[0029] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, the embodiments described below with reference to the drawings are exemplary, and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0030] Please see Figures 1-6 A weak interlayer sample preparation device, including container 1, the container 1 has open end, and the bottom of container 1 is located at the opposite end of open end on container 1, and the bottom of container 1 is provided with mounting hole 11, and the bottom of container 1 is installed with sampling device at mounting hole 11, and the sampling device is used to take out the weak interlayer sample in the container 1.

[0031] In the embodiment of the present utility model, when in use, the stone raw material containing the weak interlayer is placed in the container 1, and polyvinyl alcohol transparent glue is poured into the container 1 to completely cover the stone. After the glue is completely dried and solidified, a sample is formed. Finally, the sampling device is passed through the mounting hole 11 to eject the solidified sample in the container 1. Finally, a rock cutter is used to cut off the excess colloid and irregular rock mass on the upper and lower plates of the sample, and the surface of the upper and lower plates of the rock are further polished to ensure that the flatness of the upper and lower plates of the sample meets the sample requirements. At the same time, the weak interlayer in the sample is made parallel to the surface of the upper and lower plates, so that when the sample is placed on the workbench, the weak interlayer can be in a horizontal state, and the colloid on the periphery of the weak interlayer is melted by a heating rod or other heating device, and the sample preparation work is completed, waiting for subsequent tests on the weak interlayer.

[0032] Compared with the traditional method of directly cutting and sampling stone rough materials, which has a greater probability of damaging the samples, the device in the embodiment of the utility model coats the stone rough materials with glue and then takes them out for cutting processing, so that the stone rough materials will not collapse during the cutting process. At the same time, the position of the weak interlayer in the sample product can be adjusted according to the cutting direction, so that the weak interlayer is in a horizontal state, which is convenient for subsequent testing of the weak interlayer and can effectively solve the problems of low sampling efficiency and low yield in the existing technology.

[0033] In order to facilitate the removal of the sample from the container 1 , an isolation layer, such as a layer of paraffin, may be applied to the inside of the container 1 .

[0034] Furthermore, a plurality of first support rods 12 are installed at the bottom of the container 1. The plurality of first support rods 12 are arranged in an array at the bottom of the placement cylinder 1.

[0035] By providing multiple first support rods 12, when placing a stone material containing a weak interlayer, it can be placed on the first support rods 12. After pouring glue to form it, the bottom of the stone material will also contain colloid. When the piston push rod 2 applies a top force to the bottom of the sample, the force can act on the colloid, preventing excessive top force from damaging the bottom of the sample. This improves the device's ability to protect the sample and further improves the sample preparation yield. Of course, to facilitate sample removal, the first support rod 12 can be a threaded rod, and after the sample solidifies, the first support rod 12 can be unscrewed.

[0036] Furthermore, multiple second support rods 13 are mounted on the sidewalls of container 1. These second support rods 13 are threaded rods. These multiple second support rods 13 can be used to horizontally secure the sample, preventing the rough stone from shaking when the colloid is poured in, thereby improving the stability of the device. To remove the sample, after the sample has solidified, the second support rods 13 are first unscrewed.

[0037] On the other hand, through the cooperation between the first support rod 12 and the second support rod 13, the posture of the stone rough material in the placing tube 1 can be adjusted, so that the weak interlayer in the stone rough material is adjusted to a horizontal state, which can facilitate the subsequent direct cutting of the upper and lower plate surfaces of the sample to form a finished sample.

[0038] Preferably, the first support rod 12 and the second support rod 13 are set as threaded rods, and matching threaded holes are opened on the bottom and side walls of the placement tube 1 to install the first support rod 12 and the second support rod 13. The length of the first support rod 12 and the second support rod 13 inserted into the placement tube 1 can be adjusted. When placing stone materials of different sizes, the length of the first support rod 12 and the second support rod 13 inserted into the placement tube 1 can be adjusted to more firmly fix the stone materials. At the same time, the placement tube 1 can be made of transparent material, which makes it easier for operators to observe the position of the stone materials in the placement tube 1. The stability of the device is further improved by providing the first support rod 12 and the second support rod 13.

[0039] In this embodiment, when the side wall of the container 1 is thin, a positioning ring 14 is installed horizontally around the outer side of the container 1, and the second support rod 13 is screwed to the positioning ring 14 and then penetrates the side wall of the container 1.

[0040] See also Figure 4 The sampling device includes a piston top rod 2, a pressure cylinder 3 and a pressure supply mechanism. The pressure cylinder 3 is installed at the bottom of the container 1. One end of the piston top rod 2 is slidingly and sealingly arranged in the pressure cylinder 3, and the other end is slidingly arranged in the mounting hole 11. The bottom of the pressure cylinder 3 is provided with a channel 31 connected to the pressure supply mechanism. The pressure supply mechanism provides pressure medium to the pressure cylinder 3 through the channel 31. The piston top rod 2 and the pressure cylinder 3 form a cylinder or oil cylinder structure. The pressure supply mechanism provides compressed air or hydraulic oil to drive the piston top rod 2 to extend. When the piston top rod 2 is extended, the top of the piston top rod 2 passes through the mounting hole 11, thereby being able to push the sample out of the container 1. When pouring glue, the top of the piston top rod 2 is flush with the inner wall of the container 1, so that the piston top rod 2 closes the mounting hole 11.

