Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, and more particularly to a separation device and a detection method for soil sampling detection. Background Art

[0002] In the field of environmental monitoring and geological exploration, soil sampling is faced with diverse application scenarios and strict technical requirements. There are significant differences in soil characteristics and research purposes in different regions, which requires flexible adjustment of the specifications of the sampling tubes during the sampling process. For example, when conducting surface soil pollution investigations, larger diameter sampling tubes may be required to obtain sufficient sample volume, while when conducting deep soil structure research, thinner sampling tubes are required to reach the required depth. At the same time, in order to accurately analyze the vertical distribution characteristics of the soil, the collected samples also need to be accurately stratified, which places higher requirements on the performance and ease of operation of the sampling equipment.

[0003] However, existing soil sampling equipment has defects in the replacement of sampling tubes. Most equipment needs to rely on external tools or special auxiliary equipment to complete the installation and removal of sampling tubes. This design seriously restricts the efficiency of field operations. Operators have to carry additional tools and equipment and spend a lot of time and physical effort on loading and unloading operations in harsh field environments. Especially in work scenarios where sampling tubes of different specifications need to be replaced frequently, the cumbersome disassembly and assembly process not only reduces work efficiency, but also increases the risk of equipment damage.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0022] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0023] See also Figures 1 to 4 A separation device for soil sampling and testing, comprising a cone barrel 11 and a transmission plate 12 coaxially arranged on the cone barrel 11, a fixing mechanism comprising a bottom plate 31 attached to the soil, a plurality of spacer bars 32 are installed at equal intervals on both sides of the bottom plate 31, a plurality of insertion blocks 33 are installed at the lower end of each spacer bar 32, the fixing mechanism also comprises a plurality of insertion rods 34 installed on the lower end surface of the bottom plate 31, at least three surrounding rods 35 are installed on the upper end surface of the bottom plate 31, and a shrinking head is installed at the lower end of the cone barrel 11 41, and a plurality of spiral strips 42 are installed on the side walls of the cone barrel 11 and the shrinking head 41, a plurality of cutting grooves 43 are opened at the lower end of the shrinking head 41, and a plurality of side grooves 44 are opened at equal intervals on the side wall of the cone barrel 11. When the soil excavation is completed, a dividing disk 45 is inserted into the cone barrel 11, and a push plate 46 is slidably connected in the side groove 44, and the push plate 46 abuts against the dividing disk 45. A lifting plate 47 is slidably installed on the plurality of surrounding rods 35, and a motor 48 is connected to the lifting plate 47, and the protruding end of the motor 48 is connected to the transmission disk 12.

[0024] When taking soil from the corresponding soil, first install the corresponding cone barrel 11 on the transmission plate 12, and complete the installation through the transmission rod 21 and the receiving sleeve 22. Figure 1 Then, the bottom plate 31 is placed on the corresponding soil, and the insertion rod 34 at the lower end of the bottom plate 31 is inserted into the soil to fix the bottom plate 31. Then, the insertion blocks 33 on the spacer bars 32 on both sides are fitted on the soil. At this time, the operator steps on the multiple spacer bars 32 on both sides with his feet. Since the soil is definitely not in an absolute plane, the multiple spacer bars 32 will be pressed on the soil under the action of the operator's own weight. Since the spacer bars 32 can be deformed, they can be deformed according to the shape of the soil, thereby ensuring the stability of use.

[0025] After the bottom plate is fixed, the operator holds the motor 48 to drive the cone barrel 11 and the shrink head 41 into the soil. Figure 2 Then the motor 48 is started to make the cutting groove 43 cut the soil, the soil inside the cone barrel 11 enters the cone barrel 11, and the soil outside is discharged to the outside with the rotation of the spiral strip 42, avoiding soil pollution. The rotation of the spiral strip 42 also applies a downward force to provide a certain squeezing force on the soil in the cone barrel 11, so that the soil is compacted, and then the sampling process is completed. Please refer to Figure 3 , because the transmission disc 12 is inserted into the cone barrel 11, the leakage of soil is avoided, and then the cone barrel 11 is pulled out, see Figure 2 , insert multiple dividing plates 45 into the side grooves 44 respectively, and then insert the dividing plates 45 into the cone barrel 11 through the pushing plate 46 to separate the soil, and then remove the cone barrel 11 and push the sample out of the cone barrel 11. The mutual separation is ensured by multiple dividing plates, ensuring the convenience of separation.

