The invention relates to mining and is designed to work with a loading machine of continuous or cyclical actions when carrying out excavations brown-and-blast method and overload rock from the tunnel face on a belt or scraper transport conveyor placed in the ongoing development, as well as for the formation of the blade destroyed by the breaking of rock or coal array.

When conducting mining brown-explosive way in the process of blasting rock or OTDELENIE pieces of rocks can be thrown to a distance of 20 m, as a result, it is necessary to carry out manual cleaning formulation.

When unloading of the rock mass from the bottom loading machines continuous, and especially cyclic actions (bucket) in the initial stage of loading their performance is quite low. This is due to the fact that the blade in the beginning has a small thickness of the layer, resulting in additional time spent on maneuvers with loading an organ or the whole machine.

In this regard there is an urgent need to develop special equipment or devices that allows you to shape the blade destructible rock mass and partially or completely overlapping section of excavation to correct dispersion of the rocks.

Considering the device is designed for receiving and transporting the thump of hands by the explosion of the upper stratum of ore. This feeder is a tray for receiving the thump of hands ore and is equipped with a vibrator for feeding n is yrbook, because it is not able to accept destroyed by the explosion of the rock mass from the breast of the face and does not allow to form the blade.

The closest in performance vehicles and loading functions is a device for release and loading ore [2] the Device consists of a vibrating conveyor, vibrating feeder, capable of moving along the conveyor through the hotel winch, frame with sliding perekryvatel and hydraulic stud jacks. The device is designed to control the release of previously repulsed ore through hesinki, rays or other rising output conveyor located in a horizontal development. To reduce the pressure of the efforts in the implementation of the feeder in a stack of ores it has a wedge-boot-toe with swivel plate.

Consider the device cannot be used to form the pile (pile) when blasting blasting the chest of the face in the process of conducting horizontal and inclined mine workings. It is intended for special conditions inherent in the mining industry, the issue of pre-broken ore through the rising generation with subsequent loading on the main conveyor.

The aim is achieved in that the downhole loader is located along the axis of the ongoing excavation and includes a conveyor with a rigid rod, located on the front end of the conveyor and connected with him toe wedge for the introduction of a pile of rocks and protection transport authority pipeline from direct impact of rock during blasting blasting and enclosing shields, the conveyor is made attached to the bottom side of the rod on the front of the base plate. Each enclosing shield, located on the corresponding side of the base plate, hinged to the support plate and is mounted with limited rotation in a vertical plane and fixing in position to partially overlap the lower part of the section held mine workings.

Downhole material handler has a mechanism to rotate the enclosing shields in the form of hydraulic power cylinders and retaining the at one end with the corresponding enclosing a shield.

Significant differences are as follows.

Downhole tailpiece with mounted on the front end of the conveyor toe wedge is made with a fixed on the lower side of the rod on the front of the base plate, the sides of which are enclosing shields, pivotally connected to the support plate with the possibility of limited rotation in a vertical plane and fixing in position to partially overlap the lower part of the cross section of the ongoing excavation. The cross section above the loader remains open, allowing the explosive blasting not only to form the blade of the rock mass, but also to place some part of it on the panline the composition of the pipeline.

For the implementation of a limited turning circle enclosing shields the material handler is a mechanism made in the form of hydraulic power cylinders, and a retaining rack for fixing cladding panels in position. Each retaining hour one end pivotally connected to the enclosing shield.
