Description

Ice-cutting machines are known, consisting of an internal combustion engine mounted on a movable frame, a winch with a pull rope and a rotating milling cutter.

In the proposed machine, in order to simplify the design and quickly replace the cutter elements that were out of operation, the latter is made in the form of a cone-shaped shaft, on which a system of paired, mounted on two opposite sides of the shaft, removable plate knives is staggered.

FIG. 1 shows the proposed car, front view; in fig. 2-mill ice-cutting machine; in fig. 3 is a section along A-A in FIG. 2

The ice-breaking machine contains mounted on a mobile frame / engine 2 internal combustion, a winch 3 with a pull cable 4 and a rotating cutter 5. The latter is made in the form of a cone-shaped shaft, on which a system of paired, mounted on two opposite sides of the shaft, detachable laminated knives 6 and fixed 7. When out of operation, the knives b and 7 can be easily replaced with serviceable ones, for which it is only necessary to lay down the strips 8.

When the engine 2 is running, the queen 5 rotates and cuts the ice, and the entire machine moves from the winch 3, while the free end of the pull thios 4 is fixed at a distance from the mashine determined by the required length of the kerf in the cut ice.
