The invention relates to the mining industry and can be used mainly for loading rock mass on dump trucks in the implementation of continuous work surface miners.

A device for continuous loading of railway wagons mountain mass when working with the mining machine of continuous operation, comprising a frame on which are mounted rotatable funnel with the transfer sleeve and the valve material flow. In operation, the device is suspended from the conveyor the conveyor, for example, a rotary excavator [1].

This device has functional limitations to work with career harvesters and cannot be used to work with them.

Known self-propelled hopper for loading trucks [2]. Self-propelled hopper includes a portal to the road trucks, running bunker capacity of the valve, the loading device made in the form of a funnel. The material in the hoppers passes through the receiving funnel and open the shutter. When filling the hopper tank to the specified level, the sensor activates and the material flow is directed to the filling of the second bunker.

Self-propelled hopper has a large number of transmission mechanisms that limit the reliability of continuous operation of the structure.

Well-known boot is a device for loading of a dump truck and complex for loading dump trucks [3-4]. Boot device [3] contains a frame mounted on it, a hopper, a shutter with movable plates and the actuator for closing and opening. The opening of the shutter is carried out by exposure of the body of the truck on the bracket shutter, when driving the truck back, the body is filled with rocks. After filling out the body of the dump truck goes forward from under the boot device and the shutter is automatically closed. The boot device is self-propelled and moves from place to place on the sled.

The closest in technical essence is complex for loading dump trucks [4], which involves two identical boot module with the possibility of permutation and filing them in the rock mass by means of an excavator. Bins installed on the frames, the capacity of which corresponds to the capacity of the used trucks.

This complex is for loading dump trucks are not able to perform the task of loading rock mass during the continuous operation of the combine because of the design (no drive movement of the modules of the complex) and functional (automatic continuous following excavation machine) features of the complex, including the positioning of the bins relative to the boot device of the harvester. For the filling height of the boot device is tion will require increasing the length of standard conveyors career harvesters, that will lead to increase of weight, dimensions and cost harvesters [5]. When turning the console line from one of the load module to another will need to stop the combine, therefore, appears downtime and reduced productivity.

The technical result consists in increasing the technological efficiency of the complex, engaged in automatic mode the combination of processes of positioning one of the bins for loading the dump truck with the positioning of another hopper for loading with conveyor career harvester during the stroke of career combine with the provision of uninterrupted, without downtime functioning career harvester. Both bins are located in the same module, the sequential loading conveyor career combine the bins are lowered and the height of the top edge of the enable loading conveyor. The sequential unloading bins using hydromechanical raised, rotated and moved longitudinally, providing uniform loading dumptruck body.

The technical result is achieved in that in the method of loading rock mass on dump trucks, including the possibility of movement of the modules with bunkers and supply of rock mass in bins with a capacity corresponding to the capacity of COI is lsemaj trucks, the independent processes of positioning one of the bins for loading the dump truck with the positioning of another hopper under load, independent of the processes of positioning of bunkers occurs simultaneously with the process of career harvester in the automation of process orientation system for loading a relatively career harvester and truck is a relatively complex for loading, and the implementation of independent processes positioning of bunkers occurs by moving frames of bins in the vertical plane and carriages of the hopper in a horizontal plane and is controlled by mechanisms of vertical movement and horizontal movement mechanisms, and the bins by means of articulated links with carriages have the ability to rotate in a vertical plane with telescopic mechanisms of rotation, and the frame of the bunkers when you move enter into interaction through bearings with vertical guides.
