[0002] Soil sampling and testing is a crucial step in engineering testing. Sampling and testing the soil to understand its physical, chemical, and biological properties is of great significance for assessing soil quality, guiding land use, and ensuring environmental safety.

[0003] In the prior art, such as the "An Engineering Testing Sampling Device" with Chinese Patent Publication No. CN221941293U, the internal threaded tube, the fixed block, the adjusting rod and the screw cooperate with each other so that when the internal threaded tube rotates, it can drive the fixed block and the adjusting rod to move downward, thereby adjusting the height of each corner of the base plate. This allows the base plate to be adjusted to be horizontal, so that the whole device can be adapted to sampling points in different terrains, thereby improving the applicability of the whole device.

[0004] In the aforementioned prior art, although soil sampling can be completed, when the soil sample is removed from the sampling mechanism, the soil is easily stuck on the inside of the sampling drill bit because the sampling drill bit collects the soil inside. This requires the staff to constantly tap the outside of the sampling drill bit to remove the soil sample, increasing the difficulty of sample collection. Summary of the Invention

The fixed frame 18 can be moved upward by the multi-section electric telescopic rod 15, which can remove the sampling drill bit 20 from the soil. The arc-shaped plate 22 can be opened from the outside of the sampling drill bit 20 by pulling the magnetic collar 21 upward from the outside of the sampling drill bit 20, which facilitates the cleaning and discharge of the sample inside the sampling drill bit 20.

[0018] As a technical optimization of this utility model, the arc plate 22 is fixedly matched and contacted with the sampling drill bit 20 through the magnetic collar 21, and the bottom end of the arc plate 22 is rotatably installed with the sampling drill bit 20. The output end of the multi-section electric telescopic rod 15 is fixedly connected to the top of the fixed frame 18. The inner side of the mounting frame 14 is fixedly installed with a slide rail 16, and the movable plate 17 is slidably installed with the slide rail 16.

[0019] In this embodiment: by setting up the slide 16, the movable plate 17 can move vertically and stably along the slide 16 when collecting samples, so that the sampling drill bit 20 can collect soil samples.

[0020] As a technical optimization of this utility model, a mud scraper sleeve 12 is threadedly installed at the bottom of the limiting plate 10. The bottom edge of the mud scraper sleeve 12 is in contact with the sampling drill bit 20. A plurality of balls 11 are provided on the inner side of the limiting plate 10, and the balls 11 are in rolling contact with the sampling drill bit 20.

[0021] In this embodiment: by setting a limiting plate 10, the sampling drill bit 20 can roll around the ball bearing 11 inside the limiting plate 10 when rotating to collect soil samples, which facilitates the sampling operation of the sampling drill bit 20 and increases the stability of the soil collection by the sampling drill bit 20.

[0022] As a technical optimization of this utility model, two first electric telescopic rods 7 are fixedly installed on the top of the base plate 1. A support rod 8 is installed at the output end of the first electric telescopic rod 7, and a support foot 9 is fixedly installed at both ends of the support rod 8.

[0027] In this embodiment: the collection box 5 facilitates the collection of soil in batches, and the battery 4 provides power to the multi-section electric telescopic pole 15, the motor 19, and the first electric telescopic pole 7.

[0028] Working principle: In use, by pushing the fixed rod 2 and handle 3, the base plate 1 is moved to the designated position for soil sampling. Then, the first electric telescopic rod 7 drives the support rod 8 to move downward, which in turn drives the support foot 9 to apply pressure to the ground, keeping the base plate 1 stable. Then, the motor 19 drives the sampling drill bit 20 to rotate, and the multi-section electric telescopic rod 15 extends, which drives the fixed frame 18 to move downward, so that the movable plate 17 slides along the slide rail 16 to sample the soil. Finally, the multi-section electric telescopic rod 15 retracts, which drives the fixed frame 18, the movable plate 17, and the sampling drill bit 20 to reset. During the upward movement of the sampling drill bit 20, the mud scraper sleeve 12 can scrape off the mud on the outside of the sampling drill bit 20. Then, the magnetic collar 21 is pulled upward from the outside of the sampling drill bit 20, which can open the arc plate 22 from the outside of the sampling drill bit 20, making it easy to clean and discharge the sample inside the sampling drill bit 20. The sample is placed in the collection box 5 for batch collection.
