Abstract
The utility model discloses a kind of drilling sampling device.This drilling sampling device, comprise drilling rod, drilling rod lower end is threaded with fittings body, fittings body is threaded with the headkerchief of below, is connected below headkerchief by basket with drill bit, is provided with the through hole be communicated with basket with drilling rod in the middle part of fittings body, the internal diameter of this through hole is up big and down small, steel ball is positioned in this through hole, effectively blocks flushing liquor in drilling rod and, to the pressure effect of rock sample in core barrel, improve rock sample taking rate when sampling pulls out of hole.Be applicable to geological drilling single action single tube carbide alloy, diamond drilling sampling.Have that structure is simple, low cost of manufacture, simple to operate, reliable operation, the advantage such as increase work efficiency suitable with conventional boring tool material.
Description
Technical field
The utility model relates to a kind of geological drilling device, especially relates to a kind of drilling sampling device.
Background technology
In geological drilling process, the normal single action single tube method that adopts carries out drill sampling, namely when creeping into drill hole sampling depth location, adopting and throwing in the methods such as steel ball in drilling rod, drilling tool in hole is taken out ground, take out rock sample in drilling tool.In sampling process, often because of effects such as sediment depositions in flushing liquor, the steel ball of input is blocked in ball seat, joint need be removed, rock sample could take out by headkerchief; Sometimes because operating personnel's error is not when steel ball takes out, send water push rock sample or creep into, water pump, circuit failure or damage can be caused, increase operating personnel's labour intensity, have influence on probing operating efficiency.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of efficient drilling sampling device easily.
In order to realize foregoing invention object, the technical scheme that the utility model adopts is:
A kind of drilling sampling device, comprise drilling rod, drilling rod lower end is threaded with fittings body, fittings body is threaded with the headkerchief of below, be connected with drill bit by basket below headkerchief, be provided with the through hole be communicated with basket with drilling rod in the middle part of fittings body, the internal diameter of this through hole is up big and down small, and steel ball is positioned in this through hole.Steel ball is connected with the body of rod or rope body, falls in fittings body by through hole, change place of blocking through hole internal diameter.
The utility model compared with prior art, has the following advantages:
A kind of drilling sampling device, have that structure is simple, low cost of manufacture, simple to operate, reliable operation, the advantage such as increase work efficiency suitable with conventional boring tool material, be applicable to geological drilling single action single tube carbide alloy, diamond drilling, drillability less than six grades ground earth-boring samplings.
Adopt this drilling sampling device, when drilling tool in hole proposes ground, by being exposed at the body of rod outside fittings body or rope body conveniently takes out steel ball, carry out sending water to push rock sample, avoid because in flushing liquor, steel ball is blocked in ball seat by sediment deposition effect, joint need be removed, trouble that headkerchief brings, reduce labor intensity.
Adopt this drilling sampling device, express effect by what connect the body of rod of steel ball or rope body, reliably can prevent people from being the generation of maloperation, reduce drilling equipment fault and impact, improve probing operating efficiency.
Accompanying drawing explanation
Fig. 1 is drilling sampling device structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of drilling sampling device, comprise drilling rod 3, drilling rod 3 lower end is threaded with fittings body 2, fittings body 2 is threaded with the headkerchief 4 of below, is connected below headkerchief 4 by basket 5 with drill bit 6, is provided with the through hole be communicated with basket 5 with drilling rod 3 in the middle part of fittings body 2, the internal diameter of this through hole is up big and down small, and steel ball 1 is positioned in this through hole.Steel pole 11 is welded with above steel ball 1.
