Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figure 1-2 And Figure 4-5 As shown in, a sampling device for geological heritage investigation includes a bottom plate 1;

[0026] A plurality of uniformly distributed through holes 6 that penetrate up and down are provided inside the bottom plate 1. A limiting component 7 is arranged inside the through holes 6. A plurality of uniformly distributed guide tubes 2 are fixedly connected to the top of the bottom plate 1. A sampling component 3 is arranged inside the guide tubes 2. A handle rod 5 is fixedly connected to the center of the top of the bottom plate 1. During operation, the handle rod 5 facilitates the movement and handling of the device. When the device moves to a designated position for soil sampling, the bottom plate 1 is stably attached to the ground. Then, the sampling component 3 is driven to move downward for sampling. During sampling, the sampling is stably carried out through the guiding of the guide tubes 2 of the guide tubes 2. After sampling, the sampled soil is prevented from falling by the limitation of the limiting component 7. The cooperation of a plurality of sampling components 3 and a plurality of guide tubes 2 enables the device to sample different types of soil without the need to replace a new one after sampling one type of soil for another type of soil sampling. Thus, the device is convenient to use, can meet more usage requirements, and has strong practicability.

[0027] The inside of the guide tube 2 corresponds to and communicates with the inside of the through hole 6. During operation, it facilitates the movement and sampling of the sampling component 3.

[0028] A handle 4 is fixedly connected to the top end of the handle rod 5. During operation, the handle 4 facilitates the movement of the handle rod 5 and facilitates driving the device to move and handle the position.

[0029] The sampling component 3 includes limiting grooves 306 opened on the left and right sides inside the guide tube 2. Limiting blocks 305 are slidably connected inside the limiting grooves 306. A sampling cylinder 304 is fixedly connected between the two limiting blocks 305. A through threaded hole 303 is opened on the upper surface inside the sampling cylinder 304. A threaded rod 302 is threadedly connected inside the threaded hole 303. The bottom end of the threaded rod 302 is fixedly connected with a pressing plate 307, and the pressing plate 307 is movably connected with the sampling cylinder 304. During operation, by moving the threaded rod 302, the threaded rod 302 drives the sampling cylinder 304 that is threadedly connected to it to move. The sampling cylinder 304 moves downward under the limitation of the sliding connection between the limiting blocks 305 and the limiting grooves 306. Then, after the sampling cylinder 304 moves, it passes through the limiting component 7 inside the through hole 6 and is inserted into the soil, and the soil enters the sampling cylinder 304. Immediately after sampling, the threaded rod 302 is moved again to make the sampling cylinder 304 move upward and reset. The bottom of the sampling cylinder 304 is limited by the limiting component 7, and the sampled soil is prevented from falling from the through hole 6. At the same time, by rotating the threaded rod 302, the pressing plate 307 rotates and moves inside the sampling cylinder 304 to extrude the sampled soil so that it can be removed from the sampling cylinder 304 for use. Different amounts of soil can be taken by different positions of the pressing plate 307 inside the sampling cylinder 304.

[0030] The top end of the threaded rod 302 passes through the top of the sampling tube 304 and is fixedly connected with a handle plate 301 ; during operation, the handle plate 301 facilitates the rotation of the threaded rod 302 and drives the threaded rod 302 and the sampling tube 304 to move.

[0031] The limiting assembly 7 includes slots 702 provided on the front and rear surfaces of the through hole 6, and a rotating rod 703 is rotatably connected to the slot 702 through a torsion spring 704. A limiting plate 701 is fixedly connected between the two rotating rods 703 and is rotatably connected to the through hole 6. When working, the through hole 6 is blocked by the limiting plate 701, and the sampling tube 304 is supported when no sampling is performed, so that the sampling tube 304 will not fall. At the same time, the bottom of the sampling tube 304 can be blocked after the sampling is completed, and the soil after sampling is prevented from falling. The device can be easy to use. When sampling, the sampling tube 304 is pressed downward to squeeze the limit plate 701, so that the limit plate 701 rotates through the rotating rod 703, and the rotation of the rotating rod 703 drives the torsion spring 704 to be squeezed, so that the torsion spring 704 has a rebound force, so that the sampling tube 304 moves upward after the sampling is completed and the limit plate 701 is reset after being disengaged from the squeezing of the limit plate 701. The sampling tube 304 after sampling is placed on the top of the limit plate 701 without squeezing the limit plate 701 and the torsion spring 704, so that the limit plate 701 and the torsion spring 704 rotate.
