The second driving member 5-8 is installed on the front surface of the side frame 1-2, and the output end of the second driving member 5-8 is connected with the moving seat 5-3. A first driving member 5-2 is installed on the moving seat 5-3. The output end of the first driving member 5-2 is connected with a bottom plate 5-4. The top surface of the bottom plate 5-4 is installed with a support plate 5-5. A slide rail 5-6 is installed at the rear side of the support plate 5-5. A slide block 5-7 matching the slide rail 5-6 is installed on the moving seat 5-3. The sampling mechanism 6 is installed on the bottom surface of the bottom plate 5-4. The cooperation of the slide rail 5-6 and the slide block 5-7 improves the stability of the lifting process of the bottom plate 5-4.

[0043] During use, the first driving member 5-2 drives the bottom plate 5-4 to descend, thereby driving the sampling mechanism 6 to descend for sampling. After sampling, the first driving member 5-2 drives the bottom plate 5-4 to rise, thereby driving the sampling mechanism 6 to rise. The second driving member 5-8 drives the moving seat 5-3 to move backward, so that the sampling mechanism 6 moves above the sample storage cylinder 4-4. The first driving member 5-2 drives the bottom plate 5-4 to descend, thereby driving the sampling mechanism 6 to descend and putting the sample into the sample storage cylinder 4-4. During the process of placing the sample, the height of the sample bracket 3 can also be adjusted by the lifting mechanism 2 to facilitate the sampling mechanism 6 to place the sample.

[0044] As Figures 7-9As shown, the sampling mechanism 6 includes a connecting frame 6-1. The top of the connecting frame 6-1 is connected to the bottom plate 5-4. A fixed cylinder 6-2 is connected to the bottom of the connecting frame 6-1. A rotating cylinder 6-3 is rotatably installed below the fixed cylinder 6-2 through a bearing. A driving component for driving the rotation of the rotating cylinder 6-3 is installed on the outer side of the rotating cylinder 6-3. A spiral blade 6-3-1 is connected to the outer wall of the rotating cylinder 6-3. A pointed tooth 6-3-2 is connected to the bottom of the rotating cylinder 6-3. A push plate 6-8 is arranged inside the fixed cylinder 6-2. A third driving member 6-7 for driving the push plate 6-8 is arranged above the push plate 6-8; The driving component includes a worm gear 6-4. The worm gear 6-4 is installed on the outer wall of the rotating cylinder 6-3. A worm 6-5 is meshed and connected to one side of the worm gear 6-4. A sampling motor 6-6 for driving the worm 6-5 is arranged on one side of the worm 6-5. The sampling motor 6-6 is installed on the connecting frame 6-1, and the output shaft of the sampling motor 6-6 is connected to the worm 6-5.

[0045] During use, start the sampling motor 6-6. The sampling motor 6-6 drives the worm 6-5 to rotate. The rotation of the worm 6-5 drives the worm gear 6-4 to rotate. The rotation of the worm gear 6-4 drives the rotating cylinder 6-3 to rotate. During the rotation of the rotating cylinder 6-3, the first driving member 5-2 drives the sampling mechanism 6 to descend, so that the rotating cylinder 6-3 is inserted into the ground, and the rotating cylinder 6-3 samples the soil; When the sampling is completed, move the rotating cylinder 6-3 above the sample storage cylinder 4-4. Then, the third electric cylinder 6-7 drives the push plate 6-8 to descend, pushing out the sample so that the sample falls into the sample storage cylinder 4-4.

[0046] As Figure 10 As shown, the cleaning mechanism 7 includes an installation beam 7-1. Installation plates 7-2 are connected to both the left and right sides of the installation beam 7-1. The installation plates 7-2 are hinged to the chassis 1-1. A bucket 7-3 is hinged to the front side of the installation beam 7-1.

A fifth driving member 7-5 is installed on the chassis 1-1. The other end of the fifth driving member 7-5 is hinged to the installation beam 7-1.

[0047] During use, the height of the bucket 7-3 can be adjusted through the fifth driving member 7-5, and the angle of the bucket 7-3 can be adjusted through the fourth driving member 7-4, so that the bucket 7-3 fits the ground in the sampling area. During the forward movement of the vehicle body 1, the bucket 7-3 clears the vegetation and debris on the soil surface, facilitating the subsequent sampling work.

[0048] The working process of the present invention is as follows:

[0049] First, adjust the position of the bucket 7-3 so that the bucket 7-3 fits the ground of the sampling area. Start the traveling motor 1-5 to drive the vehicle body 1 to move forward. During this process, the bucket 7-3 removes the vegetation and debris on the soil surface. Then, the vertical moving mechanism 5 drives the sampling mechanism 6 to descend. At the same time, the driving component drives the rotating cylinder 6-3 to rotate, so that the rotating cylinder 6-3 is inserted into the ground, and the rotating cylinder 6-3 samples the soil. When the sampling is completed, the second driving member 5-8 drives the moving seat 5-3 to move backward, so that the rotating cylinder 6-3 moves above the sample storage cylinder 4-4. Then, the third electric cylinder 6-7 drives the push plate 6-8 to descend, pushing out the sample so that the sample falls into the sample storage cylinder 4-4. After that, start the rotating motor 4-3. The rotating motor 4-3 drives the gear 4-2 to rotate, and the rotation of the gear 4-2 drives the rotating gear table 4-1 to rotate, thereby rotating another sample storage cylinder 4-4 below the sampling mechanism 6 for the next sample collection.
