Abstract
The utility model relates to an imbedded composite wear-resisting rushing head drill rod which comprises a drill rod head, an internal support frame, a drill rod body, a mounting end face and positioning pins. The internal support frame is arranged in the drill rod body, and one end of the drill rod body is provided with the drill rod head. The other end of the drill rod body is provided with the positioning pins. The mounting end face is arranged on the drill rod body. The imbedded composite wear-resisting rushing head drill rod is simple in structure, and reasonable in design. The internal support frame is arranged in the drill rod body so as to increase strength. In crushing work, the drill rod is wear-resisting, solid, not easy to break down, and high in work efficiency, and reduces usage cost.
Description
Technical field: the utility model relates to the wear-resisting crushing head drill steel of a kind of Cast-in Bonding.
Background technology: at present, existing crushing head Rod structure design is unreasonable, does not have inner supporting frame, intensity low in the drill steel body, during broken work, drill steel is not wear-resisting, and is not firm, easily fractures, and needs often to change drill steel, not only waste time and energy, inefficiency, and increased use cost.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of Cast-in Bonding wear-resisting crushing head drill steel, and it has mainly solved does not have inner supporting frame in the existing crushing head drill steel body, intensity is low, and drill steel is not wear-resisting, and the problem such as easily fracture.The purpose of this utility model be achieved in that the wear-resisting crushing head drill steel of Cast-in Bonding by: drill head, inner supporting frame, drill steel body, end face is installed, alignment pin consists of.Inner supporting frame is installed in the drill steel body, and drill steel body one end is provided with drill head, and the other end is equipped with alignment pin, and the drill steel body is provided with the installation end face.This product structure is simple, and is reasonable in design, in the drill steel body inner supporting frame is housed, and increased intensity, and during broken work, drill steel is wear-resisting firm, is not easy to fracture, and high efficiency has reduced use cost.
Description of drawings:
Accompanying drawing 1 is the structural representation of the wear-resisting crushing head drill steel of the utility model Cast-in Bonding.
1-drill head, 2-inner supporting frame, 3-drill steel body
