Description

Technical Field

[0001] This utility model relates to the field of soil and rock sampling technology, specifically a soil and rock sampling device for soil monitoring, which is suitable for application in fields such as geological exploration, civil engineering and geotechnical engineering. Background Technology

[0002] Currently, there are many types of existing soil and rock sampling devices. For example, the relatively advanced CN202320492426.8 discloses "a soil and rock sampling device," which includes a base plate with support columns at each of the four corners of the bottom. A first motor is located on one side of the base plate, and a groove is provided on the base plate. A screw driven by the first motor is located in the groove, and a moving block is provided on the screw. A guide structure is provided at the bottom end of the moving block, and a connecting rod is hinged to the top of the moving block. A sampling box is hinged to one side of the top of the base plate, and the top of the connecting rod is hinged to one side of the sampling box. An electric telescopic rod is located at the top of the sampling box, and the telescopic rod extends... The device is equipped with a movable plate at one end, and a second motor at the bottom of the movable plate. The output end of the second motor is equipped with a drill rod. This device can be easily folded and stored, making it convenient for movement and transportation and greatly improving safety performance. It can also remain stable during sampling and has high stability. However, like most current sampling devices, this device uses a motor to drive a rotating rod to rotate, causing the drill bit to drill into the ground and using the conveying teeth to carry out the rock and soil. This method generally suffers from the disadvantage of encountering shaking during the journey after sampling, which can easily cause the rock and soil to fall out from the inside of the conveying teeth, thereby reducing work efficiency and monitoring accuracy.

[0003] Therefore, it is of practical significance to develop a soil sampling device for soil monitoring that is both efficient and accurate. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing methods and provide a soil sampling device for soil monitoring that can not only sample efficiently and stably, but also prevent material from falling due to shaking and improve monitoring accuracy.

[0005] To accomplish the above tasks, this utility model adopts the following technical solution:

[0006] Soil sampling devices for soil monitoring address the problems of soil samples easily falling off when shaken, resulting in low work efficiency and low monitoring accuracy. The device includes a main body, a sampler with a built-in hydraulic lifting device and sampling mechanism, a stabilizing mechanism on both sides of the main body, a loading plate with pulleys at the bottom and holes adapted to the sampler diameter, and a front control panel. This design enables efficient and stable sampling, prevents material loss due to shaking, and improves monitoring accuracy.

[0007] Compared with the prior art, this utility model has the following advantages or effects:

[0008] Because of the sampling mechanism, when the sampler reaches the designated position, the circuit board drives the electrically controlled telescopic rods at both ends to move. The telescopic rods then push the movable plate and the sampling head on the plate outward. At the same time, the limiting block and the guide plate are linked, providing limiting and guiding functions for the movement, thus effectively avoiding movement deviation and ensuring stable sampling. At the same time, when the sampling head contacts the sealing component, the sealing block and the return spring inside will open and close due to pressure. After opening and closing to the appropriate size, the sampling head can extend and perform sampling. After sampling, the sampling head will move back to the inner wall of the sampling chamber. At the same time, the sealing component will lose its linkage with the sampling head and close, thus effectively preserving the collected sample. In addition, because the device is equipped with pulleys at the bottom, it is convenient to move to different locations and is highly practical. Attached Figure Description

The movable plate 504 is provided with two guide plates 508 connected to the limiting blocks 507 to form the electrically controlled telescopic rods 503, which can push the movable plate 504 and the sampling head 505 on the plate outward. At the same time as pushing, the limiting blocks 50 and the guide plates 508 are linked to provide limiting and guiding functions for moving sampling.

[0020] The stabilizing mechanism 6 consists of a servo motor 602 and a bearing 603 housed within an equipment housing 601. A threaded rod 604, connected to the servo motor 602, is fixedly connected to the inner wall of the bearing 603. An internally threaded block 605, extending to the outside of the equipment housing 601, is threaded onto the threaded rod 604. A sliding groove, adapted to the internally threaded block 605, is provided on the equipment housing 601, with its inner wall slidably connected to the threaded block 605. One end of the internally threaded block 605 extending to the outside of the equipment housing 601 is fixedly connected to an extension plate 606 and a second servo motor 607. The plate 606 contains a digging rod 608 connected to the shaft of the second servo motor 607. When fixed, the extension plate 606 is raised and lowered by the linkage of the first servo motor 602, bearing 603, threaded rod 604, and internal threaded block 605. The extension plate 606 moves towards the ground. Through the cooperation between the output end of the second servo motor 607 and the internal shaft, the digging rod 608 rotates stably. The digging rod 608 moves slowly into the ground through the movement of the internal threaded block 605. The two digging rods 608 have strong stability when entering the ground.

[0021] The inner wall of the limiting block 507 of the sampling mechanism 5 is slidably connected to the outer wall of the guide plate 508.

[0022] Each of the sampling mechanism 5 enclosure components 509 includes two return springs 5091. The through hole 506 is provided with two enclosure blocks 5092. The two enclosure blocks 5092 with sliders 5063 are in contact with each other and the upper part of the two blocks 5092 is provided with return springs 5091. The sliders 5093 and the sampler 4 are slidably connected.

[0023] The main body 1 of the device is provided with stabilizing mechanisms 6 on the left and right sides.

[0025] The inner wall of the extension plate 606 of the stabilizing mechanism 6 is fixedly connected to the excavator rod 608 via a built-in rotating shaft.

[0026] During operation, when the sampler 4 reaches the designated position, the circuit board 502 will drive the electrically controlled telescopic rods 503 at both ends to move. Then, the electrically controlled telescopic rods 503 will push the movable plate 504 and the sampling head 505 on the plate outward. At the same time, the limiting block 507 and the guide plate 508 can be linked together to provide limiting and guiding functions for the movement and avoid movement deviation.

Finally, after the sampling is completed, the sampling head 505 will move back into the sampling cavity 501. At the same time, the sealing component 509 will lose the linkage with the sampling head 505 and close, thereby effectively preserving the collected sample.
