 Anyone ever use one of these? Or has anyone seen plans for making one?

That is what the back end of a combine is. After the stalk is cut the plant runs through a cylender designed to deal with the type of plant, anything from small like clover of rape seed  to rice or wheat on up to grain sorgum or corn. Then the material is dumped across the screens where the grain is shaken down to a catch tray and air is dirrected up through the plant matter. The fans and wind boards can de set to blow the grain out the back of the machine but ideal is to stop just short of that. The chaff and straw, tailings, are walked out the back by the straw walkers.  Mother Earth News had one set up stationary to clean grain IIRC. I delt with combines for many years is my only experience.  ear

Dad had an old machine he fixed up and got running. He called it a fanning mill. It hat 3 sets of inclined screens running back and forth that shook, and a blower.
 
 Whats the matter no wind where you live? I did quite a bit of threshing by hand last year, and could always count on a breeze when I wanted to winnow.

 Yeah, but She usually wastes it on her cell phone.
  A fanning mill or seed cleaner is the thing I'm looking for. We had one on the farm 40 odd years ago, and it would beat a combine for no more than we need to winnow. It would also work better on small seeds than combines back then. Don't know about newer ones. This one had straw walkers and screens and had a crank, but had been rigged up with an electric motor.
