[0021] The driving assembly includes a second electric slide rail 102 and a first electric push rod 103; two front-to-back symmetrical second electric slide rails 102 are installed on the insertion rod 1; each second electric slide rail 102 is slidably connected with a slider; the slider connected to the second electric slide rail 102 is connected to two first electric push rods 103 through a U-shaped supporting plate; the output end of the first electric push rod 103 is connected to the connecting frame 105.

[0022] The support frame 2 is provided with scale lines, and the support frame 2 is provided with a photoelectric distance meter for judging the insertion depth of the support frame 2 .

[0023] The lower side of the rod 1 is in a pointed cone shape, which is convenient for manual insertion into the soil.

[0024] It also includes an inserting plate 201 ; a connecting groove 2002 is opened on one side of the supporting frame 2 close to the flap 3 ; and the inserting plate 201 is inserted into the connecting groove 2002 .

[0025] It also includes a baffle 206; the baffle 206 is arranged at the lower side of the connecting groove 2002; the baffle 206 is connected to the supporting frame 2 through a torsion spring.

[0026] It also includes an airbag 203 and a baffle 205; the airbag 203 is arranged in the plug board 201; a number of mounting holes, the same number as the connecting hole 2001, are opened on the plug board 201; a baffle 205 is clamped in each mounting hole; an air pump is arranged on the plug board 201; the air pump input end is connected to the outside; and the air pump output end is connected to the airbag 203.

[0027] The support frame 2 and the connection frame 105 are detachably connected to facilitate the disassembly and cleaning of the flap 3 .

[0028] The support frame 2 and the flap 3 are both sprayed with an anti-corrosion coating to extend the service life of the equipment.

[0029] The support frame 2 of the present invention is made of a smooth material, which reduces the friction with the soil and facilitates the insertion of the support frame 2 into the soil.

[0030] When the present invention is working, the user first carries the equipment to the sampling site, manually determines the sampling point and marks it. Next, the user fixes the insertion rod 1 around the sampling point, and then installs the support frame 2 on the mounting bracket 104 on the insertion rod 1, so that the center point of the support frame 2 is located at the exact center of the manually determined sampling point. At this time, since the flap 3 is inclined from top to bottom, a trapezoidal storage area 1001 is formed between the flap 3 and the support frame 2. When the user presses the side of the support frame 2 to insert it into the soil, the soil in the storage area 1001 is subjected to the downward pressure of the trapezoidal beveled flap 3, causing the soil on the lower side of the support frame 2 to be squeezed and become compacted, thereby making it more difficult to insert the support frame 2 into the soil. In order to solve this problem, the present invention drives the flap 3 to move upward by the second electric slide rail 102 before inserting the support frame 2 into the soil. During this process, the second electric push rod 106 rotates clockwise when viewed from the front to the back, and the second electric push rod 106 extends adaptively. When the sampler 4 is completely higher than the upper side of the support frame 2, as shown in FIG. Fig.11 After the connecting frame 105 is in the position shown, the first electric push rod 103 drives the connecting frame 105 to move rightward. Since the lower flap 3 is connected to the side wall of the supporting frame 2 through the second electric push rod 106 and both are hinged, when the connecting frame 105 moves rightward, the flap 3 rotates along the rotating shaft 109. When the upper side of the flap 3 approaches the right side wall of the supporting frame 2, the connecting frame 105 stops moving. At this time, the upper side of the flap 3 approaches the supporting frame 2, which is equivalent to reducing the distance between the right side wall of the supporting frame 2 and the flap 3, thereby facilitating the insertion of the supporting frame 2 into the soil.

[0031] The above work of the present invention solves the problems existing in the existing manual sampling of the soil surface. In the traditional method, when a sampling pit with a length, width and depth of 20m is dug manually with a shovel, 20m is the standard sampling depth, which is easy to cause the sampling pit to collapse due to stepping on the edge of the sampling pit. The soil on the side wall of the sampling pit will flow downward, causing the soil layers of different depths to mix, thereby contaminating the sample taken. The present invention effectively avoids these problems through the above design.

