Abstract
The utility model relates to a diamond composite piece drilling bit for boring a hole, which belongs to a drilling boring guide diamond composite piece drilling bit under a coal mine well. The utility model is characterized in that the excircle positions of a drilling bit body are welded a plurality of cylinder alloys, two circles of alloy supporting pole holes are drilled on the bottom surface of junction of the drilling bit body and a guide head, the outer circle is provided with six holes, the inner circle is provided with three holes, diamond composite pieces are welded on alloy supporting poles, the alloy supporting poles are arranged in the alloy supporting pole holes of the drilling bit body, and a plurality of water grooves and a plurality of water outlet holes are arranged on the drilling bit body. The utility model has the advantages of simple structure, convenient operation, quick drilling speed, high efficiency, low cost, no deflection on the boring hole and long service life for the drilling bit. The utility model can be widely used for boring the hole under the well. A hole of a big diameter is drilled by a small drilling machine.
Description
The utility model reaming guiding diamond compact bit belongs to colliery down hole drill reaming guiding diamond composite drill bit.
The available technology adopting small-sized drill, the alloy bit diameter is little, can not bore macropore, and rate of penetration is slow, and efficient is low, and labour intensity is big, and drilling life of bit is short, easily causes the probing inclined hole, makes boring not reach designing requirement, and inclined hole is scrapped, and the cost height is difficult for applying.
The purpose of the utility model reaming guiding diamond compact bit, be to overcome above-mentioned defective and design a kind of reaming guiding diamond compact bit, it is that composite sheet is welded on the alloy pillar, be welded on the bit body by the alloy pillar, guide head is set on the drill bit prevents hole scattering, carrying out classification by bearizing mechanism creeps into, diamond compact cuts, cutting drilling efficiency height, long service life, the counterboring hole is deflection not, labour intensity is low, time saving and energy saving, cost is low, is widely used on the counterboring hole, down-hole.
The utility model reaming guiding diamond compact bit takes following technical scheme to realize, it is by guide head and diamond compact and alloy pillar are set on the bit body, bit body cylindrical place welding cylindrical alloy, be drilled with two circle alloy pillar holes on bit body and the guide head intersection bottom surface, the outer ring is provided with six holes, inner ring is provided with three holes, diamond compact is welded on the alloy pillar, the alloy pillar is welded in the alloy pillar hole of bit body, tank and weep hole are set on the bit body, tank and weep hole play cooling and row's rock dust, and guide head is set upright guiding with reaming bit and prevented hole scattering, and the alloy pillar is embedded on the bit body.
The effect of the utility model reaming guiding diamond compact bit is simple in structure, and easy to operate, the reaming rate of penetration is fast, gets out large diameter hole with drilling-in unit, the efficient height, cost is low, and the counterboring hole is deflection not, drilling life of bit is long, and is time saving and energy saving, is widely used on the counterboring hole, down-hole.
The utility model reaming guiding diamond compact bit will describe in further detail in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model reaming guiding diamond compact bit.
Fig. 2 is the lateral view of the utility model reaming guiding diamond compact bit.
Fig. 3 is the alloy pier construction schematic diagram of the utility model reaming guiding diamond compact bit.
