摘要
This invention refers in general to an excavator device to dig small tunnels suitable for underground channels or tube conductor systems for water flow, waste tunnels, electrical wires, gas tubes, means of communication, etc. In particular, this invention refers to a mole-like excavator device able to dig small tunnels and to push itself through the dug tunnel, not limited to the direct route, over long distances, and it is suitable in different soils, like mixed debris soils, sandy soils, etc. The mole-like, small-sized excavator device in accordance with this invention has a excavation tool able to turn at a high torque; a release tool for the dug material to turn the dug earth into mud and release the earth transformed into mud through compressed air; the working unit to operate the anterior unit back and forth; a position detection device to show the vertical and horizontal position as well as the angle of the excavation means and a direction corrector unit to correct the direction of the excavation means digger. Additionally, the excavator means includes a regulator so that the digger adapts itself to the different sizes of the passages it creates.
