[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown, the present invention provides a sampling device for highway engineering, including a support 100, and further including: a movable plate 600, the movable plate 600 being disposed on the outer wall of the support 100 via a drive module 500, a movable cone 800 being fixedly connected to the outer wall of the movable plate 600, and a sampling tube 700 being disposed on the inner wall of the movable cone 800 via a fixing mechanism 300; an adjustment mechanism 200, the adjustment mechanism 200 being disposed on the outer wall of the movable cone 800; and a storage mechanism 400, the storage mechanism 400 being disposed on the top outer wall of the support 100. The adjusting mechanism 200 includes a rotating block 201, a lever 203 elastically connected to the outer wall of the rotating block 201 via a connecting spring 202, a plug rod 204 fixedly connected to the outer wall of the rotating block 201, a moving rod 206 fixedly connected to the outer wall of the rotating block 201, and a connecting block 210 fixedly connected to the outer wall of the moving rod 206.

[0020] The above scheme employs the following: the support 100 serves as the base of the sampling device, with casters installed underneath for movement on the road; the drive module 500 is existing technology, capable of driving the moving plate 600 up and down via a motor and threaded rod or a cylinder, thereby moving the moving cone 800 downwards into the soil, allowing sampling of the soil through the sampling tube 700; the sampling tube 700 has two sets, upper and lower, with staggered openings, allowing sampling at different depths in the soil; the rotating block 201 and the lever block 203 can rotate synchronously, and the moving rod 206 is slidably connected to the inner wall of the lever block 203, but the moving rod 206 can also rotate within the inner wall of the moving cone 800 and move up and down.

[0021] like Figures 2 to 5 As shown, the outer wall of the insertion rod 204 has a groove 205, the top outer wall of the sampling tube 700 has a connecting groove 209, and the inner wall of the toggle block 203 is elastically connected to the protrusion 208 by a reset spring 207.

[0022] Using the above scheme: the moving rod 206 can be moved down so that the insertion rod 204 can be inserted into the circular groove of the lever 203, and the moving rod 206 can be limited by the engagement of the groove 205 and the protrusion 208; the connecting groove 209 has the top outer wall of the upper set of sampling tubes 700, the connecting groove 209 is adapted to the connecting block 210, and after the moving rod 206 is pressed down, the connecting block 210 can be inserted into the connecting groove 209. At this time, the rotation of the moving rod 206 can drive the sampling tubes 700 to rotate synchronously.

[0023] like Figures 2 to 5 As shown, the toggle block 203 is rotatably connected to the outer wall of the top of the movable cone 800, the two ends of the connecting spring 202 are fixedly connected to the outer walls of the toggle block 203 and the rotating block 201 respectively, the moving rod 206 is in contact with the inner wall of the movable cone 800, and the connecting block 210 is engaged with the connecting groove 209.

[0024] Using the above scheme: In the initial state, the openings of both sampling tubes 700 face the inner wall of the moving cone 800 and are in a closed state. When the moving cone 800 is inserted into the soil to a suitable depth, the sampling tubes 700 can be rotated at a certain angle by the adjustment mechanism 200. The opening of the lower sampling tube 700 opens first for sampling, while the opening of the upper sampling tube 700 remains aligned with the inner wall of the moving cone 800. When it is necessary to sample soil at different depths, the sampling tubes 700 can be rotated again by the adjustment mechanism 200. The opening of the upper sampling tube 700 aligns with one side of the soil, while the lower sampling tube 700 is closed to the inner wall of the moving cone 800. This allows the two sets of sampling tubes 700 to perform segmented sampling and can accurately sample soil at the required depth without being affected by soil at other depths.

[0025] like Figures 2 to 5As shown, one end of the return spring 207 is fixedly connected to the outer wall of the protrusion 208, and the other end of the return spring 207 is fixedly connected to the inner wall of the toggle block 203. The protrusion 208 is slidably connected in the inner wall of the toggle block 203, and the protrusion 208 is engaged with the groove 205.

[0026] Using the above scheme: When the rotating block 201 and the moving rod 206 move down synchronously, the connecting spring 202 contracts under force, the insert rod 204 inserts into the inside of the lever block 203, and squeezes the inclined surface at the top of the protrusion 208 to move it into the inner wall of the lever block 203, compressing the return spring 207. When the moving rod 206 moves down to the point where the connecting block 210 is inserted into the connecting groove 209, the groove 205 corresponds to the protrusion 208, and the return spring 207 will drive the protrusion 208 to pop out and insert into the groove 205. The lever block 203, the insert rod 204, the rotating block 201, and the moving rod 206 are fixed together. After the protrusion 208 is pulled outward to disengage from the groove 205, the elastic force of the connecting spring 202 causes the rotating block 201 and the moving rod 206 to move up and reset, and the connecting block 210 disengages from the connecting groove 209.

[0027] like Figure 6 As shown, the fixing mechanism 300 includes a limiting block 301. A rotating rod 302 is rotatably connected to the inner wall of the limiting block 301. An insert block 304 is hinged to the outer wall of the rotating rod 302 via a hinge rod 303. The insert block 304 is elastically connected to the inner wall of the limiting block 301 via a telescopic spring 305. A slot 306 is provided on the inner wall of the moving cone 800.

