In the falling process, the soil random sample can be stacked into a cone under the action of the cross-shaped plate and is cut into four equal parts at the same time. And then the diagonal arc-shaped plate is rotated, so that the random soil sample at the quartering diagonal part falls down, and quartering treatment of the random soil sample is completed. By adopting the structural design, the sampling investigation and detection treatment efficiency of the soil random sample can be greatly improved.

Description

Technical Field

[0001] The present invention belongs to the technical field of mine soil sampling, and more particularly relates to a mine soil layered sampling device. Background Art

[0002] Mine soil sampling refers to the general term for the entire work of collecting certain samples from ore bodies, surrounding rocks, and mine products according to certain specification requirements, and then conducting chemical analysis, testing, or identification after processing. Usually, mine soil sampling needs to follow the principles of representativeness, typicality, and diversity, that is, randomly sampling at different depths in the mine to obtain random soil samples at different depths, so as to facilitate subsequent analysis, research, evaluation, monitoring, investigation, and utilization.

[0003] In related technologies, generally, the quartering method is used to process the random soil samples after sampling. The quartering method is to pile the random soil samples into a uniform conical shape and press it into a frustum of a cone, then cut the frustum of the cone into four equal parts and discard the samples on the diagonal sides. Finally, the remaining samples are the random soil samples with scientificity and representativeness.

[0004] However, in the actual processing process, the above-mentioned sampling process of the quartering method is usually manually completed. This method not only reduces the detection work efficiency of the random soil samples, but also greatly causes waste of labor costs. Summary of the Invention

Detailed implementation manners

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0019] As Figures 1-6 shown, the mine soil layered sampling device provided by the embodiment of the present invention includes a cylinder body 100, a sealing plate 200, a stirring mechanism, a cross-shaped plate 400, and a diagonal arc plate 500. Among them, the cylinder body 100 is a container for accommodating and processing random soil samples. At the same time, the cylinder body 100 is also one of the main structures of the sampling device. The top end of the cylinder body 100 has an upwardly opened opening 110, and through the opening 110, the randomly sampled soil samples can be placed into the cylinder body 100. Preferably, the cylinder body 100 can be cylindrical. The cylindrical cylinder body 100 has the advantages of uniform stress distribution and simple structure. Moreover, the cylindrical cylinder body 100 is relatively simple to manufacture, and its quality is also easy to guarantee.

[0020] A first layer plate 140 is also horizontally laid inside the cylinder body 100. The outer diameter and shape of the first layer plate 140 are adapted to the inner outer diameter and shape of the cylinder body 100. The first layer plate 140 is used to divide the inner space of the cylinder body 100. And, a first material dropping hole 141 is also provided in the first layer plate 140 along the thickness direction. The first material dropping hole 141 is located at the center position of the first layer plate 140. During actual use, the randomly sampled soil samples entering the inside of the cylinder body 100 can enter the space below the first layer plate 140 through the first material dropping hole 141.

[0021] Continuing as Figure 1 -As Figure 3 shown, the stirring mechanism is composed of a stirring shaft 300, stirring blades 310, a driving motor 320, and a lapping plate 330. Among them, the driving motor 320 is horizontally arranged at the opening 110 of the cylinder body 100 through the lapping plate 330. The length of the lapping plate 330 is greater than the outer diameter of the opening 110 of the cylinder body 100, and the width of the lapping plate 330 is less than the outer diameter of the opening 110 of the cylinder body 100. This makes the lapping plate 330 only able to partially block the opening 110 of the cylinder body 100. Preferably, vertical connecting plates 340 are fixedly arranged at the bottom surfaces of both ends in the length direction of the lapping plate 330, and the vertical connecting plates 340 are fixedly connected to the outer wall of the cylinder body 100 by means of bolts.

[0022] The driving motor 320 is vertically installed above the overlapping plate 330, and the driving shaft of the driving motor 320 penetrates through the overlapping plate 330 in the thickness direction. The driving shaft of the driving motor 320 is fixedly connected to the stirring shaft 300. A plurality of stirring blades 310 are fixedly arranged on the outer wall of the stirring shaft 300. The plurality of stirring blades 310 are evenly distributed along the axial direction and the circumferential direction of the stirring shaft 300 respectively. Moreover, the stirring shaft 300 and the stirring blades 310 are both located in the space above the first layer plate 140.

[0023] In this embodiment, the blocking plate 200 is inserted into the cylinder 100 along the horizontal direction. As Figure 3 shown, the blocking plate 200 can be a rectangular plate with a certain length. The blocking plate 200 penetrates through the outer wall of the cylinder 100 and extends into its interior. Moreover, the blocking plate 200 is located below the first layer plate 140. When the blocking plate 200 is inserted into the interior of the cylinder 100, it can close the first material dropping hole 141 of the first layer plate 140, thereby preventing the random soil sample from falling downward through the first material dropping hole 141.

