Abstract
Stake machine drill head suitable for complicated barrier in underground, drilling rod (1) hypomere outer wall coils screw blade (2), and moreover, end shovel (3) is connected to this screw blade (2) lower extreme, and this end shovel (3) has sharp -pointed straight flange cutting part, simultaneously, tail fin (4) is connected to this screw blade (2) upper end, and tail fin (4) tail end sharply turns up. Have fine excavation soil capacity, the soil resistance that reduces the drill bit simultaneously and receive, and then improve excavation speed, the drill bit fast turn -round can cut secret barrier, the clear hole of pore -forming of being convenient for. The soil that excavates can be relaxed sends the screw blade to, and the desorption drag reduction is remarkably productive, reduces the possibility of rig adhesion, the working resistance of pile driver reduces, it takes off native effect to make the drill bit have the stronger ability of burying and better.
Description
Technical field
The utility model relates to piled foundation, clear hole construction equipment technical field, is especially applicable to the stake machine drill head of underground complex barrier thing.
Background technology
At present, in engineering construction, screw pile driver is as a kind of common engineering machinery, in the engineerings such as bridge, roadbed and tunnel, have important application.The drill bit that screw pile driver is conventional is made up of drilling rod, apex point, brill pick and spiral guide sheet etc., and screw blade is fixed on drilling rod, and apex point and brill pick are welded on boring bar head, and become inseparable one with drilling rod, drilling rod is hollow-core construction.There is following problem in the piling drill bit of this kind of structure: in the process of piling, screw blade Clay Problem is serious, apex point and brill pick serious wear in the process of piling, apex point force structure is unreasonable, in the piling process of reality, above problem can have a strong impact on piling efficiency, extend the engineering time, meanwhile, the life-span of drilling bit of pile engine is reduced.
In addition, root pile machine augers gets the nod in the practice in the fields such as root pile construction and clear hole construction.In improvement opportunity, root pile machine is applied widely because it is light, operability is high.But constantly to transform in large quantity in city and under the background that upgrades, construction environment becomes increasingly complex, particularly underground obstacle situation.
Utility model content
The purpose of this utility model is to provide the stake machine drill head being applicable to underground complex barrier thing, provides the metal spiral drill bit of a kind of complicated underground obstacle situation tree root ram machine construction, the construction of clear hole.
The purpose of this utility model will be realized by following technical measures: comprise drilling rod, screw blade, end shovel and tail fin; Drilling rod hypomere outer wall coiled helical blade, and shovel at the bottom of this screw blade lower end connection, this end spader has sharp-pointed straight flange blade; Meanwhile, this screw blade upper end connects tail fin, and tail fin tail end sharply turns up.
Especially, in aforementioned, drilling rod lower end is outstanding spherical crown shape.
Especially, screw blade is two and mutually staggers to coil outside drilling rod.
Especially, it is outer more than one week that screw blade is around in drilling rod, is namely greater than 360 °.
Especially, there are spindle or axis hole in drilling rod upper end, and lockable mechanism.
Especially, all identical with the angle of the center line that drilling rod axis is intersected and drilling rod axis arbitrarily on screw blade center line curved surface.
Advantage of the present utility model and effect: have and well excavate soil capacity, reduce the soil resistance suffered by drill bit simultaneously, and then improve excavation speed, drill, can cut underground obstacle, is convenient to the clear hole of pore-forming.The soil excavated can send screw blade to easily, and desorption drag-reduction effect is given prominence to, and reduces the possibility that rig adheres to; The working resistance of pile driver reduces; Drill bit is made to have stronger ability of burying and take off native effect preferably.Easy for installation simple and direct, in stable condition during work, dependable performance is durable.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: drilling rod 1, screw blade 2, end shovel 3, tail fin 4.
Detailed description of the invention
The utility model principle is, augers is by driven by engine quick rotation, and cutting underground obstacle, reaches the effect of pile sinking.
The utility model comprises: drilling rod 1, screw blade 2, end shovel 3 and tail fin 4.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, drilling rod 1 hypomere outer wall coiled helical blade 2, and also shovel 3 at the bottom of this screw blade 2 lower end connection, this end shovel 3 has sharp-pointed straight flange blade; Meanwhile, this screw blade 2 upper end connects tail fin 4, and tail fin 4 tail end sharply turns up.
In aforementioned, drilling rod 1 lower end is outstanding spherical crown shape.
In aforementioned, screw blade 2 is two and mutually staggers to coil outside drilling rod 1.
In aforementioned, it is outer more than one week that screw blade 2 is around in drilling rod 1, is namely greater than 360 °.
In aforementioned, there are spindle or axis hole in drilling rod 1 upper end, and lockable mechanism.
In aforementioned, the center line that screw blade 2 center line curved surface intersects with drilling rod 1 axis is arbitrarily all identical with the angle of drilling rod 1 axis.Can reduce soil resistance to greatest extent like this, maintenance is simultaneously crept into more stable.
In aforementioned, screw blade 2 evenly coils outside drilling rod 1.
In the present embodiment, drill bit is helicoidal structure, metal quality.Screw blade 2 can utilize discoid cutter or finger-like cutter through milling cutter or emery wheel, and cylindrical work processes helicla flute; Be connected with stake owner lever by augers, motor can drive driving lever again, and driving lever drives augers quick rotation again, fly-cutting underground obstacle.
In the utility model, helical form drill bit is connected with stake driving lever, driven by engine driving lever, and drives augers quick rotation.When operation, but make pile driver have good soil mining ability, can ground pressure be disperseed, reduce to touch native area, thus reduce soil adhesion, reduce soil resistance; Improve application life and the operating efficiency of drill bit.
In the embodiment above, not and other necessary technologies of enforcement etc. of relating to described adopt prior art, enumerate detailed description no longer successively.
