Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a soil sampling device for plateau ecological restoration. Background Technology

[0002] Ecological restoration is a comprehensive approach based on ecological principles. It is grounded in bioremediation, integrating physical, chemical, and various engineering techniques through optimized combinations to achieve the best results and lowest cost in remediating polluted environments. When soil or water is contaminated with heavy metals, plants absorb these metals to varying degrees from their rhizosphere. The amount absorbed is influenced by many factors, including the physiological characteristics of the plant roots, the composition of the rhizosphere microbial community, the pH value of the environment, the oxidation-reduction potential, the type and concentration of heavy metals, and the physicochemical properties of the soil itself.

[0003] The Inner Mongolia Plateau in my country is vast and rich in diverse ecosystems. Soil sampling is a crucial foundational step before ecological restoration work can begin, and its results play a decisive role in the formulation of subsequent restoration plans. However, most common soil sampling devices can only sample the surface layer. When sampling soil deep in the ground, it is necessary to drill a deep hole and then take soil samples at the bottom of the hole. This sampling method is cumbersome, and the drilled deep hole may collapse, making it impossible to guarantee that the soil sample taken is from deep soil. In addition, the collected soil sample is not easy to remove from the device. Therefore, this application proposes a soil sampling device for plateau ecological restoration. Utility Model Content

[0030] The beneficial effects of this utility model are:

[0031] 1. Move the device to the sampling area by pushing the handle, then control the extension of the multi-stage hydraulic cylinder. Connect the drill rod to the motor output end using the first bolt, and then install the sampling mechanism at the bottom of the drill rod. Then, run the motor to make the drill rod and the sampling mechanism at its bottom rotate clockwise. While the drill rod is rotating, control the retraction of the multi-stage hydraulic cylinder, which will move the placement plate, the rotating drill rod, and the sampling mechanism downwards. In this way, the drill bit at the bottom of the sampling mechanism can break through the soil layer and insert into the soil. The baffle and the outer protruding plate on the side wall of the sampling tube are subject to the friction of the soil and will not move into the plate groove, so the soil cannot enter the sampling tube. When the drill rod moves down to the sampling point, the sampling mechanism will be able to enter the sampling area. After determining the soil depth to be sampled, the sampling mechanism controls the motor to rotate counterclockwise. At this time, the baffle and convex plate on the side wall of the sampling tube move into the groove due to the friction of the soil, thereby opening the feed port on the side wall of the sampling tube. Through the counterclockwise rotation of the sampling tube, the deep soil can gradually enter the sampling tube. After sampling is completed, the motor is controlled to rotate clockwise again, and the multi-stage hydraulic cylinder is controlled to extend and drive the placement plate to move up, thereby removing the sampling tube from the soil. The entire soil sampling process is simple and convenient to operate, and can be completed without damaging a large area of ​​the ground. Moreover, the collected soil samples are soil from deep within the ground, which plays an important role in subsequent ecological restoration investigations.

[0032] 2. When removing the sampled soil, first unscrew the second bolt to disengage the connecting column from the connecting groove. Then, remove the top cover and sampling mechanism from the bottom of the drill rod. Next, move the limiting block in the four locking components to disengage its end from the groove on the side of the connecting plate. Then, remove the top cover from the top of the sampling tube. The collected soil sample can then be taken out from the top of the sampling tube. Removing the top cover facilitates cleaning the inside of the sampling tube for subsequent use.

[0051] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0052] Please see Figure 1 and Figure 9 This utility model provides a technical solution: a soil sampling device for plateau ecological restoration, including a carrier plate 11, which is a horizontal rectangular plate. A lower opening 12 is provided at the center of the carrier plate 11. A gate-shaped fixing frame 15 is fixedly installed on the top of the carrier plate 11. An upper opening is provided at the center of the top of the fixing frame 15, which is aligned vertically with the lower opening 12. Multi-stage hydraulic cylinders 21 are fixedly installed on the top of the carrier plate 11 and on both sides of the lower opening 12. The top ends of the two multi-stage hydraulic cylinders 21 pass through the fixing frame 15. A placement plate 22 is fixedly installed on the telescopic ends of the two multi-stage hydraulic cylinders 21. A motor 23 is fixedly installed on the top of the placement plate 22. A drill rod 25 is connected to the output end of the motor 23. The bottom end of the drill rod 25 is inserted into the upper opening at the top of the fixing frame 15. A sampling mechanism 3 is installed at the bottom end of the drill rod 25. Four sets of limiting components 6 are installed in a circular array in the upper opening.

[0053] By operating the motor 23, the drill rod 25 and the sampling mechanism 3 at its bottom are rotated clockwise. Then, by controlling the two multi-stage hydraulic cylinders 21 to move the placement plate 22 and the drill rod 25 down a certain height, the sampling mechanism 3 can be inserted into the soil. The four limiting components 6 inside the upper opening can increase the stability of the drill rod 25 during rotation.

