Description

Technical Field

[0001] This invention relates to the field of soil sampling technology, and more specifically, to a soil sampling device for mine ecological restoration. Background Technology

[0002] Mine ecological restoration is a complex and systematic undertaking, involving the restoration and reconstruction of the ecological environment damaged by mineral resource development. Soil reconstruction is a crucial component of mine ecological restoration, primarily involving the reconstruction of a suitable soil profile through engineering and biological measures to restore soil productivity. Soil sampling is necessary before soil reconstruction can begin, and the accuracy of soil sampling directly impacts the reliability of subsequent analytical results.

[0003] Current sampling devices require waiting for the sample to be poured out and the sampling tube to be cleaned after each sampling before they can continue to the next depth of sampling, which reduces sampling efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a soil sampling device for mine ecological restoration, which has two sets of sampling components that can be used alternately. The device can switch the position of the sampling components after each sampling is completed, so that the other set of sampling components can be cleaned while one set of sampling components is sampling, thereby improving sampling efficiency.

[0005] This invention is achieved through the following technical solution: a soil sampling device for mine ecological restoration, comprising:

[0006] The base, with casters at each of its four corners;

[0007] A vertical seat is vertically disposed on a base. The vertical seat is provided with a lifting seat and a lifting component for driving the lifting seat to move along the height direction of the vertical seat. The lifting seat is provided with a drive assembly.

[0008] A sampling mechanism includes a mounting base and two sets of sampling components. The mounting base includes a fixed part and a flipping part hinged to both sides of the fixed part. The fixed part is rotatably mounted on a base. A rotating component for driving the fixed part to rotate is provided on one side of the base. The two sets of sampling components are respectively mounted on the flipping parts on both sides and can move towards the vertical base to directly below the driving component. Each sampling component includes a sampling rod and a sampling cylinder. The sampling rod slides through the flipping part, and the sampling cylinder is located at the bottom end of the sampling rod and below the flipping part.

[0009] A receiving mechanism is provided on the outer side of the base and is positioned directly opposite the sampling component located away from the vertical seat.

[0010] The rotating part and the fixed part are provided with an elastic rotating member for keeping the rotating part in an inclined state. The vertical seat is provided with a pressing member for pressing the rotating part to a horizontal state. The bottom of the driving assembly is provided with a first connecting member. Both sets of sampling assemblies are provided with a second connecting member. When the rotating assembly drives the fixed part to rotate and moves one of the rotating parts toward the direction of the vertical seat, the pressing member presses the rotating part to a horizontal state and the second connecting member can be connected to the first connecting member.

[0011] Furthermore, the pressing member includes a horizontal plate and arc-shaped plates symmetrically arranged on both sides of the horizontal plate. The end of the arc-shaped plate away from the horizontal plate is higher than the end of the arc-shaped plate close to the horizontal plate. Arc-shaped abutment surfaces are provided on both sides of the flipping part away from the fixing part.

[0012] Furthermore, the drive assembly includes a drive motor, which is fixedly mounted on the lifting seat. A drive shaft is connected to the output shaft of the drive motor. The first connecting member is a connecting block, which is coaxially mounted at the bottom end of the drive shaft and located below the lifting seat. Connecting slots are provided on both sides of the connecting block. When the second connecting member is inserted into the connecting slot, the sampling assembly and the drive shaft are in a coaxial state.

[0013] Furthermore, the second connector includes a first horizontal segment, a second horizontal segment, and a connecting segment. The first horizontal segment is fixedly mounted on the sampling rod. The second horizontal segment is parallel to the first horizontal segment and located above the first horizontal segment. The connecting segment connects the second horizontal segment and the first horizontal segment.

[0014] Furthermore, the connecting groove includes a lower groove and an upper groove that are interconnected. The width of the upper groove is the same as the width of the second horizontal segment, and the width of the lower groove is greater than the width of the upper groove, with inclined surfaces provided on both sides of the lower groove.

