The invention relates to the mining industry and is designed for mechanization of mining excavation and mining.

Famous mountain harvester.with. USSR N 1712599, publ. 1992), where blasting, loading and delivering combined in one process from one drive by performing only arrows harvester in the form of a pipe with an air body in the form of a screw cutter, the front end of which is equipped snecky harvester is the traditional way in particular conveyor, the use of which eliminates the universal application of the mining combine, limits its scope to angles of output. Screw cutter and screw the bumper body, placed in the pipe boom alternating between sliding plates, have limited scope for the destruction of solid rock, loading and transportation of rock mass. Not resolved the issue of dust suppression. Placement of the actuator coaxially in the end of the pipe causes the unloading of the rock mass only in the tray pipe - boom harvester. The combination of transportation and blasting through a common screw shaft does not provide advanced performance vehicles concerning the conditions, which complicates the breaking of rock mass due to accumulated smitten rock in the bottom output. Required idle movement of the working body only for loading of the rock mass. In General, the harvester has a limited scope, inefficient and designed for sinking and rescue channels, avoiding the use of hydropneumothorax.

Known Executive body of the digging machine. C. the USSR N 1726742, publ. 1992), where the reference node is executed in the form of a gear wheel, which Is the location of the reference node prevents the release of the rock mass along the auger to control vehicles. The rock mass is discharged within the face using a further known loading means, for example zagrebnyh paws.

The tubular bearing is used only as a base for the blades of the screw, located inside the housing of the screw, and one-piece drive shaft with zaborniak, while cutting the crown is zaborniak and provided with blades of the screw, which is placed on the outer surface and is made in the form of a separately recruited plates. Speakers console plates are made with cutting edge, equidistant to the slots in the housing of the screw. This embodiment Executive body has a narrow scope, only for the selective extraction of coal, and easily destroyed, because the spiral cutting edges must remove chips simultaneously throughout the spiral, which creates considerable efforts on cutting coal with ineffective breaking. Transfer the combined efforts of cutting, transporting only through solid Central shaft to create a critical load on the torsion shaft, which does not allow to seize the coal to a considerable depth, which determined the lowefficiency working body and when removing, for example, coal. Repulsed minerals (coal) comes ceranova working body until the arrow is discharged through a window on the sweeper mechanism. The dust suppression issues are not resolved, precluded the use of hydropneumothorax. Thus, well-known Executive body of the digging machine has a limited scope, only for the selective extraction of minerals.

Known methods for removing soil circulating water flow (application Japan N 48-28216, publ. 1973) or by using compressed air (Japan's bid N 48-11625, publ. 1973).

The closest technical solution to offer is heading the unit N. G.Black (and.with. N 787640, Bull. N 46, 1980), including chipping and loading the body with the input Windows, the arrow of the Executive body with a Central hollow shaft and spaced actuators, rotary device of the Executive body and Assembly in the form of spheres, a movable body, which is made hollow in the form of a continuous series of hollow parts, equipped with gidrotransportirovanie devices in the form of hydrodemolition, spacer-walking mechanism of movement (prototype).

The disadvantage of this unit is that is zastupovanie a mass of rock series of hollow parts with gidrotransportirovanie devices within the unit, especially in the boot when complete the Xia, where possible, the use of traditional transport (pipeline, railcar, skip, bucket), which limits the scope of the unit as a whole.

The objective of the invention is to increase the efficiency gidropnevmosistemy device Assembly with different types of vehicles for mining with minimal dust, increasing the scope and completeness of loading from the bottom output.

To solve the problem of the universal and the drilling Assembly includes a pneumatic loading the body with the input Windows, the arrow of the Executive body with a Central hollow shaft and spaced actuators, rotary device of the Executive body and Assembly in the form of spherical supports, a movable body with a mechanism of movement, which is made hollow in the form of a continuous series of hollow parts with gidropnevmosistemy, with a continuous series of hollow parts with gidrotransportirovanie devices equipped with screw conveyor, the front section of which is located in the hollow Central shaft work and kick-loading body, rear drive section is located in the cavity of the movable body with the mechanism of movement, supply ode, and adjacent sections of a screw conveyor are interconnected in places of rotary devices of the Executive body and Assembly connections gook, located in the center of the spheres of rotary devices performing the function of rasstilalsya when hydropneumothorax or independent of a screw conveyor as a means of transport.

Outlet ports of the rolling body with the shifting mechanism is equipped with nozzles for connection with receivers of different transport and paleotsunami funds through the mine workings.

In the case of use of the unit with a loading device, for example, in the form of a receiving table with the sweeper paws the front section of the screw conveyor located in the cavity of the Central shaft of the Executive body, provided with independent drive.

In Fig. 1 shows the proposed unit, side view; Fig. 2 - continuous miner, side view; Fig. 3 is a view in plan; Fig. 4 - the Executive body, type in the plan.

