Abstract:
A grain dryer, comprising:a wall assembly having (i) an inner wall and an outer wall which defines a grain flow path therebetween, and (ii) a discharge slot defined in said wall assembly through which grain may flow;a grain shelf floor positioned relative to said wall assembly such that grain flowing through said discharge slot advances onto said grain shelf floor, said grain shelf floor has a hopper opening defined therein; anda floor sweep assembly having a wiper, wherein (i) said wiper includes a blade support and a blade attached to said blade support, (ii) said floor sweep assembly is positioned vertically above said grain shelf floor such that rotation of said floor sweep assembly causes grain positioned on said grain shelf floor to be pushed across an upper surface of said grain shelf floor by said blade until said grain falls through said hopper opening, and (iii) a first lower edge of said blade contacts said grain shelf floor so as to slide across said upper surface of said grain shelf floor as said floor sweep assembly is being rotated,wherein said blade support includes a second lower edge, andwherein said blade is attached to said blade support such that said second lower edge is maintained spaced apart from said grain shelf floor as said first lower edge is slid across said upper surface of said grain shelf floor.
