Description

The invention relates to mining combines for carrying out horizontal and inclined workings.

Known tunneling machines, including tracked, loading device, conveyor, frame and the executive body in the form of an arrow with a recessing crown, drive, lifting and turning mechanisms.

The proposed combine is characterized in that the actuator is mounted on a platform associated with the frame by a hinge and a jack, the boom swinging mechanism being located between the hinge and the lifting mechanism.

This embodiment improves the setting of the position of the cutting crown during selective recess.

FIG. 1 shows the proposed combine, side; in fig. 2 - the same plan view; in fig. 3 is a kinematic diagram of the combine, side view; in fig. 4 - the same plan view.

The proposed roadheader includes a crawler track /, the frame 2, the loading device 3, the conveyor 4, the executive body in the form of an arrow 5 with a cutting crown 6, the drive 7 and the mechanisms of rotation and lifting.

The actuator is mounted on platform 8, connected to frame 2 by joint 9 and jacks 10.

The rotation mechanism of the boom 5, consisting of

The axes // fixed on the platform 8, the body 12 and the jacks 13 connecting the platform 3 and the body 12 are located on the platform 8 between the joint 9 and the field, with the boom lifting mechanism M.

The boom lifting mechanism consists of a joint between the sub-earth formed by the trunnions fixedly mounted on the boom and entering into the corresponding openings of the casing 12 of the turning mechanism, and jacks 15 connecting the boom 5 and the casing of the turning mechanism 12.

The combine works as follows.

Cutting box | Nka 6 drives to the bottom in a given place with the stationary combine from to. jacks 16. The position of the boom 5 when inserting the crown in the face is selected depending on the adopted pattern of working the bottom and on specific geological conditions by raising, lowering or turning the boom 5 with jacks 10, 13, 15.

The downhole processing is carried out with a cutting bit 6 when the boom 5 is moved with jacks 13 and 15 in horizontal or vertical directions.

As required, the distance from the soil of the development of the jib 14 of the boom raising mechanism is made by raising or lowering the platform 8 with the jacks 10. This operation is performed for the most effective (with the least loss) mining of felds during the selective excavation and also for irregularities and ledges on the roof and the soil of the ongoing development. The horn has been beaten off, the mass is removed from the working soil by the loading device 3 with scoring legs and with the help of the conveyor 4 it is reloaded into vehicles.

After processing the entire area, the dredger moves forward by the amount of the notch in the crown array 6, and the cycle is repeated.

Subject invention

A tunneling machine comprising a crawler track, a loading device, a caliper, a frame and an actuator in the form of an arrow with a cutting crown, drive, lifting and turning mechanisms, characterized in that, in order to improve the setting of the cutting crown position during selective excavation a platform connected to the frame with a shchi.riyr frame and a jack. Moreover, the boom swing mechanism is located between the hinge and the hoist mechanism.