[0015] Furthermore, the receiving mechanism includes a receiving plate, a placement hole is provided in the middle of the receiving plate, a receiving cylinder is placed in the placement hole, an annular liner is provided on the top of the receiving cylinder that can fit against the receiving plate, and a telescopic folding section is provided in the middle of the receiving cylinder.

[0016] Furthermore, the base is provided with a transverse moving assembly for driving the receiving plate to move along the width direction of the base. The transverse moving assembly includes a transverse moving motor, a drive screw, a guide rod, and a transverse moving block. The base is provided with two support seats. The drive screw is rotatably disposed between the two support seats. The guide rod is fixedly disposed between the two support seats. The transverse moving motor is fixedly disposed on one of the support seats, and the output shaft of the transverse moving motor is fixedly connected to the drive screw. The transverse moving block has a threaded hole that mates with the drive screw and a through hole that mates with the guide rod. The receiving plate is fixedly connected to the transverse moving block.

[0017] Furthermore, the transverse component is also provided with a cleaning mechanism. The transverse component includes two transverse blocks, the receiving mechanism is disposed on one of the transverse blocks, and the cleaning mechanism is disposed on the other transverse block. The cleaning mechanism includes a support plate, a rotating disk, and a cleaning rod. The rotating disk is rotatably connected to the support plate, and a rotating handle is disposed at an eccentric position at the bottom of the rotating disk. The cleaning rod is slidably disposed on the rotating disk.

[0018] Furthermore, the cleaning rod includes a side rod for cleaning the side wall of the sampling cylinder and a top rod for cleaning the top wall of the sampling cylinder. The side rod is slidably connected inside the rotating disk, the top rod is fixedly installed at the top of the side rod, and a positioning block is provided at the bottom of the side rod. The rotating disk has a positioning groove for the positioning block to be inserted, and the support plate has a through groove for the positioning block to pass through.

[0019] Furthermore, the rotating assembly includes a rotating motor, a worm gear, and a worm. The bottom end of the fixed part is rotatably connected to the base via a rotating shaft. The worm gear is coaxially connected to the rotating shaft. Two mounting blocks are provided on the base. The worm is rotatably disposed between the two mounting blocks and meshes with the worm gear. The rotating motor is disposed on one of the mounting blocks and can drive the worm to rotate.

[0020] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0021] 1. This invention provides a set of sampling components at each end of the mounting base. By rotating the mounting base through the rotating component, the positions of the two sets of sampling components can be switched to achieve alternating use. This allows the other set of sampling components to be cleaned while one set is sampling, thereby improving sampling efficiency. Furthermore, by providing a first connector on the drive component and a second connector on both sets of sampling components, the connection process between the drive component and the sampling components is facilitated, eliminating the need for a cumbersome connection process and further improving work efficiency.

[0022] 2. The present invention provides a flipping part hinged at both ends of the mounting base, which is driven to flip upward by an elastic flipping member. A pressing member is provided on the vertical base to rotate the flipping member to a horizontal state. This makes the sampling component that has not been sampled in an inclined state to facilitate the discharge and cleaning of the sample, and makes the sampling component that is about to be sampled in a vertical state to facilitate the connection with the driving component.

[0023] 3. The present invention sets a transverse component on the base and arranges two transverse blocks on the transverse component to drive the receiving mechanism and the cleaning mechanism to move synchronously. The receiving mechanism is moved to the sampling component facing away from the vertical seat so as to receive the sample. Then, the transverse component drives the receiving mechanism away from the sampling component, while the cleaning mechanism approaches the sampling component and can clean the sampling cylinder.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] Example