[0024] Preferably, a rectangular hole 160 for cooperating with the blocking plate 200 is provided on the outer wall of the cylinder 100. The blocking plate 200 is slidably connected to the cylinder 100 through the rectangular hole 160. In addition, for the convenience of using the blocking plate 200, a handle 210 is fixedly arranged at the position of the blocking plate 200 outside the cylinder 100. By manipulating the handle 210, the movement of the blocking plate 200 relative to the cylinder 100 can be controlled, so that the staff can change the position of the blocking plate 200 according to the actual situation and needs.

[0025] In actual use, the blocking plate 200 is pre-inserted into the cylinder 100 to close the first material dropping hole 141 of the first layer plate 140. Then, the sampled random soil sample is poured into the interior of the cylinder 100 through the opening 110, and the driving motor 320 is started to drive the stirring shaft 300 and the stirring blades 310 to stir and mix the random soil sample. Through the stirring and mixing process, the random soil sample can be fully mixed, and its internal components can be evenly distributed, so as to obtain a random soil sample with uniformity and representativeness, thereby providing a reliable basis for subsequent detection and analysis.

[0026] Continue as Figures 2-6As shown in the figure, the cross-shaped plate 400 is a cross structure formed by the intersection of two plates. The cross-shaped plate 400 is located inside the cylinder 100, and the outer wall of the cross-shaped plate 400 is fixedly connected to the inside of the cylinder 100. A bottom plate is also provided at the bottom end of the cross-shaped plate 400. The cross-shaped plate 400 is located directly below the first layer of plate 140. That is to say, the center point of the cross-shaped plate 400 and the center point of the first blanking hole 141 are on the same straight line in the vertical direction. Therefore, the random soil samples falling downward through the first blanking hole 141 will accumulate in a conical shape at the bottom plate of the cross-shaped plate 400, and the cross-shaped plate 400 will also evenly divide the conical random soil samples into four equal parts.

[0027] In addition, arc-shaped notches 410 are provided at the bottom plates of two opposite corners of the cross-shaped plate 400, and the center position at the bottom end of the cross-shaped plate 400 is connected to the diagonal arc-shaped plate 500 through a rotating shaft. Therefore, by rotating the diagonal arc-shaped plate 500, it is possible to choose to block or dredge the arc-shaped notches 410 of the cross-shaped plate 400. A handle 510 is fixedly provided on the side wall of the diagonal arc-shaped plate 500. The handle 510 passes through the outer wall of the cylinder 100 and extends to the outside thereof. The handle 510 is rotatably connected to the cylinder 100. Preferably, an arc-shaped hole 170 adapted to the handle 510 is provided on the outer wall of the cylinder 100.

[0028] When the diagonal arc-shaped plate 500 blocks the arc-shaped notches 410 at the bottom end of the cross-shaped plate 400, the random soil samples falling to the bottom plate through the first blanking hole 141 can be evenly divided into four equal parts under the action of the cross-shaped plate 400. As the diagonal arc-shaped plate 500 rotates to a position coinciding with the bottom plate, the random soil samples at the arc-shaped notches 410 will fall downward, so as to achieve the purpose of selecting the samples on both sides of the diagonal in the simulated quartering method. Finally, the fallen random soil samples can be taken through the corresponding sampling ports.

[0029] In the mine soil layer sampling device provided in the embodiment of the present invention, after the sampled random soil samples are poured into the inside of the cylinder 100 from the opening 110, they will first be subjected to stirring and mixing treatment by the stirring mechanism so that the random soil samples can be fully mixed and the internal components are evenly distributed. Then, the blocking plate 200 is pulled outwards from the cylinder 100 so that the stirred and mixed random soil samples fall downward through the first blanking hole 141. During the falling process, the random soil samples will be accumulated in a conical shape under the action of the cross-shaped plate 400 and simultaneously cut into four equal parts. Then, the diagonal arc-shaped plate 500 is rotated to make the random soil samples at the diagonals of the four equal parts fall downward to complete the quartering process of the random soil samples. With the above structural design, the random soil samples can be quickly quartered, thus greatly improving the efficiency of sampling investigation and detection of the random soil samples.

[0030] In some embodiments, a second layer plate 150 is further disposed inside the cylinder body 100. As Figure 7 shown, the second layer plate 150 is located above the first layer plate 140. The second layer plate 150 is provided with a second blanking hole 151 along the thickness direction, and the second blanking hole 151 is located at the center of the second layer plate 150. Moreover, a groove 152 recessed toward the second blanking hole 151 is provided on the top surface of the second layer plate 150. The outer diameter of the second blanking hole 151 is smaller than the outer diameter of the first blanking hole 141. The plugging plate 200 is located between the first layer plate 140 and the second layer plate 150.

