Abstract

The utility model belongs to the field of underground pneumatic jumbolter equipment in a coal mine, and particularly relates to a mining water drill. A connecting seat is fixed at the center of a base by welding, two ends of the connecting seat are provided with counter bores and connectors which are communicated with each other, the two ends of the connecting seat are respectively provided with an outer drill bushing and an inner drill bushing through the connectors, a water drill bushing is arranged on the base and provided with a limiting mechanism and a positioning drill stem, the end of the positioning drill stem is fixedly connected with a water drill bit, the positioning drill stem is connected in the connecting seat through the inner drill bushing, and penetrates through the limiting mechanism, and the drill stem is connected in the connecting seat through the outer drill bushing. The mining water drill has the advantages of simple structure, reasonable design, good molding of a needling of a drilled wooden pillar, high efficiency, safety and reliability, and is suitable for being used for installing various underground pneumatic jumbolters in the coal mine.

Description

Mining water bores
Technical field
The utility model belongs to pneumatic jumbolter apparatus field under the coal mine, and especially a kind of mining water bores.
Background technology
At present, under coal mine, during getting working face fixed schedule winch, all to cut a hole 6 pin needlings of system " four press two in an opposite direction ".When cutter was made the pin needling in the past, the employing explosive that has collapsed, and not only causes gas explosion easily, and the needling moulding of collapsing out is bad, and pin is fixing insecure; System is manually cut a hole in the employing that has, and both wastes time and energy, and operating efficiency is also low.
Summary of the invention
The purpose of this utility model is the weak point that exists in the above-mentioned technology, provides a kind of mining water to bore, and it can be applied to jumbolter and can produce good effect under coal mine.
The technical scheme that realizes the utility model purpose is as follows:
Mining water bores, it comprises base, and the base center is welded with Connection Block, and these Connection Block two ends are provided with counterbore and connector, counterbore is communicated with connector, the Connection Block two ends are respectively equipped with outer drill bushing and interior drill bushing by connector, and base is provided with the water drill bushing, and the water drill bushing is provided with position-limit mechanism and location drilling rod, the spitting drill boom end is fixedly connected with the water drill bit, the location drilling rod is connected in the Connection Block by interior drill bushing, and the location drilling rod passes position-limit mechanism, and drilling rod is connected in the Connection Block by outer drill bushing.
Described position-limit mechanism comprises stop collar and spring, and stop collar is located in the water drill bushing, and spring is located between stop collar and the base.
Described connector and outer drill bushing, interior drill bushing are by being threaded.
Adopted such scheme, the utility model is connected with jumbolter by drilling rod, and benefit of the present utility model is simple in structure, reasonable in design, not only bore the pin needling forming of making, efficient height, and safe and reliable, pneumatic jumbolter installs and uses under the suitable all kinds of coal mine.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of Connection Block.
The specific embodiment
As Fig. 1, shown in Figure 2, mining water bores, it comprises base 4, base 4 centers are welded with Connection Block 3, these Connection Block 3 two ends are provided with counterbore 32 and connector 31, counterbore 32 is communicated with connector 31, Connection Block 3 two ends are by connector 31 be threaded respectively outer drill bushing 2 and interior drill bushing 6, base 4 is provided with water drill bushing 5, water drill bushing 5 is provided with position-limit mechanism and location drilling rod 9, drilling rod 9 ends, location are fixedly connected with water drill bit 10, and location drilling rod 9 is connected in the Connection Block 3 by interior drill bushing 6, and location drilling rod 9 passes position-limit mechanism, drilling rod 1 is connected in the Connection Block 3 by outer drill bushing 2, position-limit mechanism comprises stop collar 7 and spring 8, and stop collar 7 is located in the water drill bushing 5, and spring 8 is located between stop collar 7 and the base 4.
