Abstract

The utility model discloses a kind of timber cement combined drill, connected and composed by timber apex point, cement apex point and drill body body three part, one end of described drill body body is connected with timber apex point, and described drill body body and timber apex point are monolithic molding; The other end of described drill body body is connected with cement apex point, and described drill body body and cement apex point are monolithic molding.The utility model has the advantage of: cement apex point and timber apex point are connected and composed by drill body body by drill bit, the two kind realizing timber and cement boring uses.

Description

A kind of timber cement combined drill
Technical field
The utility model belongs to drill bit field, particularly relates to a kind of timber cement combined drill.
Background technology
Cutter on brill, drilling machine, rig, can cause hole on workpiece or rock.Xu Chi " Goldbach's Conjecture's oil head ": " in 1956, China's bored material was somewhat nervous, and drill bit is not enough." course of work dig pit operation time, drill bit, with vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is raveled under the extruding and centrifugal action of working-blade, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.When native stream moves to without hole wall stop place, because centrifugal action hack is thrown around hole, complete the process of digging pit.
But in prior art, a kind of drill bit can only drill through the hole of a type, functional comparatively single, the hole of timber and cement just needs to select two kinds of drill bits to carry out conversion and uses, and increases manpower.
Utility model content
The technical problems to be solved in the utility model is to provide one and can be used in cement boring, can use again in timber boring, realizes the timber cement combined drill of cement, timber boring cross-reference.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of timber cement combined drill, connected and composed by timber apex point, cement apex point and drill body body three part, its innovative point is: one end of described drill body body is connected with timber apex point, and described drill body body and timber apex point are monolithic molding; The other end of described drill body body is connected with cement apex point, and described drill body body and cement apex point are monolithic molding.
Further, described timber apex point is provided with the S shape bite of horizontal positioned, and described S shape bite and timber apex point are monolithic molding, and the horizontal axis angle of described S shape bite blade and described timber apex point is 30 ~ 45 °; The front end of described timber apex point is provided with front bite, and the horizontal axis angle of described front bite and timber apex point is 15 ~ 30 °.
Further, described cement apex point is provided with the secondary bite of S shape of horizontal positioned, and the secondary bite of described S shape and cement apex point are monolithic molding, and the horizontal axis angle of the secondary bite blade of described S shape and described cement apex point is 30 ~ 45 °; The front end of described cement apex point is provided with bite, and the horizontal axis angle of described bite and cement apex point is 15 ~ 30 °.
Further, the structure of described timber apex point front end is the cone that there is helical structure on surface, and the tapering of cone is 15 ~ 30 °, and the cone of cone is high is 2 ~ 4cm.
Further, described timber apex point also includes two groove for cuttings, and described groove for cuttings extends to bottom from the start-up portion of timber apex point in a helical pattern, and brill timber apex point is divided into four parts by described two groove for cuttings uniformly.
The beneficial effects of the utility model are as follows:
1, cement apex point and timber apex point are connected and composed by drill body body by drill bit of the present utility model, and two kind thing realize timber and cement boring uses.
2, drill bit of the present utility model is provided with two groove for cuttings on timber apex point, described two groove for cuttings extend to bottom from front end in a helical pattern, along on arbitrary cross section of timber apex point, groove for cuttings is all positioned at position diametrically opposed to each other in timber apex point plane, the groove for cuttings of this symmetric figure, and row's bevel is long-pending large, it is fast that row cuts speed, not easily causes broken accumulation of cutting.
3, drill bit of the present utility model adopts surface to have the conical structural timber apex point leading section of helical structure, is drilling through in the process of hole like this, reduces stress surface, and increase borehole strength, be conducive to the automatic entrance-exit in working angles, stock-removing efficiency will improve greatly.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Drawing reference numeral: 1, front bite, 2, row cuts groove, 3, S shape bite, 4, drill body body, 5, bite, 6, the secondary bite of S shape
For making utility model object of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
The structure of timber cement combined drill of the present utility model as shown in Figure 1, a kind of timber cement combined drill, connected and composed by timber apex point 7, cement apex point 8 and drill body body 4 three part, one end of drill body body 4 is connected with timber apex point 7, and drill body body 4 and timber apex point 7 are monolithic molding; The other end of drill body body 4 is connected with cement apex point 8, and drill body body 4 and cement apex point 8 are monolithic molding, cement apex point 8 and timber apex point 7 are connected and composed by drill body body 4, and two kind thing realize timber and cement boring uses.
S shape bite 3, the S shape bite 3 that timber apex point 7 is provided with horizontal positioned is monolithic molding with timber apex point 7, and S shape bite 3 blade and timber apex point 7 horizontal axis angle are 30 ~ 45 °; The front end of timber apex point 7 is provided with front bite 1, and front bite 1 is 15 ~ 30 ° with the horizontal axis angle of timber apex point 7.
The structure of timber apex point 7 front end is the cone that there is helical structure on surface, and the tapering of cone is 15 ~ 30 °, and the cone of cone is high is 2 ~ 4cm, drilling through in the process of hole like this, reducing stress surface, increasing borehole strength, be conducive to the automatic entrance-exit in working angles, stock-removing efficiency will improve greatly.
