Description

Technical Field

[0001] The utility model relates to the field of soil specimen sampling devices, in particular to a soil specimen sampling structure. Background Art

[0002] The collection of soil specimens is an important link in soil analysis work. Since there are differences in soil components between different soil layers or at different positions within the same area, it is necessary to collect soil at different positions one by one to improve the accuracy of the collected data.

[0003] The patent with the publication number CN207163735U discloses a soil specimen collection device. A bracket is fixed on the side wall of the sleeve. A collection cylinder is slidably arranged inside the sleeve. A collection cavity is arranged through the collection cylinder. The collection cylinder is connected to a rotating rod through a bearing. One end of the rotating rod is fixedly connected to a turntable, and the other end passes through the collection cylinder and is rotatably connected to a cover plate arranged at the lower end of the collection cylinder. An annular blade is fixed on the circumferential side of the cover plate. A support rod and a pedal are arranged at the upper end of the collection cylinder. Place the sleeve on the surface of the soil to be sampled. The bracket supports on the soil surface and presses down the collection cylinder inside the sleeve. When the collection cylinder penetrates into the soil, the soil specimen enters the collection cavity. At this time, twist the rotating rod to drive the cover plate to rotate and close the lower port of the collection cavity. After the collection is completed, lift the collection cylinder. During the process of sampling soil specimens, the soil specimens may adhere to the inner wall of the collection cylinder. Since the collection device does not have a structure for pushing out the soil specimens, it is necessary to use other tools to take out the soil specimens. And because the structure of the collection device is complex, it is not convenient for the staff to carry, thus reducing the work efficiency.

[0004] In view of this, during the process of sampling soil specimens, how to realize taking out the soil specimens by the device, making it convenient for the staff to carry the device and improving the work efficiency has become a technical problem that needs to be solved urgently by those skilled in the art.

[0029] The limiting member 5 is a limiting ring 51, and the limiting ring 51 is fixedly connected to the outer side wall of the connecting rod 3.

[0030] During use, place the sampling box 1 on the surface of the soil to be sampled, tap the sampling box 1 to press it into the soil, so that the sampling box 1 penetrates into the soil. When the soil fills the inside of the sampling box 1, take out the sampling box 1, flatten the bottom surface of the sampling box 1, push the push-pull head 2 to drive the sliding of the connecting rod 3, so as to realize that the soil pushing plate 4 pushes out the soil specimen from the sampling box 1 and complete the sampling work.
