New Slinger Throws Grain Into Storage
"It's the perfect machine for low-cost, high-volume grain handling in flat storage," says John Baumgartner of Geoponics, Inc., manufacturer of a new grain slinger that'll throw up to 7,000 bu. per hour into storage.
The heavy-built, electric-powered Slinger is equippped with rubber-coated, metal paddles that spin at high speed, tossing grain out in an arc that'll make a pile up to 40-ft. high and 200 ft. in dia. The grain Slinger is faster than conventional augers, gentler on the seed, and it makes a smooth-topped grain pile that requires less labor to handle in flat storage, according to the company.
"The front throat of the Slinger moves 30? up and down and from side to side so you can pile up a tremendous amount of grain from one spot. Grain augers must be moved continuously and they can't match the job this machine does," says Baumgartner.
A large 12-ft. auger, 12 in. in dia., feeds grain to the throwing paddles on the Slinger. Powered by a 5-hp. electric motor, the auger drops grain onto a short conveyor belt that spins at the same speed as the paddles right above it. Because the paddles and belt spin at the same speed, there's no friction between the two that could damage the grain, which is simply knocked off the belt by the paddles as fast as the auger can deliver it.
"The Slinger throwing mechanism has been used extensively for handling steel pellets, fertilizer and other materials but, so far as we know, this is the first practical grain thrower on the market in North America," says Baumgartner, noting that FARM SHOW recently featured the only other commercial grain slinger, a model made in Australia, in its Vol. 7, No. 6 issue.
The Slinger paddles toss grain at velocities up to 60 mph., powered by a 15-hp electric motor. One advantage of the self-contained unit is that no tractor is needed to power it. It can also be used for throwing grain inside a building, or into any other form of flat storage.
The company's first prototype was in use last year at local grain elevators. A 7,000 bu. per hour model, which sells for $10,000, is now in production. The company hopes to soon offer a smaller, farm-sized model.
