Abstract
The utility model discloses a pile work drilling head. The pile work drilling head comprises a drilling handle. The cross section of the drilling handle is oval, and a hard alloy drilling piece is manufactured on the top of the drilling handle in an embedding mode. The top of the drilling head is wider than the two sides of the drilling handle by 8-15mm. The hard alloy drilling piece with a cutting blade is arranged on one side of the drilling head. Compared with a drilling handle of an existing drilling head, the drilling handle is thinner, so that materials adopted in the pile work drilling head are reduced, and the cost is saved.
Description
Technical field
The utility model relates to the drill bit product technical field in a kind of infrastructure construction that is widely used in the engineerings such as highway, railway, bridge, building construction, is a kind of stake work drill bit of pile-driving machine specifically.
Background technology
At present, stake work drill bit is a nonstandard annex of pile-driving machine, and it is the cutlery on a machine drilling part, is widely used in the infrastructure construction of the engineerings such as highway, railway, bridge, building construction.Existing stake work drill bit as shown in Figure 1, Figure 2 and Figure 3 shown in, integral body be rectangular structure, thickness is identical up and down, because stake work drill bit belongs to easy loss article, timing need to be scrapped replacing, cost compare is high.
Summary of the invention
The utility model relates to a kind of work drill bit, can in the situation that improving corresponding effective utilization, reduce stake work drill bit material therefor, cuts down operating cost.
Realize this purpose, the structure that the utility model adopts is: a kind of work drill bit, comprise drillstock, described drillstock is forging forming strip steel work, the cross section of drillstock is oval, the top edge brazing sheet of hard alloy processed of drillstock, and the width of drillstock is than the little 8mm～15mm in drillstock top, one side of described drill bit is provided with the brazing sheet of hard alloy that dentation is arranged, and brazing sheet of hard alloy is provided with cutting blade.
Between described brazing sheet of hard alloy and drillstock, be provided with a cell body.
The axis of described brazing sheet of hard alloy and drillstock is parallel to each other
Its beneficial effect is: the drillstock of the more existing stake of drillstock work drill bit is thin, has reduced stake work drill bit material therefor, has saved cost.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is prior art king-pile work drill bit three-dimensional structure diagram;
Fig. 2 is the lateral view of the work of stake shown in Fig. 1 drill bit;
Fig. 3 is the front view of the work of stake shown in Fig. 1 drill bit;
Fig. 4 is the utility model three-dimensional structure diagram.
Fig. 5 is the lateral view of the work of stake shown in Fig. 4 drill bit;
Fig. 6 is the front view of the work of stake shown in Fig. 4 drill bit;
The specific embodiment
Disclosed all features in this manual, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this manual (comprising any accessory claim, summary and accompanying drawing), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
A kind of work drill bit as shown in Fig. 4, Fig. 5 and Fig. 6, comprise drillstock 1, drillstock 1 is strip steel work, the cross section of drillstock 1 is oval, one end edge brazing sheet of hard alloy 2 processed of drillstock 1, and the width of drillstock 1 is than the little 8mm～15mm in drill bit top 2, like this can be in the situation that not affecting a work drill bit and using, dwindle whole volume, reduce and use material, cut down because of the drill bit infringement of stake work and replace required cost.Drill bit 1 one sides are provided with the brazing sheet of hard alloy 3 that dentation is arranged, and brazing sheet of hard alloy 3 is provided with cutting blade 4, and brazing sheet of hard alloy 3 is parallel to each other with the axis of drillstock 1.Between brazing sheet of hard alloy 3 and drill bit 1, be provided with a cell body in order to install.
The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
