Known Executive body of the mining machine, comprising a housing in the form of a drive pulley and mounted on the outer side surface of the drum instrumentalization, each of which is placed with the possibility of replacing destructive tool [1]

Analysis of the loading of the cutting drum shows that the amount of torque on the shaft of the drum varies during rotation of the drum around its longitudinal axis, which lead to reduction of the durability and reliability of work of the Executive body and its drive due to non-uniform changes in the magnitude of the torque on the shaft of the drum. The necessity of calculating the Executive body working at peak time leads to the increase in material consumption as the Executive body and its drive.

Closest to the present invention is the Executive body of the device for destruction of mineral environments and artificial materials, which includes a housing in the form when erately, each of which is installed with the possibility of replacing destructive tool [2]

As studies have shown, depending on the mode of operation of the Executive body of the torque on the shaft of the drum in one of its turnover varies from 1.3 to 1.5, which has a negative influence on the dynamic loading of the cutter drive. Additionally, this uneven loading of the cutter drum reduces the durability and reliability of work of the Executive body, especially when the fracture of heterogeneous materials or rocks with hard inclusions. These drawbacks are caused by irrational parameters of the scheme of arrangement destructive tools on the drum.

The purpose of the invention to increase the durability and reliability of work of the Executive body by reducing uneven torque on the shaft of the Executive body by optimizing the arrangement scheme of destructive tools.

The objective is achieved by the fact that the Executive authority for the destruction of the mineral environments and artificial materials, comprising a housing in the form of a drive drum of cylindrical shape and is fixed on the outer side surface of the NT, on each half of the drum, which is formed by the corresponding end of the drum and the plane perpendicular to the longitudinal axis of symmetry of the drum and passing through the transverse axis of symmetry of the latter, destructive tools are deployed on two dvuhmetrovym helical paths which are offset relative to each other along the perimeter of the drum, and each helical path posted by an odd number of destructive tools, thus destroying the instruments in each helical path set with constant linear and angular step and offset from the destructive tools that are in adjacent helical path on the corresponding half of the drum, by an amount equal to half of the linear step, and located respectively at the start and end points of each helical path of destructive tools hosted on the same line, which is parallel to the longitudinal axis of symmetry of the drum, and a helical path, which are located on one half of the drum, have the counter wrapped in relation to helical paths, which are located on the other half of the drum, and a destructive tool, which is located at the starting point of one of vintge tool on the other half of the drum at the starting point of the corresponding helical path at an angle of not less than 50aboutand not more than 75about.

Besides the fact that located on one half of the drum helical path shifted relative to each other along the perimeter of the drum by an angle equal to 180about.

In the study of science and technology in this and related fields detected by the Executive body for milling various coatings, which comprises a drive drum of cylindrical shape and is placed on the outer lateral surface of the drum holder with destructive tools, thus destroying the instruments are located on the outer surface of the drum in helical paths (lines) that form located on the transverse axis of symmetry of the drum Chevron (application France N 2459329, CL E 21 27/24, 1981). In a well-known Executive body of destructive instruments placed on the outer surface of the drive pulley symmetrically relative to the transverse axis of symmetry of the latter. However, as shown by comparative tests, such symmetrical circuit arrangement destructive tools for cutting acaemy technical result will be worse in comparison with the declared design of the Executive body.

In Fig.1 shows a diagram of the digging machine with the Executive body of Fig.2 scheme of road cutters with the Executive body of Fig.3 scheme of the Executive body, the cross-section of Fig.4 is the same, General view; Fig.5 detailed setup diagram destructive tools on the outer side surface of the drum.