[0054] See Figure 4 and Figure 8The sampling mechanism 3 further includes: a sampling tube 31, which is a hollow, open-top circular tube structure. An inlet 32 ​​is provided on the side wall of the sampling tube 31. A groove 33 extending into the side wall of the sampling tube 31 is provided on one side of the inlet 32. An arc-shaped baffle 34 is provided at the inlet 32, one end of which is movably inserted into the groove 33 on one side of the inlet 32. An externally protruding plate 35 is fixedly installed on the outer side of the end of the baffle 34 extending out of the groove 33. A drill bit 36 ​​is installed at the bottom of the sampling tube 31. Four connecting plates 37 are arranged in a circular array at the top of the sampling tube 31. The connecting plates 37 are arc-shaped, and a slot is provided on the inner side of each connecting plate 37. When the sampling mechanism 3 rotates clockwise in the soil, the baffle 34 and the outer protruding plate 35 at the feed inlet 32 ​​on the side wall of the sampling tube 31 are tightly closed at the feed inlet 32 ​​due to the frictional force exerted by the soil. When the sampling mechanism 3 rotates counterclockwise, the frictional force exerted by the soil on the baffle 34 and the outer protruding plate 35 will cause the baffle 34 to move into the plate groove 33, thereby opening the feed inlet 32 ​​on the outer wall of the sampling tube 31. With the continuous counterclockwise rotation of the sampling tube 31, the soil will gradually enter the sampling tube 31. Finally, the sampling mechanism 3 is rotated clockwise again, and the multi-stage hydraulic cylinder 21 is controlled to extend and push the placement plate 22 upward, so as to bring up the drill rod 25 and the sampling mechanism 3 at its bottom end.

[0055] See Figure 5 , Figure 6 and Figure 7 The top of the sampling mechanism 3 is provided with a top cover 41. Four slots 42 are evenly opened on the edge of the top cover 41. The four connecting plates 37 at the top of the sampling tube 31 are respectively inserted into the four slots 42 on the top cover 41. A connecting post 51 is fixedly installed at the center of the top of the top cover 41. The four sides of the bottom of the connecting post 51 are provided with locking components 43 between the corresponding connecting plates 37. The top of the sampling tube 31 can be closed by the top cover 41, and the connection between the two is completed by the locking components 43, so that the top cover 41 can be stably closed on the top of the sampling mechanism 3.

[0056] See Figure 4 and Figure 5 The bottom end of the drill rod 25 has a groove, and a connecting groove 52 that matches the shape of the connecting post 51 is formed at the center of the top of the groove. A threaded groove 53 that passes through the connecting groove 52 is formed on one side of the bottom end of the drill rod 25. A threaded hole is formed on the side of the connecting post 51. The connecting post 51 can be inserted into the connecting groove 52 at the bottom end of the drill rod 25. A second bolt 54 is threaded between the threaded groove 53 and the threaded hole on the connecting post 51. By inserting the connecting post 51 on the top cover 41 into the connecting groove 52 at the bottom end of the drill rod 25, and then using the second bolt 54 to fix the connecting post 51 in the connecting groove 52, the top cover 41 and the sampling mechanism 3 can be installed at the bottom end of the drill rod 25.

[0057] See Figure 5 , Figure 6 and Figure 7 The engaging assembly 43 further includes: a limiting block 431, which is L-shaped. The horizontal end of the limiting block 431 can be inserted into a slot inside the connecting plate 37. Two rod grooves 433 are provided on the side of the limiting block 431 near the connecting post 51. Two positioning rods 432 are fixedly installed on the side of the connecting post 51. The two positioning rods 432 are respectively movably inserted into the two rod grooves 433 on one side of the limiting block 431. A spring 434 is sleeved on each of the two positioning rods 432. The two ends of the spring 434 are respectively fixedly connected to the side walls of the connecting post 51 and the limiting block 431. A locking block 4 is fixedly installed at the top of the vertical part of the limiting block 431. 35. The top of the groove at the bottom of the drill rod 25 is evenly provided with four slots 436 that are adapted to the shape of the locking block 435. The locking blocks 435 in the four locking components 43 can be inserted into the corresponding slots 436 at the top of the groove. By locking the limiting block 431 into the slot on the inner side of the connecting plate 37, the top cover 41 can be fixedly installed on the top of the sampling tube 31. When the drill rod 25 is installed on the top of the top cover 41, the locking block 435 on the top of the limiting block 431 will lock into the slots 436 in the groove at the bottom of the drill rod 25, thereby fixing the position of the limiting block 431 and increasing the stability of the connection between the top cover 41 and the sampling mechanism 3.

[0058] See Figure 1 and Figure 3 A connector 24 is fixedly installed at the output end of the motor 23. A connecting groove is provided at the bottom end of the connector 24. The top end of the drill rod 25 is inserted into the connecting groove. Through holes are provided on the side of the connector 24 and the side of the top end of the drill rod 25. A first bolt 26 is inserted through the through hole on the side of the connector 24 and the through hole on the side of the top end of the drill rod 25. The top end of the drill rod 25 can be disassembled and assembled from the connector 24 by the first bolt 26. When the device is not in use, the drill rod 25 can be removed. Then, the placement plate 22 is lowered when the multi-stage hydraulic cylinder 21 is controlled to retract, thereby reducing the space occupied by the device.

[0059] See Figure 1 , Figure 2 and Figure 9 The limiting component 6 includes a fixing rod 61 and a rubber roller 62. The fixing rod 61 is C-shaped, and its two ends are fixedly connected to the bottom of the top and bottom of the fixing frame 15, respectively. The rubber roller 62 is rotatably sleeved on the middle part of the fixing rod 61, and the side wall of the rubber roller 62 is in contact with the side wall of the drill rod 25. By having four rubber rollers 62 in contact with the drill rod 25, the drill rod 25 can be prevented from shaking during rotation, thereby enabling stable deep soil sampling.

[0060] See Figure 1 and Figure 2 Rotatable rollers 13 are provided at the four corners of the bottom of the carrier plate 11. A handrail 14 is fixedly installed on the top of one end of the carrier plate 11. The handrail 14 and rollers 13 facilitate the movement of the entire device.
