After the sampling is completed, the soil sample in the sampler 3 can be directly transported to the mixer 2 for stirring and mixing and divided into multiple sample cups 261. On the one hand, the collected soil samples can be directly divided into the sample cups 261 for manual carrying. On the other hand, it can avoid losses in the process of transferring soil samples to the mixer 2, thereby improving the collection efficiency as a whole.

[0053] Wherein, in some embodiments, reference Figure 1 As shown, the sampler 3 includes a sampling barrel 31 for storing soil samples and a sampling drill 32 connected to the end of the sampling barrel 31 and rotating to drill the soil, and the sampling drill 32 is provided with a sampling port 33 connected to the sampling barrel 31. It can be understood that when sampling is required, the sampling drill 32 can rotate downward to drill the soil, and the soil can enter the sampling barrel 31 through the sampling port 33, thereby obtaining a soil sample.

[0054] Preferably, a thread groove 321 is formed on the side wall of the sampling drill bit 32, and a sawtooth blade 322 is installed at one end facing the soil. It is understandable that when the sampling drill bit 32 rotates downward to drill the soil, the thread groove 321 and the sawtooth blade 322 can cooperate with the sampling drill bit 32, so that the sampling drill bit 32 is easily inserted into the soil and the insertion is more labor-saving.

[0055] Furthermore, if Figure 2 As shown, the sampling tube 31 includes an inner sampling tube 311 connected to the sampling port 33, and an outer sampling tube 312 sleeved on the outer circumference of the inner sampling tube 311.

A plurality of spaced sampling members 4 can be arranged in the spaced gap. The spaced sampling members 4 can be arranged to be able to move toward the inner sampling tube 311 storing the soil sample and to be able to extend into the inner sampling tube 311, so as to collect soil samples at different depths in the inner sampling tube 311 using the spaced sampling members 4.

[0057] And, combined with Figure 2 and Figure 3As shown, the interval sampling member 4 includes a sampling block 41 with a cavity formed inside, a push-pull ring 42 connected to the sampling block 41, and a spring 43 whose end is connected to the push-pull ring 42. A closable opening is provided on the wall of the inner sampling tube 311, and the opening matches the sampling block 41 so that the sampling block 41 can pass through the opening and extend into the inner sampling tube 311 for interval sampling.

[0058] Specifically, combined Figure 2 and Figure 3 As shown, an outlet aligned with the opening is also provided on the outer wall of the outer sampling tube 312. Before the interval sampling, the sampling block 41 is in the gap between the inner sampling tube 311 and the outer sampling tube 312, and the opening on the wall of the inner sampling tube 311 is in the tube wall state, so that the soil sample can be stored in the inner sampling tube 311; when the soil sample is stored in the inner sampling tube 311 and interval sampling is required, the opening on the wall of the inner sampling tube 311 can be opened, and the sampling block 41, under the thrust of the spring 43, passes through the opening and extends into the inner sampling tube 311 for interval sampling; after the interval sampling is completed, the push-pull ring 42 can be pulled to extend the sampling block 41 to the outside through the outlet, so that the operator can take out the sampling block 41 and transport it to the mixer 2 for mixing, stirring and sampling. With such a setting, it is possible to achieve fixed-point sampling of soils at different depths, and the operation is simple.

[0059] Among them, refer to Figure 3 As shown, the end wall of the sampling block 41 facing the inner sampling tube 311 is provided with saw teeth 44. With such a configuration, when the sampling block 41 moves toward the inner sampling tube 311 and extends into the inner sampling tube 311 to collect soil samples, the saw teeth 44 on the end wall can assist in cutting the soil, making it easier for the sampling block 41 to sample the soil sample in the inner sampling tube 311.

[0060] Wherein, in some embodiments, combined Figure 1 As shown, the sampling drilling assembly also includes a rotating motor 51 connected to the sampler 3 and driving the sampler 3 to rotate, and a hydraulic structure 6 connected to the rotating motor 51 and driving the sampler to move up and down.

The soil sample entering the mixer 2 through the feed port 21 is uniformly stirred and mixed under the action of the stirring structure 22, and then screened and packaged through the quantitative screening structure 23 to achieve sample separation. Figure 5 As shown, when the stirring structure 22 is working, the movable bottom plate 24 is connected to the side wall of the mixer 2 to ensure that the soil sample will not fall into the quantitative screening structure 23 during the stirring process; when the stirring is completed, the controller 25 can be used to manipulate the movable bottom plate 24 to move, so that the stirred soil sample falls into the quantitative screening structure 23 for screening and packaging.

[0064] Further, refer to Figure 5 As shown, the stirring structure 22 includes a rotating shaft 221 rotatably connected to the center of the mixer 2 and extending vertically, and a plurality of stirring rods 222 connected to the outer peripheral side wall of the rotating shaft 221 and extending horizontally. The bottom end of the rotating shaft 221 is connected to the movable bottom plate 24.

[0065] Specifically, Figure 5 As shown, the motor 223 drives the rotating shaft 221 to rotate, thereby driving the plurality of stirring rods 222 to rotate, stirring the soil sample so that the soil sample is evenly mixed.

[0066] And, if Figure 5 As shown, the quantitative screening structure 23 includes a screen 231, a plurality of distribution ports 232 arranged below the screen 231, and a placement box 26 connected to the distribution ports 232, and a plurality of sample cups 261 are arranged in the placement box 26 and aligned with the distribution ports 232 respectively.

[0067] Specifically, the soil sample that has been mixed and stirred evenly can fall into the sieve 231 for screening to detect whether the soil sample meets the detection requirements. The sieved soil sample falls into the sampling cup 261 through the sampling port 232, wherein the sampling cup 261 is provided with a weight sensor, which can sense the weight of the soil sample stored in the sampling cup 261. After the weights of the sampling cups 261 are consistent, the sampling port 232 can be controlled to close to ensure the uniformity and accuracy of the packaging.
