ICE-AXE WITH A MOBILE ELECTRIC DRIVE Russian patent published in 2006 - IPC F25C5/00 

FIELD: the invention refers to fishing implements designed for making craters in thick ice.

SUBSTANCE: the arrangement has an auger-ax part consisting of a hollow shaft, a beam with removable axes is welded to one of its face. To the surface of the shaft one screw blade is welded from the part of the beam. At that to the second face of the shaft a lengthen shaft and a reduction gear with an engine and two hand levers is jointly connected. The body of the reduction gear is provided with a tubular extension in which an input shaft of the reduction gear is coaxially located, in the end part of the shaft there is an opening fulfilled transversally to the shaft. From the face of the shaft till the transversal opening a conical opening is fulfilled, through which a domestic accumulator drill is jointly connected with its shank. The axle of its shaft is placed under an angle of 90⁰ relatively to the axle of the shaft of the auger-ax part connected with the output of the shaft of the reduction gear. One of the hand levers in the shape of a detachable pipe with a handle is installed relatively to the second fulfilled in the shape of a drill under an angle of 90 to 120⁰ from the axle of the shaft of the drill. Besides the wall of the tubular extension from the side of the face is provided with longitudinal grooves and on its exterior surface there is a slit ring with a coupling bolt. The lengthen shaft is provided with an additional back-folding handle located at the height L from the apexes of the axes. From the side of the working surface the blade of the auger is provided with a board which is welded to the periphery of the working surface of the blade in separate points, in intervals between them the board is provided with hollow slots located on definite pitches one from another.

EFFECT: the invention excludes gas pollution, reduces noise pollution, increases effectiveness of ejection of icy crumbs out of the crater at its drilling, reduces the weight of the construction, reduces physical fatigue of the fisherman.
