The invention relates to the mining industry and can be used for open development of mineral deposits on bestransportnye system in difficult mining and geological conditions.

The invention relates to the priority direction of development of science and technology "Technology for environmental security, mining and mining", as it solves one of the problems associated with mechanization and environmental safety of surface mining.

The problem of using Stripping units is as follows.

When drawing a bucket of Stripping unit formed tracks, split rock ridges. With increasing distance between the passages bucket (tracks) performance Stripping unit increases. Decreasing this distance performance is reduced by increasing the length and duration of use rock bucket, which leads to a longer duty cycle. For cleaning of the rock ridges Stripping unit should be returned by performing an additional pass. The performance of the Stripping unit is reduced. So after work Stripping unit for cleaning the rock ridges often involved additional equipment, such as bulldozers or compact drag the Ainu. This leads to performance degradation Stripping equipment career.

The weight of the overburden unit has a significant impact on his cross as the internal ledge of the blade and Stripping ledge, Is determined by the specific pressure on the ground. The value of this indicator depends on the weight of the downhole or moldboard running non platforms with poles. Performance decreases when the deterioration of the cross.

Stripping unit unloads breed anywhere along the length of the transportation of the bucket. The bucket is moved across the upper longitudinal edge of the inner blade. It determines the place of unloading is only along the upper transverse edge of the inner blade. So adipoma into the internal dump rock rolled down and relate to the slope of the blade from the upper transverse and longitudinal edges to its Foundation. As a result all adipoma into the internal dump rock rises to the maximum height of the upper longitudinal and transverse edges of the blade. The process of laying breed to dump the dragline is similar to the process of waste rock Stripping unit. The dragline also occupait all breed only in the upper part of the blade. This leads to a maximum expenditure of energy and materials.

Thus, the problem of using a bucket of overburden unit is clochette the following:

- increased performance due to the excavation of rock in the ridges in one pass bucket Stripping unit and improve cross;

- reduce consumption of energy and materials in storage breeds in the interior of the blade by reducing the height.

Analysis of analogues of the invention have shown that the device is equipped with not more than two buckets. The performance of the device is improved only by increasing the number of buckets. However, the performance of a single bucket is reduced due to the fact that a system of ropes involved through the tail blocks. Analogues devices do not have the potential to enhance performance, not reduce the consumption of energy and materials, and make amendments, aimed at the achievement of a technical result..

For the prototype accepted Stripping unit by the Russian Federation patent for the invention №2396394, CL E02F 3/54, AS 47/00, published 10.08.2010, as the closest to the technical essence and function. Stripping unit consists of downhole and moldboard running non platforms with poles connected by a system of ropes with a ladle. Common features of known Stripping unit with the claimed invention is downhole and moldboard non-tradable platform mAh is AMI, the associated system of ropes and bucket.

The disadvantages of the known Stripping unit are:

- low productivity due to loss of time for cleaning the rock ridges between tracks for the passage of the bucket;

- high consumption of energy and materials in storage rocks in the upper longitudinal edge of the inner blade;

- low permeability as a result of high specific ground pressure due to the large weight of the downhole and moldboard running non platforms masts.

The reasons for the shortcomings of the Stripping unit is the lack of technical solutions aimed at improving the performance of the Stripping unit, reducing consumption of energy and materials, as well as to increase its permeability.

The selected prototype of the claimed invention allows to improve the Stripping unit in the direction of increasing productivity, reducing consumption of energy and materials.

The invention is aimed at solving the following tasks:

- increased performance due to the excavation of rock in the ridges in one pass bucket Stripping unit and improve its permeability;

- reducing the consumption of energy and materials in storage breeds in the interior of the blade by reducing the height.

The technical result for the implemented of the invention is to increase productivity through the excavation of the rock ridges in one pass bucket Stripping unit and improve its permeability, and also in reducing the consumption of energy and materials in storage breeds in the interior of the blade by reducing the height.

