Abstract

The utility model provides a hole drill. The drill body is provided with pulls to be gripped by both hands of a user. A servo motor and a plurality of fluted discs having different number of teeth are arranged between the two pulls to drive a midpoint top center and a drive spiral splice under the drill body. The midpoint top center and the drive spiral slice are made of different materials so as to meet the requirement of the field where holes are to be drilled. In this way, when holes are to be drilled, the drill shall pass through the midpoint top center first, and then shall be aligned with the hole center to drill; an undermost cutting knife under the drive spiral slice at different revolutions per minute nearby is guided to drill holes in a spiral cutting way. Through a guide opening above the cutting knife, cut material is discharged onto the ground promptly and successively through the driven spiral slice. Accordingly, the utility model is applicable for various fields, and can drill holes favorably.

Description

The structure of perforating machine for drilling hole

Technical field

The utility model relates to the structure of a kind of drilling tool, particularly perforating machine for drilling hole.

Background technology

About in soil, being the boring person of burrowing, can run into usually when the time at present in boring, because the gravity of body is down, the phenomenon that the boring work is down advanced constantly automatically; Drill bit foremost with general perforator, though it can be got out hole, and drill bit is other also to be provided with groove with the usefulness as casting, but because the speed of getting rid of is unable to catch up with drilling speed, consequently more is not easy dispatch when drill bit more down bores and goes out, so that drill bit usually is stuck, and because the soft characteristic of soil itself, when soil after drilled cavitation, the soil by hole tends to towards hole crowded, so cause the double team phenomenon of drill bit, drill bit is easier to be stuck; And when being applied to as unlike material places such as wood, cement, metals, also can be unable to catch up with drilling speed because of the speed of getting rid of, so that drilling cuttings more is not easy dispatch and goes out when drill bit more deeply bores, so that drill bit will be done drilling work on the one hand, also will expect friction mutually (discharging because have little time) with bits on the other hand, thereby also usually be stuck, and severe attrition drill bit itself, quite undesirable so really.

Therefore, the applicant must propose the utility model.

Summary of the invention

The utility model purpose is, a kind of structure of perforating machine for drilling hole is provided, and to overcome the defective of above-mentioned traditional structure, is suitable for the effect that drilling operation is carried out in various places smoothly to reach.

Structure according to a kind of perforating machine for drilling hole of the utility model, it is characterized in that, the below of body is provided with the spiral drive blade that the mid point top heart and in order to the alignment hole heart is used for rotary-cut boring and dispatch rotary-cut material, drive blade and be provided with several cutting knifes in the below, and above cutting knife, be provided with and draw mouth.

Wherein, be assembled with a power motor and several in the body and change to drive the mid point top heart respectively and to drive the fluted disc of blade rotation in order to produce different rotating speeds, each fluted disc has the different numbers of teeth.

Wherein, the both sides of body appearance is respectively equipped with a handle that supplies user's double-grip to use.

The structure of the utility model perforating machine for drilling hole, its mid point top heart and drive blade then can cooperate the place situation that will hole and adopt unlike material to make.

The utility model beneficial effect: by said structure, the structure of described perforating machine for drilling hole can produce different rotating speeds and change to change conscientiously and execute.Bore moving by the mid point top heart alignment hole heart of going ahead of the rest, with guiding week the other institute cutting knife of drive blade below that be different rotating speeds carry out real rotary-cut and hole, mouthful will be given immediately dispatch continuously to ground through driving blade by drawing of cutting knife top again, and reach and be suitable for the effect that drilling operation is carried out in various places smoothly by the material thing after the rotary-cut.

The specific embodiment

At first, please cooperate and consult Fig. 1 and Fig. 2-A, shown in the detailed description of-B: the structure of a kind of perforating machine for drilling hole of the utility model, in body 1, be provided with the handle of using for user's double-grip 11, and the fluted disc 13 of power motor 12 and several different numbers of teeth is housed in two handles, 11 middle groups, with the mid point top heart 2 and the spiral drive blade 3 that drives body 1 below respectively, and be provided with several cutting knifes 31 below driving blade 3, and above cutting knife 31, be provided with and draw mouthfuls 32, this mid point top heart 2 and drive blade 3 can be according at soil A, wooden B, cement C, different places such as metal and give and adopt unlike material made.

So, when burrowing when holing, then by the mid point top heart 2 in advance the alignment hole heart bore moving (as Fig. 3,4), be bootablely to carry out real rotary-cut at the cutting knife 31 of the week other drive blade that is different rotating speeds 3 below and holed like this, the material thing that it produced was satisfied by the mouth 32 that draws above cutting knife 31 and was thought through driving blade 3 to immediately dispatch to ground (as Fig. 5) continuously when cutting knife 31 is just carrying out rotary-cut boring work this moment; Because the diameter of cutting knife 31 rotary-cut of doing is the circle footpath greater than the mid point top heart 2, and the external diameter that drives blade 3 is again greater than the diameter of cutting knife 31 rotary-cut of doing, therefore can very quickly and smoothly the material thing that is produced after the rotary-cut be given dispatch and go out, so just can not cause the mid point top heart 2 to be subjected to phenomenon that double team is stuck.

Therefore, no matter be different places such as soil A, wooden B (as Fig. 6), cement C (as Fig. 7), metal, the utility model all can at situation at that time with collocation adapt material the mid point top heart 2 and drive blade 3 with implementation and operation, or singly be installed in mechanically utilization with the mid point top heart 2 and drive blade 3, be suitable for the effect that drilling operation is carried out in various places smoothly to reach.Even also the work of burrowing (as Fig. 8) of directly holing with fluted disc 13 collocation can not needed.