[0028] Using the above solution: the limiting block 301 can be locked in the inner wall of the moving cone 800 or removed. The sampling tube 700 can be fixed inside the moving cone 800 by the limiting block 301, and the limiting block 301 is in contact with the outer wall of the sampling tube 700. The rotating rod 302 passes through one side of the outer wall of the limiting block 301. The operator can manually rotate the rotating rod 302, and the insert block 304 can be moved through the hinge rod 303 to release the limiting block 301 and remove it from the moving cone 800, so that the sampling tube 700 can be taken out.

[0029] like Figure 6 As shown, the limiting block 301 contacts the inner wall of the moving cone 800, the two ends of the hinge rod 303 are respectively hinged to the outer walls of the insert block 304 and the rotating rod 302, one end of the telescopic spring 305 is fixedly connected to the inner wall of the limiting block 301, and the other end of the telescopic spring 305 is fixedly connected to the outer wall of the insert block 304. The insert block 304 is slidably connected in the inner wall of the limiting block 301, and the insert block 304 is engaged with the slot 306.

[0030] Using the above solution: One end of the insert block 304 is set as a slope. When the limiting block 301 is inserted into the moving cone 800, the slope will be squeezed by the outer wall of the moving cone 800, causing the insert block 304 to move into the inner wall of the limiting block 301, compressing the telescopic spring 305. When the limiting block 301 moves to the position where the insert block 304 corresponds to the slot 306, the insert block 304 will pop out under the elastic force of the telescopic spring 305 and lock into the slot 306, preventing the limiting block 301 from moving outward. The sampling tube 700 is fixed. When the rotating rod 302 rotates, it will drive one end of the hinge rod 303 to move along the circumference, and the other end will drive the insertion block 304 to move. Since the insertion block 304 can only move laterally, the hinge rod 303 will flip and the insertion block 304 will move into the inner wall of the limiting block 301. Once it disengages from the slot 306, the limiting block 301 can be removed. The method of disassembling and installing the sampling tube 700 is more convenient and faster, and does not require connection and installation with bolts, etc., which is more efficient.

[0031] like Figures 7 to 9 As shown, the storage mechanism 400 includes a storage cylinder 401. A baffle 402 is hinged to the outer wall of the storage cylinder 401. A control rod 403 is rotatably connected to the inner wall of the storage cylinder 401. A storage block 410 is provided on the outer wall of the control rod 403 via a telescopic rod 411. A pressure rod 404 is elastically connected to the inner wall of the bottom end of the storage cylinder 401 via a compression spring 406. A triangular block 405 is fixedly connected to the outer wall of the pressure rod 404. A guide block 407 is fixedly connected to the inner wall of the bottom end of the storage cylinder 401. A short rod 408 is slidably connected to the outer wall of the triangular block 405. A push plate 409 is fixedly connected to the outer wall of the short rod 408. A square block 413 is elastically connected to the inner wall of the pressure rod 404 via a limiting spring 412. An arc-shaped plate 414 is slidably connected to the inner wall of the control rod 403.

[0032] The above scheme is adopted: the storage cylinder 401 is provided with multiple sets of storage blocks 410, and each set of storage blocks 410 can hold sampling tubes 700. Thus, multiple sets of sampling tubes 700 can be stored in the storage cylinder 401 in a unified manner, which is more convenient when carrying the sampling tubes 700, as there is no need to place the sampling tubes 700 in a separate place for carrying. It is also more convenient to take out or put in the sampling tubes 700. After opening the baffle 402, the pressure rod 404 can be pressed to push out a set of storage blocks 410 for storing or taking out the sampling tubes 700. Rotating the control rod 403 can switch the position of the multiple sets of storage blocks 410 to correspond to the position of the baffle 402.

[0033] like Figures 7 to 9 As shown, the storage cylinder 401 is fixedly connected to the outer wall of the support 100, one end of the compression spring 406 is fixedly connected to the outer wall of the bottom end of the pressure rod 404, the other end of the compression spring 406 is fixedly connected to the inner wall of the bottom end of the storage cylinder 401, the pressure rod 404 is in contact with the inner wall of the control rod 403, and the guide block 407 is slidably connected to the inner wall of the bottom end of the pressure rod 404.

[0034] The above scheme is adopted as follows: Under normal conditions, the compression spring 406 keeps the pressure rod 404 in a certain position due to its elastic force, so that the bottom end of the inclined surface of the triangular block 405 contacts the short rod 408; when the pressure rod 404 is pressed down, the compression spring 406 will be compressed by force, and when the pressure is lost, the compression spring 406 will drive the pressure rod 404 to return to its original position due to its elastic force; the guide block 407 is square, and the pressure rod 404 can only move vertically and cannot rotate under the action of the guide block 407. Since the control rod 403 can rotate, the guide block 407 can keep the pressure rod 404 in a fixed state when the control rod 403 rotates; when the pressure rod 404 moves down, it will drive the triangular block 405 to move synchronously, and push the short rod 408 to move to contact the top end of the inclined surface of the triangular block 405. Since the short rod 408 is fixed to the push plate 409 and the push plate 409 can only move laterally, it will push the push plate 409 to move outward.

