Abstract
The utility model relates to a tool for drilling in a coal seam, in particular to a spiral drill pipe. The spiral drill pipe comprises a drill pipe body and spiral blades which are integrated on the outer wall of the drill pipe body in a spiral shape; and the spiral blades are multi-head spiral blades with consistent spiral directions and equal pitch, and integrally continue from one end to the other end of the drill pipe body in the spiral shape. The spiral drill pipe has the advantages of high chip and slag removal rate, high tunneling efficiency, can effectively prevent and reduce hole collapsing, drill sticking and drill losing and prolong the service life of the drill pipe so as to effectively reduce the tunneling cost, and is quite an ideal spiral drill pipe for drilling in the coal seam.
Description
Technical field
The utility model relates to a kind of instrument that boring is used in the coal seam, particularly a kind of auger stem.
Background technology
In the Coal Production process, in order to prevent coal and gas burst accident and water leak accident, before driving, need in the coal seam, beat release aperture the gas in the coal seam is discharged to eliminate coal seam stress, perhaps verified no water layer by boring.At present the helical blade that connects on the used auger stem of punching on the colliery is the single head helical blade, and this drilling rod chip removal speed is slower, influences the driving progress, and efficient is low, and in addition, the drilling rod loss is fast, and excavation cost is higher.
The utility model content
Technical problem to be solved in the utility model provides and a kind of helical blade on the auger stem is designed to the multi-head spiral blade that the consistent and pitch of the hand of spiral equates, in order to overcome the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: auger stem, comprise that drilling rod body and curl are combined in the helical blade on the drilling rod body outer wall, described helical blade is the multi-head spiral blade that the hand of spiral is consistent and pitch equates, is extended to the other end of drilling rod body on the whole from an end of drilling rod body with helical form.
Described helical blade is the twin-feed spiral blade.
The obtained technique effect of the utility model is: chip removal, deslagging speed are fast, the drivage efficiency height can effectively be avoided and minimizing collapse hole, bit freezing and lose the brill phenomenon, prolongs drilling life of drill pipe, thereby effectively reducing excavation cost, is the auger stem that a kind of comparatively desirable coal bed drilling uses.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Below with reference to drawings and Examples the utility model is further described: as shown in the figure, auger stem, comprise that drilling rod body 1 and curl are welded on the helical blade 2 on drilling rod body 1 outer wall, described helical blade 2 is the twin-feed spiral blade that the hand of spiral is consistent and pitch equates, is extended to the other end of drilling rod body 1 on the whole from an end of drilling rod body 1 with helical form.
But foregoing description only proposes as a kind of technical application scheme of the present utility model, not as the single restrictive condition to its structure.
Claims (2)
1. auger stem, comprise that drilling rod body (1) and curl are combined in the helical blade (2) on drilling rod body (1) outer wall, it is characterized in that the multi-head spiral blade that described helical blade (2) is consistent for the hand of spiral and pitch equates, be extended to the other end of drilling rod body (1) on the whole with helical form from an end of drilling rod body (1).
2. auger stem according to claim 1 is characterized in that described helical blade (2) is the twin-feed spiral blade.
