    The invention relates to the mining industry, in particular to the working bodies of earth-moving machines, having a protective coating on surfaces of abrasive wear. The aim of the invention is to reduce the complexity of the restoration of a protective coating. FIG. 1 schematically shows a dragline excavator bucket, a bottom view; in fig. 2 - manual and supporting part of the element of the skid; in fig. 3 is a section A-A in FIG. one; in fig. 4 - working and supporting part of the element, the initial moment of the connection; in FIG. 5 the same, in assembled wire, in FIG. 6 pprrna part of the item; in fig. 7 is a section BB in FIG. 6; in fig. 8 is a section through BB, FIG. 6, in FIG. 9 - the working part of the element; in fig. 10 view D in FIG. 9; in fig. 11 is a section d-d in FIG. one; in fig. 12 is a section E-E of FIG. .one. As shown in FIG. 1 Position 1 indicates the body of the dragline bucket, having a pair of opposite side walls 2, rear wall 3 and open front end k (pharynx). The back wall 3 passes into the lower wall 5, which ends at the open front end. The front chains of the side walls 2 are attached 6, and the intermediate chains of the side walls 2 are attached to the intermediate side 2 of the side walls 7. The front grille (cutting edge) of the bottom wall 5 is equipped with a set of protruding cutting teeth 8. The longitudinal direction of the slider As there are several, distributed in the transverse direction along the bottom wall (bottom) 5 of the bucket and forming a protective coating. Each runner 9 contains several bores 10 of longitudinal elements (FIG. 2), welded to the bottom 1 and arranged in series. FIG. 2, the subsequent supporting part of the element is shown by fragmentary dashed lines. The support part 10 of the element, located directly but behind the support part of the element, is shown in FIG. 2 with solid lines, as well as with dashed lines. With each support part 10, the working part 11 of the element of the skid 9 is connected by means of detachable connection. 1 As shown in FIG. 3 there are several supporting suits 10 of the elements of the skid 9 attached, for example, nocpeflCtBoM Welding to the bottom 5 and passing to the back wall 3. They are located flush with each other and actually form a continuous guide for the same number of working parts 11 elements of the skid 9 As shown In the drawings, each working part 11 of the skid 9 is mounted by moving in the direction of the arrow in FIG. In the end, the working part 11 of the element of the skid 9 extends a short distance behind the support part 10, as shown in FIG. 5. As a result, this provides a reliable closure provided by the diverging walls of the detachable joint in the form of a dovetail. After the installation of the working parts 11 of the elements of the skid 9 (Figs. 1 and 3), they are fixed in place by adding a number of front limits:. low stops 12 in front of the front elements of the skids 9 behind the teeth 8. The normal advance of the dragline bucket forwards causes an action of the directional (precipitating) force on each element of the skid 9. Only in rare cases does the bucket be pulled back along the ground, resulting in runner 9 will act force, seeking to move them from the ground. In this way . There is no need for rigging. In a solid front stop to hold the elements of the skid. In addition, when using an easily removable stop (pad), it is easier to remove and replace the working parts of the 11. Elements of the skid 9., /. In order to protect the elements of the skids 9 against the rarely pulling the bucket in the direction of the yazad, rear limit stops 13 are provided (Fig. 3). They can serve as part of an eight-inch steel pipe, cut in the longitudinal direction. The pipe protrudes downward, blocking the rear element of the skid 9 and thereby preventing it from moving out of place with an unusual movement of the bucket in the backward direction. I FIG. 6-8, the support part 10 of the element of the skid 9 is shown, which is a relatively elongated plate-part. Rear end 1, i.e. The end positioned when installed at the rear end of the bucket is expanded in the transverse direction, as a result of which it forms projections 15. They are safety stops for the working part 11 of the element of the skid 9, as shown in FIG. 5. Each of the side faces 16 of the support part 10 is made of a shaft 9 inclined towards the axis and diverging in the direction from the jaw j to the back wall 3 of the surface 17 18, 19 and 20 of the detachable joint. The slope goes at an angle of about 30 to the vertical. The discrepancy (when moving in the backward direction) is approximately IS to the longitudinal axis, i.e. axes along which it is advanced during installation, as shown by the arrow in FIG. k working part 