[0035] like Figures 7 to 9 As shown, the telescopic rod 411 is fixedly connected to the outer wall of the control rod 403, the movable end of the telescopic rod 411 is fixedly connected to the outer wall of the storage block 410, and the push plate 409 is slidably connected to the inner wall of the bottom end of the storage cylinder 401.

[0036] The above scheme is adopted: multiple sets of telescopic rods 411 are provided, which can guide the storage block 410 and keep the storage block 410 in a lateral movement state when moving; the position of the push plate 409 corresponds to the baffle 402. When the baffle 402 is opened, when a set of storage blocks 410 corresponds to the position of the push plate 409, the pressing rod 404 can drive the push plate 409 to move outward, pushing the storage block 410 to move outward from the baffle 402, so that the sampling tube 700 can be placed or taken out; when the control rod 403 is rotated, different storage blocks 410 can be switched to correspond to the position of the push plate 409.

[0037] like Figures 7 to 9 As shown, one end of the limiting spring 412 is fixedly connected to the inner wall of the pressure rod 404, and the other end of the limiting spring 412 is fixedly connected to the outer wall of the square block 413. The square block 413 is in contact with the outer wall of the arc plate 414, and the square block 413 is slidably connected in the inner wall of the pressure rod 404.

[0038] Using the above solution: During the movement of the support 100, in order to prevent the multiple storage blocks 410 and their internal sampling tubes 700 from rotating synchronously due to the rotation of the control rod 403, the square block 413 can be engaged with the inner wall slot of the control rod 403 to limit the control rod 403 and the pressure rod 404, so that the control rod 403 cannot rotate; the arc plate 414 slides in the inner wall slot of the control rod 403 and will not detach from the slot. The operator can press the arc plate 414 inward to squeeze the square block 413 into the inner wall of the pressure rod 404, compress the limiting spring 412, and thus make the square block 413 disengage from the slot, allowing the control rod 403 to rotate.

[0039] Working principle and usage process of this invention: Operators can use the casters under the support 100 to push the device to the sampling area of ​​the highway project, or transport it to the sampling area. Ensure that the moving cone 800 is aligned with the target sampling point, and drive the moving cone 800 downward through the drive module 500. Use the conical closed end under the moving cone 800 to cut into the soil until the preset sampling depth is reached. At this time, the openings of the sampling tubes 700 inside the moving cone 800 correspond to the inner wall of the moving cone 800 and are in a closed state.

[0040] The operator can press down the moving rod 206, the connecting spring 202 retracts, the insert rod 204 is inserted into the lever 203, and the protrusion 208 is engaged in the groove 205, thus fixing the moving rod 206 and the lever 203. At this time, the connecting block 210 at the bottom of the moving rod 206 is inserted into the connecting groove 209. Then, the rotating block 201 is rotated, and the sampling tube 700 is rotated at a certain angle through the engagement of the connecting block 210 and the connecting groove 209, so that the opening of the lower set of sampling tubes 700 turns towards the soil side. Under the action of lateral pressure, the soil enters the lower sampling tube 700 from the opening.

[0041] After the lower sampling tube 700 completes sampling, the rotating block 201 can be rotated in the opposite direction to drive the sampling tube 700 back to the initial position with the opening closed. Then, the driving module 500 moves the upper sampling tube 700 to the next sampling depth. Repeat the above steps, rotate the moving rod 206 to rotate the upper sampling tube 700 so that the opening faces the soil. After collecting soil at the corresponding depth, the driving module 500 can be used to remove the moving cone 800 from the soil to complete the precise sampling at different depths.

[0042] When it is necessary to remove the sampling tube 700, the operator can first pull the protrusion 208, so that the moving rod 206 moves upward and resets due to the elastic force of the connecting spring 202, and the connecting block 210 disengages from the connecting groove 209. Then, rotate the rotating rod 302, and pull the insert block 304 out of the slot 306 through the hinge rod 303. The sampling tube 700 can be removed from the moving cone 800 by pulling out the limiting block 301.

[0043] Next, open the baffle 402, press the arc plate 414 to squeeze the square block 413, so that the square block 413 is disengaged from the empty slot on the inner wall of the control rod 403, and rotate the control rod 403. The telescopic rod 411 drives the storage block 410 to rotate, so that a set of empty storage blocks 410 are aligned with the position of the push plate 409. Press down the pressure rod 404, the triangular block 405 pushes the short rod 408 to drive the push plate 409 to move outward, push the aligned storage block 410 out of the storage cylinder 401, put the disassembled sampling tube 700 into the slot of the storage block 410, release the pressure rod 404, the compression spring 406 resets and drives the pressure rod 404 to retract, and then manually push the storage block 410 into the storage cylinder 401. Then close the baffle 402 to complete the storage of the sampling tube 700.
