In the process of anticlockwise tunneling of the drilling tool, the powder can be more easily discharged along the eccentric chute, and the powder discharge effect is obviously improved; the resistance of the cuttings is reduced, so that the drilling and digging become more powerful, the drilling and digging speed is increased, and the working efficiency is increased; relatively speaking, the wind pressure can be reduced, and the energy is saved.

Description

Self-powder-discharging eccentric core drill

Technical Field

The utility model relates to a core bores, especially relates to a from eccentric core bores of arranging powder.

Background

The drilling tool is a tool used for drilling holes, drilling holes and the like, and mainly comprises a drilling (well drilling) tool, a metallurgical furnace drilling tool and the like, all components of the drilling tool are made of high-quality seamless steel pipes, the drilling tool has excellent physical and mechanical properties so as to bear alternating load, fatigue and abrasion of the drilling tool in the drilling process, the deeper the drilling hole is, the higher the requirement on the performance of the drilling tool is, and the drilling tool needs to be scrapped due to abrasion and corrosion after a certain working period.

The core drill is one of drilling tools, the use of the core drill is very wide, but the powder discharging structure on the existing core drill is generally single, the powder discharging structure is uniformly distributed and centered, the powder discharging effect is not ideal, the tunneling resistance of a drill bit is large, the resistance of a rock stratum is also large, the powder discharging effect is obviously reduced, and the drilling speed and the working efficiency are reduced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of prior art, the utility model provides a from arranging eccentric rock core of powder and boring, the row's powder structure that can solve on the current rock core drilling tool all is more single problem usually.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a from eccentric core drill of arranging powder, including the drilling tool, the top fixedly connected with drill bit main part of drilling tool, centripetal chute and eccentric chute have been seted up respectively to the surface of drill bit main part, the quantity of centripetal chute and eccentric chute is three.

As an optimized technical scheme of the utility model, the radial chute trislot equipartition to radial chute and axis contained angle 20.

As an optimized technical scheme of the utility model, eccentric chute trislot equipartition to eccentric chute and axis contained angle 10.

As an optimal technical scheme of the utility model, the surface of drilling tool is provided with the screw thread.

As an optimized technical scheme of the utility model, the top fixedly connected with drill point of drill bit main part to the quantity of drill point is a plurality of.

As an optimized technical scheme of the utility model, the eccentric chute is eccentric unanimous.

Compared with the prior art, the utility model discloses the beneficial effect that can reach is:

the utility model changes the original centripetal circular groove powder discharging structure into a combined structure of a centripetal chute and an eccentric chute, so that the powder can be more easily discharged along the eccentric chute in the process of anticlockwise tunneling of the drilling tool, and the powder discharging effect is obviously improved; the resistance of the cuttings is reduced, so that the drilling and digging become more powerful, the drilling and digging speed is increased, and the working efficiency is increased; relatively speaking, the wind pressure can be reduced, and the energy is saved.

FIG. 2 is a front view of the structure of the present invention;

fig. 3 is a top view of the structure of the present invention.

Wherein: 1. drilling tools; 2. a drill bit body; 3. a centripetal chute; 4. an eccentric chute; 5. a thread; 6. and (4) drilling a tip.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1-3, the utility model provides a self-discharging eccentric core drill, including drilling tool 1, the top fixedly connected with drill bit main part 2 of drilling tool 1, centripetal chute 3 and eccentric chute 4 have been seted up respectively to the surface of drill bit main part 2, and the quantity of centripetal chute 3 and eccentric chute 4 is three.

The centripetal inclined grooves 3 are evenly distributed with three grooves, and the included angle between the centripetal inclined grooves 3 and the axis is 20 degrees.

The three grooves of the eccentric chute 4 are uniformly distributed, and the included angle between the eccentric chute 4 and the axis is 10 degrees.

The outer surface of the drill 1 is provided with threads 5.

The top of the drill bit body 2 is fixedly connected with drill points 6, and the number of the drill points 6 is several.

The eccentric chutes 4 are eccentric uniformly.

The specific working principle is as follows: install drilling tool 1 through screw thread 5 and use, arrange the powder structure change for the integrated configuration of entad chute 3 and eccentric chute 4 through the circular recess that will be entad originally, at the in-process that drilling tool 1 anticlockwise tunnelled like this, make the cuttings discharge along eccentric chute 4 more easily, the resistance of cuttings diminishes, makes to bore and digs and become more powerful, promotes and bores the speed of digging.

The utility model discloses the beneficial effect that can reach is: the utility model can discharge the powder more easily along the eccentric chute in the process of the drilling tool driving anticlockwise, thus obviously improving the powder discharge effect; the resistance of the cuttings is reduced, so that the drilling and digging become more powerful, the drilling and digging speed is increased, and the working efficiency is increased; relatively speaking, the wind pressure can be reduced, and the energy is saved.

The embodiments of the present invention are not limited to the above embodiments, and according to the contents of the above embodiments of the present invention, the above preferred embodiments can also make modifications, replacements or combinations of other forms by using conventional technical knowledge and conventional means in the field without departing from the basic technical idea of the present invention, and the obtained other embodiments all fall within the scope of the present invention.
