[0002] The soil sampling device for soil remediation is a professional equipment serving the field of soil remediation. It is mainly used to collect soil samples at different depths and in different areas. Its structure usually includes a sampling drill bit, a drill rod, a power system, a positioning device and other parts. The sampling device can be drilled into the soil layer to obtain samples through mechanical drilling, manual operation or hydraulic drive. Some devices are also equipped with GPS positioning function to accurately record the location of the sampling point. It can provide key data support for soil pollution status assessment, remediation plan formulation and remediation effect monitoring, ensuring that soil remediation work is carried out scientifically and effectively.

[0003] When sampling, it is often necessary to sample multiple locations in an area to obtain more comprehensive soil data.

[0034] like Figures 1 to 6 As shown, the present invention provides a soil sampling device for soil remediation, comprising a base 1 and further comprising:

[0035] The storage mechanism 2 is provided on the top outer wall of the base 1;

[0036] The driving module 5 is arranged on the top outer wall of the base 1, and a sampling tube 6 is provided on the outer wall of the driving module 5;

[0038] The stabilizing mechanism 4 is provided on the outer wall of the bottom end of the base 1;

[0039] The storage mechanism 2 includes a storage cylinder 201, and a placement cylinder 208 is provided on the inner wall of the storage cylinder 201;

[0040] The adjustment mechanism 3 includes a bracket 301, and an adjustment rod 303 is slidably connected to the inner wall of the bracket 301;

[0041] The stabilizing mechanism 4 includes a moving rod 402 , and a bottom plate 404 is fixedly connected to the outer wall of the bottom end of the moving rod 402 .

[0042] The above scheme is adopted: four sets of universal wheels are provided under the base 1, and the base 1 can be driven to move by pushing the handle 304 of the adjustment mechanism 3. The adjustment mechanism 3 can adjust the height of the handle 304 to adapt to operators of different heights. After the base 1 is moved to the sampling location, the stability of the sampling process can be improved by the stabilization mechanism 4 to avoid deviation or movement; the sampling tube 6 can be fixed to the driving module 5 by threads, and the driving module 5 is provided with a cylinder, which can enable the sampling tube 6 to be inserted into the soil for sampling, which is the existing technology; the sampling tube 6 can be stored in the storage mechanism 2, and multiple groups can be stored, and it is also convenient to take the sampling tube 6.

[0043] like Figures 3 and 4 As shown, a cover plate 202 is provided on the top outer wall of the storage cylinder 201, and the inner wall of the cover plate 202 is elastically connected to a square block 204 through an elastic member A203, and a guide block 215 is fixedly connected to the inner wall of the bottom end of the storage cylinder 201, and a pressure rod 205 is elastically connected to the inner wall of the bottom end of the storage cylinder 201 through a return spring 216, and the inner wall of the storage cylinder 201 is fixedly connected to a fixing ring 206, and the inner wall of the fixing ring 206 is rotatably connected to a rotating rod 209, and the outer wall of the rotating rod 209 is fixedly connected to a telescopic rod 211, and the outer wall of the pressure rod 205 is fixedly connected to a triangular block 214, and a square groove 210 is provided on the outer wall of the rotating rod 209, and the inner wall of the bottom end of the storage cylinder 201 is slidably connected to a push plate 212, and the outer wall of the push plate 212 is fixedly connected to a connecting rod 213, and the outer wall of the storage cylinder 201 is hinged with a baffle 207.

[0044] The above scheme is adopted: the cover 202 can be fixed to the top of the storage tube 201 by a lock, and a circular groove is provided on the outer wall of the cover 202, which is adapted to the rotating rod 209. After the cover 202 is closed, the rotating rod 209 and the pressure rod 205 both pass through its surface; a protrusion is provided on the surface of the square block 204, which passes through the top outer wall of the cover 202, and the rotating rod 209 can be limited by the engagement of the square block 204 with the square groove 210; multiple groups of placement tubes 208 can be provided, and the interior can be used to store sampling tubes 6. Each group of placement tubes 208 is fixed to the outer wall of the rotating rod 209 by a telescopic rod 211 and is located inside the storage tube 201. The baffle 207 can be flipped, and after it is opened, a group of placement tubes 208 can be pushed out of the interior of the storage tube 201, and the sampling tube 6 in the placement tube 208 can be taken out.

