Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, and specifically to a soil environment detection sampling device. Background Art

[0002] Soil environment detection and analysis is the basic work for qualitatively analyzing the physical and chemical properties of soil, and can also be used for research on soil formation and development, soil resource evaluation, soil improvement, and rational fertilization. It is also an important means for environmental quality evaluation in environmental science.

[0003] Chinese Patent CN117168888B, authorized and announced on January 30, 2024, discloses a sampling device for soil environment detection. The device includes a sampling rod, a positioning component, and a driving component. Under the action of the positioning component, the sampling rod is always in a vertical state. The sampling head provided at the lower end of the sampling rod can sample the soil to ensure the accuracy of sampling. When the lower end of the sampling head touches hard soil, the resistance to the downward movement of the sampling head increases. As the driving disk is rotated, the deformation amount of the first elastic member increases, and the positive pressure provided by the first elastic member for the sampling rod downward increases. In the above application document, the sampling rod is rotated downward to cooperate with the sampling head for corresponding sampling operations. However, in some areas where the soil is relatively soft, when the sampling head is drilled downward, some soil near the top layer adheres to the surface of the sampling head, and the soil at different positions is mixed together, affecting the accuracy of the subsequent detection results of the device.

Specific implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0018] Please refer to Figures 1-5 , a soil environment detection sampling device, including a base 100, a fixed seat 200 is assembled on the top of the base 100, a servo motor 300 is assembled on the top of the fixed seat 200, the bottom of the servo motor 300 is drivingly connected with a threaded rod 400, the outside of the threaded rod 400 is threadedly connected with a sliding block 500 through setting, and a through drill barrel 600 is assembled on the sliding block 500. Start the servo motor 300 to drive the threaded rod 400 connected thereto to rotate rapidly. The sliding block 500 assembled on the threaded rod 400 is restricted by the fixed seat 200 slidably connected thereto, so as to slowly move downward, driving the drill barrel 600 assembled on the sliding block 500 to insert into the soil; Inside the drill pipe 600, a sampling assembly 800 is provided. The sampling assembly 800 includes a first hydraulic chamber 801. The first hydraulic chamber 801 is located inside the drill pipe 600 and is fixed to the drill pipe 600. A partition plate 802 is rotatably connected inside the first hydraulic chamber 801. An elastic telescopic plate 803 is fixedly connected to the side of the partition plate 802. A first force-bearing rod 804 is slidably connected to the bottom of the first hydraulic chamber 801. The bottom of the first force-bearing rod 804 is rotatably connected to an adjusting block 805. A lead screw 806 is fixedly connected to the top of the adjusting block 805. A transmission block 807 is threadedly connected to the outside of the lead screw 806. A force-bearing plate 808 is fixedly connected to the side of the transmission block 807. When the drill pipe 600 slowly moves downward, the first hydraulic chamber 801 fixedly connected to it also moves downward. When the force-bearing plate 808 moves to the base 100, the force-bearing plate 808 is squeezed by the base 100 and moves upward. The force-bearing plate 808 drives the transmission block 807 fixedly connected to it to move upward. At this time, the transmission block 807 drives the first force-bearing rod 804 to move upward through the lead screw 806. Cooperating with the first hydraulic chamber 801 in which the first force-bearing rod 804 is slidably connected, the pressure in the first hydraulic chamber 801 increases.

[0019] An arc-shaped rod 809 is slidably connected to one end of the first hydraulic chamber 801 away from the first force-bearing rod 804. A sampling head 810 is slidably connected to the other end of the first hydraulic chamber 801 away from the first force-bearing rod 804. The partition plate 802 is located inside the first hydraulic chamber 801 and on the side close to the sampling head 810. A rotating shaft 811 is rotatably connected to the inner wall of the drill pipe 600. A stop block 812 is fixedly connected to the bottom of the rotating shaft 811. When the pressure in the first hydraulic chamber 801 increases, because the partition plate 802 is rotatably connected inside the first hydraulic chamber 801 and the elastic telescopic plate 803 is connected to the side of the partition plate 802, the force in the first hydraulic chamber 801 is preferentially transmitted to the arc-shaped rod 809, causing the arc-shaped rod 809 to push the stop block 812 to rotate, so that Figure 4 viewed from the middle perspective, the stop block 812 rotates clockwise by ninety degrees to the limit position; as the force-bearing plate 808 continues to move, the liquid in the first hydraulic chamber 801 immediately squeezes the partition plate 802, causing the partition plate 802 to compress the elastic telescopic plate 803 and rotate. At this time, the force in the first hydraulic chamber 801 can be transmitted to the sampling head 810, driving the sampling head 810 to move downward, so as to extend out of the drill pipe 600 and perform corresponding fixed-point sampling operations on the soil at that place, preventing the upper-layer soil from adhering to the sampling head 810 and improving the accuracy of the subsequent detection results of the device.

