In front on the beam the chisels are attached in the cylindrical brackets. The chisels contain tubular racks of round cross-section with a rounded end with an oblique cut and chisels in the form of elliptical plates with soldering of metalloceramic alloy. Downstream of movement the projecting shafts with additional equipped supports are attached in the cylindrical bearing units. The supports are fixed by the plate and cylindrical brackets on the chisel racks are equipped with a welded mouldboard under the beam. At the upper part the mouldboard is designed as a vertical trapezoidal plate with two symmetrically fixed rounded wings. In the lower and middle part the mouldboard is equipped with holes for mounting with bolts of removable cutting semi-hoes in the form of semi-discs. The projecting shafts with the mouldboards have the ability of rotation by the drive comprising a pad mounted on the edge of the beam, with an electric motor, a worm gear with limit switches, and a shaft with the elements of worm gear of rotation of tooth wheels rigidly mounted in the upper part of the projecting shafts.

EFFECT: expansion of technological and functional capabilities of the tool, as well as reduction of energy consumption, and increase in operational reliability.
