Description

one

The invention is intended for use in the mining industry.

Known tunneling machines, including a feeder, a loading body, a frame and two articulated arrow-shaped executive body, equipped with crowns with cones.

The proposed harvester is characterized in that the booms of the executive bodies are provided with a cross bar, hinged on the shaft, which coincides with the axis of the combine, and the axes of the hinges of the bodies are perpendicular to the shaft axis.

This embodiment increases the efficiency of development of the slab with selective excavation without the preparation of niches.

FIG. 1 shows the proposed combine, front view; in fig. 2 - the same, side view; in fig. 3 - kinematic scheme; in fig. 4 - order of processing of the bottom arch shape.

The mining machine includes two swept actuators 1, hinged on axles 2 and swinging around them using hydraulic jacks 3. Actuators of actuators are driven by electric motor 4. Actuators are mounted on traverse 5 fixed on horizontal shaft 6 by means of hinge 7, the axis of which is perpendicular to the shaft 6 and wasps m 2. Swing traverse 5 relative to the hinge

7 is carried out by a hydraulic jack 8, and the swing of the horizontal shaft 6 by a hydraulic jack with a rail 9. During operation, the combine is spread between the roof and the soil by overlapping 10 and the hydraulic jack 11. When the machines are fed to the bottom, the hydraulic jack 11

is removed, and with the help of a hydraulic jack shifter 12, the combine is fed to the bottom.

8 this moment the combine is distributed into the walls of the mine with the help of plates 13 and horizontal jacks of the spacer trolley 14,

relative to which the combine moves. In the initial position, the crowns are located at the sole in the middle part of the excavation. In this position, the combine is driven to the bottom by the amount of the N inlet, and the crown is not in contact with the face. Then, by means of a hydraulic cylinder 8, the plunging into the bottom occurs to a position where the crowns are in the coal seam (the seals are mounted on the seam with a hydraulic cylinder with a rail 9). With the help of hydraulic jacks 3, coal is excavated (dilution of organs). Then, by swinging the shaft 6 at an angle of 180 ° and spreading out the actuators of the actuators relative to the axles 2, the generation

round shape. By turning the organ downward with respect to the hinge 7, we get the berms, after which the crowns are brought back to their original position, and the cycle repeats.

Thus, the presence of the hinges 2 and 7 in the actuator, in combination with turns around the horizontal shaft 6, enables the crowns with the cones to move away from the slab by an amount greater than H and ensures the combine is fed forward without a notch.

When lifting the yoke, a smooth cutting of the executive body is provided for working out a new ledge.

Subject invention

The mining machine, which includes a feeder, a loading body, a frame and two articulated arrow-shaped executive bodies, equipped with cones with cones, characterized in that, in order to increase the development efficiency of a selective excavation without preparing niches, the arrows of the executive bodies are connected by a traverse, hinged on the shaft, which coincides with the longitudinal axis of the combine, and the axis of the hinges of rotation of the bodies are perpendicular to the axis of the shaft.
