Description

  The present invention relates to an excavated earth and sand compacted auger capable of efficiently packing ordinary garbage, industrial waste, incinerated ash, general earth, and the like into a hole wall.

  Rather than discharging all of the excavated earth and sand to the ground, compacting part or most of it to the hole wall not only saves the time and effort of discharging the earth and sand, but also prevents the hole wall from collapsing. Since the frictional resistance is reduced, deep excavation is possible, and even if there are cobblestones or rolling stones in the ground, continuous excavation is possible while adjusting the surface pressure of the cutting edge necessary for excavation as needed.

  In addition, when this is done at a waste disposal site that is already full, it is possible to create a hole without putting the waste already discarded at the waste disposal site onto the ground, and the newly filled waste is filled with garbage. (Or dust and earth and sand) are also consolidated into the hole wall and sequentially filled into the hole bottom, so that a large capacity can be filled in a limited vertical hole space.

The following patent document was filed by the inventor first and obtained a patent as an excavated earth and sand compacted auger. As shown in FIG. 12, an excavated earth and sand consolidated auger 18 has a rod 3 and its tip as in a normal auger. The auger head 12 and the rod 3 are coupled to a drive device 2 that can be lifted and lowered from a top sheave of a leader mast of a heavy machine, and hang down freely in a forward and reverse direction.