The Executive body of the device for destruction of mineral environments and artificial materials includes a housing in the form of a drum 1 has a cylindrical shape. The drum 1 is mounted for rotation around its longitudinal axis 2 symmetry on the supports 3. Support 3 can be located, for example, at the free end of the arm 4 the digging machine (Fig.1) or on the frame 5 road cutters (Fig.2). The drive of the drum 1 can be made from placed in the internal cavity of the drum 1 of the engine 6, for example, hydraulic (Fig.1) or located on the frame 5 of the engine 6, for example, an electric motor (Fig.2), the output shaft is kinematically connected with the shaft 7 of the drum 1. On the outer lateral surface of the drum 1 is fixed instrumentalization 8, which can be connected to the drum 1 by means of detachable or permanent connection. Each instrumentalization 8 fitted eroplano insert 10. As a destructive tool 9 can be used radial or tangential coal cutters and roadheaders or cutting tool for plow systems. Destructive tool 9 is installed in instrumentalization 8 can be replaced when they break or wear its cutting part, that is destructive tool 9 is connected with the corresponding instrumentalization 8 by means of detachable connections. On each half of the drum 1, which is formed by the corresponding end of the drum 1 and the plane perpendicular to the longitudinal axis 2 of symmetry of the drum 1 and passing through the transverse axis 11 of symmetry of the drum 1, the destructive tools 9 placed on two dvuhmetrovym helical paths (lines), respectively 12 and 13 on one half of the drum 1 and, respectively, 14 and 15 on the other half of the drum 1. A spiral trajectory 12 is displaced relative to the helical path 13 along the perimeter of the drum 1 at a certain angle, and a spiral trajectory 14 is displaced relative to the helical path 15 along the perimeter of the drum 1 at a certain angle. As studies have shown, the most appropriate is the offset relative to each other located on one half of bacteri 14 and 15 by an angle equal 180about. In each helical path 12, 13, 14 and 15 posted by an odd number of destructive tools 9. For example, in each helical path 12, 13, 14 and 15 (Fig.5) there are seven destructive tools 9. Destructive tools 9 in each helical path 12, 13, 14 and 15 are installed with a constant linear step tLin(Fig.5) and with a constant angular step tUHL(Fig.3 and 5). Destructive tools 9, which are arranged along a helical path 12, offset from the destructive tools 9, which is installed along a helical path 13, by an amount equal to half of the linear step, i.e. by 0.5 tLin(Fig. 5), and destructive tools 9, which are arranged along a helical path 14 that is offset from the destructive tools 9, which are arranged along a helical path 15, an amount equal to half of the linear step, i.e. by 0.5 tLin(Fig.5). Such arrangement of the cutting tools 9 provides chess (cell) scheme destruction of the face. Destructive tool 9, which is located at the starting point 16 (Fig.5) of each helical path 12, 13, 14 or 15, is located on one straight line, which is parallel to the longitudinal axis 2 of the drum 1, with destructive tool 9, cot, located on one half of the drum 1 have opposite winding relative to the screw trajectories 14 and 15, which are located on the other half of the drum 1. Destructive tool 9, which is located at the starting point of 16 helical path 12, is displaced along the perimeter of the drum 1 is relatively destructive tool 9, which is located at the starting point of 16 helical path 15, the angle , the value of which is not less than 50aboutand not more than 75about.

The handle 4 the digging machine (Fig.1) pivotally connected to the housing 18 of the combine and set to rotate in a vertical plane by means of the hydraulic cylinder 19. The housing 18 of the harvester is mounted with a possibility of rotation in the horizontal plane relative to the frame 20 of the chassis 21 of the combine.

Rama 5 road cutters (Fig.5) are mounted on the chassis 21 of the cutter and connected to the traction mechanism 22, such as a tractor. Frame 5 cutters mounted for movement in a vertical plane together with the Executive authority by the feeding mechanism (not shown), which may be performed, for example, in the form of a hydraulic cylinder.

The Executive body of the device for destruction mineralnych engine 6, which results in rotation around its longitudinal axis 2 of the symmetry of the drum 1. Then submit the drum 1 in the direction of destructible material. In the use case of the Executive body on the tunneling harvester (Fig.1) the specified movement of the drum 1 is carried out by switching on the drive chassis 21 of the harvester. In the case of use of the Executive body on a road milling cutter (Fig.2) the supply drum 1 in the direction of erodible material (bottom) perform switching of the feeding mechanism by means of which the frame 5 together with the rotating drum 1 is moved down in the vertical plane of Movement of the rotating drum 1 in the direction of destructible material is carried out until the desired depth milling, that is, until the penetration of destructive tools 9 in erodible material at a certain depth (the thickness of the chip). When interacting with erodible material (rock or artificial road surface) destructive tools 9 rotates together with the drum 1 around its longitudinal axis 2 symmetry, impact on destructible material and form in it the furrow cuts. When the cutting surface is usually formed "collapse" when the furrow cut wider in front of the ol. The balance of destructive tools 9 on the side surface of the drum 1 implements chess (cell) type of cut, which is a type of serial re-type cutting. In such a scheme of arrangement destructive tools 9 even cuts, interspersed with the odd, carried by Telicka a height equal to half the thickness of the chip. After penetration of the drum 1 to a predetermined depth perform linear movement of a rotating drum 1 at the bottom. In the use case of the Executive body on the tunneling harvester (Fig.1) the specified movement of the drum 1 at the bottom perform sequential or simultaneous rotation of the handle 4 relative to the housing 18 of the harvester with the help of the hydraulic cylinder 19 and the rotation of the housing 18 of the harvester with respect to the frame 20 of the chassis 21 of the harvester. In the case of use of the Executive body on a road milling cutter (Fig.2) linear moving rotating drum 1 is carried out using a traction mechanism 22, which is connected to the chassis 21 road cutters. After the destruction of the material on the whole surface of the face, if necessary, repeat the movement of a rotating drum 1 in the direction to destroy the mother is bigatel 6 and the Executive body of the lead into the transport position. In the process, produce, as necessary, replacement of worn or defective destructive tools 9 by installing the new destructive tools 9 in the appropriate instrumentalization 8. In the process of destruction of material to destructive tools 9 can be made of the flow of the operating fluid (not shown) for cooling destructive tools 9 and dust suppression.

The use of the Executive body of the claimed design will increase the durability and reliability by reducing uneven torque on the shaft of the cutting drum. This reduces the uneven loading of the cutter drive that allows you to reduce the output of the drive motor and, therefore, reduce the energy intensity of the process of destruction.
