Description
Technical field
The utility model relates to a kind of humidifier, particularly relates to a kind of horizontal shaft type development machine internal spraying mechanism.
Background technology
Up to the present mine mainly contains two classes with development machine: longitudinal axis formula and horizontal shaft type.The inside and outside spraying system of longitudinal axis formula is substantially perfect, does not carry out internal spraying, but substantially can meet dedusting and cooling needs but still realize low-cost all toothholders.And horizontal shaft type only have external spraying, internal spraying is a blank always, and especially all toothholders are for internal spraying.Distant due to the positional distance cutting drum of external spraying, so dust removing effects is undesirable.In running order pick is all wrapped in the middle of material substantially in the course of the work, and the water that external spraying comes can not see through the timely cooling pick of material, makes pick when cutting harder material, easily produce spark, and especially high gas environment is greatly dangerous.Due to not in time cooling, higher temperature all reduces the abrasion resistance of pick and intensity, causes the life-span of pick to subtract greatly.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of horizontal shaft type development machine internal spraying mechanism, and it improves dust removing effects, has reached timely dedusting, cooling, antispark function.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of horizontal shaft type development machine internal spraying mechanism, it is characterized in that, it comprises water pipe, reducer shell, sealing shroud, output shaft, cutting drum, toothholder, nozzle, sealing shroud is provided with a sealing shroud water hole, output shaft is provided with an output shaft pipeline, cutting drum is provided with a cutting drum cavity and a cutting drum pipeline, a part for water pipe is positioned at reducer shell, another part of water pipe is communicated with sealing shroud water hole through after reducer shell, one end of output shaft pipeline and water seal form an annular seal space, annular seal space is communicated with sealing shroud water hole, the other end of output shaft pipeline is communicated with cutting drum cavity, one end of cutting drum pipeline is communicated with cutting drum cavity, the other end of cutting drum pipeline and nozzle, toothholder is communicated with, a pick is fixed on the external surface of cutting drum by toothholder, nozzle is fixed on toothholder and towards pick.
Preferably, between described two water pipes, be provided with an idle pulley, idle pulley is connected with an output gear.
Preferably, the junction in described water pipe and sealing shroud water hole is provided with first sealing ring, is provided with second sealing ring between sealing shroud and output shaft.
Preferably, described output shaft pipeline be shaped as I-shaped.
Preferably, the material of described water pipe is stainless steel material.
Preferably, described toothholder is provided with a screwed hole, and nozzle is fixed on toothholder by screwed hole.
Positive progressive effect of the present utility model is: the utility model improves dust removing effects, has reached timely dedusting, cooling, antispark function, realizes toothholder for internal spraying.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model horizontal shaft type development machine internal spraying mechanism.
Fig. 2 is the structural representation of the element such as cutting drum and nozzle in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As depicted in figs. 1 and 2, the utility model horizontal shaft type development machine internal spraying mechanism comprises water pipe 1, reducer shell 2, sealing shroud 3, output shaft 4, cutting drum 5, toothholder 6, nozzle 8, sealing shroud 3 is provided with a sealing shroud water hole 14, output shaft 4 is provided with an output shaft pipeline 15, cutting drum 5 is provided with a cutting drum cavity 17 and a cutting drum pipeline 18, a part for water pipe 1 is positioned at reducer shell 2, another part of water pipe 1 is communicated with sealing shroud water hole 14 through reducer shell 2 is rear, one end of output shaft pipeline 15 and water seal 12 form an annular seal space 16, annular seal space 16 is communicated with sealing shroud water hole 14, the other end of output shaft pipeline 15 is communicated with cutting drum cavity 17, one end of cutting drum pipeline 18 is communicated with cutting drum cavity 17, the other end of cutting drum pipeline 18 and nozzle 8, toothholder 6 is communicated with, a pick 7 is fixed on the external surface of cutting drum 5 by toothholder 6, nozzle 8 is fixed on toothholder 6 and towards pick 7.Being shaped as of output shaft pipeline 15 is I-shaped, facilitates like this water flowing and can not produce obstruction.Toothholder 6 is provided with a screwed hole 61, and nozzle 8 is fixed on toothholder 6 by screwed hole 61.
Between two water pipes 1, be provided with an idle pulley 9, idle pulley 9 is connected with an output gear 10, and idle pulley 9 is for changing rotation direction, and output gear, for transmission, facilitates to reducing gear.
Water pipe 1 is provided with first sealing ring 11 with the junction in sealing shroud water hole 14, is provided with second sealing ring 13 between sealing shroud 3 and output shaft 4, and anti-like this sealing leaks.The first sealing ring 11 and the second sealing ring 13 all adopt O RunddichtringO, improve like this sealing performance.The material of water pipe is stainless steel material (concrete model can be 1Cr18Ni9), improves like this intensity, reduces costs.
Operating principle of the present utility model is as follows: secondary water enters through water pipe, in reducer shell, being divided into two-way (two line structures are in full accord) enters in sealing shroud, then by annular seal space, enter in output shaft, by output shaft pipeline, enter again in the cutting drum cavity of cutting drum, after the cutting drum pipeline on cutting drum, by nozzle, spray again, the angle of current ejecting is just in time aimed at the alloy part of pick, current have finally reached timely dedusting after the atomization of nozzle, cooling, antispark function, improve dust removing effects, realize toothholder for internal spraying.In sum, water pipe is communicated with sealing shroud through after reducer shell, sealing shroud is communicated with (this mode of communicating can be rotatory sealing mode of communicating) by the second sealing ring with output shaft, output shaft is communicated with cutting drum cavity, and cutting drum pipeline is communicated with nozzle, toothholder.For preventing corrosion, the surface of sealing shroud adopts the antirust processing of chromium plating.Sealing shroud belongs to dynamic connection with being connected of output shaft, therefore in the junction in water pipe and sealing shroud water hole, adopts the leakage of the anti-sealing of mode of the first sealing ring.For preventing that the water of cutting drum cavity from leaking, and is provided with the second sealing ring between output shaft and cutting drum.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