The technical result of the claimed invention is achieved in that bucket Stripping unit, including downhole and otvalnuyu running non-platform with their corresponding poles connected by a system of ropes and ladle according to the invention is additionally equipped with at least one mast downhole running rotary platform and at least one mast moldboard running non platforms connected by a system of ropes with a ladle. Additional mast installed on downhole and moldboard running non platforms along a straight line and each subsequent further installed mast hole and pile driving rotary platforms are made of a height of less previous in the direction of inclination of the slope otsypannoy Zachodni inner blade by an amount defined by the following mathematical expression:

N=S×tgα,

where H is the height difference of two adjacent poles, m;

S is the distance between the masts, m;

α is the angle of slope of the inner blade, hail.

The technical result of the claimed invention is also achieved by the fact that downhole and moldboard running non-platform claimed many who akovskogo Stripping unit configured to change their length by means of attach / detach sections.

Equipment Stripping unit, at least one additional mast downhole running non platforms, connected by a system of ropes with a ladle with an additional mast moldboard running rotary platform, increases the number of buckets from one to two. After podvigina overburden excavator along the upper longitudinal edge of the inner blade on the magnitude of the step of advancing removed the rock in the ridge between the tracks of the passage of the first and second buckets. Breed in the crests excaberate with two buckets along the entire length of the front. This eliminates the return of overburden excavator for cleaning rock ridges and improves performance.

Additional mast hole and pile driving rotary platforms, connected by a system of ropes with bucket and reduced in height in the direction of inclination of the slope otsypannoy Zachodni internal satiety, reduce raising the height of the rocks in comparison with the height of the inner blade. The result is increased performance, because a reduction in weight and specific ground pressure increases the permeability of the overburden unit. Reduced consumption of energy and materials. This contributes to the achievement of the technical result.

Reducing the height of each subsequent additional mast hole and pile driving toggling boards the Orme on the value, equal to the product of the distance between the masts on the tangent of an angle of slope of the inner blade determines the specific amount of reduction in each subsequent additional mast in accordance with the inclination of the slope otsypannoy Zachodni internal dump. This contributes to the achievement of the technical result.

The number of additional masts downhole running non platforms, connected by a system of ropes with a bucket with the appropriate additional masts moldboard running non-platform, can be equal to a single mast and multiple masts, for example, with a relatively small capacity of overburden length of the slope of the inner blade is limited. In this case, the number of additional masts may be minimal, i.e. corresponding to the length of the site an additional mast. With the growth capacity of overburden increases the length of the slope of the inner blade. The number of additional masts increases, increasing the effect from a technical result. The maximum is achieved when the masts are located throughout the length of the slope of the inner blade. The number of additional masts limited amounts of overburden Stripping length internal slope of the blade, the length of exploding block, mining and geological conditions, etc.

Bucket Stripping unit configured to change the length of the exploits of attach / detach sections, Allows you to change the number of additional masts in accordance with the terms of reference of Stripping operations. Improves performance and patency of the Stripping wheel Assembly, reduces the consumption of energy and materials. Contributes to the achievement of a technical result.

The invention is illustrated by drawings, presented in figure 1. 2, 3, 4, 5.

Bucket Stripping unit consists of 1 downhole running non platforms with poles 2, 3, 4, and moldboard 5 running non platforms with poles 6, 7, 8. Hole 1-running rotary platform 3, 5 is not visible, as shown in figures 1, 2, 3. Moldboard 5 running non-platform figs.4, 5 is not visible, as shown in figures 1, 2, 3. Mast 2, 3, 4 hole 1 running rotary platform 3, 5 are not visible, as shown in IG, 2, 4. Mast 6, 7, 8 moldboard 5 running rotary platform 4, 5 are not visible, as shown in figures 1, 2, 3. Mast 2, 3, 4 hole 1 running non platforms are connected by a system of ropes 9, 10, 11 with buckets 12, 13, 14 with the corresponding poles 6, 7, 8 moldboard 5 running non-platform.

All mast 2, 3, 4, 6, 7, 8 hole 1 and moldboard 5 running non platforms have different height.

The height of the mast 6 moldboard 5 running toggling platform to the height of the subsequent adjacent in the row of the mast 7 of this platform, and the height of the mast 7 to the height of the subsequent adjacent in the row of the mast 8 (figure 3).