[0035] The following is for reference Figures 1-7 As shown in the illustration, and further illustrated with specific embodiments, this embodiment provides a soil sampling device for mine ecological restoration. (Refer to...) Figure 1As shown, the structure includes a base 1, a vertical seat 2, a sampling mechanism 3, and a receiving mechanism 4. Rollers 11 are provided at each of the four corners of the base 1 to facilitate pushing the entire structure to a designated position for use. The vertical seat 2 is vertically welded to the base 1. A lifting seat 21 and a lifting component 22 for driving the lifting seat 21 to move along the height direction of the vertical seat 2 are provided on the vertical seat 2. A drive assembly 23 is provided on the lifting seat 21. The sampling mechanism 3 includes a mounting base 31 and two sets of sampling components 32. The mounting base 31 is rotatably mounted on the base 1, and the two sets of sampling components 32 are respectively located at both ends of the mounting base 31. The receiving mechanism 4 is located on the outer side of the base 1 and can directly face the sampling components 32 on the side away from the vertical seat 2. Push the base 1 to the designated sampling position, rotate the mounting base 31 to connect one set of sampling components 32 to the drive component 23. When the drive component 23 drives the sampling components 32 to rotate, the lifting component 22 drives the drive component 23 to descend as a whole, thus inserting the sampling components 32 into the ground for soil sampling. After sampling, remove the sampling components 32 from the ground and rotate the mounting base 31 180°. The sampling components 32 containing soil are rotated to face the feeding mechanism 4 to facilitate the discharge of the collected soil. After the soil is discharged, the sampling components 32 are cleaned. At the same time, another set of sampling components 32 is rotated to be directly below the drive component 23. Connecting this set of sampling components 32 to the drive component 23 enables the next sampling. In this embodiment, the lifting component 22 is a motor screw assembly. In other embodiments, a cylinder or hydraulic cylinder can also be used as the lifting component 22.

[0036] Reference Figure 2 , Figure 3 As shown, the mounting base 31 includes a fixed part 311 and a flipping part 312 hinged to both sides of the fixed part 311. An elastic flipping member 313 is provided between the flipping part 312 and the fixed part 311 to keep the flipping part 312 in an inclined state. The bottom end of the fixed part 311 is provided with a rotating shaft 3111 and is rotatably mounted on the base 1. A rotating assembly 33 is provided on one side of the base 1 to drive the rotating shaft 3111 to rotate. Two sets of sampling assemblies 32 are respectively provided on the flipping parts 312 on both sides and can move towards the vertical base 2 to directly below the driving assembly 23. The sampling assembly 32 includes a sampling rod 321 and a sampling cylinder 322. The sampling rod 321 slides through the flipping part 312, and the sampling cylinder 322 is provided at the bottom end of the sampling rod 321 and located below the flipping part 312. The bottom surface of the flipping part 312 is provided with a magnetic sheet 314. When the sampling cylinder 322 moves upward to abut against the flipping part 312, the top of the sampling cylinder 322 can be attracted to the magnetic sheet 314, thereby fixing the position of the sampling rod 321 and the sampling cylinder 322 on the flipping part 312.

[0037] During sampling, the mounting base 31 is rotated by the rotating component 33 to move one set of sampling components 32 to below the driving component 23. Then, the flipping part 312 corresponding to this set of sampling components 32 is flipped to a horizontal state, so that the sampling rod 321 is in a vertical state, which facilitates the connection between the sampling rod 321 and the driving component 23. The flipping part 312 at the other end is flipped upward under the action of the elastic flipping member 313, and the corresponding sampling cylinder 322 is tilted to facilitate the discharge of soil and the cleaning of the sampling cylinder 322. In this embodiment, the elastic flipping member 313 is a spring sheet. In other embodiments, a spring or torsion spring can also be used as the elastic flipping member 313.

[0038] Reference Figure 2 As shown, the drive assembly 23 includes a drive motor 231, which is fixedly mounted on the lifting base 21. A drive shaft 232 is connected to the output shaft of the drive motor 231. A first connecting member 25 is provided at the bottom end of the drive shaft 232. The first connecting member 25 is a cylindrical connecting block coaxially connected to the bottom end of the drive shaft 232. Connecting slots 251 are symmetrically provided on both sides of the connecting block. A second connecting member 323 is provided on the sampling rod 321 of both sets of sampling assemblies 32. When the second connecting member 323 is inserted into the connecting slot 251, the sampling assembly 32 and the drive shaft 232 are coaxial. In this state, when the drive motor 231 drives the drive shaft 232 to rotate, it can drive the sampling assembly 32 to rotate synchronously to facilitate penetration into the soil.

