[0029] As a preferred embodiment of the utility model, it may also have the following additional technical features: the moving wheel group 31 includes a first moving wheel 311, a second moving wheel 312 and a steering wheel 313, the first moving wheel 311 and the second moving wheel 312 are symmetrically arranged, the first drive motor 32 is connected to the first moving wheel 311 and the second moving wheel 312, the steering wheel 313 is arranged at one end of the aggregate structure 2 away from the first moving wheel 311 and the second moving wheel 312, and the steering wheel 313 is connected to the second drive motor 33. In this embodiment, the first drive motor 32 controls the first moving wheel 311 and the second moving wheel 312 to move forward or backward, and the second drive motor 33 is used to control the rotation of the steering wheel 313, thereby adjusting the moving direction of the soil sampling device in this embodiment, so as to facilitate soil sampling in different places.

[0030] As a preferred embodiment of the utility model, it may also have the following additional technical features: a plurality of anti-skid protrusions 314 are provided on the first moving wheel 311, the second moving wheel 312 and the steering wheel 313. In the soil sampling environment, the grip of the tire is very important. A plurality of anti-skid protrusions 314 are provided to increase the friction between the tire and the soil, thereby ensuring the stability of the soil sampling device of this embodiment when moving.

[0031] As a preferred embodiment of the utility model, it may also have the following additional technical features: the radius of the steering wheel 313 is smaller than the radius of the first moving wheel 311 and the second moving wheel 312. Since the soil may be relatively soft, the soil sampling device of this embodiment may slip or sink when moving. In order to increase driving stability, larger first moving wheels 311 and second moving wheels 312 are selected to provide better support. The larger first moving wheels 311 and second moving wheels 312 can provide better traction to help the vehicle travel in soft soil. At the same time, the size of the steering wheel 313 should also be moderate to ensure the stability of the vehicle when turning.

[0032] As a preferred embodiment of the utility model, it may also have the following additional technical features: the sampling mechanism 1 includes a sampling barrel 11, a sampling structure 12 and a driving device 13, the sampling structure 12 and the driving device 13 are arranged in the sampling barrel 11, the sampling structure 12 is connected to the driving device 13, the sampling structure 12 can rotate in the sampling barrel 11, and a discharge port 111 is provided on the sampling barrel 11, and the discharge port 111 is connected to the aggregate structure 2. When the driving device 13 is in operation, the sampling structure 12 is driven to rotate and thereby collect soil. The soil rises in the sampling structure 12 to reach the discharge port 111 and then falls into the aggregate structure 2 for collection.

[0033] As a preferred embodiment of the utility model, it may also have the following additional technical features: the sampling structure 12 includes a rotating rod 121 and a spiral plate 122, the rotating rod 121 is connected to the driving device 13, the spiral plate 122 is arranged around the rotating rod 121, the spiral plate 122 is fixedly connected to the rotating rod 121, the driving device 13 controls the rotation of the rotating rod 121 and then drives the spiral plate 122 to rotate together, thereby realizing the sampling and collection of soil. In this embodiment, the side of the spiral plate 122 away from the rotating rod 121 abuts against the inner wall of the sampling tube 11, effectively preventing the sampled soil from falling during the rising process, thereby affecting the amount of soil sampling.

[0034] As a preferred embodiment of the utility model, it may also have the following additional technical features: the driving device 13 includes a rotating motor 131 and a lifting structure 132, the rotating motor 131 is connected to the lifting structure 132, the lifting structure 132 is connected to the sampling tube 11, and the end of the rotating motor 131 away from the lifting structure 132 is connected to the sampling structure 12. In this embodiment, the rotating motor 131 is used to control the rotation of the sampling structure 12 to achieve soil sampling, and the lifting structure 132 is used to control the forward and backward movement of the sampling structure 12 to achieve the insertion of the sampling structure 12 into the soil.

