The technical solution of the present invention is further described in detail with reference to the accompanying drawings and embodiments.
Referring to fig. 1 to 5, an embodiment of the present invention provides an auxiliary device for accurate sampling of a geological drilling core, including: the device comprises a diameter measuring scale 1, a sliding measuring scale 3, a core length measuring tape 5 and a core length right baffle 6; wherein, the diameter measuring scale 1, the retractable core length measuring tape 5 and the core length right baffle 6 are sequentially arranged from left to right.
The sliding measuring scale 3 is slidably mounted on the diameter measuring scale 1, similar to a slide of a vernier caliper, connected with the diameter measuring scale 1.
The bottom of diameter measurement chi 1 is provided with diameter measurement chi 1 vertically first rock core diameter baffle 4, and 3 lower extremes of slip dipperstick are provided with diameter measurement chi 1 vertically second rock core diameter baffle 31, and slip dipperstick 3 slides the back, cliies the rock core diameter with first rock core diameter baffle 4 and second rock core diameter baffle 31, can read out the rock core diameter on the scale.
A hollow core length left side draw-in groove 2 is opened to diameter measurement chi 1 right side, and this draw-in groove effect is for placing in the rock core and need measure or sampling position starting point department, if need the sampling then can insert this draw-in groove with cutting rock core with bayonet sampling sword 7.
The rightmost end of the core length measuring tape 5 is a plastic core length right side plate 6, the core length measuring tape 5 is connected with the right side of the diameter measuring ruler 1, and the concrete connection and sliding mode of the core length measuring tape 5 and the diameter measuring ruler 1 are similar to those of a vernier caliper. When sampling is needed, the core length measuring ruler is stretched, the right side plate of the core length on the right side is aligned with the end point of the core length, and the scale of the measuring ruler needs to be calculated because the length of the measuring ruler is 5cm, so that the scale of the starting point of the measuring ruler starts from 5cm, and the core length is read from the final length of the measuring ruler. When sampling is needed, an insertion type sampling knife 7 is used for inserting along the right side plate 6 of the core length so as to finish the core sampling work.
During use, cores collected during drilling work are placed elsewhere in the core box: the specific functions and the use description are as follows:

And (3) inserting the plug-in sampling knife 7 into the clamping groove 2 on the left side of the core length to cut out the starting point of the core.
Taking a core with the length of 20cm as an example, pulling the right telescopic core length measuring tape 5 until the tape reads 20cm (5 cm of the tape is considered), inserting the inserted sampling knife 7 into the core along the baffle 6 on the right side of the core length, and hammering the sampling knife hammering part 8 of the inserted sampling knife 7 by using a hammer to finish the sampling of the core with fixed length.
1/2 positions are calculated according to the recorded core diameter, the top end of the core length measuring tape 5 slides to the positions along the diameter measuring tape and is fixed, the core length measuring tape is stretched to the length scale of the sample to be sampled, the sampling knife is vertically inserted along the bottom edge of the core length measuring tape in parallel with the long axis of the core, and if the core is too hard and the sampling knife cannot be directly inserted into the core to be split into halves, the middle axis position can be drawn by using a pen with oil to prepare for a later-stage electric saw.
The above embodiments are provided to further explain the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