[0039] Reference Figure 1 , Figure 2 As shown, the vertical base 2 is provided with a pressing member 24 for pressing the flipping part 312 to a horizontal state. The pressing member 24 includes a horizontal plate 241 and arc-shaped plates 242 symmetrically arranged on both sides of the horizontal plate 241. The end of the arc-shaped plate 242 away from the horizontal plate 241 is higher than the end of the arc-shaped plate 242 close to the horizontal plate 241. Arc-shaped abutment surfaces 3121 are provided on both sides of the end of the flipping part 312 away from the fixed part 311. When the rotating assembly 33 drives the fixed part 311 to rotate and moves one of the flipping parts 312 towards the vertical base 2, the pressing member 24 presses the flipping part 312 to a horizontal state, so as to facilitate the connection between the driving assembly 23 and the corresponding sampling assembly 32 through the first connecting member 25 and the second connecting member 323.

[0040] Reference Figure 3As shown, the rotating assembly 33 includes a rotating motor 331, a worm gear 332, and a worm 333. The worm gear 332 is coaxially connected to the rotating shaft 3111 at the bottom of the fixed part 311. Two mounting blocks 334 are provided on the base 1. The worm 333 is rotatably disposed between the two mounting blocks 334 and meshes with the worm gear 332. The rotating motor 331 is disposed on one of the mounting blocks 334 and can drive the worm 333 to rotate. When the rotating motor 331 drives the worm 333 to rotate, the worm gear 332 rotates under the meshing action of the worm 333 and drives the mounting base 31 to rotate through the rotating shaft 3111. This causes one set of sampling components 32 to move towards the driving assembly 23. When it moves to the designated position, the corresponding second connecting member 323 connects to the connecting groove 251 of the first connecting member 25. At the same time, the other set of sampling components 32 moves away from the driving assembly 23. When it is necessary to switch the positions of the two sets of sampling components 32, the rotation motor 331 is started and the output shaft of the rotation motor 331 is rotated in the opposite direction to change the positions of the two sets of sampling components 32. During this process, the positions of the two sets of second connectors 323 also change accordingly. The second connectors 323 that were originally connected to the first connector 25 are moved out, and the second connectors 323 that were originally far away from the first connector 25 are connected to the first connector 25.

[0041] Reference Figure 2 , Figure 4As shown, the second connector 323 includes an integrally formed first horizontal segment 3231, a second horizontal segment 3232, and a connecting segment 3233. The first horizontal segment 3231 is welded to the sampling rod 321. The second horizontal segment 3232 is parallel to the first horizontal segment 3231 and located above the first horizontal segment 3231. The connecting segment 3233 connects the second horizontal segment 3232 and the first horizontal segment 3231. The connecting groove 251 includes a lower groove 2511 and an upper groove 2512 that are interconnected. The width of the upper groove 2512 is the same as the width of the second horizontal segment 3232. The width of the lower groove 2511 is greater than the width of the upper groove 2512, and inclined surfaces 2513 are provided on both sides of the lower groove 2511. When the rotating component 33 drives the mounting base 31 to rotate, the movement trajectory of the second connecting member 323 is a curve rather than a simple translational movement. Therefore, by setting inclined surfaces 2513 on both sides of the lower groove 2511 to make the opening of the lower groove 2511 flared out, it is easier for the second horizontal segment 3232 to enter. After the second horizontal segment 3232 enters the lower groove 2511, when the driving component 23 moves downward, it can allow the second horizontal segment 3232 to enter the upper groove 2512, so as to further limit the position of the second horizontal segment 3232, thereby ensuring the synchronicity of the movement of the sampling component 32 and the driving shaft 232 and preventing the connection from becoming loose. During the process of moving the sampling rod 321 and the sampling cylinder 322 upward after sampling, the driving shaft 232 does not need to rotate. Therefore, even after the second horizontal segment 3232 moves into the lower groove 2511, it is not easy for it to become loose.

