Crop residue flow guide with flow-through capability for a rotary crop residue spreader of an agricultural combine.

摘要

A multiple finger flow guide (36) for a crop residue spreader (14) including an element (20) disposed in a housing (18) and rotatable in a predetermined direction (B) about an axis for driving a flow of crop residue (A,C) through a discharge opening or outlet (34) of the housing (18) located at a predetermined angular position around the axis. The flow guide (36) includes at least two elongate fingers (38), the fingers (38) having proximal ends (40) located adjacent to an upstream end of the discharge opening (34) and the fingers (38) extending from the proximal ends (40) generally circumferentially to an arcuate or circular path of the flow to distal ends (46) located spaced outwardly from the housing (18) and the discharge opening (34), adjacent ones of the fingers (38) defining spaces (42) therebetween such that a desired portion of the flow (C) will pass through the spaces (42) so as to be spread onto an area of an agricultural field adjacent to the spreader (14) and the remaining portions of the flow (C) will be guided along the fingers (38) so as to be spread over portions of the field a desired distance away from the spreader (14), such that the crop residue will be distributed evenly over a desired portion of the swath of a combine (12) on which the spreader (14) is used.
