Type of making an uproar mining rock drill.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
The utility model provides a kind of environmentally friendly noise reducing type mining rock drill, including rock drill shell, outside the rock drill
Shell surface is provided with vacuum noise reduction cavity, and one end of the rock drill shell is provided with drill rod, and the surrounding of the drill rod is provided with rubber
Glue shock absorbing ring, the ubber shock-absorbing circle is provided with by damping spring and the rock drill cage connection at the top of the drill rod
Plunger, the side of the plunger is provided with lower end chamber, and upper end chamber, the top in the upper end chamber are provided with the top of the lower end chamber
Throttling pore is provided with, it is provided with nitrogen energy-storing device at the top of the throttling pore, the nitrogen energy-storing device is internally provided with
Nitrogen energy-storing device barrier film.
Used as a kind of optimal technical scheme of the present utility model, the surface of the rock drill shell is provided with high pressure oil-feed
Road, the bottom of the high pressure in-line is provided with low pressure oil return line.
Used as a kind of optimal technical scheme of the present utility model, the madial wall of the rock drill shell is provided with sponge sheet.
The beneficial effect that the utility model is reached is：The device is a kind of environmentally friendly noise reducing type mining rock drill, using true
The principle of empty sound insulation, in the additional one layer of vacuum chamber of original shell, most of noise is eliminated, the junction of drill rod and shell
Plus damping device, the good effect for serving damping noise reduction is preferably minimized the harm that user causes when in use,
There is provided a kind of environmentally friendly noise reducing type mining rock drill, existing rock drill is solved because drill rod is constantly touched with shell in vibrations
Hit, the vibrations for causing and noise all bring the problem of very big injury to the body of user.

Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in figure 1, the utility model provides a kind of environmentally friendly noise reducing type mining rock drill, including rock drill shell, it is described
Rock drill case surface is provided with vacuum noise reduction cavity, and one end of the rock drill shell is provided with drill rod, the surrounding of the drill rod
Ubber shock-absorbing circle is provided with, the ubber shock-absorbing circle passes through damping spring and the rock drill cage connection, the top of the drill rod
Portion is provided with plunger, and the side of the plunger is provided with lower end chamber, upper end chamber, the upper end are provided with the top of the lower end chamber
Throttling pore is provided with the top of chamber, nitrogen energy-storing device is provided with the top of the throttling pore, the nitrogen energy-storing device it is interior
Portion is provided with nitrogen energy-storing device barrier film.
The surface of rock drill shell is provided with high pressure in-line, and the bottom of the high pressure in-line is provided with low pressure oil return
Road, is easy to the turnover of oil sources.
The madial wall of rock drill shell is provided with sponge sheet, strengthens soundproof effect.
The device is a kind of environmentally friendly noise reducing type mining rock drill, when needing with the device, by high pressure in-line 11
Hydraulic oil enters the lower end chamber 7 of plunger 6, promotes plunger 6 to run up, and plunger 6 pushes up valve pocket 10 in uphill process
It is dynamic, until fixed position, then hydraulic oil by between valve pocket 10 and plunger 6 by the oil inlet demarcated to upper end chamber
8 fuel feeding, at the same nitrogen energy-storing device barrier film 13 also upward compressed nitrogen carries out energy storage.When the fluid pressure that the upper surface of plunger 6 is subject to
More than lower end fluid pressure when, the imbalance of power makes plunger 6 accelerate to move downward, while nitrogen energy-storing device 14 provides quick fortune
Move required oil mass.During moving downward, plunger 6 opens throttling pore 9, valve pocket 10 is also declined.Plunger 6 continues
Move downward, until being collided untill producing strike with drill rod 3.Valve pocket 10 has been cut off to upper end chamber 8 during moving downward
Fuel feeding, and it is communicated with low pressure oil return line 12, such whole process is returned to initial position.So go round and begin again, making can
Automatically continuously hit.During strike, ubber shock-absorbing circle 4 and damping spring 5 can significantly cut down drill rod 3 and rock drill
Vibration and noise that the collision of shell 1 is produced, the noise of interior arrangement can also be weakened most after by vacuum noise reduction cavity 2.
The beneficial effect that the utility model is reached is：The device is a kind of environmentally friendly noise reducing type mining rock drill, using true
The principle of empty sound insulation, in the additional one layer of vacuum chamber of original shell, most of noise is eliminated, the junction of drill rod and shell
Plus damping device, the good effect for serving damping noise reduction is preferably minimized the harm that user causes when in use,
There is provided a kind of environmentally friendly noise reducing type mining rock drill, existing rock drill is solved because drill rod is constantly touched with shell in vibrations
Hit, the vibrations for causing and noise all bring the problem of very big injury to the body of user.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to the utility model with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent.It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc.,
Should be included within protection domain of the present utility model.
