Description

Technical Field

[0001] The invention relates to the technical field of mineral geological exploration, and in particular to a layered and extended soil percolation sampling device. Background Art

[0002] During mineral exploration, especially the exploration of metal mines or certain rare metal mines, soil leachate sampling can help discover possible sources of pollution during mineral development. If there are potential pollution problems in the mining area (such as acid mine drainage), changes in the chemical composition of the leachate can reflect the source of the pollutants. Therefore, soil leachate sampling can play an important role in mineral geological exploration.

[0003] In the actual working process, although the existing soil leachate sampling equipment can be stably inserted into the soil to sample the leachate, it is not possible to perform stratified multi-point sampling at different depths and different points at the same depth. Therefore, in order to ensure the accuracy of the subsequent investigation and detection results, the staff needs to perform multiple operations to complete the multi-point stratified sampling work, which has low work efficiency and high labor intensity. If it is necessary to obtain leachate from deep soil, it is difficult to penetrate the sampling equipment to the target depth without drilling because the surface soil is relatively compact. In the actual working process, the existing soil leachate sampling equipment does not have an automatic drilling function. Therefore, the staff is required to carry additional drilling equipment to help the sampling equipment to drill holes in the soil, which has poor practicality. Therefore, it is necessary to provide a stratified and extended soil leachate sampling equipment to meet the needs of users. Summary of the invention

[0048] In this embodiment, a storage cylinder 811 is welded and fixed to the bottom end of the limit frame 803, and the diameter of the storage cylinder 811 is the same as the diameter of the rotating cylinder 706. A second through slot 812 is penetrated through the storage cylinder 811, and a rubber plate 813 is fixedly connected in the second through slot 812. A third servo motor 814 is welded and fixed to the top surface of the inner part of the storage cylinder 811, and a rotating plate 815 is welded and fixed on the output shaft of the third servo motor 814. A first guide slot 816 is penetrated through the rotating plate 815. A connecting plate 817 is welded and fixed in the storage cylinder 811, and a second guide slot 818 is penetrated through the connecting plate 817. The rubber plates 813 are symmetrically distributed inside the second through slot 812. On the upper and lower sides, the rubber plates 813 on both sides are in contact with each other, and four first guide grooves 816 and four second guide grooves 818 are provided. The four first guide grooves 816 are distributed at equal angles on the rotating plate 815, and the four second guide grooves 818 are distributed at equal angles on the connecting plate 817. The first guide groove 816 is inclined, and a guide plate 819 is slidingly connected in the second guide groove 818. A guide tube 820 is welded and fixed on the guide plate 819. Under the common guidance of each first guide groove 816 and the corresponding second guide groove 818, each guide tube 820 can be used to push each sampling frame 823 to move outward at the same time, thereby ensuring the convenience and efficiency of subsequent stratified extension sampling work.

[0049] In this embodiment, the guide tube 820 is limitedly slidably connected in the first guide groove 816, the top of the guide tube 820 is connected to a hose 821, the top of the hose 821 is fixedly connected to the bottom of the limit frame 803, the guide tube 820 is provided with a through hole 822, a sampling frame 823 is welded and fixed on the guide tube 820, a top block 824 is welded and fixed on the sampling frame 823, a second filter plate 825 is welded and fixed on the top of the sampling frame 823, a drain pipe 826 is connected to the bottom of the sampling frame 823, a solenoid valve is installed on the drain pipe 826, the second guide groove 818 corresponds to the guide tube 820 one by one through the guide plate 819, the top surface of the hose 821 is flush with the inner bottom surface of the limit frame 803, and the sampling frame 823 is welded and fixed to the top of the sampling frame 823. The frames 823 are evenly spaced on the guide tube 820, and the sampling frames 823 correspond one to one with the second through grooves 812. The length and width of the second through grooves 812 are respectively greater than the width and thickness of the sampling frames 823. By inserting the storage tube 811 into the sampling hole, the third servo motor 814 can be driven. At this time, under the common guidance of each first guide groove 816 and the corresponding second guide groove 818, each guide tube 820 can be used to push each sampling frame 823 to move outward at the same time, and can be stably extended and inserted into the soil. At this time, through the simultaneous operation of each sampling frame 823, multi-point sampling of soil leachate at different depths in the same area can be performed at the same time, effectively improving the working efficiency of the soil leachate sampling equipment.

[0050] It should be noted that the present invention is a layered extended soil leachate sampling device. First, the staff can push the soil leachate sampling device by holding the connecting rod 11 on the support rod 9. At this time, under the action of the universal wheels 10 at the bottom of each support rod 9, the device as a whole can be conveniently and stably moved to the sampling area. Then the staff only needs to rotate the threaded rod 13 on the second fixed plate 12. At this time, through the rotation of the threaded rod 13, the insertion rod 14 can be pushed to be stably inserted into the soil, so as to conveniently complete the positioning and fixing of the entire device, and ensure the stability and safety of the subsequent working state of the entire device. Similarly, after the device completes the work, it only needs to rotate the threaded rod 13 in the opposite direction to drive the insertion rod 14 to move out of the soil, and then the entire device can be conveniently moved in the future.