The height of the mast 6 moldboard 5 running rotary platform is the highest not only among poles 7, 8 moldboard 5 running rotary platform, but also among the poles 2, 3, 4 hole 1 running non-platform. This is because the critical parameter to determine the height of the mast 6 is the distance in height between the upper longitudinal edge otsypannoy Zachodni a, b, C, e inner blade 15 (1, 2, 3) and the bucket 12 in the system of ropes 9 connecting the mast 6 and 2, moving above the upper longitudinal edge otsypannoy Zachodni a, b, C, D. the height of the inner blade a, b, C, e is the greatest.

For the next adjacent row of the mast 7 critical height of the passage of the bucket 13 above the upper longitudinal edge otsypannoy zagadki is, b, C, d inner blade 15 remains unchanged, and the height otsypannoy Zachodni a, b, C, d inner blade 15 is reduced up to the height of the slope otsypannoy Zachodni a, b, C, d of the blade in the passage of the bucket 13. This determines the amount of reduction of the height of the mast 6 to the height of the mast 7.

For the next adjacent row of the mast 8 critical height of the passage of the bucket 14 above the upper longitudinal edge otsypannoy Zachodni a, b, C, d inner blade 15 also remains unchanged, and the height otsypannoy Zachodni a, b, C, d inner blade 15 is reduced up to the height of the slope otsypannoy Zachodni a, b, C, d of the blade in the place of passage of the bucket 14. This determines the amount of reduction of the height of the mast 7 to the height of the mast 8. Thus, reducing the height of the mast 7, 8 takes place in accordance with the lowering of the height of the longitudinal upper edge otsypannoy Zachodni a, b, C, d inner blade 15 in the direction of podvigina this otsypannoy zagadki. The height of each subsequent adjacent in the row of the mast is reduced in the direction of inclination of the slope otsypannoy Zachodni a, b, C, d inner blade 5 by the value of N, is equal to the product of the distance between the poles S on the tangent of the angle α of the slope of the inner blade 5 (Fig 3). With further increase in the number of masts moldboard 5 running non-platform procedure of calculation is stored.

The most high is and mast 2 1 downhole running position of the platform is determined in accordance with the Russian Federation patent for the invention №2034114, CL 02F 3/54, published 30.04.1995. The height of the mast 2 1 downhole running non platforms must comply with the conditions of use in the area of the bottom of the Stripping edge of the ledge 16. Stripping ledge 16 on 3, 5 is not visible, as shown in figures 1, 2, 4. The height of the next adjacent row of the mast 3 is made smaller than the height of the mast 2, and the height of the next adjacent row of the mast 4 is made smaller than the height of the mast 3. The height of the masts 3, 4 reduced in accordance with reduction of the height of the upper longitudinal edge otsypannoy Zachodni a, b, C, d in the direction of podvigina otsypannoy Zachodni a, b, C, and the slope of the slope of this Zachodni inner blade 5. The value of reduction of the height of the masts N is equal to the product of the distance between the masts S on the tangent of the angle α of the slope of the inner blade 5 (figure 4). When the number of poles 1 downhole running non-platform procedure of calculation is stored.

Reducing the height of the masts 3, 4 hole 1 running rotary platform does not affect the process of bailing in the area of the bottom of the Stripping edge of the ledge 15, so at the same time as reducing the height of these poles increases the height of the collapse of the blasted overburden 27. Reducing the height of the mast 7, 8 moldboard 5 running rotary platform also does not affect the process of laying breed in otepaeae section a, b, C, g, so as to simultaneously reduce the height of these masticate unloading of the buckets 13, 14 is decreased due to the weakening of the lifting and traction rope (figure 1).

Thus, the height of the masts 3, 4 1 downhole downhole running rotary platform and the height of the mast 7, 8 moldboard 5 running non-platform reduced in two ways: podvigina otsypannoy Zachodni a, b, C, d and inclination of the slope of the inner blade 5. The value of reduction of the height of the masts N is equal to the product of the distance between the poles S on the tangent of the angle α of the slope of the inner blade 5 (Fig 3, 4).

To change the length of the Stripping wheel Assembly is made of three sections 17, 18, 19.

