Abstract
The utility model discloses a kind of automatic-switching type hydraulic flushing in hole ejector, it is characterized in that: comprise main body, nozzle and be arranged on spring, rubber washer, steel ball, the baffle ring in main body; In described main body, be hollow bore, front end is external screw thread connecting rod, and end is internal thread connector, and inwall is carved with the spray orifice communicating with outer wall nozzle.The utility model is threaded connection between drill bit and drilling rod, utilizes hydraulic pressure control steel ball and rubber washer closure or separates, and realizes automatic switchover exhalant canal, simple in structure, easy to process, cheap, practical, long service life.
Description
Technical field
The utility model relates to coal mine gas extraction drill hole apparatus field, relates in particular to a kind of automatic-switching type hydraulic flushing in hole ejector.
Background technology
Country is considered as Life Engineering and resource engineering gas pumping engineering, its hydraulic flushing technology is to improve gas pumping efficiency, one of control Gas Disaster, the important measures that realize comprehensive gas utilization, it is taking rock pillar or coal column as safety curtain, to coal seam internal drilling, utilize water under high pressure to wash away coal body, excite spray orifice, discharge broken coal and gas, discharge outstanding potential to reduce and elimination outburst hazard.At present, widely used hydraulic flushing in hole way is to use target drill to beat behind finishing drilling hole, exit drilling rod and change punching ejector, continue into drilling rod, use again water under high pressure punching, this way of moving back drilling rod replacing ejector not only expends man-hour, causes the inadequate problem of the degree of depth but also exist continuous bar direction skew to cause the hole plug that collapses.
Domestic published patent documentation CN103485721A, CN103291219A have announced respectively a kind of piston type high-low pressure hydraulic flushing in hole converter and brill rushes bit Integrated, but there is following defect: 1. structure is comparatively complicated, difficulty of processing is larger, and cost is higher; 2. piston and shell body close contact are subject to water quality impact larger, and on-the-spot utilization exists some problems; 3. bore that to rush one influenced larger, injure all.For this reason, need to improve.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of automatic-switching type hydraulic flushing in hole ejector of simple in structure, easy to process, practical, long service life is provided.
A kind of automatic-switching type hydraulic flushing in hole ejector, is characterized in that: comprise main body, nozzle and be arranged on spring, rubber washer, steel ball, the baffle ring in main body; In described main body, be hollow bore, front end is external screw thread connecting rod, and end is internal thread connector, and inwall is carved with the spray orifice communicating with outer wall nozzle.
Further, described through hole middle part is carved with the chamber that four diameters differ and connect successively, mounting spring, rubber washer, steel ball, baffle ring respectively, its internal diameter rubber washer chamber is greater than steel ball chamber and is greater than spring cavity and is greater than external screw thread connecting rod internal diameter, and steel ball size is slightly less than steel ball chamber diameter and internal thread connector internal diameter.
Further, described baffle ring is hollow convex round platform, and welding or screw thread are fixed in baffle ring chamber, steel ball below, and its outer diameter equals steel ball size.
The utility model beneficial effect is compared with prior art: automatic-switching type hydraulic flushing in hole ejector can be connected to form one by screw thread and drill bit, drilling rod, utilize hydraulic pressure control steel ball and rubber washer closure or separate, realize automatic switchover exhalant canal, need not change back and forth, and simple in structure, easy to loading and unloading, cheap, practical, adopt that steel ball closed manners sensitivity is strong, easy to process, long service life simultaneously.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, main body, 2, nozzle, 3, spring, 4, rubber washer, 5, steel ball, 6, baffle ring, 7, through hole, 8, external screw thread connecting rod, 9, internal thread connector, 10, spray orifice.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, but therefore the utility model is not limited among described scope of embodiments.
Participate in a kind of automatic-switching type hydraulic flushing in hole ejector shown in Fig. 1, comprise main body 1, nozzle 2 and be arranged on spring 3, rubber washer 4, steel ball 5, the baffle ring 6 in main body 1; In described main body 1, be hollow bore 7, front end is external screw thread connecting rod 8, and end is internal thread connector 9, and inwall is carved with the spray orifice 10 communicating with outer wall nozzle 2.
Further, described through hole 7 middle parts are carved with the chamber that four diameters differ and connect successively, mounting spring 3, rubber washer 4, steel ball 5, baffle ring 6 respectively, its internal diameter rubber washer 4 chambeies are greater than steel ball 5 chambeies and are greater than spring 3 chambeies and are greater than external screw thread connecting rod 8 internal diameters, and steel ball 5 diameters are slightly less than steel ball 5 chamber diameters and internal thread connector 9 internal diameters.
Further, described baffle ring 6 is hollow convex round platform, and welding or screw thread are fixed in steel ball 5 baffle ring chambeies, below, and its outer diameter equals steel ball size.
When use, automatic-switching type hydraulic flushing in hole ejector front end external screw thread connecting rod 8 connects drill bit, end internal thread connector 9 jointed rods; In the time that needs creep into, inject low-pressure water, spring 3 is in natural relaxed state, and steel ball 5 separates with rubber washer 4, and low-pressure water enters drill bit by external screw thread connecting rod 8 and carries out cooling; In the time of needs hydraulic flushing in hole, inject water under high pressure, hydraulic pressure impacts steel ball 5 Compress Springs 3, steel ball 5 and rubber washer 4 closures, water under high pressure sprays by spray orifice 10 and nozzle 2.
Although described by reference to the accompanying drawings above embodiment of the present utility model, but those of ordinary skill in the art also can recognize making various variations or amendment in the scope of claims, these modifications and variations are interpreted as within scope of the present utility model and intention.
