Abstract:
A combine is provided, with a harvested crop processing arrangement with an outlet for straw that is associated with an ejection drum and an endless conveyor arranged between the ejection drum and a straw chopper. In its rear region, the endless conveyor can be pivoted about a horizontal axis extending transverse to the direction of operation between a chopper position and a swath depositing position.
Abstract:
A straw chopper for an agricultural harvesting unit includes a housing, and a rotor carried by the housing. The rotor includes a center chopping section and a pair of fans respectively positioned at longitudinally outboard ends of the center chopping section. Each fan includes a hub rotatable in a direction of rotation, and a plurality of fan blades connected with the hub at a plurality of angularly spaced locations about the hub. Each fan blade has a generally U-shaped portion with a rear wall and a pair of side walls extending from the rear wall in the direction of rotation.
Abstract:
A flexible reel (100) for an agricultural harvesting head (115) includes a plurality of reel sections (102, 104, 106) coupled together with flexible joints (210), wherein bats (206, 218) mounted on one reel section (102, 104, 106) overlap and interleave with the bats (206, 218) of an adjacent reel section (102, 104, 106).
Abstract:
A combine harvester includes a dust suppressor arrangement including an air duct arrangement which is coupled between an enclosed zone, extending rearwardly from the discharge end of the feederhouse and above a transverse crop conveying arrangement, and a cleaner fan arrangement so that the fan arrangement draws dust-laden air through the duct arrangement from the zone and discharges the dust-laden air into the chaffer and sieve arrangement of the crop cleaning arrangement.

Abstract:
A draper platform (100) for an agricultural combine that has a first frame section (104) with a first endless conveyor belt (132, 126) wrapped around a first inner roller (254, 258) and a first outer roller (251), the first outer roller (251) having a first axis of rotation; a second frame section (102, 106) supported on the first frame section (104) having a second endless conveyor belt (124, 130) wrapped around a second inner roller (249) and a second outer roller (251), the second inner roller (249) having a second axis of rotation; a first pivot joint (110, 114) coupling the first frame section (104) to the second frame section (102, 106), such that the second frame section (102, 106) pivots with respect to the first frame section (104) about an axis (108, 112) that extends generally parallel to the first outer roller (251) and the second inner roller (249), and in which the first pivot joint (110, 114) maintains a constant distance between the first outer roller (251), and the second inner roller (249) when the second frame section (102, 106) pivots with respect to the first frame section (104) about the axis (108, 112).
Abstract:
In an axial flow rotary separator, a transition zone between the infeed section and threshing sections is modified to serve as a stone trap or arresting and ejecting device. Radially aligned inner and outer stone collars carried by the separator rotor and casing respectively, obtrude into the annular space between rotor and casing to define between them an annular slot or gate, decreasing or limiting the annular space so as to arrest the downstream passage of stones greater than a predetermined size. The inside surface of the casing immediately upstream of the stone collars is smooth and free of guide vanes to provide a track over which arrested stones may be propelled by conveyor flights of the rotor. A permanently open outlet in the stone track allows the rotor to eject stones tangentially and centrifugally into a stone sump connected to the casing. The stone sump is easily emptied by opening a door accessible from outside the combine body wall.
Abstract:
A crop residue chopping and distributing arrangement has a straw chopper (60) and at least one impeller blower (100) arranged downstream of straw chopper (60), the impeller blower comprising throw paddles (102, 102′) that can be set in rotation about an axis of rotation (108). The throw paddles (102, 102′) extend in the axial direction only over a part of the axial dimension of impeller blower (100). Adjacent throw paddles (102, 102′) that are offset angularly in the circumferential direction are respectively arranged offset in the axial direction.
Abstract:
A draper platform (100) for mounting on the feederhouse of an agricultural combine, comprises a center frame section (104) configured to be supported on the feederhouse and supporting a first endless conveyor belt (132, 126); a wing frame section (102, 106) configured to be supported on a first side of the center frame section (104) and having a second endless conveyor belt (124, 130); and a first pivot joint (110, 114) coupling the center frame section (104) to the wing frame section (102, 106), the first pivot joint (110, 114) constraining the wing frame section (102, 106) to pivot with respect to the center frame section (104) about a generally horizontal and forwardly extending axis (108, 112), the first pivot joint comprising first, second, and third pivot couplings (308, 310, 334), wherein the first pivot coupling is a break-away coupling and is disposed forward of the second pivot coupling (310) and the third pivot coupling (334).
