Description

The invention relates to the mining industry and is intended for deserted coal mining in the development of thin layers.

Izvesia buroshnekovo installation, including osh drive, auger screw and zaburnk |||.

However, this installation is characterized by insufficient intensity of coal mining.

It is known a device for burochelkovy coal excavation, which includes two drilling machines with two screw augers installed in parallel with bu (New crowns and a cutting mechanism placed between riHMH with an actuator made in the form of a chain contour with working elements and connected with drive sprockets, with two screws staves that are located at the ends of the excavation mechanism from opposite epo sides with the possibility of extending one auger stav when trimming another | 2}.

The said device is also characterized by insufficient intensity and productivity of labor.

The aim of the invention is to increase the intensity of coal extraction and increase the productivity of labor.

This goal is achieved by the fact that a device for coal-boring excavation of coal includes two brown-screw installations with a parallel screw set with drill bits and an excavation mechanism placed between them with an executive body made in the form of a chain contour with working elements and connected with sprockets with two screw stacks, which are located at the ends of the excavation mechanism from its opposite sides with the possibility of lengthening one screw rod when shortened and the other, each auger drill bits stava arranged at their opposite ends.

FIG. 1 shows the proposed device, a general view ;, FIG. 2 shows section A-A in FIG. ; in fig. 3 - section .B-B in FIG. 2

The device consists of an executive body I, made in the form of two endless chains with working elements mounted on them, which separate coal from the rear sight and deliver it to auger ctaBaM 2, double-sided guide circuit 3, which is used for directional movement of the executive body and connected to shafts shnekovyh x stavov 2, two shnekovyz of stavov 2, which transmit the movement to the executive body 1 and transport the coal separated from the railway to the drift, two drives 4 of the booster assemblies, which are reported by the rotator noyo and axial movement of the collar, sprockets 5, mounted on both shafts of auger rails 2 and transmitting from them movement to the executive body 1, crown 6, mounted on opposite ends of auger rails 2 and serving for the directional movement of the unit along a removable coal seam, flap 7 - a coal flow separator, connected to the shafts of the widening staves and serving to separate the transported coal flows, the rear shield 8, connected to the flap 7 and serving to eliminate spilling of the transported coal.

The device works as follows.

When the device is operating, the actuators 4, installed on the lower and upper drifts, impart rotational and axial movement to the two screw rollers 2. The screw rollers 2 communicate with the help of sprockets 5 movement to the actuator 1, which, moving along the guiding contour 3, separates coal from the rear plenum along the entire bottom line and delivers battered coal to two augers. During the rotation of the screw stavs 2, the broken coal is transported by them to the drifts.

As the executive body is fed to the face, on one drift the lengthening of the screw rod is made by attaching additional sections, and on the other road gate - shortening of the screw rod, disconnecting the sections that drift.

On the upper and lower drifts are installed augers, screw augers which are equipped with drill bits.

The coal is excavated when the executive body is supplied to the face, alternately in stripes for the uprising and for the fall.

The fastening of the excavated space is made by pneumatic-bolt support following the executive body according to the akhmat scheme.

At the end of the coal strip notch by the fall, i.e., from top to bottom, the executive body of the unit goes to the lower drift and the actuator is moved (rotated) by 180 ° to remove the COAL in the opposite direction, after the uprising, i.e. upwards . The fastening of the excavated space is also made from the bottom up, as the executive body moves.

After the strip has been dredged, after the restoration; 1n and 1p.1, on the upper drift, the organ is moved (rotated); on

80 °, and thereafter the cycle of excavation of the coal is repeated.

This device allows you to significantly increase the intensity of excavation of coal and

labor productivity gfy development of thin coal seams by eliminating the rewiring of work items.
