Description
Technical field
The utility model relates to the drill bit that a kind of mine, oil drilling are used.
Background technology
At present, the drill bit that mine, oil drilling are used uses three dental drill heads mostly, and its operating principle is to use horizontal gear wheel to roll work plane, relatively is suitable for softer geological structure.The defective of prior art is: the drill body life cycle is short; When drilling harder geological structure, easy bit freezing, the probing progress is slow.
Summary of the invention
The utility model is at the deficiencies in the prior art, the drill bit that provide a kind of drill body life cycle length, be difficult for bit freezing when drilling harder geological structure, the probing progress is suitable for the mine faster, oil drilling is used.
Technical solution of the present utility model is achieved in that a kind of drill bit, form by the probing main shaft, drill body and the drill bit that are connected with drilling rod, it is characterized in that, on the probing main shaft, be provided with pinion and master gear, described drill body hollow, coating are drilled main shaft and are rotationally connected with the probing main shaft, in the space of probing main shaft and drill body formation, driven countershaft is rotatably connected on the support in the drill body space, the termination of driven countershaft is provided with transmitting gear, transmitting gear and pinion engagement, another termination of driven countershaft is provided with pinion; Driven shaft is rotatably connected on the support in the drill body space, the termination of driven shaft is provided with driven accessory whorl, driven accessory whorl and pinion, and another termination of driven shaft is provided with driven pulley, be provided with breast wheel between driven pulley and master gear, breast wheel meshes with master gear and driven pulley respectively; Be provided with internal gear at the probing spindle end, be rotatably connected to several probing countershafts in the drill body termination, the termination of probing countershaft is provided with the probing gear, and probing gear and internal gear engagement are equipped with drill bit in the termination of probing countershaft.
As a kind of improvement of the present utility model, described probing countershaft number is 2.
The beneficial effects of the utility model are, drill bit can be changed at any time according to mode of occupation, and the drill body life cycle is long, be difficult for bit freezing when the harder geological structure of probing, the probing progress is very fast, are particularly suitable for the mine, oil drilling uses.
Description of drawings
Fig. 1 is a kind of drill bit structural representation.
Among Fig. 1,1-probing main shaft, 2-internal gear, 3-probing gear, 4-probing countershaft, 5-drill bit, 6-master gear, 7-breast wheel, 8-driven pulley, 9-driven shaft, 10-driven accessory whorl, 11-pinion, 12-driven countershaft, 13-transmitting gear, 14-pinion, 15-support, 16-drill body.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, a kind of drill bit, by the probing main shaft (1) that is connected with drilling rod, drill body (16) and drill bit (5) are formed, on probing main shaft (1), be provided with pinion (14) and master gear (6), described drill body (16) hollow, coating is drilled main shaft (1) and is rotationally connected with probing main shaft (1), in the space that probing main shaft (1) and drill body (16) form, driven countershaft (12) is rotatably connected on the support (15) in the drill body space, the termination of driven countershaft (12) is provided with transmitting gear (13), transmitting gear (13) and pinion (14) engagement, another termination of driven countershaft (12) is provided with pinion (11); Driven shaft (9) is rotatably connected on the support in drill body (16) space, the termination of driven shaft (9) is provided with driven accessory whorl (10), driven accessory whorl (10) and pinion (11) engagement, another termination of driven shaft (9) is provided with driven pulley (8), be provided with breast wheel (7) between driven pulley (8) and master gear (6), breast wheel (7) meshes with master gear (6) and driven pulley (8) respectively; Be provided with internal gear (2) in probing main shaft (1) termination, be rotatably connected to 2 probing countershafts (4) in drill body (16) termination, the termination of probing countershaft (4) is provided with probing gear (3), and probing gear (3) and internal gear (2) engagement are equipped with drill bit (5) in the termination of probing countershaft (4).Its course of action is: probing main shaft (1) rotates drill bit (5) by drilling rod drive internal gear (2), probing gear (3), probing countershaft (4).Probing main shaft (1) drives master gear (6), breast wheel (7), driven pulley (8) rotation.Driven shaft (9) drives driven accessory whorl (10), pinion (11), driven countershaft (12), transmitting gear (13) rotation.Because transmitting gear (13) rotating speed, makes transmitting gear (13) greater than the rotating speed of pinion (14) and makes backward rotation by the drill body (16) that support (15) is rotationally connected around pinion (14) with it.Because be rotatably connected to 2 probing countershafts (4) in drill body (16) termination, historical facts or anecdotes has showed drill bit (5) autobiography on one side, on one side around probing main shaft (1) revolution, has accelerated the probing progress.
