Description
Technical field
It the utility model is related to a kind of drill hammer.
Background technology
Drill hammer, generally includes bar portion, is placed in the head of one end of the rod and is arranged on a number of brill on head
Body, the head are provided with the end face of spherical shape with respect to the bar portion other end.But existing drill hammer, after the abrasion of its drill body
It cannot replace, so as to add production cost.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of impact for reducing production cost
Drill bit.
To achieve the above object, the utility model provides following technical solution：A kind of drill hammer, including bar portion, put
In the head of one end of the rod and a number of drill body on head is arranged on, the head is provided with respect to the bar portion other end is in
The end face of dome shape, is provided with a number of screw hole on the end face, the drill body is connected with the screw hole thread fitting.
By using technical solutions of the utility model, when drill body abrasion and cannot use after, drill body can be backed out more to renew
Drill body and be continuing with, so as to reduce production cost.
The utility model is further set：The circumference on the head is provided with a number of screw hole, and screw thread connects at screw hole
It is connected to drill body.
By using technical solutions of the utility model, depth of the drill body in screw hole of the position can be adjusted, is bored with adjusting
The counter bore diameter of head, improves versatility.
The utility model is further set：The front side on the head offers through hole, and the through hole is axial with drill bit
In a certain angle, the bar portion is in hollow setting, and the hollow parts of the through hole and bar portion are conducted.
By using technical solutions of the utility model, air-flow is flowed into the through hole of head from bar portion hollow parts, will drilled
The rock slag produced in journey is discharged in time, so as to improve the drilling efficiency of drilling machine.
The utility model is further set：The front end sidepiece on the head offers groove, wherein with the venthole phase
The groove of coincidence runs through head.
By using technical solutions of the utility model so that the discharge of rock slag is more smooth.
