In the prior art, the problem of fast drill bit abrasion often occurs when drilling a stratum with more cobblestones, so that the drilling cost is high and the drilling speed is slow, and people hope to find a better way to solve the problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a strenghthened type alloy button bit is provided.
The utility model discloses a realize through following technical scheme:
reinforced alloy button bit, including the drill bit body, on the preceding tip of drill bit body, it has a plurality of spherical cylindrical alloy piece and a plurality of mouth of a river to distribute, the head salient in the preceding tip of drill bit body of spherical cylindrical alloy piece, the structure at mouth of a river is wide convex structure, the side of drill bit body still is equipped with the wear-resisting protecting against shock alloy block group of a plurality of and the wear-resisting area of a plurality of steel body, wear-resisting protecting against shock alloy block group includes the wear-resisting protecting against shock alloy piece of a plurality of, and the head salient in drill bit body side of wear-resisting protecting against shock alloy piece, wear-resisting protecting against shock alloy block group and steel body wear-resisting area interval arrangement.
Preferably, the spherical cylindrical alloy pieces are spirally arranged from inside to outside on the front end part of the drill bit body.
Preferably, the front end of the drill body is provided with three water gaps.
Preferably, the wear-resistant and impact-resistant alloy block group comprises 5 wear-resistant and impact-resistant alloy blocks.
The utility model has the advantages that:
the utility model discloses a strenghthened type alloy button drill bit, the structure is ingenious, be applicable to and use to the more stratum of cobblestone, through set up the spherical surface cylindrical alloy body on the front end at the drill bit body, and the alloy body exposes the part, the wearability has not only been guaranteed, and can prevent in the use that the alloy body is struck and is split, the mouth of a river adopts wide mouth of a river circular arc structure can prevent that broken cobblestone from blocking the mouth of a river in order to guarantee the timely discharge of garrulous grit, the stability that the trompil can be guaranteed to the wear-resisting protecting impact alloy body that the side set up has further guaranteed the trompil size simultaneously, the steel body wearproof belt that the side set up can alleviate the rubble and cut rubbing to the steel body, with the life of extension drill bit, therefore, the clothes hanger is strong in practicability, and is worth promoting.
Drawings
For ease of illustration, the invention is described in detail by the following specific examples and figures.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, strenghthened type alloy button bit, including bit body 1, on the preceding tip of bit body 1, it has a plurality of spherical cylindrical alloy piece 2 and a plurality of mouth of a river 3 to distribute, the head salient of spherical cylindrical alloy piece 1 is in the preceding tip of bit body, the structure of mouth of a river 3 is wide convex structure, the side of bit body 1 still is equipped with a plurality of wear-resisting protecting against shock alloy piece group and a plurality of steel body wear-resisting area 5, wear-resisting protecting against shock alloy piece group includes a plurality of wear-resisting protecting against shock alloy piece 4, and wear-resisting protecting against shock alloy piece 4's head salient is in bit body 1 side, wear-resisting protecting against shock alloy piece group and steel body wear-resisting area 5 interval arrangements.
The spherical cylindrical alloy blocks 2 are spirally arranged from inside to outside on the front end part of the drill bit body 1.
The front end part of the drill bit body 1 is provided with three water gaps 3.
The wear-resistant and impact-resistant alloy block group comprises 5 wear-resistant and impact-resistant alloy blocks 4.
The utility model discloses a strenghthened type alloy button drill bit, the structure is ingenious, be applicable to and use to the more stratum of cobblestone, through set up the cylindrical alloy body of sphere on the preceding tip at the drill bit body, and the alloy body part of revealing, the wearability has not only been guaranteed, and can prevent that the alloy body from receiving the impact fracture in the use, the mouth of a river adopts wide mouth of a river circular arc structure can prevent that broken cobblestone from blocking the mouth of a river in order to guarantee the timely discharge of garrulous grit, the stability that the trompil can be guaranteed to the wear-resisting protecting impact alloy body that the side set up has further guaranteed the trompil size simultaneously, the steel body wearproof band that the side set up can alleviate the rubble and rub cutting of the steel body, in order to prolong the life of drill bit, therefore, the clothes hanger is strong in practicability, and is worth promoting.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