[0051] After the equipment is positioned and fixed in the sampling area as a whole, the first hydraulic rod 701 and the first servo motor 703 can be driven. Under the driving action of the first hydraulic rod 701, the protective frame 702 and the connecting frame 704 can be used to push the rotating cylinder 706 to move downward at a uniform speed. At the same time, under the driving action of the first servo motor 703, the sealing plate 705 can be driven to rotate stably at the bottom of the connecting frame 704 through the output shaft. Under the rotation action of the sealing plate 705, the rotating cylinder 706 and the rotating rod 713 can be driven to rotate synchronously, and each conveying cylinder 708 can be driven to perform a stable circular motion. During the rotation and downward movement of the rotating cylinder 706, the soil can be cut in an annular manner through each cutting protrusion 707 at the bottom, and the soil cut into the inside of the rotating cylinder 706 is further cut and dispersed by the cutting blade 714 under the rotation action of the rotating rod 713. At this time, the soil cut into the inside of the rotating cylinder 706 is in a dispersed state.

[0052] During the circular motion of each conveying cylinder 708, the spiral rod 709 can be driven to perform circular motion synchronously. At this time, the spiral rod 709 can drive the circular gear 711 at the top to perform circular motion in the internal gear 712. Under the meshing driving action of the circular gear 711 and the internal gear 712, the spiral rod 709 can be driven to automatically rotate inside the conveying cylinder 708 during the circular motion. Under the self-rotation action of each spiral rod 709, combined with the corresponding conveying cylinder 708, the soil dispersed in the rotating cylinder 706 can be spirally transported upward and discharged through the discharge pipe 710 at the bottom to avoid soil residue in the sampling hole, which affects the subsequent lowering and sampling work of the multi-point sampling assembly 8. After the drilling is completed, the first hydraulic rod 701 can be driven to drive the rotating cylinder 706 to move upward to reset and separate from the soil.

[0053] Then the staff only needs to pull out the clamping rod 6 on the first fixing plate 4 to make it move out of the clamping slot 3 on the turntable 2, and then the turntable 2 can rotate. By rotating the turntable 2 180°, the overall position exchange of the automatic punching assembly 7 and the multi-point sampling assembly 8 can be completed. At this time, the storage cylinder 811 is directly above the soil sampling hole, and then the second hydraulic rod 801 can be driven. The second hydraulic rod 801 can push the storage cylinder 811 downward to the soil sampling hole through the limit frame 803 on the first filter plate 802. After the storage cylinder 811 is inserted into the appropriate position, the third servo motor 814 in the storage cylinder 811 can be driven. At this time, the third servo motor 814 can drive the rotating plate 815 to rotate stably, and under the rotation of the rotating plate 815, the inclined first guide groove 816 can push the guide tube 820 to move smoothly in the opposite direction of the second guide groove 818 on the connecting plate 817, and under the limiting effect of the guide plate 819, the stability of the movement state of the guide tube 820 can be ensured. At this time, each guide tube 820 moves toward the inner side of the storage tube 811 at the same time, and then each sampling frame 823 on the guide tube 820 can be pushed to push away the rubber plate 813 on the second through groove 812, and pass through the second through groove 812 to be inserted into the soil;

[0054] After each sampling frame 823 is stably inserted into the soil, the second servo motor 804 on the limit frame 803 can be driven. At this time, the second servo motor 804 can drive the push plate 805 to rotate continuously through the output shaft. Under the continuous rotation of the push plate 805, combined with the elastic force of the connecting spring 806, the piston 807 can be driven to automatically and stably reciprocate up and down in the limit frame 803. When the piston 807 moves upward, under the action of air pressure, the baffle 810 can be pushed to be close to the piston 807, and the first through groove 808 can be automatically closed. Therefore, through the upward movement of the piston 807, the guide tube 820 can be evacuated through the limit frame 803 and the hose 821, and the guide tube 820 passes through the through hole 822. Air is pumped into the sampling frame 823. Under the negative pressure suction effect inside the sampling frame 823, the sampling efficiency of the soil leachate can be further improved through the second filter plate 825. When the piston 807 moves downward, under the action of air pressure, the baffle 810 on the limit plate 809 is pushed to automatically rotate upward through the first through groove 808, and the first through groove 808 is opened, which will not cause pressure inside the sampling frame 823, and thus will not affect the normal operation of the sampling frame 823. Under the continuous up and down reciprocating action of the piston 807, the working efficiency of the soil leachate sampling equipment can be effectively improved. At this time, through the simultaneous operation of each sampling frame 823, multi-point sampling of soil leachate at different depths in the same area can be performed at the same time.

[0055] After the sampling work is completed, the rotating plate 815 can be driven by the third servo motor 814 to rotate in the opposite direction, thereby driving each sampling frame 823 to move and reset, and store it in the storage cylinder 811, and then the storage cylinder 811 is driven by the second hydraulic rod 801 to move upward and reset. At this time, through the same operation as above, the position exchange of the multi-point sampling component 8 and the automatic punching component 7 is completed by rotating the turntable 2, and the rotating cylinder 706 is driven to insert into the sampling hole to avoid affecting the extension of the sampling frame 823; then the rotating plate 815 is driven by the third servo motor 814 to rotate forward and push each sampling frame 823 to extend. At this time, the staff can open the solenoid valve on the drainage pipe 826 at the bottom of each sampling frame 823 one by one, and use the storage bottle to store the leachate samples in each sampling frame 823 separately, and classify them for subsequent detection; after the unloading is completed, the first hydraulic rod 701 can be driven to drive the rotating cylinder 706 to move upward and reset, completing all sampling work.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
