FIELD: agriculture.SUBSTANCE: invention can be used, in particular, for sharpening cutting pairs of shearing machines. Device comprises a framework, on which electric motor with grinding disc, covered with protective casing, holder for fixation of a sharpened comb or knife cutting pair, means to feed suspension on grinding disc and U-shaped vessel. Suspension feed means is made in form of embedded in upper part of protective case deflector with arc-like edge made along radius, inclined to centre of sharpening disc. Grinding disc is mounted with possibility of partial submersion into U-shaped vessel filled with suspension, and its inclination angle variation in vertical plane by changing inclination angle of bed.EFFECT: present device has simple design and reduces power consumption in process of sharpening.1 cl, 3 dwg |
