Abstract
The utility model discloses a heterotype drill rod which belongs to a tool for rock drilling, and the heterotype drill rod comprises a bit shank and a rod body. The central parts of the bit shank and the rod body are provided with cooling through holes, and the bit shank and the rod body are in the split type structure. The front end of the rod body is provided with rods and cones, and the back end of the rod body is provided with a connecting body. The front end of the bit shank is provided with a shank collar, and a connecting trough which is coordinated with the connecting body is arranged in the shank collar. The back end of the bit shank is provided with a shank, and compared with the prior art, the heterotype drill rod has the advantages of reasonable design, simple structure, easy processing, convenient use, low cost and long service life, etc.
Description
Technical field
The utility model relates to a kind of rock drilling instrument, specifically a kind of special-shaped drill steel.
Background technology
At present, be used for drilling tool that rock drilling uses and all be disposable forging forming, the shank collar with lugs and body of rod one is arranged on the outer of lugs and body of rod diacritical point, drilling tool is fixed on the hammer drill by shank collar.Because shank collar forges and presses out from the lugs and the body of rod, this makes near the metal structure the shank collar be out of shape, and in use, near the metal material the shank collar is easy to fracture, has so not only increased construction cost, and has reduced operating efficiency.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provide a kind of easy to use, cost is low, a kind of special-shaped drill steel of long service life.
The technical scheme that its technical problem that solves the utility model adopts is: this drilling tool comprises the lugs and the body of rod, the centre of the lugs and the body of rod is provided with the cooling through hole, the lugs and the body of rod are for dividing body structure, the front end of the body of rod is provided with the bar awl, the rear end of the body of rod is provided with connector, the front end of lugs is a shank collar, has the link slot that matches with connector in the shank collar, and the rear end of lugs is a bit shank.
Described connector is the taper connection body, and link slot is the taper connection groove, connector and link slot clamping.
Described connector and link slot are by being threaded.
Described connector and link slot welding.
A kind of special-shaped drill steel of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, easy to use, characteristics such as cost is low, long service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the syndeton schematic diagram of kind of special-shaped drill steel.
Accompanying drawing 2 is the another kind of syndeton schematic diagram of kind of special-shaped drill steel.
Among the figure: 1, bar awl, 2, the body of rod, 3, connector, 4, shank collar, 5, link slot, 6, the cooling through hole, 7, bit shank, 8, lugs.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of special-shaped drill steel of the present utility model, its structure comprises the lugs 8 and the body of rod 2, the centre of the lugs 8 and the body of rod 2 is provided with cooling through hole 6, the lugs 8 and the body of rod 2 are for dividing body structure, the front end of the body of rod 2 is provided with bar awl 1, and the rear end of the body of rod 2 is provided with connector 3, and the front end of lugs 8 is a shank collar 4, have the link slot 5 that matches with connector 3 in the shank collar 4, the rear end of lugs 8 is a bit shank 7.Between connector 3 and the link slot 5 or the taper clamping, perhaps be threaded, perhaps welding.
A kind of its processing and fabricating of special-shaped drill steel of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of manual, be the known technology of those skilled in the art.
