Problems solved by technology

Sampling cannot be achieved if the length of the sample taken exceeds the maximum limit or the diameter of the sample is not the caliber of the existing tool
[0003] Furthermore, in the existing laboratory rock or concrete sampling machines, during the sampling process, with the increase of the drilling depth, the drill pipe tends to swing a little from side to side, which will directly cause the side of the cylindrical sample taken out to be rough. , and sometimes there will be a large dislocation phenomenon, resulting in sampling failure, unable to be used for subsequent sample work, time-consuming, laborious and laborious
[0004] In addition, in the process of drilling and sampling, if there are cracks or joints in the rock, when the tool rotates at high speed, the specimen is easily broken at the joints, which will also lead to sampling failure
[0005] If the height of the required cylindrical sample is less than the depth of the drilling sampler, sometimes it is difficult to grasp the depth of the drilling tool. time
[0006] In addition, the existing stone grinding machine needs to continuously spray water to cool the entire grinding disc surface during grinding, which seriously wastes water resources

Abstract

The invention discloses a water-saving rock or concrete cylindrical sample production device, comprising a frame, the frame includes a horizontal guide rail, a vertical column, and a slide bar, and the vertical column and the slide bar can be slidably matched to adjust the sample The size of the installation space can make samples of any height according to the needs; the samples are installed through the clamping parts of the pressure bearing plate and the rubber plate, the samples are driven by the coaxial motor, and the grinding changes from passive to active. At the same time, there is also a grinding assembly that can slide left and right. According to the distance between the grinding assembly and the center of the sample, cylindrical samples with different diameters can be produced; the cooling water pipe slides with the vertical slider to save water and energy; the structure of the present invention It is simple and can complete the production of cylindrical samples at one time, saving time, labor and effort.

Description

Technical field [0001] The invention relates to the field of geotechnical engineering instruments, and belongs to a sample making tool, in particular to a water-saving rock or concrete cylindrical sample making device. Background technique [0002] The existing laboratory rock or concrete sampler can only take samples with a fixed diameter and a limited length. If the length of the sample taken exceeds the maximum limit or the diameter of the sample is not the caliber of the existing tool, sampling cannot be achieved. [0003] Moreover, in the existing laboratory rock or concrete sampling machine, as the drilling depth increases during the sampling process, the drill rod is prone to a little swing from left to right, which will directly cause the side of the cylindrical sample to be taken out not smooth , Sometimes there will be a big misalignment phenomenon, resulting in sampling failure, unable to be used for subsequent sample work, time-consuming and labor-intensive. [0004] In...
