Abstract

The present invention relates to an excavating screw for agricultural use, and more particularly, to an excavating screw for agricultural use comprising: a screw body arranged to prepare a hole of a predetermined depth into the ground to install facilities for cultivation of horticultural products, install pillars of vinyl house, or to cut kudzu roots; a transfer screw formed at the upper portion of the screw body to transfer and discharge stuffs produced from the excavation in an upward direction; and an excavating blade arranged beneath the transfer screw to excavate the ground in an easy way and scoop up earth and hard objects such as stones or the like onto the transfer screw in a stable fashion. The excavating screw of the present invention is configured in that the transfer screw is formed at the upper portion of the screw body, and the excavating blade is arranged at the lower portion of the screw body to excavate the ground. The excavating screw of the present invention comprises: the transfer screw having a screw blade arranged into a spiral shape swirling along a rod to transfer and discharge stuffs produced from the evacuation in an upward direction; and the excavating blade having a needle-shaped end cutting part formed at the lowest end thereof to dig into the center of the area to be excavated, a side cutting part which is arranged onto the end cutting part, and is upwardly sloped to dig into the side portion of the area to be excavated and scoop earth or stones in an upward direction, and a rotary cutting part which rotates in an arc outside the radius of rotation of the side cutting part to dig into the area.
