    A cutting machine has at each side of a universally pivotable cutter boom a cutting head which is rotatably supported around an axis extending vertically to the longitudinal direction of the cutter boom and which is advanced in direction of its axis when the cutter boom is pivoted. The cutting heads are propelled by a drive unit via a reduction gearing arranged within the cutter boom, the last stage of the reduction gearing being arranged within cutting heads which are hollow.

    FIELD OF THE INVENTION The invention relates to mining equipment.
    The known executive body of a mining combine, which includes a handle, a baffle crown of two hemispheres with a horizontal axis of rotation mounted on the handle, and a drive of rotation of the baffle crown 1P.
    The disadvantage of this executive body of a mining combine is that when the executive body is fed to the bottom of the rock, protrusions appear that are equal to the width of the handle, which collapse when the handle rolls in a horizontal plane, which takes additional time, resulting in a lower penetration rate.
    Closest to the proposed technical essence and the achieved result is the executive body of the mining combine including a hollow handle, inside which a gear drive is placed, the output stage of which is mounted on the horizontal axis associated with two hollow cutting heads, intermediate support elements and - gearboxes housed in cutting heads and fixed to the hand, the gearbox comprises a housing, a gear wheel, mounted on a coaxially horizontal axis, and associated with gears Mi 23.
    10 The disadvantage of this. The main part of the body is that the arm has a large width and therefore, to eliminate the formation of protrusions between the cutting heads, wedge rollers are mounted between them, which are connected with the output gear stage by means of a gearbox. Reducing the width of the handle in the specified executive body is possible
    20 only if the torque transmitted by the output gear stage decreases, however, in this case the cutting force will decrease, which reduces the efficiency of the actuator.
    The purpose of the invention is to increase the efficiency of the executive body by reducing the width of the arm by reducing the transmitted torque by the output gear stage.
    The goal is achieved by the fact that in the executive body of a cutting machine, a hollow handle is turned on, inside of which a drive with a gear is placed, the output stage of which is mounted on a horizontal axis and associated with two hollow cutting heads, intermediate support elements and gearboxes, each of which contains a body fixed on the handle, a gear wheel mounted coaxially with the horizontal axis associated with the gear, and housed in the corresponding cutting head; the intermediate supporting element is made in the form of the hollow fixed to the handle, the carrier on which the gears are mounted, a gear wheel is placed inside the carrier, and the gearbox housing is connected by means of a coupling with a cutting head and has.-. ring gear for internal engagement with gears.
    In addition, the gears are connected by means of a central screw with a horizontal axis, which has cams, and the gearbox housing is connected to the handle by a labyrinth seal.
    FIG. 1 shows a cut-in machine, side view; in fig. 2 - the same plan; FIG. 3 is a part of the handle, top view.
    The executive unit of the cutting machine consists of a hollow arm 1, which is connected to the chassis of the cutting machine 2 for rotation around a vertical 3 and horizontal 4 axes. On the front end 5, the arms 1 are equipped on both sides with cutting heads 6 and 7 mounted on a horizontal axis 8. The cutting heads are rotated by means of an actuator that has a gear 9, on which drive shaft a small bevel gear 10 is mounted. in engagement with the larger bevel gear 11, the key on the key is mounted on the shaft-gear 12. With the gear 12 there is an engagement cylindrical gear 13, freely mounted on the shaft 14. Gears 10, 11, 13 are installed in the hollow arm 1. The gear 15 is mounted on the front end 5 of the arm 1 by means of a pair of bearings 16 in the housing 17 of the arm 1. Inside the gear 15 there are two coaxial bushings 18, which are connected to the gear 5 through the cams 19. By means of spring rings 20, which interact with the shoulders 21, the sleeves 18 are secured against axial displacement in the gear IS. The two gear wheels 22 are connected to the sleeve 18 by means of cams 23, mounted to each other by a central screw 24.
    A planar gearbox is attached to the handle 1, the casing of which has a gear rim 25 for internal engagement with gears 26. In each cutting head there are three gears 26 with a circumferential shift on. The gears 26 are mounted in an intermediate support member 27, made in the form of a carrier, which are rigidly connected with bolts 28 to the body 17 of the handle 1. The sleeve 29 is rigidly connected to the ring crown 25 and the sleeve 30 is rotated to the crown 25. on a roller bearing 31 rigidly mounted on the driver, and the annular sleeve 30 rotates on the bearing 32. The sleeve 29 is connected by means of a labyrinth seal 33 with the handle 1, and the bolts are attached to the ring sleeve 30. The inner space of the reducer is completely insulated ano from the environment and together with the interior of the handgrip 1 forms a single cavity.
    The cutting head consists of a housing 35, which is rigidly bolted to the cover 36, while the cutting head is connected to the gear housing by means of a friction clutch 37.
    The executive body of the cutting machine works as follows.
    The feeding of the cutting heads 6 and 7 occurs by turning the handle 1 around the vertical axis 3 alternately in the direction of the arrows (Fig. 2).
    At. feed to the right, the development of the bottom by the cutting head 7, and when feeding to the left by the cutting head 6. When the handle 1 reaches the extreme position (by turning) around the horizontal axis 4, the actuator is inserted into the rock to the depth. c1. The cutting heads 6 and 7 are spaced apart from each other, which is determined by the width of the front end 5 of the arm 1, so that a rock remains approximately a protrusion approximately equal to the width and height О. This projection must be destroyed or by turning arm 1 around the vertical axis 3, or must be matched. Cleavage of the protrusion requires less power than undercut, however, cleaving is possible only up to a certain width t. Therefore, this width 6 should be as small as possible. The cutting heads 6 and 7 are rotated by gear 15 with a gear ratio that determines — with the ratio of the pitch diameter of the gear ring 25. The cutting heads 6 and 7 therefore rotate slower than gear 15 and the torque transmitted by it rotation is less than the moment perceived by the cutting heads 6 and 7, and therefore the width of the gear 15, as well as the width of the front end 5 of the handle can be made already. In the proposed body, the gear ratio between the gear wheel 22 and the ring gear 25 is about 4: 1. Therefore, the torque that the gear wheel 15 must transmit is only a quarter of the moment perceived by the cutting heads 6 and 7.. Thus, the use of the proposed executive body increases the efficiency of the work; by reducing the width of the handle, which is achieved by reducing the torque acting on the gear. 5 Formula; 1. The executive body of the cutting-in machine, comprising a hollow handle, inside which is placed an actuator with a toothed cutting, the output stage of which is mounted on the horizontal axis and associated with two hollow cutting-edge heads, intermediate support elements and gearboxes, each of which includes a housing mounted on the handle, a gear wheel mounted coaxially with the horizontal axis, associated with gears and housed in a corresponding cutting head, characterized in that, in order to increase work efficiency, the smaller width of the arm, the intermediate support element is made up of a hollow carrier attached to the arm, on which gears are mounted, a gear wheel is placed inside the carrier, and the gear case is connected by means of a coupling with a cutting head and has a gear ring for internal gearing. . 2. The executive body according to claim 1. characterized by the fact that the gears are connected by means of a central screw with a horizontal axis, which has cams. 3. An executive body as claimed in claims 1 and 2, characterized in that the gearbox housing is connected to the handle by means of a labyrinth seal.
