Abstract
The utility model discloses an improved structure of a drill bit, which comprises a drill bit seat, wherein a drill table is connected with the top of the drill bit seat; a linear cutter head is arranged on the table board of the dill table; and a plurality of spherical drill teeth are respectively arranged at the two sides of the cutter head on the table board of the dill table. The improved structure is simple in structure, is easy to implement and can effectively improve the drilling effect of the drill bit.
Description
Technical field
The utility model relates to mining fitting field, is specially a kind of improvement structure of bore bit.
Background technology
Mining is the important means that realizes collection of resources, and wherein coal mining is to obtain resource indispensable activity in production in colliery in the modern energy industry.The bore bit that arrives commonly used is contained in the drill steel front end in coal mining, and in order to drilling rock, its Drilling ability of the straight bit of prior art is relatively poor, and the rock harder for some hardness can't be suitable for.
The utility model content
The utility model purpose provides a kind of improvement structure of bore bit, to solve the problem of prior art straight bit Drilling weak effect.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of improvement structure of bore bit; Comprise the bore bit seat; It is characterized in that: said bore bit seat top is connected with the discoid pricker platform that is shaped to one with the bore bit seat, and said pricker platform table top upper edge pricker platform diameter is provided with the cutter head of in-line, and said cutter head top is shaped to the pinnacle shape; Be positioned on the pricker platform table top of cutter head both sides and also be respectively arranged with a plurality of sphere pricker teeth, and the sphere pricker tooth of cutter head both sides distributes and is mutually symmetrical.
The utility model is simple in structure, is easy to realize.The cutter head at pricker platform top cooperates the Drilling of realizing rock with the pricker tooth, wherein the cutter head of pinnacle shape can make bore bit cut more easily in the rock, through a plurality of pricker teeth rock is carried out Drilling then, has improved the Drilling effect of bore bit effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1.A kind of improvement structure of bore bit; Comprise bore bit seat 1; Bore bit seat 1 top is connected with the discoid pricker platform 2 that is shaped to one with bore bit seat 1, and pricker platform 2 table top upper edge pricker platform 2 diameters are provided with the cutter head 3 of in-line, and cutter head 3 tops are shaped to the pinnacle shape; Be positioned on pricker platform 2 table tops of cutter head 3 both sides and also be respectively arranged with a plurality of sphere pricker teeth 4, and the sphere pricker tooth 4 of cutter head 3 both sides distributes and is mutually symmetrical.