[0031] During actual use, the plugging plate 200 is used to plug the first blanking hole 141 and the second blanking hole 151. The random soil samples located in the groove 152 of the second layer plate 150 will be stirred and mixed under the action of the stirring shaft 300 and the stirring blades 310. When the stirring and mixing process is completed, after the staff pulls out the plugging plate 200 outside the cylinder body 100, the random soil samples located in the groove 152 will all slide toward the direction of the second blanking hole 151. Preferably, a special material can also be selected to prevent the random soil samples from adhering to the wall surface of the groove 152. In addition, the outer diameter of the second blanking hole 151 is smaller than the outer diameter of the first blanking hole 141, which can prevent the problem that the random soil samples accidentally spill on the surface of the first layer plate 140 during the falling process. By adopting the above structural design, the situation of resource waste during the quartering process of the random soil samples can be avoided.

[0032] In some embodiments, a conical dividing part 430 is further provided at the top end of the cross-shaped plate 400. As Figure 8 and Figure 9 shown, the tip of the conical dividing part 430 faces the direction of the first blanking hole 141. When the random soil samples fall downward through the first blanking hole 141, they will pass through the conical dividing part 430. The random soil samples passing through the conical dividing part 430 will spill in all directions, which helps the random soil samples to accumulate into a uniform cone or frustum shape, and at the same time can also make the cross-shaped plate 400 divide the random soil samples more evenly.

[0033] Preferably, an arc surface 420 can also be provided on the top surface of the cross-shaped plate 400, and the arc surface 420 is a structure extending downward. By adopting the structure of the arc surface 420, it can prevent the random soil samples from falling on the top surface of the cross-shaped plate 400, thereby effectively improving the utilization rate of the random soil samples.

[0034] In some embodiments, a second cross-shaped plate 440 and a third layer plate 180 are further provided inside the cylinder body 100. The second cross-shaped plate 440 has the same structure as the cross-shaped plate 400, and the third layer plate 180 has the same structure as the second layer plate 150. As Figure 7 shown, a second groove 182 recessed towards the center is provided on the top surface of the third layer plate 180. The third layer plate 180 is located below the diagonal arc-shaped plate 500, and the second cross-shaped plate 440 is located at the third blanking hole of the third layer plate 180. The second conical material distribution part 450 at the top end of the second cross-shaped plate 440 and the third blanking hole are in a vertically corresponding relationship. With the above structural design, the random soil samples can be further quartered, thereby further improving the representativeness and accuracy of the random soil samples.

[0035] In some embodiments, as Figure 10 shown, the cylinder body 100 includes a cylinder shell 120 and a base 130 provided below the cylinder shell 120. Specifically, the bottom end of the cylinder shell 120 has a plurality of plug-in plates 121, and the plurality of plug-in plates 121 are equidistantly distributed along the circumferential direction at the bottom end of the cylinder shell 120. Oppositely, a plug-in groove 131 adapted to the plug-in plate 121 is provided on the top surface of the base 130. During actual use, the plug-in plates 121 of the cylinder shell 120 can be inserted into the plug-in grooves 131 of the base 130, thereby splicing the two into a complete cylinder body 100. When it is necessary to perform detection processing on the quartered random soil samples, the cylinder shell 120 can be directly pulled upward.

[0036] In some embodiments, a double-layer sleeve 600 is further provided inside the cylinder body 100. As Figure 11 and Figure 12 shown, the double-layer sleeve 600 is composed of an inner cylinder 610, an outer cylinder 620, and a sleeve bottom plate 630 provided between the two. Among them, the outside of the outer cylinder 620 is sleeved at the opening 110 of the cylinder body 100 through a bending part. The inner cylinder 610 of the double-layer sleeve 600 is used to accommodate the stirring shaft 300 and the stirring blades 310, and the inner diameter of the inner cylinder 610 is larger than the size of the circle formed by the stirring blades 310. In addition, a plurality of sieve holes 631 are further provided along the thickness direction on the sleeve bottom plate 630 where the inner cylinder 610 is connected to the outer cylinder 620.

[0037] During actual use, the double-layer sleeve 600 can be sleeved at the opening 110 of the cylinder body 100 through the bending part in advance. After the stirring shaft 300 and the stirring blades 310 pass through the inner cylinder 610, the overlapping plate 330 can overlap on the cylinder body 100. Subsequently, the sampled random soil samples are poured onto the sleeve bottom plate 630. Therefore, impurities doped in the random soil samples can be screened through the sieve holes 631, thereby improving the final detection accuracy.

[0038] Preferably, as Figure 13 shown, the double-layer sleeve 600 can also be divided into the structure of an upper sleeve 700 and a lower sleeve 800. The upper sleeve 700 and the lower sleeve 800 are connected by a damping spring 900. A downwardly inclined annular inclined surface 710 is provided at the bottom end of the inner wall of the upper sleeve 700. Through the inclined surface 710, the random soil samples can slide down to the sleeve bottom plate 630. Moreover, during the sliding process of the random soil samples, the lower sleeve 800 will be continuously pressed downward, so that the damping spring 900 is stretched and contracted, and finally the function of vibration screening is realized.
