Abstract
The utility model provides an auger stem. The auger stem comprises a stem body, a male connector and a female connector, wherein the male connector and the female connector are arranged at the two ends of the stem body. The female connector is provided with internal threads and external threads. A multi-head spiral band is wound around the stem body. An alloy block is arranged on the spiral band in a scarfweld mode. The internal threads and the outer threads are trapezoid taper threads. The auger stem is simple in structure; due to the arrangement of the spiral band, the chip removal speed is high, the advancing efficiency is high, the service life is prolonged, and the phenomena of hole collapse, jamming of a drilling tool and loss of the drilling tool can be effectively reduced; due to the alloy block arranged on the spiral band, the strength of the spiral band can be improved, and the service life of the auger stem is further prolonged; the connectors are provided with British-system trapezoid taper threads, so that detachment is more convenient.
Description
Technical field
The utility model relate to a kind of in coal seam, be used for boring instrument, particularly a kind of auger stem.
Background technology
In engineering geological drilling and mineral reserve drilling process, drilling rod was generally column type drilling rod in the past, column type drilling rod is in row's Rock Powder, to rely on the cooling water of drill bit place ejection that Rock Powder is taken out of from boring, because the complexity of drilling depth and geologic structure changes, when partial collapse appears in hole inwall because geologic structure is soft, make a large amount of rocks and earth encase drilling rod, Rock Powder is piled up, blocked in boring, powder can not be quickly discharged, cause the brill accident of embracing, auger stem has been born for this reason, but, the auger stem using is at present mainly that single head helical blade is set on the body of rod, this drilling rod chip removal speed is slower, efficiency is low, in use find that helical blade easily damages, excavation cost is higher, in addition, two end joints mainly adopt regular screw threads to connect, it is also convenient not to use.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides that a kind of cost is low, the auger stem of long service life.
To achieve these goals, the utility model provides following technical scheme: a kind of auger stem, comprise the male and female joint at the body of rod and two ends thereof, on described male and female joint with internal and external screw thread, on the described body of rod, be wound around multi-head spiral band, described internal and external screw thread is taper thread.
As preferably, scarfweld alloy block on described hurricane band.
Can find out by above technical scheme, the utility model is simple in structure, the setting of hurricane band makes its chip removal speed fast, drivage efficiency is high, increases the service life, and can effectively reduce collapse hole, bit freezing and lose brill phenomenon, the alloy block arranging on hurricane band can make hurricane band self intensity enhancing, in the application life that further extends drilling rod, joint adopts trapezoidal taper thread made in Great Britain, makes to remove convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: the 1-body of rod, 2-hurricane band, 3-alloy block.
The specific embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of auger stem as shown in Figure 1, comprise the male and female joint at the body of rod 1 and two ends thereof, on described male and female joint with internal and external screw thread, on the described body of rod 1, be wound around multi-head spiral band 1, make drilling rod chip removal speed fast, drivage efficiency is high, increase the service life, and can effectively reduce collapse hole, bit freezing and lose brill phenomenon, scarfweld alloy block 3 on described hurricane band 2, makes hurricane band self intensity enhancing, thereby extends the application life of drilling rod, described internal and external screw thread is trapezoidal taper thread made in Great Britain, makes to remove convenient.
In accompanying drawing 1, internal and external screw thread does not all draw.
The technical scheme above the utility model embodiment being provided is described in detail, applied principle and the embodiment of specific case to the utility model embodiment herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in the specific embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
Claims (2)
1. an auger stem, comprises and on described male and female joint, with internal and external screw thread, it is characterized in that the male and female joint at the body of rod and two ends thereof: on the described body of rod, be wound around multi-head spiral band, described internal and external screw thread is taper thread.
2. auger stem according to claim 1, is characterized in that: scarfweld alloy block on described hurricane band.
