Air Blast Auger
Showgoers at the recent Western Canada Farm Progress Show in Regina, Canada were "blown away" by a new "air blast" auger that uses air to move grain through a conventional auger tube, completely eliminating auger flighting.
The first-of-its-kind grain mover uses a big pto-blower to shoot air into the intake end of the auger. The blast of air sucks grain into the auger like a Venturi valve and then blows it up and out of the auger, according to inventor Brian Gall, Fillmore, Sask.
"It has more capacity, does less damage to grain, is safer because there's no flighting to catch a hand or a foot, and requires less maintenance because the only wear parts are 4 bearings on the blower," says Galt.
The 6-in. dia. auger requires only a 20-hp. tractor pto to direct-drive its 23-in. dia. blower, mounted at the center of the auger frame. Air, at a rate of 1460 cfm, blows down a 6-in. dia. tube to the intake end of the auger where 7 individual 2-in. dia. pipes split off to blow air into the auger. Gall says the auger will move 28-30 bu. per min., "about the capacity of a larger 7-in. auger". He's negotiating with a manufacturer to produce the auger.
