Reciprocating lobed conditioning rolls

摘要

A conditioning roll for use in a conditioning mechanism on a hay harvesting machine is disclosed wherein the conditioning roll is formed by a plurality of individual lobes slidably mounted on transverse guide members detachably affixed to a core member. Each lobe is connected to a lobe reciprocating apparatus for effecting a transverse reciprocating sliding movement with respect to the core of the conditioning roll while the respective conditioning roll is being rotated. The conditioning mechanism is provided with a pair of intermeshing conditioning rolls connected to respective lobe reciprocating apparatus so that the lobes on the respective conditioning rolls are transversely moving in opposite directions at the throat formed between the rolls through which crop material passes to be conditioned in an aggressive manner.