[0032] When the support frame 2 is inserted into the soil, the first electric push rod 103 pushes the connecting frame 105 to move leftward, and the second electric slide rail 102 drives the connecting frame 105 to move downward, so that the flap 3 is inserted into the soil. When the second electric push rod 106 connected to the flap 3 rotates to be horizontal with the ground, it is as shown in the figure. Figure 3After the state shown, the second electric slide rail 102 stops moving. Since the prior art needs to sample on the side wall of the soil pit, the second electric push rod 106 is required to push the flap 3 which is inclined from top to bottom to rotate clockwise from front to back along the rotating shaft 109. The flap 3 divides the support frame 2 into two sections, the storage area 1001 and the operation area 1002. The operation area 1002 is used for sampling by the sampler 4. However, since the storage area 1001 is a trapezoid, when the flap 3 rotates, it is difficult for the soil in the storage area 1001 to move upward, resulting in the flap 3 in contact with the storage area 1001 being subject to great resistance during rotation, hindering the movement of the flap 3. To solve this problem, when the support frame 2 is inserted into the soil, the insertion depth of the present invention is greater than 20m, so that the ground is flush with the insertion depth line 1003. Subsequently, the second electric push rod 106 pushes the flap 3 to rotate clockwise from front to back, and at the same time, the user controls the slider on the first electric slide rail 101 through the remote control to drive the support frame 2 to move upward. At this time, there is no soil in the operating area 1002 formed by the right side of the support frame 2 and the flap 3, and the soil in the trapezoidal storage area 1001 is squeezed by the flap 3, and the fallen soil will enter the operating area 1002. Since the previous insertion depth of the support frame 2 exceeds the standard depth of sampling, the operating area 1002 is not within the range of detection and sampling at this time, so the soil falling will not affect the sampling. In addition, a scale is provided on the support frame 2. When the photoelectric rangefinder detection device at the 20m scale line is flush with the ground, the information is transmitted to the remote control through the photoelectric rangefinder detection device, and an alarm is sounded through the alarm device on the remote control. At this time, the user controls the slider on the first electric slide rail 101 to stop moving, thereby further stopping the support frame 2 from moving upward. At this time, the flap 3 is vertical to the ground. During this process, part of the soil in the storage area 1001 falls into the operating area 1002 through the lower side of the flap 3, reducing the resistance of the soil in the storage area 1001 to the flap 3 during the rotation of the flap 3, making it easier for the flap 3 to rotate to open the operating area 1002. Afterwards, the third electric slide rail 107 drives the sampler 4 to move downward so that the sampler 4 is aligned with the connecting hole 2001. Then the user pulls out the plug plate 201 upward. At this time, the connecting hole 2001 is connected to the side wall of the external pit. The sampler 4 is driven by the third electric push rod 108 to pass through the connecting hole 2001 to sample the side wall of the sampling pit. When the sampler 4 is fully inserted into the side wall of the sampling pit, the user measures the insertion depth of the sampler 4 on the ground with a measuring tool and marks it. Then the user uses a shovel to move in and out at the marked position to shovel off the soil connected to the sampler 4. Then the sampler 4 is reset by the third electric push rod 108 and the third electric slide rail 107. After the sampling is completed.The second electric push rod 106 contracts to drive the flap 3 close to the right side wall of the support frame 2, and then the first electric push rod 103 drives the flap 3 to move upward. At this time, the second electric push rod 106 rotates clockwise from the front to the back and extends. In this process, the flap 3 is first moved upward to make the soil slide downward, reducing the pressure of the soil on the support frame 2, which is convenient for the user to pull out the support frame 2 later. At the same time, the flap 3 is first moved upward to expose the sampler 4 to the outside, which is convenient for the user to remove the sampler 4 first, avoiding the problem of large shaking and other problems that cause the soil sample in the sampler 4 to fall during the subsequent pulling out of the support frame 2. After that, the support frame 2 is completely pulled out of the soil, and the soil in the support frame 2 will be backfilled into the sampling pit again, reducing the user's operation process.

[0033] Furthermore, since the soil may be relatively loose, the soil sample is easy to fall off during the movement of the sampler 4 driven by the third electric slide rail 107, resulting in a deviation in the weight of the soil in the sampler 4, affecting the experimental results. Therefore, the present invention is designed with a baffle 205 and an airbag 203. After the sampler 4 takes the sample, the third electric push rod 108 drives the sampler 4 into the operating area 1002. At this time, the opening of the sampler 4 is located at the connecting hole 2001. At this time, the user inserts the plug plate 201 into the connecting hole 2001. The blocking piece 205 is located in the through groove 2002 at the connecting hole 2001, and the expansion of the airbag 203 drives the blocking piece 205 to protrude into the support frame 2. The expansion principle of the airbag 203 is as follows: an air pump is arranged on the plug plate 201, the input end of the air pump is connected with the outside, and the output end of the air pump is connected with the airbag 203; the air pump is controlled by a controller to pump gas into the airbag 203 to expand the airbag 203, and the opening of the sampler 4 is blocked by the blocking piece 205 to prevent the soil sample from falling during the movement of the sampler 4. The blocking principle of the baffle 205: the baffle 205 is clamped in the mounting hole on the plug plate 201, and the airbag 203 expands and squeezes the baffle 205, so that the baffle 205 is separated from the plug plate 201. At this time, the sampler 4 is in contact with the plug plate 201, and the baffle 205 is squeezed into the corresponding sampler 4 through the airbag 203 to seal the opening of the sampler 4. It should be noted that the baffle 205 is a disposable product and can be replaced with a new one. It should be noted that when the sampler 4 takes samples through the connecting hole 2001, since an insertable plug-in plate 201 is provided inside the support frame 2, the connecting groove 2002 on the support frame 2 is connected to the connecting hole 2001, resulting in part of the soil entering the connecting groove 2002 and accumulating inside the support frame 2 during sampling. Therefore, after the support frame 2 is completely pulled out of the soil manually, the plug-in plate 201 is pressed downward manually, and the baffle 206 on the lower side of the support frame 2 is squeezed by the plug-in plate 201 to open the baffle 206 and discharge the soil accumulated inside the connecting groove 2002.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