[0035] As a preferred embodiment of the utility model, it may also have the following additional technical features: the end of the rotating rod 121 away from the driving device 13 is set to be conical, and the conical design can reduce the resistance encountered by the soil sampling device during the insertion process. When the tip of the sampling device encounters the soil, the conical structure can effectively disperse the soil to avoid forming a blocking point, thereby reducing the resistance during insertion. Since the conical design can reduce resistance and improve penetration, it can improve the accuracy of soil sampling. During the sampling process, the conical structure can make the sampling device more stably inserted into the soil, avoiding deviations caused by resistance, thereby ensuring the accuracy and reliability of sampling, and enabling the soil sampling device to collect a wider range of soil samples. As the sampling device is inserted, the conical structure can gradually gather the surrounding soil to the center of the sampling device, ensuring that a more comprehensive soil sample is collected.

[0036] As a preferred embodiment of the utility model, it may also have the following additional technical features: a water inlet 112 is provided on one end of the sampling tube 11 close to the driving device 13, and the water inlet 112 is provided above the sampling structure 12. The water inlet 112 is connected to an external high-pressure water pump. When soil sampling is completed, the sampling structure 12 needs to be cleaned in time. At this time, the high-pressure water pump is started to pass clean water into the sampling tube 11 from the water inlet 112 to ensure that the sampling structure 12 has been thoroughly cleaned before the next use to reduce the risk of contamination of the soil sample.

[0037] Specifically, in this embodiment, the sampling tube 11 is tilted on the aggregate device, and the angle between the sampling tube 11 and the ground is 45°. The tilted inserted sampling tube 11 will produce a certain pressure on the soil, which helps to stimulate and promote the growth of the root system. At the same time, it can make the air circulation in the soil smoother, which is beneficial to improve the soil's air permeability, thereby improving the soil's water retention and nutrient utilization efficiency.

[0038] As a preferred embodiment of the utility model, it may also have the following additional technical features: the aggregate structure 2 includes an outer shell 21 and an aggregate barrel 22, the aggregate barrel 22 is arranged in the outer shell 21, the discharge port 111 is connected to the aggregate barrel 22, the moving component 3 is arranged on the outer shell 21, the outer shell 21 is provided with an opening, and the opening is provided with an anti-fouling structure 23, which is used to protect the soil in the aggregate barrel 22 from being contaminated and ensure the accuracy of the soil inspection results.

[0039] As a preferred embodiment of the utility model, it may also have the following additional technical features: the anti-fouling structure 23 includes an anti-fouling cover 231 and a sealing member 232, the sealing member 232 is arranged between the anti-fouling cover 231 and the opening, the anti-fouling cover 231 is detachably connected to the outer shell 21, and when the soil is in the sampling process, the anti-fouling cover 231 should be kept tightly closed to ensure that the soil is not contaminated. When the soil sampling is completed, the anti-fouling cover 231 is opened and the collecting barrel 22 is taken out.

[0040] As a preferred embodiment of the utility model, it may also have the following additional technical features: a remote control device 4 is arranged on the aggregate structure 2, and the remote control device 4 is electrically connected to the drive device 13 and the moving component 3 respectively, and can control the operation of the drive device 13 to sample the soil. At the same time, when it is necessary to change different places for soil sampling, it can control the operation of the first drive motor 32 and the second drive motor 33, and then control the forward and backward movement of the first moving wheel 311 and the second moving wheel 312, and control the rotation of the steering wheel 313.

[0041] The working principle of the soil sampling device of this embodiment is as follows: first, the remote control device 4 is used to control the movement of the mobile component 3, so that the soil sampling device moves to the designated place to wait for soil sampling, and then, the rotating motor 131 is started to make the rotating rod 121 start to rotate. At this time, the rotating rod 121 is inserted into the soil through the lifting structure 132 to collect the soil on the spiral plate 122. With the rotation of the rotating rod 121 and the cooperation of the lifting structure 132, the soil on the rotating plate continues to move upward until it falls from the discharge port 111 into the collecting barrel 22. After the sampling is completed, the anti-fouling cover 231 is opened and the collecting barrel 22 is taken out. Finally, when all operations are completed, a high-pressure water pump is used to connect with the water inlet 112, and clean water is introduced to fully clean the sampling barrel 11 and the sampling structure 12 to ensure that the next sampling is not affected.

[0042] The soil sampling device of this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements.
