Specific implementation mode
Below in conjunction with the accompanying drawings, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Refering to fig. 1-2, a kind of excavator is cut with broken, including hydraulic cutting device 1 and hydraulic pressure hammering device 2;The liquid
Compression shear cutting apparatus 1 includes that shell 11, lower jaw cut 12, maxilla and cut 13 and oil cylinder 14, and the maxilla cuts 13 settings in 11 front of shell,
Lower jaw, which cuts 12 and is correspondingly arranged at maxilla, to be cut under 13 and hinged with shell 11, and 14 one end of oil cylinder is hinged on shell 11, the other end
12 rear ends are cut with lower jaw and hingedly form triangular structure, and housing rear end is provided with the engaging lug 111 for being connect with excavator;Liquid
Pressure hammering device 2 includes the jump bit 24 of leading portion protrusion, for the rear row buffering device 21 of row buffering after jump bit 24, drives liquid
The flexible fluid pressure drive device 22 of hammer and hammering protective device 23, the rear row buffering device 21, fluid pressure drive device 22, hammer
It hits protective device 23 and jump bit 24 is sequentially connected setting;
In use, the excavator of the utility model with it is broken cut by engaging lug 111 accordingly respectively with the bucket of excavator
Bar and bucket cylinder are hinged as digger operating device, to become in the flexible triangle edges for causing it to be constituted of oil cylinder 14
Change and drive lower jaw to cut 12 and cut 13 foldings to realize cutting reinforcing bar relative to maxilla, be that power is big using hydraulic advantage, work is steady
It is fixed;The jump bit 24 of hydraulic pressure hammering device 2 can repeatedly stretch under the driving of fluid pressure drive device 22 hammers target object, rear row
The fluid pressure drive device 22 that buffer unit 21 and hammering protective device 23 have protection driving jump bit 24 flexible acts on, and increases and digs
Pick machine cuts service life with broken.
Row buffering device 21 in rear row buffering cylinder body 211, rear row buffering cylinder body 211 including being provided with damper piston after described
212, filling gas 213 is provided in the closed gap that rear row buffering cylinder body 211 and damper piston 212 are constituted;The hydraulic pressure drives
Dynamic device 22 includes drivig cylinder 221, is provided in drivig cylinder 221 and drives piston 222, driving cylinder with casing wall blind-mate
221 liang of tail portions of body are respectively arranged with pouring orifice 2211, are provided at both ends with end cover 223;23 device of hammering protective device
Cylinder body 233 is hammered, hammers in cylinder body 233 and is provided with first piston 231 and second piston 232, is connected and is buffered by piston rod 112
Piston 212, driving piston 222 and first piston 231, second piston 232 connect jump bit 24, are provided with after second piston 232
Resetting spring 234, first piston 231, second piston 232 and hammering cylinder body 233 in be provided with filling gas 213;
Hydraulic oil can come in and go out from pouring orifice 2211 respectively to drive driving piston 222 flexible, and hammering work is cut due to broken
Drive 222 stretching frequency of piston height, power big when making, row buffering cylinder body 211 after being thus arranged before setting fluid pressure drive device 22, after
The extruding that filling gas in row buffering cylinder body 211 can be retreated with damper piston 212 generates buffering drag, protection driving piston
Sealing cover 223 after clashing when will not be retreated when 222 work;Hammer protective device 23 setting fluid pressure drive device 22 it
Afterwards, hammer the filling gas in protective device 23 equally has preceding Shen cushioning effect to driving piston 222, it is often more important that by piston
Bar 112 and jump bit 24 separate, and hammering is that the gas 213 of filling a vacancy between first piston 231 and second piston 232 forms gas
Pad, avoids directly hitting, and has both protected fluid pressure drive device 22 from impact, ensures that excavator cuts performance with broken, increases
It has grown excavator and has cut service life with broken.
The filling gas 213 is nitrogen, the chemical property torpescence of nitrogen, be difficult under room temperature occur with other substances it is anti-
It answers, and it is little to obtain difficulty, is ideal filling gas.
The maxilla cuts 13 shear blades and is serrated;Advantage is in shear reinforcement, especially while when more of shearing,
Zigzag shear blade, which has, keeps reinforcement location effect, makes that there is no can't cut or reinforcement location sliding phenomenon.
Cutting blade end is provided with the curved arc angle 121 that raises up before the lower jaw cuts 12;End, which is provided with the curved arc angle that raises up, makes excavation
Machine with it is broken cut shearing work when lower jaw cut 12 raise up snap-action when maintain a kind of trend of reinforcing bar of collecting, make reinforcing bar will not
It runs out of except jaw.
It is cut with broken using the excavator of the utility model, is torn open as digger operating device and for buildings such as high towers
It removes, both can very easily be crushed lump structure, also, reinforcing bar can be cut when encountering reinforcing bar and hindering one's work, exclude to interfere
Afterwards and work on.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
