Description
Technical field
The present invention relates to a kind of row's powder water functions of physical supply technical fields of hydraulic drill, relate in particular to a kind of mine
The new hydraulic drill row's powder water feed mechanism used in exploitation, highway, railway, water conservancy, tunnel construction engineering.
Background technology
The operation principle of hydraulic drill is：Hydraulic drill is using high pressure water as power, by matching somebody with somebody flow control valve control
Reciprocating motion of the pistons, during stroke, piston impact drill steel and bore bit chisel crushed rocks；When independent swing mechanism or backward stroke of the piston, band
Dynamic drill steel and bore bit turn round certain angle.Continuous impact, revolution make drill steel and bore bit dig out circular blasthole on rock.
Rock drill drives drill steel and bore bit to dig broken rock powder and need to inject water into circular blasthole by drill steel and bore bit
It rushes out.Row's powder water that disclosed hydraulic drill technology has been related to is realized using the high pressure water of backward stroke of the piston
's.The advantages of this technology is realize power single, and pipeline is few.Shortcoming is to utilize the high pressure water of power, the water of this water
Matter requirement is very high, has additive in water, the water into power needs to filter.The mode of this supply and discharge powder water to the wasting of resources very
Greatly, water is constantly added into power set.For this phenomenon, by the on-the-spot investigation to working environment, we have developed
A kind of a kind of power water new hydraulic drill separated with row's powder water arranges powder water feed mechanism.
The content of the invention
The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies of the prior art, provide a kind of power water and row's powder water
Separated new hydraulic drill row's powder water feed mechanism, the confession of the row's of realization powder water give the synchronization of hydraulic drill work
Property, the consumption to high water quality water is reduced, while reduces the waste to water resource.
To solve the above problems, the present invention uses following technical scheme：A kind of new hydraulic drill row's powder water supply
Mechanism including shank body, is provided with extraneous row's powder water water supply mechanism for discharge powder water in shank body, external world's row's powder water water supply mechanism by
Water supply automatic controls control row powder water through and off, water supply automatic controls by control spool be opened mechanism drive
It is dynamic.
It is further optimization of the present invention to said program below：The control spool mechanism that is opened is fixed including rear end
Close to the sebific duct of back-end location in shank body, the front end of shank body and the rear end of cylinder body are coaxially assembled.
Further optimization：It offers to connect the shank body high pressure that sebific duct supplies automatic controls with water in the shank body
Water inlet opening.
Further optimization：The front end of the sebific duct is fixedly mounted on the one side of cylinder body, and passes through cylinder body high pressure water water outlet
It is communicated with the cylinder body undercut opened up in the middle part of cylinder body.
Further optimization：It is the cylinder body high pressure in cylinder body undercut to be coaxially equipped in the cylinder body in drawback movement
Water water outlet provides the piston of high pressure water.
Further optimization：Water supply automatic controls includes the valve body for being coaxially assemblied in shank body rear end, in valve body
The coaxial control spool for being equipped with control row's powder water through and off.
Further optimization：The control spool is controlled in figure apparent place being formed when putting between the front end face and valve body of its large diameter portion
High-pressure water chamber between spool and valve body processed.
Further optimization：It is provided on the valve body multiple for high-pressure water chamber and shank body between connection control spool and valve body
The high pressure water of high pressure water inlet opening enters valve body inlet.
Further optimization：The rear end of the valve body is coaxially equipped with nitrogen valve body, and being coaxially equipped in nitrogen valve body can be with
The nitrogen valve of reciprocating movement.
Further optimization：The valve body is fixedly mounted close to the position of nitrogen valve body front end is useful for limitation nitrogen valve movement
Resilient key.
When the present invention does not start shooting, outside water enters row's powder water by water pipe head and enters valve body inlet and water storage cavity,
Control spool front end seals up valve body water outlet；
When the present invention starts shooting work, the high pressure water of cylinder body undercut enters control by cylinder body high pressure water water outlet through sebific duct
Nitrogen pressure is overcome to be moved after promoting control spool between spool and valve body in high-pressure water chamber, powder water is at this moment arranged and enters valve body water outlet
It enters back into out in liquid drugs injection, then the osculum on drill steel centre bore and bore bit by being communicated with going out liquid drugs injection is injected water into blasthole
Rock powder is rushed out；
When the present invention is stopped, the high-pressure water pressure at cylinder body undercut is reduced to zero, the control valve under the action of nitrogen
Core movement blocks water stream channel and stops supplying water, and in hydraulic drill normal work, the hydraulic pressure in cylinder body undercut is height
Pressure Xun Huan, the open and close for correspondingly controlling spool is also synchronously to cycle, the row's of thereby realizing powder water discontinuous cycle
Supply, that is, supplies water during backward stroke of the piston, and when stroke does not supply water.
By setting, extraneous row's powder water water supply mechanism, water supply automatic controls to the present invention and control spool is opened machine
Structure realizes the online of water and automatically feeds, and to water quality no requirement (NR), solving needs to add additive in water and water need to be carried out
The problem of filtering, while the use of ancillary equipment is decreased, Drilling cost is reduced, interruption is supplied for discharge powder water and Xun Huan
High pressure water can save 50% water.
The invention will be further described with reference to the accompanying drawings and examples.