[0045] like Figures 3 and 4 As shown, one end of the elastic member A203 is fixedly connected to the outer wall of the square block 204, and the other end of the elastic member A203 is fixedly connected to the inner wall of the cover plate 202. The square block 204 is slidably connected in the inner wall of the cover plate 202, and the square block 204 is snap-fitted into the square groove 210.

[0046] The above solution is adopted: the fixing ring 206 is fixed in the inner wall of the storage cylinder 201 to provide support for the rotating rod 209, and the rotating rod 209 can rotate in the inner wall of the fixing ring 206; under normal conditions, the square block 204 is in a state of being engaged with the square groove 210 due to the elastic force of the elastic member A203, thereby fixing the rotating rod 209. The square groove 210 can also be provided with multiple groups, the number of which is the same as that of the storage cylinder 208, and the position thereof corresponds to that of the storage cylinder 208. When the top protrusion of the square block 204 is moved, The elastic part A203 will be squeezed and separated from the square groove 210. At this time, the rotating rod 209 can be rotated. During the rotation of the rotating rod 209, when the placement cylinder 208 moves to the position corresponding to the baffle 207, a group of square grooves 210 will also correspond to the position of the square block 204. At this time, the square block 204 is engaged with the square groove 210, so that the corresponding state of the placement cylinder 208 and the baffle 207 can be maintained, and in this state, the group of placement cylinders 208 will contact the outer wall of the push plate 212.

[0047] like Figures 3 and 4 As shown, the pressure rod 205 contacts the inner wall of the rotating rod 209, the guide block 215 is slidably connected to the inner wall of the bottom end of the pressure rod 205, one end of the return spring 216 is fixedly connected to the outer wall of the pressure rod 205, the other end of the return spring 216 is fixedly connected to the inner wall of the bottom end of the storage tube 201, the connecting rod 213 is slidably connected to the outer wall of the triangular block 214, the push plate 212 contacts the outer wall of the placement tube 208, and the placement tube 208 is fixedly connected to the movable end of the telescopic rod 211.

[0048] The above scheme is adopted: the guide block 215 is square and is inserted into the inner wall of the pressure rod 205, so that the pressure rod 205 can only move up and down, and the return spring 216 will be extended and retracted during the movement; under normal circumstances, the return spring 216 keeps the pressure rod 205 in a certain position. At this time, the pressure rod 205 and the triangular block 214 are both fixed, and the connecting rod 213 contacts the bottom end of the inclined surface of the triangular block 214; when the pressure rod 205 is pressed, the return spring 216 is compressed, and the pressure rod 205 and the triangular block 214 move downward synchronously. The inclined surface of the triangular block 214 squeezes the connecting rod 213 and drives the push plate 212 to move. Since the push plate 212 can only move laterally along the inner wall of the bottom end of the storage tube 201, the placement tube 208 in contact with it can be pushed outward by the push plate 212, and moved from the opened baffle 207 to the outside of the storage tube 201, the sampling tube 6 in the group of placement tubes 208 can be taken out.

[0049] like Figure 5 As shown, a groove 302 is formed on the inner wall of the bracket 301, a handle 304 is fixedly connected to the outer wall of the adjustment rod 303, a slide rod 305 is slidably connected to the inner wall of the adjustment rod 303, and a wedge block 307 is hinged to the outer wall of the slide rod 305 through a hinge rod 306.

