The movable part is connected to the housing transfer gearbox by means of a hinge mounted hydraulic cylinders and parallel to the axis of rotation of the transfer gear. The axis of the hinge connection of the parts of the handle are parallel to the axes of rotation of the shafts of the cutting disks. 3 Il. The invention relates to mining equipment, in particular, to the mechanization of the tunnel and sewage treatment works.Known Executive bodies harvesters of the type "Karaganda-7/15" and "Ural-XA" [1, pp. 58-68] containing the main shaft rotation, drove portable speed (transfer box), handle, cutting disks and sabunike. The disadvantage of these structures is the inability to process the entire cross-sectional area develop cutting discs. To do this, the harvester must have not only zaboric, but top striker device, and bemovie bodies.Known Executive body of the harvester Ural tarno-disk body includes a transfer gear, which planet carrier attached to it on the sides, two handles, containing serially connected cylindrical gear wheels and cutting discs mounted on the output shafts of the handles in the same vertical plane, perpendicular to the plane of the face, and making a planetary movement about the axis of rotation of the transfer gear. The disadvantage of the prototype is the inability to process the entire cross-sectional area produce only cutting discs.The aim of the invention is the enhanced operational capabilities of the Executive body.This objective is achieved in that in the Executive body of the digging machine, comprising a transfer gear housing and the drive and secured on the sides of the two handles, which are arranged symmetrically with respect to the axis of rotation transfer gear connected in series and containing a cylindrical gear wheels and cutting discs mounted on the output shafts of the handles in the same vertical plane, perpendicular to the plane of the face, each handle is made of two pivotally interconnected movable and fixed parts, while the fixed part is the exploits hinged hydraulic cylinders and parallel to the axis of rotation of the transfer gear, and the axis of the hinge connection of the parts of the handle are parallel to the axes of rotation of the shafts of the cutting disks.Execution of handles integral with the possibility of rotation of the moving parts are relatively fixed with hydraulic jacks, distinguishes the proposed structure of the Executive body known as providing processing of the entire cross-sectional area production without additional cutting devices.In Fig. 1 shows the location of the Executive body of the harvester in the transverse plane generation (view from the side of the combine to the slaughter), Fig. 2 - the same, in the longitudinal plane generation (body side), and Fig. 3 - position dual Executive bodies combine in passable develop a larger cross-section (view from the side of the combine to the bottom) showing plots of the cross section for the production, handled cutting discs Executive bodies. The Executive body of the digging machine includes a transfer box 1 with the housing and actuator. In the case of distributing gear 1, which is made to rotate with the portable speed relative to the axis 2, on the sides rigidly mounted symmetrically located relative to the OS is and drawings not shown). With no moving parts 3 and 4 of handles connected to movable parts 5 and 6 of the handles to rotate them relative to the fixed parts 3 and 4 of the hinges 7 and 8, the axes of which are parallel to the axes of rotation of the shafts of the cutting disks. Movable parts 5 and 6 of the handles are parallel to the axis 2 of the portable rotation transfer gear 1 and also contain consistently connected bevel gears, which are not shown. Movable parts 5 and 6 of handles connected to the housing transfer case gear 1 and, therefore, with no moving parts 3 and 4 of the handles by means of a hinge mounted hydraulic cylinders 9 and 10. On the output shafts 11 and 12 moving parts 5 and 6 of handles mounted blades 13 and 14, located in the same vertical plane, perpendicular to the plane of the face 15. The cutting discs 13 and 14 are made with the possibility of rotation of the output shafts 11 and 12 with a relative speed in opposite directions (see arrows in the drawings). Cutting tools disks 13 and 14 can be located on their periphery (see Fig. 1 and 2) and with their end surfaces (not shown). A circular cross-section generation is limited by the line 16. Area (areas) of popery 18. Vertical and horizontal axis of symmetry round production marked the positions 19 and 20. Position 21 marked rock core from the Central part of the production. Area (areas) of the cross section for the production, handled by the Executive body at the roof marked position 22. Position 23 designates a possible inclined position of the processing lines generation profile from its roof.We offer you planetary disk of the Executive body of the digging machine operates as follows.The cutting discs 13 and 14 with the tools, leaving the original position, make three types of motion: relative around the axes of their shafts 11 and 12, the portable around the axis 2 transfer gear 1 and the feed face 15 along axis 2 (see arrows in Fig. 2). When such movement of the tools cutting discs 13 and 14 Executive body produces skol rock from an open surface of the face serial sections and formed by the ledge (in the case of