Abstract
The utility model discloses a portable drilling sampling drill bit which comprises a screw thread rigid body, a clamping rigid body and a diamond rigid body. The clamping rigid body is respectively connected with the screw thread rigid body and the diamond rigid body. Screw threads are arranged at the periphery of the screw thread rigid body. A plurality of diamond casing bodies are arranged on the diamond rigid body. Each diamond casing body protrudes out of the diamond rigid body and contains diamond particles. A plurality of water outlets are formed in a bottom lip face at the bottom of the diamond rigid body. According to the portable drilling sampling drill bit, due to design of each diamond casing body protruding out of the diamond rigid body, an outer blade and an inner blade of the drill bit are guaranteed, the problem that a sampling rate is low in a intense weathering stratum and a weak weathering stratum can be solved, the drill bit can adapt to various different stratums, vibration caused by the drill bit in the process of taking samples can be reduced, disturbance to the samples is reduced and the drill bit can not be consumed too fast in the processing of sampling from a completed weathered stratum, a crushed zone or a quaternary system.
Description
Technical field
The utility model relates to the bit technique field, particularly relates to a kind of portable drill chisel bit.
Background technology
On the project organization of diamond bit in the market from upper down be the bracelet rigid body successively, form with the carcass of delivery port, different drill bits is used on different stratum.The bit matrix loss is too large when creeping into weathered layer, secondly all lower on drilling efficiency and bit life, especially creep into middle bouncing of drilling tool on the zone of fracture stratum and directly causes drill bit to burst apart, and the financial cost of drilling is improved.
The utility model content
Main purpose of the present utility model is to overcome the deficiencies in the prior art, and a kind of portable drill chisel bit is provided.
To achieve these goals, technical solution of the present utility model provides a kind of portable drill chisel bit, comprises screw thread rigid body, clamping rigid body and diamond rigid body, shown in the clamping rigid body link to each other with the diamond rigid body with described screw thread rigid body respectively;
Described screw thread rigid body is arranged with screw thread outward;
Described diamond rigid body is provided with several diamond carcasses, and described diamond carcass protrudes from the diamond rigid body, and described diamond carcass contains diamond particles;
The end labial surface of diamond rigid body bottom is provided with several delivery ports.
Further, described drill bit is hollow shape.
Further, described diamond carcass outer wall protrudes from the diamond rigid body outside.
Further, described diamond carcass inwall protrudes from diamond rigid body inboard.
Adopt technique scheme, the beneficial effects of the utility model are:
Adopt the diamond carcass to protrude from the design of diamond rigid body, outside and the inner edge of drill bit have been guaranteed, this design can solve in the low problem of severely-weathered and weak weathered stratum sampling rate, can adapt to multiple different stratum, can reduce drill bit carves and to get the vibrations that drill bit causes in the sample thief, minimizing is to the disturbance of sample, and easy consumption is not too fast for drill bit in completely decomposed stratum, zone of fracture or Quaternary system sampling.
Description of drawings
Fig. 1 is the structural representation of a kind of portable drill chisel bit of the present utility model;
Fig. 2 is the upward view of the diamond rigid body of the utility model portable drill chisel bit.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The structural representation of portable drill chisel bit of the present utility model comprises screw thread rigid body 2, clamping rigid body 3 and diamond rigid body 4 as depicted in figs. 1 and 2, shown in clamping rigid body 3 link to each other with diamond rigid body 4 with described screw thread rigid body 2 respectively; Clamping rigid body 3 mainly when unloading drill bit, makes things convenient for the tonger clamping not damage other position of drill bit;
The described screw thread rigid body 2 outer screw threads 1 that are arranged with; Major function is that fixed drill bit is connected connection with drilling tool;
Described diamond rigid body 4 is provided with several diamond carcasses 5, and described diamond carcass 5 protrudes from diamond rigid body 4, and described diamond carcass 5 contains diamond particles; Diamond carcass 5 major functions are to play shear action when carving coring, and the space between the circular diamond carcass 5 is more conducive to the discharge of rock dust;
The end labial surface of diamond rigid body 4 bottoms is provided with several delivery ports 6; Space between delivery port 6 on the low labial surface and the circular diamond carcass 5 can be got rid of rock dust.
Described drill bit is hollow shape.
Described diamond carcass 5 outer walls protrude from diamond rigid body 4 outer walls.
Described diamond carcass 5 inwalls protrude from diamond rigid body 4 inwalls.
When the rock core of getting when quarter enters the internal voids of diamond carcass, current flow into the delivery port of the low labial surface of drill bit by the gap between several diamond carcasses on the diamond rigid body inwall, by the gap between several diamond carcasses on the diamond rigid body outer wall rock dust is being carried discharge successively.
The diamond carcass of the portable drill chisel bit that this use is novel protrudes from the design of diamond rigid body, outside and the inner edge of drill bit have been guaranteed, this design can solve in the low problem of severely-weathered and weak weathered stratum sampling rate, can adapt to multiple different stratum, can reduce drill bit carves and to get the vibrations that drill bit causes in the sample thief, minimizing is to the disturbance of sample, and easy consumption is not too fast for drill bit in completely decomposed stratum, zone of fracture or Quaternary system sampling.
Described only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention such as: the shape thickness of diamond carcass, the position etc. that is embedded in drill bit.