The length of the hole 1 and moldboard 5 running non platforms change by joining the sections 17 and detach from section 17 sections 18, 19. Section 17 comprises an area of 20 1 downhole running rotary platform with additional mast 2, connected by a system of ropes 9 with bucket 12, with the corresponding additional mast 6 installed at the site 21 moldboard 5 running non-platform. Section 18 comprises an area of 22 1 downhole running rotary platform with additional mast 3, connected by a system of ropes 10 with bucket 13, with the corresponding additional mast 7 installed on a dedicated section of the moldboard 23 5 running non-platform.

Section 19 comprises an area of 24 1 downhole running rotary platform with additional the Noah mast 4, connected by a system of ropes 11 with the bucket 14 with the corresponding additional mast 8 installed on a dedicated section of the moldboard 25 5 running non-platform.

Sections 17, 18, 19 1, 3, 4, 5 partially visible and shown in full in figure 2. The downhole plots 1 and moldboard 5 running non platforms 1, 2 are not visible. Figure 3 shows the sections 21, 23, 25 moldboard 5 running non-platform. Figure 4 shows plots 20, 22, 24 hole 1 running non-platform.

This schematically in figure 1 elements of the trench is indicated by the following positions: 26 - rock ridge; 27 - blasted overburden; 28 - layer mineral; a, b, C, d - loop otsypannoy Zachodni inner blade; a, b, C, d, e - the contour of the trench.

Bucket Stripping unit operates as follows.

Hole 1-running rotary platform with three masts 2, 3, 4 set for Stripping ledge 16 on the distance from the upper edge of this ledge, excluding the collapse of the ledge under the impact load from the downhole 1 running non-platform. Otvalnuyu 5 running rotary platform with three masts 6, 7, 8 mounted on the inner blade 15 at a distance from the upper longitudinal edge of the blade, excluding the collapse of the rock pile under impact load from the moldboard 5 running toggling is latform. Hole 1 running toggling the platform moves along the Stripping of the ledge 16. Moldboard 5 running toggling the platform moves along the upper longitudinal edge of the inner blade 15. When this blasted overburden rock 26 excaberate, moved and stored in the inner blade 15 within the contour of otsypannoy Zachodni a, b, C, ,

Moldboard 5 running rotary platform is set so that the maximum height of the mast 6 was located in the direction of movement of the bucket 12 along the upper transverse edge otsypannoy Zachodni a, b, C, d (2, 3). When the bucket 12 picks up a rock from the bottom to the top part of the collapse of the blasted overburden 27 in the upper part otsypannoy Zachodni a, b, C, d inner blade 15 (2, 4). The mast 7 is located in the direction of movement of the bucket 13 of average height part of the collapse of the blasted overburden 27 average height part otsypannoy Zachodni a, b, C, D. the Mast 8 is located in the direction of movement of the bucket 14 from the upper part of the collapse of the blasted overburden 27 in the lower height portion otsypannoy Zachodni a, b, C, D. Thus, a direct result of the storage buckets 12, 13, 14 all adipoma in section breed is evenly distributed along the length of the slope of the inner blade 15. The whole rocks in the upper part of the interior of the shaft 15 is eliminated. In the upper part of the inner blade rises only 25-30% of the entire breed. This results in reduced consumption of energy and materials.

When deriving the buckets 12, 13, 14 are moved parallel passages, leaving between them breed in the ridges (figure 5). These rock ridges 26 excaberate buckets 12 or 13 after the next move bucket Stripping unit the value of the step advancing. This eliminates the necessity of returning the unit for cleaning of the rock ridges 26 or to attract small-sized equipment. The result is improved performance.

Productivity increases as a result of the fact that the decrease in the height of the match reduces weight specific ground pressure and increases the permeability of the Stripping wheel Assembly.

In addition to the technical result, productivity increases several times by increasing the number of buckets. This is an unexpected result in the creation of cable excavators.

The originality of the invention lies in the fact that the increase in performance bucket Stripping unit, reducing the consumption of energy and materials is achieved by reducing the height of the mast in the direction of inclination of the slope of the inner blade.
