Description

one

This invention relates to mining equipment.

Excavating and hauling equipment are known, including a combine and a gearbox with a drive sprocket for a scraper price.

A distinctive feature of the proposed installation is that one end of the chain is connected to the drive sprocket, and the other is connected to the rope, which encloses the block on the combine and crimped to the drum, and the gearbox is equipped with two small-toothed gear located on one axle, alternating with two gear wheels rigidly connected with the drive sprocket and drum. This makes it possible to combine the operations of excavation and delivery of rock mass.

FIG. 1 shows the proposed installation; in fig. 2 - drive kinematic diagram; in fig. 3.- diagram of the engagement of a notched gear with a smooth-start sprocket and a gear; in fig. 4 shows a section along A-A in FIG. one.

The final hauling installation consists of a combine 1, a self withdrawing scraper chain 2 with a rope and a winch 3.

The harvester is designed for sinking mines or digging coal and pulling scraping materials with a rope,

The self-extending scraper chain with a rope is designed to transport rock mass.

Skrebkov chain with a rope passes through the blocks 4 installed on the combine. One of the branches, the cable 5, with the free end is wound onto the winch drum, and the other, the chain 6 with the scraper stone 7 of triangular nrizmatic form, passes through the drive and guide sprockets of the winch and the free part is laid on the drift soil.

The winch is designed to drive a scraper with a rope in a reciprocating motion and consists of an electric motor 8, a gearbox 9 of the drum 10, the drive and guide sprockets 11 and 12. The drum and drive sprocket together with the spur gears 13 and 14, having frills 15 and 16, are freely seated on the shaft 17 and are driven into rotation by the semi-gear wheels 18 and 19 sitting on the same axis, on which the protective roller pins 20 and 21 with springs 22 are mounted. On the shaft 17 are freely seated stars 2 3 and 24 with windows 25 where fingers 15 and 16 of wheels 13 and 14 enter.

The stars 23 and 24 are associated with spring 26 and 27 with wheels 13 and 14. The sprockets 23 and 24 with windows 25, the springs 22, 26 and 27 and the protective ones

roller fingers 20 and 21 serve to prevent breakage of the teeth of sprockets 23 and 24 when they accidentally meet with fingers 20 and 21 of semi-gear wheels and to eliminate dynamic impacts when periodically engaged gear of the semi-gear wheels 18 and 19 with wheels 13 and 14.

Couplings 28 and 29 are mounted on shaft 17, which rotate with it, but can move along its longitudinal axis.

The installation works as follows.

When the electric motor of the winch is turned on, through the gears 30-33, the shaft 34 with the knurled wheels 18 and 19 rigidly mounted on it receives a rotary motion.

The semi-gear wheels, in connection with the fact that the gear part is directed in opposite directions, during rotation periodically, every half-turn, alternately interlock with the wheels 13 and 14 and cause them to rotate. The wheel 13 is rigidly connected with the drum, on which the free end of the thrust branch (rope) 5 is fixed, and the wheel 14 with the driving sprocket through which the working branch 6 passes (chain with scrapers). Therefore, during rotation of the iridescent wheels, the drum and the drive sprocket are periodically brought into rotational motion, as a result of which a back and forth movement of the scraper chain with the rope takes place.

Since the drum with the wheel 13 and the drive sprocket with the wheel 14 are freely seated on the shaft 17, and the working 6 and the traction 5 branches are interconnected through the block 4, while rotating one of them is in a free position outside the clutch and rotates in reverse direction.

The case of the encounter between the teeth of the teeth of the notched wheels and the wheels 13 and 14 and the dynamic impacts at the time of their engagement are eliminated by using sprockets 23 and 24 and roller stocks 20 and 21.

The semi-gear wheels, when rotated, first appear in a scene with stars 23 and 24 by means of roller castings, and then with their help with wheels 13 and 14.

If, for example, the roller pin 20, when meeting with an asterisk 23, will not be in its recess, but will meet with the top tooth.

the spring 22 is then compressed, the fore end 20 is retracted, and then it falls between the teeth.

With further rotation of semi-gear

the wheels 18, the spring 26 is extended, and the sprocket 23 smoothly grips the wheel 13, rests against the Yalets 15, after which the teeth of the half-toothed wheel 18 and the wheel 13 enter the clutch accurately and without dynamic

beats.

Pa working branch 6 scrapers secured in such a way that nloskosti acute angle directed to the uprising. When the working branch is not displaced downwards, the scrapers capture the broken mountain mass and transport it downward, and when it is moved upwards, the mass remains in place.

In the process, the combine moves up and there is no working and traction

scraper chain branches with rope,. elongation

their. The elongation is due to that branch

which at this moment is not moving upwards.

Skrebkov chain with rope returns

in the original zeroing rotation leading

sprockets and winch drum at the same time and B in one direction. This is eliminated by securing the drum and the drive sprocket to the hard shaft 17 by means of sleeves 28 and 29.

When the scraper chain with the rope returns to its initial position, the working branch (chain with scrapers), the passage through the drive and guide sprockets of the winch is laid on the drift soil, and the pull branch (rope) is wound on the drum.

Subject invention

Extractive installation, including a combine and a reducer with an irradiation sprocket for a scraper price, characterized in that, in order to ensure the combination of the operations of excavation and delivery of rock mass, one

the end of the chain is connected with a sprocket sprocket, and the other is connected to the rope, which encloses the blocks on the combine and is crimped to the drum.
