Abstract
The utility model discloses a novel drill rod. The novel drill rod comprises a drill rod body, a drill rod core hole and a drill rod core rod and is characterized in that the surface, which is in contact with the drill rod core hole, of the tail of the drill rod core rod is arranged as a curved surface, the top of the drill rod core rod is arranged as a cone, the contact surface is arranged as the conical surface, an air guide groove is formed in a combined part of the drill rod core rod and the drill rod core hole, the diameter of the drill rod core hole is 60mm-120mm, and the length of the drill rod core hole is 350mm-700mm. The service life of the novel drill rod adopting the structure is greatly prolonged, and the working efficiency of the novel drill rod is greatly improved.
Description
Technical field
The utility model relates to engineering tools, particularly a kind of Novel drill rod.
Background technology
In Current Engineering Construction, advanced quartering hammer has progressively replaced drilling and blasting in the past, but the drill steel of quartering hammer is because design is unreasonable at present, cause loss quite serious, and operating efficiency is low, the drill steel that the annual whole nation consumes according to the preliminary statistics has more than 10 ten thousand, ample resources and construction cost undoubtedly, are wasted, if the patent No. is a kind of crushing hammar drill rod as described in 201220358606.9, though it has solved the not saturating shortcoming of prior art quenching, but it is in structural design, some problems in the connection of each position and size are never resolved, cause operating efficiency and loss still quite serious.
Utility model content
The problem existing for prior art, it is high that the utility model aims to provide a kind of operating efficiency, a kind of Novel drill rod of long service life.
The utility model provides a kind of Novel drill rod, comprises drill steel body, drill steel core hole, and drill steel plug, is characterized in that, and described drill steel plug afterbody and described drill steel core hole contact-making surface are curved surface setting, and described drill steel plug top is set to cone.
Preferably, described contact-making surface is conical surface setting.
Preferably, the described drill steel plug position that combines with described drill steel core hole has air guide groove.
Preferably, described drill steel core bore dia is 60mm ~ 120mm, and length is 350mm ~ 700mm.
Further, described conical surface angle is less than 180 degree.
Compared with prior art, described drill steel plug afterbody and described drill steel core hole contact-making surface adopt conical surface setting to the described Novel drill rod that the utility model provides, and drill steel plug top is set to cone, effectively raises operating efficiency; On described drill steel plug and detailed annotation position, described drill steel core hole, air guide groove is set, has solved prior art because existing air cannot contact the problem putting in place in drill steel core hole, ensured the quality of drill steel, improved physical life.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of Novel drill rod that the utility model proposes;
Fig. 2 is the expanded view of the drill steel plug of the utility model Fig. 1
drawing reference numeral explanation
1-drill steel body, 2-drill steel core hole, 3-drill steel plug, 4-air guide groove.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention:
Please refer to Fig. 1, for the structural representation of the utility model embodiment, in the present embodiment, described a kind of Novel drill rod, comprise drill steel body 1, drill steel core hole 2, drill steel plug 3, described drill steel plug 3 afterbodys and described drill steel core hole 2 contact-making surfaces are conical surface setting, and described conical surface angle is less than 180 degree, and described drill steel core hole 2 optimum diameters are 60mm ~ 120mm, optimum length is 350mm ~ 700mm, please refer to Fig. 2, described drill steel plug 3 tops are set to cone, and described drill steel plug 3 position that combines with described drill steel core hole 2 has air guide groove.
Compared with prior art, described drill steel plug afterbody and described drill steel core hole contact-making surface adopt conical surface setting to the described Novel drill rod that the utility model provides, and drill steel plug top is set to cone, effectively raises operating efficiency; On described drill steel plug and detailed annotation position, described drill steel core hole, air guide groove is set, has solved prior art because existing air cannot contact the problem putting in place in drill steel core hole, ensured the quality of drill steel, improved physical life.
By reference to the accompanying drawings the utility model is carried out to exemplary description above; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