[0026] See also Figures 4 to 8The connecting mechanism includes at least three transmission rods 21 fixedly mounted on the upper end of the cone barrel 11, and a receiving sleeve 22 corresponding to the transmission rod 21 is installed on the transmission plate 12. When in a fixed state, the transmission rod 21 is inserted into the receiving sleeve 22, and a plurality of groups of two-by-two corresponding limit blocks 23 are installed on the side wall of the receiving sleeve 22. A telescopic frame 24 is slidably installed between each two limit blocks 23, and a positioning rod 25 is installed on the telescopic frame 24. The positioning rod 25 is inserted into the receiving sleeve 22, and the transmission rod 21 A positioning groove 26 is provided on the side wall of the telescopic frame 24, and the positioning rod 25 is inserted into the positioning groove 26. Round rods 27 are respectively installed at the upper and lower ends of the telescopic frame 24, and two expansion grooves 28 are correspondingly provided on the side wall of the transmission rod 21. When the positioning rod 25 is inserted into the positioning groove 26, the round rod 27 abuts against the expansion groove 28. The connecting mechanism also includes a tension spring 29 installed on the telescopic frame 24, and multiple tension springs 29 are respectively connected to the side walls of the receiving sleeve 22. The receiving sleeve 22 is coaxially slidably connected with a lifting spring 29. The lifting ring 210 has two fixing holes 211 on each telescopic frame 24. A plurality of fixing rods 212 corresponding to the fixing holes 211 are installed on the lifting ring 210, and the fixing rods 212 and the fixing holes 211 are coaxially arranged. A plurality of guide rods 213 are installed on the lifting ring 210 at equal intervals. A guide groove 214 corresponding to the guide rod 213 is opened on the side wall of the receiving sleeve 22. The guide rod 213 is slidably connected in the guide groove 214. The receiving sleeve 22 is threadedly connected with a A rotating disk 215 is coaxially mounted with a follower ring 216, a plurality of side blocks 217 are mounted at the lower end of the lifting ring 210, the plurality of side blocks 217 are respectively stuck in the follower ring 216, a lower pressure sleeve 218 is slidably connected to the receiving sleeve 22, a plurality of guide rods 213 are respectively connected to the lower pressure sleeve 218, an unfastening groove 219 is provided on the lower pressure sleeve 218, and a plurality of vertical grooves 220 are provided in the unfastening groove 219, and a top ball 221 is mounted on the telescopic frame 24.

[0027] When the transmission rod 21 and the receiving sleeve 22 need to be connected, first insert the transmission rod 21 into the receiving sleeve 22. Figure 5 First, the upper end of the transmission rod 21 contacts the round rod 27 at the lower end, and the round rod 27 will be pushed open at this time, so that the tension spring 29 is stretched, and then the entire telescopic frame 24 slides outward accordingly. When the first expansion slot 28 moves to the round rod 27 at the lower end, although this round rod 27 and the corresponding expansion slot 28 do not conflict, multiple positioning rods 25 are still attached to the side wall of the transmission rod 21, so the round rod 27 will not move. Then the lower end round rod 27 moves to the position of the positioning slot 26, and the positioning rod 25 moves to the position of the expansion slot 28, but the uppermost round rod 27 is against the side wall of the transmission rod 21, so it still cannot rebound, and then until multiple round rods 27 respectively contact the expansion slot 28, and the positioning rod 25 is inserted into the positioning slot 26, the fixing process is completed.

[0028] When the snap-in connection is complete and needs to be fixed, refer to Figure 4 and Figure 6 By rotating the rotating disk 215, since the rotating disk 215 and the receiving sleeve 22 are threadedly connected, and the side block 217 is slidably connected to the follower ring 216, the lifting ring 210 can be driven to move upward, and then the fixing rod 212 is inserted into the fixing hole 211. At this time, the telescopic frame 24 is locked, thereby ensuring the stable fixation of the positioning rod 25 and the positioning groove 26. The guide rod 213 and the guide groove 214 are slidably connected to play a guiding role, and when the guide rod 213 is connected to the lifting ring 210 and the lower pressure sleeve 218, when the fixing rod 212 is inserted into the fixing hole 211, the lower pressure sleeve 218 will move upward away from the top ball 221.

[0029] When you need to unlock, please refer to the figure Figure 6 At this time, the rotating disk 215 is rotated in the opposite direction to make the lifting ring 210 slide downward, and then the connection between the fixing rod 212 and the fixing hole 211 is released. Under the action of the guide rod 213, the groove 219 is synchronously released to abut against the top ball 221, and then the multiple top balls 221 are synchronously expanded outward, thereby releasing the connection between the positioning rod 25 and the positioning groove 26, thereby completing the release process.

[0030] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
