Air-Powered Grain Mover
"It saved us the cost of a $20,000 grain elevator and leg system," says Walt Trengen, Bottineau, N. Dak., who devised an air-powered grain mover using a grain vacuum and several hundred feet of flexible 5-in. dia. tubing.
Trengen uses his Walinga 510 grain vacuum to push grain from his dryer to storage bins located up to 200 ft. away. To get grain up into the bins, he removed the flighting from inside a conventional 37-ft. grain auger (which he extended another 10 ft.) and inserted flexible tubing right up to the end of the auger. The grain vacuum simply pushes grain out to the auger and then up and into the bin.
"We can push 800 to 1,000 bu. of sunflowers, barley or oats per hour with the system. I think it could push as far as 300 ft. Works great," Trengen told FARM SHOW.
The grain vacuum, which is rated at 1,500 to 2,000 bu. per hour, is unmodified except for a stove pipe vent installed at the top to pull in clean air. Trengen installed "outlets" all along the push pipe so that he can position the auger anywhere along its length to fill each of his bins. The only power required for the system is the 100 hp. Oliver tractor that powers the grain vacuum. He mounted a grain spreader at the end of the auger.
