Description
Technical field
This application involves a kind of drill bits, especially a kind of to be applied to the drill bit containing rubble earth-boring.
Background technology
Bite cutting drilling is driven by the rotation of drilling rod when drill works, the soil to get off is cut and is blended in drilling
In liquid, soil zone is portalled outer drilling by drill-in fluid, if the rubble containing bulk in drill-in fluid, it will block drilling rod, cause to bore
Slag cannot be discharged and cannot normally creep into.
Invention content
This application provides it is a kind of can be in the drill bit containing rubble earth-boring.
The application is achieved by the following technical solution：
A kind of drill includes the headstock gear and bite of drum, drum；Drum setting is described in drilling rod lower end
Drum is involuted by the first half barrels with the second half barrels, and the first half barrels of upper end is arranged the first hanging nose, and the first half barrels pass through first
Hanging nose is hung on the left of drilling rod lower end；The second half barrels of upper end is arranged the second hanging nose, and the second half barrels are hung on by the second hanging nose
On the right side of drilling rod lower end；The first half barrels of the upper left-hand and the lower left side of drilling rod are hinged by the first oil cylinder, and described second
It is hinged by the second oil cylinder on the right side of half barrel of upper right and the lower part of drilling rod.
Angularly disposed multiple first orifice plates on the first half barrels of inner walls, it is angularly disposed multiple on the second half barrels of inner walls
Second orifice plate, the first orifice plate are staggered with the second orifice plate；The first half barrels of lower end is arranged the first bite, under the second half barrels
The second bite of end setting.
The application has the advantages that：
Present applicant proposes it is a kind of can be in the drill bit containing rubble earth-boring.
Description of the drawings
The application is further described below in conjunction with the accompanying drawings：
Fig. 1 is the structural schematic diagram of the application.
In figure：1. drilling rod, 2. first oil cylinders, 3. second oil cylinders, 4. first hanging noses, 5. second hanging noses, 6. the first half barrels, 7.
The second half barrels, 8. abutment joints, 9. first orifice plates, 10. rubbles, 11. first bites, 12. second bites, 13. tooth heads, 14.
Second orifice plate.
Specific implementation mode
Attached drawing be the application a kind of specific embodiment, the embodiment drill bit include drum, drum headstock gear and cut
Sharpener；In 1 lower end of drilling rod, the drum is involuted by the first half barrel 6 with the second half barrel 7 for drum setting, the first half barrels
Upper end the first hanging nose 4 is set, the first half barrels are hung on by the first hanging nose on the left of 1 lower end of drilling rod；The second half barrels of upper end is set
Set the second hanging nose 5, the second half barrels are hung on by the second hanging nose on the right side of drilling rod lower end；The first half barrels of the upper left-hand and brill
The lower left side of bar is hinged by Ffirst cylinder 2, passes through second on the right side of the lower part of the second half barrels of the upper right and drilling rod
Oil cylinder 3 is hinged.
Angularly disposed multiple first orifice plates 9 on the first half barrels of inner walls are angularly disposed more on the second half barrels of inner walls
A second orifice plate 14, the first orifice plate interacts setting with the second orifice plate；The first half barrels of lower end is arranged the first bite 11, and the second half
The second bite 12 is arranged in the lower end of bucket.
Multiple apertures are set on first orifice plate.
Multiple apertures are set on second orifice plate.
The upper end of the drum is connected to the lower end of drilling rod.
Multiple tooth heads are set on first bite.
Multiple tooth heads are set on second bite.
When the application works, the rotation of drilling rod drives the first bite and the second bite to rotate by drum, and first cuts
Sharpener and the second bite stir the soil in soil layer with rubble in rotation, and under the action of suction pump, soil and rubble are mixed in
Drum is entered by the base opening of drum in drill-in fluid, rubble falls by the collision of first orifice plate, the second orifice plate on top in lower part
The first orifice plate, on the second orifice plate, drill-in fluid and soil enter drilling rod by the suitable for reading of drum, are discharged by the pipeline on drilling rod top；
When rubble reaches a certain amount of, drum is proposed by drilling rod, starts the first oil cylinder, the second oil cylinder, opens the first half barrels and the second half
Abutment joint between bucket, outwells rubble, recloses the abutment joint between the first half barrels and the second half barrels, comes back in drilling and bore
Into.
