Abstract
The invention provides a vacuum three-wing drill for a wave pressure drilling machine, comprising a columniform drill body with an internal thread hole. The head of the drill body is provided with three drill wings at equal intervals, and the three drill wings outwards incline to the central axis of the drill body. Each drill wing comprises a planar drill wing belly, a cambered surface drill wring inner back and a cambered surface drill wing outer back, wherein the drill wing inner back and the drill wing outer back are crossed to a ridge. The vacuum three-wing drill is characterized in that the head position of the drill body between every two adjacent drill wings is provided with a cambered surface working side face, the joint of each drill wing belly and the working side face forms an arc line, the drill wing inner back and the working side face are in smooth transition, and each drill wing belly and drill wing inner back of the adjacent drill wing as well as the working side face together form a dump tank. The vacuum three-wing drill with the structure, which is used for the wave pressure drilling machine, is beneficial to the discharge of slagcharge while ensuring the strength of the drill.
Description
Technical field
The present invention relates to a kind of rock rock drilling machinery, a kind of vacuum three-wing bit that is used for the wave pressure rig of using on particularly a kind of hammer drill.
Background technology
Existing rock bit are provided with three to four brill wings at the head of cylindrical drill body, form ash pit between the head of the brill wing and drill body, in the rock drilling punching process, drill bit promptly moves to have simultaneously vertically downward and rotates, and the eliminating that should be beneficial to slag charge this moment guarantees that again drill bit has enough intensity not damage.And present drill bit is for guaranteed strength, and it is generally thicker than cylindrical drill body with the binding site of drill bit to bore the wing, is unfavorable for the eliminating of slag charge.
Summary of the invention
The object of the present invention is to provide a kind of deslagging, vacuum three-wing bit that is used for the wave pressure rig that intensity is high of being beneficial to.
The object of the present invention is achieved like this: a kind of vacuum three-wing bit that is used for the wave pressure rig, comprise cylindrical drill body with internal thread hole, this drill body head equidistantly is provided with three brill wings of inclining to described drill body central axis outward, the described brill wing comprises that a plane brill wing belly, the interior back of the body of the arc surfaced brill wing and an arc surfaced bore the wing and carry on the back outward, the outer back of the body of the back of the body and the described brill wing intersects at a ridge in the described brill wing, and it is characterized in that: the drill body head position between described per two adjacent brill wings is provided with the work side of arc surfaced; Described brill wing belly becomes a camber line with the connecting portion of described work side, and the back of the body seamlessly transits with described work side in the described brill wing; The back of the body and described work side constitute ash pit jointly in the brill wing of the described brill wing belly and the adjacent brill wing.
Further, the cambered surface radius of described each work side is 55mm～65mm.
Further, the cambered surface radius of described each work side is 58mm.
Further, described each work side all has a cooling hole that communicates with the internal thread hole of described drill body.
Further, described three outer rims of boring the outer back of the body of the wing are inscribed within same circle, and this diameter of a circle is 80mm.
Further, described drill body external diameter is 47.01mm, and the drill bit entire length is 110mm.
Further, the length that described drill body external surface is provided with two symmetries is the installation groove of 29mm, the described drill body afterbody 15mm of right part distance of described installation groove.
Beneficial effect of the present invention is: because the drill body head position between per two adjacent brill wings is provided with the work side of arc surfaced, therefore be beneficial to the discharge of slag charge when guaranteeing drill bit intensity.
