Abstract:
1. A grain reaper comprising: A) a box-shaped structural housing having an anterior portion and a posterior portion; B) a wheel set mounted to a lower surface of said structural housing; C) a passageway mounted to said anterior portion of said structural housing, said access walkway having a handrail and a side stair; D) a coupling shaft mounted to said anterior portion of said structural housing and extending outwardly from said anterior portion of said structural housing, said coupling shaft having an internal first cardan takeoff, said coupling shaft adapted to couple the grain reaper to a tractor; E) a double gathering set, said double gathering set mounted in a support structure and comprising F) a distributing roller, said distributing roller mounted transversely at said anterior portion of said structural housing posterior to said joining roller and adapted to displace gathered plant materials from said central portion of said joining roller, said distributing roller adapted to rotatably communicate with said first cardan takeoff, said distributing roller adapted to separate gathered plant material into a first stream and a second stream such that said first stream is directed to a first beating roller and said second stream is directed to a second beating roller, said first beating roller and second beating roller mounted parallely and axially within said structural housing, said first beating roller and said second beating roller adapted to separate gathered plant materials into grains and discardable remainders, said first beating roller and said second beating roller each having a vibrating sieve, each vibrating sieve extending in a around said first beating roller and said second beating roller, each vibrating sieve adapted to retain large diameter particles such as grain and plant materials while allowing smaller diameter particles such as dirt to be discarded; G) a spreading set, said spreading set internally mounted transversally at said posterior portion of said structural housing below said first beating roller and said second beating roller, said spreading set adapted to separate the large diameter particles retained by said vibrating sieve into a stream of heavy material and a stream of lighter material while allowing clean grain to pass through said spreading set to the end of said first beating roller and said second beating roller; H) a double ventilating and discharge set, said double ventilating and discharge set communicating with said first beating roller and said second beating roller, said double ventilating and discharge set having a first lower outlet adapted to dispose the stream of heavy material and a central outlet adapted to dispose the stream of lighter material; and I) a gathering channel adapted to communicate clean grain from said first beating roller and said second beating roller to at least one horizontal transporter at least one vertical transportation elevator adapted to transport clean grain from said gathering channel to a grain bucket, said grain bucket located at the top of said structural housing, said grain bucket adapted to store clean grain, said grain bucket having an inclined bottom surface that facilitates collection of clean grain at one side of said inclined bottom of said grain bucket.
