The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of augers is provided.This augers has not only kept conventional helical drill bit to lead soil soon, the advantage that efficiency is high; Also there is the ability of breaking ground strong simultaneously, at severely-weathered, middle weathering soil layer, carry out the obvious advantage of operation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of augers, it is characterized in that: comprise core bar and be arranged at least one helical blade on described core bar, the lower end of described core bar is provided with bores door, the lower end of described helical blade is provided with heel teeth, the lower end of the lower end of described helical blade and described brill door is all provided with brill tooth, heel teeth on described helical blade is arranged on the outside of boring tooth on helical blade, the outer circumferential side of described helical blade is provided with cutting cylinder, and the inwall of described cutting cylinder is fixedly connected with described helical blade.
Above-mentioned a kind of augers, is characterized in that: the lower end of described cutting cylinder is provided with a plurality of abrading blocks.
Above-mentioned a kind of augers, is characterized in that: a plurality of described abrading blocks are even laying along the circumferencial direction of cutting cylinder.
Above-mentioned a kind of augers, is characterized in that: the quantity of described helical blade is two, and two described helical blades form twin-feed spiral.
Above-mentioned a kind of augers, is characterized in that: inwall and the described helical blade of described cutting cylinder are welded to connect.
Above-mentioned a kind of augers, is characterized in that: described brill door is threaded with core bar.
Above-mentioned a kind of augers, is characterized in that: described cutting cylinder is for cylindrical.
The utility model compared with prior art has the following advantages:
1, of the present utility model simple in structure, rationally novel in design.
2, the utility model, by cutting cylinder is set, has improved the ability of breaking ground of whole drill bit, makes this drill bit can be applicable to creeping into hard soil layer.
3, the utility model, by abrading block is set, can improve cutting cylinder to the cutting efficiency of soil and cutting effect.
4, the utility model has improved the derivation efficiency to broken soil by two described helical blades.
5, of the present utility model to realize cost low, and result of use is good, is convenient to promote the use of.
In sum, the utility model is simple in structure, and rationally novel in design, functional reliability is high, long service life, and the ability of breaking ground is strong, and result of use is good, is convenient to promote the use of.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
A kind of augers as depicted in figs. 1 and 2, comprise core bar 3 and be arranged at least one helical blade 2 on described core bar 3, the lower end of described core bar 3 is provided with bores door 4, the lower end of described helical blade 2 is provided with heel teeth 6, the lower end of the lower end of described helical blade 2 and described brill door 4 is all provided with bores tooth 5, heel teeth 6 on described helical blade 2 is arranged on the outside of boring tooth 5 on helical blade 2, the outer circumferential side of described helical blade 2 is provided with cutting cylinder 7, and the inwall of described cutting cylinder 7 is fixedly connected with described helical blade 2.In the present embodiment, described cutting cylinder 7 is cylindrical.
During use, the flange 1 by core bar 3 upper ends is connected with drilling rod, specifically breaks ground in process, described cutting cylinder 7, bores tooth 5 and having nothing in common with each other effect of heel teeth 6, and its position integrated layering of formation principle of breaking ground of arranging, and its step of breaking ground is as follows:
Step 1, cutting cylinder 7 cut out a cylindrical soil body by soil, in order to subsequent parts operation;
Step 2, then bore door 4 and bore tooth 5 and formed apex point part, apex point has good breaking capacity, its installation site is cut cylinder 7 and is inside contracted 10cm～20cm, be the parts of the second echelon contact soil, this part is responsible for the cutting cylinder 7 cylindrical soil that cut out to carry out center fragmentation, and makes helical blade 2 follow-ups cut soil;
The brill tooth 5 of step 3, helical blade 2 lower ends becomes the parts of the 3rd echelon contact soil, and this part is responsible for cylindrical soil to carry out periphery fragmentation., step 2 poly-one through step and step 3, the described cylindrical soil body will be broken, and cut and split, and lose original mechanical characteristics.
Step 4, described heel teeth 6 are the parts of last contact soil, and its Main Function is: broken soil is directed to helical blade 2, to discharge hack.
As shown in Figure 1, the lower end of described cutting cylinder 7 is provided with a plurality of abrading blocks 8.Preferred way is that a plurality of described abrading blocks 8 are even laying along the circumferencial direction of cutting cylinder 7.By abrading block 8 is set, can improve cutting efficiency and the cutting effect of 7 pairs of soil of cutting cylinder.
