Abstract
The utility model relates to a spraying device on an entry-driving machine, in particular to an inner spraying nozzle which is arranged on the head of an entry-driving machine to realize water spray, cool down and arc extinction in the course of coal mine driving. A core, a sliding bush and a locating disk are arranged in the shell of the nozzle. One end of the core is provided with a jet hole and an opening on the other end is in sliding fit with one end of the sliding bush. A water guide heart with a spiral line is arranged in the inner cavity of the heart, and the other end of the sliding bush is in sliding fit with the locating disk. The outermost lateral wall is provided with a flange which is in sliding fit with the shell. On one side of the flange, the sliding bush forms an enclosed cavity with the shell and the core. The enclosed cavity is communicated with an inlet opening through the side opening of the sliding bush. On the other side of the flange, the sliding bush forms a spring cavity with the shell and the locating disk. A spring is arranged in the spring cavity, and a pricker which is corresponding to the jet hole is arranged on the centre hole of the sliding bush. The utility model overcomes the abuse that departed nozzle is difficult to be dredged, when the nozzle is clogged. So the automatic dredging can be realized conveniently and the safety of the dust removal effect and the mining working can be improved.
Description
Technical field
The utility model relates to the sprayer unit on the development machine, specifically is in the coal mine roadway tunneling process, is installed in the internal spraying nozzle that the development machine head is realized atomizing de-dusting, cooling, arc extinguishing.
Background technology
At present, generally have spray nozzle on development machine, its function is the rotation along with cutterhead in the headwork process, and when realizing the coal petrography cut, ejection water smoke is realized depositing dust, cooling, arc extinguishing function to cut tooth and coal petrography contact site.Its structure mainly is to be processed with the venturi helix in nozzle inner walls to make the water rotation with vaporific ejection.But because the working environment harshness, solid particle is more, and often with the rib extruding, collide the frequent blockage phenomenon of nozzle ejiction opening, and cisco unity malfunction influences dedusting, even the danger of sparking is arranged.
The utility model content
In order to solve the problem of spray nozzle clogging, the utility model provides a kind of internal spraying nozzle, and this nozzle not only spray effect is good, and the nozzle that has stopped up is realized from mediation.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of internal spraying nozzle, has housing, cored body in the described housing, sliding sleeve, positioning disk, core body one end has hole for water spraying, other end opening and sliding sleeve one end are and are slidingly matched, the core body inner chamber is equipped with the water guide core of band helix, the sliding sleeve other end and positioning disk are and are slidingly matched, and sliding sleeve outermost sidewall is provided with housing and is the flange that is slidingly matched, in flange one side, form enclosed cavity between sliding sleeve and housing and the core body, enclosed cavity communicates with the inlet opening by the side opening of sliding sleeve, at the flange opposite side, forms spring cavity between sliding sleeve and housing and the positioning disk, spring is housed in the spring cavity, and the sliding sleeve centre bore is equipped with and the corresponding cleansing pin of hole for water spraying.
Described water guide core side is fixed by jackscrew.
Described positioning disk and housing are by being threaded.
Described cleansing pin is welded in the central hole of sliding sleeve.
The sidepiece of described spring cavity has passage, is provided with porous ceramic bodies at nose end.
The beneficial effects of the utility model are:
The utility model changes the way of conventional spout at enclosure interior processing venturi helix, and adopts the water guide core that has helix to replace, and its difficulty of processing the more important thing is that much smaller than the former inside is provided with a cleansing pin.When the nozzle operate as normal, cleansing pin is in retracted position, realizes spraying; When foreign matter enters nozzle it is stopped up, only need external water source is closed, open again, can make the nozzle that has stopped up recover operate as normal, thereby overcome the big drawback of spray nozzle clogging mediation difficulty in the past, realize mediation automatically easily, and then the security that improves dust removing effects and mining work.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Among the figure, 1 is housing; 2 is core body; 3 is hole for water spraying; 4 is the water guide core; 5 is spring; 6 is positioning disk; 7 is sliding sleeve; 8 is the inlet opening; 9 is centre bore; 10 is cleansing pin; 11 is flange; 12 is ceramic body; 13 is side opening; 14 is enclosed cavity; 15 is jackscrew.
The specific embodiment
Below in conjunction with accompanying drawing and example the utility model is further specified.
As shown in Figure 1, a kind of internal spraying nozzle, cored body 2 in the housing 1 of this nozzle, sliding sleeve 7, positioning disk 6, core body 2 one ends have hole for water spraying 3, other end opening and sliding sleeve 7 one ends are and are slidingly matched, core body 2 inner chambers are equipped with the water guide core 4 of band helix, water guide core 4 sides are fixing by jackscrew 15, sliding sleeve 7 other ends and positioning disk 6 are and are slidingly matched, sliding sleeve 7 outermost sidewalls are provided with housing 1 and are the flange 11 that is slidingly matched, and in flange 11 1 sides, form enclosed cavity 14 between sliding sleeve 7 and housing 1 and the core body 2, enclosed cavity 14 communicates with inlet opening 8 by the side opening 13 of sliding sleeve 7, at flange 11 opposite sides, form spring cavity between sliding sleeve 7 and housing 1 and the positioning disk 6, spring 5 is housed in the spring cavity, sliding sleeve centre bore 9 is welded with and hole for water spraying 3 corresponding cleansing pins 10, and positioning disk 6 and housing 1 are by being threaded.
The course of work of the present utility model is as follows:
Housing 1 links (direction of arrow is the water inlet direction as shown in Figure 1) with external water source, when press water enters thus, through sliding sleeve 7 bottoms, by sliding sleeve inlet opening 8, water guide core 4, by hole for water spraying 3 with vaporific ejection.When hole for water spraying 3 enters foreign matter generation obstruction, close the water source, enclosed cavity 14 pressure reduce, and sliding sleeve 7 drives cleansing pin 10 and releases under spring 5 thrust, eject foreign matter, realizes dredging.When opening the water source, press water enters through the inlet opening 8 of sliding sleeve 7, because this moment, cleansing pin 10 blocked hole for water spraying 3, press water will be entered the enclosed cavity 14 on spring 5 tops by the side opening 13 of sliding sleeve 7, under the pressure effect of press water, promotion sliding sleeve 7, cleansing pin 10 move down, with spring 5 compressions, thereby open hole for water spraying 3, rearming.
For preventing spring cavity generation vacuum, have passage at its sidepiece, stop up for preventing passage, be provided with porous ceramic bodies 12 at nose end.
