Abstract
The utility model discloses a drill without earth fetching, which comprises a connecting head and a drill connected with the connecting head, and is characterized by further comprising an upper cone tube, a lower cone tube, cylinder and an upper helical blade and a lower helical blade that are respectively arranged on the upper cone tube and the lower cone tube, wherein the upper cone tube is arranged at one end of the upper part of the drill, one end of the upper cone tube, connected with the connecting head, is connected with the lower cone tube through the cylinder which is arranged in the middle of the drill, and the lower cone tube is arranged at the lower part of the drill. The drill without earth fetching is easy to manufacture, low in manufacturing cost, and simple, convenient and fast in actual operation, and the upper helical blade and the lower helical blade with opposite directions of rotation are combined with the upper cone tube and the lower cone tube, so that the drill can be used for drilling in places with loose soil without earth fetching by lifting the drill, thus improving working efficiency, saving a large amount of fuel, and creating greater economic value.
Description
Technical field
The utility model relates to a kind of drill bit that do not fetch earth, and belongs to the piling machinery field.
Background technology
Drill bit is the boring means that is applied on the rotary drilling rig, what great majority were used on the domestic market at present all is the various drill bits that fetch earth, drill bit as forms such as single open-door, double doors, the scope of application of this drill bit is wider, but when in boring procedure, particularly holing in the comparatively loose place of soil property, that need not stop takes out drill bit, the native slag of draining and producing in the boring procedure, so not only reduce operating efficiency, and because drill bit is heavier, do not stop drill bit is mentioned casting the time, have bigger energy waste.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of drill bit casting that do not need to mention when the punching of the soil is porous place is provided, can directly the native slag that produces be pressed in around the hole wall, and increase work efficiency, reduce the drill bit that do not fetch earth of energy consumption.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of drill bit that do not fetch earth, comprise connector and the drill bit that is connected with connector, it is characterized in that: also comprise the circular cone tube, down circular cone tube, cylinder and be separately positioned on the circular cone tube and following circular cone tube on last helical blade and following helical blade, last circular cone tube is arranged on drill bit top one end and is connected an end with connector by circular cone tube under the cylinder connection, cylinder is arranged on the middle part of drill bit, and following circular cone tube is arranged on the bottom of drill bit.
Described to go up helical blade and following helical blade be mutual derotation to blade.
Described cylinder is provided with elongated muscle, and is provided with air vent in the drill bit that do not fetch earth.
When the rotary drill machine is holed in the place that the soil is porous, the ground that the brill tooth of drill bit and leading drill bit take out is along helical blade rising down, when ground rises to down circular cone tube below, reduce gradually in space between following circular cone tube and the borehole wall, when ground continues to increase and the space is limited constant, not needing to mention drill bit like this when ground continues to increase fetches earth, following circular cone tube just can be pressed into ground hole wall on every side, the cylinder on circular cone tube top can be further with the ground compacting under drill bit was arranged in traveling process, prevent that ground from coming off, and elongated muscle is set on cylinder increases frictional force, more solid when pressing ground, when operation is finished when mentioning drill bit, the drill bit opposite spin, at this moment with following helical blade derotation to last helical blade lighter and can be pressed into hole wall again when drill bit is being mentioned with the ground that last circular cone tube comes off above drill bit, the cylinder of last circular cone tube bottom setting is the compacting ground equally further.
In order to prevent that when mentioning drill bit the drill bit below produces vacuum, makes borehole collapse, therefore is provided with air vent in boring.
The beneficial effect that the utility model had is: make simple, cost is low, simple, convenient when practical operation, quick, last helical blade that rotation direction is opposite and following helical blade combine with last circular cone tube and following circular cone tube, not needing to mention drill bit in the time of can holing in the place that the soil is porous fetches earth, increase work efficiency, and can save a large amount of fuel, create bigger economic worth.

Wherein: 1, connector; 2, go up helical blade; 3, go up the circular cone tube; 4, cylinder; 5, following circular cone tube; 6, following helical blade; 7, bore tooth; 8, leading drill bit; 9, elongated muscle; 10, air vent
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As Fig. 1～shown in Figure 2: a kind of drill bit that do not fetch earth, comprise connector 1 and the drill bit that is connected with connector 1, also comprise circular cone tube 3, down circular cone tube 5, cylinder 4 and be separately positioned on circular cone tube 3 and following circular cone tube 5 on last helical blade 2 and following helical blade 6, last circular cone tube 3 is arranged on drill bit top one end and is connected an end with connector 1 by circular cone tube 5 under cylinder 4 connections, cylinder 4 is arranged on the middle part of drill bit, following circular cone tube 5 is arranged on the bottom of drill bit, described cylinder 4 is provided with elongated muscle 9, and is provided with air vent 10 in drill bit.
When the rotary drill machine is holed in the place that the soil is porous, the ground that the brill tooth 7 of drill bit and leading drill bit 8 take out is along helical blade 6 risings down, when ground rises to down circular cone tube below 5, reduce gradually in space between following circular cone tube 5 and the borehole wall, when ground continues to increase and the space is limited constant, not needing to mention drill bit like this when ground continues to increase fetches earth, following circular cone tube 5 just can be pressed into ground hole wall on every side, the cylinder 4 on circular cone tube 5 tops can be further with the ground compacting under drill bit was arranged in traveling process, prevent that ground from coming off, and elongated muscle 9 is set on cylinder 4 increases frictional force, more solid when pressing ground, when operation is finished when mentioning drill bit, the drill bit opposite spin, at this moment with following helical blade 6 derotations to last helical blade 2 lighter and can be pressed into hole wall again when drill bit is being mentioned with the ground that last circular cone tube 3 comes off above drill bit, the cylinder 4 of last circular cone tube 2 bottoms setting is the compacting ground equally further.
In order to prevent that when mentioning drill bit the drill bit below produces vacuum, makes borehole collapse, therefore in drill bit, be provided with air vent 10.
