Abstract:
A method for producing seed corn from the corn plants, for use in growing subsequent corn plants, includes measuring a moisture content of corn kernels on ears of the corn plants in the field and removing, by a combine harvester, the ears of corn from the corn plants when the moisture content satisfies a threshold moisture content. The method then includes separating the corn kernels from cobs of the ears of corn onboard the combine harvester and collecting the separated corn kernels for use as seed corn, whereby one or more subsequent corn plants can be grown from the collected corn kernels.
Abstract:
Steps to manufacturing a feed beater for a twin axial-flow crop processor in a combine harvester including cutting a flat state vane element from sheet material and bending along predetermined bend lines before being secured to a rotor core. The vane element includes a transverse vane section parallel to the rotation axis, and a directional vane section having an effective edge that extends at a non-zero angle to the rotation axis.
Abstract:
An agricultural harvester includes a chassis and a threshing and separating system carried by the chassis that is configured for threshing and separating grain from gathered crop material. The threshing and separating system includes: a rotor defining a longitudinal axis; a concave at least partially surrounding the rotor; a transition cone defining an infeed to the rotor; and a transition surface connecting the transition cone to the concave and having a conical portion defined about the longitudinal axis and a blended portion connected to the conical portion. The blended portion defines a first end connected to the conical portion and a second end distanced from the first end in a lateral direction. The blended portion defines a substantially conical shape about the longitudinal axis at the first end and approaches a substantially cylindrical shape about the longitudinal axis toward the second end.
Abstract:
A feeder for a combine harvester. The feeder includes a housing and a conveyor assembly mounted in the housing. The conveyor assembly includes a frame having lateral support arms, and moveable belts guided by sprocket wheels. The sprocket wheels are mounted on a drive shaft proximate an outlet section of the housing and on a conveyor shaft proximate an inlet section of the housing. The sprocket wheels are mounted on a drive shaft proximate an outlet section of the housing and on a conveyor shaft proximate an inlet section. The conveyor assembly is equipped with a first and second tensioning mechanism, the first mechanism being configured to push the conveyor shaft forward with respect to the frame, the second mechanism including spring-operated tensioning arms and tensioning rolls mounted above the support arms.
Abstract:
A feederhouse for attaching a header to an agricultural combine has a sill plate that supports a support beam of the header during operation of the header. A mounting hook with a hooked end is supported for forward and rearward movement with respect to the sill plate. A locking pin is configured to lock the mounting hook at either of a first position and a second position with respect to the sill plate. When the support beam is supported by the sill plate and the mounting hook is locked in the first position, the header is disposed at a first angle with respect to the feederhouse. When the support beam is supported by the sill plate and the mounting hook is locked in the second position, the header is disposed at a second angle with respect to the feederhouse.
Abstract:
A feederhouse (20) for a combine harvester (10) comprises an endless conveyor having at least two traction means (82) made of inherently flexible material circulating about the deflection rollers (78, 80) and offset from one another in the axial direction of the deflection rollers (78, 80), between which traction means conveying strips (84) extend. The inner sides of the traction means (82) are furnished with cams (34, 36) made of inherently flexible material.
Abstract:
An inclined conveyor for a combine harvester has two drive elements which define a conveying direction and revolve in a conveying duct. Conveying duct is divided into an overshot return duct and an undershot conveying duct by a separating element situated between the upper run and the lower run of the drive element. Drive element is interconnected by carriers situated transversely with respect to conveying direction that convey harvested crop in undershot conveying duct. The difference in speed between the carrier bars and harvested crop stream is eliminated, and at least reduced, by additional acceleration of harvested crop stream. Carrier bars serve as carriers, and as acceleration elements for the harvested crop. That is because the cross section of each of the carrier bars viewed in conveying direction, occupies at least 30% of the smallest internal cross section of undershot conveying duct.
Abstract:
A beater (17) for use in a combine harvester in which harvested crop is fed as a number of separate streams towards a threshing and/or separating rotor (21) which rotates within a housing (20) about an axis disposed generally longitudinally relative to the combine. The beater rotates about an axis generally transverse relative to the combine and is divided asymmetrically along its length into a number of sections (A1, B1,C1) corresponding to the number of streams of crop, each section of the beater having differently angled crop feeding members (17a,17b,17c) which direct crop towards a crop steam.
Abstract:
A feeder drum for a self-propelled combine harvester has a feeder drum element, and a plurality of feeder aids associated with the feeder drum element and having effective surfaces which are wedge-shaped and tapered.
Abstract:
The extension has an elongate blade shape and is positionable in radially outwardly extending relation along a leading edge of a rotor inlet flight, the blade having a leading edge located forwardly of the leading edge of the flight so as to rotate in advance thereof. The leading edge preferably has a curved, swept back shape relative to the rotational direction, which gradually increases in slope in the radial outward direction, so as to facilitate smooth acceleration of the crop material in the radial outward direction. The extension has a rearwardly facing blade or crop flow surface oriented at an angle of attack less than the angle of attack of the associated flight, so as to be less blunt and to facilitate smooth crop material flow onto the flight. The extension shape generates a rearwardly directed air flow when rotated.