11 elements of the skid 9. The inclination of the slope and divergence provide a particularly advantageous installation of the working parts of the 11 elements on the supporting parts of the 10 elements. The slots 15 act as safety stops when the gap between the side faces facing each other and the walls of the plug connection on the elements larger than o6bs4Ho. Such surfaces on the working part 11 of the element, clearly shown in FIG. 9 are indicated by the positions 17, 18, 19 and 20 and correspond to the surfaces on the support part 10 of the element to which they are facing. As shown in FIG. 9 and 10, the rim of the element 11 of the skid 9 is also a plate-shaped piece, rectangular in the plane forming the lower lyceum surface 21, which, when the skid 9 is mounted, slides over the ground. The upper surface 22 is provided with a longitudinal groove 23 for the support part 10 of the element (see Fig. 12, where the position 23 denotes the bottom of the groove). As mentioned earlier, the surfaces 17-20 on the working part 11 of the element of the skid 9 are arranged equally with the corresponding surfaces on the supporting part 10 of the element, i.e. the surfaces 17-20. In both parts of the element, these surfaces are made in the form of two pairs separated in the longitudinal direction, in each of which the surfaces are located on opposite sides of the parts of the elements. This effectively reduces the amount of displacement,. necessary for assembly, for which the supporting part 10 of the element is provided with opposite grooves Z and 25. The ego allows surfaces 19 and 20 to be inserted into them, as shown in FIG. C. Similarly, the opposite grooves 26 and 27 are made in the working part 11 of the element of the skid 9 to accommodate the surfaces 17 and 18 of the detachable connection (Fig. 4). After the installation is completed, the said grooves are aligned on the same line. - in the middle of the groove 23 a small recess 28 is also provided (FIG. 12). Due to this, the middle part of the groove 23 is not higher than its side parts in the place of the support. The upper surface 22 extends only part of the length of the element, as a result of which a step 29 is formed (FIG. 10), which can interact with the protrusions 15 as shown in the right part in FIG. 5 The remainder of the rear part 30 extends beyond the bounding part 10 of the element, the passage under the rear support part 10 of the next element. The rear end 31 of each working part 11 of the element of the skid 9 is curved in accordance with the front end 32 of the neighboring element (FIG. 3). Bucket excavator dragline works as follows. Each runner 9 contains p supporting parts 10 elements (FIG. 2), welded to the bottom 5 of the bucket body. After installing the supporting parts 10 of the elements 9, the working parts 11 of the elements of the vine 9 are successively installed. For example, the leftmost working part of the element 11 of the rod 9 (FIG. 3) is installed, placing it on the supporting part 10 of the element as shown in FIG. 4. At the end of the mounting operations, the front limit is installed, P (FIG. 3), which prevents the elements of the skid 9 from detaching in the event that the bucket is pulled backwards. In addition, they provide protection for the end of each runner of a protective (restrictive stop) device 13, preventing the protruding part from engaging 30 elements of the runner 9 stone or the like, which can disrupt the working suit 11 of the polo element.
    for 9 ,,
    The replacement of the skids 9 can be easily ensured simply by cutting the stops 12 by means of oxygen cutting and removing some or all of the working parts of the 11 elements of the skid 9 that have become excessively worn out. This can be done at the place of operation with minimal downtime, which is important because the buckets in question are used in remote and often uninhabited places, and their size (50–150 cubic meters, or 3,811 cubic meters) makes it expensive to remove them. action For example, for a bucket of the above size, each skid element has a length of approximately 16 inches (AO, 6 cm), a width of approximately 13 inches (33 cm) and a thickness of approximately k inches (10.1 b cm). By separating the skid 9 into parts, interchangeable elements are obtained, not only more convenient to handle, but also easily adaptable to the curvature of the bucket, as opposed to using the corresponding overhead skids, which are bent according to the curvature of the bucket. .
    The advantage of the bucket according to the invention is that the supporting parts 10 of the elements welded together in the longitudinal direction form the lower support for the lattice part of the bucket, which eliminates the need for additional supports for this purpose.
