摘要： A combine feeder slat having a first base, a second base, and a slat body. The bases are located at respective ends of the slat, and have respective upper and lower surfaces. The slat body extends longitudinally and connects the bases. The slat body has a variable profile as viewed along the longitudinal direction, that transitions from a first profile shape at the first base, to an intermediate profile shape between the first base and the second base, to a second profile shape at the second base. The intermediate profile shape includes a front lip, a rear lip, and an upward-facing concave projection that connects the front lip to the rear lip and extends below an attachment plane defined between the first lower surface and the second lower surface. The first base, second base, and slat body are made from a unitary metal part.

摘要： A feederhouse assembly for an agricultural vehicle includes a feederhouse frame including at least four interconnected walls, an open front end, an open rear end, and a hollow space circumscribed by the four interconnected walls. A header adapter is moveable relative to the feederhouse frame. The header adapter has an adapter sidewall disposed adjacent a feederhouse sidewall of the four interconnected walls. A torque stop is positioned within a gap formed between the feederhouse sidewall and the adapter sidewall. The torque stop has a low-friction bearing surface that is configured for bearing directly on one of the adapter sidewall and the feederhouse sidewall upon deformation of the frame to reduce friction between the adapter sidewall and the feederhouse sidewall.

摘要： A feederhouse for an agricultural vehicle includes a frame including opposing side walls, openings disposed in each of the side walls, and an assembled driveshaft including a shaft and a plurality of sprockets that are rotationally fixed to the shaft. The assembled driveshaft is positioned within an interior region of the frame. At least one opening of said openings is sized such that the driveshaft can pass in a transverse direction through the at least one opening.

摘要： A feederhouse for an agricultural vehicle includes an assembled driveshaft having a shaft and at least one sprocket that is rotationally fixed to said shaft. A shield assembly is positioned adjacent the sprocket, wherein the shield assembly includes two components including a top component and a bottom component. The top component includes a first mating surface and a first wall. The bottom component includes a second mating surface and a second wall. When the two components are connected together by joining the first mating surface to the second mating surface, the two components form a first opening through which the shaft is positioned. A bearing component is configured to bear on both the first wall and the second wall for urging the first mating surface toward the second mating surface in order to limit the top component from separating from the bottom component.

摘要： An agricultural vehicle feeder assembly having: a feeder housing, a shaft mounted to rotate relative to the feeder housing, first and second rotary drives mounted to rotate with the shaft at a first and second axial positions along the shaft, and an anti-wrap cover assembly extending an entire distance from the first rotary drive to the second rotary drive and at least partially surrounding the first rotary drive, the second rotary drive, and the shaft between the first rotary drive and the second rotary drive. The anti-wrap cover assembly is rotatably mounted the first rotary drive, the second rotary drive and/or the shaft. A connector joins the feeder housing to the anti-wrap cover assembly. The connector is configured to allow the anti-wrap cover assembly to move through a predetermined limited range of motion relative to the feeder housing.
