Description
Technical field
The utility model belongs to field of coal mining, specifically is exactly the protrusion-dispelling drilling rod of usefulness of drawing out methane.
Background technology
The protrusion-dispelling drilling rod, in the coal seam, hole exactly, extract gas out by boring then, effectively to utilize gas, and prevent the drilling rod of gas disaster, existing drilling rod nearly all is air inlet or water inlet from drilling rod, from giving vent to anger between drilling rod and the hole wall or taking coal dust out of water outlet the time, such working method is easy to occur the hole of collapsing behind soft seam, can not effectively creep into, so the degree of depth of boring is little, the disclosed patent No. of Chinese patent is 201020190784.6 utility model patent, though be to give vent to anger in bar, but its venthole connecting portion blow-by, still the hole phenomenon of collapsing can occur, moreover its air inlet port must be arranged on the central axis of drilling rod, limit the position of air inlet port, occurred importing and exporting fortune fortune water imbalance easily.
Summary of the invention
The purpose of this utility model solves exactly in the past that the protrusion-dispelling drilling rod can not effectively creep into, though the problem of perhaps giving vent to anger in the bar and sealing bad, unbalance in foreign trade and being unfavorable for coal dust by auger stem.
The utility model comprises the drilling rod body, and the drilling rod body is provided with two axially extending bores at least.
Corresponding through hole sealing is communicated with between the utility model drilling rod.It is the junction sealing that i.e. sealing is communicated with.
Through hole of axially extending bore of the present utility model is arranged on the drilling rod center and constitutes centre bore, and other through hole is around around centre bore shape trend in the shape of a spiral.
Be that pipe collar connects between the utility model drilling rod.
The utility model pipe collar one end is stuck on the drilling rod, and the pipe collar other end is threaded on the drilling rod.
Between the utility model drilling rod alignment pin is set.
Alignment pin of the present utility model refers to the drilling rod junction, on one side through hole place projecting tube as alignment pin, the dowel hole that cooperates with projecting tube is set on the another side through hole.
The number of axially extending bore of the present utility model is one of two to six.
Advantage of the present utility model is good airproof performance, during use, advance as gas or water by one or two or three air inlets or water inlet, discharge gas or water by one or two or three exhausts or outfall again, when discharging gas or water, take the coal dust in bar out of, just can not destroy hole wall, solve the collapse problem in hole of soft seam, especially when boring, turn round enter soft seam after, use this patent hole of can more effective solution collapsing.Establishing under the situation of centre bore, centre bore is during as the air inlet inlet opening, and the exhaust outlet hole is done in other hole, and when centre bore was done the exhaust outlet hole, the air inlet inlet opening was done in other hole.Because steam vent moves towards around the helical form that centre bore is rifling, during the drilling rod rotation, help the discharge of water or gas, also help the discharge of coal dust simultaneously.
