Abstract
The utility model discloses a drill bit, specifically a suspension digging machine rock drilling bit, including a drill handle and a drill body connected to the drill shank, wherein a tip shaped front end part alloy head is inlayed at the front end head part of the drill body, characterized in that: tip shaped edging alloy heads are provided on the side edges of the drill body. As tip shaped edging alloy heads are provided on the side edges of the drill body, the drill body is not contacted with the rock during rock drilling, so that it has no abrasion, long service life, no need of regular replacement of drill bits, high operation efficiency, and low suspended digging cost.
Description
Technical field
The utility model relates to a kind of drill bit, particularly a kind of dedicated drillbit of rotary drill used for drilling rocks.
Background technology
Existing dedicated drillbit of rotary drill used for drilling rocks structure is to have a bit sub and bit sub to be connected with drill body, is inlaid with pointed alloy head at the leading section of drill body.The drill bit of this structure has following shortcoming: because the drill body partial volume is greater than the alloy head, fashionable to rotary rock drill, the side of drill body can be wiped by the rock motor and cause wearing and tearing, after a period of time, the misrun shape can be worn in the side of drill body, greatly reduces its application life, not only lose time, operating efficiency is low, also needs to consume a large amount of drill bits, has increased outstanding scraping out originally.
Summary of the invention
Not frayed, the long service life of drill body when the purpose of this utility model provides a kind of outstanding digging, often need not more bit change, operating efficiency height, an outstanding low dedicated drillbit of rotary drill used for drilling rocks that scrapes out, overcome the deficiencies in the prior art.
Dedicated drillbit of rotary drill used for drilling rocks of the present utility model, comprise bit sub 1 and the drill body 2 that joins with bit sub 1, be inlaid with pointed leading section alloy head 6 at the front end place of drill body 2, it is characterized in that: be inlaid with pointed limit alloy head on the side of described drill body 2.
Dedicated drillbit of rotary drill used for drilling rocks of the present utility model, it is spherical that the front portion of wherein said drill body 2 is semicircle, described limit alloy head is three layers of distribution, be inlaid with back alloy head 3 at the rear portion of drill body 2 periphery, back alloy head 4 and middle front alloy head 5 in being inlaid with between back alloy head 3 and leading section alloy head 6, described back alloy head 3, middle back alloy head 4 and middle front alloy head 5 all evenly distribute on circumference.
Dedicated drillbit of rotary drill used for drilling rocks of the present utility model, back alloy head 4 and middle front alloy head 5 are five in wherein said, described back alloy head 3 is five, and the angle C between the tip of included angle B between the tip of the included angle A between the tip of middle front alloy head 5 and the tip of leading section alloy head 6, the tip of middle front alloy head 5 and middle back alloy head 4 and middle back alloy head 4 and the tip of back alloy head 3 is 30 °.
Dedicated drillbit of rotary drill used for drilling rocks of the present utility model owing to be inlaid with limit alloy head in the side of body, drill body contact with rock when boring rock, and is not frayed, long service life, often need not more bit change, operating efficiency height, hang scrape out low.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1: 1 is bit sub, is used for joining with outstanding digging machine, and 2 is drill body, and drill body 2 is structure as a whole with bit sub 1.It is spherical that the front portion of drill body 2 is semicircle, is inlaid with pointed leading section alloy head 6 at front end.On the side of drill body 2, be inlaid with pointed limit alloy head.Limit alloy head is three layers of distribution, be inlaid with back alloy head 3 at the rear portion of drill body 2 periphery, back alloy head 3 is five, back alloy head 4 and middle front alloy head 5 in being inlaid with between back alloy head 3 and leading section alloy head 6, back alloy head 3, middle back alloy head 4 and middle front alloy head 5 all evenly distribute on circumference.Wherein, middle back alloy head 4 and middle front alloy head 5 are five, and every layer alloy head mutual dislocation is provided with.Angle C between the tip of the included angle B between the tip of the included angle A between the tip of middle front alloy head 5 and the tip of leading section alloy head 6, the tip of middle front alloy head 5 and middle back alloy head 4 and the tip of middle back alloy head 4 and back alloy head 3 is 30 °.The dedicated drillbit of rotary drill used for drilling rocks of this structure drill body when operation does not contact with rock, and is not frayed.
