    2. A digging machine tooth according to claim 1, characterized in that the fixing element is made in the form of an u-shaped bracket, and the paws of the tip have transverse grooves under the ends of the bracket.
    3. Tooth of the earthmoving machine: in accordance with claim 1, characterized in that the length of the helical ridge of the protrusion is greater than the length of the part of the surface of the body of rotation on the edges of the protrusion.
    The invention relates to the development of soils, namely to the teeth of the executive bodies of earth-moving machines.
    The aim of the invention is to increase the strength of the joint.
    FIG. 1 shows a tooth for earthmoving machines; general view; in fig. 2 and 3, respectively, the locking and locking elements; in fig. 4, the holder 3y6aj in FIG. 5 - tooth tip; in fig. 6 is a section A-A in FIG. 1) in FIG. 7 is a section BB in FIG. 1j in FIG. 8, 9 and 10 - the course of assembling a tooth using a special tool; in fig. 11 form protrusion holder; in fig. 12 . 13 and 14, respectively, sections B-B, G-D and D-D in FIG. eleven.
    The tooth of the earthmoving machine includes a tip 1 with a cutting part 2 and a longitudinal hole 3 under the pyramidal protrusion 4 of the holder 5, the stop 6 and the locking 7 elements. The locking element has the form of a bracket with ends 8. The tip is made with two longitudinal legs 9, in which there are transverse grooves 10 under the ends of the bracket. The holder has a longitudinal grooves 11 under the paws of the tip and the transverse groove 12 under the latch. The faces 13 of the pyramidal protrusion are provided with parts of the surface of the rotation body 14, and the surface of the tip opening has longitudinal recesses 15 for parts of the surface of the rotational body, while the ribs and 16 of the holder protrusion are made: in the form of helicoidal guides 17 the surface of the longitudinal hole of the tip. Parts of the surface of the body of rotation on the protrusion of the holder may have either a conical surma formed by rotating a straight line at an angle to the front one. tooth axis, or by rotating another
    curve, for example parabolas. D1; ina
    these surfaces are smaller than the length of the ribs.
    On the upper surface, the holder is made a longitudinal groove 18, E which enters the protrusion 19 of the protective cap, and the side surfaces of the holder have grooves 20 for the side flanges 21 of the protective cap.
    Assembling the tooth of the earthmoving machine by turning
    5 handpieces in the holder at an angle of 45, after which the locking element 6 is inserted in the form of a protective cap, and then a retainer which is held due to the deformation of the ends 8 of the speed 7. For ease of changing the handpiece, a special tool 22 is used. FIG. fO 11
