Description
Technical field
This utility model relates to a kind of water flushing mechanism, particularly relates to a kind of water flushing being applicable to air drill
Structure, relates to a kind of air drill with this water flushing mechanism simultaneously.
Background technology
In rock drill work process, current will be supplied to liquid drugs injection, by drill steel, arrive at the bottom of hole.A part of current are used for
Rock dust at the bottom of moistening and flushing hole reaches the purpose of depositing dust, ideally, when rock drill works, and the hydraulic pressure of supply liquid drugs injection
Blast should be less than, if the hydraulic pressure in liquid drugs injection will have entrance air channel and the risk of cylinder body higher than blast, current, destroys moving component
Oil film, thus affect the normal work of rock drill.Finally, main parts size in rock drill is made to be corroded or grind wound.
Due to the change of rock drill work physical features, hydraulic pressure changes the most therewith, it is impossible to ensure that hydraulic pressure is always less than blast, routine
The water flushing mechanism of air drill is not before with this utility model, and when the hydraulic pressure in liquid drugs injection is less than blast, hydraulic pressure is not
Can always adjust；Water valve on current market, the change in pressure of the hydraulic pressure dependence feed pipe in liquid drugs injection, therefore,
When the hydraulic pressure in liquid drugs injection is higher than blast, water can pour in down a chimney to body；The water flushing mechanism of existing air drill can be one
Hydraulic pressure in regulation liquid drugs injection in fixed scope, but it cannot be guaranteed that when hydraulic pressure is higher than blast, can regulate to blast.
Summary of the invention
Technical problem
The technical problems to be solved in the utility model there is provided a kind of water flushing mechanism for rock drill work, can control
Hydraulic pressure in controlling the water circulation pin, and water pressure energy changes along with the change of wind pressure of work；And rock drill water flushing mechanism
In provide an easy device, in rock drill work process, it is possible to the hydraulic pressure in regulation liquid drugs injection is less than blast.
Further, this utility model provides the air drill comprising this water flushing mechanism, and the punching of this water
Washing machine structure can ensure that the hydraulic pressure regulation in liquid drugs injection is to working less than under blast.
Technical scheme
In order to solve above-mentioned technical problem, this utility model to realize above-mentioned target, it is desirable to provide can control liquid drugs injection
The water flushing mechanism of the air drill of middle hydraulic pressure, including a water valve body；One can move to the position fixed, and then control
Current in controlling the water circulation pin open and close the water valve of function.
Water valve body comprises a passage, under default air pressure, it is possible to make valve open, and current can be made to pass through；
And together with valve, it is possible to prevent the hydraulic pressure in liquid drugs injection from exceeding default blast, in the case of there is no hydrodynamic resistance, water valve valve
Can freely open.
Water valve comprises a passage so that the hydraulic pressure in liquid drugs injection enters the other end of valve, if the hydraulic pressure in liquid drugs injection exceedes
During the pressure preset so that valve moves to the direction cut out, control to enter the discharge of liquid drugs injection, hydraulic pressure size in regulation liquid drugs injection.
It is placed on the water valve other end and places a spring, it is possible to promote water valve to move, because water valve comprises one to the direction closed
Passage makes the water in liquid drugs injection enter the other end of water valve so that hydraulic pressure is before exceeding blast, and water valve cuts out, and prevents hydraulic pressure from surpassing
Cross preset pressure.And when rock drill quits work, spring can promote water valve to closed mode, stops supplying water.
This utility model relates to a kind of water flushing mechanism, includes the air drill with this water flushing mechanism simultaneously.
Beneficial effect
Air drill of the present utility model and flushing machine thereof are owing to being provided with this structure so that the most external water source pressure
Power is how many, can ensure in rock drill work process, and the hydraulic pressure in liquid drugs injection is less than blast, prevents water from pouring in down a chimney to body, destroys
The oil film of parts, causes parts corrosion or grinds wound.

Detailed description of the invention
Utility model relates to a kind of controlling the water flushing mechanism of hydraulic pressure in rock drill liquid drugs injection, a kind of rock drill such as Fig. 1 institute
Showing, this rock drill contains cylinder body portion 2, shank body 3.Cylinder body portion 2 defines piston 5 reciprocable in cylinder body 4, and rushes
Hit drill steel.Traditional rock drill is generally used for down-hole and engineer operation, and its rock drill is equipped with liquid drugs injection 6, the water punching of air drill
Washing machine structure is often referred to 11, and is arranged in the shank body 3 of rock drill 1, the flow of water in controlling liquid drugs injection 6.
The water flushing mechanism 11 of air drill of the present utility model comprises a water valve body 9, and is tightened in shank body 3
On.Water valve body 9 provides water valve body duct 14, water valve duct 24, water valve body air inlet port 23 and water valve body water inlet 21, such as Fig. 2
Shown in；The water valve small end 13 of water valve 29 is arranged at water valve body duct 14, and can realize moving back and forth, the 2nd O RunddichtringO
12, the 3rd O RunddichtringO 15 is arranged on the appropriate location of water valve 29.The water of liquid drugs injection pad 19 is inserted in the liquid drugs injection end 17 of liquid drugs injection 6
In pincushion groove 34, liquid drugs injection pad 19 inserts at the water valve body opening 30 of water valve body 9, is then fixed by the gentle pincushion of air tube 32 18.Water
Valve body 9 is installed and is screwed in the duct of shank body 3 so that liquid drugs injection pad 19, air tube pad 18 and copper packing 33 are in impaction state.Water valve