[0041] Of course, the sampling device can also be a bolt. When the glue is poured, the top of the bolt is flush with the inner wall of the container 1, so that the bolt closes the mounting hole 11. When the solidified sample needs to be ejected, the bolt is turned to eject the sample. In this solution, the top of the container 1 needs to have a certain thickness.

[0042] In a preferred embodiment, the pressure supply mechanism is an inflation mechanism 4. The inflation mechanism 4 includes a fixed plate 41, an inflation cylinder 42, a piston rod 43, a hinge seat 44, a pull rod 45, and an auxiliary rod 46. The inflation cylinder 42 is fixedly mounted on the fixed plate 41. One end of the piston rod 43 is slidingly and sealingly disposed within the inflation cylinder 42, and the other end is hinged to the hinge seat 44. The hinge seat 44 is mounted on the pull rod 45. One end of the auxiliary rod 46 is hinged to the fixed plate 41, and the other end is hinged to one end of the pull rod 45. The bottom of the inflation cylinder 42 is connected to the channel 31.

[0043] like Figure 5 As shown, the pressure cylinder 3 can also be set on the fixed plate 41, so that the inflation mechanism 4 and the pressure cylinder 3 form an integral structure. When it is necessary to inflate the pressure cylinder 3, the operator continuously bends the tail of the pull rod 45 to move up and down, so that the pull rod 45 rotates with the top of the piston rod 43 as the center, performs a lever movement, and pulls the piston rod 43 to perform reciprocating motion in the inflation cylinder 42. The reciprocating motion of the piston rod 43 will push the internal air to flow into the pressure cylinder 3 through the channel 31 to generate air pressure. This inflation mechanism 4 has a simple structure and is easy to operate. The operator only needs to operate the pull rod 45 up and down to complete the inflation of the pressure cylinder 3, thereby realizing the ejection of the piston push rod 2, further improving the operational convenience of the device. The structure of the inflation mechanism 4 is similar to that of an air pump.

[0044] Furthermore, a one-way valve 34 is provided in the channel 31 .

[0045] By setting a one-way valve 34, the air flow in the pressure cylinder 3 can be prevented from flowing back during the inflation process of the inflation mechanism, ensuring that the gas pressure acts on the piston push rod 2 in one direction, thereby reducing the time for the piston push rod 2 to be ejected, thereby increasing the sample preparation efficiency of the device.

[0046] Furthermore, it also includes an air hole plug 32 . The pressure cylinder 3 is provided with an air release hole 33 on one side near the bottom thereof. The air hole plug 32 is detachably mounted and connected to the air release hole 33 .

[0047] When the inflation mechanism 4 inflates the pressure cylinder 3, the vent plug 32 blocks the vent hole 33, maintaining a sealed environment in the middle and lower sections of the pressure cylinder 3. After the piston push rod 2 lifts and removes the sample, the pressure in the pressure cylinder 3 can be relieved through the vent hole 33, allowing the piston push rod 2 to return to its original position, making it easier to prepare the next sample. When preparing the next sample, the vent hole 33 is also blocked by the vent plug 32, maintaining a sealed environment in the middle and lower sections of the pressure cylinder 3, making it easier to prepare the subsequent sample. The provision of the vent plug 32 and the vent hole 33 improves the ease of operation of the device.

[0048] Optionally, the present invention also includes a shaking mechanism 5, which includes a support seat 51, a base 52, a spring 53, an eccentric wheel 54 and a driving device. The bottom of the container 1 is fixed on the support seat 51, and a slide groove is provided on the base 52. The support seat 51, the spring 53 and the eccentric wheel 54 are all arranged in the slide groove. The spring 53 and the eccentric wheel 54 are respectively arranged at both ends of the slide groove. The support seat 51 is arranged between the spring 53 and the eccentric wheel 54. The driving device is transmitted to the eccentric wheel 54 to drive the eccentric wheel 54 to rotate.

[0049] like Figure 6 As shown, the support base 51 includes a support plate 511 and support columns 512. Four support columns 512 are vertically arranged on the support plate 511, and the placement tube 1 is arranged on the four support columns 512. The wide side of the support plate 511 matches the width of the chute 521, so that the support plate 511 can be slidably arranged in the chute 521. One end of the spring 53 is connected to the groove wall at one end of the chute 521, and the other end of the spring 53 is connected to one end of the support plate 511. The other end of the support plate 511 is connected to the eccentric wheel 54. The eccentric wheel 54 is clamped between the groove wall at the other end of the chute and the other end of the support plate 511. The driving device is in transmission connection with the eccentric wheel 54. When the driving device controls the rotation of the eccentric wheel 54, the support plate 511 is pushed by the eccentric wheel 54 and the elastic force of the spring 53, and reciprocates along the chute, while causing the placement tube 1 fixed to the support column 512 to reciprocate. During the process of pouring glue, the driving device causes the container 1 to move back and forth, increasing the flow rate of the glue, while reducing the bubbles in the glue, improving the adhesion between the glue and the stone rough material, and preventing the generation of bubbles and bonding voids between the glue and the stone rough material, which causes the glue to be unable to fix the stone rough material, thereby improving the yield of sample preparation of this device.

[0050] Specifically, the driving device is a handle 55 or a motor.
