Technical Field

[0001] The utility model relates to the field of soil sampling devices, in particular to an ecologically adaptable soil sampling device. Background Art

[0002] Soil sampling is an important part of environmental monitoring, scientific research, and agricultural management. Accurate soil samples can help scientists understand the quality, composition, and health of the soil, and thus formulate reasonable land management and remediation strategies. However, traditional soil sampling methods often have some limitations, such as low sampling accuracy, complex operations, and large disturbances to the soil. Especially in complex ecological environments, such as forests, wetlands, deserts and other areas with varied terrain, traditional sampling methods may not be able to meet the needs.

[0004] The above patent design is an ecological environment detection soil sampling device, which sets a pushing mechanism, inserts a pressure rod with a bolt, and drives the pressure plate to push the soil out of the sampling shovel by pressing the handle down, and then performs composition detection on the extracted soil sample to achieve the purpose of analyzing the ecological environment data. However, when the device is sampling soil, the operator needs to manually apply pressure to ensure that the sampling tube can be smoothly inserted into the ground. If multiple samplings are required, such operations may cause fatigue in the operator's hands, and when the soil inside the sampling tube needs to be taken out, it is usually necessary to use tools to open the lid of the sampling tube. This process is not only time-consuming but also not convenient. Therefore, it is necessary to design an ecologically adaptable soil sampling device that is convenient for sampling to solve the above problems. Utility Model Content

The four-way support plates of the frame are fixed with connecting plates, the connecting plates are installed with electric push rods, the telescopic rods of the electric push rods are installed with positioning cones, and the circular chassis at the bottom of the frame is provided with an opening adapted to the positioning cone.

[0010] Furthermore, it also includes a placement tube. A plurality of placement tubes are fixedly installed circumferentially on the inner wall of the circular chassis at the bottom of the frame.

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example: An ecologically adaptable soil sampling device, such as Figure 1-Figure 3 As shown, it includes a frame 1, a handle 2, a multi-stage telescopic cylinder 3, a servo motor 4, a sampling tube 5 and a central shaft 51. The frame 1 is a supporting carrier of the sampling device. The frame 1 consists of a circular chassis at the bottom and a four-way support plate at the top. A pillar is provided on the top of the frame 1. The frame 1 is equipped with a handle 2 through the top pillar. A multi-stage telescopic cylinder 3 is installed in the top pillar of the frame 1. The end of the telescopic rod of the multi-stage telescopic cylinder 3 is fixedly connected to the servo motor 4. The sampling tube 5 is installed at the bottom of the servo motor 4. The output shaft of the servo motor 4 is located in the sampling tube 5. The central shaft 51 is installed on the output shaft of the servo motor 4. The central shaft 51 extends to the lower end opening of the sampling tube 5. The lower end of the central shaft 51 is pointed. The tip facilitates the sampling tube 5 and the central shaft 51 to pierce some hard soil such as grass, woodland or sand for sampling.

[0024] like Figure 2 and Figure 3 As shown, it also includes a spiral feeding blade 6, and the spiral feeding blade 6 is provided at the lower part of the central shaft 51, and the spiral feeding blade 6 is used to evenly feed the soil into the sampling tube 5; it also includes a first spring 7 and an extrusion plate 8, and the inner wall of the sampling tube 5 is slidably mounted with an extrusion plate 8, which is located above the spiral feeding blade 6, and the central shaft 51 passes through the extrusion plate 8. A first spring 7 is provided between the extrusion plate 8 and the servo motor 4, and the first spring 7 is sleeved on the upper part of the central shaft 51.

[0025] like Figure 1 and Figure 4 As shown, it also includes a connecting plate 9, an electric push rod 10 and a positioning cone 11. The connecting plates 9 are fixed on the four-way support plates of the frame 1, and the connecting plates 9 are installed with electric push rods 10. The positioning cone 11 is installed on the telescopic rod of the electric push rod 10, and the circular chassis at the bottom of the frame 1 has an opening adapted to the positioning cone 11.

[0026] like Figure 1 、 Figure 5 and Figure 6As shown, it also includes a placement tube 12. A plurality of placement tubes 12 are fixedly installed circumferentially on the inner wall of the circular chassis at the bottom of the frame 1. The placement tube 12 is used to load containers for placing sampled soil. After sampling, the sampled soil is directly loaded onto the container on the placement tube 12, which is convenient for transfer after batch sampling; the placement tube 12 is also provided with a guide rod 13, a wedge block 14 and a second spring 15. The tube wall of the placement tube 12 is symmetrically provided with openings, and the outer side wall of the placement tube 12 is symmetrically fixed with a guide rod 13. A wedge block 14 is slidably installed on the guide rod 13, and the inclined surface of the wedge block 14 faces upward, and the wedge block 14 is used to clamp the sampling container placed in the placement tube 12. The wedge block 14 is inserted into the placement tube 12 through the opening, and a second spring 15 is sleeved on the guide rod 13 between the placement tube 12 and the wedge block 14.

[0027] When using the device to take ecological soil samples in grasslands, woodlands or sandy lands in the wild, the device is first placed on the ground for sampling. The sampling personnel can place the container for taking soil on multiple placement tubes 12 in sequence. The placement container will press the inclined surface of the wedge block 14 outward in the placement tube 12. The squeezed wedge block 14 will overcome the elastic force of the second spring 15 and open outward. When the container is completely placed in the placement tube 12, the wedge blocks 14 on both sides of the placement tube 12 will be reset under the action of the second spring 15. The container is stably clamped in the placement tube 12. When soil sampling is performed, the sampling personnel holds the handle 2 and presses the frame 1, and then activates the multi-stage telescopic cylinder 3. The telescopic rod of the multi-stage telescopic cylinder 3 will extend downward and push the servo motor 4 and the sampling tube 5 to move downward as a whole. At the same time, the servo motor 4 is activated, and the servo motor 4 drives the central shaft 51 to rotate forward through the output shaft. Before the sampling tube 5 contacts the soil surface, the bottom tip of the forward-rotating central shaft 51 will contact and pierce the soil, and the multi-stage telescopic cylinder 3 will activate the telescopic rod of the multi-stage telescopic cylinder 3. When the cylinder 3 continuously pushes the sampling tube 5 and the central shaft 51 downward to insert into the soil, the spiral feeding blade 6 on the forward rotating central shaft 51 continuously screws the soil into the sampling tube 5 until the soil continuously pushed into the sampling tube 5 contacts the squeezing plate 8. The continuously entering soil will overcome the elastic force of the first spring 7 and push the squeezing plate 8 upward. When the soil sampling is completed, the telescopic rod of the multi-stage telescopic cylinder 3 will retract upward and drive the servo motor 4 and the sampling tube 5 to move upward as a whole, so that the sampling tube 5 and the central shaft 51 are When the soil is pulled out of the soil, the servo motor 4 is controlled to reverse, and the reversed output shaft of the servo motor 4 will drive the central shaft 51 to reverse. At this time, the soil taken out will be sent out of the sampling tube 5 by the spiral feeding blade 6 in the reverse direction. Under the elastic force of the first spring 7, the squeezing plate 8 can push the soil on the upper part of the sampling tube 5 into the spiral feeding blade 6, thereby facilitating the removal of the sampled soil in the sampling tube 5. The soil taken out can be directly placed in the container on the placement cylinder 12 for temporary storage so as to be subsequently transferred and tested in batches.
