be rotationally coupled to the hanger support 72. It is contemplated that the positioning of the hingeable coupling 80 may be close, or even collocational, to the hingeable coupling 74, as shown in Fig. 6 and the opening 76 is sized so that the edges 82 are not touched by the crankshaft 78 even though couplings 74 and 80 are not in contact and hinge at different points along the longitudinal axis of the auger 38 as the hingeable coupling 74 is fully flexed.
- the hingeable coupling 74 is entirely interior to the auger 38.
- the present invention couples at least some of the adjacent sections of the auger 38 together allowing a hinging of the auger 38 over the length of the header 18 to thereby allow for extended lengths of the auger 38 to operate as the header 18 is articulated or allowed to flex over non-planar ground.
- One aspect of the present invention that allows the hinged coupling 74 to work is the passing of the auger crankshaft 78 through the coupling to thereby allow for a positioning of the auger fingers as the auger 38 rotates.
- Auger crankshaft 78 can be rotated to alter the timing of the auger fingers along the length of the auger 38.
- the improvement allows for closer ground contour following of the header 18 and the
- varifeed headers can be made to extended lengths, such as greater than 41 feet using the present invention.
- the present invention uses a large cross coupling 74 so that the auger tube 38 can flex. Yet there is a large opening 76 in the middle of the coupling 74 to allow the auger crankshaft 78 to pass therethrough, all to allow the auger 38 the ability to flex a few degrees.
- the flexing or hinging allows for the transfer of auger torque and the timing of the auger fingers to be preserved.
