Background technique
Rock is a kind of natural uneven material, includes stratification and soft layer, so taking to the uneven material such as rock
When core, usually can there is a situation where core along joint layer and Weak face be broken, core fracture after, the core of fracture and rubble meeting
It runs at high speed in drill bit tube wall, when drill bit shuts down, the core and rubble of fracture have deviated from original rupture location, and
It can occur to accumulate and squeeze between drill bit inner wall, fracture core, rubble at this time, the effect of power be generated, so that core can not edge
Tube wall normally slide, if convention resolution method is to tap tube wall or den bohrkopf abbauen with hard object at this time, the above method is short
It is difficult to take out the core and rubble of fracture in time, or even will cause tube wall deformation, irreversible injury is caused to drill bit and waste
Plenty of time.In practical location of the coring procedure, existing drill bit can not observe practical coring length in drill bit, operator often with
Experience controls the time that corning machine stops drilling with feeling, will cause the waste of rock in this way, once the rock sample in drill bit connects
The upper top surface for contacting drill bit will cause very big injury, even safety accident for drill bit even corning machine.
Summary of the invention
To overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of efficient, time saving, easy to operate, safe
Rock coring bit.
The rock coring bit of the utility model include freewheel clutch, drill main body, more than one spring, pressing plate,
Graduator, freewheel clutch are arranged at the top of drill main body, i.e. the outer ring of freewheel clutch is fixed on drill main body inside top,
Water inlet is fixed on the inner ring upper end of freewheel clutch, and spring one end is fixed on the inner ring lower end of freewheel clutch, the other end with
Pressing plate is connected, and graduator passes through outer ring setting and is provided with assembly and disassembly slot in drill main body, on water inlet, and drill main body bottom end is provided with
Blade is provided with through-hole on pressing plate.
The graduator is the bar with convex block, and the outer ring that bar passes through freewheel clutch is arranged in drill main body, convex block
It is placed in above outer ring, convex block is magnet block, can be adsorbed on drill main body.
The drill main body is hollow cylinder.
The freewheel clutch further includes star-wheel, and 3 or more balls are arranged on star-wheel by spring spindle, ball with
Outer ring inner wall is fitted close, and inner ring is arranged in outer ring by star-wheel.
The blade is diamond annular blade, and blade outer diameter is bigger than the outer diameter of drill main body.
Freewheel clutch can be replaced bearing in the present apparatus, and outer race is fixed on drill main body inside top, water inlet
It is fixed on the inner ring upper end of bearing, spring one end is fixed on the inner ring lower end of bearing.
The drill main body lower part of the present apparatus is provided with more than one hole, and for assisting coring, hole is ellipse.
The present apparatus is in use, spanner is placed on assembly and disassembly slot, by water inlet on corning machine, water flow can be from water inlet
With in the inner ring of freewheel clutch (bearing) flow into drill main body in and form column water flow；By spring and pressing plate apply to
It pushes to try hard to keep and demonstrate,proves the relative position of coring rock sample and do not change, and then prevent the generation of bit freezing；Pass through the convex block on graduator
The variation of relative position judge practical coring length, i.e. pressing plate jacks up the bar of graduator, determines whether to stopping coring.
The beneficial effects of the utility model are: spring-the pressing plate and addition freewheel clutch that pass through rock coring bit
The design of (or bearing) shortens the coring time, reduces the use injury to drill bit, and the time for wasting bit freezing is controlled
System, extends the service life of drill bit；Changed by the relative position of graduator and judges practical coring length, coring is visual
Change, reduces the risk of accident generation；The utility model coring is efficient, saves the time, easy to operate, small to drill bit injury, peace
Quan Xinggao, more fitting scientific research and safety in production are practical.

Specific embodiment
The utility model is described in further detail below by embodiment, but the protection scope of the utility model not office
It is limited to content of counting.
Embodiment 1: as shown in Figure 1-3, this rock coring bit include freewheel clutch 2,3,1 springs 4 of drill main body,
Pressing plate 5, graduator 8, wherein freewheel clutch 2 is set including 10,4 star-wheel 12, outer ring 9, inner ring balls by spring spindle 13
It sets on star-wheel, ball and outer ring inner wall are fitted close, and inner ring 10 is arranged in outer ring 9 by star-wheel；Drill main body 3 is hollow
Cylindrical body；The setting of freewheel clutch 2 is fixed in drill main body top in 3 top of drill main body, the i.e. outer ring of freewheel clutch 2
