Hole cleaning device for augers

Abstract

A hole cleaning device which may be attached to the top of an auger or auger extension for rotation therewith includes two diametrically opposed blades arranged to resemble one flight of an auger, the outside diameter of the blades being suitably larger than the hole-digging auger itself. The two blades are secured to a mounting sleeve adapted to be secured to the upper end of the auger tube which supports the auger or to the top auger collar. To the top sides of the two blades are secured two elongated and radially extending deflecting elements, these being arcuately shaped and upstanding. As a hole is being drilled into the soil, the displaced soil is lifted and deposited onto the surface of the ground in an area around the hole. When the hole is drilled to full depth, the cleaning blades engage the soil build up, lifting and throwing it radially outwardly. For slow auger speeds, the loose soil is stacked in an annular pattern spaced from the hole. For higher auger speeds, the soil is dispersed up and away from the hole top.
