Grain Auger Converts To Grain Vac In Seconds
Inventor Andy Orosz introduced his prototype "Convert-A-Vac" at the recent West-ern Canada Farm Progress Show at Regina, Sask.
It consists of a conventional 7-in. dia., 34-ft. long auger with a vacuum system built onto it. Grain is pulled into a second auger tube that mounts above the original auger.
To empty a bin, you insert a stub auger into the bottom and auger grain out normally. When you get to the bottom of the bin, you remove the stub auger and insert a 6 ft. piece of 6-in. dia. flexible tubing and suction nozzle. When you activate the 8-in. Crary fan mounted halfway up the auger, enough suction is created to move up to 800 bu. per hour. Orosz notes that grain only has to be sucked into the end of the auger tube before the flighting inside takes over. A "separator" screen halfway up the auger al-lows air pressure to escape.
An air lock system for the vacuum system is created by a spring-loaded trap door on the auger discharge. The door is opened by the weight of the grain being discharged.
Orosz drives the 540 pto auger drive with a 40 hp tractor and says the conversion should work on any grain auger. He's looking for a manufacturer. Contact: FARM SHOW Followup, Andy Orosz, P.O. Box 32, Dubuc, Sask., Canada SOA ORO (ph 306 877-4535).