[0042] Reference Figure 1 , Figure 5 As shown, a transverse moving assembly 5 is provided on the base 1, and a receiving mechanism 4 is slidably mounted on the transverse moving assembly 5. The transverse moving assembly 5 includes a transverse moving motor 51, a drive screw 52, ​​a guide rod 53, and two transverse moving blocks 54. Two support seats 55 are welded to the base 1. The drive screw 52 is rotatably mounted between the two support seats 55, and the guide rod 53 is welded between the two support seats 55. The transverse moving motor 51 is fixed on one of the support seats 55, and the output shaft of the transverse moving motor 51 is fixedly connected to the drive screw 52. The transverse moving block 54 has a threaded hole that mates with the drive screw 52 and a through hole that mates with the guide rod 53. The receiving mechanism 4 is fixedly connected to one of the transverse moving blocks 54, and a cleaning mechanism 6 is mounted on the other transverse moving block 54. When the transverse moving motor 51 is started, it drives the drive screw 52 to rotate, which in turn drives the two transverse moving blocks 54 to move synchronously, thereby driving the receiving mechanism 4 and the cleaning mechanism 6 to move synchronously. After sampling is completed, the receiving mechanism 4 is moved to the sampling component 32 facing away from the vertical seat 2 to facilitate the receipt of the sample; then the transverse component 5 drives the receiving mechanism 4 away from the sampling component 32, while the cleaning mechanism 6 approaches the sampling component 32 and can clean the sampling cylinder 322.

[0043] Reference Figure 5 As shown, the receiving mechanism 4 includes a receiving plate 41, which is fixed on one of the transverse blocks 54. The receiving plate 41 has a placement hole in the middle, and a receiving cylinder 42 is placed in the placement hole. The top of the receiving cylinder 42 is provided with an annular liner 421 that can fit with the receiving plate 41. The middle of the receiving cylinder 42 is provided with a telescopic folding section 422 so that the height of the receiving cylinder 42 can be changed as needed, thereby changing the volume when holding soil.

[0044] Reference Figure 5 , Figure 6 As shown, the cleaning mechanism 6 includes a support plate 61, a rotating disk 62, and a cleaning rod 63. The support plate 61 is fixed to another transverse block 54, and the rotating disk 62 is rotatably connected to the support plate 61. A rotating handle 621 is provided at an eccentric position at the bottom of the rotating disk 62, and the cleaning rod 63 is slidably disposed on the rotating disk 62. When the transverse component 5 drives the cleaning mechanism 6 to move as a whole, the cleaning rod 63 is moved downward to reach the bottom of the sampling cylinder 322; after moving to the designated position, the cleaning rod 63 is moved upward, and the operator holds the rotating handle 621 to drive the rotating disk 62 to rotate, thereby enabling the cleaning rod 63 to clean the inner wall of the sampling cylinder 322.

[0045] Reference Figure 6 , Figure 7 As shown, the cleaning rod 63 includes a side rod 631 for cleaning the side wall of the sampling cylinder 322 and a top rod 632 for cleaning the top wall of the sampling cylinder 322. The side rod 631 is slidably connected inside the rotating disk 62, and the top rod 632 is welded to the top of the side rod 631. A positioning block 633 is provided at the bottom end of the side rod 631. The rotating disk 62 has a positioning groove 622 for the positioning block 633 to be inserted, and the support plate 61 has a through groove 611 for the positioning block 633 to pass through. By passing the positioning block 633 through the through groove 611 and pressing it into the positioning groove 622, the relative position of the positioning block 633 and the rotating disk 62 can be fixed, allowing the rotating disk 62 to smoothly drive the cleaning rod 63 to rotate. To improve the stability of the positioning block 633 in the positioning groove 622, the positioning block 633 is made of magnetic material, or rubber pads are provided around the edge of the positioning block 633 to improve its stability in the positioning groove 622.