[0050] The above scheme is adopted: multiple groups of grooves 302 are provided, which are vertically distributed in the inner wall of the bracket 301. The adjusting rod 303 can move up and down in the inner wall of the bracket 301 to adjust the combined height of it and the bracket 301, and then adjust the height of the handle 304, so that operators of different heights can hold the handle 304 more comfortably to push it; the outer wall of the slide rod 305 is provided with a shift block, which passes through the outer wall of the adjusting rod 303. Moving the shift block can drive the slide rod 305 to move downward; the hinged rod 306, the elastic part B308, and the wedge block 307 are each provided with two groups, which are symmetrically distributed in the inner walls on both sides of the adjusting rod 303.

[0051] like Figure 5 As shown, the bracket 301 is fixedly connected to the top outer wall of the base 1, the two ends of the hinged rod 306 are respectively hinged to the wedge block 307 and the bottom outer wall of the sliding rod 305, and the wedge block 307 is slidably connected to the inner wall of the adjusting rod 303; there are two groups of wedge blocks 307, and the two groups of wedge blocks 307 are elastically connected by an elastic member B308, and the two ends of the elastic member B308 are respectively fixedly connected to the outer walls of the two groups of wedge blocks 307.

[0052] When the adjusting rod 303 needs to be moved downward, the block on the outer wall of the slide bar 305 can be pushed upward to move the slide bar 305 upward, thereby driving the adjusting rod 303 to move upward. The top end of the rod 306 moves upward. Since the wedge block 307 can only move horizontally in the inner wall of the adjustment rod 303, the hinged rod 306 will flip and drive the wedge block 307 to move into the inner wall of the adjustment rod 303, breaking contact with the groove 302, and the limit of the adjustment rod 303 can be released to move it downward; when it moves to the appropriate position, the elastic member B308 will drive the wedge block 307 to pop out to both sides due to its own elastic force and insert it into the corresponding groove 302, completing the fixation of the adjustment rod 303 again, and then the height of the handle 304 can be adjusted without turning the bolt, which is more convenient and quick.

[0053] like Figure 2 、 Figure 6 As shown, the outer wall of the base 1 is fixedly connected to a fixed block 401, the moving rod 402 is elastically connected to the outer wall of the fixed block 401 through a telescopic spring 403, and the inner wall of the fixed block 401 is elastically connected to an insert block 406 through an elastic member C405.

[0054] The above-mentioned solution is adopted: the stabilizing mechanism 4 is arranged on both sides of the base 1, the bottom plate 404 is located below the base 1, and multiple groups of rubber blocks are provided at its bottom end. When the bottom plate 404 contacts the ground, the contact area with the ground can be increased, thereby improving stability, and the rubber blocks can increase the friction with the ground, so that the base 1 will not move during the soil sampling process; and when the base 1 is pushed, the bottom plate 404 is always not in contact with the ground, thereby not affecting its normal movement; there are two groups of empty grooves on the outer wall of the moving rod 402, which are vertically distributed on the outer wall of the moving rod 402. The empty grooves can be engaged with the plug blocks 406 to fix the position of the moving rod 402 and the bottom plate 404.

[0055] like Figure 2 、 Figure 6 As shown, the moving rod 402 is slidably connected to the inner wall of the fixed block 401, and the two ends of the telescopic spring 403 are fixedly connected to the outer walls of the fixed block 401 and the moving rod 402 respectively; one end of the elastic member C405 is fixedly connected to the outer wall of the plug block 406, and the other end of the elastic member C405 is fixedly connected to the inner wall of the fixed block 401, and the plug block 406 is slidably connected to the inner wall of the fixed block 401, and the plug block 406 is clamped in the empty groove on the outer wall of the moving rod 402.

