Bale Wrapping Mechanism

摘要

A bale wrapping mechanism has a roll holding station and a duckbill provided for clamping one end of the roll of wrapping material, said duckbill being pivotally mounted, via at least a first hinge, to the baling chamber sidewalls, for delivering said wrapping material to said baling chamber by insertion of said duckbill between adjacent rolls of said baling chamber, wherein the wrapping mechanism further has at least a first guiding roll for guiding the wrapping material between said roll holding station and said duckbill, wherein said first guiding roll axis substantially coincides with the first hinge axis.

1. An agricultural round baler comprising:
a main frame; a baling chamber supported by said main frame, said baling chamber having a pair of opposing sidewalls, and a pair of stationary, adjacent rolls which are rotationally affixed to said sidewalls; means for feeding crop material into said baling chamber for forming therein a cylindrical bale having a cylindrical portion and a pair of opposing ends; and a bale wrapping mechanism comprising a roll holding station provided for holding a roll of wrapping material, the mechanism further comprising a duckbill provided for clamping one end of the roll of wrapping material, said duckbill being pivotally mounted, via at least a first hinge, to the baling chamber sidewalls, for delivering said wrapping material to said baling chamber by insertion of said duckbill between said adjacent rolls of said baling chamber, wherein the wrapping mechanism further comprises at least a first guiding roll for guiding the wrapping material between said roll holding station and said duckbill, said first guiding roll axis substantially coincides with the first hinge axis in such a manner that pivoting said duckbill has no significant influence in the wrapping material distance between the duckbill and the roll holding station.
