    1 ROTARY DEVICE FOR CUTTING MACHINES, containing a turning head associated with the machine j frame, a mechanism for the horizontal rotation of the head, made in the form of a gear wheel mounted on a rack having a bearing disc, toothed racks connected to power jacks included in gearing with a gear wheel, and located diametrically, differing from the fact that, in order to increase reliability in operation, the swivel head is made in the form of a frame, the gear wheel is rigidly fixed on the rack and located inside the turn company head, and the stand is rigidly mounted on the body of the cutting machine, while the hydraulic jacks are mounted in the swivel head, 2. The device according to claim 1, is so tactile that each hydraulic jack is made with two pistons spaced along the body and connected by a toothed rack . 3. The device according to claim 1, characterized in that the diameter of the supporting disc is larger than the diameter of the pitch circle of the gear wheel.

    The invention relates to the mining industry, in particular to rotatable devices of the executive bodies of the cutting machines. Known rotary device of the executive body of the mining machine, containing a gear wheel, turn hydraulic jacks with toothed racks engaged with gear wheel C. The rotary device for cutting machines, containing a swivel head, is closest to the invention in technical terms and results. tied to the car body mechanism. horizontal rotation of the head, made in the form of a gear wheel mounted on a rack having a bearing disc, toothed racks connected to power jacks that engage with a gear wheel and located diametrically. 2 The disadvantage of the known rotary device of executive bodies is low reliability his work with significant cutting loads due to the console mounting of the swivel head. The aim of the invention is to increase the reliability in the operation of the rotator. The goal is achieved by the fact that in a rotary device for cutting machines, containing a rotary head associated with the machine body, a mechanism for horizontal rotation of the head, made in the form of a gear wheel, mounted and equipped with a supporting disc, racks connected to power jacks JB engages with a gear wheel, and diametrically located, the turn on the head is made in the form of a frame, the gear wheel is rigidly fixed on the rack and located inside the rotary head, and the stand gesture mounted on the body of the ironman, while the hydraulic jacks are embedded in the swivel head. In addition, each hydraulic jack is made with two pistons spaced along the body, which are connected by a toothed rack. Moreover, the diameter of the supporting disc is larger than the diameter of the pitch circle of the gear. FIG. 1 shows the cut-in machine, general side view; FIG. 2 is the same plan view; in fig. 3, section A-A in FIG. four; in fig. 4 section bb in fig. 3 in the plan; in fig. 5 is a sectional view BB in FIG. 3. The swivel device consists of a swivel head I, made in the form of a frame and a stand 2. A stand 2 is rigidly connected to the body 3 of the cutting machine. The annular support disk 4 is fixed to the rack 2 by means of bolts 5. With the rack 2, the gear wheel 6 is rigidly connected by means of bolts 7 located inside the swivel head. The swivel head 1 covers on both sides a zone 8 in which the supporting disk 4 is located. The sliding surfaces 9, with which the swiveling head 1 rests in the zone 8 of the supporting disk 4, are made in the form of gaskets 10 made of plastic. Between the outer surface 1I of the support disk 4 and the swivel head 1 a certain gap may remain, however the outer surface 1I may also adjoin the swivel head 1. In the swivel head 1 there are two gear racks 12 and 13 with the possibility of longitudinal movement, which are diametrically opposite positions x engages and engages with a gear wheel 6. With each gear rack 12 and 13, two pistons 14 and 15 or 16 and 17 are coaxially connected, respectively, of power hydraulic jacks 18 and 19, mounted in the swivel head I with working cavities E 20-23. Rotary device for the cutting machine works as follows. When pressure is applied to the working cavities 20 and 23, the head 1 is rotated with simultaneous movement of the gear racks 12 and 13, which in diametrically opposite positions are engaged with the gear wheel 6. The head 1 is rotated relative to the rack 2 through the gaskets 10 of the reference J. 1. When pressure is applied to the working cavities 21 and 22, the direction of rotation changes. Thus, due to the specified embodiment of the rotator, its reliability of operation is enhanced.