[0020] When it is necessary to sample soils at different depths, insert a finger through the opening on the outside of the drill cylinder 600 and into the interior of the drill cylinder 600. Then, by rotating the adjustment block 805, the adjustment block 805 drives the screw rod 806 fixedly connected thereto to rotate. Since the transmission block 807 assembled on the screw rod 806 is restricted by the force-receiving rod 804 slidably connected thereto, the transmission block 807 moves upward, driving the force-receiving plate 808 fixedly connected thereto to move upward. In this way, the distance between the force-receiving plate 808 and the base 100 can be adjusted. Thus, the starting time for the sampling head 810 to move downward can be postponed, so as to sample deeper soils, maintaining the effect that the device can sample soils at different depths.

[0021] During use, start the servo motor 300 to drive the threaded rod 400 in transmission connection therewith to rotate rapidly. Since the sliding block 500 assembled on the threaded rod 400 is restricted by the fixed seat 200 slidably connected thereto, it slowly moves downward, driving the drill cylinder 600 assembled on the sliding block 500 to insert into the soil. As the drill cylinder 600 slowly moves downward, the hydraulic chamber 801 fixedly connected thereto also moves downward. When the force-receiving plate 808 moves to the base 100, the force-receiving plate 808 is squeezed by the base 100 and moves upward. The force-receiving plate 808 drives the transmission block 807 fixedly connected thereto to move upward. At this time, the transmission block 807 drives the force-receiving rod 804 to move upward through the screw rod 806. Cooperating with the hydraulic chamber 801 slidably connected to the force-receiving rod 804, the pressure in the hydraulic chamber 801 increases. Also, since a baffle plate 802 is rotatably connected in the hydraulic chamber 801 and an elastic telescopic plate 803 is connected to the side of the baffle plate 802, the force in the hydraulic chamber 801 is preferentially transmitted to the arc-shaped rod 809, causing the arc-shaped rod 809 to push the stopper 812 to rotate, Figure 4 viewed from the middle perspective, the stopper 812 rotates clockwise by ninety degrees to the limit position. As the force-receiving plate 808 continues to move, the liquid in the hydraulic chamber 801 immediately squeezes the baffle plate 802, causing the baffle plate 802 to compress the elastic telescopic plate 803 and rotate. At this time, the force in the hydraulic chamber 801 can be transmitted to the sampling head 810, driving the sampling head 810 to move downward, so as to extend out of the drill cylinder 600 and perform corresponding fixed-point sampling operations on the soil at that location. When it is necessary to sample soils at different depths, insert a finger through the opening on the outside of the drill cylinder 600 and into the interior of the drill cylinder 600. Then, by rotating the adjustment block 805, the adjustment block 805 drives the screw rod 806 fixedly connected thereto to rotate. Since the transmission block 807 assembled on the screw rod 806 is restricted by the force-receiving rod 804 slidably connected thereto, the transmission block 807 moves upward, driving the force-receiving plate 808 fixedly connected thereto to move upward. In this way, the distance between the force-receiving plate 808 and the base 100 can be adjusted. Thus, the starting time for the sampling head 810 to move downward can be postponed, so as to sample deeper soils. Example Two

[0022] Please refer to Figures 1-7 Based on Example One, a lockable roller 700 is assembled at the bottom of the base 100, and a stabilizing assembly 900 is provided at the bottom of the base 100. The stabilizing assembly 900 includes a second hydraulic chamber 901 and a third hydraulic chamber 902. The second hydraulic chamber 901 is arc-shaped and is assembled outside the threaded rod 400. After moving the device to a specified position through the lockable roller 700, lock the roller 700. When the device is enabled and the threaded rod 400 rotates rapidly, the second hydraulic chamber 901 assembled outside the threaded rod 400 can be driven to rotate rapidly.

[0023] An elastic telescopic rod 903 is provided on the inner wall of the second hydraulic chamber 901 to connect a slider 904, and a pressing rod 905 is slidably connected to the side of the second hydraulic chamber 901. When the second hydraulic chamber 901 rotates rapidly, the slider 904 in the second hydraulic chamber 901 is immediately under the action of centrifugal force, stretching the elastic telescopic rod 903 connected thereto, increasing the pressure in the second hydraulic chamber 901, and driving the pressing rod 905 slidably connected to the second hydraulic chamber 901 to move.

