SU1446293A1 - Arrangement for supplying sprinkling fluid to mine machine cutter - Google Patents

Abstract

The invention relates to mining equipment, in particular to mining and mining machines. The goal is to increase the reliability of work. mechanism for regulating the supply of irrigating fluid to the cutter. The device for supplying fluid to the cutter includes a tool holder with a hole in which the cutter 4 is installed. The latter is placed with the possibility of longitudinal movement. The tool post is made of two mating cylinders.

chambers of different diameters of the chamber (K) 6 with the spool 7. Most of the cavities are made with the possibility of intersection with the hole for installing the cutter 4. Spool 7 is made of the corresponding K 6 conjugated cylinders of the PoB, the tail part of the spool 7 is located in a guaranteed gap between its end face and the base K 6. The smaller diameter of the cylinder ends with a head with a tapered surface 13 and a needle 14; The diameter of the needle 14 is equal to or slightly smaller than di 6293

meter nozzle 9. In K 6, water from the water K crown enters channel 11 in the crown body and channel 12 in the tool holder and channels 15, 16 to the nozzle 9. When the tool leaves the cutting zone, the spool 7 returns to its original position by pressure water in the system due to the difference of the end surfaces of the spool inlet and outlet. The channels 16 overlap and the head 14 will enter the nozzle, clean it and protect it from a possible blockage. 3 il.

The invention relates to mining equipment, in particular to mining and mining machines, the executive bodies of which are equipped with cutters and have systems for supplying irrigating fluid to the cutters in order to suppress dust and create conditions that prevent the explosion of methane and coal dust from freaking spark arising during destruction rock cutters.

The purpose of the invention is to increase the function of the mechanism for regulating the supply of irrigating fluid to the cutting unit.

FIG. 1 shows the device in the initial position; in fig. 2 - the same in the working position; in fig. 3 - section on. FIG. 2

The device consists of the crown 1 with the tool holders 2. In the longitudinal hole 3 in the slot. in which a special spool 7 is located. The step chamber the front ends in a flat or concave conical surface 8 and the nozzle 9, and the samples are sealed behind the back 10. In this chamber, water from the water chamber of the crown enters through channel 11, which has

with in the crown case, and channel 12 in the tool holder,

The spool 7 has the shape of eccentrically connected cylinders of different diameters, with the smaller cylinder ending with a head with a tapered surface 13 and a needle 14, and the diameter of the needle is equal to or slightly less than the diameter of the nozzle 9.

In the spool for the passage of water to the nozzle there are a main channel 15 and output channels 16;

The movement of the spool is produced by the cutter, which under the influence of the cutting force moves in the socket until the bearing surface 17 of the tool is abutted against the bearing surface 18 of the tool holder. In this case, the bearing surface of the tool holder 19 will act on the slot 20, having a spool, and will ensure its movement. In this case, the needle 14 will come out of the nozzle 9 and open the exit channels 16. The water will enter the nozzle and to the cutter. .How. only the cutter leaves the re- | 3ani zone, the spool is in its original position by the pressure of the WATER in the system due to the difference in the end surfaces of the spool at the inlet and outlet. At the same time, the channels 16 will overlap and the needle 14 will enter the nozzle, clean it and protect it from possible35

go clogged. Formula
