Abstract
The utility model discloses a geological exploration drilling machine bit, comprising a bit, a bit body and a center hole in the bit body, characterized in that: a spline groove is arranged on the outer surface of the bit body, a nozzle is arranged on the lateral surface of the bit, the center hole of the bit body is communicated with the nozzle by a spray tube, the end of the bit is provided with cylindrical hard alloy center teeth and the arc transition segment of the bit is provided with hard alloy spoon-shaped teeth and cylindrical hard alloy edge teeth. The beneficial effects of the utility model are that: the geological exploration drilling machine bit uses the shaving way as the main way and the drilling efficiency is increased. The geological exploration drilling machine bit solves the problems of the prior complicated mountain layer drilling and one bit is used to form a well and the difficult problem of exchanging the bit in the middle is not present. Meanwhile, the teeth distribution of the pneumatic scraping bit on the mountain land composite layer and the selection of the material are direct towards the soft hard alternative layer, to reduce the teeth wear and prolong the service life of the bit. The geological exploration drilling machine bit solves the technical problem of the prior technology that: the drilling tool is exchanged during drilling the soft hard alternative mountain land composite layer and the drilling efficiency is low.
Description
Technical field the utility model belongs to the geological exploration techniques field, relates to a kind of geological prospecting rock drilling machine bore bit.
Background technology geological prospecting rock drilling machine bore bit is the critical component of rig, and the structure of bore bit directly influences rig drilling efficiency and cost.At present, mainly contain technology such as the probing of shallow bore hole hammer air, the probing of scraper air or the probing of scraper mud in recombination region, mountain region exploration probing mode commonly used.The problem that prior art mainly exists has: 1, shallow bore hole hammer air probing: the shallow bore hole hammer stops up easily, have to carry brill repeatedly after stopping up, and influences drilling efficiency; Impactor cylinder sleeve and piston wear are comparatively serious, penetrate layer of gravel after drilling rate slower.2, scraper air probing: be mainly used in top layer loess, need change impactor when meeting layer of gravel, otherwise drill bit wear and tear very easily, drilling efficiency is low.3, scraper mud probing: mainly the area, water source is being arranged, two kinds of modes of operation are generally arranged, a kind of is to bore soil layer with scraper earlier, penetrates layer of gravel with the probing of shallow bore hole hammer air then, after change the mud probing into, need change drill bit twice; Another kind is directly to adopt the mud probing, need not more bit change, but bit life is shorter.
The summary of the invention the purpose of this utility model is to solve prior art to exist and change drilling tool, technical problem that drilling efficiency is low in the compound stratum drilling process of soft and hard alternation mountain region, provides a kind of geological prospecting rock drilling machine bore bit, to overcome the deficiencies in the prior art.
The technical solution adopted in the utility model is: geological prospecting rock drilling machine bore bit, comprise bore bit and pricker body, establish centre bore in the pricker body, the external surface that it is characterized in that the pricker body is provided with spline, the side of bore bit is provided with nozzle, the centre bore of pricker body is communicated with nozzle by jet pipe, and the end of bore bit is provided with cylindric carbide alloy centre tooth, is provided with carbide alloy scoop chisel insert and cylindric carbide alloy heel teeth at the changeover portion of bore bit circular arc.
The beneficial effects of the utility model:, improved drilling efficiency based on scraping.Solve the difficult problem of present complicated mountain region layer probing, can use a bore bit to break into a bite well, saved the difficult problem of middle replacing bore bit.Simultaneously, the mountain region compound stratum is pneumatic to be at the soft and hard alternation stratum towards the tooth distributing position and the selecting for use of material of scraping bore bit, can reduce the wearing and tearing of tooth, prolongs the application life of bore bit.The utility model has solved prior art and has existed and change drilling tool, technical problem that drilling efficiency is low in the compound stratum drilling process of soft and hard alternation mountain region.
Appended drawings is the utility model structural representation.
The specific embodiment is with reference to accompanying drawing, the utility model geological prospecting rock drilling machine bore bit, comprise bore bit 5 and pricker body 1, establish centre bore 2 in the pricker body 1, the external surface of pricker body 1 is provided with spline 3, and the side of bore bit 5 is provided with nozzle 9, and the centre bore 2 of pricker body 1 is communicated with nozzle 9 by jet pipe 4, the end of bore bit 5 is provided with cylindric carbide alloy centre tooth 8, is provided with carbide alloy scoop chisel insert 7 and cylindric carbide alloy heel teeth 6 at the changeover portion of bore bit 5 circular arcs.
The passage of air process when the centre bore 2 in the pricker body is probing, the spline of pricker external surface can drive 1 rotation of pricker body pneumatic breaking through in the journey.
The utility model is in the drilling process of the complicated mountain region of soft and hard alternation, and the solid rock layer that cylindrical center tooth fragmentation such as gravel is the same, scoop chisel insert rotate scraping loess, red soil floor and mud stone etc. relatively than soft formation, and cylindrical heel teeth plays auxiliary scraping action; The air communication of impactor inner chamber is crossed the centre bore of pricker body and is blown out from jet pipe, nozzle, makes landwaste discharge easily.
