Abstract
The utility model discloses an assembling type hole dilating drill which comprises a plurality of steel-made tube bodies. Internal threads and external threads are respectively machined at the upper end and the lower end of each steel-made tube body. A plurality of radial shape steel-made ribbed plates are welded around each steel-made tube body. Tube shape drill bodies are welded around each steel-made tube body through the ribbed plates. The plurality of steel-made tube bodies are vertically connected through the threads to form the hole dilating drill with sectional diameters. The diameters of the tube shape drill bodies of the hole dilating drill are requested to increase from head to tail in sequence. When a hole is dilated, the tube shape drill bodies with different diameters are changed, the assembling type hole dilating drill is suitable for grading hole dilating of well drilling at any depths, a contact face of the drill and a rock is small when the hole dilating is carried out every time, resistance is reduced, drilling efficiency is high, the drill bodies can be used repeatedly, and cost is low.
Description
Technical field
The utility model relates to the drill bit that hydrogeological mineral exploration is used, and relates in particular to reaming bit.
Background technology
At present in the large diameter borehole constructions such as the hydrology hole of solid mineral exploration, pilot hole of shaft, as the wammel using is when creeping into for the first time, and efficient is low, falls flat, and the drill bit waste is larger, so need to carry out classification reaming construction.
Summary of the invention
The purpose of this utility model provides a kind of assembly type reaming bit, solves the problem of large diameter borehole classification reaming construction.
For achieving the above object, the technical scheme that the utility model is taked is: it comprises many steel bodys, every steel body upper and lower end is processed with respectively internal thread and external screw thread, the a plurality of radial steel floors of upper welding around the every steel body, by the upper overman bit body of floor welding, many steel bodys connect to form up and down the reaming bit of a segmentation diameter by screw thread; Requiring the overman bit body diameter of reaming bit is to increase progressively successively from the beginning to the end.
The utility model has the advantages that: during reaming, by changing the overman bit body of different-diameter, applicable to any degree of depth drilling well classification reaming, drill bit and rock contact surface are less during each reaming, and resistance reduces, and drilling efficiency is high, bit body is reusable, and cost is low.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment; Among the figure take two-stage as example.
Marginal data, 1-steel body, 2-internal thread, 3-floor, 4-overman bit body, 5-external screw thread, 6-starter.
The specific embodiment
As shown in Figure 1, a kind of assembly type reaming bit, it comprises two steel bodys 1, every steel body 1 upper and lower end is processed with respectively internal thread 2 and external screw thread 5, the a plurality of radial steel floors 3 of upper welding around the every steel body 1, connect to form up and down the reaming bit of two sections diameters by internal thread 2 and external screw thread 5 by upper 4, the two steel bodys of overman bit body of floor 3 welding; Requiring the overman bit body diameter of reaming bit is to increase progressively successively from the beginning to the end.
Connect upper starter 6 during use below the reaming bit and can carry out reaming.
