    A mineral mining plough has a plough body provided with a carrier supporting roof-level cutters. The carrier is movable vertically with respect to the plough body so as to adjust the cutting level of the roof-level cutters. A worm mounted on the plough body and a toothed rack attached to the carrier constitute means for adjusting the vertical position of the carrier, the worm meshing with the toothed rack.

    one
    The invention relates to mining engineering, in particular, to plow-type executive bodies for underground mining of coal or other minerals with an upper tool holder, which can be vertically moved by means of an actuator relative to the body.
    Known plow including housing with cutters, upper tool holder and springs
    The disadvantage of such a plow is that the upper toolholder does not ensure reliable follow-up of the formation contact with the roof.
    A plow is known, including a housing with a groove and a cutter, an upper tool holder and a vertical movement mechanism with a C2 handle.
    The disadvantage of this plane is that; that the plow body requires a relatively large space and that the mechanism of verticillary movement is subject to contamination and corrosion, and this negatively affects the performance.
    The aim of the invention is to reduce overall dimensions and increase reliability.
    The goal is achieved by the fact that in a pitch including a housing with a groove, an upper toolholder with a directional element and a mechanism for vertical movement, the latter is arranged in the form of a screw that interacts with the toothed notch of the guide element, to which the upper toolhook is pivotally attached, that the groove of the plow body is T-shaped, that the plow body is equipped with a camera for accommodating a screw that is complete in the form of a non-self-driving one-way
    15 of the worm gear and a non-winder 1 1 of the two-way worm gear, and the worm are equipped with a handle with a lock.
    FIG. 1 shows the top view.
    20 parts of the plow with an upper tool holder and a mechanism for vertical movement from the side of the bottom to the frame. 2 is a partial top view of FIG. one; in fig. 3 - section aa
    25 of FIG. 2
    The plow bears on its housing 1 an upper tool holder 2 mounted for rotation about a pivot axis 3 on a guide
    30 element 4. Guide element 4
    movably placed in the T-shaped groove 5 of the housing 1 plow. The upper tool holder 2 and the guide element 4 therefore have the possibility of being vertically displaced relative to the plow body 1. The plow body 1 is moved along inclined guides mounted on the downhole side of the mine conveyor.
    The pivot shaft 3, which has the upper tool holder 2 pivotally attached with the possibility of vertical movement to the guide element 4 driven in the T-slot 5, is located at the lower end of the guide element 4. It is installed perpendicular to the bottom and direction of movement of the plow, so the sets b and 7 incisors of the upper toolholder 2, depending on the direction of movement of the plow, can be moved in such a way that, in accordance with the direction of movement, the tool located in front of the set of incisors is in working position, while the set of incisors following it is moved away from the bottom, i.e. will be in an idle position.
    To implement the vertical movement of the upper tool holder 2, the directional element 4 has a tooth on the return side. notch 8, with which one or two double-end worm gear 9 is engaged. The worm gear 9 is located protected in chamber 10 in the upper part of the plow body 1, with the worm gear local shaft 11 protruding from the top of the worm gear chamber, so that A handle 12 (in this case with a semicircular head) can be mounted on this end with which the worm gear 9 rotates.
    Handle 12 is located in recess 13 on the top of the plow body. By rotating the worm gear 9 with the help of the handle 12, the guide element 4 and, accordingly, the upper tool holder 2 can be moved vertically. The worm drive cannot self-brake ;. In order to fasten the guide of the element 4 and together with the upper tool holder 2 in a certain position / you need the handle 12, which is in contact with the worm wheel shaft 11, for example through a hexagon, secured by means of the lock 14 against an arbitrary displacement. Handle 12 for reforming the upper tool holder 2 is activated after removal.
    clamps 14 or after installing it above clamps 14 on the shaft 11 of the worm gear. Vertical movement can be performed from the side of the worked-out space, and, moreover, due to the presence of a worm gear, this does not require excessively large manual efforts. The limit of movement is determined by the length of the toothed notch 8 of the guiding element 4. In the drawing, the upper tool holder 2 is shown in a lowered position, in which the sets 6 and 7 of the cutters for forming the cut-off piece are partially lowered below. on the body of the plane of cutters 15, 16
    5 The incisors for the formation of the advanced cutting unit, as well as the soil incisors located below the incisors 15, 16, are not shown separately in the drawings.
