The to-be-solved technical problem of the utility model is when meetting difficult through stratum such as the layer of highly weathering, dig the footage difficulty soon, seriously influence the problem of efficiency of construction. In order to solve the technical problem, the utility model provides a spiral drill bucket, including the square head seat, square head seat bottom fixedly connected with center tube. This auger drilling fill, through pick seat, pick, spiral plate isotructure, can dig the in-process soon, bottom to difficult passing through such as strong weathering layer, muck layer, metalling is convenient for prevent to influence the engineering progress because of boring to get the difficulty, the practicality of improving device, can accurately fix a position drilling point through centering quartering headstock simultaneously, and through the design of double-end spiral, can level in and level out at the drilling in-process, make the drilling fill atress even, be convenient for prevent to appear askew hole and phenomenon such as hole collapse, reduce work efficiency.

Description

Spiral drill bucket

Technical Field

The utility model relates to a drilling engineering equipment technical field specifically is a auger bit fill.

Background

The rotary drilling rig is a construction machine suitable for hole-forming operation in building foundation engineering, and its principle is that a power head is used to drive a drill rod, so that a rotary bucket can cut rock soil, then the drill rod is lifted to the outside of the hole to unload soil, and the hole-forming operation is implemented periodically. The rotary drilling rig is mainly suitable for construction of soil layers such as sandy soil, cohesive soil, silty soil and the like, and is widely applied to construction of various foundation foundations such as cast-in-place piles, continuous walls, foundation reinforcement and the like. The rotary drilling rig is used as efficient and advanced pore-forming equipment, and has more outstanding advantages when drilling in heavy-caliber construction such as high-speed rails and bridges. However, under different geological conditions, the use of rotary drilling is often limited, different drill bits need to be replaced to adapt to different stratums, particularly to stratums which are difficult to penetrate, the rotary drilling is difficult to advance, the construction efficiency is seriously affected, and phenomena such as hole bending and hole collapse are easy to occur in the drilling process.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Not enough to prior art, the utility model provides a spiral drill fill has solved when meetting difficult layer of passing through such as strong regolith, digs the footage difficulty soon, seriously influences the problem of efficiency of construction.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a spiral drill bucket, includes square head seat, square head seat bottom fixedly connected with center tube, center tube surface fixedly connected with spiral plate, spiral plate bottom fixedly connected with pick box, pick box bottom fixedly connected with pick.

The bottom of the central tube is fixedly connected with a centering four-quarter headstock.

Preferably, through holes are formed in the side wall of the side, opposite to the square head seat, and the number of the through holes is two.

Further preferably, the central tube has a hollow structure.

Further preferably, the number of the pick seats is seven.

Further preferably, the cutting pick is conical in shape.

Further preferably, the bottom of the centering four-quadrant headstock is fixedly connected with four cutting teeth.

(III) advantageous effects

The utility model provides a auger bit possesses following beneficial effect:

(1) this auger bit fill through pick box, pick, spiral plate isotructure, can dig the in-process soon, drills to the bottom that difficult passes through such as highly weathered layer, clay layer, metalling, is convenient for prevent to influence the engineering progress because of boring to get the difficulty, improves the practicality of device.

(2) This auger drilling fill can be accurate through centering quartering headstock and fix a position the drilling point, and through the design of double-end spiral, can tie in and tie out at drilling in-process, makes the drilling fill atress even, is convenient for prevent phenomenons such as askew hole and hole collapse from appearing, reduces work efficiency.

Drawings

Fig. 1 is a front view of the structure of the present invention.

In the figure: the cutting tool comprises a square head seat 1, a central tube 2, a spiral plate 3, a cutting tooth seat 4, a cutting tooth 5 and a centering four-point head seat 6.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a spiral drill bucket comprises a square head seat 1, wherein through holes are formed in the side wall of one side, opposite to the square head seat 1, of the square head seat, the number of the through holes is two, a rotary drilling rig can fix the drill bucket conveniently, a central tube 2 is fixedly connected to the bottom of the square head seat 1, the central tube 2 is of a hollow structure, a spiral plate 3 is fixedly connected to the outer surface of the central tube 2, the slag carrying capacity of the spiral drilling rig can be improved conveniently, a pick seat 4 is fixedly connected to the bottom of the spiral plate 3, the number of the pick seat 4 is seven, a pick 5 is fixedly connected to the bottom of the pick seat 4, the shape of the pick 5 is conical, through the structures of the pick seat 4, the pick 5, the spiral plate 3 and the like, a bottom layer which is difficult to penetrate, such as a highly weathered layer, a clay layer, a crushed rock layer and the like can be drilled in the rotary drilling process, the engineering progress is prevented from being influenced by the difficulty in drilling, the practicability of the device is improved, a centering four-division head seat 6 is fixedly connected to the bottom of the central tube 2, be convenient for accurate fix a position the drilling point, four picks 5 of 6 bottoms fixedly connected with of centering quartering headstock are convenient for break ground when drilling, and through the design of double-end spiral, can go into the tie out at drilling in-process level, make the drilling bucket atress even, are convenient for prevent phenomenons such as askew hole and hole collapse from appearing, reduce work efficiency.
