Abstract
A core drilling machine with a dust discharge device comprises a drilling machine body. A motor is arranged at the front end of the drilling machine body. A motor cover is arranged outside the motor. A power shaft of the motor is connected with a holding device which is used for being installed with a drill head. A fan is arranged in the motor cover and on outer side of the motor. The direction of the fan port of the fan is consistent with that of the drill head. When the motor drives the drill head to high-speedily rotate a drill hole, drilling dust is produced, and the fan arranged on the outer side of the motor is capable of blowing away dust which is formed on the periphery of the drill head and discharged from the drill hole. Meanwhile, the fan can cool the drill head. The core drilling machine with the dust discharge device has the advantages of being long in service life and high in drilling efficiency.
Description
Technical field
The utility model relates to the diamond core bit that a kind of geological drilling is used.
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 purpose of this utility model has been to provide a kind of rock-core borer with row's powder device, can effectively reduce the temperature of drill bit, in time cleaning boring drillings on every side, has long service life, drills through the high characteristics of efficient.
To achieve these goals, the technical solution adopted in the utility model is: a kind of rock-core borer with row's powder device, include the rig body, front end at the rig body is provided with motor, motor is provided with motor cover outward, the line shaft of motor links to each other with the clamping device that drill bit is installed, and is provided with the air port fan consistent with the drill bit direction in motor cover, outside the motor.
The beneficial effects of the utility model are:
Since the utility model above the side of drill bit, the outside of motor is provided with fan, when holing, the driven by motor drilling bit high-speed rotary produces drillings, the fan in the motor outside blows away around the drill bit and the dust of discharging in the boring, fan can be lowered the temperature to drill bit simultaneously, have long service life, drill through the high characteristics of efficient.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operating principle are described in further detail.
Referring to accompanying drawing 1, a kind of rock-core borer with row's powder device, include rig body 1, front end at rig body 1 is provided with motor 2, the motor 2 outer motor cover 3 that are provided with, the line shaft of motor 2 links to each other with the clamping device 4 that drill bit 6 is installed, in motor cover 3, motor 2 outsides are provided with the air port fan consistent with the drill bit direction 5.
Operating principle of the present utility model is:
During use, produce drillings when the driven by motor drilling bit high-speed rotary is holed, the fan in the motor outside blows away around the drill bit and the drillings of discharging in the boring, and fan can be lowered the temperature to drill bit simultaneously, has long service life, drills through the high characteristics of efficient.
