Side, sliding block are placed on connecting rod outer wall, and in sliding slot, and the connecting rod is hollow structure, the connecting rod other end
On open there are two venthole, and respectively be connected inside connecting rod, be provided with annular groove on the outside of the connecting rod other end, and point
It is not connected with two ventholes, filter screen is placed in the annular groove of the connecting rod other end, and drill bit is placed on the connecting rod other end,
Two rotating bars ride on drill bit respectively, and symmetrical, and described rotating bar one end is hinged by fixed pin and drill bit, the brill
Bar-shaped trough there are two being opened on head, and it is corresponding with two rotating bars respectively, fixed spring is placed in bar-shaped trough, the fixed spring
One end is connected with adjacent rotating bar, and the other end is connected with drill bit.
In use, when carrying out extraction borehole to coal mine gas, external drilling machine is connected with connector sleeve first, outside is bored
Machine drives drilling rod to rotate, and drilling rod drives sliding slot rotation, sliding slot and sliding block relative movement, since sliding slot is arcuate structure, and highly
It continuously decreases from one end to the other side, when sliding slot one end is moved to slide position, drill bit and the drilling rod other end are in contact, filtering
Net is incorporated into drilling rod, and drilling rod drives connecting rod to rotate by sliding block, and connecting rod drives drill bit rotation, and then drill bit is to coal
Layer drills, and after drill bit is drilled into designated position, external drilling machine, which stops boring, to be moved, and external drilling machine is removed from drilling rod, then
External extraction pipeline is connected with connector sleeve, using die nut convolution connector sleeve, two rotating bars are respectively in fixed spring
It is stuck in drilling under promotion, and then makes drill chuck in drilling, connector sleeve drives drilling rod convolution, drilling rod that sliding slot is driven reversely to turn
Dynamic, sliding slot is moved backward along sliding block, and when the sliding slot other end is moved to slide position, the connecting rod other end is stretched out of drilling rod
Go out, filter screen leakage cruelly drills interior methane gas after filter screen filtration, connecting rod is entered by two ventholes in drilling
It is interior, then into drilling, finally flowing into external extraction pipeline, realize gas pumping, reach and used on coal mine, watt
The purpose to drill when this extraction.
Advantageous effect.
One, simple in structure, it is convenient and practical.
Two, cheap, it is easy to spread.
Three, the interior gas overflowing that drills can be prevented, coal mine gas drainage safety is improved.
