FIELD: mining and construction, particularly cutting devices for insulation wall erection in ground. ^ SUBSTANCE: cutting device comprises frame, at least two disc cutters installed on the frame so that they may rotate about two parallel axes by means of drive, adjusting means to regulate spacing between axes of disc cutter rotation. Adjusting device comprises toggle mechanism and at least one hydraulic cylinder for toggle mechanism activation. Hydraulic cylinder is carried by frame and is arranged substantially in center between disc cutter rotation axes. Each disc cutter is installed on support sheet. Both support sheets are mounted on frame and may rotate. toggle mechanism includes two levers hingedly connected to central hydraulic cylinder by the first lever sides and to one of said support sheets by the second sides thereof. ^ EFFECT: increased reliability and economy of cutting device for ground excavation with adjustable axle spacing. ^ 10 cl, 16 dwg |
