The invention relates to the mining industry, and is intended for overload rock on moving vehicles, such as pipeline digging machine, on a mobile loader and the loader on the vehicle through the mine workings without sifting of the rock mass on the soil production, regardless of mutually spaced funds.

Known points of handling pipeline digging machine, for example PU, PC-3M, CSR-1/1,2/, 4PPT-2 /3/, RSCC and other /2/ on the loader, attached to the harvester end of the cantilever part of the loader, remote from the point of entrance of the rock mass to the material handler.

This replenishment does not preclude spillage of the rock mass on the soil production at mutual angular offset of the conveyor harvester relative to the longitudinal axis of the loader, as the place of receipt of the rock mass on the loader shifts and part of the rock mass wakes up by a loader on the soil excavation. So it is heavy wear on-Board sheathing receptor material handler due to contact with the displaced rocks. The same occurs when the angular displacement of the loader relative to the longitudinal axis of the conveyor located in the mine workings (gathering conveyor) /4/.

Spillage especially increases in spreads combine for loading tbiti rock mass, when the width of the formulation is greater than the width as loading table combine and spread in the horizontal plane of the boom working body of the digging machine.

Proposed paragraph handling differs in that the fastening point of the rolling material handler to heading harvesting or gathering conveyor aligned with the contact of the rock mass, coming from the combine to the loader, with the loader on the gathering conveyor vehicle.

This embodiment eliminates the spillage of the rock mass on the soil production in paragraphs overload on the turns of the harvester in the downhole part of working with the aim of loading rock mass on the entire width of the face and blasting to the design width of the output.

1 shows a transshipment point from the combine to the loader;

figure 2 item handling (view a-a, figure 1);

figure 3 shows the point of reloading with a loader on gathering pipeline.

Item handling (figure 1) consists of a head end of the conveyor 1 digging machine or loader (figure 2) to the receiving end of the head 2 trailer mobile material handler or gate conveyor 3, is interconnected with the head end of the conveyor digging machine through the spherical hinge connection 4 (figure 1) or hinge in the form of a cylinder 4 cylinder 3 and the abutment crowns is tanov 5, Articulated spherical connection 4 and the shaft in the cylinder 4 located in the middle stream of the rock mass 6 in the region of contact of the material handler go face conveyor according to their axes of symmetry.

When conducting mining develop when the width is greater than the loading table of the harvester are loading rock mass to produce several benches of the processor to which the harvester deploy to the left as Board development and to the right, while the head end of the conveyor relative to the loader takes a different angular position about the axis of the conveyor in the horizontal plane, the same happens at the transshipment point with a loader on gathering pipeline.

When placing the attachment point in the center of the contact of the rock mass with loader and gate conveyor ensures the constancy of the contact areas of the flow of the rock mass on the loader, the same happens when the angular displacement of the loader relative to the gathering of vehicles.

Thus achieved the minimum spillage of the rock mass on the ground workings at almost normal receiving device spillage is eliminated, re-sweep generation is excluded, are the normal conditions of operation of vehicles and mining.

Item handling, such as a conveyor prohodke is one harvester, trailer mobile crane, turnbuckle on the console loader, characterized in that the fastening point hitch of the rolling material handler to tunneling processor combined with the contact of the rock mass, coming from the combine to the loader, the same with the loader on the gathering conveyor vehicle.
