Description
Technical field
It the utility model is related to drill hammer technical field, and in particular to a kind of gravity that material device is carried with spiral terrace
Drill hammer and percussive drill.
Background technology
Drilling well refers to stratum is drilled into eyelet from ground using plant equipment or manpower, and in drilling process, rig is to bore
An essential equipment in well work, rig generally includes drill bit and hoist engine etc., according to the difference of drilling method, rig
It can be generally divided into percussive drill and slewing drilling machine.
Slewing drilling machine mainly using rotation mode, by drill bit in depth under, the outer surface of drill bit forms spiral, is boring
During head declines, soil is constantly transported to earth's surface by spiral.Slewing drilling machine has drilling efficiency height, drilling depth big
The advantages of, therefore be widely used in plains region.But rotary drilling is because the entirety of drill bit is in contact with soil, therefore
Loss of the which to drill bit is very big, in the ground consisting of hard rock region such as mountain region, needs often more bit change using slewing drilling machine, causes
Construction speed is slow, and construction cost is higher.Therefore, percussive drill is often used in ground consisting of hard rock region, percussive drill needs
Repeatedly rise and drop impact drill bit, constantly impact stratum downwards by drill hammer and carry out broken rock.
In modern ram drilling process, mud is widely used, in drilling operation, mud is filled in the borehole, can be with
Prevent collapse hole and by suspension of cuttings in mud.Wherein suspension landwaste can prevent landwaste from sinking to bottom hole quickly, prevent burying thing
Therefore；In the prior art, also carry out the work of landwaste cleaning using the function of mud suspension landwaste simultaneously.However, due to punching
Hit rig and constantly reciprocate through slurry liquid at work, stirred mud so that the landwaste being broken is in certain aspect
It is evenly distributed in mud, but distribution density gradual sparse rule is from bottom to top present.When the concentration of cuttings in mud carries
Gao Houhui causes mud to produce larger resistance to the whereabouts of drill hammer, reduces impulsive force of the drill hammer to rock stratum.
The settling mode of prior art is after the predetermined operation time is crept into, and lifts impact drill, then carry out landwaste cleaning
Work.Due to needing to stop drilling work in landwaste scale removal process, therefore such mode drilling efficiency is relatively low.
To solve the above problems, Chinese patent literature CN205172427U discloses a kind of well-digging equipment, including hook, sky
The heart bores bucket and hollow boring bit, including hook, core drill bucket and hollow boring bit, and hook is arranged on core drill bucket top, hollow boring bit
Installed in core drill bottom of the barrel, check valve is provided with described core drill bucket bucket.The technical scheme can be in the process of drilling
In, while collect the landwaste being suspended in mud.But because landwaste has the proportion bigger than mud in itself, therefore also cause
Landwaste in core drill bucket is entered every time by can make after cover plate carrying one section of height of lifting of check valve in gravity by check valve
Sink gradually downward under, and lifted again encountering cover plate next time.So overstock on work a period of time back shroud
Landwaste can prevent cover plate from opening the function forfeiture for collect landwaste.At this moment the well-digging equipment can only being proposed integrally to, well head is carried out
Cleaning.This process still occupies certain working time, and harmful effect is produced to drilling efficiency.
Utility model content