[0024] A second stress rod 906 is slidably connected to one end of the third hydraulic chamber 902. The second stress rod 906 is located on the side of the pressing rod 905 and is in contact with the pressing rod 905. A friction plate 907 is slidably connected to the other end of the third hydraulic chamber 902, and a first spring 908 is assembled on the side of the second stress rod 906. When the pressing rod 905 moves, at this time, during the rotation of the pressing rod 905, it extends synchronously, thereby pressing the second stress rod 906 and driving the second stress rod 906 to move laterally. Cooperating with the third hydraulic chamber 902 slidably connected to the second stress rod 906, the pressure in the third hydraulic chamber 902 is increased, driving the friction plate 907 slidably connected to the third hydraulic chamber 902 to move downward. The friction plate 907 then moves to the ground position and exerts a pressing force on the ground, thereby improving the overall stability of the device during use.

[0025] When the sampling head 810 starts sampling, the threaded rod 400 immediately stops rotating, and the stabilizing assembly 900 is immediately reset under the action of the first spring 908 and the elastic telescopic rod 903 for subsequent use of the device.

[0026] In use, on the basis of the first embodiment, the device is moved to a designated position through the lockable roller 700, and then the roller 700 is locked. When the device is enabled and the threaded rod 400 rotates rapidly, the hydraulic chamber two 901 assembled outside the threaded rod 400 can be driven to rotate rapidly. The slider 904 in the hydraulic chamber two 901 is then stretched under the action of centrifugal force, stretching the elastic telescopic rod 903 connected to it, increasing the pressure in the hydraulic chamber two 901, and driving the extrusion rod 905 slidably connected to the hydraulic chamber two 901 to move. At this time, during the rotation of the extrusion rod 905, it extends synchronously, thereby extruding the force-receiving rod two 906 and driving the force-receiving rod two 906 to move sideways. Cooperating with the hydraulic chamber three 902 slidably connected to the force-receiving rod two 906, the pressure in the hydraulic chamber three 902 is increased, driving the friction plate 907 slidably connected to the hydraulic chamber three 902 to move downward. The friction plate 907 then moves to the ground position and applies an extrusion force to the ground. When the sampling head 810 starts sampling, the threaded rod 400 stops rotating immediately, and the stabilizing assembly 900 is reset under the action of the first spring 908 and the elastic telescopic rod 903. Embodiment Three

[0027] Please refer to Figures 1-8 , on the basis of the first and second embodiments, a clamping assembly 1000 is provided on the outer side of the drill barrel 600. The clamping assembly 1000 includes a hydraulic chamber four 1001. One end of the hydraulic chamber four 1001 is slidably connected with an induction rod 1002. The induction rod 1002 is located on the side of the extrusion rod 905 and is in contact with the extrusion rod 905. When the extrusion rod 905 rotates and extends synchronously during the rotation process, it can extrude the induction rod 1002. Cooperating with the hydraulic chamber four 1001 slidably connected to the induction rod 1002, the pressure in the hydraulic chamber four 1001 is increased.

[0028] The other end of the hydraulic chamber four 1001 is slidably connected with a push rod 1003. A torsion spring rod 1004 is rotatably connected to the outer side of the drill barrel 600. A clamping rod 1005 is fixedly connected to the outer side of the torsion spring rod 1004. The clamping rod 1005 is fixedly connected to the push rod 1003. When the pressure in the hydraulic chamber four 1001 increases and drives the push rod 1003 slidably connected to the hydraulic chamber four 1001 to move, and since the torsion spring rod 1004 is rotatably connected to the drill barrel 600 and the torsion spring rod 1004 is fixed to the clamping rod 1005, the push rod 1003 can extrude the clamping rod 1005 and cause the clamping rod 1005 to rotate. The two clamping rods 1005 on both sides rotate synchronously to clamp the drill barrel 600 to a certain extent, further locking the drill barrel 600 on the sliding block 500 and further improving the stability of the device during use.

[0029] In use, on the basis of the first and second embodiments, when the extrusion rod 905 extends synchronously during rotation, the induction rod 1002 can be extruded, and in cooperation with the fourth hydraulic chamber 1001 slidably connected to the induction rod 1002, the pressure in the fourth hydraulic chamber 1001 is increased, driving the push rod 1003 slidably connected to the fourth hydraulic chamber 1001 to move. Also, since the torsion spring rod 1004 is rotatably connected to the drill barrel 600 and the torsion spring rod 1004 is fixed to the clamping rod 1005, the push rod 1003 squeezes the clamping rod 1005 and causes the clamping rod 1005 to rotate. The clamping rods 1005 on both sides rotate synchronously to clamp the drill barrel 600 to a certain extent.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
