DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0029] The layered sampling equipment for detecting salt content of saline soil disclosed by the present application is mainly applied to the scene of layered sampling of saline land.

[0030] Reference Figures 1 to 11The application discloses a layered sampling device for detecting salt content of saline soil, which comprises a puller 1, a clamping device 2 is arranged at the bottom of the puller 1, a sampling mechanism 3 for sampling salt soil is clamped in the clamping device 2, the sampling mechanism 3 comprises a sampler 301 vertically inserted into a salt soil layer, a plurality of uniform distributed empty intervals 302 are formed in the side wall of the sampler 301, and one elastic cutter 303 is rotatably arranged in each empty interval 302. The sampling mechanism 3 is internally provided with a storage mechanism 4 for storing salt soil, the storage mechanism 4 comprises a plurality of storage tubes 401 which are mutually abutted and slidingly arranged in the inside of the sampler 301, and the storage tube 401 is of a single-end through hole structure. The sampling mechanism 3 is punched into the salt soil layer of a specified depth by using a pile driver, the salt layer of the side wall of the hole drilled by the sampling mechanism 3 is sampled and stored in the inside of the storage mechanism 4.

[0031] In the embodiment, a worker installs the sampling mechanism 3 to the bottom of a punch, starts an external punch, and presses the whole sampling mechanism 3 into saline soil to be inspected, so that the top of the sampling mechanism 3 is exposed above the ground surface. After the punch is started, the worker holds an electric screwdriver, abuts the electric screwdriver with the top of the sampling mechanism 3, controls the electric screwdriver to drive the sampling mechanism 3 to deform, and cuts into the saline soil of the side wall of the hole in a horizontal rotating mode. At this time, the worker moves the puller 1 to the top of the sampling mechanism 3, clamps the clamping device 2 on the top of the sampling mechanism 3 and pulls it upward at a small amplitude. In this process, the sampling mechanism 3 digs the salt soil of the side wall of the hole into the inside of the storage mechanism 4. After that, the worker controls the electric screwdriver to reset the deformation of the sampling mechanism 3, and pulls out the sampling mechanism 3 from the soil by using the puller 1. After being pulled out, the worker can separately draw out the storage mechanism 4 from the sampling mechanism 3, and the sampling work is completed.

[0032] Reference Figures 1 to 7 , Figure 9 In a preferred embodiment, a reinforcing member 305 is arranged in the inside of the sampler 301 and fixedly connected with the plurality of elastic cutters 303, the reinforcing member 304 is fixedly connected with the elastic cutter 303, a threaded tube 306 is fixed at the top of each empty interval 302, the threaded tube 306 is hollow, the reinforcing member 305 penetrates through the threaded tube 306, the top of the reinforcing member 304 is provided with a top sleeve 3041, the inner surface of the top sleeve 3041 is threadedly connected with the outer surface of the threaded tube 306, and the top sleeve 3041 is slidingly connected with the reinforcing member 305.

[0033] The worker installs the sampling mechanism 3 to the bottom of the punch press, starts the external punch press, and presses the whole sampler 301 into the saline soil to be inspected, ensuring that the top of the sampler 301 is exposed above the ground surface. After completing the pressing of the sampler 301, the worker holds the electric screwdriver and abuts the top of the reinforcing member 305 with the electric screwdriver, and controls the electric screwdriver to drive the reinforcing member 305 to rotate by 180°. The rotating reinforcing member 305 drives the plurality of reinforcing members 304 and the elastic cutter 303 to rotate outward along the inside of the empty interval 302, thereby cutting into the saline soil of the borehole sidewall. The specific state is shown in FIGS. 8 and 9. Figure 7 and Figure 8 At this time, the worker moves the extractor 1 to the top of the sampler 301, and clamps the clamping device 2 to the top of the sampler 301 and pulls it slightly upward. In this process, the elastic cutter 303 digs the saline soil of the borehole sidewall into the inside of the storage mechanism 4.

[0034] During the rotation of the reinforcing member 305 and the elastic cutter 303, the reinforcing member 304 and the top sleeve 3041 at the top also rotate. The top sleeve 3041 is driven by the threaded tube 306, thereby moving downward synchronously. The downward moving top sleeve 3041 pushes the reinforcing member 304 to bend, and makes the elastic cutter 303 expand outward. The gap between the expanded elastic cutter 303 and the empty interval 302 increases, thereby increasing the amount of soil entering.

[0035] Each elastic cutter 303 has a guide channel 3031 in the middle, which guides the movement of the cut saline soil. Specifically, the top sleeve 3041 is slidingly connected in the annular groove 5 at the top of the empty interval 302. The vertically moving reinforcing member 304 synchronously drives the top sleeve 3041 to slide vertically along the inside of the annular groove 5, thereby ensuring the sealing of the position of the threaded tube 306, and avoiding the influence of impurities on the driving effect of the threaded groove.

[0036] It is worth noting that the elastic cutter 303 and the reinforcing member 304 of the present application are made of elastic steel, alloy or other materials. The edge of the elastic cutter 303 is chamfered, so that the edge is sharp, thereby reducing the resistance when cutting into the soil. The surface of the reinforcing member 304 can also be chamfered, thereby reducing the resistance of the soil entering the guide channel 3031.

