Description
Technical field
It the utility model is related to field of mining, and in particular to a kind of coal mine down-hole drilling coal sample extraction element.
Background technology
Coal is the important basic energy resource in China, since " 12 " are planned, has accelerated Coal Green exploitation, cleaning profit
With, it has been normality, and for the severe situation in current colliery, cost efficiency is even more the most important thing in working.From 2012 to
The present, although the accident rate in progress of coal mining has declined, the generation of any accident can not all despise, and can all give existing
Last layer frost is covered in gloomy coal mining enterprise, the harm of especially coal and gas prominent accident is the most serious in coal mining accident.
It is a crucial step to carry out coal and gas outburst prominent controlling work, and the validity for protruding preventing and controlling depends on coal and gas prominent
The accuracy of prediction, while the accuracy key of Coal and Gas Outbursts Prediction is that prediction index measured value is needed accurate and can represented
Soft layering in coal seam.
《Prevent and treat coal and gas prominent regulation》Article 13 provides that projecting coal bed identification should be according to the coal seam of practical measurement
Maximum gas pressure P, the soft layering Failure type of coal, the index such as solid coefficient f of the gas diffusion initial speed Δ p of coal and coal
Identified.《The solid coefficient assay method of coal》（MT49—1987）Preferably 20 ~ 30mm coal sample block is mentioned in standard
It is measured f values；《Coal seam gas-bearing capacity underground Direct Determination》（GB/T23250—2009）Regulation is new sudden and violent in standard
Preferred coal core sampler is answered in the coal road of dew, and whether column coal core or powdery coal core will reject the coal of the part containing spoil
Sample.
Patent at present about drilling extraction coal sample has a lot, and most of sampling theorems are all that drill bit is cut using blast
The ickings fallen is blown into the sampler space, such as：A kind of 2 months 2015 Chinese patents disclosed in 25 days " new drilling coal sample sampler "
（Application number：201420442884.1 grant number：CN204175294U）, the sampler is mainly made up of drill bit, sleeve pipe, drilling rod,
Sampling theorem is that drill bit cuts coal body powdering, and coal dust is blown into the sampler space by blast.Due to the sampler space be sleeve pipe with
This just significantly limit taken coal sample amount for space between drilling rod, in addition it is lower take coal sample to hole when, due under the sampler space
End does not prevent the auxiliary equipment that coal sample falls, and during brill is moved back, takes coal sample to be easy to drop, while be only limitted to take coal
Bits, and the deficiency of ickings maximum is to be difficult to reject spoil particle therein.Sampler principle also is complicated, this adds increased
The unreliable degree of device, in use once there is some part to go wrong, sampling just failure.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provide it is a kind of it is simple in construction, easy to use, cost is cheap
A kind of coal mine down-hole drilling coal sample extraction element, it is mostly bulk that it, which takes coal sample, is easy to reject spoil part, ensure that coal sample
Purity, and can meet that underground is soft or the needs of all kinds of drillings extraction coal sample in hard coal body.
The utility model is achieved through the following technical solutions：A kind of coal mine down-hole drilling coal sample extraction element, including
Enter coal cylinder, enter coal neck and coal-storage cylinder, enter coal neck, enter coal cylinder and coal-storage cylinder and be sequentially threadedly coupled and communicate；Enter coal cylinder and enter coal
Vane cutter tooth is circumferentially provided with the section at end；Entering to be provided with coal neck can make opening into coal neck inner chamber and closing it
Between the elastic baffling device changed；Coal-storage cylinder is connected with drill rod thread.
It is described enter coal cylinder length determined according to coal is thick；The length of the coal-storage cylinder is according to the coal amount to be extracted
It can be adjusted.
The elastic baffling device is made up of multiple equal-sized fan-shaped shell fragments, and the radius of the shell fragment is with entering coal neck
Radius it is equal, the arc-shaped side of each shell fragment is connected with entering coal neck, and the center of circle is pointed into coal neck center.
The preferred vane shape of shell fragment, and be in close contact between every vane shape shell fragment, coal can be encapsulated into after installation
Neck.
It is described enter coal cylinder coal exit set internal thread；Enter coal neck enter coal end and coal exit is respectively equipped with external screw thread；Storage
Coal cylinder enters coal end and is provided with internal thread, and coal-storage cylinder outer end is connected with the bolt for jointed rod；It is described enter coal cylinder, enter coal neck and
Coal-storage cylinder is connected through a screw thread.
Compared with prior art, the utility model package unit is simple in construction, is divided into three parts, is easy to dismounting to take out coal
Sample；Cost is cheap, and can meet that underground is soft or the needs of all kinds of drillings extraction coal sample in hard coal body, while taken coal sample is mostly
Bulk, it is easy to reject spoil part, ensure that the purity of coal sample；Size and required coal of the ore deposit root according to drilling can particularly be made
The size of sample amount is processed.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of coal mine down-hole drilling coal sample extraction element, including hollow-core construction enters coal cylinder 2, enters coal neck
8 and coal-storage cylinder 10, it is described enter coal cylinder 2 coal-feeding end section be circumferentially provided with cutter tooth 1 and be used to cut coal body, set screw channel in coal exit
3；Enter coal neck 8 enter coal end and coal exit is respectively equipped with external screw thread 4,9, enter in coal neck 8 be provided with can make in coal neck 8
The baffling device 5 that chamber is changed between opening and closing；Coal-storage cylinder 10 enters coal end and is provided with screw channel 6, and the outer end of coal-storage cylinder 10 is connected with
Bolt 7 for jointed rod；It is described enter coal cylinder 2, enter coal neck 8 and coal-storage cylinder 10 is sequentially connected with, and in communicating after connecting
State.
As shown in Fig. 2 the baffling device 5 is made up of multiple equal-sized fan-shaped shell fragments, the radius of the shell fragment with
Enter that the radius of coal neck 8 is equal, the arc-shaped side of each shell fragment and enter coal neck 8 and be connected, the center of circle is pointed into the center of coal neck 8.It is described
The preferred vane shape of shell fragment, and be in close contact between every vane shape shell fragment, coal neck 8 can be encapsulated into after installation.
The use of process is when drilling rod gets to coal seam, takes out drilling rod, lay down drill bit, load onto the present apparatus.The present apparatus with brill
Bar is sent into drilling, starts to creep into when being sent to coal seam, and at this moment the just fly-cutting coal body of vane cutter tooth 1, is cut away by vane cutter tooth
The coal body not destroyed strongly just enters coal cylinder 2, and with further drilling, coal body is reached into coal neck 8, passes through device
Before push away, constantly there is coal body to be extruded toward coal cylinder 2 is entered, cause the vane shape shell fragment opening into coal neck 8, coal body enters coal-storage cylinder 10.
When coal body is full of coal-storage cylinder 10, drilling rod is exited, the vane shape shell fragment that coal neck 8 is entered during drilling rod exits can be because extruding
The disappearance of external force, quick-make, and then exiting with drilling rod, coal sample is extracted.
Package unit is simple in construction, easy to use, cost is cheap, and can meet that underground is soft or hard coal body in all kinds of drillings
The needs of coal sample are extracted, while taken coal sample is mostly bulk, is easy to reject spoil part, ensure that the purity of coal sample.