[0056] The above solution is adopted: a pedal is provided at the top of the moving rod 402. When the operator needs to lower the bottom plate 404, he can press the pedal downward to drive the moving rod 402 and the bottom plate 404 to move downward synchronously. The telescopic spring 403 is stretched. During this process, the empty groove below the outer wall of the moving rod 402 squeezes the inclined surface of the insert block 406, causing it to compress the elastic member C405 and move it into the inner wall of the fixed block 401. When the bottom plate 404 moves to contact the ground, the empty groove above the outer wall of the moving rod 402 and the insert block 406 are pressed together. Corresponding to the position, the elastic member C405 inserts the insert block 406 into the empty slot due to its own elastic force, and the straight surface of the insert block 406 contacts the inner wall of the empty slot, so that the moving rod 402 will not move upward due to the elastic force of the telescopic spring 403, and the bottom plate 404 is kept in contact with the ground; and when the insert block 406 is pulled, the limit of the moving rod 402 can be released. At this time, the telescopic spring 403 will drive the moving rod 402 and the bottom plate 404 to move upward and reset due to its own elastic force. The bottom plate 404 is out of contact with the ground and the stabilizing mechanism 4 can be folded up.

[0057] The working principle and use process of the present invention:

[0058] The operator can first move the top protrusion of the square block 204, squeeze the elastic member A203 to disengage it from the square groove 210, remove the cover 202, place multiple sets of sampling tubes 6 in the placement tube 208, cover the cover 202, and then adjust the height of the handle 304 to a more comfortable position according to their own height; if downward adjustment is required, the operator can move the block of the sliding rod 305 on the outer wall of the adjustment rod 303 upward to move the sliding rod 305 upward, driving the wedge block 307 through the hinge rod 306. Move toward the inner wall of the adjusting rod 303 to release the limit of the adjusting rod 303 in the groove 302 on the inner wall of the bracket 301, and the adjusting rod 303 can be moved downward; if the handle 304 needs to be raised, the adjusting rod 303 can be pulled, and the inner wall of the groove 302 can squeeze the wedge block 307 to move the handle 304 upward; after the handle 304 is adjusted to the appropriate height, the elastic member B308 drives the wedge block 307 to pop out and insert it into the corresponding groove 302, fixing the position of the adjusting rod 303.

[0059] Push the handle 304 and use the four sets of universal wheels under the base 1 to move the device to the sampling location, then step on the pedal at the top of the moving rod 402 to drive the moving rod 402 and the bottom plate 404 to move downward synchronously, the telescopic spring 403 is stretched, and the empty groove below the outer wall of the moving rod 402 squeezes the insert 406; when the bottom plate 404 contacts the ground, the elastic part C405 pushes the insert 406 to insert into the empty groove above the outer wall of the moving rod 402, fixes the position of the moving rod 402, keeps the bottom plate 404 in contact with the ground, improves the sampling stability, and will not move and cause any impact during the sampling process.

[0060] Then open the baffle 207 and press the pressure rod 205 to compress the return spring 216. The pressure rod 205 and the triangular block 214 move downward synchronously. The inclined surface of the triangular block 214 squeezes the connecting rod 213, driving the push plate 212 to push the corresponding placement cylinder 208 out of the storage cylinder 201 from the baffle 207, and take out the sampling tube 6 in the placement cylinder 208. The return spring 216 drives the pressure rod 205 and the push plate 212 to reset; the taken out sampling tube 6 is fixed to the driving module 5 by thread, and the cylinder in the driving module 5 is started to insert the sampling tube 6 into the soil for sampling.

[0061] After sampling is completed for one group of sampling tubes, the soil inside the sampling tubes 6 can be taken out, the sampling tubes 6 can be placed back into the placement tube 208, the placement tube 208 can be pushed into the storage tube 201, and then the top protrusion of the square block 204 can be moved to release the limit of the rotating rod 209. The rotating rod 209 can be rotated to rotate the placement tube 208 corresponding to the other group of sampling tubes 6 to the position corresponding to the push plate 212. The above-mentioned operation of pressing the pressure rod 205 is repeated to take out the group of sampling tubes 6 and continue the sampling operation.

[0062] After the sampling is completed, the plug block 406 is pulled to release the limit of the moving rod 402, and the telescopic spring 403 drives the moving rod 402 and the bottom plate 404 to move upward and reset. The bottom plate 404 is out of contact with the ground, and the operator can push the base 1 to move to the next location.