The unit (Fig. 1) consists of a pneumatic loading of the body 1 with an inlet 2 Windows, arrows 3 Executive body with a Central hollow shaft and spaced actuators 4, the rotary device in the form of spherical bearings 5, 6 run, , 10 pneumopericardium devices in the form of pneumohydraulic located in the cavities 9, 10 (not shown) with a supply of water or air through hydropneumoprivod 24, sectional screw conveyor 11, 12, 13, of which the front section is located in the boot portion 14, which in turn is located in the bumper-loading the body 1, the rear drive section 15 with the exhaust Windows 16 for the rock mass and 17 for collecting dust located in the movable body 7 in the case of use of the unit with the traditional transport, for example, telescopic belt conveyor, end of the cylinder 18 which is interconnected with the unit by the communication node 19.

When the mode of transportation of rock mass in mine workings air lines are used to supply air 20 and transportation of rock mass air 21 (shown conventionally).

When the mode of transportation of water used for mining supply line 22 (shown conventionally) and outlet 21.

The shaft sections of a screw conveyor 11, 12, 13 interconnected by connections gook 23 located in the center of the spheres of rotary devices 5 and 6.

Harvester (Fig. 2, 3, 4), for example, tracked mechanography body 1, the receiving table 26 with the sweeper legs, the frame 27 of the machine.

The Central cavity of the shaft of the Executive body, including the bumper-loading body, provided with a front section of a screw conveyor 11 with outlet box 16 and Autonomous drive 28. Screw conveyor passes inside the hollow Central shaft of the boom 3 and the housing 7 (Fig. 4). When combined chipping and loading the body with a screw conveyor and the receiving table sweeper paws unloading of the rock mass is on the Central conveyor 29.

The work of excavating unit with a screw conveyor and dust-extraction device is as follows. Included in the work of the screw conveyor with drive 15 (Fig. 1), in the boot portion 14 of the conveyor is loaded chipped and partially fragmented mountain mass, which is transported by sections of a screw conveyor to the outlet ports 16, where gravity is directed, for example, on the head end 18 of the conveyor located in the mine workings behind the unit, In particular, adopted a telescopic belt conveyor head end of which is interconnected with a movable case unit 7 moves together. The dust from the face along with rock mass is sucked through the inlet window 2 free from the rock mass, to the output window 17, which is connected to paleotsunami unit (not shown). Therefore, the rock mass and dust should be removed from further transported in open vehicles dust minimum, constructive gap between the screw of the screw conveyor and the housing provides free rough dust, which is collected as middlings.

The work of excavating unit pneumostransport, when the notch of the lower bumper strip-loading the body is fully immersed in the previously repulsed mountain mass, the entrance window 2 overlap, a vacuum is established in gidropnevmosistemy system, transportation by air is impossible in the hollow Central shaft of the Executive body, loading boot is part 14 of a screw conveyor with pneumatic loading body 1, in this case, a screw conveyer in hydropneumothorax functions rasstilalsya.

At mines where developed pneumonie, transportation of the rock mass is air, to the output window 16 of a screw conveyor connects the inlet 20 and outlet 21 pipelines, part of the air is directed into pnevmatikos the sa dust with this method of transportation closed. Pneumonectomy perform the function paliatsos and pneumatic together with a screw conveyor. In enterprises with transport instead of air is water, when gidroezhektorov unit also creates a vacuum and suction coal and dust. Loading of the rock mass and transported to the vehicles is similar to the output Windows connect the water inlet 22 and outlet water from the mountain mass (suspension) 21 pipelines. Dust is localized first hidroelektra in the cavity 9 and soaked deposited, transported together with the mountain mass.

Combine with a loading device (Fig. 2, 3, 4) is as follows.

Pneumatic loading body 1 is moved in the vertical and horizontal plane along the face, destroying, breaking into an array by loading part of the smitten rock mass through the input window on the screw conveyor, which transports the rock mass to the outlet port 16, then at the centrally located conveyor 29. The main part of the bumper of the rock mass is loaded nagranie paws within their technical capabilities. At extreme angles of production is hampered loading of the rock mass from the bottom up through the suction table 26 to shovel the ssy is the bumper-loading body and transported by a screw conveyor to the loading on the horizontal part of the scraper conveyor on the frame of the harvester or directly in control of the vehicle. Smitten the rock mass outside the width of the receiving table is selected from the sides of the framing by filing a pneumatic loading the authority for the screw conveyor, including the pits for lining and drainage grooves.

While providing advanced performance for loading and transportation of rock mass with a screw conveyor relative to blasting working body there is no need to sweeper legs, in this case, the receiving table is used for Stripping of soil excavation, at small angles of carrying out production in the receiving table and the Central conveyor eliminates the need and functions of transportation performs screw conveyor to known transport control means.

Thus, the swept equipment working bodies, rock-loading bodies in complex with a screw conveyor increases the scope of application of the known harvesters on the angles of the production from top to bottom, provides Stripping the soil of its boards, outside of the receiving table, ensures the discharge of the pulp produced by the stop face and the accumulation of water (when the drilling is carried out from top to bottom in flooded soils), there is a possibility for now produced Sereny table to use for Stripping of soil production, the direction of the rock mass at the centrally located conveyor and as the basis for the sustainability of the harvester.

Equipment sinking aggregates with pneumomediastinum devices screw conveyor, consisting of sections connected by joints gook, will ensure smooth transportation of rock mass, will increase the efficiency of loading and expand the scope of using different types of transport for mining.