the installation tool with the ends of disks). As a result, when the source location of the movable parts 5 and 6 of the handles parallel to the axis 2 transfer gearbox 2 and not operating the hydraulic cylinders 9 and 10, there is formed a circular cross section generation, limited additional processing areas (plots) 17 and 18 of the cross-section, located at the soil on each side of the vertical axis 19 of the symmetry of the output. In this case, the cutting disk 14 with the movable part 6 of the handle and the hydraulic cylinder 10 remains in its original position and processes the vaulted part of the cross-section of its roof, and the cutting disk 13 with the movable part 5 of the handle, raise the rod hydraulic cylinder 9, the rotation transfer gear 1 about the axis 2 at 45ohandles right horizontal rectilinear portion 17 of the bottom soil production (see dotted image of the Executive body at its turn at 45ofrom the vertical axis 19 output). However, in case of continuous supply of the Executive body on the bottom 15 in the direction of the axis 2, the three above-mentioned movements of the cutting blade 13 is followed by a further rotary movement relative to the hinge 7, due to the rotation of the movable part 5 of the handle relative to the stationary 3, and the speed of the pull-out rod of the hydraulic cylinder 9 and, consequently, rotation of the movable part 5 of the handle with the blade 13 is consistent with the speed of a portable motion transfer gear 1. Upon further rotation of the transfer gear 1 45o90ofrom the axis 19, the piston rod of the hydraulic cylinder 9 extends in the cylinder, Knymi rectilinear portion of the bottom 17 of the soil excavation. After the turn of the Executive body on the 90othe cutting disk 13 will occupy its original position and in this position the further processes the vaulted part of the cross section generation. The cutting disk 14 at this time, when the rotating body from the horizontal axis 20 output 90otowards the soil, the mode control hydraulic cylinder 10 and, therefore, processing the left side 18 of the bottom soil production, and then processing all of her section. Also, as for the cutting disk 13 during the rotation of the body at 45othe piston rod of the hydraulic cylinder 10 extends and the disk 14 processes the left vertical rectilinear part of the face 18 at the soil production, and then, during further rotation of the body 45o90ofrom the axis 20, the piston rod of the hydraulic cylinder retracts in the cylinder and is processed in the left horizontal rectilinear portion 18 of the bottom soil excavation.Therefore, each cutting disc with its hydraulic cylinder on the steering angle body 90ohandles your Barmby plot of soil, and the rest of the rotation body 270ohandles round (cylindrical) part of the face. In principle, there are other possible timeline work of cutting disks 13 and 14 with hydrodams the 2 rotation transfer gear 1 is the most rational, because not only provides full processing Berkovich plots of the cross section generation, but the destruction formed in the Central part of the elaboration of the rock core 21.In the case of formation of a core 21 of its destruction is achieved by periodic lowering of the piston rods of the hydraulic cylinders 9 and 10 on the full value of their progress so that the movable parts 5 and 6 handles deviate from its original position, parallel to the axis 2 in the direction to the centre to develop only at a definite angle, and then again returned to its original position. The tools of the cutting disks 13 and 14 do not overlap with each other. When dual Executive bodies on the harvester may receive workings of large cross-section (see Fig. 3). But you must handle not only bemovie sections 17 and 18 of the cross section of its soil, as well as areas 22 at the roof. Processing sections 22 of the cross section of its roof (see also the dotted image lines 23 in Fig. 3) is cutting discs Executive bodies according to the above principle and the specific mission profile of each disk with its hydraulic cylinder. For example, in particular, one of the disks of each body can work in unregulated Reims mode controlled hydraulic jacks and processing Berkovich plots the development of its soil and the roof.Thus, the proposed design extends the capabilities of the Executive body of the digging machine, without requiring processing of slaughter additional special cutting devices in the form of Berkovich cutters, the upper bumper drums, sabourenkov. The proposed solution also provides the unification of the Executive bodies combine handles, spacers and the arrow type. The Executive body of the digging machine, comprising a transfer gear housing and the drive and secured on the sides of the two handles, which are arranged symmetrically with respect to the axis of rotation transfer gear connected in series and containing a cylindrical gear wheels and cutting discs mounted on the output shafts of the handles in the same vertical plane, perpendicular to the plane of the face, characterized in that, with the aim of enhancing operational capabilities, each handle is made of two pivotally interconnected movable and fixed parts, while the fixed part fixed to the body transfer gear, the movable part is connected to the housing transfer gearbox via a pivoting zakrepleniya the handle parallel to the axes of rotation of the shafts of the cutting disks.
