[0003] In order to ensure the accuracy of soil sampling data, testers often take samples of soil from multiple locations in the same area. Existing soil sampling tubes can only take samples once. After sampling the soil at a certain location, they will move to another location for sampling. The operation process takes a lot of time, resulting in low efficiency in soil testing, which needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In this embodiment, refer to Figure 1-3 A soil sampling device for safe utilization of cultivated land includes a control box 1. The interior of the control box 1 is hollow and designed as an installation cavity 16. A lifting plate 5 that slides up and down is installed inside the installation cavity 16 through a screw drive. The control box 1 is provided with a vertical mounting platform 2 in its installation cavity 16. A screw rod 3 is rotatably installed in the mounting platform 2. A nut pair 11 is threadedly connected to the screw rod 3. The outer end surface of the nut pair 11 is fixedly connected to the corresponding plate surface of the lifting plate 5. A transmission motor 4 that drives the screw rod 3 to rotate is provided on the top of the mounting platform 2.

[0021] In addition, sliding blocks 14 are respectively arranged on both sides of the lifting plate 5, and correspondingly, vertical grooves for the sliding blocks 14 to slide up and down are respectively reserved on both sides of the inner wall of the installation cavity 16. The lifting plate 5 can be controlled to slide up and down by a screw transmission.

[0022] An odd number of vertical sliding posts 7 are slidably connected to the interior of the installation cavity 16 at the front side of the lifting plate 5. Figure 1 or attached Figure 2 It can be seen that a plurality of support rods 6 arranged in parallel up and down are arranged inside the installation cavity 16 on the front side of the lifting plate 5, and the sliding column 7 is slidably mounted on the support rod 6 and slides along the length direction of the rod body. The sliding columns 7 on both sides maintain a symmetrical relationship with the middle sliding column 7 as the axis.

[0023] The front side plate surface of the lifting plate 5 is provided with a plurality of guide grooves 13, wherein the guide groove 13 in the middle is a vertical groove, and the guide grooves 13 on both sides maintain a symmetrical relationship with the middle guide groove 13 as the axis. It should be particularly noted that the sliding column 7 and the guide groove 13 in the center are opposite to each other, while the sliding columns 7 and the guide grooves 13 on both sides maintain a one-to-one correspondence. Figure 3 As shown, the sliding blocks 14 arranged on the inner surface of each sliding column 7 are respectively embedded in the corresponding guide grooves 13 and slide along them.

[0024] When the height position of the lifting plate 5 changes, the sliding balls 12 on the sliding posts 7 slide in the guide grooves 13 on the lifting plate 5, so the sliding posts 7 on the front side will move relative to each other, and the specific movement is as follows: they move together toward the middle or apart toward the outside at the same time.

[0025] A cylinder 8 is provided at the bottom of the sliding column 7, and a sampler 9 is installed at the bottom output end of the cylinder 8. The sampler 9 extends downward from the bottom wall of the control box 1 and extends into the soil to take samples. A sampling tube 15 for accommodating the sampled soil is provided at the bottom of the sampler 9.

[0026] The control box 1 is provided with supporting legs 10 at the bottom. The control box 1 is erected above the soil through the supporting legs 10 and sampling is performed using a sampler 9 extending from the bottom of the control box 1 .

[0027] In the actual sampling process, when facing a regional test plot, if the area of ​​the soil to be tested is large, the staff can start the transmission motor 4 to control the adjacent samplers 9 below to be separated by a larger distance, wait until the position of the sampler 9 is adjusted, and then start each cylinder 8 synchronously, so that the sampler 9 extends downward into the soil and samples, and the sampled soil is finally built into the sampling tube 15 and recovered. Similarly, if the area of ​​the soil to be tested is small, the staff only needs to start the transmission motor 4 to control the adjacent samplers 9 below to be separated by a smaller distance.

[0028] When sampling soil in different areas, the staff can reasonably divide the spacing between the sampling tubes according to the size of the soil distribution area, and multiple samplers 9 can collect soil at the same time, thereby greatly improving the efficiency of the sampling work, and ultimately improving the efficiency of soil sampling and detection.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
