At this time, the trapezoidal sliding block 14 contacts the inclined surface of the trapezoidal sliding block 18, and the trapezoidal sliding block 14 will squeeze the trapezoidal sliding block 8 to slide toward the inside of the installation box 6. When the trapezoidal sliding block 14 moves above the trapezoidal sliding block 8, the elastic force of the spring 10 will make the trapezoidal sliding block 8 quickly reset, and at the same time, it will also block the bottom of the trapezoidal sliding block 14. The outside of the sliding block 13 is fixedly connected with two trapezoidal sliding blocks 14. Three positioning components are installed on the outside of the sampler 1. After the soil sampling is completed, the paddles at the bottom of the two trapezoidal sliding blocks 8 are toggled to drive the two trapezoidal sliding blocks 8 to move and move away from the bottom of the trapezoidal sliding block 14. At this time, the elastic force accumulated by the spring 12 will push the sliding block 13 to move downward, which can discharge the soil in the sampling head 11, and there is no need to use other tools to dig out the soil. This operation will be more convenient.

[0025] Reference Figure 1 and Figure 5The positioning assembly includes two fixed plates 15, the outer sides of the two fixed plates 15 are fixedly connected to the outer side of the sampler 1, the adjacent sides of the two fixed plates 15 are rotatably connected with a rotating ring 16, the inner side of the rotating ring 16 is rotatably connected with a rotating block 18, one end of the rotating block 18 is fixedly connected with two insertion rods 19, the sampling device can be carried to the sample soil area, the three latches 22 are lifted upward, the rotating ring 16 is rotated to make the rotating ring 16 horizontal, the rotating block 18 is rotated downward under the action of gravity, and then the insertion rod 19 is inserted The sampler 1 can be positioned in the soil.

Three fixed blocks 21 are fixedly connected to the outside of the sampler 1. A latch 22 is slidably connected to the inside of the fixed block 21. A clamping hole 23 is provided at one end of the rotating ring 16. The bottom end of the latch 22 is clamped in the inside of the clamping hole 23. Three grooves are provided on the outside of the sampler 1, and a magnetic block 20 is fixedly connected inside the groove.

The rotating block 18 rotates downward under the action of gravity, and then the insertion rod 19 is inserted into the soil for positioning, and then the hydraulic cylinder 3 is started to move the connecting head 4 downward, so that the sampling head 11 will be inserted into the soil. After being subjected to pressure, the inside of the sampling head 11 will continue to enter the soil, and the sliding block 13 will be pushed to drive the two trapezoidal sliding blocks 14 to move upward. After the trapezoidal slider 2 14 contacts the inclined surface of the trapezoidal slider 1 8, the trapezoidal slider 1 8 is squeezed to move toward the inside of the installation box 6. When the trapezoidal slider 2 14 is separated from the trapezoidal slider 1 8, the elastic force of the spring 10 will reset the trapezoidal slider 1 8 and block the trapezoidal slider 2 14. When the sampling is completed, the paddles at the bottom of the two trapezoidal sliders 8 are moved to release the restriction on the trapezoidal slider 2 14. The elastic force of the spring 2 12 will push the sliding block 13 to move downward and discharge the sampled soil, so it is more convenient to remove the sampled soil.
