Abstract

Use: mining operations. Invention: a bunker-loader included in the tunnel complex is equipped with two shares. The rear part of the plowshares is fixed under the bottom of the bunker-reloader. And the front is connected to the frame of the hopper by means of hydraulic cylinders. The self-propelled carriage is equipped with a hopper, which is made in the form of a hollow box with an opening bottom and mounted under the frame of the bottom of the self-propelled car. 3 sludge.

Description

The invention relates to equipment for mine workings, namely, tunneling complexes that protect the soil of the mine when it penetrates.

Known miner combine, the chassis of which is equipped with a blade placed in front of the Caterpillars under the executive body.

However, the used blade of the combine is complicated in design, it works cyclically only when the executive body is raised, and its use on a tunneling machine with a rotor or planetary executive body is impossible.

Closest to the invention is a tunnel-mining complex consisting of a combine, a bunker reloader and a self-propelled car. At the same time, the cleaning of the soil of the mine workings is carried out, if necessary, for example by bulldozers with loaders and

delivery cars or self-propelled cars.

The main disadvantage of this production-mining complex is low productivity due to the extra time spent on stripping the rock mass of the mountain mass and the use of loading machines and bulldozers.

The aim of the invention is to increase the productivity of the complex and reduce the loss of the mineral due to a more complete clearing of spills, carried out simultaneously with the tunneling works.

The goal is achieved by the fact that. in the tunnel complex, which includes a combine, a bunker-loader and a self-propelled car, the bunker-loader is equipped with two plowshares, the rear part of which is pivotally fixed under its bottom, and the front part is connected to the loader frame

by means of hydraulic cylinders, while the self-propelled carriage is equipped with a storage bin, made in the form of a hollow box with an opening bottom and mounted under the frame of the bottom of the self-propelled carriage.

FIG. 1-3 shows the proposed tunnel complex (in Fig. 1 - a bunker-loader with mounted plowshares with reflecting plates; in Fig. 2 - a self-propelled car at the moment of unloading of the rock mass from the body and spilling from the bunker-loader onto the conveyor-loader) ,

The plowshares 1 with reflecting plates are mounted on the bunker-reloader, the rear part being connected to the frame of the bottom of the bunker reloaders by means of hydraulic cylinders 3 with shock-absorbing springs. Plowshares are located at an angle of about 30-4517 to the wall of the mine. The storage bin 6 is mounted on the bottom of the unloading console of the self-propelled car. A pair of hydraulic cylinders 4 serves to open the loading bottom 7 of the storage bin 6 when loading the rock mass into its cavity, and a pair of hydraulic jacks 5 serves to open the bottom 8 when unloading the rock mass (see Fig. 3) to the scraper loader 9.

The tunnel complex operates as follows.

During the movement of the bunker-reboiler behind the tunneling machine, the spillage of the rock mass on the excavation soil is collected into the roll 2 in its center with the help of plowshares with reflective shields mounted on the bunker-reloader at an angle to the walls of the excavation. Plowshares 1 are made with hydraulic cylinders 3, with the help of which they are raised or lowered if necessary, for example, when moving the complex to the next mine workings. When the self-propelled car moves, the boot bottom 7 of the accumulator 6 is pressed against the soil of the mine workings by means of hydraulic cylinders 4, and the accumulator 6 is loaded in this position. After filling the body of the self-propelled car, the boot bottom 7 of the accumulator 6 lifts up

drive 6, transfer it to the transport position, then the self-propelled car moves through the mine workings to the place of unloading onto the scraper loader

9, where the mining mass is unloaded from the body of the self-propelled car, while the hydraulic cylinders 5 are simultaneously opened by the discharge bottom 8 of the accumulator 6 and the mass transport spillage is unloaded into the scraper loader 9.

After the end of the unloading by a pair of hydraulic cylinders 5, the discharge bottom 8 rises up, transferring the storage b to

the transport position and the self-propelled carriage return to the tunneling machine, after which the cycle is repeated.

The dimensions of the accumulator are determined in Dependence on the load-carrying capacity of the self-propelled car. For example, for the conditions of the mines of the Belarusian Byelorussian complex of the self-propelled wagon 5BC-15, these dimensions are: length 0.63 m, width 1.8 m, height 0.2 m, i.e. the capacity is 0.0227 mu, which ensures simultaneous delivery of the rock mass from the combine and stripping of spillage to the conveyor-loader.

The use of a tunneling complex increases the efficiency of mine workings by increasing the load on the face and ultimately reduces the cost of production.
