Description
Technical field
The present invention relates to a kind of adapter sleeve, especially relate to a kind ofly for the adapter sleeve with water cutting function on the mining drill bit, belong to the mine equipment equipment technical field.
Background technology
At present, when in coal mine, constructing, need to use drilling rod to carry out bore operation, and after boring is finished, need earlier drilling rod to be extracted out, send into the water cutter sweep again and expand operation; But, find in actual use, for the unsettled mine in some coal seams, in the process that drilling rod is extracted out, the hole of collapsing easily, thus need the secondary construction, incured loss through delay construction speed; Simultaneously, above-mentioned construction operation step will be holed and reaming separates operation, increase the step of construction greatly, prolong the engineering time, reduce efficiency of construction.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of safe and efficient type mining drill head height setting-out safe and reliable and that efficiency of construction is high to cut adapter sleeve.
The object of the present invention is achieved like this: a kind of safe and efficient type mining drill head height setting-out cutting adapter sleeve, and described adapter sleeve includes housing, and described housing center has vertically a water injection hole, and the front end of described housing connects drill bit, the rear end jointed rod,
The front end of described water injection hole is the setting of step taper hole, the middle part is the cylindrical hole setting, the rear end is the bellmouth orifice setting, there is a piston bush to place in the middle part cylindrical hole of water injection hole, and the front end step taper hole of the conical nose of this piston and water injection hole is complementary, and has an end of a flexible member to link to each other with the front end step taper hole face of water injection hole, and the other end links to each other with the afterbody of piston, obliquely on the shell wall of described housing be provided with a plurality of hole for water sprayings, be equipped with nozzle in the described hole for water spraying.
The safe and efficient type mining drill of the present invention head height setting-out cutting adapter sleeve, described flexible member is the spring that is set on the piston.
The safe and efficient type mining drill of the present invention head height setting-out cutting adapter sleeve is provided with packing ring between described nozzle and the hole for water spraying.
The safe and efficient type mining drill of the present invention head height setting-out cutting adapter sleeve, the afterbody of described piston is set with a back-up ring, and described back-up ring is provided with a plurality of through holes.
Compared with prior art, the invention has the beneficial effects as follows:
After the present invention finishes boring, when extracting drilling rod out, can carry out ream operation, the phenomenon in the hole of therefore can not collapsing, safe and reliable and efficiency of construction is high.

The specific embodiment
Referring to Fig. 1 ~ 3, a kind of safe and efficient type mining drill head height setting-out cutting adapter sleeve that the present invention relates to, described adapter sleeve includes housing 1, and described housing 1 center has vertically a water injection hole 2, and the front end of described housing 1 connects drill bit, rear end jointed rod; The front end of described water injection hole 2 is the setting of step taper hole, the middle part is the cylindrical hole setting, the rear end is the bellmouth orifice setting, there is a piston 3 to be placed in the middle part cylindrical hole of water injection hole 2, and the front end step taper hole of the conical nose of this piston 3 and water injection hole 2 be complementary (water stream channel that both mutual closures can be closed water injection hole 2), afterbody is set with a back-up ring 5, described back-up ring 5 is provided with the back-up ring 5 of a plurality of through hole 5.1(settings and the purpose of through hole 5.1 is, make when current provide hydraulic pressure to piston 3, can guarantee flowing of water stream channel again), there is an end of a flexible member 4 to link to each other with the front end step taper hole face of water injection hole 2, the other end links to each other (preferred with the afterbody of piston 3, this flexible member 4 is for being set in the spring on the piston 3), it is oblique on the shell wall of described housing 1 that to be provided with a plurality of hole for water spraying 6(preferred, the central axis of hole for water spraying 6 becomes 60 ° angle with the central axis of water injection hole 2), be equipped with nozzle 7 in the described hole for water spraying 6, and be provided with packing ring 8 between nozzle 7 and the hole for water spraying 6.
When carrying out normal bore operation, the non-water under high pressure of water in the water injection hole 2 that feeds, at this moment, piston 3 is under the elastic force effect of flexible member 4, the conical nose of piston 3 leaves the front end step taper hole of water injection hole 2, thereby this moment, water can carry out bore operation in normal flow to the drill bit place that housing 1 front end connects;
After boring is finished, when extracting drill bit out, feed water under high pressure to water injection hole 2, at this moment, under the effect of hydraulic pressure, the conical nose of piston 3 is inserted in the front end step taper hole of water injection hole 2 and forms closing structure, thereby has cut off water stream channel, at this moment, water under high pressure can cut ream operation from nozzle 7 ejections of hole for water spraying 6; And the hole for water spraying 6 of oblique setting arranges the ejection current and forms eddy flow, has promoted the water cutting effect;
When drill bit is extracted out, water supply is provided, finished ream operation this moment, therefore saved construction sequence and seen, efficiency of construction is provided greatly.
