Abstract

The invention relates to mining equipment and increases the efficiency of blasting by increasing the impact energy. A hydraulic cylinder (HZ) 2 is connected to the body of the executive body. With the figure head (FG) 3 it is connected to the grippers 4 with elastic arms 5 fixed on the striker 6 located on the ush direction, they are 8. The latter are connected to the blade and have spring 9, stroke limiter 10 and stops 16. On housing 1 for damping impact energy in the absence of rock resistance, pads 12, 13c are located by shock absorbers 14 and 15. When meeting with rock, the feed is stopped and the working fluid is supplied to HZ 2. Rod HZ 2 advances and FG 3 uncovers grapples 4 in the final gender of the striker 6. Then the scraper with FG 3. engulfed by the grips 4 with elastic arms 5, feeds the firing pin 6 to HZ 2. At this, the elastic elements 17 are energized.

Description

f5

The invention relates to the mining industry, namely to the development of minerals.

The aim of the invention is to increase the efficiency of blasting by increasing the impact energy.

FIG. 1 schematically shows the proposed executive body, side view; in fig. 2 is a view A of FIG. 1 (with conditionally removed bottom sheet).

The percussion actuator, Yu, consists of body 1, to which HJapnich is connected to a hydraulic cylinder 2. With a figure head 3, a hydraulic cylinder 2 is connected to grippers 4 with elastic arms 5 fixed to striker 6 by means of lock 7. Striker 6 is freely seated on the shoulder 8, fitted with springs 9 and travel stops 10. Guides 8 are connected to blade 11, and paddles 12, 13 are located on the case with shock absorbers 14, 15 for damping impact energy in the absence of rock resistance. The guides 8 are limited in mobility by the stops 16.

For charging the actuator body, elastic elements 17 are installed in case 1, one end of which interacts with projections 18 of case 1 and the other with striker 6. Openers 19 are mounted on the hydraulic cylinder 2 to open grippers 4 with elastic arms 5 at the end of the stroke. to the mining machine with the help of the bracket 20 and eyelets 21 with a finger 22. The lower part of the body 1 is covered by a sheet 23. To prevent the rock from collapsing, the boards 1 are mounted on the body 1.

The work of the executive body is carried out as follows.

The body of the executive body is attached to the mining machine by means of a bracket 20, eyelets 21 and a finger 22. The body 1 is fed to the rock, and the feed can be carried out on unbroken rock, for example.

The final position of the striker 6. Then, with a reverse stroke, the rod with a figured head 3, gripped by grippers 4 with elastic arms 5, feeds the striker 6 to the hydraulic cylinder 2, while elastic elements 17 are energized. In the final position, the openers 19 open grippers 4 with elastic arms 5 , and they are freed from the figure head 3, and the striker 6 from the action of the charged elastic elements 17 strikes the blade 11 with its mass, which destroys and submerges the rock. If the rock resistance is insignificant and the impact energy of the striker 6 on the blade 11 is not spent on its destruction, then the impact energy is extinguished by shock absorbers 14, 15 installed on the pads 12, 13. In addition, part of the energy of the ulchar is absorbed by springs 9 installed on the guides 8 with travel stops. 10. Guides 8 are limited during stops. 16.

The actuator is again fed forward of the mining machine before the encounter with the intact rock, and the cycle is repeated until the specified volume of rock has been broken.
