Abstract:
1. A kernel processing assembly, including: a first roll, that is supported in bearings at a first frame element so as to pivot and can be rotated about a longitudinal axis; a second roll that is supported in bearings and can be rotated about a longitudinal axis and supported in bearings at a second frame element and forms a slot together with the first roll through which harvested crop can be conducted; a rotary bearing arranged on the first side of the slot that retains the first frame element and the second frame element free to pivot about an axis extending parallel to the longitudinal axes of the two rolls; and, a pre-load arrangement arranged on a second side of the slot that pre-loads the first frame element and the second frame element against each other, where the spacing between the rolls can be adjusted; wherein the rotary bearing arrangement includes a shaft to which an eccentric is rigidly fastened the eccentric being supported in the first frame element via bearings so as to rotate, and the shaft being supported in the second frame element via bearings so as to rotate, so that the distance between the rolls can be varied by rotating the shaft about its longitudinal axis thereby rotating the eccentric and effecting a relative movement between the first frame element and the second frame element.
