The invention relates to the field of mining engineering and can be used in the construction of mining machines.

Known Executive body of the harvester PC-9R (see kN. I. I. Of Basera, C. I. Kruchinina, Y. L. Sokolova. Tunneling machines. M.: Nedra, 1974 S. 112, 117), containing an arrow with a crown gear connected in a single whole frame, beams which can move the arrow with gear guide gear through cylinders telescope, completed design is its low efficiency and reliability due to the fact, that frame beams in this technical solution, in addition to cutting forces and the additional weight of the body is still active and the torque arising from the cylinders of the telescope as a result of their work. All this leads to intense wear beams and guide gear.

The closest technical solution adopted for the prototype, is the Executive body of the digging machine GPX (see Prospectus digging machine GPX, Glorikian S. H. and others Machinery and equipment for mines. - M.: Moscow state mining University, 1994, S. 25 g), including the boom with the crown gear with the guides, United into one, the frame having a beam, which moves in the guide gearbox arrow with the help of hydraulic cylinders telescope, located below the horizontal plane passing through the longitudinal axis of the beams.

The disadvantage of this technical solution is also low efficiency and reliability telescopic separation. Due to the fact that the beams and guides reducer force resulting from the torque generated by the cylinders of the telescope, which greatly exceeds the weight of the boom with gear and an additional force to the force of cutting, resulting from the work of ispolnitel beams.

The present invention is improving the reliability and efficiency of the Executive body.

In a well-known Executive body, including the boom with the crown gear with the drive frame containing beams placed in the guide gearbox two cylinder telescope connecting the frame with the gearbox installed parallel to the horizontal plane passing through the longitudinal axis of symmetry of the beams, cylinders telescope located diagonally on opposite sides of a horizontal plane with the formation of the shoulder with respect to a given plane.

Comparison of the claimed Executive authority with the prototype allows to make a conclusion about the absence in the latter of signs similar to a distinctive signs with the claimed Executive authority.

The cylinders telescope located diagonally on opposite sides of a horizontal plane with the formation of the shoulder with respect to a given plane.

The set of features of the proposed technical solution is different from the prototype and known analogues and should not be explicitly studied the prior art, therefore, the authors believe that object, that combination of traits, namely cylinders telescope located diagonally on opposite sides of a horizontal plane with the formation of the shoulder with respect to a given plane, solves the problem of the invention: improving the reliability and efficiency of the Executive body.

These characteristics are related to each other so that when the removal of one of them disappears given by the invention of the technical result.

The invention also represents a step in the development of technology and is progressive, as it allows to increase the operational reliability and efficiency of the Executive body.

The Executive body, which claimed the invention may find wide application in the mining sector and other sectors of the economy, that is industrially applicable technical solution. The achievement of the technical result, when the work of the Executive authority is ensured by the fact that the cylinders telescope located diagonally on opposite sides of a horizontal plane with the formation of the shoulder with respect to a given plane.

This solution allows to increase the telescope is located diagonally on opposite sides of a horizontal plane with the formation of the shoulder with respect to a given plane.

This design allows during operation of the telescope Executive body significantly reduce the load on the beams of the frame and guides the gears. This is due to the fact that the moments arising from the cylinders of the telescope in this design, act toward each other, thereby compensating for each other, changing the shoulders of the cylinders of the telescope relative to the horizontal plane passing through the longitudinal axis of symmetry of the beams, it is possible to compensate the action of the weight of the boom and gear. Thereby significantly reduce the forces acting on the beams of the frame and guides the gearbox, and to increase the operational reliability and efficiency of the Executive body.

The essence of the invention is illustrated the accompanying drawings.

In the drawings shows:

Fig. 1 - General view of the Executive body (side view);

Fig. 2 is a cross section of the Executive body (Sech. A-A).

The Executive body contains (Fig. 1, 2) arrow 1 crown 2, gear 3 with the actuator 4, a frame 5, a beam 6, is placed in the guides 7 of the gearbox 3, two cylinder 8 telescope connecting frame 5 with gear 3 and installed parallel to the horizontal plane of the bone "B".

The work of the Executive body are carried out as follows ( Fig. 1, 2).

Pressure builds in the cylinder 8 telescope with extension boom 1 with the crown 2 and gear 3 driven 4 together in the guides 7 relative to the beams 6.

Due to the fact that the cylinders 8 telescope installed diagonally and on opposite sides of the horizontal plane "B" with the formation of the shoulder "l" and "l1" is the compensation of the forces resulting from the torque action arising from the cylinders 8 of the telescope and directed towards each other, thereby greatly reducing the load on the beams 6 and guide 7.

We offer Executive body by the arrangement of the cylinders telescope diagonally and on opposite sides of a horizontal plane passing through the longitudinal axis of symmetry of the beams with the formation of the shoulder with respect to a given plane, allows to increase the operational reliability and efficiency of the Executive body.

Executive body, including the boom with the crown gear with the drive frame containing beams placed in the guide gearbox two cylinder telescope, soedineniya beams, characterized in that the cylinders telescope located diagonally on opposite sides of a horizontal plane with the formation of the shoulder with respect to a given plane.
