Description
Technical field
The invention belongs to the drill steels that quartering hammer technical field more particularly to a kind of band remove function.
Background technology
At present the drill steel of quartering hammer can only impacting object, keep object broken, in actual mechanical process, be crushed
It can make drill steel that can not accurately aim at break-up point if stone is not cleaned up in time, be hit next time；When object
When being crashed to pieces, precursor and main body loosened screw can be caused and be damaged by being further continued for hitting, and engineering machine can be also undermined under serious situation
Tool body；If when crushing operation carries out, attempt to rock drill steel using to clear up broken stone, main body screw will with drill steel
There is the possibility of rupture.
The present invention design a kind of drill steel of band stripping function solve the problems, such as it is as above.
Invention content
To solve drawbacks described above in the prior art, the present invention discloses a kind of drill steel of band stripping function, it be use with
Lower technical solution is realized.
A kind of drill steel of band stripping function, it is characterised in that：It include triggering plectrum, stripping film, stripping head, drill steel shell,
Drill steel head cover, bearing rod, bearing rod resetting spring, the first snap ring, the second snap ring, stripping energy-stored spring, third snap ring, bearing rod
Set, fixed ring, stripping push rod, card hole, stripping mounting hole, stripping film shaft, slide key, mounting hole, sliding groove, clamping lock fixture block,
Clamping lock resetting spring, push rod revolute pair, fixture block locating part, fixture block sliding slot, plectrum chute, locating part sliding slot, wherein drill steel shell
Top is equipped with drill steel head cover, and the bottom end of drill steel shell is equipped with stripping head, bearing rod is equipped with inside drill steel shell；Drill steel head cover,
Bearing rod resetting spring, the first snap ring, the second snap ring, stripping energy-stored spring, third snap ring are sequentially arranged at load from top to bottom
On bar, the first snap ring and the second snap ring are fixed on bearing rod, and third snap ring is mounted on load rod set top, and bearing rod resets bullet
Spring is mounted between drill steel head cover and the first snap ring, and stripping energy-stored spring is mounted between the second snap ring and third snap ring；Load
The lower end of bar is symmetrically installed there are two slide key, opens to the internal symmetry of load rod set that there are two sliding groove, bearing rod lower ends
In load rod set, slide key slides in sliding groove；The bottom end of load rod set is equipped with fixed ring, and fixed ring is circumferentially equal
Even to open there are four mounting hole, four identical stripping push rods are mounted below fixed ring, and push rod is removed for any one,
Its one end is mounted on by circular hole on the mounting hole hole wall of fixed ring, and the other end is mounted on by push rod revolute pair in stripping film
Side；There are four stripping films, and four stripping films are identical pentagon, and for any one stripping film, it passes through stripping film
Shaft is mounted on stripping head, is opened on stripping head there are four identical stripping mounting hole, the stripping mounting hole bottom of stripping head
End inside is opened there are four card hole, and fixture block sliding slot is provided on the inside of stripping film, and clamping lock resetting spring is mounted in fixture block sliding slot, clamping lock
Resetting spring one end is equipped with clamping lock fixture block, and clamping lock fixture block slides in fixture block sliding slot, and two fixture block locating parts are symmetrically installed
In clamping lock fixture block both sides, the inside of stripping film is opened there are two locating part sliding slot, and fixture block locating part slides in locating part sliding slot, shells
From plectrum chute is provided on the outside of piece, triggering plectrum is mounted on clamping lock fixture block and is stretched out from plectrum chute.
In the present invention, bearing rod stretches out a bit of from drill steel head cover, and impact hammer moves downward can strike drill steel first
In bearing rod, bearing rod moved downward by impact force, and impact hammer strikes drill steel head cover later, and entire drill steel is transported downwards
It is dynamic；During bearing rod moves downward, bearing rod resetting spring is stretched, and stripping energy-stored spring is compressed, and bearing rod is being held
Slide downward in power rod set can will remove pushing away for energy-stored spring by third snap ring, load rod set, fixed ring, stripping push rod
Power is transmitted on stripping film, but since the clamping lock fixture block on stripping film is stuck in card hole, even if stripping film is by stripping push rod
Thrust also can not rotating opening；When drill steel strikes object, the triggering plectrum on stripping head can also strike object, and triggering is dialled
Piece is acted on upward sliding in plectrum chute by power, while the clamping lock fixture block being connected with triggering plectrum is in fixture block sliding slot
Upward sliding, clamping lock resetting spring are compressed, and clamping lock fixture block is removed from card hole, and stripping film is just in the effect of stripping push rod thrust
Under from stripping mounting hole in pop up, at this time remove energy-stored spring elastic force is discharged, stripping push rod can be rotated around fixed ring, at this time
The angle that four stripping push rods open increases, and the stone being broken will be stripped piece and be peeled away from break-up point.Load later
Bar return, the second snap ring can move upwards under the action of bearing rod resetting spring pulling force, and stripping energy-stored spring is stretched, third
Snap ring is driven load rod set to move upwards by the pulling force effect of stripping energy-stored spring, and the angle that four stripping push rods open subtracts
It is small, stripping film is withdrawn into stripping film mounting hole, clamping lock fixture block comes back in card hole.
As being further improved for this technology, above-mentioned fixture block sliding slot, plectrum chute, locating part sliding slot communicate.Due to
Clamping lock fixture block, triggering plectrum, fixture block locating part three are connected, when triggering plectrum upward sliding in plectrum chute, clamping lock
Fixture block upward sliding in fixture block sliding slot, fixture block locating part upward sliding in locating part sliding slot.
As being further improved for this technology, above-mentioned stripping push rod is turned by revolute peace on mounting hole, on bearing rod
When lower movement, stripping push rod can rotate in fixed ring.Stripping push rod is turned out, can be by stripping film from stripping mounting hole
It releases, stripping film is turned out around stripping film shaft；Stripping push rod rotates inwards, and stripping film can be returned to stripping mounting hole
In, stripping film rotates inwards around stripping film shaft.
As being further improved for this technology, the shape of above-mentioned stripping mounting hole is the shape phase of pentagon and stripping film
Together.
Relative to traditional quartering hammer technology, stripping film is installed on the stripping head of drill steel in the present invention, when drill steel is downward
When hitting object, triggering plectrum is moved upwards by the resistance of object, and stripping film is just popped up from stripping mounting hole, will be crushed
Object from break-up point remove；The drill steel in quartering hammer is transformed in the present invention, quartering hammer can be made to exist by stripping film
The object being crushed is removed while broken object, makes break-up point that there is the preferable visual field, there is stronger practical function.
