  • Publication number: 20250241274
    Abstract: The present disclosure provides for a shaftless auger with adjustable anchor system comprising a hopper, a boot, a trough, a motor, a coreless/shaftless auger, and an anchor assembly comprising an adjustable anchor and a threaded adjustment rod. Material deposited into the hopper is gravitationally dispensed into the boot, where it fits between flights of the auger. The motor provides a rotational spin to the auger, which pushes the material longitudinally out of the boot and along a length of the trough. Moving the adjustable anchor longitudinally along the adjustment rod alters a tension on the shaftless auger and alters the amount of material that can fit between flights of the auger. When the adjustable anchor is moved forwards a dispersal volume deposited by the auger per foot of trough is reduced. Moving the anchor shaft backwards increases the dispersal volume.
