Machine for making holes in the earth |
摘要 |
The machine is intended to replace the manual digging of holes for inserting posts, etc., and reduce the cost in the process. This is achieved by the machine boring into the earth "automatically" by means of a cutter and at the same time conveying the earth loosened by the cutter to the earth's surface via an auger.
