Specially shaped auger compactor housing section for effecting even distribution of material into bale-forming chamber having rectangular cross section

Abstract From the Canadian patent

A baler for forming parallelepiped bales includes an auger compactor located within a mainly cylindrical auger housing having a rear transition section including four corner feed structures spaced equally about the auger housing longitudinal axis. Each corner feed structure is defined by a pair of walls joined to define a corner which leads to a respective corner of a rectangular cross section bale-forming chamber at the rear end of the auger housing. The junction of one of the walls of each corner structure with the cylindrical auger housing is generally oriented so as to be crosswise to the direction of the auger flighting as it passes beneath the junction. A stripper plate is located …
