Abstract
A kind of spy coal borer bar, comprise the body of rod, the periphery uniform winding of the body of rod has spiral channel, it is characterized in that: the front intersegmental part of the described body of rod is provided with limited bayonet a; The rear of external square toes is arranged in limited bayonet a, is connected with the body of rod by limited bayonet a; The upper surface of described external square toes front end is provided with spacing preiection, and the below of spacing preiection is pressure hole, and pressure is provided with stage clip in hole, and spacing preiection is arranged on stage clip; The rear inside of the described body of rod is provided with limited bayonet b; The upper surface of limited bayonet b is provided with stopper slot, and stopper slot is for being obliquely installed.As preferably, the spacing of spiral channel is 25cm ~ 115cm.The usefulness of this utility model is, in this utility model adopts, four directions, outer four directions coordinate location, good positioning effect, in use procedure, the body of rod is stablized, and this utility model row powder is effective, drilling efficiency is high, reduce the generation of embracing the phenomenons such as brill, bit freezing, extend the application life of drilling rod, improve operating efficiency.
Description
Technical field
The utility model belongs to engineering drilling, mine locating drilling tool accessory field, coal seam, is specifically related to a kind of spy coal borer bar.
Background technology
In mine locating drilling tool, drilling rod is absolutely necessary one of apparatus, and when carrying out mine coal seam, can the work that can drilling rod normal, safe be one of the key that normally carry out of drilling project.When drilling rod uses, need to carry out dismounting according to the coal seam degree of depth, current drilling rod majority uses external connector or inside and outside silk to connect, and this connecting mode easily occurs that stripped thread ruptures in use, also needs rear installation to be aimed in inside and outside silk road, operation inconvenience during connection.
Summary of the invention
For above-mentioned deficiency, the utility model provides a kind of simple and practical, easy to operate, effective spy coal borer bar of row's powder.
The utility model is achieved through the following technical solutions: a kind of spy coal borer bar, and comprise the body of rod, the periphery uniform winding of the body of rod has spiral channel, it is characterized in that: the front intersegmental part of the described body of rod is provided with limited bayonet a; The rear of external square toes is arranged in limited bayonet a, is connected with the body of rod by limited bayonet a; The upper surface of described external square toes front end is provided with spacing preiection, and the below of spacing preiection is pressure hole, and pressure is provided with stage clip in hole, and spacing preiection is arranged on stage clip; The rear inside of the described body of rod is provided with limited bayonet b; The upper surface of limited bayonet b is provided with stopper slot, and stopper slot is for being obliquely installed.
As preferably, the spacing of spiral channel is 25cm ~ 115cm.
The usefulness of this utility model is, in this utility model adopts, four directions, outer four directions coordinate location, good positioning effect, in use procedure, the body of rod is stablized, and this utility model row powder is effective, drilling efficiency is high, reduce the generation of embracing the phenomenons such as brill, bit freezing, extend the application life of drilling rod, improve operating efficiency.

Detailed description of the invention
A kind of spy coal borer bar, comprise the body of rod 1, the periphery uniform winding of the body of rod 1 has spiral channel 2, it is characterized in that: the front intersegmental part of the described body of rod 1 is provided with limited bayonet a3; The rear of external square toes 4 is arranged in limited bayonet a3, is connected with the body of rod 1 by limited bayonet a3; The upper surface of described external square toes 4 front end is provided with spacing preiection 5, and the below of spacing preiection 5 is pressure hole, and pressure is provided with stage clip 6 in hole, and spacing preiection 5 is arranged on stage clip 6; The rear inside of the described body of rod 1 is provided with limited bayonet b7; The upper surface of limited bayonet b7 is provided with stopper slot 8, and stopper slot 8 is for being obliquely installed.
In the present embodiment, the front intersegmental part of the body of rod 1 is provided with limited bayonet a3, external square toes 4 are connected with the body of rod 1 by limited bayonet a3, its rear is arranged in limited bayonet a3, the rear inside of the body of rod 1 is provided with limited bayonet b7, the upper surface of limited bayonet b7 is provided with the stopper slot 8 of inclination, and the incline direction of stopper slot 8 is inwardly surface thereof, and it act as with the spacing preiection 5 set by external square toes 4 upper surface mutually spacing.When needs are assembled, external square toes 4 front end is inserted in the limited bayonet b7 set by rear of the body of rod 1, spacing preiection 5 on external square toes 4 is mutually spacing with stopper slot 8, and the below of spacing preiection 5 is stage clip 6, can with the height of the angle of inclination adjustment spacing preiection 5 of stopper slot 8.This utility model is easy to assembly, and during use, body of rod stability is high, convenient operation.As preferably, the spacing of spiral channel 2 is 25cm ~ 115cm.In the present embodiment, the spacing of spiral channel is 72cm, and through result of use, the spiral channel row powder of this spacing is effective, drilling efficiency is high.
