In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, for ordinary skill people
For member, without creative efforts, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram that the utility model discloses a kind of geologic prospect reamer that embodiment provides；
Fig. 2 is that the utility model discloses cooling water distributing damper in a kind of geologic prospect reamer that embodiment provides
Structural schematic diagram.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the utility model.On the contrary, they be only with such as
The example of the consistent device of some aspects be described in detail in the appended claims, the utility model.
It is a kind of geologic prospect reamer referring to Fig. 1, the reamer is mainly by outer tube 1, the first reamer 2, reamer
First 3, second reamer 4, correcting drill bit 5 and cooling water distributing damper 6 are constituted, wherein the upper end of reaming bit 3 is expanded with first
Hole device 2 is fixedly connected, the fixed inside for being inserted in the first reamer 2 in the lower end of outer tube 1, and passes through spot welding and the first reamer 2
It is fixedly connected, lower end surface and the platform in reaming bit 3 of above-mentioned outer tube 1 offset, the upper end of the second reamer 4 and reaming bit
3 lower end is fixedly connected, and correcting drill bit 5 is fixedly installed in the lower end of reamer 4, wherein the diameter of correcting drill bit 5 is less than reaming
The diameter of drill bit 4, referring to fig. 2, above-mentioned cooling water distributing damper 6 are rounded, and closure is installed on the top cross section of outer tube 1,
And through-hole 61 is provided on cooling water distributing damper 6, it is preferable that through-hole 61 is located at the center of cooling water distributing damper 6.
Above-mentioned geologic prospect reamer middle external tube, the first reamer, reaming bit, the second reamer and correcting drill bit
It can be selected according to the actual situation etc. specific diameter, drilling well small-bore for the diamond constructed throughout the year, by bit diameter
Point, common bore is Φ 60mm, Φ 75mm, Φ 91mm and Φ 110mm etc., wherein Φ 75mm bit diameter is that geology is general
Most common bore when looking into, looking for mine, assay sampling the advantage is that core recovery percentage is high, drilling efficiency is high, drilling is hung down
Directly spend while also reaching the sampling request of geology assay.
If by taking Φ 75mm hole diameter drill sampling as an example, if going wrong, needing in Φ 75mm hole diameter drilling process
Carry out reaming using above-mentioned Counterboring apparatus, then the selection of each component is as follows in Counterboring apparatus: outer tube 1 selects 73 outer tube of Φ, and long
Degree is 600mm, the first reamer 2 selects 91 reamer of Φ, reaming bit 3 selects 91 drill bit of Φ of heavy wall, the choosing of the second reamer 4
75 drill bit of Φ is selected with 75 reamer of Φ, correcting drill bit 5.
When carrying out reaming using above-mentioned reamer, leading for drilling direction is carried out by being located at the lowermost correcting drill bit first
Draw and correcting, and the correcting drill bit can also exclude the obstruction in front while correcting, and upper end reaming bit is avoided to expand
Phenomena such as collapsing and mounting board reaming bit occur during hole occurs, and is remarkably improved reaming efficiency, and in correcting drill bit
Correcting auxiliary under, after reaming bit reaming well head and probing well head can keep higher concentricity.In order to realize to reaming
Drill bit and correcting drill bit cool down, and are carried out in reaming procedure using the reamer, and cooling flushing water can be injected from top,
