Abstract
The utility model relates to a shallow hole drilling tool is applicable to the colliery and discharges drilling, fabrication hole, coal seam water injection hole, blasting coal breakage hole in the pit, also can be used to other trades and use the engineering hole of compressed air as the power supply. The hand-held pneumatic coal drill comprises an air inlet valve assembly, a pneumatic motor, an exhaust valve assembly, a transmission part and the like. The hand-held rotary silencer is characterized in that the hand-held rotary silencer is arranged in the handle with the silencing sleeve, and the silencing effect is good. Compact structure, high strength, safe and reliable operation and convenient use.
Description
The utility model is a kind of shallow bore hole drilling tool, is applicable to coal mine gas bleeder off hole, fabrication hole, coal-bed flooding hole, explosion coal-falling hole, also can be used for other industry and uses the hole to press the be used as power engineering in source of wind.
Containing gaseous mine, particularly containing high gas projecting mine, be the disaster that prevention gas brings, people are constantly seeking new approach, except that studying on technology; On the equipment that prevention gas is given prominence to, develop towards efficient, small-sized, multiple power source, the full-automatic direction of far distance controlled.At present, Japan adopts pneumatic drilling machine, but volume is bigger.West Germany uses hand-held wind coal borer, though this rig volume is little, easy for operation, does not have silencing means, and noise intensity reaches 95～100 decibels, the infringement workman sense of hearing.The domestic MZ-12 type electricity coal borer that still adopts the sixties, EZ
2-20 electric rock drills all are used as power with power supply, because the underground work humid environment makes the shell of electric coal borer often lead shell, grounding phenomenon, especially the outstanding mine of coal and gas are being arranged, and threaten bigger to the safety in production of mine and miner's life security.
The purpose of this utility model is in order to satisfy the needs of China's coal-mine production development, especially be the punching of coal road driving in that the outstanding mine of gas is arranged, it is safe, the light hand-held wind coal borer of power to press wind that drawing-off gas boring, face firing coal falling hole, fabrication hole etc. provide a kind of.

Structure of the present utility model and operating principle
Hand-held wind coal borer (Fig. 1) is made up of inlet valve complement 1, air motor 2, exhaust valve complement 3, driving section 4.
Inlet valve complement (Fig. 2) is made up of inlet suction port body 5, tuyere joint 6, spool 7, control air quantity handgrip 8.Control air quantity handgrip 8 can rotate (0 °～115 °), and effect is the registration of regulating spool 7 and position, tuyere joint 6 hole; Can also regulate the size and the switch air motor of air inflow.To reach rotating speed and the output torque of regulating air motor.The thread size of tuyere joint is the standard size of down-hole pressure ventilation pipe joint, connects easy to use.
Air motor (Fig. 3) is made up of a pair of intermeshing external gear 9, bearing 10, housing 11.
The shell structure of this hand-held wind coal borer air motor is whole case type.A pair of external gear pump (Z=9 m=5) 9 is contained in the housing, and the bearing of gear (42204) is contained in the both sides in the housing respectively, and its end play is adjusted by the sealing mat between end cap and housing.The gear assembly structure of air motor adopts the advantage of whole case type: simple in structure, compact, when running steadily, mesh, safe and reliable.
Fig. 4 is an external toothing birotor air motor schematic diagram.This motor is a positive displacement motor.Gear 12,13, housing 14, air inlet pipe 15, the contact point of 16, two gears of stack and inner walls is respectively A
1, A
2When compressed air entered air cavity, compressed air to do work made air motor produce turning moment.
Exhaust valve complement (Fig. 5) is made of steam vent joint 17, noise damper 18, noise reduction cover handgrip 19.The volume of noise damper 18 is little, can directly be contained in the handgrip 19 of band noise reduction cover, and compact conformation, good muffling effect, noise can be reduced to 85 decibels.
Driving section (Fig. 6) is made of internal gear 20, main shaft 21, bearing 22, shell 23, coupling sleeve 24.Internal gear (Z=53 m=1.5) is exported turning moment with air motor with going out of air motor after the engagement one-level is slowed down in the shaft gear (Z=10 m=1.5) and is passed to drilling rod through main shaft.Coupling sleeve 24 adopts two kinds of forms, can directly exchange on main frame.A kind ofly can directly connect the transmission twist drill rods; Another kind of band water pigtail, transmission hollow drill pipe, but wet type punching, or be used for gas, dust sampling.
Advantage of the present utility model:
The characteristics of this hand-held wind coal borer are hand-held rotary, and noise damper is contained in the handgrip of band noise reduction cover, good muffling effect.Compact conformation, the intensity height, safe and reliable, easy to use.
