Abstract
A rock-core drill comprises a drill body, a motor is arranged at the front end of the drill body, a reduction gear set is arranged on a power shaft of the motor and is meshed with the inner cavity wall of a rotor of a dust fan, a drill bit is mounted at the front end of the power shaft, drilling dust is generated when the motor drives the drill bit to rotate at a high speed for drilling, and the dust fan is used for blowing away dust surrounding the drill bit and discharged from a drill hole under drive of the reduction gear set. Besides, the dust fan is capable of cooling the drill bit, and accordingly the rock-core drill has the advantages of long service life and high drilling efficiency.
Description
Technical field
The present invention relates to a kind of rock-core borer.
Background technology
Existing rock-core borer, being used for creeping into the interbedding of soft and hard rocks rock has certain effect, but because drill bit when high speed rotating, can produce high temperature, if untimely cooling can make the blade of pointed tooth easy to wear, thereby reduces bit life; This type drill bit can not effectively be arranged powder simultaneously, causes drillings to sinter piece under the baking of drill bit high temperature, affects drill bit and drills through efficient.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of rock-core borer, can effectively reduce the temperature of drill bit, in time cleaning boring drillings on every side, have long service life, drill through the high characteristics of efficient.
To achieve these goals, the technical solution used in the present invention is: a kind of rock-core borer, include the rig body, front end at the rig body is provided with motor, the train of reduction gears that the line shaft of motor is provided with, train of reduction gears is meshed with the rotor internal cavity wall of dust discharge fan, and the line shaft front end is installed drill bit.
The invention has the beneficial effects as follows:
Because motor of the present invention links to each other with the dust discharge fan by train of reduction gears, when holing, the driven by motor drilling bit high-speed rotary produces drillings, the dust discharge fan blows away around the drill bit under the drive of train of reduction gears and the dust of discharging in the boring, simultaneously dust discharge fan can be lowered the temperature to drill bit, have long service life, drill through the high characteristics of efficient.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operating principle are described in further detail.
Referring to accompanying drawing 1, a kind of rock-core borer includes rig body 1, is provided with motor 2 at the front end of rig body 1, the train of reduction gears 5 that the line shaft 3 of motor 2 is provided with, and train of reduction gears 5 is meshed with the rotor internal cavity wall of dust discharge fan 6, and line shaft 3 front ends are installed drill bit 4.
Operating principle of the present invention is:
During use, produce drillings when the driven by motor drilling bit high-speed rotary is holed, the dust discharge fan blows away around the drill bit under the drive of train of reduction gears and the dust of discharging in the boring, and simultaneously dust discharge fan can be lowered the temperature to drill bit.
Claims (1)
