[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0025] Embodiment 1:

[0026] Referring to Figures 1-5 , a portable soil detection device includes a box body 1, and further includes: a detector 5 is fixedly connected inside the box body 1, a connecting wire 51 is connected to the detector 5, and the other end of the connecting wire 51 is connected to a sampler 52; the box body 1 is threadedly connected with a threaded rocker 2, and the threaded rocker 2 is detachable; a sampling cylinder 4 is threadedly connected below the threaded rocker 2, the bottom of the sampling cylinder 4 is provided with an external thread, and multiple sampling cylinders 4 can be connected in series by threads; a plurality of groups of detection holes 41 are equally spaced on the side wall of the sampling cylinder 4;

[0027] In the present utility model, the threaded rocker 2 is installed on the box body 1 through threaded connection. By rotating the threaded rocker 2, up-and-down movement can be achieved. The upper part of the sampling cylinder 4 has internal threads so that it can be threadedly connected to the threaded rocker 2. At the same time, the external threads provided at the lower part of the sampling cylinder 4 can be connected to the internal threads of the sampling cylinder 4, so that the length adjustment of the sampling cylinder 4 can be realized by connecting the sampling cylinders 4 in series. Furthermore, the soil at different depths can be detected by adjusting the length. The threaded part of the threaded rocker 2 is slightly longer than the length of the sampling cylinder 4. Thus, when the user sets up and fixes the box body 1, the sampling cylinder 4 can be driven to rotate and move downward by rotating the threaded rocker 2, and then the sampling cylinder 4 can be driven into the deep soil. After each sampling cylinder 4 is driven in, the connection between the sampling cylinder 4 and the threaded rocker 2 can be released by rotating the threaded rocker 2 in the reverse direction, and the threaded rocker 2 can be moved upward. At this time, if the sampling cylinder 4 has not reached the detection depth, a connected sampling cylinder 4 can be added to the sampling cylinder 4, and the connection with the newly connected sampling cylinder 4 can be completed by rotating the threaded rocker 2 in the forward direction, and the sampling cylinder 4 can continue to be driven into the soil. When the sampling cylinder 4 reaches the preset detection depth, the sampling cylinder 4 together with the soil can be pulled out, and the detection needle on the sampler 52 can be inserted into the detection hole 41 to detect the soil at different depths. At the same time, since the detection holes 41 are arranged in multiple groups at equal intervals, the user can detect the soil data at multiple depths at one time, and the soil brought out can also be taken back to the laboratory for further detection.

[0028] Embodiment 2:

[0029] Refer to Figures 1-5 , which is basically the same as Embodiment 1. Further: The sampler 52 is provided with internal threads, the sampler 52 can be threadedly connected to the sampling cylinder 4, the box body 1 is threadedly connected with a three-legged bracket 3, the lower part of the three-legged bracket 3 is connected with a fixed leg 31 through a rotating shaft, a telescopic leg 32 is slidably connected inside the fixed leg 31, the lower end of the telescopic leg 32 is fixedly connected with a connecting leg 33, the connecting leg 33 is connected with a pressing rod 34 through a rotating shaft, a wireless receiver 53 is inserted and connected to the side wall of the detector 5, a hinge 13 is fixedly connected to the side wall of the box body 1, the hinge 13 is fixedly connected with a box cover 12, and a storage drawer 14 is arranged inside the box body 1;

[0030] In the present utility model, the sampler 52 can be connected to the bottom of the sampling cylinder 4 through internal threads. While the connection line 51 transmits data in the air duct, it can also charge the power supply built in the sampler 52. The connection line 51 can be separated from the sampler 52. When the sampler 52 is disconnected from the connection line 51, it will automatically connect to the wireless receiver 53. The user can drive the sampler 52 into the drilled hole through the sampling cylinder 4 and detect the soil at the bottom of the hole. The detection data is wirelessly sent to the wireless receiver 53, so that the soil data at the bottom of the hole can be obtained;

[0031] The fixed leg 31 has a maximum opening angle. When the fixed leg 31 is opened to the maximum angle, the bottom end of the connecting leg 33 is exactly flush with the ground, so that the tripod 3 can stably support the box body 1. The pressure bar 34 can be rotated through the rotating shaft to be closed and opened. After the pressure bar 34 is opened, the user can step on the pressure bars 34 at both ends to stabilize the tripod 3 by his own weight, so that it is not necessary for the user to fix the box body 1 and the tripod 3 during drilling and sampling. When the user needs to collect the tripod 3, the pressure bar 34 can be folded up first and slid into the fixed leg 31 together with the telescopic leg 32 to complete the storage;

[0032] A sliding hole is provided on the box cover 12, so that when the box cover 12 is closed, it will not affect the connection and rotation of the threaded rocker 2;

[0033] The storage drawer 14 can be used to store the disassembled threaded rocker 2, the tripod 3, the sampling tube 4 and personal items;

[0034] When in use, the user can first connect the tripod 3 to the box body 1, then install the threaded rocker 2 on the box body 1, and then connect the sampling tube 4 to the threaded rocker 2, and then rotate the threaded rocker 2 to move the sampling tube 4 downward for sampling. During the sampling process, both feet need to step on the pressure bar 34 to keep the box body 1 stable. If one section of the sampling tube 4 cannot reach the detection depth, the threaded rocker 2 can be rotated in the reverse direction to disconnect the threaded rocker 2 from the sampling tube 4 and install a section of the sampling tube 4 between them and then continue sampling. Repeat this process until the sampling depth is reached. After sampling, the detection needle on the sampler 52 can be inserted into the detection hole 41 to detect the soil at different depths, or the dynamic sampler 52 can be installed at the bottom of the sampling tube 4 and inserted into the soil at the bottom of the drilled hole for detection.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
