Abstract
The utility model relates to a geological drilling device. The diameter of drill bits of conventional drilling devices is greater than the diameter of drill rods of the conventional drilling devices, thereby causing the problems that drill holes are not straight, hole reaming is needed again, and the drilling is high in cost but low in efficiency. The geological drilling device can solve the aforementioned problems and the technical scheme for solving the problems are that: the geological drilling device comprises a drill bit which is equipped with a sleeve rod through screw threads, a drill rod is arranged inside the sleeve rod, one end of the drill rod is fixed on the drill bit through screw threads, and the diameter of the drill bit is greater than the diameter of the sleeve rod. The geological drilling device is simple and unique in structure, convenient in usage and high in efficiency, and is an innovation on geological drill devices.
Description
One, technical field
The utility model relates to drilling equipment, and particularly a kind of geology is used drilling rig.
Two, background technology
Geology is used drilling equipment now, all is the drill pipe diameter of bit diameter greater than its rear portion generally, along with the probing drilling depth increases; Drilling rod swing in boring good hole causes bit bounce during boring, causes boring not straight, and following basket is difficulty comparatively; Often need reaming again, wasted lot of manpower and material resources, production efficiency is low; Particularly performance is more outstanding under the relatively poor geological conditions of lithology, so its improvement and innovation are urgent problems.
Three, summary of the invention
According to above-mentioned situation; For overcoming the defective of prior art; The purpose of the utility model just provides a kind of geology and uses drilling rig, can solve effectively that the boring that existing drilling rig bit diameter causes greater than drill pipe diameter is straight, needs reaming again, boring cost height and inefficient problem.
The technical scheme of its solution is, comprises drill bit, through screw thread loop bar is housed on the drill bit, and drilling rod places in the loop bar, and an end of drilling rod is fixed on the drill bit through screw thread, and the diameter of drill bit is greater than the diameter of loop bar.
The utility model is simple in structure, unique, and is easy to use, and efficient is high, is the innovation on the geotechnical boring device.
Four, description of drawings
Fig. 1 is the main pseudosection of the utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further explain.
Provided by Fig. 1, the utility model comprises drill bit, through screw thread loop bar 3 is housed on the drill bit 1, and drilling rod 2 places in the loop bar 3, and an end of drilling rod 2 is fixed on the drill bit 1 through screw thread, and the diameter of drill bit 1 is greater than the diameter of loop bar 3.
In order to guarantee result of use, said loop bar 3 is a hollow round bar body.
When the utility model used, drilling rod 2 had reduced the amplitude of fluctuation of drilling rod 2 greatly through the restriction of loop bar 3; The Kong Zhi that assurance is got, following basket be success once, and the boring of each dark 30m can be saved 24 man-hours; About 2400 yuan of cost saving; Having improved production efficiency greatly, reduced the boring cost, is the innovation on the geological drilling device.
