摘要： A foldable corn head having separable, matable auger sections which are cantilever suspended from the ends thereof to provide an obstruction-free path for harvested ears of corn being transported by the auger. Outer sections of the corn head are foldable vertically about horizontal hinges to reduce the width of the head for over-the-road travel. Stub auger sections are cantilever mounted from end plates in the pivotable outer corn head sections, at least one of the stub sections being driven by an actuator, such as a hydraulic motor means. The stub sections are provided with coupling elements at their inner ends which are matable with coupling elements in the ends of the main auger section. The elements have non-symmetrically disposed mating pins and bores to form the couplings and to align the ends of the helical auger flanges. In a preferred embodiment, the main auger section is supported and driven solely by coupling to the stub sections in harvesting position, and lies free in the trough when uncoupled in non-harvesting position. In a second embodiment, the main auger section is supported at its center by a strut and bearings and is cantilevered outward therefrom to mate with the cantilevered auger stub sections. In all embodiments, the auger flow path for the corn ears is free of auger support elements which can cause plugging of the auger and damage to corn ears, particularly ears of fresh corn for direct retail sale or processing.

摘要： A latch (48) for securing a pivotable portion (34) of a foldable corn head (10) to a fixed portion (32) thereof, the latch being actuated to close or open by the folding action of the corn head portions. In closing the latch, a slidable pin actuator (50) on one of the frame portions, which extends beyond the frame is engaged by the other frame portion. The motion of the pin rotates a crank (56) connected by a connecting link (64 to a rotatable overcenter catch (62) extending through a slot (69) in the other frame portion. The crank rotation causes the catch to rotate to engage and secure the other frame portion on its rear surface (70). Opening of the latch is the reverse of closing. Preferably, the lengths of the crank arms (58 & 60), connecting link, catch shaft (67), and the angles therebetween are selected such that the motion of the catch mimics in synchrony the motion of the pin.

摘要： Parallelogram linkage apparatus for slidably shifting stripper plates in a corn head of a corn harvesting machine to widen or narrow the gap between opposed plates in a row harvester. Each slidable stripper plate has a parallelogram linkage which slidably connects the plate to a supporting frame. The linkage includes two bell cranks pivotably mounted in spaced apart relationship on the frame and connected by an interconnecting arm and having an actuation shaft extending upward from a lobe of each bell crank to engage motion-transforming members at the stripper plate for transforming the arcuate motion of the bell cranks into linear motion of the stripper plate. The upper ends of the actuation shafts are guided in guide elements at the stripper plate elongated in the direction parallel to an edge of the stripper plate. In a preferred embodiment, the actuation shafts extend through openings in the stripper plate and are fitted with rollers which are guided between parallel flanges on the upper surface of the stripper plate. The parallelogram linkages of opposed stripper plates are pivotably connected to a common drag link by primary and secondary connecting levers, respectively, so that opposed plates in each row harvester are moved in opposite directions. Linkage to a common drag link permits all the plate gaps in a multiple row harvester corn head to be changed simultaneously and identically.
