The invention relates to mining and tunneling equipment, namely, drilling machines, intended for carrying out horizontal and inclined mine workings. The problem solved by this invention is to increase the productivity of the harvester through increased stability and easy manoeuvrability. Heading-Shearer, includes swept the working body, the body in the form of a welded frame construction, a pumping station with a system of hydraulic blocks, anchor skis are parallel to the longitudinal from the harvester, equipped with anchor blades, mounted in the front and rear housing parts, consisting of moving parts and is made to rotate in a vertical plane by means of hydraulic jacks rotation, one end of which is fastened to the supporting knives, and the other on the body of the harvester. The reciprocating movement of the skis relative to the transverse axis of the harvester is provided by a hydraulic cylinder mounted between the movable elements of the reference blade. Supporting the knives made in the shape of a closed four-hinge mechanism. 2 Il.

The invention relates to mountain-probodh mining.

Known continuous miner (ed. St. USSR N 294939 BI N7, 1971), including the Executive body, frame, chassis in the form of a ski covering their floaters power cylinders.

The disadvantage of this harvester is insufficient efficiency of the harvester, which is a consequence of the lack of stability.

The closest technical solution adopted by us for the prototype is continuous miner (ed. St. USSR N 899981 M CL.3E 21 D 9/10 BI N3, 1982), including the Executive body, the body with the supporting surface, the supporting skis are parallel to the longitudinal axis of the harvester and transported by means of a power cylinder connected with the supporting device and the frame, which in turn is connected by means of vertical cylinders with the control room.

The disadvantages of this combine are: lack of efficiency resulting from a lack of sustainability in the development of slaughter, because the stability of this harvester depends on the frictional forces arising between the support surfaces and soil; lack of maneuverability, to maneuver in a specified direction of the harvester spends considerable time due to many>/P>The problem solved by this invention is to increase the productivity of the harvester through increased stability and easy manoeuvrability.

This problem is solved due to the fact that the tunneling-Shearer, includes swept the working body, the body in the form of a welded frame construction, a pumping station with a system of hydraulic blocks, anchor skis are parallel to the longitudinal axis of the harvester, equipped with anchor blades, mounted in the front and rear housing parts, consisting of moving parts and is made to rotate in a vertical plane by means of hydraulic jacks rotation, one end of which is fixed on the supporting knives, and the other on the body of the harvester, and the reciprocating movement of the knife relative to the transverse axis of the harvester is provided by means of hydraulic jacks, installed between the movable elements of the reference knife, while supporting the knives made in the shape of a closed four-hinge mechanism.

Indeed, the stability of the harvester when a failover bottom is strengthened by the support of knives, one of which is buried in the ground.

To reduce the time on the man who, for example, a hydraulic cylinder connected to the machine body and with a specific ski or with a certain knife. In addition, thanks to the support knives, made in the shape of a closed four-hinge mechanism, the harvester can move relative to the transverse axis of the harvester. Gidrotartrat, installed between the movable elements of a knife, contributes to this reciprocating movement.

Comparative analysis with the prototype shows that the claimed continuous miner differs from the prototype to the presence of the support blades in the form of four closed hinge mechanism that improves performance. The harvester had the opportunity to move parallel to its transverse axis.

Thus, the claimed continuous miner meets the criteria of the invention of "novelty."

The comparison of the proposed technical solutions not only prototype, but also with other technical solutions are not allowed to reveal in them the features distinguishing the claimed invention from the prototype, which allows to conclude that the criterion of "substantial differences".

The invention is illustrated in the drawing, where Fig. 1 shows obshirny body 1; case 2 with reference skis 3 and 4 arranged parallel to the longitudinal axis of the harvester and transported by means of the power cylinders 5 and 6, the casing of which is connected to the ski, and the rod with the housing 2 of the harvester; supporting the knives 7 and 8, mounted in the front and rear housing parts 2, consisting of movable elements, made in the shape of a closed four-hinge mechanism. The front support of the knife 7 and 8 rear hinges 9 and 10 and the hydraulic jacks 11 and 12 is connected to the housing 2, between the moving elements of the support blades installed the jacks 13 and 14 to move the movable elements.

Continuous miner works as follows.

Case 2 combine their supporting skis 3 and 4 rests on the ground, while supporting the knives 7 and 8 only touch the soil.

Hydraulic power cylinders 5 and 6, the housing 2 is moved forward, while the Executive body 1 surubaya in the bottom breast. Then case 2 of the harvester lifted to support the knives 7 and 8 by rotating them around the hinges 9 and 10 by means of hydraulic jacks 11 and 12. Supporting the blades dig into the soil. In this position, is the practice of slaughtering the Executive body 1.

For reciprocating movement kornikova four-link mechanism to the right or left parallel to the transverse axis of the harvester, using a hydraulic Jack 11 and 12 supporting the blades are lifted, the hinge mechanism is shifted in the desired direction, and then reference the knives 7 and 8 are again omitted.

To move the harvester along the longitudinal axis of the harvester are the skis 3 and 4 and the power cylinders 5 and 6.

Due to the presence of reference of the knives 7 and 8 of the claimed continuous miner can turn on the spot.

Thus, thanks to the support of the knives 7 and 8 significantly increases the stability of the harvester with the development of the face and its maneuverability, which ultimately affect the performance of the harvester.

Heading-Shearer, includes swept the working body, the body in the form of a welded frame construction, a pumping station with a system of hydraulic blocks, anchor skis are parallel to the longitudinal axis of the harvester, wherein the harvester is equipped with anchor blades, mounted in the front and rear housing parts, consisting of moving parts and is made to rotate in a vertical plane by means of hydraulic jacks rotation, one end of which is fixed on the supporting knives, and the other on the body of the harvester, and a reciprocating perenesennymi elements supporting the knife, while supporting the knives made in the shape of a closed four-hinge mechanism.
