A header for an agricultural machine having a cutterbar, an auger and a rotatable reel, the reel having a main axis of rotation around which the reel is rotated in one direction, crop-engaging members being rotatably mounted on the reel around respective pivot axes disposed around the main shaft, is disclosed wherein inclination control means including steering means positioned eccentrically of the main axis are operable, during rotation of the reel in said one direction, to rotate the crop-engaging members around the respective pivot axes in the opposite direction so as to maintain the crop-engaging members at a fixed positional inclination relative to the horizontal so that the free ends of the crop-engaging members define a circularly shaped locus. Drive means are associated with the steering means for oscillating said steering means during rotation of the reel such that the crop-engaging members equally are oscillated back-and-forth around their respective further pivot axes on the reel and the locus defined by the path of movement of the free ends of the crop-engaging members deviates from said circular shape. Means are also provided for neutralizing said drive means associated with the steering means so that the reel may be operated with either a circular or a non-circular locus.

A round baler includes an endless flexible member which has an inner course that expands around and contacts at least a portion of a bale during formation thereof. The endless flexible member extends around a plurality of drive and guide members, all of which are disposed within the envelope defined by the endless flexible member. When the bale has reached its maximum size, the inner course of the endless flexible member is engaged with all of the drive and guide members so that the inner course cannot expand any further and thereby assumes a generally fixed position.

Round baler with expanding bale chamber

A round baler includes front and rear expandable members arranged to form a vertically oriented start chamber which expands to a cylindrical shape during bale formation. An arm which supports the front expandable member is pivotally mounted and carries guide members at its ends around which the front expandable member passes. Upper and lower T-shaped supports which support the rear expandable member are pivotally mounted, and each T-shaped support carries a pair of guide members for engaging the rear expandable member.

An infeed mechanism for a rotary cleaning device for cleaning threshed grain in combine harvesters is disclosed wherein an infeed auger includes a pair of helical flights terminating in a pair of radially extending distributing paddles. The infeed auger is mounted forwardly of a rotatable cleaning cylinder with the distributing paddles being positioned within the axial opening through the cleaning cylinder to discharge threshed grain radially outwardly into individual cleaning shoes. A grain pan is provided within each cleaning shoe to receive the threshed grain discharged from the distributing paddles, each cleaning shoe being operable to reciprocatably move in a generally fore-and-aft direction to convey grain received on the grain pans rearwardly onto sieves also mounted within the cleaning shoes. The infeed mechanism is also provided with an upwardly extending infeed chute that is flared outwardly from top to bottom to serve as a conduit for the infeed of threshed grain into the infeed auger.

Infeed mechanism for rotary cleaning device in combines

A rotary cleaning mechanism for a combine harvester is disclosed wherein threshed grain is cleaned within a rotatable cleaning cylinder having sieves mounted in a plurality of elongated cleaning shoes disposed around the circumference of the cleaning cylinder to clean the threshed grain through the use of centrifugal forces generated by the rotation of the cleaning cylinder. The cleaning shoes are disposed generally parallel to the axis of rotation of the cleaning cylinder and are reciprocatable in a fore-and-aft direction slightly inclined inwardly toward the axis of rotation to move the grain rearwardly along the sieves. An infeed mechanism for distributing threshed grain onto the cleaning cylinder and a fan for creating a flow of air to clean the grain are also provided.

Rotary cleaning mechanism for combines

A rotary cleaning mechanism for cleaning threshed grain in a combine harvester is disclosed wherein a fan is mounted forwardly of the cleaning cylinder to blow air through the cleaning sieves to make unwanted residue airborne for discharge from the cleaning cylinder. A fan housing is provided with a first passageway to direct a flow of air through the grain being conveyed from a centrally located infeed mechanism onto a radially outwardly spaced grain pan. A second passageway is also provided in the fan housing to direct a flow of air through threshed grain being conveyed rearwardly off the grain pan onto a radially outwardly located cleaning sieve. The fan is mounted on an axis of rotation common with the cleaning cylinder and forwardly of the infeed housing, which includes an eliptically shaped infeed chute to aerodynamically permit the flow of air therearound to clean threshed grain on the cleaning cylinder immediately adjacent thereto. Deflector plates are provided within the second passageway to distribute the flow of air along the axial length of the cleaning cylinder, with a more concentrated flow of air being directed at the forward end thereof.

Fan for rotary cleaning mechanism in combine harvesters

A method for cleaning threshed grain in a combine harvester is disclosed wherein the threshed grain is conveyed into a cleaning cylinder that is rotatably driven at a sufficient speed to impart centrifugal forces on the threshed grain to urge the grain through sieve openings during each entire 360 degree revolution of the cleaning cylinder. The cleaning sieves are mounted within axially extending cleaning shoes connected to the rotating cleaning cylinder for individual reciprocatory movement along a generally axial direction inclined inwardly toward the axis of rotation to convey the threshed grain rearwardly and help the cleaned grain pass through the sieve openings. Simultaneously with the rotating of the cleaning cylinder and the reciprocating of the cleaning shoes, a fan blows air through the sieves in the cleaning cylinder to make the unwanted residue airborne for discharge rearwardly from the cylinder, the air also being directed through the threshold grain twice before it is received on the sieves. Unthreshed heads are received within a tailings section for return to the threshing and separating mechanism for further harvesting treatment before being discharged from the cleaning cylinder.

Method of cleaning threshed grain in a combine

A drive mechanism for rotatably powering a rotary cleaning device for cleaning threshed grain in a combine harvester is disclosed wherein a cleaning cylinder, an infeed mechanism, a fan, and an impeller are rotatable about a common axis of rotation defined by a composite drive shaft that includes a first shaft member having a tubular portion and a second shaft member rotatably received within the tubular portion for rotation independently of the first shaft member. Pulleys keyed to the first and second shaft members rotatably drive the infeed mechanism and the impeller. The fan and the cleaning cylinder are driven by pulleys rotatably mounted on the composite shaft for rotation independently thereof, thereby permitting each component to be driven at different rotational speeds. A mechanism for reciprocatably moving the cleaning shoes during rotation of the cleaning cylinder is also operatively powered by the rotation of the composite drive shaft.
