Description
Technical field
The present invention relates to a kind of pneumatic tools, more particularly to a kind of low-noise environment protection Pneumatic chain saw.
Background technique
Pneumatic saw blade is mainly used for timber, nonmetal pipeline, coal cinder, concrete and masonry etc. using compressed air as power
The cutting of material cracks, and is also applied for the slotting class operation to soft rock mass and wall.Existing pneumatic saw blade is in the course of work
In, air pump work generates strong noise and dust, and the method for eliminating noise is mostly that the stomata that begins to rehearse on motor shell adds one again
Hood exhaust, makes noise quickly shed, but after testing in this way, and the noise of gas vent is up to 80~90 decibels when operation, to body
Body has certain harm, and the dust that exhaust outlet evokes is easy hood to block.Although furthermore the coolant system among carrier bar is straight
Flushing saw blade is connect, cooling effect is played, there is local depositing dust function, also only for the position of saw blade cutting, and can not be applied to
Given this dust, the fine particle evoked around saw blade is more in the artificial large area spray in work corner, but money of wasting water
Source works asynchronous, and dust-laying effect is limited, cannot effectively eliminate spark, brings certain risk to safety in production.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of low-noise environment protection Pneumatic chain saws.
The present invention is achieved by the following technical solutions: a kind of low-noise environment protection Pneumatic chain saw, including saw blade, machine

Specific embodiment
A kind of present invention low-noise environment protection Pneumatic chain saw work is further retouched with specific embodiment with reference to the accompanying drawing
It states:
Fig. 1 is a kind of structural schematic diagram of low-noise environment protection Pneumatic chain saw of the present invention, and Fig. 2 is the enlarged drawing of F in Fig. 1,
Fig. 3 is the top view of Fig. 1.In figure, which cuts off the water supply including saw blade 1, casing 18, set on the Pneumatic-hydraulic interlocked of engine body exterior
Protector 12, the water outlet 13 on Pneumatic-hydraulic interlocked no water protector 9, the exhaust outlet 3 of air motor 2 and air motor 2,
Disk seat 4 is arranged in the exhaust outlet 3 of air motor 2, and phonocatheter 6 is arranged on disk seat 4, is provided in phonocatheter 6 and air motor
The main sound channel 7 that exhaust outlet 3 communicates, the outside of phonocatheter 6 are cased with the closed echo casing 8 in front end, and 8 end of echo casing is solid
Due to forming echo road 9 between disk seat 4, echo casing 8 and phonocatheter 6, echo casing 8 is set on the tube body at 4 position of disk seat
It is equipped with aperture 5, the outside of echo casing 8 is cased with the open secondary echo casing 10 in front end, and secondary 10 end of echo casing is fixed
Secondary returning sound channel 11 is formed between disk seat 4, echo casing 8 and secondary echo casing 10, the end of secondary echo casing 10 is set
It sets with foraminate dust cover 20.Spray tube 17 is arranged in 1 side of saw blade, and spray tube 17 passes through the water filling seat 15 on casing 18
It is fixed on casing 18,19 face saw blade 1 of fog-spray nozzle is arranged in 17 front end of spray tube, and spray tube 17 is close to the setting of water filling 15 one end of seat
There is outlet water control valve 16, the other end is fixedly connected into water sebific duct 14, and sebific duct 14 of intaking connects Pneumatic-hydraulic interlocked no water protector 12
Water outlet 13.
This pneumatic saw blade is in use, first open outlet valve 16, and pressure water is from Pneumatic-hydraulic interlocked no water protector 12
Water inlet 21 enters Pneumatic-hydraulic interlocked no water protector 12, and Pneumatic-hydraulic interlocked no water protector 12 is a kind of when external hydraulic pressure reaches one
When determining intensity, it could be connected and export pressure water and compressed air from water outlet 13 and gas outlet 23, as the Pneumatic-hydraulic interlocked guarantor that cuts off the water supply
When pressure water in shield device 12 reaches certain pressure, pressure water is flowed out from water outlet 13 enters water inlet sebific duct 14, by filling the water seat
Spray tube 17 on 15 is sprayed at 1 position of saw blade.When the water pressure of Pneumatic-hydraulic interlocked no water protector 12 reaches certain pressure, gas
The air inlet 22 and 23 connection of gas outlet of water linkage no water protector 12, compressed air are led to from gas outlet 23 by air inlet pipe 24 defeated
Air motor 2 is sent to provide operation power, air motor 2 starts turning, noise by air motor 2 exhaust outlet 3 into
In the cavity for entering main sound channel 7, after noise encounters the front end closing reflection of echo casing 8, enter into echo road 9, then through aperture 5
Secondary echo casing 10, sheds from secondary returning sound channel 11, and noise is sufficiently decayed, to reduce noise.Start at this time saw blade 1 into
Row cutting operation, saw blade 1 cut and generate dust around material, will appear high temperature with saw blade 1 in cutting process, sebific duct 14 of intaking
Water constantly from spray tube 17 act on saw blade 1 and its surrounding.Enough water mist sprinklings on saw blade, are realized saw blade by fog-spray nozzle 19
The effect of cooling effectively prevent the generation of spark, while forming cascade around saw blade work, by the dust of generation, subtle
Grain isolation reaches depositing dust effect.Once cutting off the water, the gas outlet 23 on Pneumatic-hydraulic interlocked no water protector 12 stops supplying gas, pneumatic horse
It stops working immediately up to 2, but saw blade 1, still in high temperature, Pneumatic-hydraulic interlocked no water protector 12 is shutting down work and movement rank of cutting off the water
It is connected to the time difference, the hydraulic pressure of surplus also has certain pressure, and pressure water is constantly delayed from water outlet 13 and is discharged, and fog-spray nozzle 19 is still
It acts directly on and continues spray cooling on saw blade 1, efficiently solving pneumatic tool in industries such as mine, petrochemical industry has requirement of explosion proof
The safe handling problem in place, eliminates security risk present in pneumatic tool use.
Product of the present invention can effectively eliminate dust in operation process, maintain Environmental Health, while existing in mine down-hole
In use, eliminating the high temperature being likely to occur, pyrophoric behavio(u)r in explosive hazard environment, it is ensured that safety in production.Product of the present invention structure
It is compact, simplify the quantity of technological equipment, versatility is good, and replaces cooling emulsion more environmentally-friendly.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