[0037] Specifically, the top of the reinforcing member 305 is welded and fixed with a quick connection sleeve head 3053, the quick connection sleeve head 3053 and the electric screwdriver held by the worker are connected, thereby driving the reinforcing member 305 to rotate, and the top outer side of the reinforcing member 305 is fixed with a positioning clamping block 3051, and the top of the sampler 301 is fixed with a positioning clamping plate 3052, the positioning clamping block 3051 and the positioning clamping plate 3052 are symmetrically distributed, the positioning clamping block 3051 and the positioning clamping plate 3052 after rotation are in extrusion contact, so that the elastic cutter 303 is rotated by 180°, thereby ensuring the effect of cutting into the soil, even if the electric screwdriver is rotated more than 180°, the positioning clamping block 3051 and the positioning clamping plate 3052 will prevent the reinforcing member 305 from continuing to rotate, and the electric screwdriver itself has a torque adjustment function, when the reinforcing member 305 cannot continue to rotate, the electric screwdriver will automatically slip.

[0038] With reference to Figures 2 to 4 , Figure 6 , Figure 8 In a preferred embodiment, the side wall of the storage tube 401 is provided with a feeding cavity 402, the bottom of each empty interval 302 is provided with a feeding channel 403, and the bottom end of each feeding channel 403 is correspondingly distributed on the side of one feeding cavity 402.

[0039] The rotating elastic cutter 303 will expand outward, and as the sampler 301 moves vertically upward, the saline soil cut by the elastic cutter 303 will enter the inside of the storage tube 401 along the elastic cutter 303, the feeding channel 403 and the feeding cavity 402, then the worker pulls out the sampler 301 from the soil by the extractor 1, and after pulling out, the storage tube 401 is separately pulled out from the sampler 301, thereby completing the sampling work.

[0040] The top of the sampler 301 is screwed and installed with a quick connection sleeve rod 404, the quick connection sleeve rod 404 is blocked on the top of the storage tube 401 close to the quick connection sleeve head 3053, when stamping the sampler 301, the worker rotates and installs the quick connection sleeve rod 404 on the top of the sampler 301, and then quickly connects the top of the quick connection sleeve rod 404 and the stamper.

[0041] Further, the top of each storage tube 401 is provided with a threaded end 405, and a plurality of storage tubes 401 are threadedly connected with each other through the threaded ends 405, each storage tube 401 is separately taken down by rotating the storage tube 401 to make the threaded end 405 disengage.

[0042] With reference to Figure 1 and Figure 10In a preferred embodiment, the clamping device 2 comprises two clamps 201 connected to the end of the puller 1 by a steel cable traction, and each of the two clamps 201 is symmetrically provided with an annular clamping groove 202 at the proximal end, the two ends of the annular clamping groove 202 are different in size and the small end faces upward, the proximal end of the two clamps 201 is rotatably connected with a first type of adapter 203, and the proximal end of the two clamps 201 is also rotatably connected with a second type of adapter 204, and the second type of adapter 204 is clamped and sleeved on the outside of the sampler 301.

[0043] When the worker pulls out the sampler 301 inserted into the ground, the worker first sleeves the two clamps 201 and the first type of adapter 203 and the second type of adapter 204 on the outside of the sampler 301, and lets the small end of the annular clamping groove 202 face upward, then presses one end of the puller 1 with the hand, so that the other end connected to the clamping device 2 is raised upward, and the clamps 201 are pulled up at the same time, so that the clamps 201 rotate around the first type of adapter 203 and the second type of adapter 204, and are clamped on the outside of the sampler 301 through the annular clamping groove 202, and the sampler 301 is pulled up at the same time.

[0044] The workflow of the present application is as follows: First, the worker rotates the quick connection sleeve rod 404 and installs it on the top of the sampler 301, then quickly connects the top of the quick connection sleeve rod 404 with the punch, and then starts the external punch (not shown in the figure), and vibrates and covers the entire sampler 301 into the saline soil to be inspected, and the sampler 301 needs to be perpendicular to the ground during the covering process, and after the covering is completed, the top of the sampler 301 needs to be exposed above the ground surface, after the punch of the sampler 301 is completed, the worker holds the electric screwdriver, and the quick connection sleeve head 3053 at the top of the reinforcing member 305 is connected with the worker's handheld electric screwdriver, and the electric screwdriver is controlled to drive the reinforcing member 305 to rotate 180°, and the rotating reinforcing member 305 drives the several reinforcing members 304 and the elastic cutter 303 to rotate outward along the inside of the empty space 302, in this process, the top sleeve 3041 at the top of the reinforcing member 304 is driven by the threads of the threaded pipe 306, so as to move downward synchronously, and the moving top sleeve 3041 pushes the elastic cutter 303 to expand outward through the reinforcing member 304, so as to cut into the saline soil of the drilling sidewall in a horizontal rotation and expansion manner, and the specific state is shown in the attached Figure 7At this time, the worker moves the puller 1 to the top of the sampler 301, and clamps the clamping device 2 to the top of the sampler 301 and pulls it slightly upward, as the sampler 301 moves vertically upward, the saline soil cut by the elastic cutter 303 will enter the inside of the storage tube 401 along the elastic cutter 303, the feeding channel 403 and the feeding cavity 402, then the worker reverses the steel member 305 by 180° by using the electric screwdriver, so that the elastic cutter 303 resets and seals the feeding channel 403, after that, the worker pulls out the sampler 301 from the soil by the puller 1, and then separately pulls out the storage tube 401 from the sampler 301, and sequentially rotates and dismounts the storage tubes 401 filled with different depths, and the sampling work is completed.
