Abstract
The utility model discloses a drilling cuttings gathering device used for a drilling cuttings method for predicting rock burst, comprising a housing; wherein a hole sealing sleeve is inserted into a front wall of the housing, a rear wall of the housing is provided with a sleeve hole in which a drilling rod is inserted, the housing is provided with an annular hairbrush therein, centers of the sleeve hole, the annular hairbrush, and the hole sealing sleeve are on the same axis, a top surface of the housing is provided with a skylight with a cover, a bottom surface of the housing is provided with a funnel, and a gathering bag is sleeved on the funnel. The drilling cuttings gathering device of the utility model avoids nickings loss and air pollution caused by the flying nickings, and completely gathers the nickings, thus a high accuracy for predicting the rock burst is achieved.
Description
Technical field
The utility model relates to the collector for bore cuttings that predicting rock burst drilling cuttings method is used.
Background technology
In China, along with the increase of mining depth and the continuous expansion of limit of mining, the harm of each large colliery generation rock burst of the whole nation will be more outstanding.At present, under the forecasting coal mine, rock burst detection method commonly used has drilling cuttings method, electromagnetic radiation method and micro seismic monitoring method etc., because rear both input costs are larger, and can not be specific to the detection method of certain position, it is simple that the drilling cuttings method has construction, the workman easily grasps, and brings into play great role in impacting the area monitoring.
At present, when Coal Miners was used drilling cuttings method predicting rock burst, a common bag of cement commonly used etc. was layered on the place and collects ickings, and then weighing.This kind operating type not only easily causes ickings to wave everywhere, affects operating worker healthy, and in the process of waving, and easily causes ickings to run off, can't complete collection ickings, cause forecasting inaccuracy.
The utility model content
In order to solve in the drilling cuttings method ickings problem of waving, the collector for bore cuttings that a kind of predicting rock burst drilling cuttings method of the utility model design is used everywhere.
The technical scheme that the utility model is taked is:
The collector for bore cuttings that a kind of predicting rock burst drilling cuttings method is used, it is characterized in that, it comprises a housing, the antetheca of housing inserts a sealing of hole cover, is provided with the trepanning of insertion drilling rod at the rear wall of housing, is provided with annular hairbrush in housing, the center of trepanning, annular hairbrush and sealing of hole cover on an axis, the end face of housing is provided with skylight with cover, and the bottom surface of housing is provided with funnel, and on funnel, cover has collecting bag.
For collector for bore cuttings is located, be provided with two adjustable supporting legs below housing.
In order to make two supporting leg universal adjustment, supporting leg by bearing be arranged on housing below.
For collector for bore cuttings is located, be provided with two hooks on housing, can be suspended on the rib entanglement and effectively fix.
For being applicable to down-hole coal bed different angle, the collector for bore cuttings front end face adopts the sphere design, can effectively be applicable to the coal seam, inclination angle of-30 ~ 30 °.
During use, at first carry out prebored hole with rig on rib, then with the sealing of hole inserting man-hole opening of gathering-device front portion, position with adjustable supporting leg, the drilling rod that inserts with drill bit can creep into, and the drilling cuttings of generation is collected in housing.When drill bit is extracted out from housing, can be by the ickings on annular brush cleaning drilling rod, and open subsequently the skylight and empty collecting chamber, accomplish all effectively to collect ickings.Carry out weighing after collecting with collecting bag.
The ickings that this gathering-device has been avoided ickings to wave everywhere and caused runs off and air pollution, and ickings is collected fully, and the predicting rock burst accuracy is high.

Fig. 1 is structure and the state of the use front view of the utility model embodiment.
In figure, 1-trepanning, 2-annular hairbrush, 3-housing, 4-skylight, 5-sealing of hole cover ,-6-funnel, 7-supporting leg, 8-collecting bag, 9-drilling rod, 10-rib, 11-globe bearing, 12-hook.
Embodiment
As shown in Figure 1, the collector for bore cuttings that a kind of predicting rock burst drilling cuttings method is used, it comprises a housing 3, the antetheca of housing 3 inserts a sealing of hole cover 5, is provided with the trepanning 1 of insertion drilling rod 9 at the rear wall of housing 3, is provided with annular hairbrush 2 in housing 3, the center of trepanning 1, annular hairbrush 2 and sealing of hole cover 5 on an axis, the end face of housing 3 is provided with skylight with cover 4, and the back of housing 3 is provided with funnel 6, and on funnel 6, cover has collecting bag 8.
For collector for bore cuttings is located, be provided with two supporting legs 7 below housing 3.
In order to make two supporting leg 7 universal adjustment, supporting leg 7 is arranged on housing 3 by globe bearing 11.
For collector for bore cuttings is located, be provided with two hooks 12 on housing, can be suspended on the rib entanglement and effectively fix.
For being applicable to down-hole coal bed different angle, housing 3 front end faces adopt the sphere design, can effectively be applicable to the coal seam, inclination angle of-30 ~ 30 °.
During use, at first carry out prebored hole with rig on rib 10, then the sealing of hole cover 5 of gathering-device front portion is inserted the aperture, with supporting leg 7, gathering-device is positioned, insertion can be crept into the drilling rod 9 of drill bit, and the drilling cuttings of generation is collected in housing 3.When drill bit is extracted out from housing 3, can be by the ickings on annular hairbrush 2 cleaning drilling rods 9, and open subsequently skylight 4 and empty collecting chamber, accomplish all effectively to collect ickings.Carry out weighing after collecting with collecting bag 8.
