Part and belt-conveying part, rake rock broken rock part, hydraulic pressure and operating system and body platform；The integral machine also has whitewashing to fill
Put and pedestal；Described pushes away the front that cash is mounted in the track unit with rake rock shovel board, and belt conveyer is arranged on shovel board
Rear and crawler travel portion centre；Described hydraulic pressure and the body platform of top of the operating system loaded on track unit
On；Described pedestal is fixed on the front middle part of body platform, and described rake rock broken rock piecemeal activity is connected on pedestal, and described
Refractory gunning equipment be loaded on broken rock pneumatic hammer side.
Described rake rock broken rock part includes cantilever arm, cantilever arm oil cylinder, swing arm, boom cylinder, broken rock hammer device；It is described
Swing arm centre and cantilever arm hinge, on top and cantilever arm of the boom cylinder loaded on swing arm；Cantilever arm oil cylinder
On cantilever arm lower section and described pedestal, described broken rock hammer device is loaded on the lower end of swing arm.
Although the broken shipment spray integral machine of stone drifting realizes large, medium and small rock roadway in coal mine driving broken rock rake rock, detritus fortune
Defeated, wet shotcrete mechanicalization.But, existing impact grinding rock gangway digs machine only one of which quartering hammer, single-point rock fracture in dynamic indentation, broken rock effect
Fruit and operating efficiency are relatively low, fail to carry out omnibearing stereo pattern work for rock gangway；Particularly at clear bottom and when repairing side, clear bottom
And repair side effect it is poor, cost the time it is long, have impact on the headwork efficiency of complete machine.
The content of the invention
It is contemplated that overcoming the shortcomings of that existing stone drifting, can be for rock gangway there is provided a kind of rock breaking efficiency is relatively good
Carry out omnibearing stereo pattern work, clear bottom and repair side effect it is good, headwork efficiency is higher.
For achieving the above object, the technical scheme is that：
A kind of three hammer body impact grinding devices of rock gangway rock tunnelling bolting combined machine, including quartering hammer group 401, telescopic oil cylinder 402, lifting
Arm 405, support cylinder 406, revolving bed 407 and angling cylinder 408, it is characterised in that：Also include adjustment oil cylinder 403, outer sleeve
404；Described quartering hammer group is connected by three independent drill steels with hammer body clamping plate by high-strength bolt respectively；
Described quartering hammer group both sides respectively equipped with one group of semicircle column type guide pillar, quartering hammer group by with telescopic oil cylinder together with
Outer sleeve is connected, and by being installed on semicircle column type guide pillar, guide pin bushing two groups of friction pairs of formation therebetween, outer sleeve passes through broken
Broken hammer group fulcrum post is connected with lifting arm formation pin pair；Quartering hammer group is driven to carry out under telescopic oil cylinder effect elastic,
And promote the drill steel of quartering hammer group to move forward, insert stone drifting working face；
Described adjustment oil cylinder is respectively mounted with outer sleeve, lifting arm between the two, can be made in the presence of adjustment oil cylinder
Quartering hammer group is overturn up and down；
Described lifting arm is connected with revolving bed by revolving bed pin-shaped into pin pair；One end dress of described support cylinder
In revolving bed bottom, the other end is connected with lifting arm bottom；Lifting arm upper and lower can be overturn in the presence of support cylinder；
Described impact grinding portion is entirely fixed on unit body by revolving bed and revolving support, described revolution oil
Cylinder one end is connected with revolving bed, and the other end is connected with unit body；It can be rotated in the presence of described angling cylinder to side.
The present invention substantive distinguishing features and significant effect be：
By three quartering hammer stereoeffects and separate unit independent control, the problem that rock gangway mechanization is abolished is solved,
Above and below being carried out to the broken rock angle of quartering hammer, left and right flexible modulation, make it that drill steel stress is more reasonable during impact operation, impact cutting
Rock works well, and can extend the service life of quartering hammer, and clear bottom to tunnel and repaiies side operation, can reduce driving, clear bottom
And repair the side time, so as to improve the drivage efficiency of complete machine.
