Abstract

The step-down device is an apertured round pipe that has slanted steps periodically disposed along the vertical length of the pipe interior and which only radially extend a short distance into the pipe interior. The slanted steps, which may be located on alternate (opposite) sides of the pipe interior, force the seed to cascade down the pipe bouncing off the steps and interior of the pipe. The step spacing determines the total all distance of the seed, which is insufficient to cause damage to the falling seed. The vertically spaced-apart apertures permit the seed to flow out from the pipe interior into the bin when the level of seed in the bin reaches each aperture.
