Abstract
The invention relates to an internal spraying device for a tunneling machine. A tooth holder is mounted on the surface of a cutting head body of a cavity according to the direction of a helical line, cutting teeth are mounted on the tooth holder, and the connecting part of the back end of the tooth holder and the cutting head body is provided with a through hole which communicates with a nozzle arranged on the tooth holder. The internal spraying device has the advantages of simple structure, reasonable design, difficult blockage, relatively short fog distance and good spraying effect; the nozzle is inclined backwards, and a water path arrives at the nozzle through the tooth holder.
Description
Technical field
The invention belongs to a kind of inner sprayer unit, especially relate to a kind of colliery internal spraying device for development machine.
Background technology
At present, China's development machine internal spraying ground structure mostly is spraying split type, front, and spraying point location is more difficult, spraying distance, nozzle welding are forbidden, made dust deposit, easily blocks.
Summary of the invention
It is an object of the invention to overcome the weak point existed in above-mentioned technology, it is provided that a kind of simple in construction, reasonable in design, nozzle tilts backwards, the internal spraying device for development machine that spray effect is good.
In order to achieve the above object, the technical solution used in the present invention is: be provided with toothholder by hand of helix on the body of the cutting head surface of cavity, pick setting on it, position, toothholder rear end and the body of the cutting head junction have a through hole and connect with the nozzle of setting on toothholder.
The invention have the advantage that
Simple in construction, reasonable in design, nozzle tilt backwards, not easily stifled match, and mist distance is shorter, and water route reaches nozzle by toothholder, and spray effect is good.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present invention；
Fig. 2 is Figure 1A-A sectional view；
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
By Fig. 1-Fig. 2 it can be seen that the present invention is provided with toothholder 2 by hand of helix on the body of the cutting head 4 surface of cavity, pick setting 1 on it, position, toothholder 2 rear end and the body of the cutting head 4 junction have a through hole 6 and connect with the nozzle 3 of setting on toothholder 2.
Described nozzle 3 axis and after to cut the top tangent plane distance of tooth 5 be 1mm-15mm.
Development machine internal spraying cutterhead pick mostly is helical row and is staggered, and for helical row, this invents adjacent two teeth on same helix, distance certain outside the crown of a tooth after the nozzle spray on denticle above.
Toothholder 2 of the present invention is welded on the body of the cutting head 4 surface, pick 1 is arranged on toothholder 2, nozzle 3 is arranged on toothholder 2, and in the body of the cutting head 4, corresponding each toothholder 2 has water hole, has limbers in toothholder 2 equally, communicate with the water hole in the body of the cutting head 4, communicating with nozzle 3, water under high pressure, by the A point of the body of the cutting head 4, enters in nozzle 3 through toothholder 2 simultaneously, being sprayed to next pick 1 by nozzle 3 to spray from crown X point, X numerical value is between 1mm-10mm.
Claims (2)
1. an internal spraying device for development machine, including the body of the cutting head, it is characterized in that: on the body of the cutting head (4) surface of cavity, by hand of helix, toothholder (2) is installed, pick setting (1) on it, toothholder (2) position, rear end and the body of the cutting head (4) junction have a through hole (6) and connect with the upper nozzle (3) arranged of toothholder (2).
2. internal spraying device for development machine according to claim 1, it is characterised in that: described nozzle (3) axis and after to cut the top tangent plane distance of tooth (5) be 1mm-15mm.
